The 0% Capital Gains Bracket Is Real — Here’s Where It Ends in 2026

The short answer

For 2026, long-term capital gains are taxed at 0 percent as long as taxable income — including the gain itself — stays under $98,900 for a married couple filing jointly ($49,450 single). Ordinary income stacks first; gains stack on top; only what fits under the line rides at 0. Add the $32,200 standard deduction and a couple can gross $131,100 before a gain dollar is taxed — but the gain still raises AGI, which Social Security taxation and Medicare IRMAA both key on. The arithmetic is below. This is an educational summary, not advice.

A retired couple sells a mutual fund they have held for twenty years — $35,000 of gain — and braces for the tax bill. In April, the gain adds exactly zero dollars to their federal tax. Nothing was sheltered, timed, or engineered. The gain simply landed in the 0 percent capital gains bracket, which sits at the bottom of the rate schedule the same way the 10 percent bracket sits at the bottom of the ordinary one. It is one of the least-used numbers in the tax code, mostly because working households rarely qualify — and retired households often do without realizing it.

Where Does the 0% Bracket End in 2026?

Long-term capital gains — assets held more than one year — have their own rate schedule: 0, 15, and 20 percent. For 2026, the 0 percent rate applies as long as taxable income, including the gain itself, stays under these lines:

Filing Status0% Applies Up To15% Applies Up To20% Above
Married filing jointly$98,900$613,700$613,700
Single$49,450$545,500$545,500

(Taxable-income thresholds per IRS Rev. Proc. 2025-32, §4.03. The rate mechanics are described in IRS Topic No. 409.)

Those are taxable income figures — income after the standard deduction. A married couple taking the 2026 standard deduction of $32,200 can therefore collect $98,900 + $32,200 = $131,100 of gross income before a single long-term gain dollar is taxed — more if they are 65 or older and the additional age-based deductions apply. Qualified dividends ride the same schedule, so the ordinary dividends a taxable brokerage account throws off each year are often sitting in the 0 percent bracket already.

Ordinary Income Goes First, Gains Stack on Top

The mechanic that decides everything: ordinary income fills the schedule first, and long-term gains stack on top of it. The gain is taxed at 0 percent only to the extent it fits in the room left under the threshold.

Take a retired couple with $60,000 of taxable ordinary income — pension, IRA withdrawals, interest — who sell the fund with the $35,000 long-term gain:

  • The gain stacks from $60,000 up to $95,000 of taxable income.
  • $95,000 is under the $98,900 line, so all $35,000 is taxed at 0 percent. Federal tax on the sale: $0.

Now run the same sale with $70,000 of ordinary income:

  • Room under the line: $98,900 − $70,000 = $28,900 taxed at 0 percent.
  • The remaining $35,000 − $28,900 = $6,100 crosses the line and is taxed at 15 percent: $915.

Same asset, same gain, same year — the tax bill is decided by how much room the ordinary income left underneath it. That is why the sequencing of withdrawals and sales, not just the amounts, sets the bill.

Why Do Retirees See This Bracket More Than Workers?

A household earning two salaries rarely has taxable income under $98,900 in the first place. Retirement changes the arithmetic. In the years after the paychecks stop — especially before Social Security and required minimum distributions begin — ordinary income can fall to a fraction of its working level, and room opens under the line. The same brokerage position that would have been taxed at 15 percent during the working years can pass through the 0 percent bracket in the years between.

Two mechanics are worth knowing plainly:

  • Realizing a gain resets the basis. Selling a long-held position and repurchasing it recognizes the gain at today's rate and restarts the cost basis at today's price. The wash-sale rule — the 30-days-before-or-after repurchase restriction — applies to realized losses, not gains. (IRS Pub. 550)
  • The bracket refills every year. The threshold is an annual test. A gain too large for one year's room can, mechanically, be realized across several years' worth of room instead. How that interacts with a household's other income is exactly the kind of sequencing question the withdrawal-order guide walks through.

What the 0% Rate Does Not Do

The 0 percent bracket removes the capital gains tax — it does not remove the income. A harvested gain still lands in adjusted gross income in full, and AGI is the number other parts of the retirement tax system key on:

  • Social Security taxation. The gain raises provisional income dollar for dollar, which can pull benefit dollars into the taxable column even while the gain itself is taxed at zero. The mechanics are the tax torpedo.
  • Medicare premiums. IRMAA surcharges test AGI (plus tax-exempt interest) with a two-year lookback — a large 2026 gain shows up in 2028 premiums, and the $218,000 cliff has no rounding grace.
  • State tax. Most states with an income tax treat capital gains as ordinary income; a 0 percent federal rate does not make the gain free everywhere — Texas has no state income tax, but many other retirement destinations do.

And the trap inside the mechanic itself: the gain counts toward the same threshold it is being tested against. A gain large enough to fill the room keeps stacking — the excess is taxed at 15 percent, not zero. The bracket is a container, not a switch.

Frequently Asked Questions

Q: Where does the 0% capital gains bracket end in 2026?

At $98,900 of taxable income for married couples filing jointly and $49,450 for single filers, per IRS Rev. Proc. 2025-32. Taxable income means income after the standard deduction — $32,200 for a couple, $16,100 single — and it includes the gain being tested.

Q: Does the gain itself count toward the threshold?

Yes. Ordinary income stacks first, then the gain stacks on top; only the portion that fits under the line is taxed at 0 percent. Anything above the line is taxed at 15 percent.

Q: Do qualified dividends get the 0% rate too?

Yes — qualified dividends use the same 0/15/20 rate schedule and the same 2026 thresholds as long-term capital gains.

Q: If the federal rate is 0%, is the gain really tax-free?

Federally, yes — on the portion inside the bracket. But the gain still enters adjusted gross income, where it can raise the taxable share of Social Security and, with a two-year lag, Medicare IRMAA premiums. Most states with an income tax also tax the gain at their own rates.
