This chapter prescribes procedures for withholding, depositing, reporting, and paying taxes as follows:

Section 4010—Scope and Applicability

Employers must withhold income taxes and the employee's portion of Social Security and Medicare taxes and pay the employer's portion of Social Security and Medicare taxes on wages paid to an employee. (See also TFM subsection 4020.30.)

For further instructions and/or guidance on these matters:

Section 4015—Authority

Procedures in this chapter are authorized by provisions in the Internal Revenue Code (the IRC) [Title 26 of the United States Code (U.S.C.)] regarding Federal income tax withholding, and Social Security and Medicare taxes under FICA. Services performed in the employ of the United States are excepted from the tax imposed under the Federal Unemployment Tax Act (FUTA) [IRC section 3306(c)(6)].

The Department of the Treasury (Treasury) has the authority to determine [IRC section 3122]:

All employers, including Federal agencies, must deduct and withhold Federal income taxes from wages that exceed the total amount of withholding exemptions [IRC section 3402(a)]. If the employer is the United States or any agency or instrumentality of the United States, any officer or employee of the United States having control of the payment of wages or an appropriate designee may file the tax return for the amount deducted and withheld from wages [IRC section 3404].

Section 4020—Federal Withholding Rules

4020.10—Specific Rules

IRC section 3101 imposes the employee's portion of Social Security and Medicare taxes on wages paid to the employee. IRC section 3102 requires the employer to withhold these amounts from wages paid to employees.

IRC section 3111 imposes the employer's portion of the Social Security and Medicare taxes on wages paid to employees.

4020.20—Federal Income, Social Security, and Medicare Deposits

Most large agencies must make their tax deposits electronically [IRC section 6302(h)]. Employer agencies send withheld Federal income, Social Security, and Medicare taxes to the IRS through the FEDTAX II system. Those agencies not established on the FEDTAX II system must contact FEDTAX II customer service or the Financial Services Division, Financial Management Service (FMS). See the Contacts page for the telephone numbers.

Users may obtain the FEDTAX II User Profile Sheet and the Application for FEDTAX II Form 941 PIN Code on the FEDTAX II Web site at http://www.fms.treas.gov/fedtax/forms.html.

If FEDTAX II is unavailable because a commercial financial institution rather than Treasury disburses the funds, agencies use the Electronic Federal Tax Payment System (EFTPS). See Circular E for instructions on enrolling in EFTPS.

4020.30—Federal Income, Social Security, and Medicare Taxes Regarding Employee or Independent Contractor

Generally, an employer must withhold income taxes and pay Social Security and Medicare taxes on wages paid to an employee. Employers do not have to withhold or pay any taxes on payments to an independent contractor. There is, however, a requirement to issue information returns for payments of $600 or more in a calendar year to independent contractors. See Appendix 1, Guide to Information Returns, Form 1099-MISC.

4020.40—Employee/Independent Contractor Status

To determine a worker's status as an employee or an independent contractor, apply the common law rule:

An employer-employee relationship exists when the person for whom the services are performed has the right to control and direct the individual who performs the services.

This control refers not only to the result to be accomplished but also to the means and details by which that result is accomplished. An employee is subject to the will and control of the employer not only as to what work must be done, but, also, as to how it will be done. It is not necessary that the employer actually direct or control the manner in which the services are performed; it is sufficient that the employer has the right to do so.

Employee status is determined by the presence of the employer's right to control. The sum of all the facts and circumstances always determines whether this right exists. See IRS Publication 15-A for more information.

Employers that want the IRS to decide if a worker is an employee should submit Form SS-8: Determination of Worker Status for Purposes of Federal Employment Taxes and Income Tax Withholding, to the IRS office listed on the Contacts page.

Section 4025—IRC Instructions

4025.10—Withholding and Deducting Federal Income Tax

Employers, including Federal agencies, must deduct and withhold Federal income taxes from wages [IRC sections 3402(a) and 3404].

4025.20—Withholding Additional Income Tax

Employers may withhold additional amounts of Federal income tax by agreement between the employer and the employee [Employment Tax Regulation Section 31.3402(i)-1(a)]. The employee may claim fewer exemptions or may have an additional fixed amount withheld each pay period.

4025.30—Additional Withholding Allowance

Employees may claim additional withholding allowances based on estimated itemized deductions and credits [IRC section 3402(m)]. Form W-4: Employee's Withholding Allowance Certificate, provides a schedule and instructions for determining total withholding allowances.

4025.40—Withholding Not Required

Employers should not deduct and withhold Federal income tax from employee wages when the employee certifies (as prescribed by IRS) that no income tax liability was incurred the preceding year nor is one anticipated for the current year [IRC section 3402(n)].

4025.50—Rounding Amounts of Federal Income Tax Withheld

Employers may round to the nearest dollar the tax withheld from each employee. Rounding eliminates amounts less than 50 cents and increases amounts greater than 50 cents to the next higher dollar.

4025.60—Submission Requirements for Form W-4 (Revised by I TFM Bulletin No. 2005-05)

In the past, employers had to routinely send the IRS any Form W-4 claiming more than 10 allowances or claiming complete exemption from withholding if $200 or more in weekly wages was expected. Employers no longer have to submit these Forms W-4 to the IRS. However, Forms W-4 are still subject to review. Employers may be directed (in a written notice or in future published guidance) to send certain Forms W-4 to the IRS.

The IRS also will use information reported on Forms W-2: Wage and Tax Statement, to more effectively identify employees with withholding compliance problems. In some cases, where a serious under-withholding problem is found to exist for a particular employee, the IRS may issue a notice (commonly referred to as a "lock-in letter") to the employer specifying the maximum number of withholding allowances permitted for a specific employee. After the IRS issues a lock-in letter, if the employee wants to claim complete exemption from withholding or to claim a number of withholding allowances more than the maximum number specified by the IRS in the lock-in letter, the employee must submit a new Form W-4 and a written statement to support the claims made by the employee on the Form W-4 to the IRS. The employer must disregard this new Form W-4 until the IRS notifies the employer to withhold tax based on the new Form W-4. However, if, at any time, the employee furnishes a Form W-4 that claims a number of withholding allowances less than the maximum number specified in the lock-in letter, the employer must withhold tax based on that Form W-4.

4025.70—Expiration of Form W4

Employees must submit new Forms W-4 by February 15 if they claim exemption from withholding. If an employee does not do so, the employer must withhold taxes as though the employee was single, claiming zero exemptions.

4025.80—Invalid W-4

Any unauthorized change or addition to Form W-4 makes it invalid. This includes taking out any language by which the employee certifies that the form is correct. A Form W-4 also is invalid if, by the date an employee submits it, he or she indicates in any way that it is false. An employee who files a false Form W-4 may be subject to a $500 penalty.

An agency must not use an invalid Form W-4 to figure withholding. It must tell the employee that the Form W-4 is invalid and ask for another one. If the employee does not submit a valid Form W-4, the agency withholds taxes as if the employee is single and claiming no withholding allowances. However, if the agency has an earlier Form W-4 for this employee that is valid, the agency withholds as it did before.

Section 4030—Federal Insurance Contributions Act (FICA)

Employers must deduct and withhold the employee's portion of FICA taxes from wages paid to employees [IRC section 3102]. Employers must pay the employer's portion of the FICA tax [IRC sections 3111 and 3112]. FICA taxes consist of two different taxes:

4030.10—Civilian Employees Hired before January 1, 1984

Civilian employees hired before January 1, 1984, and covered under the Civil Service Retirement System (CSRS) are not subject to the Social Security tax. These employees are only subject to the Medicare tax [IRC sections 3121(b)(5) and 3121(u)(1)].

4030.20—Employees Subject to Social Security and Medicare Taxes

Both Social Security and Medicare taxes are imposed on the following groups:

4030.30—Employees Not Covered for Social Security and Medicare Under the IRC

The following employees are not covered for Social Security and Medicare under the IRC:

Section 4035—Correcting Income and FICA Tax Withholding Errors

An agency should correct errors in withholding income taxes made in a prior pay period of the current calendar year if the employee is still on the agency's payroll. Employer agencies:

If an agency makes an adjustment or applies for a refund of FICA and Medicare taxes overcollected from an employee, the agency must repay the employee's portion to the employee. Obtain from the employee a written receipt showing the date and amount of the repayment and a written statement that the employee will not claim a refund or credit for the amount.

Generally, an agency may make an adjustment or claim for refund only within 3 years of the due date of the return or the date the return was filed, whichever is later. For statute of limitations purposes, the filing date for Forms 941 is April 15 of the year after the calendar year for which the forms were filed. For example, the four quarterly Forms 941 for 1998 are all treated as filed on April 15, 1999, provided they were filed timely. If 1998 Forms 941 were filed on or before April 15, 1999, agencies may make adjustments for any of the quarterly returns until April 15, 2002.

FEDTAX II Form 941 filers should send the Form 941c by fax to the IRS Memphis Service Center. Refer to Circular E and the FEDTAX II User Guide for further instructions. User's may request a copy of the FEDTAX II User Guide by calling 1-877-333-8292 (toll free).

Section 4040—Privacy Act Requirements

Each agency must publish notices for routine use in the Federal Register in accordance with the Privacy Act of 1974. These notices must indicate information routinely disclosed by the agency to IRS and SSA and the circumstances under which disclosure is made.

If Federal forms used by the agency do not include a Privacy Act notice, the agency must provide a separate Privacy Act notice to the employee from whom information is solicited. A suggested notice follows:

The Social Security number is required for identification purposes by Executive Order 9397, dated November 22, 1943. Other information is required under 26 U.S.C. section 3401-04 for collecting taxes at the source by withholding from wages. The information is used to compute the amount withheld, and, if not furnished, a violation of the Internal Revenue laws may occur.

Section 4045—Accounting for Taxes

4045.10—Withheld Taxes

Agencies must report separately on FEDTAX II or EFTPS Federal income, Social Security, and Medicare taxes withheld from employees' wages.

SSA records these amounts separately in employees' permanent earnings records.

4045.20—Employer's Social Security and Medicare Tax

Each agency employing individuals covered by Social Security and Medicare tax must pay the employer's share of these taxes on the employees' salaries and wages. These taxes are disbursed each pay period from the appropriation from which the payroll is paid. They are deposited with the taxes withheld from employees' compensation.

Section 4050—Payment of Taxes

4050.10—Electronic Payment of Taxes

Agencies whose funds are disbursed by Treasury should use FEDTAX II; agencies whose funds are disbursed from a commercial financial institution should use EFTPS.

4050.20—Deadlines for Deposits

Agencies must submit tax deposits in time to ensure credit to the Treasury's General Account by the tax due date. Agencies that make payments using FEDTAX II must transmit the payments no later than the payment due date. Agencies that make payments using EFTPS generally must initiate payments the day before the due date, to settle on the due date.

4050.30—Taxes Withheld From Supplemental Wage Payments

Agencies must compute Federal income taxes withheld from wages other than regular salary payments following instructions in Circular E, section 7. Examples of this type of wage include the following:

Agencies must deposit the amount withheld in the same manner as other withheld taxes.

4050.40—Back Pay

Back pay is pay received in one period for employment (or potential employment) in an earlier period. Back pay is treated as wages in the year received. FICA tax and income tax withholding apply in the year of payment using the rates and the wage base in effect for that period. Back pay does not include amounts specifically and legitimately designated otherwise, for example, interest, penalties, and legal fees.

If the agency did not include back pay as wages on a previously filed Form W-2: Wage and Tax Statement, the agency should prepare a wage correction report, on Form W-2c or magnetic media, to add the back pay award to the wages of that employee.

For income tax purposes, the IRS treats back pay as wages in the year paid. The SSA, however, credits back pay awarded under a statute to the year(s) when it should have been paid. The agency must notify SSA of the payment so that SSA can allocate the back pay to the appropriate periods. If the agency paid the back pay in the tax year in which it was earned, it should report the wages on that year's Form W-2. No further action is necessary.

For further information, see SSA Publication 957, Reporting Back Pay and Special Wage Payments to the Social Security Administration.

Section 4055—Filing Quarterly Tax Returns

Agencies file quarterly tax returns with IRS on Form 941. If an agency uses FEDTAX II to submit the payment, FEDTAX II generates a Form 941 for review and approval. The agency then transmits Form 941 electronically to IRS.

If agencies do not use FEDTAX II, those within the United States mail their tax returns to the IRS Service Center serving the State in which the agency office is located (see Circular E). Agencies outside the United States mail their tax returns to the Philadelphia Service Center.

Agencies' tax returns are due by the end of the month following the close of the quarter. However, if all deposits were made timely during the quarter, then the agency has an additional 10 days to file. The Philadelphia Service Center processes foreign and military APO/FPO tax returns.

Agencies enter tax payment information under Schedule B, Employer's Record of Federal Tax Liability, on Form 941 from the agencies' record of payment. The total amount of the tax payments made during the quarter should equal the total taxes due, with no further payment required with the tax return. For FEDTAX II filers, Schedule B is automatically generated from the liability information entered with the payments during the quarter.

Section 4060—Filing Annual Information Returns

This section applies to departments and agencies required to file annual information returns with SSA, covering salaries and wages, or with the IRS, covering other types of transactions subject to information reporting.

Keep records for at least 4 years and have them available for IRS review. Records should include:

4060.10—Guide to Information Returns

Information returns include the Form W-2 series, Form 1099 series, and Form 1098: Mortgage Interest Statement. Appendix 1, Guide to Information Returns, lists these forms. For additional information, see General Instructions for Forms 1099, 1098, 5498, and W-2G.

4060.20—Instructions for Filing Information Returns

IRS publications Instructions 1099 and Package 1099 contain instructions for filing transmittal Form 1096 and Form 1099 series information returns, including Forms 1098, 1099, 5498, and W-2G. For technical specifications on magnetic media filing, refer to IRS' Revenue Procedure issued annually.

4060.30—Filing Form W-2 Series Information Returns

Refer to Circular E for information regarding classification of employees and for specific filing instructions.

Reconcile the Forms 941 with wages reported on Forms W-2. Reconcile Form W-3: Transmittal of Wage and Tax Statements, with totals reported on Form 941.

Annually, use the Form W-2 series to report salaries, wages, and other payments to employees to IRS. In addition, agencies use Form W-3 to report Form W-2s to SSA annually.

4060.40—Filing Form 1099-C: Cancellation of Debt, and Form 1098 Information Returns

Employer Identification Number (EIN)

Forms 1098 and 1099 must show both a payer and a payee identification number. The agency must use the EIN assigned to it by IRS. The agency's name must agree with the name used on other returns (such as Form 941) filed using this EIN. The taxpayer's identification number is the Social Security number for individuals (including operators of businesses as sole proprietorships) or the EIN for other entities.

Filing Form 1099-C Information Returns

An agency files a Form 1099-C for each debtor for whom the agency canceled a debt of $600 or more. In addition, the agency files a Form 1099-C when an identifiable event has occurred, such as the bankruptcy discharge of the debtor.

An agency must report the forgiveness of debt regardless of whether the debtor is eligible to exclude the debt from income because of the debtor's insolvency, bankruptcy, or other reason. For further information on the reporting requirements, see the General Instructions for Forms 1099, 1098, 5498, and W-2G. An agency should not report a debt as forgiven if the agency is attempting to collect the debt.

An agency participating in the Federal tax refund offset program or any other Federal debt collection mechanism should not report the debt as forgiven.

Filing Form 1098 Information Returns

Agencies use Form 1098 to report mortgage interest received from individuals. The agency that receives the mortgage interest reports to the IRS and the payer. See Appendix 1 for filing requirements.

Annual Reporting of Form 1099 Series and Form 1098 Information Returns

Annually, agencies transmit Forms 1098 and 1099 to the IRS by February 28 of the year following the year for which the returns are filed. For instance, tax year 2001 returns are due on February 28, 2002. If forms are filed electronically (not by magnetic media), the due date is March 31. Statements to the payee are due by January 31. Prepare Form 1096: Annual Summary and Transmittal of U.S. Information Returns, to accompany the Forms 1098 and 1099 as a transmittal document. Prepare a separate Form 1096 for each type of document transmitted. For example, if filing Forms 1099-MISC and 1099-G, group the 1099s by type and use a separate Form 1096 as a transmittal for each group.

4060.50 — Other Reporting Requirements and Reporting Thresholds

Report payments for services totaling $600 or more to individuals, partnerships, and trusts. Executive agencies, military departments, the Postal Service, and the Postal Rate Commission also must report payments to corporations for services totaling $600 or more. Federal agencies acting as financial institutions must report interest payments of $10 or more.

Form 945: Annual Return of Withheld Federal Income Tax

Agencies must secure a payee's Taxpayer Identification Number (TIN) before issuing payments. Backup withholding is required if the payee does not furnish a TIN. Report backup withholding on Form 945, along with withholding on pensions and annuities. Deposit requirements for Form 945 are the same as for Form 941. Prepare and mail Form 945 to the local IRS Service Center by January 31 of the year following the withholding. If, however, all deposits were made timely during the year, then the agency has an additional 10 days to file.

Section 4065—Use of Magnetic Media for Filing Annual Information Returns

This section applies to all departments and agencies that file annual information returns. See TFM Section 4060.

4065.10—Magnetic Media Reporting of Form W-2 to SSA

All agencies represented by an EIN must furnish annual information returns on magnetic media for the Form W-2 series to SSA as prescribed by SSA's magnetic media specifications. For specific instructions on filing magnetic media and filing electronically, see SSA's MMREF-1 publication, Magnetic Media Reporting and Electronic Filing. This publication is available on SSA's employer reporting instructions and information Web site at www.socialsecurity.gov/employer/pub.htm.

4065.20—Magnetic Media Reporting of Form 1099 to IRS

All agencies must furnish annual information returns for the Form 1099 series to IRS.

If an agency files 250 or more information returns, it must file on magnetic media. The 250-or-more requirement applies separately to each type of form. See IRS Publication 1220, Specifications for Filing Forms 1098, 1099, 5498 and W-2G Electronically or Magnetically, or General Instructions for Forms 1099, 1098, 5498, and W-2G.

4065.30—Installation of a New or Updated Magnetic Media System

When an agency installs or updates a system with magnetic media reporting capability, the agency must comply with the requirements in system design and programming discussed in the previous subsections.

4065.40—Partial Use of a Computerized System

An agency does not have to operate with a computerized system for its entire output under that EIN to be subject to the magnetic media reporting requirements.

For example, SSA accepts the paper Form W-2 series for the noncomputerized portion of a payroll operation and magnetic media records for the computerized portion. IRS, likewise, accepts the paper Form 1099 series for the noncomputerized portion of a disbursement operation and magnetic media records for the computerized portion. Up to 250 Forms W-2 may be filed on paper without penalty. However, the IRS may waive the magnetic media filing requirement if an agency can show hardship.

4065.50—Use of Another Agency's Computer System

If the payroll or other disbursement operation of an agency is serviced, in whole or in part, through another agency's computer system, the servicing agency must comply with the requirements of this section. However, the EIN being reported is that of the agency authorizing payment.

Section 4070—Resident and Nonresident Aliens

In general, taxation varies for resident and nonresident aliens and could be subject to treaty provisions.

4070.10—Withholding Federal Income Tax

Generally, for wages paid to both resident aliens and nonresident aliens for services rendered in the United States as employees, agencies withhold Federal income tax according to the same rules, procedures, and rates applicable to employees who are U.S. citizens.

4070.20—Withholding Exemptions

Resident aliens may claim the full number of withholding exemptions they would be entitled to under the rules applicable to U.S. citizens. Nonresident aliens who are residents of Canada, Mexico, Japan, or South Korea also may claim the full number of withholding exemptions they would be entitled to under the rules applicable to U.S. citizens. All other nonresident aliens may claim only one withholding exemption.

4070.30—Social Security and Medicare Taxes

Nonresident aliens in the United States on “F-1,” “J-1,” or “M-1” visas do not pay Social Security and Medicare taxes on money earned while performing services for which such visas were granted. This income is not subject to Social Security and Medicare taxes even if it is for services not covered by the U.S. Government retirement system.

Compensation for services performed in and for the United States by other nonresident and resident aliens is subject to Social Security and Medicare taxes if such service is not covered by a retirement system established by the United States. Remuneration paid to resident aliens is subject to Social Security and Medicare taxes, whether the services are performed outside or in the United States. Remuneration paid to nonresident aliens for services outside the United States is not subject to Social Security and Medicare taxes. Report withholding on payments to nonresident aliens on Form 1042: Annual Withholding Tax Return for U.S. Source Income of Foreign Persons, and deposit the withholdings according to the same rules as Form 941.

4070.40—Payment of Taxes and Tax Returns

Handle withheld Federal income, Social Security, and Medicare taxes on wages paid to resident and nonresident aliens covered under this section in the manner prescribed in TFM Sections 4045, 4050, 4055, and 4060. Include these taxes in the total tax payment for withheld Federal income, Social Security, and Medicare taxes transmitted on FEDTAX II or EFTPS and reported on Form 941.

4070.50—Overseas Taxpayer Service Locations

See Appendix 2 for a directory of IRS representatives in foreign countries.

Section 4075—Deceased Employees

If an employer pays a deceased employee's unpaid salary and wages and unused annual leave to the deceased employee's beneficiary or estate in the calendar year in which the employee died, these amounts are subject to Social Security and Medicare taxes. The employer deducts and withholds Social Security and Medicare taxes from the unpaid current compensation and the payment for unused annual leave.

Handle the amount withheld and the employer's contributions as prescribed in TFM Sections 4045, 4050, 4055, and 4060. Wages paid to a beneficiary or the employee's estate after the calendar year in which the employee died are not subject to FICA taxes. [See IRC section 3121(a)(14); Rev. Rul. 86-109, 1986-2 C.B. 196.]

According to Rev. Rul. 86-109, report the accrued wages and vacation pay of a deceased employee paid to an estate, or other person who has acquired the right to receive the payments, on Form 1099-MISC.

Do not treat these payments as wages for purposes of collecting income taxes at the source. Therefore, do not include these payments in Box 1, Wages, tips, other compensation, of the final Form W-2. Treat these payments as wages for the purpose of Social Security and Medicare taxes only if paid to the survivor or estate before the close of the calendar year in which the employee died. If they are paid before that date, the amount of the payment appears as Social Security wages (up to the amount of the wage base) and Medicare wages on the final Form W-2. Do not include these payments in Box 1 as wages.

Report the entire amount of death benefits on Form 1099-R. Those benefits may be from a qualified plan paid to an estate or other person who has acquired the right to receive the payments solely because of the death of the employee. Also, report death benefit payments from a nonqualified plan on Form 1099-R.

Section 4080—Levy for Unpaid Tax Liability

The IRS collects delinquent Federal taxes by levy on the accrued salary or wages of any officer, employee, or elected official of the United States or the District of Columbia. Since the levy is served against the take-home pay of the employee, agencies should not permit employees to increase any voluntary allotment after notice of levy has been received until the tax liability is liquidated or other arrangements satisfactory to the IRS are made.

4080.10—Service of Levy

An IRS agent serves notice of levy on wages, salary, and other income of individuals. See TFM subsection 4080.20. The agent serves the notice in person or by mail. Service by mail is limited to the United States, its territories and possessions, and ships at sea. The notice includes the original and four copies. All copies must be signed and dated, and the time of receipt must be entered on the forms. The employer agency returns the original to the IRS agent and keeps one copy. IRS or the employer agency forwards one copy to the employee.

The person designated under TFM subsection 4080.20 honors all applicable notices of levy, whether served in person or received by mail. The Government Accountability Office makes no disallowance nor does it raise charges against any disbursing officer or designated person for complying with notices of levy.

4080.20—Designation of Individuals to Receive Service of Notice of Levy

Each Government agency should designate one or more persons on whom notice of levy for delinquent taxes of the agency's employees may be served. These designees receive written statements from such employees regarding exemptions for dependents as provided for in the IRC.

4080.30—Minimum Exemption from Levy for Wages, Salary, and Other Income

A check to the employee each pay period includes exempt take-home pay and the amount by which the nonexempt take-home pay exceeds the levy amount. Agencies should refer to the IRC for specific exemptions and related procedures, or contact their local IRS office.

4080.40—Continuing Levy on Salary and Wages

The levy on salary or wages starts from the date IRS serves the levy and continues until IRS releases it.

4080.50—Liquidation through Payroll Deductions

An employee may arrange with IRS to liquidate his or her tax liability by payroll deduction. IRS Form 2159: Payroll Deduction Agreement, signed by a revenue officer (or other authorized IRS agent) and by the employee is the authorization for payroll deductions. Send the original to the payroll office. The employer agency deducts from each salary payment the agreed amount until the total tax liability is liquidated.

4080.60—Payment to Internal Revenue Service

The agency makes one payment each pay period to the IRS to cover amounts deducted from employees' pay. Attach a list to the payment containing each employee's name and TIN, the amount, and the taxable year. Send the payment to the address specified by the revenue officer or other authorized IRS agent.

Section 4085—Payment or Reimbursement of Employees' Expenses

An employer may exclude reimbursement of employee business expenses from employees' incomes and should not subject it to Federal income, Social Security, and Medicare tax withholdings only if the employer has a reimbursement or other expense allowance arrangement that is an “accountable plan.” Such a plan must require that the employee substantiate the amounts and business purposes of expenditures and return advances in excess of expenses to the employer. See section 1.62-2 of the Income Tax Regulations for the meaning of an accountable plan.

4085.10—Payments Under an Accountable Plan

An employer may exclude reimbursement of employee business expenses from employees' incomes if it has a reimbursement or other expense allowance arrangement that qualifies as an “accountable plan.” Under an accountable plan, employees must be required to substantiate all business expenses and to return amounts advanced for expenses that are not substantiated within a reasonable period. Payments under an accountable plan can be excluded from FICA and income tax.

If an agency gives an employee a per diem or standard mileage rate for auto expenses, the employee must establish the time, place, and business purpose of the expense. Then, if the reimbursed amount is the same as or less than the Government specified rates, do not include the amount in the employee's income.

The Federal per diem rates are published, by locality, at 41 Code of Federal Regulations, Chapter 301, Appendix A. Each year, the IRS publishes a revenue procedure that provides rules by which business expenses are deemed substantiated under the regulations.

Do not report amounts paid under an accountable plan as income on Form W-2 and do not withhold Federal income, Social Security, and Medicare taxes. Report such amounts in Box 13 of Form W-2 using Code L.

4085.20—Amounts Treated as Paid Under a Nonaccountable Plan

Report as wages on Form W-2 amounts paid to employees for business expenses if any of the following occur:

Report payments under a nonaccountable plan, including unsubstantiated business expenses and unreturned excess amounts, as wages on Form W-2. These amounts are subject to FICA and income tax withholding. Also report to the employee any amount of taxes withheld on unsubstantiated or excess amounts.

4085.30—Payment or Reimbursement of Moving Expenses

Exclude employer's payment or reimbursement of employees' moving expenses from income, and from withholding taxes, only if it is paid under an arrangement similar to an accountable plan, as defined herein.

Exclude moving expense reimbursement from the employee's income, and from withholding taxes, only if it is a qualified moving expense (one that would otherwise be deductible by the employee) [IRC sections 217, 132(g)]. Do not exclude the reimbursement if the employee actually deducted the expense in a prior taxable year.

Report excluded moving expense reimbursements in Box 13 of Form W-2 using Code P. Refer to IRS Circular E or Publication 521, Moving Expense, for additional information.
