Capital Gains Tax Changes 2026: New Brackets, Rates & What You Need to Know
Every year, the IRS adjusts tax brackets and thresholds for inflation — and 2026 is no exception. If you're selling investments, real estate, or other assets this year, understanding exactly what changed (and what didn't) is critical for minimizing your federal tax bill. This comprehensive guide covers every capital gains tax change for 2026, compares the new brackets side-by-side with 2025, and provides actionable planning strategies based on IRS Revenue Procedure 2025-32.
The headline: capital gains tax rates did not increase for 2026. The three-tier structure of 0%, 15%, and 20% remains intact. What did change are the income thresholds that determine which rate you pay — all adjusted upward by approximately 2.3% — along with a higher standard deduction that indirectly expands the 0% bracket for many taxpayers. Meanwhile, the 3.8% Net Investment Income Tax (NIIT) thresholds remain frozen at their 2013 levels, pulling more investors into the surtax each year.
Whether you're a retiree harvesting gains in the 0% bracket, a middle-income investor planning year-end sales, or a high earner navigating NIIT, this guide will show you exactly where you stand for 2026 and how to use the new thresholds to your advantage.

1. What Changed for 2026 Capital Gains Tax
The IRS released Revenue Procedure 2025-32 in late 2025, establishing the inflation-adjusted tax parameters for tax year 2026. Here is a concise summary of every change relevant to capital gains:
- Long-term capital gains bracket thresholds increased ~2.3%. The 0% bracket now covers taxable income up to $49,450 (single) and $98,900 (MFJ), up from $48,350 and $96,700 respectively in 2025.
- The 15%/20% boundary also rose. Single filers stay in the 15% bracket up to $545,500 (was $533,400). MFJ couples stay at 15% up to $613,700 (was $600,050).
- Standard deduction increased. Now $15,000 for single filers ($30,000 MFJ), up from $14,600/$29,200 in 2025. This effectively lowers taxable income and can push more gains into the 0% bracket.
- Ordinary income brackets (affecting short-term gains) also adjusted upward by approximately 2.3% across all filing statuses.
- Estate and gift tax exemption rose to $13.99 million per person, preserving the stepped-up basis strategy for large estates.
2. 2026 vs 2025 Long-Term Capital Gains Brackets — Side-by-Side Comparison
The following table compares the long-term capital gains bracket thresholds for 2026 against 2025, for all filing statuses. These are the taxable income levels (after deductions) at which each rate applies:
Single Filers
| Rate | 2025 Threshold | 2026 Threshold | Change |
|---|---|---|---|
| 0% | Up to $48,350 | Up to $49,450 | +$1,100 |
| 15% | $48,351 – $533,400 | $49,451 – $545,500 | +$12,100 wider |
| 20% | Over $533,400 | Over $545,500 | +$12,100 |
Married Filing Jointly
| Rate | 2025 Threshold | 2026 Threshold | Change |
|---|---|---|---|
| 0% | Up to $96,700 | Up to $98,900 | +$2,200 |
| 15% | $96,701 – $600,050 | $98,901 – $613,700 | +$13,650 wider |
| 20% | Over $600,050 | Over $613,700 | +$13,650 |
Head of Household
| Rate | 2025 Threshold | 2026 Threshold | Change |
|---|---|---|---|
| 0% | Up to $64,750 | Up to $66,200 | +$1,450 |
| 15% | $64,751 – $566,700 | $66,201 – $579,600 | +$12,900 wider |
| 20% | Over $566,700 | Over $579,600 | +$12,900 |
Married Filing Separately
| Rate | 2025 Threshold | 2026 Threshold | Change |
|---|---|---|---|
| 0% | Up to $48,350 | Up to $49,450 | +$1,100 |
| 15% | $48,351 – $300,000 | $49,451 – $306,850 | +$6,850 wider |
| 20% | Over $300,000 | Over $306,850 | +$6,850 |
The net effect: a single filer can earn $1,100 more in taxable income (including gains) while staying in the 0% bracket. For a married couple filing jointly, that number is $2,200. While these aren't dramatic shifts, they compound with the higher standard deduction to create meaningful savings — particularly for taxpayers near bracket boundaries.
3. 2026 vs 2025 Short-Term Tax Brackets (Ordinary Income)
Short-term capital gains — profits from assets held one year or less — are taxed at ordinary income rates. These brackets also shifted upward for 2026. Here are the single and MFJ brackets:
Single Filers — Ordinary Income Brackets
| Rate | 2025 Taxable Income | 2026 Taxable Income |
|---|---|---|
| 10% | $0 – $11,925 | $0 – $12,150 |
| 12% | $11,926 – $48,475 | $12,151 – $49,475 |
| 22% | $48,476 – $103,350 | $49,476 – $105,525 |
| 24% | $103,351 – $197,300 | $105,526 – $201,550 |
| 32% | $197,301 – $250,525 | $201,551 – $256,500 |
| 35% | $250,526 – $626,350 | $256,501 – $640,500 |
| 37% | Over $626,350 | Over $640,500 |
Married Filing Jointly — Ordinary Income Brackets
| Rate | 2025 Taxable Income | 2026 Taxable Income |
|---|---|---|
| 10% | $0 – $23,850 | $0 – $24,300 |
| 12% | $23,851 – $96,950 | $24,301 – $98,950 |
| 22% | $96,951 – $206,700 | $98,951 – $211,050 |
| 24% | $206,701 – $394,600 | $211,051 – $403,100 |
| 32% | $394,601 – $501,050 | $403,101 – $513,000 |
| 35% | $501,051 – $751,600 | $513,001 – $768,450 |
| 37% | Over $751,600 | Over $768,450 |
For short-term capital gains, the inflation adjustment means you may pay a lower marginal rate on the same dollar amount of gain compared to 2025. For instance, a single filer with $50,000 in short-term gains on top of $55,000 in wages would have crossed into the 24% bracket in 2025 but remains entirely within the 22% bracket in 2026 — saving $1,000 on that marginal portion.
4. Standard Deduction Increases for 2026
The standard deduction affects your capital gains tax calculation because it reduces your taxable income — the number used to determine which capital gains bracket your gains fall into. Higher standard deduction means lower taxable income, which means more of your gains can potentially fall into the 0% bracket.
| Filing Status | 2025 | 2026 | Increase |
|---|---|---|---|
| Single | $14,600 | $15,000 | +$400 |
| Married Filing Jointly | $29,200 | $30,000 | +$800 |
| Head of Household | $21,900 | $22,500 | +$600 |
| Married Filing Separately | $14,600 | $15,000 | +$400 |
Consider the combined effect: a married couple filing jointly with $129,000 in gross income (wages + gains) has taxable income of $99,000 in 2026 ($129,000 − $30,000 standard deduction). In 2025, the same gross income yielded $99,800 in taxable income ($129,000 − $29,200). The 2026 couple's taxable income falls just $100 above the 0% capital gains ceiling of $98,900 — meaning strategic use of above-the-line deductions (IRA contributions, HSA, etc.) could push their entire gain into the 0% bracket.
5. NIIT Thresholds: Still Not Inflation-Adjusted
Perhaps the most significant non-change for 2026 is the Net Investment Income Tax. The 3.8% NIIT surtax thresholds remain exactly where they were set in 2013:
| Filing Status | NIIT Threshold (Since 2013) |
|---|---|
| Single / Head of Household | $200,000 |
| Married Filing Jointly | $250,000 |
| Married Filing Separately | $125,000 |
When the NIIT was enacted as part of the Affordable Care Act in 2013, the $200,000/$250,000 thresholds were designed to target "high earners." But because Congress did not tie these thresholds to inflation, more middle-income taxpayers cross the line each year. A household earning $250,000 in 2013 would need approximately $330,000 in 2026 to maintain the same purchasing power — yet the NIIT still kicks in at $250,000.
The practical result: in many high-cost-of-living areas, dual-income professional households with modest investment portfolios now trigger the NIIT. A couple earning $200,000 in wages who sells $60,000 in appreciated stock has a MAGI of $260,000 — $10,000 above the threshold. They owe 3.8% on the lesser of their net investment income ($60,000) or the excess over the threshold ($10,000). That's $380 in NIIT on top of their regular capital gains tax.
This bracket creep is particularly impactful for investors with large one-time gains. Selling a rental property, exercising stock options, or receiving a business buyout can push your MAGI well above the threshold for a single year, even if your typical income is below it.
6. What Didn't Change for 2026
While brackets shifted, several important capital gains rules remain exactly the same:
Wash Sale Rule (IRC §1091)
You still cannot claim a capital loss if you repurchase the same or substantially identical security within 30 days before or after the sale. The disallowed loss gets added to the cost basis of the replacement shares. There is no dollar threshold — it applies to any amount. Despite years of discussion about extending this rule to cryptocurrency, no such legislation has been enacted for 2026.
Capital Loss Deduction Limit: $3,000
If your capital losses exceed your capital gains for the year, you can deduct up to $3,000 of the excess against ordinary income ($1,500 for married filing separately). This limit has not been inflation-adjusted since it was set in 1978 — when $3,000 was equivalent to approximately $14,500 in today's dollars. Excess losses carry forward indefinitely.
1031 Like-Kind Exchanges
Real estate investors can still defer capital gains tax by exchanging investment property for "like-kind" property under Section 1031. The 45-day identification period and 180-day closing deadline remain unchanged. This applies only to real property — personal property, stocks, and cryptocurrency do not qualify (a change made permanent by the 2017 Tax Cuts and Jobs Act).
Section 121 Home Sale Exclusion
You can still exclude up to $250,000 (single) or $500,000 (married filing jointly) of capital gain from the sale of your primary residence, provided you owned and lived in the home for at least 2 of the last 5 years. These amounts are not inflation-adjusted and have remained unchanged since 1997. For more on married couples and capital gains, see our dedicated guide.
Qualified Opportunity Zone (QOZ) Program
The QOZ program remains active for 2026 investments, though the original deferral benefit (basis step-up for early investors) has largely expired. New investments in 2026 still qualify for the 10-year exclusion of appreciation within the fund — meaning any gains within the QOZ investment held 10+ years are permanently tax-free.
7. How These Changes Affect Different Taxpayers
The impact of 2026's bracket adjustments depends heavily on your income level and filing status. Here are three common scenarios:
Scenario A: Retiree harvesting gains in the 0% bracket
Profile: Linda, age 67, single, retired. Her only income is $28,000 from Social Security (taxable amount: $18,000) and $6,000 in pension income. She wants to sell appreciated stock to rebalance her portfolio.
- Taxable ordinary income after standard deduction: ($18,000 + $6,000) − $15,000 = $9,000
- 0% bracket ceiling: $49,450
- Room for tax-free gains: $49,450 − $9,000 = $40,450
- In 2025, with the old standard deduction ($14,600) and old 0% ceiling ($48,350): room was ($18,000 + $6,000) − $14,600 = $9,400 ordinary income → $48,350 − $9,400 = $38,950 room
- Benefit: Linda can realize $1,500 more in tax-free gains in 2026 vs 2025 ($40,450 vs $38,950)
For retirees living primarily off investments, the wider 0% bracket creates an opportunity to sell appreciated positions, reset cost basis, and reinvest — locking in tax-free gains and reducing future liability. This is sometimes called "gain harvesting" — the opposite of tax-loss harvesting.
Scenario B: Middle-income investor with a home sale
Profile: The Johnsons, married filing jointly, combined wages of $120,000. They sold their rental property for a $95,000 long-term gain after depreciation recapture.
- Taxable ordinary income: $120,000 − $30,000 standard deduction = $90,000
- This is below the 0% ceiling of $98,900, leaving $8,900 in the 0% bracket
- First $8,900 of gain: 0% → $0
- Remaining $86,100 of gain: 15% → $12,915
- MAGI check: $120,000 + $95,000 = $215,000 — below $250,000 MFJ NIIT threshold. No NIIT.
- In 2025: ordinary income would have been $120,000 − $29,200 = $90,800 → only $5,900 in 0% bracket. Extra tax: ($8,900 − $5,900) × 15% = $450 saved in 2026
Scenario C: High earner with NIIT exposure
Profile: David, single, software engineer with $280,000 in W-2 wages. He exercised stock options resulting in a $150,000 long-term gain.
- Taxable ordinary income: $280,000 − $15,000 = $265,000
- All gains are well above the 0% ceiling ($49,450), so 100% of the gain is in the 15% bracket (combined $415,000 is below the $545,500 threshold for 20%)
- Capital gains tax: $150,000 × 15% = $22,500
- NIIT: MAGI = $280,000 + $150,000 = $430,000. Exceeds $200,000 threshold by $230,000. Net investment income = $150,000. Lesser = $150,000 × 3.8% = $5,700
- Total federal tax on the gain: $28,200 (effective rate: 18.8%)
- Compared to 2025: the higher 15%/20% boundary ($545,500 vs $533,400) doesn't help David since he's within 15% either way. His NIIT is identical. The only benefit is the $400 higher standard deduction reducing his ordinary income tax slightly.
8. Key Dates for 2026 Tax Year
Whether you're making estimated payments on a large capital gain or planning year-end sales, these are the critical deadlines for the 2026 tax year:
| Date | Deadline |
|---|---|
| April 15, 2026 | Q1 estimated tax payment due (for gains realized Jan–Mar 2026) |
| June 16, 2026 | Q2 estimated tax payment due (for gains realized Apr–May 2026) |
| September 15, 2026 | Q3 estimated tax payment due (for gains realized Jun–Aug 2026) |
| January 15, 2027 | Q4 estimated tax payment due (for gains realized Sep–Dec 2026) |
| April 15, 2027 | 2026 tax return filing deadline (Form 1040 + Schedule D) |
| October 15, 2027 | Extended filing deadline (if extension filed by April 15, 2027) |
Estimated payment rule of thumb: If you expect to owe $1,000 or more in tax beyond what's covered by withholding, you should make estimated payments. The safe harbor is to pay at least 100% of your prior year's total tax (110% if your AGI exceeds $150,000) through withholding and estimated payments to avoid underpayment penalties.
For large gains realized late in the year (Q4), you can often avoid penalties by increasing your W-2 withholding rather than making an estimated payment — withholding is treated as paid evenly throughout the year regardless of when it was actually withheld. This is the "December withholding trick" that can eliminate the need for quarterly estimated payments on unexpected gains.
9. Planning Strategies for 2026
The 2026 bracket adjustments create specific opportunities for proactive tax planning. Here are the most impactful strategies to consider this year:
Strategy 1: Maximize the wider 0% bracket
With the 0% threshold now at $49,450 (single) / $98,900 (MFJ), more taxpayers than ever can realize long-term gains completely tax-free. If your taxable income (after deductions) leaves room below these ceilings, consider "gain harvesting" — intentionally selling appreciated positions to fill up the 0% bracket, then immediately reinvesting. You pay zero federal tax and reset your cost basis higher, permanently reducing future gain. This is especially valuable for:
- Early retirees living off savings before Social Security kicks in
- Anyone taking a gap year or sabbatical with reduced income
- Part-time workers or freelancers with variable income
- Couples where one spouse isn't working
Strategy 2: Bracket-boundary awareness
If you're near the boundary between the 0% and 15% bracket (or 15% and 20%), consider splitting a large sale across two tax years. Selling half in December 2026 and half in January 2027 can keep each year's gain within a lower bracket — potentially saving thousands. Use our capital gains calculator to model both scenarios.
For example, a single filer with $40,000 in ordinary taxable income has $9,450 of 0% room. If they have a $50,000 gain, selling $9,450 in 2026 (tax-free) and deferring the rest to 2027 — where the 0% ceiling will likely rise again — can save $1,418 in federal tax (vs. selling all in one year).
Strategy 3: Year-end tax-loss harvesting
Review your portfolio in Q4 for positions trading below your cost basis. Realizing losses offsets gains dollar-for-dollar and can turn a taxable event into a tax-neutral one. Remember:
- Short-term losses first offset short-term gains (taxed at higher ordinary rates)
- Net remaining losses offset long-term gains
- Up to $3,000 of excess losses offset ordinary income
- Unused losses carry forward indefinitely
- Avoid the wash sale rule by waiting 31 days or purchasing a similar (but not identical) fund
Strategy 4: Accelerate deductions to expand the 0% bracket
Every dollar of deduction you can claim reduces your taxable income and potentially moves gains into a lower bracket. For 2026, consider:
- Traditional IRA contributions: Up to $7,000 ($8,000 if 50+) — deductible if you meet income limits
- HSA contributions: $4,300 single / $8,550 family — triple tax benefit
- Charitable donations: Bunch multiple years of giving into 2026 to itemize above the $15,000/$30,000 standard deduction threshold
- State/local tax prepayment: Up to the $10,000 SALT cap
Strategy 5: Manage NIIT exposure
Since the NIIT threshold is permanently stuck at $200,000/$250,000, high earners should plan for it as a given rather than an exception. Strategies include:
- Spreading gains across multiple years to stay below the threshold in each
- Increasing participation in rental activities to qualify as "material participation" (active rental income is exempt from NIIT)
- Contributing to tax-deferred accounts to reduce MAGI
- Harvesting losses to reduce net investment income
Strategy 6: Use state tax planning alongside federal
Don't forget that state capital gains taxes apply in addition to federal rates. If you're in a high-tax state like California (13.3%) or New York (10.9%), the combined rate can approach 37%. Strategies like installment sales, Qualified Opportunity Zone reinvestment, or timing sales around a move to a no-income-tax state (Florida, Texas, Nevada) can have an outsized impact. See our state-by-state comparison for details.
10. Frequently Asked Questions
Did capital gains tax go up in 2026?
No. The federal capital gains tax rates remain unchanged at 0%, 15%, and 20% for long-term gains. The income thresholds for each bracket were adjusted upward for inflation by approximately 2.3%, meaning you can actually earn slightly more before hitting the next rate. Short-term capital gains are still taxed at ordinary income rates, which also saw upward threshold adjustments. No new legislation changed the rate structure for 2026.
What is the 0% capital gains bracket for 2026?
For 2026, you pay 0% federal tax on long-term capital gains if your total taxable income (including the gains) stays below: $49,450 (single), $98,900 (married filing jointly), $66,200 (head of household), or $49,450 (married filing separately). These thresholds are based on IRS Revenue Procedure 2025-32 and represent an increase from the 2025 levels of $48,350 / $96,700 / $64,750 / $48,350.
What is the maximum capital gains tax rate for 2026?
The maximum federal rate on long-term capital gains is 20%, which applies to taxable income above $545,500 (single) or $613,700 (MFJ). However, high earners may also owe the 3.8% Net Investment Income Tax, bringing the effective maximum to 23.8%. Add state taxes and the all-in rate can exceed 37% in states like California. Collectibles are taxed at up to 28%, and unrecaptured Section 1250 depreciation at up to 25%.
How much more can I earn tax-free on capital gains in 2026 vs 2025?
Single filers gain an additional $1,100 in the 0% bracket ($49,450 vs $48,350), plus an extra $400 from the higher standard deduction — a combined $1,500 in expanded tax-free capacity measured from gross income. Married filing jointly couples gain $2,200 in bracket room plus $800 in additional standard deduction, totaling $3,000 more in effective tax-free capacity. This means a married couple could potentially shelter $3,000 more in gains at the 0% rate compared to 2025.
When were the 2026 capital gains brackets announced?
The IRS published Revenue Procedure 2025-32 in the fall of 2025, which contained all inflation-adjusted tax parameters for tax year 2026, including the capital gains bracket thresholds, standard deduction amounts, and ordinary income brackets. This is the official source for all figures cited in this guide. The IRS typically releases the following year's parameters each October or November.
Should I sell investments before or after the 2026 changes took effect?
Since the 2026 adjustments are favorable (wider brackets and higher standard deduction), waiting until 2026 to realize gains was generally advantageous for taxpayers near bracket boundaries. However, the differences are modest (2.3% threshold increases), so timing decisions should be driven primarily by investment merit and your overall tax picture rather than small bracket shifts. If you have gains to realize, use our calculator to model both years and see the actual dollar difference.
