Pay 0% Tax on Your 2026 Stock Gains — Here's How

2026 Capital Gains Tax Brackets: 0%, 15%, or 20%?

FINANCE

Married couples can sell appreciated stock on $80,000 of income and pay $0 federal tax — but one bigger sale triggers 15%. The rule that decides which is "stacking," and almost no one shows it.

A married couple with $80,000 of taxable income can sell appreciated stock and pay exactly $0 in federal tax on the gain. Sell a bigger slice — say $30,000 of it — and part of that same sale suddenly gets taxed at 15%. The difference isn't luck, and it isn't a loophole. It's a mechanical ordering rule called "stacking" that almost no article bothers to show you.

Here's what most coverage of the 2026 capital gains brackets gets wrong: it hands you a rate table and stops. But the table doesn't tell you the one thing that actually decides your bill — where your long-term gains land on top of your other income. Get the ordering right and you can legally realize tens of thousands of dollars in gains at a 0% federal rate. Get it wrong and you overpay, or worse, trip an inflation-frozen surtax you didn't budget for.

Key Takeaways

  • The 2026 long-term capital gains rates didn't change — they're still 0%, 15%, and 20%. Only the income thresholds moved up with inflation, set by IRS Revenue Procedure 2025-32 (released October 2025).
  • A single filer pays 0% on long-term gains as long as total taxable income (including the gains) stays at or below $49,450 in 2026; for married couples filing jointly, the ceiling is $98,900 (IRS Rev. Proc. 2025-32).
  • Capital gains "stack" on top of your ordinary income. Ordinary income fills the brackets first, then your gains fill whatever room is left — which is why one stock sale can be taxed at two rates at once.
  • The 3.8% Net Investment Income Tax kicks in above $200,000 (single) or $250,000 (married filing jointly) of modified adjusted gross income — and those thresholds have never been adjusted for inflation since 2013 (IRS Topic No. 559).
  • Short-term gains (assets held one year or less) get no preferential rate — they're taxed as ordinary income, up to 37% (IRS Topic No. 409).

This is informational, not financial advice.

How We Analyzed This

This study pulls the 2026 long-term capital gains thresholds from the primary federal source — IRS Revenue Procedure 2025-32, the annual inflation-adjustment document the IRS released in October 2025. We cross-checked the four filing-status brackets against secondary tax-practitioner and financial-press summaries (Kiplinger, CNBC, the Tax Foundation) to confirm the figures and to surface a small discrepancy circulating online, which we reconcile below.

We compared the 2026 numbers against the 2025 thresholds published in IRS Rev. Proc. 2024-40 to measure the year-over-year inflation shift. For the surtax and holding-period rules, we relied on IRS Topic No. 559 (Net Investment Income Tax) and IRS Topic No. 409 (Capital Gains and Losses). Every worked example below is built from published IRS thresholds only — no hands-on tax preparation, no proprietary calculator. Where sources disagreed on a single figure, we defaulted to the value stated in the Revenue Procedure itself.

What the Data Shows

Long-term capital gains — profits on assets you held longer than one year — are taxed on a separate, gentler schedule than your paycheck. The 2026 thresholds, based on taxable income (gross income minus your deductions), break down like this:

Filing status 0% rate 15% rate 20% rate
Single Up to $49,450 $49,451 – $545,500 Above $545,500
Married filing jointly Up to $98,900 $98,901 – $613,700 Above $613,700
Head of household Up to $66,200 $66,201 – $579,600 Above $579,600
Married filing separately Up to $49,450 $49,451 – $306,850 Above $306,850

Source: IRS Rev. Proc. 2025-32.

The headline finding: the rate structure held steady at 0/15/20% for 2026 — only the dollar breakpoints climbed with inflation, by roughly 2.3% over 2025 (Kiplinger / Tax Foundation). That sounds trivial. It isn't. Each dollar the 0% ceiling rises is another dollar of gains a strategic filer can harvest tax-free.

Filing status 2025 0% ceiling 2026 0% ceiling Increase
Single $48,350 $49,450 +$1,100
Married filing jointly $96,700 $98,900 +$2,200

2025 figures per IRS Rev. Proc. 2024-40; 2026 figures per IRS Rev. Proc. 2025-32.

For a married couple, that $2,200 bump means an extra $2,200 of appreciated stock can be sold at 0% in 2026 versus 2025 — a $330 federal tax saving on that slice alone if it would otherwise have been taxed at 15%. Small numbers compound when you repeat the move every year.

The Stacking Rule, Step by Step

This is the mechanic that decides your rate, and it's the one competitors skip. Long-term capital gains don't get their own private bucket. They pile on top of your ordinary income, and the combined total is what's measured against the thresholds above.

Think of your taxable income as water filling a tall glass. Your ordinary income — wages, interest, retirement distributions — pours in first and settles at the bottom. Your long-term gains float on top. The rate on those gains depends entirely on which band they're floating in once everything else is already in the glass.

Work a concrete case. A married couple has $70,000 of ordinary taxable income (after deductions) and wants to sell stock carrying a $40,000 long-term gain.

  1. The $70,000 of ordinary income fills the bottom of the glass first.
  2. The 0% band for joint filers runs up to $98,900 in taxable income. Between $70,000 and $98,900 there's $28,900 of room left in the 0% band.
  3. The first $28,900 of the gain floats into that room and is taxed at 0%.
  4. The remaining $11,100 of the gain spills past $98,900 into the 15% band and is taxed at 15% — $1,665.

One sale. Two rates. The couple's $40,000 gain generated exactly $1,665 in federal tax, an effective rate of about 4.2% — not the flat 15% a rate table would have led them to expect.

When One Sale Gets Taxed at Two Rates

That split is not an edge case — it's the norm for anyone near a threshold, and it's almost universally glossed over. The IRS doesn't apply a single rate to your whole gain based on your total income. It slices the gain at the exact dollar where one band ends and the next begins.

Portion of the $40,000 gain Band it lands in Rate Tax
First $28,900 Fills the rest of the 0% band 0% $0
Next $11,100 Spills into the 15% band 15% $1,665
Total $1,665

The practical lesson: your capital gain is itself income that can push you out of the 0% bracket. Selling more doesn't retroactively tax the whole gain at a higher rate — only the dollars that spill over get the higher rate. That's the opposite of how many people fear it works, and it's why "I'll owe 15% on everything if I sell" is usually wrong.

The 0% Harvesting Playbook

Once you understand stacking, tax-gain harvesting becomes arithmetic. The goal: realize gains up to — but not past — the top of your 0% band, resetting your cost basis higher without paying a dime in federal tax.

The formula is simple:

0% headroom = your filing-status 0% ceiling − your ordinary taxable income

A married couple with $60,000 of ordinary taxable income in 2026 has $98,900 − $60,000 = $38,900 of headroom. They can sell long-term holdings with up to $38,900 in gains, pay $0 federal tax, and immediately rebuy the same position to lock in a higher basis. (Unlike tax-loss harvesting, gain harvesting isn't subject to the wash-sale rule, which only disallows losses — you can repurchase instantly. Losses, by contrast, are barred if you buy a substantially identical security within 30 days before or after the sale — a 61-day window — per IRS Publication 550.)

Do this in a low-income year — early retirement, a sabbatical, a gap between jobs — and you can walk decades of appreciation up to the 0% ceiling one annual bite at a time. The single-filer version uses the $49,450 ceiling; head of household uses $66,200.

One caution the harvesting crowd underplays: the gain counts as income for other means-tested thresholds even when it's taxed at 0% federally. A big realized gain can raise the income figures that drive Medicare IRMAA premium surcharges, ACA marketplace subsidy eligibility, and the taxable share of Social Security benefits. Zero capital gains tax doesn't always mean zero cost.

The 3.8% Surtax Nobody Budgets For

Above the capital gains brackets sits a separate charge that trips up higher earners: the Net Investment Income Tax (NIIT), a 3.8% surtax on investment income — including capital gains — that applies once your modified adjusted gross income clears a threshold (IRS Topic No. 559).

Filing status NIIT threshold (MAGI)
Single / head of household $200,000
Married filing jointly $250,000
Married filing separately $125,000

Source: IRS Topic No. 559.

Here's the detail worth flagging: those thresholds are not indexed for inflation. They've been frozen since the tax took effect in 2013 — the thresholds are fixed by statute (Internal Revenue Code §1411), which contains no inflation adjustment. Every year of inflation quietly pulls more households over the line without Congress lifting a finger. Stack the NIIT on top of the 20% rate and the effective federal ceiling on long-term gains reaches 23.8% for top earners (Schwab).

Short-Term Gains and the Special-Rate Assets

Everything above assumes a holding period longer than one year. Sell sooner and the preferential rates vanish — short-term gains are taxed as ordinary income, at rates running up to 37% in 2026 (IRS Topic No. 409). Holding a winning position for even one extra day past the one-year mark can be the difference between the 37% ordinary rate and the 20% long-term rate.

And not every long-term gain gets the 0/15/20% treatment. A few asset classes carry their own ceilings:

Asset type Maximum federal rate
Most long-term gains (stocks, funds, most crypto held >1 yr) 20%
Collectibles — art, coins, precious metals 28%
Unrecaptured Section 1250 gain — real estate depreciation 25%
Short-term gains (held one year or less) Up to 37% (ordinary rates)

Sources: IRS Topic No. 409, IRS Publication 550.

That real estate line surprises people. When you sell a rental property, the portion of your gain that represents depreciation you previously deducted — "unrecaptured Section 1250 gain" — is taxed at up to 25%, not the 15% or 20% you might expect for the rest of the profit (IRS Publication 550). Collectibles get an even stiffer 28% cap.

Why the Numbers Online Don't Match

Search "2026 capital gains 0% bracket" and you'll find some sources listing $48,350 for single filers and others saying $49,450. Both are technically real numbers — they're just different tax years. $48,350 is the 2025 single-filer 0% ceiling; $49,450 is the 2026 figure from Rev. Proc. 2025-32. Sites that haven't updated since last year, or that mislabel the year, are the source of the confusion.

There's also a narrower discrepancy on the single-filer 20% breakpoint: most sources cite $545,500 (matching the Revenue Procedure), while a handful list $545,050. The figure stated in IRS Rev. Proc. 2025-32 is $545,500, so that's the one we use. When a tax number online doesn't match, check two things: the tax year it's labeled for, and whether it traces back to the IRS Revenue Procedure or to a secondary site's transcription.

Frequently Asked Questions

Does the capital gain itself count as income that can push me out of the 0% bracket?

Yes. Your long-term gain is added to your other taxable income, and the combined total is what's measured against the thresholds. A large gain can lift you out of the 0% band and into the 15% band — but only the dollars that spill over the ceiling get the higher rate (IRS Topic No. 409).

Are the 2026 capital gains rates higher than 2025?

No. The rates are unchanged at 0%, 15%, and 20% — only the income thresholds rose with inflation for 2026. A larger gain can still land in a higher bracket, but the rate schedule itself is identical to 2025 (IRS Rev. Proc. 2025-32) - unchanged at 0%, 15%, and 20%. Only the income thresholds rose, by roughly 2.3%–2.8% for inflation (Kiplinger / Tax Foundation). More of your income now fits under each rate ceiling than it did in 2025.

How long do I have to hold an asset to get the long-term rate?

More than one year. Assets held one year or less are "short-term" and taxed at your ordinary income rate — up to 37% — with no preferential treatment (IRS Topic No. 409).

What is the highest possible federal rate on long-term gains?

23.8% — the 20% top capital gains rate plus the 3.8% Net Investment Income Tax for filers above the MAGI thresholds (IRS Topic No. 559; Schwab).

Is crypto taxed at the capital gains rates?

Cryptocurrency held longer than one year is generally taxed under the same 0/15/20% long-term structure as stocks; crypto held one year or less is taxed as a short-term gain at ordinary rates (IRS Topic No. 409).
