Is your Social Security being taxed?

You've seen the headlines: "No more tax on Social Security." That isn't quite what happened, and believing it costs people money at tax time. Up to 85% of your benefit can count as taxable income, the rules didn't change in 2025, and most retirees don't know which side of the line they're on. Below: what the law actually did, how to work out how much of your benefit is taxable, who pays nothing, who gets hit, and the legal moves that bring the number down.

Did the 2025 law make Social Security tax-free?

No, and this is where most of the confusion lives. The 2025 law, the "One Big Beautiful Bill," created a temporary $6,000 senior deduction, or $12,000 for a couple where both are 65 or older. It lowers your overall tax bill and you should claim it. But a deduction isn't a repeal. It didn't change how Social Security itself is taxed. The 0%, 50% and 85% rules below work exactly as they did before. More on it in the $6,000 senior deduction. Source: IRS, the enhanced deduction for seniors.

How much of your Social Security is taxable in 2026?

At the federal level, anywhere from none of your benefit to 85% of it can count as taxable income. Read that twice. It isn't 85% in tax. It's up to 85% of the benefit added to your taxable income, then taxed at your normal rate. And however high your income climbs, no more than 85% ever counts. At least 15% of your benefit stays tax-free, even for a millionaire. Source: SSA, taxes on benefits, and IRS Publication 915.

One point of confusion worth clearing first, because it sends people to the wrong page. The 2025 Social Security tax limit people search for is usually the wage base: the ceiling on earnings that pay Social Security tax while you work. That is a different rule from this one, and it has nothing to do with whether your benefit gets taxed after you retire. There is no ceiling on the benefit side. What decides it is the combined-income formula below.

One note. This is the federal rule. A small and shrinking number of states tax Social Security as well, so check yours. For most people the federal rule decides it.

People ask what percent Social Security tax they'll pay, and the honest answer is that there isn't a Social Security tax rate on benefits at all. Up to 85% of the benefit joins your taxable income, then your ordinary bracket does the work. So is Social Security taxable in 2026? For some people, yes, on the same 0/50/85 rules as last year. How much of your Social Security is taxable in 2026 comes down to one figure, and it isn't your benefit.

At what age does Social Security stop being taxed?

It doesn't. There's no birthday that switches this off, and that surprises people more than anything else on this page. Whether your benefit is taxed depends on your income, not your age, so Social Security is still taxable after age 70, after 75, and for as long as your combined income sits above the thresholds below. The rule that ends at an age is the one about earning while you collect, and that's a different rule entirely: the earnings test stops at your full retirement age. Nothing about the tax stops, ever.

What does change with age is a deduction, not the tax. From 65 you get an extra standard deduction, and for tax years 2025 through 2028 the senior deduction on top of it. Both lower your overall bill. Neither changes how much of your benefit counts as taxable income.

The one number that decides it

What puts you at 0%, 50% or 85% is a single number the IRS calls your combined income. Some people call it provisional income. Same thing.

Social Security by itself usually isn't taxed. Your other income does the pushing: IRA and 401(k) withdrawals, a pension, wages, interest. Source: SSA, taxes on benefits, and IRS Publication 915.

The 2026 thresholds

A worked example (single)

Say you're single, your Social Security is $24,000 a year, and you pull $30,000 from a traditional IRA. Half your benefit is $12,000. Add the $30,000 and your combined income is $42,000. Run it through the thresholds:

• The first $25,000: nothing.
• The $9,000 between $25,000 and $34,000: counts at 50%, so $4,500.
• The $8,000 above $34,000: counts at 85%, so about $6,800.

Add those and roughly $11,000 of your $24,000 benefit is taxable. That's a simplified illustration of the shape. Your exact figure comes from the worksheet in IRS Publication 915, or from your tax software. Notice what happens if you take the IRA withdrawal away and live on Social Security alone: almost none of it gets taxed. The other income pulls your benefit in. Source: IRS, Pub. 915, worksheet 1.

A worked example (married)

Same engine, bigger thresholds. You're married, your combined Social Security is $40,000, and you take $35,000 from a pension or IRA. Half your benefit is $20,000, so your combined income is $55,000. The first $32,000 counts for nothing. The next $12,000 counts at 50%. The $11,000 above $44,000 counts at 85%. Add it up and roughly $15,000 of your $40,000 benefit is taxable. Source: IRS, Pub. 915, worksheet 1.

Why it quietly gets worse every year

Those thresholds, $25,000 and $32,000 and $34,000 and $44,000, haven't been adjusted since the 1980s and 90s. Nothing indexes them to inflation. Your benefit rises. Your withdrawals rise. Groceries rise. The lines that decide your tax stay exactly where they were. So every year a few more middle-income retirees cross over and start paying tax on benefits that used to be free of it. No new law is doing that. The old one is standing still. Source: IRS, Pub. 915 (the base amounts are fixed in statute, not indexed).

Who it hits, and who it misses

The honest part, so you don't stress over nothing:

• Mostly Social Security, little else. Good chance you pay zero tax on your benefit, and the senior deduction won't change much, because there was little to tax in the first place.
• The middle. Enough from a pension or IRA to cross the thresholds, nowhere near wealthy. This group gets hit hardest.
• High earners. Sitting at the 85% cap. Remember that 15% stays tax-free.

Know which group you're in before you plan, not after.

The survivor's penalty

Almost nobody sees this one coming. When one spouse dies, the survivor usually files as single the very next year, and the single thresholds sit far lower: $25,000 and $34,000 instead of $32,000 and $44,000. So the survivor has less income, because they keep the larger Social Security check and lose the smaller one, and yet more of it becomes taxable, because the single thresholds now measure them. Their standard deduction roughly halves on top of that. People call it the widow's penalty. The tax bill goes up at the exact moment the income goes down. If you're a couple, plan for it together now, while you both can.

3 legal moves that lower it

• The $6,000 senior deduction. If you're 65 or older and you qualify, claim it. It lowers your overall taxable income.
• Roth conversion timing, which cuts both ways. A big conversion in a year you're already drawing Social Security backfires. It raises your combined income, so more of your benefit gets taxed and you can lose part of the senior deduction. Advisors call that the tax torpedo. Turn it around and convert in a low-income year, retired but not yet drawing Social Security or required withdrawals, and you fill the low brackets cheaply while shrinking income that would have been taxed later. Same tool, opposite result. Run it past a tax pro first.
• Qualified Charitable Distribution. If you're old enough to take required withdrawals, send some straight to charity. It doesn't count as income, so it lowers your combined income, shrinks the tax on your Social Security, and can win back part of the senior deduction. Act before December 31, not in April.

What to do

• Work out your combined income, half your Social Security plus your other income, and see which side of the thresholds you land on.
• If someone prepares your taxes, ask point-blank: how much of my Social Security is taxable this year, and was the senior deduction applied?
• If you're near a threshold, look at your withdrawals and charitable giving before December 31.
