Is Social Security Taxable? The Federal Tax on Benefits

Social Security is taxable for some people. Up to 85% of your benefits can count as income on your federal tax return, and none of it does if half your benefits plus all your other income, including tax-exempt interest, is $25,000 or less. For a married couple filing jointly the line is $32,000, and for married people filing separately who lived together at any time in the year it is $0 (IRS Publication 915). The 85% is the most of your benefits that can count as income, not a tax rate: the part that counts is taxed at your normal rate.

Pick your filing status and type your benefits for the year (box 5 of Form SSA-1099) and your other income. The calculator works through Publication 915’s worksheet line by line in your browser and sends nothing. It shows the taxable part of your benefits, not your whole tax bill.

Is Social Security taxable for you? The quick check

Your benefits may be taxable if half of them plus all your other income, including tax-exempt interest, is more than the base amount for your filing status (Publication 915, Worksheet A). To check, add half of your benefits for the year to your other income and to any tax-exempt interest, such as interest on municipal bonds. Your combined income is half of your benefits, plus your other income, plus any tax-exempt interest. If it is no more than the base amount, none of your benefits are taxable; if it is more, some may be.

Other income means everything taxable apart from the benefits: wages, pensions, interest, dividends, the taxable part of IRA and 401(k) withdrawals, and capital gains. Don’t reduce it by the exclusion for savings bond interest, employer adoption benefits, student loan interest or the foreign earned income exclusion. A married couple filing jointly adds both incomes and both sets of benefits, even if only one of them gets Social Security (Publication 915).

What are the base amounts?

They are $25,000, $32,000 or $0, depending on your filing status (Publication 915):

• $25,000 if you are single, head of household or a qualifying surviving spouse, or married filing separately and lived apart from your spouse all year.
• $32,000 if you are married filing jointly.
• $0 if you are married filing separately and lived with your spouse at any time in the year.

A second, higher line sits above each base amount: $34,000, or $44,000 for married filing jointly (Publication 915). Above it, up to 85% of your benefits can be taxable instead of up to 50%. For married people who file separately and lived together, both lines are $0, so the 85% rule applies from the first dollar.

$11,300 of your $24,000 in benefits (47.1%) would be taxable income on your federal return. Your combined income is $42,000.

How much is taxable: 50% or 85%?

It depends on how far your combined income is above the base amount, and it is never more than 85% of your benefits (Publication 915):

• At or below the base amount: none.
• Above the base amount but not above the second line: half of the amount over the base amount, but no more than half of your benefits.
• Above the second line: 85% of the amount over the second line, plus the smaller of half your benefits and $4,500 ($6,000 if married filing jointly), but no more than 85% of your benefits.

The law behind these steps is section 86 of the Internal Revenue Code, and the IRS worksheet follows it line by line. The map shows the whole route, from the worksheet through the two bands to the states.

1. Combined incomeHalf your benefits + other income + tax-exempt interest
2. Under $25,000($32,000 married filing jointly): none of it is taxable
3. Up to $34,000($44,000 jointly): up to 50% is taxable

5. Your stateMost states do not tax it; a few tax some of it

How does the IRS worksheet work?

Worksheet 1 in Publication 915 does the sums above in 19 lines; the same worksheet in the Form 1040 instructions does it in 18. The 2025 edition was the newest on irs.gov on October 29, 2026. In plain words:

1. Start with box 5 of your Form SSA-1099: your net benefits for the year. Use it as it is, without taking off the Medicare premiums withheld from your checks.
2. Take half of it.
3. Add your other income from Form 1040: wages, taxable interest, dividends, the taxable part of IRA and pension payments, capital gains and other income.
4. Add your tax-exempt interest and certain excluded income, such as foreign earned income.
5. Take off only certain adjustments from Schedule 1 (lines 11 to 20, 23 and 25 in 2025). Not the standard deduction, not itemized deductions and not student loan interest.
6. Compare what is left with your base amount. At or below it, stop: none of your benefits are taxable.
7. Split the amount over the base amount at $9,000 ($12,000 if married filing jointly). Half of the first part counts, but no more than half your benefits; 85% of the rest counts.
8. Add those two. The taxable part is that total or 85% of your benefits, whichever is smaller. It goes on Form 1040, line 6b.

How much is taxable on $24,000 of benefits and $20,000 of other income?

$3,500, for someone filing as single. Half of $24,000 is $12,000. Add $20,000 of pension and IRA income and the combined income is $32,000: $7,000 over the $25,000 base amount and under the $34,000 second line. Half of $7,000 is $3,500, which is less than half the benefits, so $3,500 is taxable (Publication 915, Worksheet 1). That is about 15% of the $24,000; the other $20,500 is not taxed at all.

How much is taxable for a couple with $40,000 of benefits and $50,000 of other income?

$29,800, for a couple filing jointly who also have $2,000 of tax-exempt bond interest. Half of $40,000 is $20,000. Add $50,000 and $2,000, and the combined income is $72,000, which is $40,000 over the $32,000 base amount. The first $12,000 of that counts at half, $6,000, which is less than half their benefits. The other $28,000 counts at 85%, $23,800. Together that is $29,800, under the cap of 85% of their benefits, $34,000 (Publication 915, Worksheet 1). So 74.5% of their benefits is taxable income, taxed at their normal rate.

With Social Security as your only income, your benefits generally aren’t taxable, and you probably don’t have to file a return, Publication 915 says.

Are the $25,000 and $32,000 limits adjusted for inflation?

No. The base amounts and the $34,000 and $44,000 lines are fixed dollar amounts written into section 86 of the tax code, and nothing in it raises them with prices. The IRS’s yearly list of inflation-adjusted amounts for 2026, Revenue Procedure 2025-32, does not include them. Benefits do rise with the cost-of-living increase, 3.6% for 2027 (SSA), so over time the same fixed lines catch more of retirees’ benefits. See COLA 2027.

Does the new $6,000 deduction for seniors make Social Security tax-free?

No. For tax years 2025 through 2028, people who are 65 or older by the end of the year can claim an extra deduction of $6,000 each, or $12,000 for a married couple filing jointly when both qualify (IRS). It comes from section 70103 of Public Law 119-21, signed on July 4, 2025. It is a deduction from income, not an exemption of benefits: the law did not change section 86, and the worksheet above is worked out the same way.

What the IRS says about it (Publication 6142):

• It comes on top of the extra standard deduction that people 65 or older already get: for 2026, $1,650 for each such person, or $2,050 if you are single or head of household (Rev. Proc. 2025-32).
• You can claim it whether you itemize or take the standard deduction.
• It shrinks by 6% of your modified adjusted gross income above $75,000, or $150,000 on a joint return (Schedule 1-A), which means it is gone at $175,000 ($250,000 joint).
• Married people must file jointly to get it, and the return must show a valid Social Security number for each person who claims it.

It can still lower your tax, because it lowers the income that is taxed. It just doesn’t change how much of your benefits counts as income: you claim it on Schedule 1-A and Form 1040 line 13b, after the taxable part of your benefits is worked out (Form 1040 instructions). The IRS also says it has no effect on whether a state taxes your benefits (IRS letter 2025-0006).

How do you have tax withheld from Social Security?

Fill in IRS Form W-4V and choose 7%, 10%, 12% or 22% of each payment; no other rate or dollar amount is allowed. Give it to SSA, not to the IRS. The form also says you can ask SSA online, on its tax withholding page. Your choice stays in effect until you change or stop it with a new W-4V. If you don’t have tax withheld, you may need to pay estimated tax during the year instead (Publication 915).

What if you got benefits for an earlier year in one payment?

You can choose to figure the taxable part of the back benefits with the earlier year’s income, and use that if it comes out lower: Publication 915 calls this the lump-sum election (Publication 915). Otherwise the whole lump sum counts in the year you receive it, in that year’s box 5, even if part of it was for an earlier year. To use the election, you tick the box on Form 1040, line 6c. That can matter for back pay after the WEP and GPO repeal.

Do states tax Social Security?

Most states do not tax Social Security benefits, and a handful do, each by its own rules. The federal rules do not decide it: a state can leave benefits out even when part of them is federally taxable. The state-by-state page shows which states tax benefits and how.

Questions people ask

Is Social Security taxable in 2027?

Yes, by the same rules as in 2025 and 2026: the $25,000 and $32,000 base amounts are fixed in the law and do not change with the year (Publication 915). The extra $6,000 deduction for people 65 or older runs through tax year 2028.

What percentage of Social Security is taxable?

None, up to 50% or up to 85% of your benefits, depending on your combined income and filing status, and never more than 85% (Publication 915). The taxable part is then taxed at your normal rate.

At what age is Social Security no longer taxable?

There is no such age: the same rules apply at 62 and at 92, and only your income changes the answer. Age matters for deductions such as the extra $6,000 for people 65 or older, which lower your tax but not the taxable part of your benefits.

Are Social Security disability benefits taxable?

Yes, by the same rules: Publication 915 counts retirement, survivor and disability benefits alike (Publication 915). Supplemental Security Income (SSI) payments are not taxable.

Do I have to file a tax return if I only get Social Security?

Probably not. If Social Security was your only income, your benefits generally aren’t taxable and you probably don’t have to file, Publication 915 says; with other income you may have to file even when none of your benefits are taxable.
