The 0% capital gains bracket for retirees in 2026

There is a tax rate of zero hiding in plain sight, and a lot of retirees walk right past it. In 2026, a married couple filing jointly can have up to $98,900 in taxable income and still pay nothing — 0% — on their long-term capital gains. For a single filer, the ceiling is $49,450. This isn’t a loophole or a gimmick. It’s the ordinary structure of the federal tax code, and the years between retirement and your first required withdrawals are often the best time to use it.

How can a 0% tax rate on profits be real?

Long-term capital gains — profit on an asset you’ve held more than one year — are taxed on their own schedule, separate from your wages, pension, and the taxable slice of Social Security. According to the IRS, in Topic no. 409 on capital gains and losses, the rate on a net long-term gain runs 0%, 15%, or 20%, and which one you pay depends entirely on your taxable income. Most people assume the answer is always 15%. It isn’t.

The piece that trips everyone up is something tax preparers call the stacking rule. Your ordinary income — pension, IRA withdrawals, the taxable part of Social Security, interest — gets counted first. It fills up the lower brackets. Then your long-term gains are layered on top of that pile, and only the portion of the gain that lands below the 0% ceiling escapes tax entirely.

So the question isn’t really “do I qualify.” It’s “how much room do I have left.” If your ordinary taxable income is already above $98,900 as a couple, your gains start at 15% and there’s no zero bracket left to use. If it’s well below that line, the gap is yours.

The 2026 income limits that decide your rate

The IRS adjusts these numbers for inflation every year, and 2026 brought a modest bump. The 0% ceiling for married couples rose from $96,700 in 2025 to $98,900, and the single ceiling moved from $48,350 to $49,450, as Kiplinger reported. Here is the full 2026 map.

Filing status 0% rate applies up to 15% rate 20% rate applies above
Single $49,450 $49,451 – $545,500 $545,500
Married filing jointly $98,900 $98,901 – $613,700 $613,700
Head of household $66,200 $66,201 – $579,600 $579,600

One number to keep straight: these are taxable income thresholds, not gross income. Taxable income is what’s left after your deductions come out. That distinction is exactly why retirees can stuff more under the line than the raw thresholds suggest.

Why retirees land in the sweet spot

Think about the shape of a typical retirement. You’ve stopped working, so the paychecks are gone. You may not have started Social Security yet, or you’ve claimed only a modest benefit. Required minimum distributions from traditional IRAs don’t begin until age 73. For a stretch of years — call them the gap years — your ordinary income can be unusually low, and that’s precisely when the 0% bracket has the most headroom.

Deductions widen the gap further. For 2026, the IRS set the standard deduction at $32,200 for married couples filing jointly and $16,100 for single filers. People 65 and older get an extra standard deduction on top — $1,650 per spouse for a married couple, $2,050 for someone single.

Then there’s the new one. The One Big Beautiful Bill Act created a temporary “senior bonus” deduction of $6,000 per person age 65 or older, in effect for tax years 2025 through 2028. The IRS confirms it phases out for higher earners, starting at $75,000 of modified adjusted gross income for singles and $150,000 for joint filers, and disappearing entirely at $95,000 and $190,000 respectively. Stack all of that together and a 66-year-old couple can shield close to $47,500 of income before a single dollar becomes taxable — which pushes the real-world gross income at which gains stay free quite a bit higher than $98,900.

A real example, run through the math

Say you and your spouse are both 66 and file jointly. Between a small pension and the taxable portion of Social Security, you have $50,000 of ordinary income for the year. Your deductions — the $32,200 standard deduction, $3,300 in extra age-65 deductions, and $12,000 from the senior bonus — total $47,500.

That leaves $2,500 of ordinary taxable income. Now the gains stack on top.

The 0% bracket runs to $98,900, and you’ve used only $2,500 of it, so you have $96,400 of room left. That means you could sell appreciated stock or a mutual fund and realize up to roughly $96,400 of long-term gain — and owe zero federal tax on it.

Zero, on nearly a hundred thousand dollars of gain. This move has a name: gain harvesting. You sell a winner purely to lock in the gain at 0%, then you’re free to buy it right back immediately (the wash-sale rule that bites loss harvesting doesn’t apply to gains). Your cost basis resets higher, so a future sale starts from a bigger number. Wouldn’t you rather reset that basis for free now than pay 15% on it later?

What can quietly go wrong

The gain itself counts as income for almost everything else on your return, even when its own rate is 0%. That’s the catch people miss. Realizing a big gain raises your adjusted gross income, and a higher AGI can drag more of your Social Security into the taxable column and can lift your Medicare premiums two years down the road through the income surcharge known as IRMAA — see our explainer on the 2026 IRMAA income thresholds before you sell anything large.

There’s also the stacking trap in reverse. Only the gain that fits under $98,900 gets the zero rate. Realize more than your remaining room and the overage spills into the 15% bracket — sometimes the very same sale is part 0% and part 15%. And if extra income pushes your MAGI past $150,000, you start losing that $6,000-per-person senior deduction, which can cost you more than the tax you saved. None of this makes the strategy bad. It makes it something to size carefully rather than max out blindly.

This is general information, not personal tax advice — run your specific numbers with a CPA or fee-only financial planner before you pull the trigger.

How to actually do this

Start by estimating your taxable income for the year before any gains: pension, withdrawals, interest, the taxable share of Social Security, minus your deductions. Subtract that from $49,450 (single) or $98,900 (joint). Whatever’s left is the gain you can harvest at 0%. The free IRS Tax Withholding Estimator and a good tax-software projection both help you model it before year-end, when you still have time to act.

The same gap years that make gain harvesting work are also when Roth conversions after retirement make sense — but the two strategies compete for the same bracket space, so you generally pick one per year rather than doing both. Whichever you choose, do it before December 31. Capital gains are realized in the year you sell, and there’s no extension.

What to remember

The 0% long-term capital gains bracket is a permanent feature of the tax code, not a one-time break, and for 2026 it tops out at $49,450 of taxable income for singles and $98,900 for couples. Because ordinary income fills the brackets first and deductions shrink your taxable income, retirees in their low-income gap years often have real room underneath that line. Use it deliberately: estimate your remaining headroom, watch the ripple effects on Social Security taxation and Medicare premiums, and harvest only as much gain as fits.
