At the federal level, the income limit for no tax on Social Security is $25,000 in combined income if you file as single, head of household, or qualifying surviving spouse, and $32,000 if you are married filing jointly. Stay below those numbers and none of your benefits are taxable. Cross them and a portion of your benefits gets added to your taxable income, though a new senior deduction passed in 2025 means most retirees still end up owing nothing.1Social Security Administration.

The Federal Thresholds by Filing Status
The tax code sets three tiers for each filing status. The bottom tier is the income limit for zero tax. The middle and upper tiers determine how much of your benefit gets pulled into taxable income once you pass the limit.2Office of the Law Revision Counsel. 26 USC 86 – Social Security and Tier 1 Railroad Retirement Benefits
Single, Head of Household, or Qualifying Surviving Spouse
- Combined income below $25,000: none of your benefits are taxable.
- $25,000 to $34,000: up to 50 percent of your benefits may be included in taxable income.
- Above $34,000: up to 85 percent of your benefits may be included in taxable income.
Married Filing Jointly
- Combined income below $32,000: no benefits are taxable.
- $32,000 to $44,000: up to 50 percent of benefits may be included.
- Above $44,000: up to 85 percent of benefits may be included.
Married Filing Separately
If you are married, file a separate return, and lived with your spouse at any point during the year, the income limit is $0. From the first dollar of combined income, up to 85 percent of your benefits can be treated as taxable.3Internal Revenue Service. Social Security Income There is no zero-tax zone and no 50 percent tier. One narrow exception: if you and your spouse lived apart for the entire tax year, you use the $25,000 single-filer threshold instead.4Internal Revenue Service. Publication 915 – Social Security and Equivalent Railroad Retirement Benefits
These dollar figures come straight from 26 U.S.C. § 86 and are not indexed for inflation. They have been the same since the 1984 base amounts were set and the 85 percent tier was added in 1993.5Social Security Administration. Social Security Related Legislation in 1993 Because wages, pensions, and investment returns have all risen over the decades while the thresholds haven’t, more beneficiaries cross them each year.
What Counts as Combined Income
The number that decides your tier is called combined income (also called provisional income), and it is built in three steps.
Start with your modified adjusted gross income. That includes wages, pensions, distributions from traditional retirement accounts, investment gains, rental income, and most other items on your tax return. Then add any tax-exempt interest you earned during the year. Municipal bond interest is the most common example, and tax-exempt original issue discount from bonds acquired after 2016 also counts.6Internal Revenue Service. Interest Received Finally, add one-half of your total Social Security benefits for the year, which appears in Box 5 of the SSA-1099 mailed each January.3Internal Revenue Service. Social Security Income
The tax-exempt interest step catches people off guard. That interest doesn’t show up as taxable income anywhere else on your return, yet it pushes up the number that determines whether your Social Security gets taxed. If you’re near a threshold, a large municipal bond portfolio can quietly move you over.
For married couples filing jointly, all income sources for both spouses, and both benefit amounts, feed a single combined income calculation. If one spouse works part-time or draws a pension, that income pools with both benefits, which can put a couple over $32,000 or $44,000 unexpectedly.
“Up to 85 Percent Taxable” Doesn’t Mean an 85 Percent Tax
This is the most common misreading of the rules. When you hear that up to 85 percent of your benefits are taxable, it does not mean the government takes 85 percent of your check. It means 85 percent of your benefit amount gets added to your other taxable income, and you pay your regular income tax rate on that combined total.7Internal Revenue Service. IRS Reminds Taxpayers Their Social Security Benefits May Be Taxable The other 15 percent is always tax-free, no matter how high your income climbs.
So a retiree in the 12 percent bracket whose benefits are 85 percent taxable pays roughly 12 percent tax on 85 percent of their benefits, not 85 percent of them.
Why Most Retirees Now Owe Nothing Even Above the Limit
The One Big Beautiful Bill, signed into law in 2025, added an enhanced standard deduction for Americans aged 65 and older: $6,000 for a single filer and $12,000 for a married couple filing jointly when both spouses are 65 or older.8U.S. House of Representatives. Enhanced Deduction for Seniors – Frequently Asked Questions For 2026, that brings the total standard deduction to $23,750 for a single senior and $47,500 for a qualifying married couple.
The combined income formula still decides whether any of your benefits are technically taxable. But even when some portion counts as taxable income, the enlarged deduction often wipes out the resulting tax entirely. The Social Security Administration estimates that nearly 90 percent of beneficiaries will effectively owe no federal income tax on their benefits under the new deduction.1Social Security Administration. Social Security Applauds Passage of Legislation Providing Historic Tax Relief
The retirees still likely to owe are those with meaningful income from pensions, investments, rental properties, or continued work. For that group, the $25,000, $32,000, and $44,000 thresholds remain the numbers to watch.
Ways to Stay Under the Threshold
Because combined income drives everything, the practical question is which income sources feed the formula and which don’t.
Roth IRA Withdrawals
Qualified distributions from a Roth IRA are not part of your adjusted gross income, so they never enter the combined income formula. Pulling $10,000 from a Roth adds nothing to combined income; pulling the same $10,000 from a traditional IRA adds the full amount. For retirees near a threshold, that difference can decide whether benefits stay tax-free. The trade-off is that Roth conversions done before retirement are taxable in the year of conversion, so the planning window usually opens in your early sixties before you claim benefits.
Qualified Charitable Distributions
If you’re 70½ or older and taking required minimum distributions from a traditional IRA, donating directly from the IRA to a qualified charity keeps that distribution out of your adjusted gross income. It still satisfies part or all of your RMD, but it doesn’t lift your combined income. Each person can direct up to $111,000 this way in 2026.
Managing Capital Gains
Selling investments at a gain in a single year can spike combined income and push you into a higher tier. Spreading sales across tax years, harvesting losses to offset gains, and holding tax-efficient funds that generate fewer capital gains distributions all keep the number lower. Every dollar of investment income counts the same as a dollar of wage income in this formula.
State Taxes Are a Separate Question
The federal income limit tells you nothing about your state. Most states either have no income tax or fully exempt Social Security benefits. As of 2026, roughly eight states still tax benefits to some degree: Colorado, Connecticut, Minnesota, Montana, New Mexico, Rhode Island, Utah, and Vermont. West Virginia completed its phase-out and fully exempts benefits starting with 2026 returns.
States that do tax benefits typically offer their own exemptions based on age or income. Some follow the federal thresholds; others set independent limits. You may owe federal tax on a portion of benefits while owing nothing at the state level, or, less commonly, the reverse. Your state’s department of revenue publishes the specific rules that apply.
