What Is Capital Gains Tax and What Are the Current Rates?

‍Capital gains tax is the federal tax you owe on the profit from selling an asset for more than you paid for it. Long-term capital gains, meaning gains on assets held more than one year, are taxed at 0%, 15%, or 20% depending on your taxable income and filing status. Short-term capital gains, on assets held one year or less, are taxed as ordinary income at rates from 10% to 37%.

The sections below cover which assets trigger the tax, the current 2025 and 2026 rate brackets, how the calculation works on real dollar amounts, the state layer that sits on top of the federal bill, the exclusions that remove some gains from taxation entirely, and the forms and deadlines that govern reporting.

Key Takeaways

• Long-term capital gains are taxed at 0%, 15%, or 20%. Short-term capital gains are taxed at ordinary income rates of 10% to 37%.
• The dividing line is one year. Hold an asset more than one year and the long-term rates apply. Sell at or before the one-year mark and ordinary rates apply.
• In 2026, the 0% rate covers taxable income up to $49,450 for single filers and $98,900 for married couples filing jointly.
• A separate 3.8% net investment income tax applies once modified adjusted gross income passes $200,000 for single filers or $250,000 for joint filers.
• Nine states levy no state capital gains tax at all, while California's top rate reaches 13.3%. The state layer often moves the total bill more than any federal decision.
• The tax applies only to realized gains. Holding an appreciated asset produces no tax until you sell.

What Is Capital Gains Tax?

Capital gains tax is a federal tax on the profit you realize when you sell a capital asset for more than its adjusted basis. A capital asset covers most property a person owns, including stocks, bonds, mutual funds, exchange-traded funds, cryptocurrency, real estate, business interests, and tangible items such as artwork, vehicles, and collectibles.

Adjusted basis is the number the entire calculation depends on. Basis begins as the purchase price, then increases with commissions, transaction fees, and qualifying improvements, and decreases with depreciation claimed over the holding period. Depreciation claimed on rental property carries its own consequence at sale, which the real estate section below addresses directly.

The gain itself is arithmetic. Sale proceeds minus adjusted basis equals the capital gain. Sale proceeds below adjusted basis produce a capital loss instead, and capital losses carry real value because they offset gains dollar for dollar.

Capital losses that exceed capital gains reduce ordinary income by up to $3,000 per year, or $1,500 for married taxpayers filing separately, according to the IRS. Losses beyond that annual limit carry forward indefinitely to offset gains in future years. This carryforward mechanism means a bad year in the market retains planning value long after the year closes.

What Assets Trigger Capital Gains Tax?

Capital gains tax is triggered by the sale, exchange, or other disposition of a capital asset at a price above its adjusted basis. The trigger is the transaction, not the appreciation. An asset can double in value across a decade and generate no tax liability at all until the year you dispose of it.

Disposition covers more transaction types than most sellers expect. Selling stock triggers it. Trading one cryptocurrency for another triggers it, because the IRS treats digital assets as property rather than currency. Selling a rental property triggers it. Receiving a capital gain distribution from a mutual fund triggers it even when you sold nothing yourself, because the fund realized gains internally and passed them through to shareholders.

What Is the Difference Between Realized and Unrealized Capital Gains?

A realized capital gain is profit locked in by an actual sale, while an unrealized capital gain is paper appreciation on an asset you still hold. Only realized gains are taxable. Paper appreciation on an asset you still hold produces no federal tax liability, no matter how large the appreciation grows.

Paper appreciation does carry one indirect exposure. Investors who hold mutual funds or exchange-traded funds inherit a proportional share of the fund's internal unrealized gains, and those gains become taxable to shareholders when the fund manager sells the underlying positions and distributes the proceeds. Distributions of that kind arrive on Form 1099-DIV and are taxable in the year received.

What Assets Are Not Subject to Capital Gains Tax?

Assets held inside tax-advantaged accounts are not subject to capital gains tax while they remain in the account. Positions bought and sold within a 401(k), traditional IRA, Roth IRA, 529 plan, or health savings account generate no capital gains tax at the transaction level. Traditional accounts convert the eventual withdrawal into ordinary income, while qualified Roth and 529 withdrawals escape tax entirely under the account rules.

Tax-exempt municipal bond interest also sits outside the capital gains system, though a municipal bond sold at a premium can still produce a taxable capital gain on the sale itself. Interest and gain are separate items, and only the interest carries the exemption.

What Is the Difference Between Short-Term and Long-Term Capital Gains?

Short-term capital gains come from assets held one year or less, and long-term capital gains come from assets held more than one year. That single boundary splits the entire rate system in two, and it is measured to the day. An asset bought on March 10 and sold on March 10 of the following year is still short term, because the holding period requires more than one year rather than exactly one year.

The rate consequence of that boundary is substantial. Short-term gains enter your return as ordinary income and are taxed at the same 10% to 37% brackets that apply to wages, according to the IRS. Long-term gains receive a separate preferential schedule topping out at 20%, and the IRS reports that most taxpayers pay no more than 15% on long-term gains.

Holding an appreciated position across the one-year line is the most direct lever available to a seller with discretion over timing. Sellers who lack that discretion, such as founders bound by an acquisition close date or homeowners moving for work, need the surrounding decisions to carry the weight instead. Deliberate tax planning handles the sequence and structure of those transactions before the sale date arrives rather than after.

What Are the Current Capital Gains Tax Rates?

The current long-term capital gains tax rates are 0%, 15%, and 20%, applied by taxable income and filing status. The bracket thresholds are indexed for inflation each year, so the 2026 figures sit modestly above the 2025 figures at every tier. Short-term rates track the ordinary income brackets and are not shown separately below.

Sources: IRS Revenue Procedure 2025-32 (2026 inflation adjustments); IRS Topic No. 409, Capital Gains and Losses. Short-term capital gains are taxed as ordinary income under the federal income tax brackets.

Two rate exceptions sit outside this grid. Long-term gains on collectibles, including coins, precious metals, antiques, and fine art, are capped at 28% rather than 20%, according to the IRS. Gain attributable to depreciation previously claimed on real property carries a maximum rate of 25% under the unrecaptured Section 1250 rules.

A third layer applies above certain income levels. The net investment income tax (NIIT) adds 3.8% to investment income, including capital gains, once modified adjusted gross income passes $200,000 for single and head of household filers, $250,000 for joint filers, or $125,000 for married taxpayers filing separately. Those thresholds were written into law in 2013 and have never been indexed for inflation, which the Tax Policy Center notes pulls more taxpayers into the surtax every year. The Bipartisan Policy Center reports that 8.1 million returns paid more than $39 billion in net investment income tax in 2023, more than double the number of returns that paid it in the first year of the tax.

Who Qualifies for 0% Capital Gains?

You qualify for the 0% capital gains rate when your total taxable income, including the gain itself, falls below $49,450 as a single filer or $98,900 as a joint filer in 2026. Taxable income here means income after deductions, which matters because the standard deduction pushes the practical gross income ceiling meaningfully higher than the bracket figure suggests.

Retirees in the gap years between leaving work and starting Social Security frequently land inside this bracket without realizing it. So do business owners in a low-revenue year and households where one earner has stepped back temporarily. Realizing gains deliberately during a low-income year converts appreciation into permanently untaxed profit and resets basis higher for the future.

How Is Capital Gains Tax Calculated?

Capital gains tax is calculated by subtracting adjusted basis from sale proceeds, classifying the result by holding period, netting gains against losses, and applying the rate that matches your taxable income and filing status. The sequence below reflects the order the calculation actually runs on a return.

1. Determine net proceeds. Start with the gross sale price and subtract selling costs such as broker commissions, transfer fees, and closing costs.
2. Establish adjusted basis. Take the original purchase price, add acquisition costs and qualifying capital improvements, then subtract any depreciation claimed.
3. Compute the raw gain or loss. Subtract adjusted basis from net proceeds.
4. Classify by holding period. Count from the day after acquisition through the sale date. More than one year is long term, one year or less is short term.
5. Net gains against losses. Offset long-term gains with long-term losses and short-term gains with short-term losses first, then net the two categories against each other.
6. Apply the correct rate. Stack the net long-term gain on top of your other taxable income, apply the 0%, 15%, or 20% tier it lands in, and add the 3.8% net investment income tax if your modified adjusted gross income exceeds the threshold.

What Is Cost Basis and How Does It Affect Capital Gains Tax?

Cost basis is the amount you have invested in an asset for tax purposes, and it directly reduces the taxable gain on sale. Every dollar of legitimate basis you can document removes a dollar from the taxable gain, which makes recordkeeping one of the highest-return habits an investor or property owner can maintain.

Basis grows through more channels than the purchase receipt shows. Reinvested dividends add to basis in a brokerage position. A new roof, an addition, or a kitchen renovation adds to basis in a property. Legal fees connected to acquiring the asset add to basis. Sellers who never tracked these additions routinely overstate their gain and overpay, because the missing basis is invisible on the broker statement and equally invisible to the IRS.

How Much Capital Gains Tax Do I Pay on $100,000 Profit?

You pay $15,000 in federal capital gains tax on a $100,000 long-term profit taxed entirely at the 15% rate. The 15% tier is where the large majority of long-term gains land, since it spans taxable income from roughly $49,451 to $545,500 for a single filer in 2026.

The same $100,000 profit produces a very different result at the extremes. A taxpayer whose total taxable income stays under the 0% ceiling pays nothing on the gain. A taxpayer holding the same position for eleven months instead of thirteen pays ordinary rates, which reach 37%, turning a $15,000 bill into as much as $37,000 on identical economics.

How Much Capital Gains Tax Will I Pay on a Gain of $200,000?

A $200,000 long-term capital gain taxed at 15% produces $30,000 in federal capital gains tax. Gains at this level frequently push modified adjusted gross income past the net investment income tax threshold, which adds 3.8% on the portion of investment income above $200,000 for single filers or $250,000 for joint filers.

How Much Capital Gains Do I Pay on $300,000?

A $300,000 long-term capital gain taxed at 15% produces $45,000 in federal capital gains tax, before the net investment income tax. The surtax at this level is rarely avoidable for a taxpayer with ordinary wage income, so the realistic combined federal rate on much of the gain is 18.8% rather than 15%.

Splitting a single large disposition across two tax years is one of the few structural responses available at this size. An installment sale, where the buyer pays across multiple years and the seller recognizes gain proportionally as payments arrive, spreads the gain across more than one bracket year and can keep part of it below the surtax threshold.

How Much Capital Gains Tax Will I Pay on $500,000?

A $500,000 long-term capital gain taxed at 15% produces $75,000 in federal capital gains tax, plus roughly $19,000 in net investment income tax for a filer whose investment income sits fully above the surtax threshold. Sellers whose total taxable income crosses $545,500 as a single filer or $613,700 as a joint filer in 2026 move the top slice of the gain into the 20% tier, and the combined federal rate on that slice reaches 23.8%.

Concentration is the real risk at this level. A single business sale, a real estate disposition, or an equity liquidation can lift a household from a 15% year into a 23.8% year on one transaction, and the increase applies only to the portion of the gain sitting above the threshold rather than to the whole amount.

Do Capital Gains Push You Into a Higher Tax Bracket?

Capital gains do not push your ordinary income into a higher bracket, but they stack on top of ordinary income and can push the gain itself into a higher capital gains tier. The two rate schedules run in parallel rather than merging. Wages fill the ordinary brackets first, then the long-term gain sits above that income and is taxed under the 0%, 15%, and 20% schedule.

Stacking produces a result many sellers find counterintuitive. A married couple with $90,000 in wages has room under the $98,900 zero-rate ceiling, so a small long-term gain is taxed at 0% while a larger gain crosses into 15% partway through. The gain is split across tiers, exactly as ordinary income is split across ordinary brackets.

Stacking also reaches beyond the capital gains schedule itself. A large realized gain raises modified adjusted gross income, which can reduce eligibility for income-based credits, increase the taxable portion of Social Security benefits, and raise Medicare premium surcharges two years later. Those secondary effects often cost more than the rate difference that prompted the sale.

Are Capital Gains Adjusted for Inflation?

Capital gains are not adjusted for inflation. The Tax Policy Center confirms that gains and losses are calculated in nominal dollars, so a property bought thirty years ago is taxed on the full nominal spread between purchase price and sale price even when a meaningful share of that spread reflects currency erosion rather than real appreciation.

Nominal treatment hits long-held assets hardest. Sellers of family land, founder shares, and legacy real estate carry the largest gap between nominal gain and real gain, which makes basis documentation and exclusion planning disproportionately valuable for those holdings.

Is Capital Gains Tax Federal or State?

Capital gains tax is both federal and state, and the two layers are calculated separately. The federal layer applies to every US taxpayer under the 0%, 15%, and 20% schedule. The state layer depends entirely on residency at the time of sale, and it ranges from nothing at all to more than 13%.

Most states that tax capital gains simply fold them into ordinary income and apply the standard state rate, giving no preference for long holding periods. A smaller group applies reduced rates, partial exclusions, or deductions. Washington runs a separate structure entirely, imposing a 7% excise tax on long-term gains above an annual inflation-adjusted threshold and 9.9% on gains above $1 million, despite having no general income tax.

Which States Have No Capital Gains Tax?

Nine states levy no state capital gains tax, including Florida, Texas, Nevada, Tennessee, Wyoming, South Dakota, Alaska, and New Hampshire, with Missouri now allowing a full deduction for qualifying gains. Kiplinger reports that California sits at the opposite end with a top rate of 13.3%, followed by New York and New Jersey above 10%.

The spread produces real dollars on a single transaction. A $1 million long-term gain realized by a California resident carries roughly $133,000 in state tax that the same gain realized by a Miami resident does not carry at all. We work with sellers across every state, and residency at the moment of sale is frequently the single largest variable in the total bill, larger than any federal election available on the return.

How Do You Avoid Paying Taxes on Capital Gains?

You avoid paying taxes on capital gains by holding assets inside tax-advantaged accounts, holding taxable positions more than one year, offsetting gains with realized losses, claiming available exclusions, and donating appreciated assets rather than cash. Each method is a specific provision of the tax code rather than an aggressive position, and each has conditions that have to be met precisely.

• Tax-advantaged accounts. Gains realized inside a 401(k), IRA, Roth IRA, 529, or health savings account generate no capital gains tax at the transaction level.
• Extended holding periods. Crossing the one-year line moves a gain from ordinary rates as high as 37% down to a maximum of 20%.
• Tax-loss harvesting. Selling depreciated positions to realize losses offsets realized gains directly, with the wash sale rule prohibiting repurchase of a substantially identical security within 30 days before or after the sale.
• Charitable transfers of appreciated assets. Donating an appreciated security to a qualified charity removes the embedded gain from your return while supporting the charitable deduction.
• Statutory exclusions. The primary residence exclusion, qualified small business stock, and Opportunity Fund investments each remove specific categories of gain from taxation under defined conditions.
• Basis step-up at death. Inherited assets receive a basis reset to fair market value on the date of death, which eliminates the appreciation accumulated during the original owner's lifetime.

How Can You Lower Your Capital Gains Tax?

You lower your capital gains tax primarily by controlling the year the gain lands in and by maximizing documented basis before the sale closes. Timing and basis are the two variables a seller can still influence, and both close off permanently once the transaction settles.

Timing decisions include deferring a sale into a lower-income year, accelerating a sale into a year with harvested losses available, and structuring an installment sale to spread recognition. Basis decisions include locating improvement receipts, reinvested dividend records, and acquisition cost documentation before the closing statement is drafted. Both categories reward decisions made months ahead of the transaction, which is why we treat proactive tax planning as a year-round exercise rather than a filing-season one.

How Does Capital Gains Tax Work on Real Estate?

The rules covered so far apply to every asset class equally. Real estate, small business stock, and digital assets each carry additional provisions on top of those rules, and the three sections that follow address them in turn.

Capital gains tax on real estate works the same way as on securities, with the significant addition of a primary residence exclusion and a separate rate on recaptured depreciation. Homeowners may exclude up to $250,000 of gain as single filers and up to $500,000 as joint filers, according to the IRS, provided they owned and used the property as a principal residence for at least two of the five years preceding the sale and have not claimed the exclusion on another home in the prior two years.

Investment property receives no such exclusion. The entire gain on a rental or commercial property is taxable, split between the appreciation portion taxed at long-term rates and the depreciation portion taxed under the recapture rules described below.

Can You Reinvest Your Capital Gains to Avoid Taxes?

You can reinvest capital gains to defer taxes on investment real estate through a Section 1031 like-kind exchange, but reinvesting proceeds from a stock sale does not avoid or defer the tax. The distinction trips up a large number of sellers who assume that buying a replacement asset resets the clock.

A 1031 exchange applies only to real property held for business or investment purposes, and it carries strict mechanics. The replacement property must be identified within 45 days of the sale and acquired within 180 days, and the proceeds must pass through a qualified intermediary rather than the seller's own account. Missing either deadline converts the entire deferred gain into a currently taxable one.

Opportunity Funds offer a second reinvestment route with a different structure. Gains reinvested into a qualified Opportunity Fund are deferred, and appreciation on the fund investment itself is excluded from tax entirely once the investment has been held for at least ten years, according to the Tax Policy Center.

What Is Depreciation Recapture on a Rental Property Sale?

Depreciation recapture is the portion of a rental property gain attributable to depreciation deductions previously claimed, taxed at a maximum rate of 25% rather than the standard long-term rates. This is unrecaptured Section 1250 gain, and it applies whether or not the owner actually claimed the depreciation, because the code requires recapture on depreciation allowed or allowable.

The consequence for long-term landlords is significant. A property held for two decades has generated substantial depreciation deductions, each of which lowered adjusted basis and therefore enlarged the eventual gain. Sellers who model their tax exposure using only the 15% or 20% long-term rate consistently underestimate the bill, sometimes by tens of thousands of dollars, because the recapture slice was never in the model.

What Is the Lifetime Capital Gains Exemption?

The United States has no general lifetime capital gains exemption, though several targeted exclusions remove specific categories of gain from federal taxation. The term itself comes from Canadian tax law, where a lifetime exemption does exist, and it circulates in US searches as a result. American taxpayers rely instead on the primary residence exclusion, qualified small business stock, Opportunity Fund treatment, and the basis step-up at death.

What Makes You Exempt From Capital Gains?

You are exempt from capital gains tax when the gain falls within a statutory exclusion or when your total taxable income keeps the gain inside the 0% bracket. Age, retirement status, and reinvestment intent create no exemption on their own, despite persistent belief to the contrary.

The exclusions that do exist are specific and conditional. Each requires meeting defined ownership periods, entity requirements, or income thresholds, and each has to be claimed correctly on the return rather than assumed.

What Is Qualified Small Business Stock?

Qualified small business stock (QSBS) is stock in an eligible domestic C corporation that allows non-corporate shareholders to exclude a substantial portion of the gain on sale under Section 1202. The One Big Beautiful Bill Act, signed July 4, 2025, rebuilt this provision, and the new terms are far more generous than the version most published guidance still describes.

For stock acquired after July 4, 2025, the exclusion now runs on a tiered holding period: 50% of gain excluded at three years, 75% at four years, and 100% at five years. The per-issuer exclusion cap rose from $10 million to $15 million, and the issuing corporation's aggregate gross asset ceiling rose from $50 million to $75 million, expanding the universe of companies whose stock can qualify. Gain taken into account but not excluded under the three-year and four-year tiers is taxed at 28% rather than 20%.

Entity structure determines eligibility from day one, since only C corporation stock qualifies and the stock must be acquired at original issuance. Companies operating as LLCs or S corporations cannot issue QSBS in that form, which makes the business formation decision a capital gains decision years before any exit occurs.

Florida residency compounds the benefit for anyone in this position. A founder living in a state with no capital gains tax faces no state-level layer on the non-excluded portion, which is why we see so many startup founders establish residency well ahead of a liquidity event rather than during it.

How Does Capital Gains Tax Work on Cryptocurrency?

Capital gains tax on cryptocurrency works exactly as it does on stock, because the IRS treats digital assets as property rather than currency. Selling crypto for dollars is a taxable event, trading one token for another is a taxable event, and using crypto to purchase goods or services is a taxable event measured by the fair market value at the moment of the transaction.

Reporting for digital assets changed materially over the past two years. Brokers were required to report gross proceeds on Form 1099-DA for transactions effected on or after January 1, 2025, and basis reporting became mandatory for covered digital assets acquired on or after January 1, 2026, according to the IRS. Assets acquired before that date or transferred in from self-custody remain non-covered, meaning the taxpayer carries full responsibility for calculating basis.

The gap between what the broker reports and what the taxpayer can substantiate is where most digital asset problems begin. Reconstructing basis across multiple exchanges, wallets, and years of activity is the bulk of the work in crypto tax engagements, and it is far easier done contemporaneously than retroactively.

What Happens If I Don't Report Capital Gains?

If you don't report capital gains, the IRS matches the proceeds figure your broker already filed against your return and issues a notice proposing additional tax, penalties, and interest. Brokers file Form 1099-B for securities, Form 1099-DIV for fund distributions, and Form 1099-DA for digital assets, so the agency generally holds the sale information before the return is even due.

The automated matching program produces a specific notice in these cases. A CP2000 notice proposes an adjustment based on the third-party information the IRS received, and because the agency knows proceeds but frequently does not know basis, the proposed tax is often calculated as though the entire sale price were profit.

That distinction matters enormously. A taxpayer who sold $80,000 of stock with a $75,000 basis owes tax on $5,000 of gain, while an unanswered notice can assess tax on the full $80,000. Responding with documented basis typically reduces or eliminates the proposed amount, and the deadline to respond is printed on the notice itself. The wider family of IRS notices follows similar timelines, and each one carries consequences for letting the response window close.

Deliberate omission sits in a different category from oversight. Accuracy-related penalties apply to substantial understatements, and the statute of limitations extends from three years to six when more than 25% of gross income is omitted. We provide IRS representation for taxpayers already holding a notice, and the outcomes are consistently better when the response is prepared before the deadline rather than after a second letter arrives.

When Do You Pay Capital Gains Tax?

You pay capital gains tax for the year in which you sold the asset, reported on the return filed the following April. A sale completed in 2026 is reported on the 2026 return filed by April 2027. Holding an appreciated asset across a year boundary creates no liability, because the tax attaches to the realization event rather than to the calendar.

April is not always the operative deadline, however. The federal system runs on pay-as-you-go, and a large gain realized in the first half of the year can create an obligation well before the filing date.

Do You Have to Pay Estimated Taxes on Capital Gains?

You have to pay estimated taxes on capital gains when withholding from other income sources will not cover the additional liability the gain creates. Quarterly estimated payments are due in April, June, September, and the following January, and underpayment penalties accrue on any quarter that falls short even when the return is eventually paid in full.

Safe harbor rules provide the practical protection here. Paying at least 100% of the prior year's total tax, or 110% for higher-income taxpayers, generally shields against underpayment penalties regardless of how large the current-year gain turns out to be. Taxpayers who miss the safe harbor and cannot cover the balance at filing can request an installment agreement, though interest continues to accrue on the unpaid amount.

What Forms Do You Use to Report Capital Gains?

You report capital gains on Form 8949 and Schedule D of your Form 1040. Form 8949 lists each individual transaction with acquisition date, sale date, proceeds, and basis. Schedule D aggregates those transactions, nets short-term against long-term, and carries the final figure to the return.

The supporting documents arrive from third parties. Form 1099-B covers securities sales, Form 1099-DIV covers capital gain distributions from funds, and Form 1099-DA covers digital asset proceeds. Taxpayers with years of missing returns face a compounded version of this problem, since each open year carries its own unreported transactions, and the path forward on unfiled returns starts with reconstructing basis across every affected year.

Timing and documentation together determine most of what a seller actually pays. Coordinating the sale year, the basis file, the estimated payment schedule, and the state residency question ahead of a transaction is the substance of the tax strategy work we do with clients holding appreciated assets.
