For most workers, the answer to whether you get Social Security and Medicare tax back is no: those payroll deductions fund the trust funds that pay your future retirement, disability, and hospital benefits, so the money stays with the government and comes back later as benefits rather than as a refund. But there are specific situations where you can recover what was withheld. The main ones are holding two or more jobs that together pushed you past the Social Security wage cap, having the Additional Medicare Tax withheld when your filing status meant you did not owe it, being in a job category that is legally exempt from FICA, having a single employer withhold by mistake, or correcting an overpayment of self-employment tax.
If any of those fit your year, the refund is real and you have to claim it. The IRS will not send it on its own.
Two or More Jobs Over the Social Security Wage Cap
This is the most common refund scenario. Social Security tax is 6.2% of your wages, but only up to an annual earnings cap. For 2026, that cap is $184,500, which means the most Social Security tax any single worker should pay in a year is $11,439.1Social Security Administration. Contribution and Benefit Base
When you work for two or more unrelated employers in the same year, each one withholds the 6.2% based only on what it pays you. Neither knows about the other. If your combined wages cross $184,500, more Social Security tax came out of your paychecks than you actually owed.
You claim the excess as a credit on Schedule 3 of your Form 1040. It reduces your tax bill, and if the credit is bigger than what you owe, the IRS refunds the difference.2Internal Revenue Service. Topic No. 608, Excess Social Security and RRTA Tax Withheld You do not contact the Social Security Administration and you do not need to prove the employers did anything wrong. They did not; the system puts the burden on you to reconcile at tax time.
Note that this only works for Social Security tax. The regular 1.45% Medicare tax has no cap, so having multiple jobs cannot create a Medicare overpayment.
Additional Medicare Tax Withheld When You Did Not Owe It
Higher earners owe an extra 0.9% Medicare tax above a threshold that depends on filing status: $200,000 for single filers, $250,000 for married filing jointly, and $125,000 for married filing separately.3Internal Revenue Service. Questions and Answers for the Additional Medicare Tax
Here is where overwithholding creeps in. Your employer is required to start withholding the extra 0.9% once it pays you more than $200,000, no matter how you file. If you are married filing jointly and your household income stays under $250,000, you may have had the tax taken out even though you never owed it.
To get it back, file Form 8959, Additional Medicare Tax, with your return. The form reconciles what was withheld against what you actually owe at your filing status, and any excess becomes a credit against your total tax, refundable if it exceeds what you owe.4Internal Revenue Service. Instructions for Form 8959 Married couples where one spouse earned over $200,000 but combined income stayed below $250,000 are the group that most often misses this.
A Single Employer Overwithheld by Mistake
If one employer took out too much Social Security or Medicare tax, you cannot just claim it on your return the way you would with multiple-employer overpayments. Start by asking the employer to correct the error and refund the overcollection directly.5Internal Revenue Service. Instructions for Form 843
If the employer refuses, or has gone out of business, file Form 843, Claim for Refund and Request for Abatement, with the IRS. Attach the W-2 showing the withholding, explain the overcollection, and if you can, include a statement from the employer confirming the error. If you cannot get one, say why on the form and provide what you have.7Internal Revenue Service. Instructions for Form 843
You Were Exempt From FICA but It Was Withheld Anyway
Some workers are legally exempt from Social Security and Medicare tax. If your employer withheld it anyway, you can recover the money.
The recovery path is the same as a single-employer overwithholding error. Ask the employer to fix it first. If that does not work, file Form 843 with the IRS, attach your W-2, and include documentation of your exempt status.5Internal Revenue Service. Instructions for Form 843
Self-Employment Tax Corrections
If you are self-employed, you pay the equivalent of both the employee and employer shares through self-employment tax on Schedule SE: 12.4% for Social Security on earnings up to $184,500, and 2.9% for Medicare on all net earnings, for a combined 15.3%.11Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes)
You cannot get SE tax refunded just because you wish you had paid less. But if you overpaid because you miscalculated your net earnings, usually by missing legitimate business deductions, you can file Form 1040-X with a corrected Schedule SE. If the corrected amount is lower than what you originally paid, the IRS refunds the difference.12Internal Revenue Service. Instructions for Form 1040-X
Separately, every self-employed taxpayer is allowed to deduct half of their SE tax as an adjustment to gross income on Schedule 1. It is not a refund, but it meaningfully reduces your overall tax bill, and it is one of the most commonly overlooked items for people new to self-employment.13Office of the Law Revision Counsel. 26 U.S. Code 164 – Taxes
Household Employers Under the Nanny Tax Threshold
If you employ someone in your home, such as a nanny, housekeeper, or caregiver, you owe FICA on their wages only if you pay them $3,000 or more in cash during 2026. Below that, neither you nor the worker owes it.14Internal Revenue Service. Publication 926 (2026), Household Employer’s Tax Guide
If you withheld FICA from a household worker and the year’s total came in under $3,000, repay the worker what you withheld from them. To recover the employer share you already sent to the IRS, file a corrected Schedule H with Form 1040-X. You can only claim that refund after you have repaid the employee’s share or gotten their written consent to file the claim.14Internal Revenue Service. Publication 926 (2026), Household Employer’s Tax Guide
Does Getting a Refund Hurt Your Future Social Security Benefits?
No. Social Security only counts earnings up to the annual cap when it calculates your future benefit. If you earned $250,000 across two jobs in 2026, only $184,500 goes on your earnings record whether or not you claim a refund of the excess tax.15Social Security Administration. Social Security Tax Limits on Your Earnings The refund corrects tax you paid on wages that were never going to count toward your benefit in the first place. There is no penalty for claiming it.
How Long You Have to Claim the Refund
Every FICA refund claim has a deadline. You must file within three years of the date you filed the original return, or within two years of the date you paid the tax, whichever is later.16Internal Revenue Service. Time You Can Claim a Credit or Refund A return filed before the due date is treated as filed on the due date for this calculation. After the window closes, the overpayment is gone. If you had multiple jobs in a recent year or think an old employer withheld in error, pull your W-2s and check now.
