Frequently Asked Questions

What is the 2025 Social Security tax rate and wage base?

For 2025, the Social Security tax rate is 6.2% for employees (with employers matching another 6.2%) and 12.4% for self-employed individuals. The wage base limit is $168,600, meaning no Social Security tax is owed on income above this amount.

How does Social Security tax work with multiple jobs?

Each employer withholds Social Security tax separately up to the wage base limit. If your combined wages from all jobs exceed $168,600, you may have excess Social Security tax withheld, which you can claim as a refund when filing your tax return.

What is the difference between employee and self-employment Social Security tax?

Employees pay 6.2% while their employers pay the matching 6.2%. Self-employed individuals pay the full 12.4% but can deduct half (the employer portion) as a business expense on their tax return.

Can I get a refund if too much Social Security tax is withheld?

Yes, if you have multiple jobs and your combined wages exceed the $168,600 wage base, resulting in excess Social Security tax withholding, you can claim the excess as a refund on your tax return.

How do Social Security taxes affect my future benefits?

Social Security taxes fund your future retirement, disability, and survivor benefits. You need 40 quarters of coverage (10 years) for retirement benefits, and the amount of your benefits is based on your highest 35 years of earnings.

What happens if I'm receiving Social Security disability benefits?

If you're receiving SSDI or SSI, you may still be able to work and pay Social Security taxes within certain income limits. Work activity is encouraged and there are special rules to protect your benefits while you test your ability to work.
