Payroll tax withholding rates and other information effective January 1, 2025, are summarized.

Payroll tax withholding rates and other information effective January 1, 2025, are summarized as follows:

 1.  FEDERAL INSURANCE CONTRIBUTION ACT (FICA)

The Social Security or OASDI wage base for 2025 is $176,100 ($168,600 in 2024). Both the employer and employee 2025 OASDI tax rate is 6.2%. The maximum 2025 OASDI tax per employee will be $10,918.20. The Medicare Hospital Insurance or HI wage base is unlimited. The employer and employee's HI tax rate will be 1.45%, each. A single taxpayer will pay an additional HI tax of 0.9% on wages in excess of $200,000 ($250,000 for married persons filing jointly).

 2.  CALIFORNIA DISABILITY INSURANCE (SDI)

The CA SDI withholding rate for 2025 is 1.2% (1.1% in 2024). Effective January 1, 2024, Senate Bill 951 removes the taxable wage limit. Thus, there is no maximum withholding for each employee subject to SDI contributions for 2025.

 3.  SELF-EMPLOYMENT TAX

The 2025 wage base for self-employment OASDI tax is $176,100 ($168,600 in 2024). The self-employment HI tax wage base is unlimited. The 2025 annualized OASDI and HI self-employed tax rate on the first $176,100 of taxable self-employment earnings will be 15.3% (OASDI at 12.4% and HI at 2.9%). The maximum 2025 OASDI and HI tax is $26,943.30 on the first $176,100 of taxable self-employment earnings. A single taxpayer will pay an additional HI tax of 0.9% on taxable self-employment income in excess of $200,000 ($250,000 for married persons filing jointly).

 4.  FEDERAL UNEMPLOYMENT TAX (FUTA)

FUTA rate in California for 2024 is 1.50%.  Employers in California pay 1.50% FUTA tax on wages up to the first $7,000 per employee, which is an additional $63 per employee compared to the usual 0.6% rate. For 2025, the FUTA rate in California is expected to be 1.80%.  This means employers are expected to pay 1.80% FUTA tax on the first $7,000 of wages per employee in 2025, which is an additional $21 per employee compared to 2024.  Total FUTA tax per employee for 2025 would be $126.

 5.  SUPPLEMENTAL WAGE WITHHOLDING

Employers may either (1) add supplemental wage payments (bonuses, commissions, or other types of supplemental pay) to regular wages and compute a withholding amount or (2) apply a flat percentage to the supplemental wage amount without allowance for exemptions or credits. The 2025 Federal flat withholding rate on supplemental wages of $1.0 million or less is expected to remain 22% (37% if the supplemental payment exceeds $1.0 million). The 2025 California flat withholding rate is expected to remain at 6.6% for supplemental wages and 10.23% for bonus payments and stock option exercise income

6.  401K RETIREMENT PLAN CONTRIBUTIONS

In 2025, the 401K maximum employee deferral is $23,500 ($23,000 in 2024). A "catch-up" deferral for those ages 50 and over for 2025 is an additional $7,500 of wages ($7,500 in 2024).  Starting in 2025, under a change made in SECURE 2.0, a higher catch-up contribution limit applies for employees aged 60, 61, 62 and 63 who participate in these plans.  For 2025, this higher catch-up contribution limit is $11,250 instead of $7,500.

The Internal Revenue Service is looking toward automated solutions to cover the recent workforce reductions implemented by the Trump Administration, Department of the Treasury Secretary Bessent told a House Appropriations subcommittee.

The Internal Revenue Service is looking toward automated solutions to cover the recent workforce reductions implemented by the Trump Administration, Department of the Treasury Secretary Bessent told a House Appropriations subcommittee.

During a May 6, 2025, oversight hearing of the House Appropriations Financial Services and General Government Subcommittee, Bessent framed the current employment level at the IRS as “bloated” and is using the workforce reduction as a means to partially justify the smaller budget the agency is looking for.

“We are just taking the IRS back to where it was before the IRA [Inflation Reduction Act] bill substantially bloated the personnel and the infrastructure,” he testified before the committee, adding that “a large number of employees” took the option for early retirement.

When pressed about how this could impact revenue collection activities, Bessent noted that the agency will be looking to use AI to help automate the process and maintain collection activities.

“I believe, through smarter IT, through this AI boom, that we can use that to enhance collections,” he said. “And I would expect that collections would continue to be very robust as they were this year.”

He also suggested that those hired from the supplemental funding from the IRA to enhance enforcement has not been effective as he pushed for more reliance on AI and other information technology resources.

There “is nothing that shows historically that by bringing in unseasoned collections agents … results in more collections or high-end collections,” Bessent said. “It would be like sending in a junior high school student to try to a college-level class.”

Another area he highlighted where automation will cover workforce reductions is in the processing of paper returns and other correspondence.

“Last year, the IRS spent approximately $450 million on paper processing, with nearly 6,500 full-time staff dedicated to the task,” he said. “Through policy changes and automation, Treasury aims to reduce this expense to under $20 million by the end of President Trump’s second term.”

Bessent’s testimony before the committee comes in the wake of a May 2, 2025, report from the Treasury Inspector General for Tax Administration that highlighted an 11-percent reduction in the IRS workforce as of February 2025. Of those who were separated from federal employment, 31 percent of revenue agents were separated, while 5 percent of information technology management are no longer with the agency.

When questioned about what the IRS will do to ensure an equitable distribution of enforcement action, Bessent stated that the agency is “reviewing the process of who is audited at the IRS. There’s a great deal of politicization of that, so we are trying to stop that, and we are also going to look at distribution of who is audited and why they are audited.”

Bessent also reiterated during the hearing his support of making the expiring provisions of the Tax Cuts and Jobs Act permanent.

A taxpayer's passport may be denied or revoked for seriously deliquent tax debt only if the taxpayer's tax liability is legally enforceable. In a decision of first impression, the Tax Court held that its scope of review of the existence of seriously delinquent tax debt is de novo and the court may hear new evidence at trial in addition to the evidence in the IRS's administrative record.

A taxpayer's passport may be denied or revoked for seriously deliquent tax debt only if the taxpayer's tax liability is legally enforceable. In a decision of first impression, the Tax Court held that its scope of review of the existence of seriously delinquent tax debt is de novo and the court may hear new evidence at trial in addition to the evidence in the IRS's administrative record.

The IRS certified the taxpayer's tax liabilities as "seriously delinquent" in 2022. For a tax liability to be considered seriously delinquent, it must be legally enforceable under Code Sec. 7345(b).

The taxpayer's tax liabilities related to tax years 2005 through 2008 and were assessed between 2007 and 2010. The standard collection period for tax liabilities is ten years after assessment, meaning that the taxpayer's liabilities were uncollectible before 2022, unless an exception to the statute of limitations applied. The IRS asserted that the taxpayer's tax liabilities were reduced to judgment in a district court case in 2014, extending the collections period for 20 years from the date of the district court default judgment. The taxpayer maintained that he was never served in the district court case and the judgment in that suit was void.

The Tax Court held that its review of the IRS's certification of the taxpayer's tax debt is de novo, allowing for new evidence beyond the administrative record. A genuine issue of material fact existed whether the taxpayer was served in the district court suit. If not, his tax debts were not legally enforceable as of the 2022 certification, and the Tax Court would find the IRS's certification erroneous. The Tax Court therefore denied the IRS's motion for summary judgment and ordered a trial.

The IRS has reminded taxpayers that disaster preparation season is kicking off soon with National Wildfire Awareness Month in May and National Hurricane Preparedness Week between May 4 and 10. Disasters impact individuals and businesses, making year-round preparation crucial. 

The IRS has reminded taxpayers that disaster preparation season is kicking off soon with National Wildfire Awareness Month in May and National Hurricane Preparedness Week between May 4 and 10. Disasters impact individuals and businesses, making year-round preparation crucial. In 2025, FEMA declared 12 major disasters across nine states due to storms, floods, and wildfires. Following are tips from the IRS to taxpayers to help ensure record protection:

• Store original documents like tax returns and birth certificates in a waterproof container;
• keep copies in a separate location or with someone trustworthy. Use flash drives for portable digital backups; and
• use a phone or other devices to record valuable items through photos or videos. This aids insurance or tax claims. IRS Publications 584 and 584-B help list personal or business property.

Further, reconstructing records after a disaster may be necessary for tax purposes, insurance or federal aid. Employers should ensure payroll providers have fiduciary bonds to protect against defaults, as disasters can affect timely federal tax deposits.

A decedent's estate was not allowed to deduct payments to his stepchildren as claims against the estate.

A decedent's estate was not allowed to deduct payments to his stepchildren as claims against the estate.

A prenuptial agreement between the decedent and his surviving spouse provided for, among other things, $3 million paid to the spouse's adult children in exchange for the spouse relinquishing other rights. Because the decedent did not amend his will to include the terms provided for in the agreement, the stepchildren sued the estate for payment. The tax court concluded that the payments to the stepchildren were not deductible claims against the estate because they were not "contracted bona fide" or "for an adequate and full consideration in money or money's worth" (R. Spizzirri Est., Dec. 62,171(M), TC Memo 2023-25).

The bona fide requirement prohibits the deduction of transfers that are testamentary in nature. The stepchildren were lineal descendants of the decedent's spouse and were considered family members. The payments were not contracted bona fide because the agreement did not occur in the ordinary course of business and was not free from donative intent. The decedent agreed to the payments to reduce the risk of a costly divorce. In addition, the decedent regularly gave money to at least one of his stepchildren during his life, which indicated his donative intent. The payments were related to the spouse's expectation of inheritance because they were contracted in exchange for her giving up her rights as a surviving spouse. As a results, the payments were not contracted bona fide under Reg. §20.2053-1(b)(2)(ii) and were not deductible as claims against the estate.

The IRS issued interim final regulations on user fees for the issuance of IRS Letter 627, also referred to as an estate tax closing letter. The text of the interim final regulations also serves as the text of proposed regulations.These regulations reduce the amount of the user fee imposed to $56.

The IRS issued interim final regulations on user fees for the issuance of IRS Letter 627, also referred to as an estate tax closing letter. The text of the interim final regulations also serves as the text of proposed regulations.These regulations reduce the amount of the user fee imposed to $56.

Background

In 2021, the Treasury and Service established a $67 user fee for issuing said estate tax closing letter. This figure was based on a 2019 cost model.

In 2023, the IRS conducted a biennial review on the same issue and determined the cost to be $56. The IRS calculates the overhead rate annually based on cost elements underlying the statement of net cost included in the IRS Annual Financial Statements, which are audited by the Government Accountability Office.

Current Rate

For this fee review, the fiscal year (FY) 2023 overhead rate, based on FY 2022 costs, 62.50 percent was used. The IRS determined that processing requests for estate tax closing letters required 9,250 staff hours annually. The average salary and benefits for both IR paybands conducting quality assurance reviews was multiplied by that IR payband’s percentage of processing time to arrive at the $95,460 total cost per FTE.

The Service stated that the $56 fee was not substantial enough to have a significant economic impact on any entities. This guidance does not include any federal mandate that may result in expenditures by state, local, or tribal governments, or by the private sector in excess of that threshold.

The Tax Court appropriately dismissed an individual's challenge to his seriously delinquent tax debt certification. The taxpayer argued that his passport was restricted because of that certification. However, the certification had been reversed months before the taxpayer filed this petition. Further, the State Department had not taken any action on the basis of the certification before the taxpayer filed his petition.

Further, the State Department had not taken any action on the basis of the certification before the taxpayer filed his petition.

Additionally, the Tax Court correctly dismissed the taxpayer’s challenge to the notices of deficiency as untimely. The taxpayer filed his petition after the 90-day limitation under Code Sec. 6213(a) had passed. Finally, the taxpayer was liable for penalty under Code Sec. 6673(a)(1). The Tax Court did not abuse its discretion in concluding that the taxpayer presented classic tax protester rhetoric and submitted frivolous filings primarily for purposes of delay.

The 2025 cost-of-living adjustments (COLAs) that affect pension plan dollar limitations and other retirement-related provisions have been released by the IRS. In general, many of the pension plan limitations will change for 2025 because the increase in the cost-of-living index due to inflation met the statutory thresholds that trigger their adjustment. However, other limitations will remain unchanged.

The IRS has released the 2024-2025 special per diem rates. Taxpayers use the per diem rates to substantiate certain expenses incurred while traveling away from home. These special per diem rates include:

The IRS has released the 2024-2025 special per diem rates. Taxpayers use the per diem rates to substantiate certain expenses incurred while traveling away from home. These special per diem rates include:

1. the special transportation industry meal and incidental expenses (M&IE) rates,
2. the rate for the incidental expenses only deduction,
3. and the rates and list of high-cost localities for purposes of the high-low substantiation method.

Transportation Industry Special Per Diem Rates

The special M&IE rates for taxpayers in the transportation industry are:

• $80 for any locality of travel in the continental United States (CONUS), and
• $86 for any locality of travel outside the continental United States (OCONUS).

Incidental Expenses Only Rate

The rate is $5 per day for any CONUS or OCONUS travel for the incidental expenses only deduction.

High-Low Substantiation Method

For purposes of the high-low substantiation method, the 2024-2025 special per diem rates are:

• $319 for travel to any high-cost locality, and
• $225 for travel to any other locality within CONUS.

The amount treated as paid for meals is:

• $86 for travel to any high-cost locality, and
• $74 for travel to any other locality within CONUS.

Instead of the meal and incidental expenses only substantiation method, taxpayers may use:

• $86 for travel to any high-cost locality, and
• $74 for travel to any other locality within CONUS.

Taxpayers using the high-low method must comply with Rev. Proc. 2019-48, I.R.B. 2019-51, 1392. That procedure provides the rules for using a per diem rate to substantiate the amount of ordinary and necessary business expenses paid or incurred while traveling away from home.

Notice 2024-68

The IRS has launched a new initiative to improve tax compliance among high-income taxpayers who have not filed federal income tax returns since 2017.

The IRS has launched a new initiative to improve tax compliance among high-income taxpayers who have not filed federal income tax returns since 2017. This effort, funded by the Inflation Reduction Act, involves sending out IRS compliance letters to over 125,000 cases where tax returns have not been filed since 2017. These mailings include more than 25,000 to individuals with incomes exceeding $1 million and over 100,000 to those with incomes ranging between $400,000 and $1 million for the tax years 2017 to 2021. The IRS will begin mailing these compliance alerts, formally known as the CP59 Notice, this week.

Recipients of these letters should act promptly to prevent further notices, increased penalties, and stronger enforcement actions. Consulting a tax professional can help them swiftly file late tax returns and settle outstanding taxes, interest, and penalties. The failure-to-file penalty is 5 percent per month, capped at 25 percent of the tax owed. Additional resources are available on the IRS website for non-filers.

The non-filer initiative is part of the IRS's broader campaign to ensure large corporations, partnerships, and high-income individuals fulfill their tax obligations. Non-respondents to the non-filer letter will face further notices and enforcement actions. If someone consistently ignores these notices, the IRS may file a substitute tax return on their behalf. However, it's still advisable for the individual to file their own return to claim eligible exemptions, credits, and deductions.

Some members of the military may also use these rates to compute their moving expense deductions.

2024 Standard Mileage Rates

The standard mileage rates for 2024 are:

• 67 cents per mile for business uses;
• 21 cents per mile for medical uses; and
• 14 cents per mile for charitable uses.

Taxpayers may use these rates, instead of their actual expenses, to calculate their deductions for business, medical or charitable use of their own vehicles.

FAVR Allowance for 2024

For purposes of the fixed and variable rate (FAVR) allowance, the maximum standard automobile cost for vehicles places in service after 2023 is:

• $62,000 for passenger automobiles, and
• $62,000 for trucks and vans.

Employers can use a FAVR allowance to reimburse employees who use their own vehicles for the employer’s business.

2024 Mileage Rate for Moving Expenses

The standard mileage rate for the moving expense deduction is 21 cents per mile. To claim this deduction, the taxpayer must be:

• a member of the Armed Forces of the United States,
• on active military duty, and
• moving under an military order and incident to a permanent change of station

The Tax Cuts and Jobs Act of 2017 suspended the moving expense deduction for all other taxpayers until 2026.

Unreimbursed Employee Travel Expenses

For most taxpayers, the Tax Cuts and Jobs Act suspended the miscellaneous itemized deduction for unreimbursed employee travel expenses. However, certain taxpayers may still claim an above-the-line deduction for these expenses. These taxpayers include:

• members of a reserve component of the U.S. Armed Forces,
• state or local government officials paid on a fee basis, and
• performing artists with relatively low incomes.

The IRS reminded taxpayers that their website (www.irs.gov) provides millions of visitors with the answers they need to fit their busy summer schedules.

The IRS reminded taxpayers that their website ( www.irs.gov) provides millions of visitors with the answers they need to fit their busy summer schedules. Taxpayers who requested an extension to October 15 or missed the May 17 deadline can still prepare and e-file tax returns for free with the IRS Free File tool. Further, taxpayers can view, download or print tax products, and do the following:

Use the "File" tab on the home page for most federal income tax needs. Access the Interactive Tax Assistant tool that can answer many tax law questions.
See their tax account with the View Your Account tool. With this, they can find information such as a payoff amount, the balance for each tax year owed, up to 24 months of their payment history and key information from their current tax year return as originally filed.
Use the Get Transcript tool to view, print or download their tax transcripts after the IRS has processed the return.
Find the most up-to-date information about tax refunds using the Where's My Refund? tool on the IRS website and on the official IRS mobile app, IRS2Go. Taxpayers can start checking on the status of their refund 24 hours after the IRS acknowledges receipt of an e-filed return.
Additionally, many pages on the IRS website are now available in Spanish, Vietnamese, Russian, Korean, Haitian, Creole, and Chinese—simplified and traditional. Earlier this year, the agency posted a Spanish language version of Form 1040 PDF and the related instructions.

Assistive Technology
Moreover, at the online Alternative Media Center (AMC), taxpayers can find a variety of accessible products like screen reading software, refreshable Braille displays, and screen magnifying software. These products include tax forms, instructions, and publications that can be downloaded or viewed online as Section 508 compliant PDF, HTML, eBraille, text, and large print. However, every product is not available in all formats. For example, tax forms are not available as HTML. To request paper copies of tax forms, instructions or publications in Braille or large print, taxpayers must call the tax form telephone number at 800-829-3676.

Coronavirus Tax Relief Information
Further, the IRS has published ready-to-use articles, e-posters, videos, and much more on the website about Economic Impact Payments, the Recovery Rebate Credit, and the Advance Child Tax Credit. The IRS placed a special emphasis on partnering with organizations that work with groups focusing on veterans, homeless and low-income taxpayers as well as non-English speaking audiences to share information. In all, the IRS worked with thousands of partners across the country reaching organizations representing hundreds of millions of taxpayers.

IRS Tax Withholding Estimator
Finally, the IRS Tax Withholding Estimator helps employees assess their income tax, credits, adjustments and deductions and determine whether they need to change their withholding by submitting a new Form W-4, Employee's Withholding Allowance Certificate. However, taxpayers should remember that, if needed, they should submit their new W-4 to their employer, not the IRS.

The Tax Cuts and Jobs Act modifies Section 529 qualified tuition plans to allow the plans to distribute up to $10,000 in tuition expenses incurred during the tax year for designated beneficiaries enrolled at a public, private, or religious elementary or secondary school. Section 529 plans used to only be allowed for college tuition, up to full tuition amounts. That provision for college tuition remains the same.

The Tax Cuts and Jobs Act modifies Section 529 qualified tuition plans to allow the plans to distribute up to $10,000 in tuition expenses incurred during the tax year for designated beneficiaries enrolled at a public, private, or religious elementary or secondary school. Section 529 plans used to only be allowed for college tuition, up to full tuition amounts. That provision for college tuition remains the same.

Although contributions are not tax deductible for federal tax purposes, funds within a Section 529 plan can accumulate tax-free within the plan until they are distributed tax-free to the educational institution for the child-beneficiary. The new $10,000 limitation applies on a per-student, not per-account basis. As a result, if an individual is a designated beneficiary of multiple accounts, a maximum of $10,000 in distributions will be free of income tax, regardless of whether the funds are distributed from multiple accounts. Some state plans provide a limited deduction against state income taxes for contributions to Section 529 plans. They may also provide caps on contributions.

The expansion of Section 529 plans to cover elementary and secondary school education applies to distributions made after December 31, 2017. Since existing Section 529 set up for a child-beneficiary’s college education may now be redirected earlier to primary and secondary tuition, parents, grandparents and other contributors will need to decide how best to manage each child’s combined accounts: whether amounts needed to cover college tuition should accumulate tax-free until those years, or whether they should be used earlier. Generally, if contributions are limited either by a donor’s financial resources or by state caps, use for college tuition will allow a greater amount to accumulate tax-free. If projected accumulated contributions can cover more than college tuition, then using remaining Section 529 balances for secondary and even elementary school may make sense.

These expanded rules are still young, however, with expected IRS regulations and other guidance overlaid onto the basic law under the Tax Cuts and Jobs Act sure to come. But although the tax-free growth benefits of any Section 529 plans have a long-term perspective, giving some thought to how these expanded Section 529 plans might be used in your family situation might start soon. Please contact our offices for further details.

The IRS expects to receive more than 150 million individual income tax returns this year and issue billions of dollars in refunds. That huge pool of refunds drives scam artists and criminals to steal taxpayer identities and claim fraudulent refunds.

The IRS expects to receive more than 150 million individual income tax returns this year and issue billions of dollars in refunds. That huge pool of refunds drives scam artists and criminals to steal taxpayer identities and claim fraudulent refunds. The IRS has many protections in place to discover false returns and refund claims, but taxpayers still need to be proactive.

Tax-related identity theft

Tax-related identity theft most often occurs when a criminal uses a stolen Social Security number to file a tax return claiming a fraudulent refund. Often, criminals will claim bogus tax credits or deductions to generate large refunds. Fraud is particularly prevalent for the earned income tax credit, residential energy credits and others. In many cases, the victims of tax-related identity theft only discover the crime when they file their genuine return with the IRS. By this time, all the taxpayer can do is to take steps to prevent a recurrence.

Being proactive

However, there are steps taxpayers can take to reduce the likelihood of being a victim of tax-related identity theft. Personal information must be kept confidential. This includes not only an individual's Social Security number (SSN) but other identification materials, such as bank and other financial account numbers, credit and debit card numbers, and medical and insurance information. Paper documents, including old tax returns if they were filed on paper returns, should be kept in a secure location. Documents that are no longer needed should be shredded.

Online information is especially vulnerable and should be protected by using firewalls, anti-spam/virus software, updating security patches and changing passwords frequently. Identity thieves are very skilled at leveraging whatever information they can find online to create a false tax return.

Impersonators

Criminals do not only steal a taxpayer's identity from documents. Telephone tax scams soared during the 2015 filing season. Indeed, a government watchdog reported that this year was a record high for telephone tax scams. These criminals impersonate IRS officials and threaten legal action unless a taxpayer immediately pays a purported tax debt. These criminals sound convincing when they call and use fake names and bogus IRS identification badge numbers. One sure sign of a telephone tax scam is a demand for payment by prepaid debit card. The IRS never demands payment using a prepaid debit card, nor does the IRS ask for credit or debit card numbers over the phone.

The IRS, the Treasury Inspector General for Tax Administration (TIGTA) and the Federal Tax Commission (FTC) are investigating telephone tax fraud. Individuals who have received these types of calls should alert the IRS, TIGTA or the FTC, even if they have not been victimized.

Tax-related identity theft is a time consuming process for victims so the best defense is a good offense. Please contact our office if you have any questions about tax-related identity theft.

An employer must withhold income taxes from compensation paid to common-law employees (but not from compensation paid to independent contractors). The amount withheld from an employee's wages is determined in part by the number of withholding exemptions and allowances the employee claims. Note that although the Tax Code and regulations distinguish between withholding exemptions and withholding allowances, the terms are interchangeable. The amount of reduction attributable to one withholding allowance is the same as that attributable to one withholding exemption. Form W-4 and most informal IRS publications refer to both as withholding allowances, probably to avoid confusion with the complete exemption from withholding for employees with no tax liability.

An employer must withhold income taxes from compensation paid to common-law employees (but not from compensation paid to independent contractors). The amount withheld from an employee's wages is determined in part by the number of withholding exemptions and allowances the employee claims. Note that although the Tax Code and regulations distinguish between "withholding exemptions" and "withholding allowances," the terms are interchangeable. The amount of reduction attributable to one withholding allowance is the same as that attributable to one withholding exemption. Form W-4 and most informal IRS publications refer to both as withholding allowances, probably to avoid confusion with the complete exemption from withholding for employees with no tax liability.

An employee may change the number of withholding exemptions and/or allowances she claims on Form W-4, Employee's Withholding Allowance Certificate. It is generally advisable for an employee to change his or her withholding so that it matches his or her projected federal tax liability as closely as possible. If an employer overwithholds through Form W-4 instructions, then the employee has essentially provided the IRS with an interest-free loan. If, on the other hand, the employer underwithholds, the employee could be liable for a large income tax bill at the end of the year, as well as interest and potential penalties.

How allowances affect withholding

For each exemption or allowance claimed, an amount equal to one personal exemption, prorated to the payroll period, is subtracted from the total amount of wages paid. This reduced amount, rather than the total wage amount, is subject to withholding. In other words, the personal exemption amount is $4,000 for 2015, meaning the prorated exemption amount for an employee receiving a biweekly paycheck is $153.85 ($4,000 divided by 26 paychecks per year) for 2015.

In addition, if an employee's expected income when offset by deductions and credits is low enough so that the employee will not have any income tax liability for the year, the employee may be able to claim a complete exemption from withholding.

Changing the amount withheld

Taxpayers may change the number of withholding allowances they claim based on their estimated and anticipated deductions, credits, and losses for the year.  For example, an employee who anticipates claiming a large number of itemized deductions and tax credits may wish to claim additional withholding allowances if the current number of withholding exemptions he is currently claiming for the year is too low and would result in overwithholding.

Withholding allowances are claimed on Form W-4, Employee's Withholding Allowance Certificate, with the withholding exemptions. An employer should have a Form W-4 on file for each employee. New employees generally must complete Form W-4 for their employer. Existing employees may update that Form W-4 at any time during the year, and should be encouraged to do so as early as possible in 2015 if they either owed significant taxes or received a large refund when filing their 2014 tax return.

The IRS provides an IRS Withholding Calculator at www.irs.gov/individuals that can help individuals to determine how many withholding allowances to claim on their Forms-W-4. In the alternative, employees can use the worksheets and tables that accompany the Form W-4 to compute the appropriate number of allowances.

Employers should note that a Form W-4 remains in effect until an employee provides a new one. If an employee does update her Form W-4, the employer should not adjust withholding for pay periods before the effective date of the new form. If an employee provides the employer with a Form W-4 that replaces an existing Form W-4, the employer should begin to withhold in accordance with the new Form W-4 no later than the start of the first payroll period ending on or after the 30th day from the date on which the employer received the replacement Form W-4.

Estimated tax is used to pay tax on income that is not subject to withholding or if not enough tax is being withheld from a person's salary, pension or other income. Income not subject to withholding can include dividends, capital gains, prizes, awards, interest, self-employment income, and alimony, among other income items. Generally, individuals who do not pay at least 90 percent of their tax through withholding must estimate their income tax liability and make equal quarterly payments of the "required annual payment" liability during the year.

Basic rules

The "basic" rules governing estimated tax payments are not always synonymous with "straightforward" rules. The following addresses some basic rules regarding estimated tax payments by corporations and individuals:

Corporations. For calendar-year corporations, estimated tax installments are due on April 15, June 15, September 15, and December 15. If any due date falls on a Saturday, Sunday or legal holiday, the payment is due on the first following business day. To avoid a penalty, each installment must equal at least 25 percent of the lesser of:

• 100 percent of the tax shown on the corporation's current year's tax return (or of the actual tax, if no return is filed); or
• 100 percent of the tax shown on the corporation's return for the preceding tax year, provided a positive tax liability was shown and the preceding tax year consisted of 12 months.

A lower installment amount may be paid if it is shown that use of an annualized income method, or for corporations with seasonal incomes, an adjusted seasonal method, would result in a lower required installment.

Individuals. For individuals (including sole proprietors, partners, self-employeds, and/or S corporation shareholders who expect to owe tax of more than $1,000), quarterly estimated tax payments are due on April 15, June 15, September 15, and January 15. Individuals who do not pay at least 90 percent of their tax through withholding generally are required to estimate their income tax liability and make equal quarterly payments of the "required annual payment" liability during the year. The required annual payment is generally the lesser of:

• 90 percent of the tax ultimately shown on your return for the 2015 tax year, or 90 percent of the tax due for the year if no return is filed;
• 100 percent of the tax shown on your return for the preceding (2014) tax year if that year was not for a short period of less than 12 months; or
• The annualized income installment.

For higher-income taxpayers whose adjusted gross income (AGI) shown on your 2014 tax return exceeds $150,000 (or $75,000 for a married individual filing separately in 2015), the required annual payment is the lesser of 90 percent of the tax for the current year, or 110 percent of the tax shown on the return for the preceding tax year.

Adjusting estimated tax payments

If you expect an uneven income stream for 2015, your required estimated tax payments may not necessarily be the same for each remaining period, requiring adjustment. The need for, and the extent of, adjustments to your estimated tax payments should be assessed at the end of each installment payment period.

For example, a change in your or your business's income, deductions, credits, and exemptions may make it necessary to refigure estimated tax payments for the remainder of the year. Likewise for individuals, changes in your exemptions, deductions, and credits may require a change in estimated tax payments. To avoid either a penalty from the IRS or overpaying the IRS interest-free, you may want to increase or decrease the amount of your remaining estimated tax payments.

Refiguring tax payments due

There are some general steps you can take to reconfigure your estimated tax payments. To change your estimated tax payments, refigure your total estimated tax payments due. Then, figure the payment due for each remaining payment period. However, be careful: if an estimated tax payment for a previous period is less than one-fourth of your amended estimated tax, you may be subject to a penalty when you file your return.

The tax rules surrounding the dependency exemption deduction on a federal income tax return can be complicated, with many requirements involving who qualifies for the deduction and who qualifies to take the deduction. The deduction can be a very beneficial tax break for taxpayers who qualify to claim dependent children or other qualifying dependent family members on their return. Therefore, it is important to understand the nuances of claiming dependents on your tax return, as the April 18 tax filing deadline is just around the corner.

The deduction can be a very beneficial tax break for taxpayers who qualify to claim dependent children or other qualifying dependent family members on their return. Therefore, it is important to understand the nuances of claiming dependents on your tax return, as the April 18 tax filing deadline is just around the corner.

Dependency deduction

You are allowed one dependency exemption deduction for each person you claim as a qualifying dependent on your federal income tax return. The deduction amount for the 2010 tax year is $3,650. If someone else may claim you as a dependent on their return, however, then you cannot claim a personal exemption (also $3,650) for yourself on your return. Additionally, your standard deduction will be limited.

Only one taxpayer may claim the dependency exemption per qualifying dependent in a tax year. Therefore, you and your spouse (or former spouse in a divorce situation) cannot both claim an exemption for the same dependent, such as your son or daughter, when you are filing separate returns.

Who qualifies as a dependent?

The term "dependent" includes a qualifying child or a qualifying relative. There are a number of tests to determine who qualifies as a dependent child or relative, and who may claim the deduction. These include age, relationship, residency, return filing status, and financial support tests.

The rules regarding who is a qualifying child (not a qualifying relative, which is discussed below), and for whom you may claim a dependency deduction on your 2010 return, generally are as follows:

-- The child is a U.S. citizen, or national, or a resident of the U.S., Canada, or Mexico;

-- The child is your child (including adopted or step-children), grandchildren, great-grandchildren, brothers, sisters (including step-brothers, and -sisters), half-siblings, nieces, and nephews;

 -- The child has lived with you a majority of nights during the year, whether or not he or she is related to you;

 -- The child receives less than $3,650 of gross income (unless the dependent is your child and either (1) is under age 19, (2) is a full-time student under age 24 before the end of the year), or (3) any age if permanently and totally disabled;

 -- The child receives more than one-half of his or her support from you; and

 -- The child does not file a joint tax return (unless solely to obtain a tax refund).

Qualifying relatives

The rules for claiming a qualifying relative as a dependent on your income tax return are slightly different from the rules for claiming a dependent child. Certain tests must also be met, including a gross income and support test, and a relationship test, among others. Generally, to claim a "qualifying relative" as your dependent:

-- The individual cannot be your qualifying child or the qualifying child of any other taxpayer; -- The individual's gross income for the year is less than $3,650; -- You provide more than one-half of the individual's total support for the year; -- The individual either (1) lives with you all year as a member of your household or (2) does not live with you but is your brother or sister (include step and half-siblings), mother or father, grandparent or other direct ancestor, stepparent, niece, nephew, aunt, or uncle, or inlaws. Foster parents are excluded.

Although age is a factor when claiming a qualifying child, a qualifying relative can be any age.

Special rules for divorced and separated parents

Certain rules apply when parents are divorced or separated and want to claim the dependency exemption. Under these rules, generally the "custodial" parent may claim the dependency deduction. The custodial parent is generally the parent with whom the child resides for the greater number of nights during the year.

However, if certain conditions are met, the noncustodial parent may claim the dependency exemption. The noncustodial parent can generally claim the deduction if:

-- The custodial parent gives up the tax deduction by signing a written release (on Form 8332 or a similar statement) that he or she will not claim the child as a dependent on his or her tax return. The noncustodial parent must attach the statement to his or her tax return; or

-- There is a multiple support agreement (Form 2120, Multiple Support Declaration) in effect signed by the other parent agreeing not to claim the dependency deduction for the year.
