Frequently Asked Questions

What is the Social Security wage base?

The wage base is the maximum earnings subject to Social Security tax—$168,600 in 2024. Earnings above this amount aren't taxed for Social Security (though Medicare has no cap). The wage base increases annually based on average wage growth.

Do I pay Social Security tax on investment income?

No. Social Security tax only applies to earned income (wages, self-employment). Investment income like dividends, interest, capital gains, and rental income is not subject to Social Security tax. However, it may be subject to Net Investment Income Tax (3.8%).

What if I have multiple employers?

If combined wages from multiple employers exceed the wage base, you can claim a credit on your tax return for excess Social Security tax withheld. Each employer withholds based on what you earn there—they don't know about other jobs.
