Social Security taxes stop once you reach the wage base limit each year
Social Security taxes (the 6.2% withheld from your paycheck) stop coming out once you earn more than a set amount in a single calendar year. That amount changes every year—in 2024 it is $168,600, but it rises each January based on wage growth. Once you cross that threshold, your employer stops taking Social Security tax from your remaining paychecks for that year.
This is different from Medicare tax, which has no wage limit and continues on every dollar you earn, no matter how much you make. The two are separate: Social Security tax stops, Medicare tax does not.
If you work for multiple employers in the same year, each one withholds Social Security tax independently until you hit the limit across all jobs combined. You may end up overpaying, but you can claim the overage back when you file your tax return.
Key Takeaways
- Social Security tax stops for the year once your total wages reach the annual wage base limit, which is $168,600 in 2024 and increases each January.
- The 6.2% Social Security tax applies only to wages below the limit; Medicare tax of 1.45% continues on all wages with no upper limit.
- If you work multiple jobs, each employer withholds Social Security tax separately, and you may overpay if your combined earnings exceed the limit.
- Overpaid Social Security tax can be recovered as a credit on your federal tax return when you file.
- Self-employed people pay both the employee and employer portions (12.4% total) but can deduct half of it on their tax return.
How the wage base limit works each year
The Social Security Administration sets a new wage base limit every October for the following year. This limit is tied to the average wage index—a measure of how much American workers earn on average. When average wages go up, the limit goes up with it. The limit has risen nearly every year since Social Security began.
Once you earn wages equal to that year's limit, your employer receives a notification (usually automatic through payroll software) to stop withholding Social Security tax. This happens on the next paycheck after you cross the threshold. If you are paid weekly, you might cross the limit mid-week; if you are paid monthly, you might cross it mid-month. The cutoff is based on your cumulative earnings for the calendar year, not on when the money hits your account.
The wage base limit applies to W-2 wages only. Income from investments, rental property, or other sources does not count toward the limit and does not trigger the stop in withholding.
What happens if you work multiple jobs
Each employer withholds Social Security tax based only on what you earn at that job, not on your total earnings across all jobs. This means if you earn $100,000 at Job A and $80,000 at Job B in 2024, both employers will withhold Social Security tax on their full amounts, even though your combined earnings ($180,000) exceed the $168,600 limit.
In this scenario, you would overpay Social Security tax by the amount withheld on $11,400 (the difference between $180,000 and $168,600). That overpayment is 6.2% of $11,400, or about $707. You recover this money by claiming it as a credit on your federal tax return (Form 1040, line 24) when you file. You do not need to contact your employers or the Social Security Administration—the IRS handles the refund automatically.
If you have overpaid, make sure both employers' W-2 forms are included with your tax return so the IRS can see the total withholding across all jobs.
Self-employed workers and the Social Security tax cap
If you are self-employed, you pay both the employee portion (6.2%) and the employer portion (6.2%) of Social Security tax, for a total of 12.4% on net self-employment income. The wage base limit still applies—once your net self-employment income reaches $168,600 in 2024, you stop paying the 12.4% on additional earnings.
You calculate self-employment tax on Schedule SE (Form 1040) and pay it when you file your tax return or through quarterly estimated tax payments. Unlike employees, you do not have an employer withholding the tax automatically, so you must set aside money or pay in installments to avoid a large bill at tax time.
Self-employed people can deduct half of their self-employment tax on their tax return, which reduces their taxable income. This deduction appears on Form 1040 and helps offset the fact that self-employed workers pay both sides of the tax.
Medicare tax has no wage limit
While Social Security tax stops at the wage base limit, Medicare tax continues on every dollar you earn, no matter how much. The standard Medicare tax rate is 1.45% for employees and 1.45% for employers (2.9% total for self-employed workers). There is no annual cap.
High earners pay an additional 0.9% Medicare tax on wages above $200,000 (single filers) or $250,000 (married filing jointly). This additional tax has no cap either and continues for the rest of the year once you cross the threshold. Your employer should withhold this automatically if your wages exceed the threshold.
Because Medicare tax has no limit, your paycheck will continue to have a Medicare withholding even after Social Security tax stops.
The wage base limit for recent and upcoming years
The wage base limit has increased most years as average wages have risen. Here are the limits for recent years and what is known about the near future:
| Year | Wage Base Limit |
|---|---|
| 2022 | $147,000 |
| 2023 | $160,200 |
| 2024 | $168,600 |
| 2025 | $176,100 |
The Social Security Administration announces the next year's limit in October, so you can plan ahead if you expect to reach the cap. If you are close to the limit late in the year, you can estimate when your employer will stop withholding and adjust your budget accordingly.
Recovering overpaid Social Security tax on your tax return
If you overpaid Social Security tax because you worked multiple jobs or changed jobs mid-year, you recover the overpayment when you file your federal tax return. The overpaid amount is treated as a credit, which means it reduces your tax bill dollar-for-dollar or increases your refund.
To claim the credit, you need all your W-2 forms showing the total Social Security tax withheld at each job. Add up the Social Security tax columns from all W-2s. If the total exceeds 6.2% of the wage base limit for that year, you have overpaid. The difference is your credit.
You enter this credit on Form 1040, line 24 (labeled "Other credits"). You do not need to do any calculations yourself—the IRS will verify the amount using your W-2 data. If you file electronically, tax software usually calculates this automatically.
Frequently Asked Questions
Does Social Security tax stop permanently or just for that year?
It stops only for that calendar year. On January 1, the withholding resets, and your employer begins taking Social Security tax again from your first paycheck of the new year. The wage base limit is different each year, so the point at which withholding stops may be different too.
What if I change jobs after reaching the wage base limit?
Your new employer does not know that you have already paid the maximum Social Security tax at your previous job. They will begin withholding Social Security tax from your first paycheck, even though you have already hit the limit for the year. You will overpay, but you recover the overpayment on your tax return.
Do I need to tell my employer when I reach the wage base limit?
No. Payroll systems track cumulative earnings automatically and stop withholding once the limit is reached. If your employer uses modern payroll software, the stop happens without any action on your part. If you notice Social Security tax is still being withheld after you have earned more than the limit, contact your payroll department to verify the calculation.
Can I request that my employer keep withholding Social Security tax after I hit the limit?
No. The law requires employers to stop withholding once the wage base limit is reached. You cannot opt to pay more, even if you want to. The withholding is mandatory and stops automatically.
Does the wage base limit affect my Social Security benefits later?
No. Your future Social Security benefit is based on your highest 35 years of earnings, and the wage base limit does not change how much of your income counts toward that calculation. Earnings above the limit in any year straightforward do not contribute additional Social Security credits, but they also do not reduce the credits you earned on income below the limit.
