Capital Gains Tax Explained: Short-Term vs Long-Term Rates

Fact-checked by the MyFinancial101 editorial team

Capital gains tax rates split into two categories the moment you sell an asset at a profit, and the difference between them can cost, or save, tens of thousands of dollars depending on when you pull the trigger. The Internal Revenue Service taxes short-term gains at ordinary income rates up to 37%, while long-term gains top out at 20% for most taxpayers, according to IRS Topic 409. Those aren’t abstract percentages; on a $100,000 gain, that spread is a $17,000 real-money difference.

The one-year holding period is the single most consequential deadline in personal investing, yet most investors encounter it only after a costly sale. This guide covers the exact 2025 and 2026 rate brackets for every filing status, a concrete worked example showing what waiting just two extra months actually saves, and several rules, depreciation recapture, the Net Investment Income Tax, collectibles rates, that rarely appear in introductory tax articles.

What Are Capital Gains and Why Do They Matter?

A capital gain is the profit from selling a capital asset, stocks, real estate, cryptocurrency, collectibles, or business interests, for more than you paid. The IRS doesn’t tax paper appreciation; the taxable event is the sale or exchange itself. Until you sell, gains remain unrealized and generate no tax liability.

What Counts as a Capital Asset?

Nearly everything you own and use for investment or personal purposes qualifies: shares of Apple or an S&P 500 index fund, a rental property, Bitcoin, even fine art. The asset’s cost basis, what you originally paid, plus qualifying improvements, is subtracted from your sale proceeds to determine the gain. Get the basis wrong and you’ll either overpay or underpay, both of which create problems with the IRS.

Capital gains matter to long-term wealth building because they directly erode net returns. A 10% annual gain on a stock looks different after taxes depending on when you sell. For investors just starting out, understanding this interaction early pays dividends, literally. Our guide on how to start investing with zero experience covers the basics of asset selection before tax considerations become relevant.

Short-Term vs. Long-Term: The One-Year Rule That Changes Everything

The holding period threshold is exactly one year, and the count is stricter than most people expect. To qualify for long-term treatment, you must hold the asset for more than one year, meaning day 366 or later, not day 365. Selling at exactly 12 months lands you in short-term territory.

How the Clock Works (and What Resets It)

The holding period starts the day after acquisition and ends on the sale date. Certain events reset the clock entirely: a wash-sale disallowance, receiving shares through employee stock options (where the grant date versus exercise date rules vary), or reinvesting a mutual fund distribution in new shares. For investors using mutual funds or ETFs, the fund itself distributes capital gains annually, and the character (short- or long-term) of those distributions is determined at the fund level, not by how long you personally held the shares.

The Real Dollar Cost of Selling Too Early

Consider a concrete example. A single filer with $150,000 in taxable income sells a stock position generating a $50,000 gain. If sold at 11 months, that gain is short-term and taxed at 24% (the applicable ordinary income bracket), producing a $12,000 tax bill. Held two more months past the one-year mark, the same gain becomes long-term and taxed at 15%, producing a $7,500 bill. Waiting roughly 60 days saves $4,500 on a single transaction, with zero change to the underlying investment. The arithmetic is exact: $50,000 × 0.24 = $12,000; $50,000 × 0.15 = $7,500; difference = $4,500.

Short-Term Capital Gains Tax Rates: Taxed as Ordinary Income

Short-term gains carry no preferential rate. They stack on top of your other income and are taxed at whatever marginal bracket that combined total reaches. For 2025, the top rate is 37%, applicable to single filers with taxable income above $626,350, according to Tax Foundation’s 2025 bracket data.

State income taxes compound the hit. California residents face a top state rate of 13.3%, meaning a high-earning single filer in California could see a combined marginal rate of roughly 50% on short-term gains. New York’s top rate adds another 10.9% in state taxes. By contrast, residents of Texas, Florida, or Nevada pay zero state income tax on any gains, short- or long-term. This federal-plus-state gap is a major reason tax-efficient asset location, keeping high-turnover strategies inside tax-advantaged accounts, matters so much in high-tax states.

2025 and 2026 Long-Term Capital Gains Tax Rates: 0%, 15%, or 20%

Long-term capital gains tax rates operate on their own bracket structure, separate from ordinary income brackets, a distinction the Tax Cuts and Jobs Act (TCJA) formalized and which survived the 2025 ordinary bracket sunset intact. Three rates apply: 0%, 15%, and 20%, based entirely on taxable income and filing status.

2025 Long-Term Rate Thresholds by Filing Status

The 3.8% Net Investment Income Tax

High earners face a surcharge beyond the base rate. The Net Investment Income Tax (NIIT), established under the Affordable Care Act, adds 3.8% to investment income, including both short- and long-term capital gains, once MAGI exceeds $200,000 for single filers or $250,000 for married couples filing jointly. At the top, that means an effective federal long-term rate of 23.8% (20% + 3.8%) and a short-term rate of 40.8% (37% + 3.8%). The NIIT is calculated on Form 8960 and filed with your federal return.

Special Capital Gains Rules Most Investors Overlook

Three situations fall outside the standard 0/15/20% structure and catch investors off guard: collectibles, qualified small business stock, and real estate depreciation recapture.

Collectibles, art, antiques, coins, stamps, and precious metals held directly, face a maximum long-term rate of 28%, regardless of your ordinary income bracket. The same 28% cap applies to gains from Section 1202 Qualified Small Business Stock (QSBS) that doesn’t meet full exclusion requirements. Depreciation recapture on real estate (the portion attributable to deductions you took under Section 1250) is taxed at a maximum of 25%, not the standard long-term rate, which surprises many rental property owners at sale. If you’re holding rental property and planning a sale, these recapture rules deserve a separate conversation with a CPA, a tax preparer who only sees you at filing time may not flag them proactively.

How to Reduce What You Owe: Practical Approaches

Tax-Loss Harvesting and the Wash-Sale Rule

Tax-loss harvesting means selling positions at a loss to offset realized gains elsewhere, reducing your net taxable gain for the year. Losses first offset gains of the same type (short-term against short-term, long-term against long-term); excess losses then cross over. Up to $3,000 in net capital losses can offset ordinary income annually, with any remaining balance carried forward indefinitely.

The catch: the wash-sale rule (IRS Section 1091) disallows the loss if you repurchase a “substantially identical” security within 30 days before or after the sale. The rule applies to individual stocks and mutual funds. It does not technically apply to cryptocurrency as of mid-2026, though proposed legislation to close that gap has circulated. For ETFs, the rule is less clear, selling one S&P 500 ETF and buying a different provider’s S&P 500 ETF is a common workaround, but swapping nearly-identical products can draw IRS scrutiny. Using the specific identification method (rather than FIFO) when selling lets you choose exactly which lot to sell, maximizing loss harvesting precision.

Asset Location and Step-Up in Basis

Holding high-growth, high-turnover assets inside a Roth IRA or 401(k) shields every gain from capital gains tax entirely. A stock doubling in value inside a Roth generates zero tax on withdrawal; the same stock in a taxable brokerage account generates a gain taxed at 15% or 20% at sale. That asymmetry compounds significantly over decades, another reason saving for retirement early is worth prioritizing, as we discuss in our post on why retirement savings should come before college funding.

One planning lever most articles skip: the step-up in basis at death. When a beneficiary inherits an appreciated asset, the cost basis resets to the asset’s fair market value on the date of death. A stock bought at $10 and worth $500 at the owner’s death has a new basis of $500 for the heir, meaning a sale the next day generates zero capital gain. For investors holding highly appreciated positions in taxable accounts, gifting strategies during life versus holding until death carry very different tax outcomes for heirs, and the step-up rule is often the deciding factor. Managing taxes is just one piece of keeping more of what you earn; if high-interest debt is also eroding your returns, understanding how to prioritize and negotiate credit card debt can free up more capital to invest in the first place.

Per IRS Topic 409, short-term capital gains are taxed as ordinary income, while long-term capital gains on assets held more than one year qualify for preferential rates of 0%, 15%, or 20% depending on taxable income and filing status.

Frequently Asked Questions

What is the difference between short-term and long-term capital gains tax rates?

Short-term gains (assets held one year or less) are taxed at ordinary income rates ranging from 10% to 37%. Long-term gains (held more than one year) are taxed at 0%, 15%, or 20% depending on your taxable income. The maximum spread between the two is 17 percentage points at the federal level before state taxes are added.

What are the 2025 long-term capital gains tax brackets for single filers?

Single filers with taxable income up to $48,350 pay 0%; from $48,351 to $533,400 they pay 15%; and above $533,400 they pay 20%, per IRS Topic 409. These thresholds apply to tax year 2025 and are subject to inflation adjustment for 2026.

Do I owe capital gains tax if I reinvest the proceeds immediately?

Yes. Reinvesting proceeds does not defer or eliminate the tax owed on a realized gain. The taxable event is the sale itself, regardless of what you do with the money afterward. The only exceptions are specific vehicles like Qualified Opportunity Zone funds, which offer structured deferral under IRS rules.

Does the 3.8% Net Investment Income Tax apply to everyone?

No, the NIIT applies only to taxpayers whose MAGI exceeds $200,000 (single) or $250,000 (married filing jointly). Below those thresholds, the standard 0%, 15%, or 20% long-term rates are the full federal burden. Above them, the surcharge applies to the lesser of net investment income or the excess MAGI over the threshold.

How are capital gains from cryptocurrency taxed?

The IRS treats cryptocurrency as property, so the same short-term and long-term rules apply. Every sale, exchange, or conversion of one cryptocurrency to another is a taxable event. Gains on crypto held more than one year qualify for the long-term rates; gains on crypto held one year or less are taxed as ordinary income.

Can capital losses offset ordinary income?

Partially. Net capital losses can offset up to $3,000 of ordinary income per year ($1,500 if married filing separately). Any remaining loss carries forward to future tax years indefinitely and retains its character (short-term or long-term) until fully used.

Are collectibles taxed at the same long-term capital gains rate as stocks?

No. Long-term gains on collectibles, art, coins, stamps, and precious metals held directly, face a maximum federal rate of 28%, not the standard 20% maximum that applies to stocks and most other assets. This higher cap applies regardless of your ordinary income bracket.
