A Retired Couple Can Realize Nearly $100,000 in Gains This Year and Pay $0 Federal Tax. Most Sail Right Past It
The tax code contains a bracket most retired couples never notice, and missing it costs them thousands of dollars in completely avoidable federal taxes every single year.

If you own a taxable brokerage account and you’re retired filing jointly, the tax code has a gift sitting inside it that most couples walk right past: the 0% long-term capital gains bracket. Stack it on top of the 2026 standard deduction and you can sell appreciated stocks, funds, or ETFs and pay absolutely nothing in federal tax on the gain. The rate is zero.
The Reveal: A 0% Rate That Actually Exists
Long-term capital gains (assets held more than one year) are taxed on their own schedule, separate from ordinary income. The first band of that schedule is taxed at 0%, running from the first dollar of long-term gains up to the top of the 0% bracket. For a married couple filing jointly in 2026, that ceiling sits at $98,900 of taxable income. Layer the $32,200 standard deduction underneath it, and a retired couple with modest ordinary income can realize close to $100,000 of qualified gains in a single year and owe $0 in federal income tax on those gains.
The Proof
The rate structure lives in 26 U.S. Code §1(h), which sets the 0%, 15%, and 20% brackets for net capital gain. The 2026 dollar thresholds come from the IRS annual inflation adjustments published in Revenue Procedure 2025-32, released October 9, 2025. The $32,200 married-filing-jointly standard deduction is confirmed there, as is the $98,900 top of the 0% LTCG bracket for joint filers. Those figures incorporate changes from the One Big Beautiful Bill Act (OBBBA), which made the TCJA’s expanded standard deduction permanent and added a new $6,000 above-the-line deduction for taxpayers age 65 and older. That senior deduction, available for tax years 2025 through 2028, phases out for joint filers with modified adjusted gross income above $150,000 and disappears entirely at $250,000.
Who Qualifies, Who Doesn’t
You qualify if you file jointly, your total taxable income (ordinary income plus the gain you’re harvesting) lands at or below $98,900, and the assets you sell have been held longer than one year. Short-term gains do not count. Qualified dividends do count and share the same bracket. Single filers get a smaller version of the same deal: a $49,450 ceiling and the $16,100 standard deduction. You’re excluded if wages, pension income, IRA withdrawals, or taxable Social Security push your income past the ceiling before you even sell a share.
How to Use It in 2026
- Add up your projected 2026 ordinary income: pension, annuity payments, taxable Social Security, IRA and 401(k) withdrawals, interest, and short-term gains.
- Subtract the $32,200 standard deduction, plus the age-65 additional standard deduction of $1,650 per qualifying spouse if applicable, plus any OBBBA senior bonus deduction you’re eligible for, to arrive at taxable ordinary income.
- Find the gap between that number and the $98,900 ceiling. That gap is your tax-free harvest room.
- Sell long-term positions to realize gains up to (not over) that gap. If you still want to own the shares, buy them back the same day. The wash-sale rule blocks loss harvesting, but it does not apply to gains.
- Repeat every year. Each harvest resets your cost basis higher, shrinking the taxable gain your heirs or your future self will face.
The Catch
Three traps trip people up. First, the gain itself counts toward your income for the calculation, so a large sale can push part of the gain out of the 0% band and into the 15% band, where it gets taxed. Second, realized gains raise your Modified Adjusted Gross Income, which can trigger taxation of Social Security benefits and, two years later, IRMAA surcharges on Medicare Parts B and D. Third, states usually don’t honor the federal 0% rate. California, for one, taxes long-term gains as ordinary income.
Run the numbers in December, not April. Brokerages report realized gains for the full calendar year, and the 2.8% Social Security COLA that took effect in January 2026 has already pushed benefit checks higher for most retirees, quietly eating into their harvest headroom. Knowing exactly where you stand before year-end gives you the chance to act while there’s still time.
