Social Security tax stops coming out of your paycheck the moment your year-to-date gross wages cross the annual taxable wage base. For 2026, that ceiling is $184,500.1Social Security Administration. Contribution and Benefit Base Once you pass it, the 6.2% deduction disappears from your next check and stays gone until January 1, when the counter resets and withholding starts again from your first dollar of pay.
The 2026 Wage Base and How the Cutoff Works
The maximum any employee can pay in Social Security tax for 2026 is $11,439, which is 6.2% of $184,500.1Social Security Administration. Contribution and Benefit Base Your payroll system tracks cumulative wages and shuts off the withholding automatically. You don’t file paperwork, notify HR, or ask for anything. It just stops.
A worker on a $250,000 salary paid biweekly crosses the ceiling around mid-October and takes home larger checks for the rest of the year. Come January, those larger checks disappear. The wage base itself moves each year based on the national average wage index, which is why the stopping point shifts. It was $176,100 in 2025 and rose to $184,500 for 2026.2Social Security Administration. Social Security Tax Limits on Your Earnings
What Actually Stops on Your Pay Stub
Only the Social Security line stops. Medicare withholding of 1.45% keeps going on every dollar you earn, with no annual ceiling.3Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates Once your wages pass $200,000 in a calendar year, an Additional Medicare Tax of 0.9% starts coming out on top of that. So the FICA portion of your check gets smaller when Social Security stops, but it never drops to zero.
If you compare pay stubs side by side, you’re looking for the “OASDI” or “Social Security” line specifically. That’s the one that flatlines mid-year for high earners.
If You Work Two Jobs, You May Overpay
Each employer withholds 6.2% independently, up to the wage base, without any visibility into what other employers are taking out. If your combined wages from multiple jobs exceed $184,500, you’ll overpay Social Security tax across the year.4Internal Revenue Service. Topic No. 608, Excess Social Security and RRTA Tax Withheld
You get it back on your federal return. The excess goes on Schedule 3 of Form 1040, Line 11, as a credit against your income tax. If the credit runs larger than your tax bill, the IRS refunds the difference.4Internal Revenue Service. Topic No. 608, Excess Social Security and RRTA Tax Withheld At year-end, add up the Social Security wages box on every W-2 you received and check whether the total sits above the cap.
This route only works when the overpayment comes from multiple employers. If a single employer withheld too much, you have to go back to that employer to get it corrected. If they refuse or no longer exist, you can file Form 843 with the IRS and attach the W-2 as proof.5Internal Revenue Service. Instructions for Form 843, Claim for Refund and Request for Abatement
Self-Employed Workers Hit the Same Ceiling
If you work for yourself, the same $184,500 cap applies, but you pay both halves: 12.4% on the Social Security portion.1Social Security Administration. Contribution and Benefit Base The tax runs on 92.35% of your net self-employment income, and you can deduct half of the total self-employment tax when calculating adjusted gross income.6Internal Revenue Service. Topic No. 554, Self-Employment Tax
Have a W-2 job on the side? Those wages count first against the cap. Whatever room is left underneath is the amount of self-employment income that still owes the 12.4%. If your W-2 wages hit $150,000, only $34,500 of your self-employment earnings are subject to the Social Security portion.7Internal Revenue Service.

Workers Who Never Owe Social Security Tax
A narrow set of workers never see the 6.2% deduction at all. The exemptions turn on the type of employment or the worker’s legal status, and none of them are elective for the average employee.
Students Working at Their Own School
If you’re enrolled at a college or university and work for the same institution, your wages are generally exempt. The job has to be incidental to your education.8eCFR. 26 CFR 31.3121(b)(10)-2 A graduate student teaching assistant fits. A full-time staff member who takes one class does not. The exemption only holds as long as student status does.
Some State and Local Government Employees
Public-sector workers covered by a qualifying state or local pension system, and not brought into Social Security through a Section 218 agreement, don’t have the tax withheld.9Internal Revenue Service. State and Local Government Employees Social Security and Medicare Coverage This is most common for police, firefighters, and teachers in states that run their own retirement systems.
Members of Certain Religious Groups
Members of recognized religious groups that have provided for their dependents since at least December 31, 1950, and that conscientiously oppose insurance benefits, can apply for an exemption using Form 4029. Approval stops both Social Security and Medicare tax, and also permanently waives any benefits under those programs.10Internal Revenue Service. Form 4029, Application for Exemption From Social Security and Medicare Taxes and Waiver of Benefits
Nonresident Alien Students and Scholars
Foreign students and exchange visitors on F-1, J-1, or M-1 visas are exempt from Social Security and Medicare tax while they remain nonresident aliens, which is generally less than five calendar years in the U.S. The work must be authorized and tied to the purpose of the visa.11Internal Revenue Service. Foreign Student Liability for Social Security and Medicare Taxes Once the person becomes a resident alien for tax purposes, withholding starts. Dependents on F-2, J-2, or M-2 visas don’t qualify.
Election Workers Below the Threshold
Election officials and election workers earning less than $2,500 in a calendar year from that work are exempt on those earnings.12Social Security Administration. Employment Coverage Thresholds Most poll workers fall under the threshold and never see the deduction.
Reaching Retirement Age Doesn’t Stop the Tax
Turning 62, 67, or 72 changes nothing about payroll tax. If you keep working, the 6.2% comes out of your wages exactly as it did before, and the same $184,500 cap applies.13Social Security Administration. What Happens if I Work and Get Social Security Retirement Benefits? Collecting Social Security benefits doesn’t change it either. There’s no age-based cutoff for the tax itself.
The upside is that continued earnings can raise your future benefit. Social Security recalculates each year and, if a recent year of earnings replaces a lower-earning year in your record, your monthly check goes up.
A separate rule, the retirement earnings test, can temporarily reduce benefit checks for people who claim before full retirement age and keep working. That’s a benefit reduction, not a change to payroll withholding, and it disappears once you reach full retirement age.
