Is Social Security taxable?
It depends on your other income. None of your benefit is taxed if half of it plus your other income is $25,000 or less for a single filer, or $32,000 or less for a couple filing jointly. Above that, up to 85% can be taxable.
Net benefits, box 5 of Form SSA-1099. For a joint return, add both spouses' amounts.
Wages, pensions, taxable interest, dividends, IRA withdrawals and other taxable income.
Such as a deductible IRA contribution. Leave at 0 if you have none.

How the IRS works it out
The calculator follows Worksheet 1 in IRS Publication 915. The worksheet adds half of your benefits to your other income and tax-exempt interest, subtracts certain adjustments, and compares the result with a base amount:
- $25,000 if you are single, head of household or a qualifying surviving spouse.
- $25,000 if you are married filing separately and lived apart from your spouse all year.
- $32,000 if you are married filing jointly.
If the result is at or below the base amount, none of your benefits are taxable. Above it, generally up to 50% of your benefits are taxable. Up to 85% can be taxable when half of your benefits plus all your other income is more than $34,000, or $44,000 if you are married filing jointly.
If you are married filing separately and lived with your spouse at any time in the year, the worksheet skips the base amount and up to 85% of your benefits are taxable.
Check it against the IRS example
The filled-in worksheet in Publication 915 has benefits of $5,980 and a line 8 total of $31,980 for a single filer, and arrives at taxable benefits of $2,990. Enter benefits of 5,980 and other income of 28,990 above and you get the same figure.
What this does not cover
Publication 915 also describes a lump-sum election for benefit payments that were for an earlier year. This calculator does not apply it. State income tax on benefits is separate and is not covered here.
