Federal Insurance Contributions Act (FICA) of 1935

Reuse Permissions

The Federal Insurance Contributions Act (FICA) provides for a federal system of old-age, survivors, disability, and hospital insurance. The old-age, survivors, and disability insurance part is financed by the social security tax. The hospital insurance part is financed by the Medicare tax. Each of these taxes is reported separately.

Generally, you are required to withhold social security and Medicare taxes from your employees' wages and you must also pay a matching amount of these taxes. Certain types of wages and compensation are not subject to social security and Medicare taxes. See sections 5 and 15 for details. Generally, employee wages are subject to social security and Medicare taxes regardless of the employee's age or whether he or she is receiving social security benefits. If the employee reported tips, see section 6.

Tax rates and the social security wage base limit. Social security and Medicare taxes have different rates and only the social security tax has a wage base limit. The wage base limit is the maximum wage that is subject to the tax for the year. Determine the amount of withholding for social security and Medicare taxes by multiplying each payment by the employee tax rate. There are no withholding allowances for social security and Medicare taxes.

The employee tax rate for social security is 6.2% (amount withheld). The employer tax rate for social security is also 6.2% (12.4% total). The 2006 wage base limit was $94,200. For 2007, the wage base limit is $97,500.

The employee tax rate for Medicare is 1.45% (amount withheld). The employer tax rate for Medicare tax is also 1.45% (2.9% total). There is no wage base limit for Medicare tax; all covered wages are subject to Medicare tax.

Successor employer. If you received all or most of the property used in the trade or business of another employer, or a unit of that employer's trade or business, you may include the wages that the other employer paid to your acquired employees before the transfer of property when you figure the annual wage base limit for social security. You should determine whether or not you should file Schedule D (Form 941), Report of Discrepancies Caused by Acquisitions, Statutory Mergers, or Consolidations, by reviewing the Instructions for Schedule D (Form 941). See Regulations Section 31.3121(a)(1)-1(b) for more information. Also see Rev. Proc. 2004-53 for more information. You can find Rev. Proc. 2004-53 on page 320 of Internal Revenue Bulletin 2004-34 at www.irs.gov/pub/irs-irbs/irb04-34.pdf.

Withholding of social security and Medicare taxes on nonresident aliens. In general, if you pay wages to nonresident alien employees, you must withhold federal social security and Medicare taxes as you would for a U.S. citizen. However, see Publication 515, Withholding of Tax on Nonresident Aliens and Foreign Entities, for exceptions to this general rule.

International social security agreements. The United States has social security agreements with many countries that eliminate dual taxation and dual coverage. Compensation subject to social security and Medicare taxes may be exempt under one of these agreements. You can get more information and a list of agreement countries from SSA at www.socialsecurity.gov/international or see section 7 of Publication 15-A, Employer's Supplemental Tax Guide.

Religious exemption. An exemption from social security and Medicare taxes is available to members of a recognized religious sect opposed to insurance. This exemption is available only if both the employee and the employer are members of the sect.

Part-Time Workers

For federal income tax withholding and social security, Medicare, and federal unemployment (FUTA) tax purposes, there are no differences among full-time employees, part-time employees, and employees hired for short periods. It does not matter whether the worker has another job or has the maximum amount of social security tax withheld by another employer. Income tax withholding may be figured the same way as for full-time workers. Or it may be figured by the part-year employment method explained in section 9 of Publication 15-A.

10. Advance Earned Income Credit (EIC) Payment

An employee who expects to be eligible for the earned income credit (EIC) and expects to have a qualifying child is entitled to receive EIC payments with his or her pay during the year. To get these payments, the employee must provide to you a properly completed Form W-5 (or Forma W-5(SP), its Spanish translation), Earned Income Credit Advance Payment Certificate, using either the paper form or an approved electronic format. You are required to make advance EIC payments to employees who give you a completed and signed Form W-5. You may establish a system to electronically receive Forms W-5 from your employees. See Announcement 99-3 for information on electronic requirements for Form W-5. You can find Announcement 99-3 on page 15 of Internal Revenue Bulletin 1999-3 at www.irs.gov/pub/irs-irbs/irb99-03.pdf.

Certain employees who do not have a qualifying child may be able to claim the EIC on their tax return. However, they cannot get advance EIC payments.

Form W-5. Form W-5 explains the eligibility requirements for receiving advance EIC payments. On Form W-5, an employee states that he or she expects to be eligible to claim the EIC and shows whether he or she has another Form W-5 in effect with any other current employer. The employee also shows the following:

  • Whether he or she expects to have a qualifying child.
  • Whether he or she will file a joint return.
  • If the employee is married, whether his or her spouse has a Form W-5 in effect with any employer.

An employee may have only one certificate in effect with a current employer at one time. If an employee is married and his or her spouse also works, each spouse should file a separate Form W-5.

Length of effective period. Form W-5 is effective for the first payroll period ending on or after the date the employee gives you the form (or the first wage payment made without regard to a payroll period). It remains in effect until the end of the calendar year unless the employee revokes it or files another one. Eligible employees must file a new Form W-5 each year.

Change of status. If an employee gives you a signed Form W-5 and later becomes ineligible for advance EIC payments, he or she must revoke Form W-5 within 10 days after learning about the change of circumstances. The employee must give you a new Form W-5 stating that he or she is no longer eligible for or no longer wants advance EIC payments.

If an employee's situation changes because his or her spouse files a Form W-5, the employee must file a new Form W-5 showing that his or her spouse has a Form W-5 in effect with an employer. This will reduce the maximum amount of advance payments that you can make to that employee.

If an employee's spouse has filed a Form W-5 that is no longer in effect, the employee may file a new Form W-5 with you, but is not required to do so. A new form will certify that the spouse does not have a Form W-5 in effect and will increase the maximum amount of advance payments you can make to that employee.

Invalid Form W-5. The Form W-5 is invalid if it is incomplete, unsigned, or has an alteration or unauthorized addition. The form has been altered if any of the language has been deleted. Any writing added to the form other than the requested entries is an unauthorized addition.

You should consider a Form W-5 invalid if an employee has made an oral or written statement that clearly shows the Form W-5 to be false. If you receive an invalid form, tell the employee that it is invalid as of the date that he or she made the oral or written statement. For advance EIC payment purposes, the invalid Form W-5 is considered void.

You are not required to determine if a completed and signed Form W-5 is correct. However, you should contact the IRS if you have reason to believe that it contains an incorrect statement.

How to figure the advance EIC payment. To figure the amount of the advance EIC payment to include with the employee's pay, you must consider:

  • Wages, including reported tips, for the same period. Generally, figure advance EIC payments using the amount of wages subject to income tax withholding. If an employee's wages are not subject to income tax withholding, use the amount of wages subject to withholding for social security and Medicare taxes.
  • Whether the employee is married or single.
  • Whether a married employee's spouse has a Form W-5 in effect with an employer.

Do not consider combat zone pay received by the employee and excluded from income as earned income when figuring the advance EIC payment.

Figure the amount of advance EIC to include in the employee's pay by using the tables that begin on page 59. There are separate tables for employees whose spouses have a Form W-5 in effect. See page 35 for instructions on using the advance EIC payment tables.

The amount of advance EIC paid to an employee during 2007 cannot exceed $1,712. If during the year you have paid an employee total wages of at least $33,241 ($35,241 if married filing jointly), you must also stop making advance EIC payments to that employee for the rest of the year.

Paying the advance EIC to employees. An advance EIC payment is not subject to withholding of income, social security, or Medicare taxes. An advance EIC payment does not change the amount of income, social security, or Medicare taxes that you withhold from the employee's wages. You add the EIC payment to the employee's net pay for the pay period. At the end of the year, you show the total advance EIC payments in box 9 on Form W-2. Do not include this amount as wages in box 1.

Employer's returns. Show the total payments that you made to employees on the advance EIC payments line (line 9) of your Form 941 (line 8 of Form 944). Subtract this amount from your total taxes on line 8 (line 7 of Form 944). See the separate Instructions for Form 941 (or the separate Instructions for Form 944). Reduce the amounts reported on line 15 of Form 941 or on appropriate lines of Schedule B (Form 941), Report of Tax Liability for Semiweekly Schedule Depositors, by any advance EIC paid to your employees.

Generally, employers will make the advance EIC payment from withheld income tax and employee and employer social security and Medicare taxes. These taxes are normally required to be paid over to the IRS either through federal tax deposits or with employment tax returns. For purposes of deposit due dates, advance EIC payments are treated as deposits of these taxes on the day that you pay wages (including the advance EIC payment) to your employees. The payments are treated as deposits of these taxes in the following order: (1) income tax withholding, (2) withheld employee social security and Medicare taxes, and (3) the employer's share of social security and Medicare taxes.

U.S. possessions. If you are in American Samoa, the Commonwealth of the Northern Mariana Islands, Guam, or the U.S. Virgin Islands, consult your local tax office for information on the EIC. You cannot take advance EIC payments into account on Form 941-SS or Form 944-SS.

Required Notice to Employees

You must notify employees who have no federal income tax withheld that they may be able to claim a tax refund because of the EIC. Although you do not have to notify employees who claim exemption from withholding on Form W-4, Employee's Withholding Allowance Certificate, about the EIC, you are encouraged to notify any employees whose wages for 2006 were less than $36,348 ($38,348 if married filing jointly) that they may be eligible to claim the credit for 2006. This is because eligible employees may get a refund of the amount of EIC that is more than the tax that they owe.

You will meet this notification requirement if you issue the employee Form W-2 with the EIC notice on the back of Copy B, or a substitute Form W-2 with the same statement. You will also meet the requirement by providing Notice 797, Possible Federal Tax Refund Due to the Earned Income Credit (EIC), or your own statement that contains the same wording.

If a substitute for Form W-2 is given to the employee on time but does not have the required statement, you must notify the employee within 1 week of the date that the substitute for Form W-2 is given. If Form W-2 is required but is not given on time, you must give the employee Notice 797 or your written statement by the date that Form W-2 is required to be given. If Form W-2 is not required, you must notify the employee by February 7, 2007.

11. Depositing Taxes

In general, you must deposit federal income tax withheld and both the employer and employee social security and Medicare taxes plus or minus any prior period adjustments to your tax liability (minus any advance EIC payments). You must deposit by using the Electronic Federal Tax Payment System (EFTPS) or by mailing or delivering a check, money order, or cash with Form 8109, Federal Tax Deposit Coupon, to a financial institution that is an authorized depositary for federal taxes. Some taxpayers are required to deposit using EFTPS. See How To Deposit on page 21 for information on electronic deposit requirements for 2007.

Payment with return. You may make a payment with Form 941 or Form 944 instead of depositing if one of the following applies.

  1. You report less than a $2,500 tax liability for the quarter on line 10 of Form 941 (or for the year on line 9 of Form 944), and you pay in full with a timely filed return. (However, if you are unsure that you will report less than $2,500, deposit under the appropriate rules so that you will not be subject to failure-to-deposit penalties.)
  2. You are a monthly schedule depositor (defined below) and make a payment in accordance with the Accuracy of Deposits Rule discussed on page 21. This payment may be $2,500 or more.

Employers who have been notified to file Form 944 can pay their fourth quarter tax liability with a timely filed return if the fourth quarter tax liability is less than $2,500. Employers must have deposited any tax liability due for the first, second, and third quarters according to the deposit rules to avoid failure-to-deposit penalties for deposits during those quarters.

Separate deposit requirements for nonpayroll (Form 945) tax liabilities. Separate deposits are required for nonpayroll and payroll income tax withholding. Do not combine deposits for Forms 941 (or Form 944) and 945 tax liabilities. Generally, the deposit rules for nonpayroll liabilities are the same as discussed below, except that the rules apply to an annual rather than a quarterly return period. Thus, the $2,500 threshold for the deposit requirement discussed above applies to Form 945 on an annual basis. See the separate Instructions for Form 945 for more information.

When To Deposit

There are two deposit schedules—monthly or semiweekly—for determining when you deposit social security, Medicare, and withheld income taxes. These schedules tell you when a deposit is due after a tax liability arises (for example, when you have a payday). Before the beginning of each calendar year, you must determine which of the two deposit schedules that you are required to use. The deposit schedule that you must use is based on the total tax liability that you reported on Form 941 during a lookback period discussed below. Your deposit schedule is not determined by how often you pay your employees or make deposits. See special rules for Forms 944 and 945 below. See Application of Monthly and Semiweekly Schedules on page 20.

These rules do not apply to federal unemployment (FUTA) tax. See section 14 for information on depositing FUTA tax.

Lookback period. If you are a Form 941 filer, your deposit schedule for a calendar year is determined from the total taxes (that is, not reduced by any advance EIC payments) reported on line 8 of your Forms 941 in a four-quarter lookback period. The lookback period begins July 1 and ends June 30 as shown in Table 1 below. If you reported $50,000 or less of taxes for the lookback period, you are a monthly schedule depositor; if you reported more than $50,000, you are a semiweekly schedule depositor.

Accuracy of Deposits Rule

You are required to deposit 100% of your tax liability on or before the deposit due date. However, penalties will not be applied for depositing less than 100% if both of the following conditions are met.

§Any deposit shortfall does not exceed the greater of $100 or 2% of the amount of taxes otherwise required to be deposited and

§The deposit shortfall is paid or deposited by the shortfall makeup date as described below.

Makeup Date for Deposit Shortfall:

§Monthly schedule depositor. Deposit the shortfall or pay it with your return by the due date of your return for the return period in which the shortfall occurred. You may pay the shortfall with your return even if the amount is $2,500 or more.

§Semiweekly schedule depositor.

Deposit by the earlier of:

    • The first Wednesday or Friday (whichever comes first) that falls on or after the 15th of the month following the month in which the shortfall occurred or
    • The due date of your return (for the return period of the tax liability).
