For 2026, the IRS inflation-adjusted capital gains brackets under Rev. Proc. 2025-32 push the long-term 0% threshold to roughly $48,350 for single filers and $96,700 for married couples filing jointly—up about 2.7% from 2025. If you’re planning to sell appreciated stock, investment real estate, or a business interest this year, those numbers determine whether your gain costs you nothing in federal tax or triggers a 15% or 20% rate plus the 3.8% Net Investment Income Tax.
Long-Term vs. Short-Term: The One-Year Rule That Changes Everything in 2026
The IRS taxes capital gains at two entirely different rate schedules depending on how long you held the asset. Hold for one year or less and the gain is short-term—taxed as ordinary income at your marginal bracket, which in 2026 runs from 10% up to 37%. Hold for more than one year and the gain is long-term, eligible for the preferential 0%, 15%, or 20% rates.
For a single filer in the 22% ordinary-income bracket, a $50,000 short-term gain costs roughly $11,000 in federal income tax. The same gain held one day longer—qualifying as long-term—drops to $7,500 at the 15% rate. That $3,500 difference is the entire value of patience.
The 2026 Long-Term Capital Gains Brackets: Exact Thresholds by Filing Status
Capital gains brackets are not the same as ordinary-income brackets. They use taxable income—meaning after the standard deduction—to determine which rate applies. For 2026, the standard deduction is $15,750 for single filers and $31,500 for married couples filing jointly under Rev. Proc. 2025-32.
A married couple with $128,200 in combined wages pays zero in federal tax on long-term gains because their taxable income ($128,200 minus $31,500 = $96,700) sits exactly at the 0%/15% boundary. Add $1 more in taxable income and only the amount above $96,700 gets taxed at 15%—the gain is not all pushed into the higher bracket.
| Filing Status | 0% Rate Up To | 15% Rate Up To | 20% Rate Above |
|---|---|---|---|
| Single | ~$48,350 | ~$533,400 | ~$533,400+ |
| Married Filing Jointly | ~$96,700 | ~$600,050 | ~$600,050+ |
| Head of Household | ~$64,750 | ~$566,700 | ~$566,700+ |
| Married Filing Separately | ~$48,350 | ~$300,025 | ~$300,025+ |
The 3.8% Net Investment Income Tax: When Your Gain Costs 23.8% in 2026
High-income taxpayers face a surcharge on top of the 20% long-term rate. The Net Investment Income Tax (NIIT) under IRC §1411 adds 3.8% to net investment income—including capital gains—once modified adjusted gross income exceeds $200,000 for single filers or $250,000 for married filers. These thresholds are not inflation-adjusted; they have been fixed since 2013.
That means a single filer with $600,000 in MAGI who sells stock with a $200,000 long-term gain pays 20% + 3.8% = 23.8% on the gain. At $47,600 in federal capital gains tax on that one transaction, the NIIT alone accounts for $7,600. See IRS Topic 409 for the full calculation methodology.
Special Rates for Collectibles, Small Business Stock, and Unrecaptured §1250 Gain
Not all long-term gains qualify for 0%/15%/20% treatment. Three categories face higher statutory rates regardless of income:
Collectibles (IRC §1(h)(5)): Gains on art, coins, antiques, gems, stamps, and most precious metals held more than one year are taxed at a maximum 28% rate. This applies to physical gold and silver ETFs structured as grantor trusts—a common surprise for investors who assume ETF gains are always taxed like stock gains.
Unrecaptured §1250 gain: When you sell depreciable real property (rental houses, commercial buildings), the portion of gain attributable to prior depreciation deductions is taxed at a maximum 25% rate. If you bought a rental property for $300,000, claimed $60,000 in depreciation over the years, and sell for $400,000, up to $60,000 of that gain faces the 25% rate—not the standard long-term rate.
Qualified Small Business Stock (§1202): Gains on QSBS held more than five years may be excluded from income entirely—up to $10 million or 10x basis, whichever is greater—if the corporation meets specific requirements. The portion not excluded is taxed at 28%. Confirm eligibility carefully; the IRS has scrutinized §1202 claims aggressively in recent examination cycles.
The $250,000 / $500,000 Home Sale Exclusion Still Applies in 2026
Under IRC §121, single homeowners can exclude up to $250,000 of gain on the sale of a primary residence; married couples filing jointly can exclude up to $500,000. To qualify, you must have owned and used the home as your principal residence for at least two of the five years before the sale. You can use this exclusion once every two years.
The exclusion is not indexed for inflation and has not changed since 1997. In high-cost markets where homes have appreciated $600,000 or more, the amount above the exclusion is a taxable long-term capital gain subject to the standard brackets above—including the NIIT if MAGI exceeds $250,000 for married filers.
Tax-Loss Harvesting in 2026: The $3,000 Deduction Cap and Carryforward Rules
Capital losses offset capital gains dollar-for-dollar. If your losses exceed your gains, you can deduct up to $3,000 of the net loss against ordinary income per year—a limit that has not changed since 1978. Any remaining loss carries forward indefinitely to future tax years.
The wash-sale rule (IRC §1091) disallows a loss if you buy the same or substantially identical security within 30 days before or after the sale. The rule applies across all your accounts, including IRAs—though losses realized inside an IRA are never deductible anyway. Buying a different ETF tracking a different index is generally not a wash sale, but buying the same fund from a different provider often is if the underlying index is identical.
How the 2026 Standard Deduction ($15,750 / $31,500) Affects Your Gains Bracket
Capital gains brackets are applied to taxable income, not gross income. The 2026 standard deduction of $15,750 for single filers and $31,500 for married filers directly reduces the income figure used to place your gains in a bracket.
You are a single filer in 2026 with $38,000 in wages and $25,000 in long-term capital gains from selling appreciated index fund shares. Your taxable income before the gains is $22,250 (wages minus the $15,750 standard deduction). The 0% long-term bracket ends at approximately $48,350 in taxable income. You have $15,000 in unrealized losses in a different fund.
A retired couple with $60,000 in Social Security (50% taxable = $30,000 included in income), $20,000 in pension income, and $30,000 in long-term capital gains has gross income of $80,000. After the $31,500 standard deduction, taxable income is $48,500. The first $48,200 of that ($96,700 threshold minus the $48,500 in ordinary income) sits in the 0% capital gains bracket. Only $300 of the gain faces the 15% rate—a $45 federal tax bill on $30,000 in gains.
Gifting Appreciated Stock in 2026: The $19,000 Annual Exclusion and Basis Rules
Transferring appreciated stock to a family member does not trigger capital gains tax for the donor—but the recipient takes the donor’s original cost basis. If you give your adult child stock worth $50,000 that you purchased for $10,000, you avoid the $40,000 gain, but your child will owe tax on that $40,000 when they eventually sell.
The 2026 annual gift tax exclusion is $19,000 per recipient under Rev. Proc. 2025-32. Gifts above that amount reduce your lifetime estate and gift tax exemption, which stands at $13.99 million in 2026. For donors in the 20% capital gains bracket gifting to a recipient in the 0% bracket, this strategy permanently eliminates the gain from taxation—a meaningful planning tool for families with significant unrealized appreciation.
Estimated Tax Payments: Avoiding the Penalty on 2026 Gains
Capital gains are not subject to withholding. If you sell appreciated assets in 2026 and do not make estimated tax payments, the IRS can assess an underpayment penalty even if you pay the full balance by April 15, 2027. The safe harbor requires either paying 100% of your 2025 tax liability (110% if your 2025 AGI exceeded $150,000) or paying 90% of your actual 2026 liability through quarterly installments.
Quarterly deadlines for 2026 gains: April 15 (Q1), June 16 (Q2), September 15 (Q3), and January 15, 2027 (Q4). Use IRS Direct Pay to make payments without a processing fee. Large one-time gains—from a business sale, real estate transaction, or concentrated stock position—warrant immediate estimated payment in the quarter the gain occurs rather than waiting for year-end.
Stepped-Up Basis at Death: The 2026 Strategy That Eliminates Capital Gains Entirely
Assets transferred at death receive a stepped-up cost basis to the fair market value on the date of death under IRC §1014. An heir who inherits stock worth $200,000 that the decedent bought for $20,000 can sell it immediately and owe zero capital gains tax—the $180,000 of appreciation is permanently forgiven.
Confirm your 2026 filing status and taxable income to determine which capital gains rate applies: 0% (up to ~$47,025 single / ~$94,050 MFJ), 15%, or 20% *
Verify your asset’s holding period exceeds 12 months to qualify for long-term capital gains rates rather than ordinary income rates *
Check whether your income triggers the 3.8% Net Investment Income Tax (NIIT), which applies above $200,000 single / $250,000 MFJ modified AGI *
Identify any unrealized losses in your portfolio that could be harvested to offset gains before the December 31, 2026 tax year deadline
Calculate your adjusted cost basis, including purchase price, commissions, reinvested dividends, and any improvements, to avoid overpaying tax
Consult a CPA or tax advisor about installment sale elections or charitable giving strategies (e.g., donor-advised funds) that could reduce your taxable gain
This makes holding highly appreciated assets until death one of the most powerful capital gains strategies available in 2026. The 2026 estate tax exemption of $13.99 million means the vast majority of estates pass assets with stepped-up basis and owe no estate tax. Absent legislative change, the TCJA provisions that doubled the exemption are scheduled to sunset after December 31, 2025—but Congress extended them; monitor IRS newsroom for any further legislative developments affecting the exemption beyond 2026.
| Strategy | Federal Rate Saved | Key 2026 Limit |
|---|---|---|
| Hold >1 year (long-term) | Up to 20% vs. 37% | 365+ day holding period |
| 0% bracket harvesting | 15% saved per dollar | ~$96,700 taxable income (MFJ) |
| Tax-loss harvesting | Gain offset 1:1 | $3,000 vs. ordinary income |
| Gift to lower-bracket recipient | Up to 20% on transferred gain | $19,000 annual exclusion |
| Stepped-up basis at death | 100% of embedded gain | $13.99M estate exemption |
The IRS announces inflation adjustments for the 2027 tax year in October or November 2026 via a new Revenue Procedure—that release will set the capital gains bracket thresholds, standard deduction, and gift exclusion that govern transactions beginning January 1, 2027.
