Social Security tax stops once you hit the wage cap for the year

Social Security tax (also called OASDI tax) stops coming out of your paycheck once your earnings reach a certain limit each year. For 2024, that limit is $168,600. Once you earn that much in wages, your employer stops taking the 6.2% Social Security tax from your paychecks for the rest of the year. The Medicare portion of your payroll tax (1.45%) continues regardless of how much you earn.

This wage cap changes every year because it is tied to national wage growth. The Social Security Administration announces the new limit in October for the following year. If you work for multiple employers or change jobs during the year, you might pay more than the annual cap across all your jobs combined — but you can claim a credit for the overpayment when you file your taxes.

Key Takeaways

  • The Social Security wage cap for 2024 is $168,600; once you earn that amount, Social Security tax stops being withheld from your paychecks.
  • The wage cap increases each year based on national wage growth and is announced by the Social Security Administration in October.
  • If you work multiple jobs and pay Social Security tax on more than the annual cap across all employers, you can claim the overpayment as a credit on your tax return.
  • Medicare tax (1.45% of wages) has no wage cap and continues to be withheld no matter how much you earn.
  • High earners pay an additional 0.9% Medicare tax on wages above $200,000 (single filers) or $250,000 (married filing jointly).

How the wage cap works during the year

Your employer calculates whether you have hit the wage cap by tracking your cumulative earnings throughout the year. Once your year-to-date gross pay reaches $168,600 (for 2024), your employer removes the 6.2% Social Security withholding from your next paycheck and all paychecks after that. The exact paycheck where this happens depends on your pay frequency and when you started earning during the year.

If you are paid biweekly, you might hit the cap in late October or November. If you are paid monthly, it might happen in September or October. If you started a job partway through the year, you might not hit the cap at all. Your pay stub will show when the Social Security tax stops — you will see the line item disappear or show $0.00 for that withholding.

What happens if you work multiple jobs

When you work for more than one employer, each employer withholds Social Security tax independently based on what they pay you. Neither employer knows what you earn at your other job. This means you can end up paying Social Security tax on more than $168,600 in total wages across all jobs combined.

For example, if you earn $100,000 at Job A and $80,000 at Job B, you will pay the full 6.2% Social Security tax on both amounts — a total of $11,160 in Social Security tax instead of the $10,453 you would owe if you had earned $180,000 at a single job. When you file your federal income tax return, you can claim the overpayment as a credit. The IRS will refund the excess Social Security tax you paid, or you can explore it to taxes you owe.

The wage cap changes every year

The Social Security wage cap is not fixed. It adjusts annually based on the average wage index — a measure of how much workers earned on average across the country in the prior year. The Social Security Administration calculates the new cap and announces it in October for the following year. This means the limit you see on your 2024 paychecks will be different from the limit in 2025.

Recent years show how the cap has grown: in 2023 it was $160,200, in 2024 it is $168,600, and in 2025 it will be $176,100. The increase reflects wage growth in the economy. If you are a high earner, you should check the current year's cap in October so you know roughly when the withholding will stop.

Medicare tax has no wage cap

While Social Security tax stops at the wage cap, Medicare tax does not. The standard Medicare tax rate is 1.45% of all your wages, no matter how much you earn. Your employer withholds this amount from every paycheck throughout the year.

If you earn more than $200,000 (for single filers) or $250,000 (for married couples filing jointly), you also pay an additional 0.9% Medicare tax on wages above those thresholds. This additional tax has no cap either. It was introduced in 2013 as part of the Affordable Care Act and applies to high earners only.

Self-employed workers and the wage cap

If you are self-employed, you pay both the employer and employee portions of Social Security tax — a total of 12.4% instead of 6.2%. The wage cap still applies. Once your net self-employment income reaches $168,600 (for 2024), you stop paying the Social Security portion of self-employment tax on income above that amount.

You calculate this on Schedule SE when you file your taxes, not on your paychecks. Self-employed workers do not have an employer withholding the tax, so you either pay estimated taxes quarterly or settle the full amount when you file. The Medicare portion of self-employment tax (2.9% total, or 3.8% if you earn above the threshold) continues on all income with no cap.

What to do if you overpaid Social Security tax

If you worked multiple jobs or changed employers during the year and paid Social Security tax on more than the annual wage cap, you will need to claim the overpayment on your tax return. When you file, the IRS will calculate how much excess Social Security tax you paid and either refund it to you or explore it as a credit against other taxes you owe.

You do not need to do anything special to claim this credit — it happens automatically when you file your return. If you file electronically, the software will calculate it. If you file by paper, the IRS will calculate it for you. Make sure all your W-2 forms are reported accurately so the IRS can see the total Social Security tax you paid across all employers.
