Social security tax withholding means one of two things. For workers, it is the 6.2% Social Security tax your employer takes out of each paycheck, up to a yearly wage cap of $184,500 in 2026. For retirees and other beneficiaries, it is the federal income tax you can choose to have withheld from your Social Security benefits, at 7%, 10%, 12% or 22%.
This guide covers both. You will learn how much is withheld from wages, when withholding stops for the year, what to do if too much was taken, and how to start, change or stop tax withholding from your monthly benefit. All figures are as of October 2026.
Social security tax withholding: quick facts
| Item | 2026 figure |
|---|---|
| Employee Social Security tax rate | 6.2% of wages |
| Employer matching rate | 6.2% of wages |

| Wage base (maximum taxable earnings) | $184,500 (up from $176,100 in 2025) |
| Maximum employee Social Security tax | $11,439 |
| Medicare tax (separate) | 1.45% each for employee and employer, no wage cap |
| Additional Medicare tax | 0.9% withheld on wages over $200,000 |
| Withholding choices on benefits | 7%, 10%, 12% or 22% of the monthly payment |
How Social Security tax is withheld from your paycheck
Your employer withholds 6.2% of your wages for Social Security tax and pays a matching 6.2% from its own funds. Together with Medicare tax, this is often called FICA tax, after the Federal Insurance Contributions Act.
On a pay stub, the line may read “Social Security,” “OASDI” (Old-Age, Survivors, and Disability Insurance) or “FICA-SS.” For example, on a $2,000 paycheck the Social Security withholding is $124. The Medicare line is separate and works out to $29 on the same check.
Unlike federal income tax withholding, you cannot change the Social Security rate on a Form W-4. The rate is set by law and applies to most wages, tips and bonuses. The Social Security Administration lists the current rates and limits on its contribution and benefit base page.
The 2026 wage base: when withholding stops
Social Security tax applies only up to the yearly wage base. In 2026 that limit is $184,500, so the most an employee can owe through one job is $11,439.
Once your wages from an employer reach $184,500 for the year, that employer should stop withholding Social Security tax until January. Medicare tax keeps going, because it has no wage cap. In addition, employers must withhold an extra 0.9% Additional Medicare tax on wages above $200,000, with no employer match, according to IRS Topic 751.
| Year | Wage base | Maximum employee tax |
|---|---|---|
| 2025 | $176,100 | $10,918.20 |
| 2026 | $184,500 | $11,439.00 |
The wage base usually rises each year with national average wages. The Social Security Administration announces the new figure each October with the cost-of-living adjustment.
What if too much Social Security tax was withheld?
If you worked for two or more employers in the same year, you may have paid more than the maximum. In that case, you can claim the extra amount as a credit on your federal tax return.
Each employer must withhold up to the wage base on its own, without regard to what other employers paid you. So a worker who earned $120,000 at one job and $90,000 at another in 2026 would have $13,020 withheld in total, which is $1,581 more than the $11,439 limit. The excess is claimed on Schedule 3 of Form 1040.
The rule is different if a single employer withheld too much. Here, the credit on your return does not apply. Instead, you ask that employer to refund the overpayment and correct its records.
Self-employed workers
Self-employed people pay both halves, a total of 12.4% Social Security tax, through self-employment tax on Schedule SE. The same $184,500 wage base applies in 2026, and wages from a job count toward it first.
No one withholds this tax for you. As a result, self-employed workers usually pay it through quarterly estimated tax payments. Half of the self-employment tax is deductible when figuring income tax.
Federal tax withholding from Social Security benefits
Social Security benefits can be taxable, and you can ask the Social Security Administration to withhold federal income tax from each payment. The only choices are 7%, 10%, 12% or 22% of your monthly benefit.
Are your benefits taxable?
Federal tax depends on your “combined income,” which is your adjusted gross income plus nontaxable interest plus half of your benefits. According to the Social Security Administration, you may owe tax on benefits when combined income is above $25,000 for an individual filer or $32,000 for a joint filer. Depending on income, up to 50% or up to 85% of benefits can be taxable. No one pays tax on more than 85% of their benefits.
For tax years 2025 through 2028, federal law also adds a temporary extra deduction of up to $6,000 for people age 65 or older, which phases out at higher incomes. It can lower your tax, but it does not make benefits tax-free.
How to start, change or stop withholding
You have three ways to set up withholding on your benefits:
- Online: sign in to your my Social Security account and choose the option to change tax withholding.
- By phone: call the Social Security Administration at 1-800-772-1213 (TTY 1-800-325-0778), Monday through Friday, 8 a.m. to 7 p.m.
- By form: complete IRS Form W-4V, Voluntary Withholding Request, and mail it to or drop it off at your local Social Security office.
You can use the same methods to change the percentage or stop withholding. Changes can take a month or two to show up in your payment. The Social Security Administration explains the process on its tax withholding page.
Withholding vs. estimated tax payments
Withholding is optional. If you prefer, you can make quarterly estimated tax payments to the IRS instead. Some retirees also raise withholding on a pension or IRA distribution to cover the tax on their benefits.
State taxes on benefits
Most states do not tax Social Security benefits, but a few do, often with exemptions for lower incomes. The Social Security Administration withholds federal tax only, so check your state revenue department if your state taxes benefits.
Common mistakes to avoid
- Confusing the two meanings. Payroll Social Security tax funds the program. Withholding on benefits is income tax on what you receive.
- Expecting a refund of normal payroll tax. Social Security tax up to the wage base is not refundable just because you had low income.
- Missing excess withholding. Workers with two high-paying jobs in one year should compare total withholding to the yearly maximum.
- Picking no withholding without a plan. If benefits are taxable and nothing is withheld, you may owe a large bill and possibly an underpayment penalty.
- Using old numbers. The wage base changes every year, so check the current figure in January.
Social Security benefits also come up in disputes over who is entitled to payments. Our guide explaining what a claimant is in Social Security and other claims covers that term. For a recent tax-software dispute, see our TurboTax lawsuit update.
Conclusion
Social security tax withholding covers two separate things. Workers have 6.2% withheld from wages up to $184,500 in 2026, with a $11,439 maximum, and anyone who overpaid through several employers can claim the excess on their tax return. Beneficiaries, on the other hand, can choose to have 7%, 10%, 12% or 22% of each payment withheld for federal income tax, and can change that choice online, by phone or with Form W-4V. Because rates, limits and tax rules change, check the Social Security Administration and IRS figures each year. A tax professional can help with your own situation.
