previous topic occurrence Excess Social Security or Railroad Retirement Tax Withholding next topic occurrence

Most employers must withhold social security tax from your wages. In some cases, however, the federal government and state and local governments do not have to withhold social security tax from their employees' wages. If you work for a railroad employer, that employer must withhold tier 1 railroad retirement (RRTA) tax and tier 2 RRTA tax.

Two or more employers.(p52)


rule

If you worked for two or more employers in 2008, too much social security tax or tier 1 RRTA tax may have been withheld from your pay. You may be able to claim the excess as a credit against your income tax when you file your return. Table 3-2 shows the maximum amount that should have been withheld for any of these taxes for 2008. Figure the excess withholding on the appropriate worksheet on page 53.

Joint returns.(p52)

If you are filing a joint return, you cannot add any social security or tier 1 RRTA tax withheld from your spouse's income to the amount withheld from your income. You must figure the excess separately for both you and your spouse to determine if either of you has excess withholding.
Note.All wages are subject to Medicare tax withholding.

Employer's error.(p52)


rule
spacer

If any one employer withheld too much social security or tier 1 RRTA tax, you cannot claim the excess as a credit against your income tax. The employer should adjust the tax for you. If the employer does not adjust the overcollection, you can file a claim for refund using Form 843, Claim for Refund and Request for Abatement.

Example.(p52)

In 2008, Tom Martin earned $58,000 working for Company A and $47,200 working for Company B. Company A withheld $3,596 for social security tax. Company B withheld $2,926.40 for social security tax. Because he worked for two employers and earned more than $102,000, he had too much social security tax withheld. Tom figures his credit of $198.40, as shown on the illustrated Worksheet 3-1 below.
