You've worked for decades. You watched those FICA taxes vanish from every single paycheck since your first summer job. Now, the checks are finally hitting your bank account, and there's a nagging question: does the government get to dip into this money twice?
Honestly, it feels like a bit of a betrayal. But the short answer is: maybe. Whether you have to pay income tax on Social Security depends almost entirely on a weird little math problem the IRS calls "combined income." For about 40% of people, the answer is a frustrating "yes." For everyone else, the money is yours to keep.
The Math Nobody Told You About
The IRS doesn't just look at your Social Security check. They look at your whole "financial life," but with a twist. To figure out if you're on the hook, you have to calculate your combined income (sometimes called provisional income).
It works like this:
Take your Adjusted Gross Income (AGI). Add any nontaxable interest you earned (like from municipal bonds). Then—and this is the weird part—add exactly half of your Social Security benefits for the year.
If that total stays below a certain line, you're in the clear. If it goes over? Well, things get complicated.
The Thresholds (That Haven't Changed Since the 80s)
Here is where most people get tripped up. The income levels that trigger these taxes haven't been adjusted for inflation since 1984. Back then, $25,000 was a lot of money. Today? Not so much. Because these numbers are "frozen in time," more and more retirees find themselves paying taxes every year just because the cost of living went up.

If you file as an individual:
- Below $25,000: You pay $0 in federal tax on your benefits.
- $25,000 to $34,000: You might pay tax on up to 50% of your benefits.
- Above $34,000: Up to 85% of your benefits can be taxed.
If you’re married filing jointly:
- Below $32,000: No tax.
- $32,000 to $44,000: Up to 50% is taxable.
- Above $44,000: Up to 85% is taxable.
Basically, if you have a decent pension or a healthy 401(k) distribution, you’re almost certainly going to see the IRS take a bite out of your Social Security.
The "New" Rules for 2026
We're in 2026 now, and there's some good news for once. While the core thresholds I just mentioned haven't changed, a new "Senior Bonus Deduction" has kicked in that's actually helping people stay under those limits.
If you're 65 or older, you (and your spouse, if filing together) can claim an additional deduction of up to $6,000 each.

It’s not a "check in the mail" like some of those clickbait ads say. It’s a deduction. It lowers your taxable income. For a couple, that’s $12,000 of income the IRS ignores. This is huge because it can pull your "combined income" back down below the 50% or 85% trigger points.
Wait, Does My State Take a Cut Too?
This is where it gets really localized. Most states are actually pretty cool about this—they don't touch your Social Security. But as of 2026, there are still eight states that might take a piece of your check.
West Virginia finally dropped off the list this year. They finished their phase-out, so if you're in Morgantown or Charleston, you're officially done with state taxes on benefits.
The ones still taxing (to various degrees) are:
- Colorado
- Connecticut
- Minnesota
- Montana
- New Mexico
- Rhode Island
- Utah
- Vermont
Every one of these states has its own rules. For instance, in Colorado, if you're 65 or older, you can usually deduct the whole thing anyway. In Minnesota, the income limits are much more generous than the federal ones. If you live in one of these spots, don't panic—you probably won't pay the full state rate unless you're quite wealthy.

Can You Avoid the Tax Legally?
You can't change the law, but you can change how you take your money.
One of the smartest moves involves Roth IRAs. When you pull money out of a traditional IRA, it counts toward that "combined income" formula. But Roth IRA withdrawals? They’re invisible to that formula. If you can lean more on Roth income and less on traditional 401(k) or IRA income, you might keep your Social Security in the 0% tax bracket.
Another trick is Qualified Charitable Distributions (QCDs). If you're over 70.5, you can send money directly from your IRA to a charity. This satisfies your Required Minimum Distribution (RMD) but doesn't count as income.
Less income = lower "combined income" = less tax on your Social Security.
The Bottom Line
It’s a bit of a myth that everyone pays tax on Social Security. If it's your only source of income, you likely won't owe a dime. But if you've been a diligent saver and have other revenue streams, you need to plan for that 85% hit.
Your Immediate Next Steps:
- Calculate your "Combined Income" for this year using last year's tax return as a guide.
- Check the Senior Bonus Deduction rules to see if you qualify for that extra $6,000 or $12,000 off your taxable total.
- Adjust your withholding. If you find out you will owe, you can ask the Social Security Administration to withhold 7%, 10%, 12%, or 22% of your check so you don't get a massive bill next April.
