Capital Gains Tax: Short-Term, Long-Term, Rates, and IRS Rules for 2026
Capital gains tax is the federal income tax on the profit from selling a capital asset. The IRS states that almost everything a taxpayer owns and uses for personal or investment purposes is a capital asset, and that the gain or loss is the difference between the asset's adjusted basis and the amount realized from the sale. How long the asset was held decides whether the gain is short-term or long-term, and that choice drives which rates apply.
This guide covers the IRS rules most readers search for: the difference between short term and long term capital gains tax, the 2026 federal capital gains tax rate thresholds, how losses are limited, which forms and records are involved, and how California treats capital gains. It addresses federal rules unless a section says otherwise.

What Is Capital Gains Tax?
For readers asking what is capital gains tax, the IRS framework has three parts. First, a capital asset is, in the IRS's words, almost everything owned and used for personal or investment purposes, including a home, household furnishings, and stocks or bonds held as investments. Second, a gain or loss is the difference between the adjusted basis and the amount realized from the sale: a gain if the sale price exceeds the adjusted basis, and a loss if it is less. Third, the IRS states that losses from the sale of personal-use property, such as a home or car, are not tax deductible.
A capital gain tax applies only when an asset is sold or otherwise disposed of, and the amount depends on the gain, the holding period, the taxpayer's taxable income, and the type of asset. Those variables are the reason capital gains taxes cannot be estimated from the sale price alone.
Short Term Capital Gains Tax: The One-Year Holding Period
The IRS draws the line between short-term and long-term at one year. Holding an asset one year or less makes the result short-term, and holding it for more than one year makes it long-term. The IRS explains how to count: the holding period starts the day after the asset was acquired and runs through the day it was disposed of.
Short term capital gains tax is calculated at ordinary income rates. The IRS states that short-term gains are taxed as ordinary income at graduated rates, so the short term capital gains tax rate is the taxpayer's own ordinary rate rather than a separate rate. For the ordinary brackets, see TWC's article on [2026 federal tax brackets](https://www.taxwealthconsultant.com/post/federal-tax-brackets-2026-irvine).
Long Term Capital Gains Tax: How Long-Term Gains Are Taxed?
Long term capital gains tax applies to assets held for more than one year. The IRS describes three regular rates, 0%, 15%, and 20%, and two special maximum rates:
0%, 15%, and 20%: the rate depends on taxable income and filing status. The IRS states that the 20% rate applies to the extent taxable income exceeds the 15% thresholds.
25%: the maximum rate on unrecaptured Section 1250 gain from selling Section 1250 real property.
28%: the maximum rate on net gains from collectibles and on the taxable part of gain from Section 1202 qualified small business stock.
The long term capital gains tax rate therefore turns on taxable income and filing status. Two other IRS holding-period points affect classification. Capital gain distributions from mutual funds are always treated as long-term, regardless of how long the fund shares were held. For certain applicable partnership interests, the Schedule D instructions state that the long-term period is more than three years.
Capital Gains Tax Rate and Capital Gains Tax Brackets for 2026
The long term capital gains tax rate for tax year 2026 depends on taxable income. Revenue Procedure 2025-32 lists the taxable income thresholds below. The 0% rate applies up to the first amount, the 15% rate applies above that up to the second amount, and the 20% rate applies above the second amount.
Filing status | 0% rate up to | 15% rate up to (20% above) |
Married filing jointly and surviving spouses | $98,900 | $613,700 |
Married filing separately | $49,450 | $306,850 |
Head of household | $66,200 | $579,600 |
All other individuals (including single) | $49,450 | $545,500 |
Estates and trusts | $3,300 | $16,250 |
These capital gains tax brackets are separate from the ordinary income brackets that apply to short term capital gains tax rate calculations. The IRS also notes that individuals with significant investment income may owe the net investment income tax, which TWC explains in its article on the Net Investment Income Tax.

How Much Is Capital Gains Tax? The Factors the IRS Uses
Anyone asking how much is capital gains tax is really asking about several inputs, all of which come from the IRS rules above:
The gain itself, which is the amount realized minus adjusted basis
The holding period, which decides whether the gain is short-term or long-term
The taxpayer's taxable income and filing status, which decide the 0%, 15%, or 20% rate on long-term gains
The type of asset, because collectibles, Section 1250 property, and qualified small business stock can have different maximum rates
Any capital losses, which can offset gains
Because these inputs vary, the IRS does not publish a single answer to how much is capital gains tax. It publishes the rules, forms, and thresholds.
Capital Gains Tax Calculator: Inputs Needed for an Accurate Estimate
A capital gains tax calculator works only with the information entered. To use one accurately, gather the sale price and selling costs, the adjusted basis of the asset, the dates acquired and sold, the taxpayer's filing status and expected taxable income, and whether the asset is a collectible, Section 1250 property, or qualified small business stock.
A calculator does not decide whether an item is a capital asset, whether a loss is deductible, or how the holding period is counted. Those are rule questions the IRS answers in Topic 409 and the Schedule D instructions.

Capital Losses and the Limit on Deducting Them
Losses from capital assets held for investment can offset capital gains. The IRS states that when losses exceed gains, the excess can offset other income up to $3,000, or $1,500 if married filing separately. The Schedule D instructions describe this as a deduction for capital losses up to the amount of capital gains plus $3,000 ($1,500 if married filing separately).
Losses above the limit carry forward to later years. The loss is claimed on Form 1040, line 7a, and the Schedule D instructions include a Capital Loss Carryover Worksheet. For TWC's discussion of using carryovers, see the article on capital loss carryovers
Basis Records and Holding-Period Documentation
Reporting capital gains taxes accurately starts with records. The IRS explains in Topic 703 that basis is generally what the taxpayer paid for an asset, including sales tax and purchase-related expenses; for stocks and bonds, basis is the purchase price plus costs such as commissions and transfer fees. Adjusted basis increases with the cost of value-enhancing improvements and decreases with allowable depreciation and insurance reimbursements.
The IRS capital gains guidance adds several record-related rules for investments:
Specific share identification is preferred for cost basis; otherwise first-in, first-out (FIFO) applies. Average basis is allowed only for certain mutual fund and dividend reinvestment shares.
Brokers report basis for covered securities, which are stock acquired after 2010 and mutual fund or dividend reinvestment plan shares acquired after 2011. Noncovered securities require the taxpayer's own records.
For gifted property, basis depends on the donor's adjusted basis and the fair market value at the time of the gift. Property acquired other than by purchase, such as a gift or inheritance, is covered in Publication 551.
Complete basis records also keep the capital gain tax calculation accurate. Holding-period documentation matters because the one-year line changes the tax treatment. Purchase confirmations, brokerage statements, and closing statements are the records that show acquisition and sale dates.
Form 8949 and Schedule D: How Capital Gains Are Reported
The IRS states that most transactions are reported on Form 8949 and then summarized on Schedule D (Form 1040). Short-term items go in Part I of Schedule D and Form 8949, and long-term items go in Part II. The Schedule D instructions explain that Form 8949 is completed before certain Schedule D lines, and that some transactions can be entered as totals on Schedule D lines 1a and 8a instead when specific conditions are met, such as basis being reported to the IRS and no adjustments being needed.
Schedule D also has worksheets for special rates. The 28% Rate Gain Worksheet applies when a taxpayer reported a Section 1202 exclusion on qualified small business stock or had a collectibles gain or loss in Part II of Form 8949. If Schedule D does not apply, the IRS says to check the appropriate box on Form 1040, line 7b.
Capital Gains Tax California: How the State Differs From the IRS?
California rules are separate from federal IRS rules. The California Franchise Tax Board (FTB) states that California does not have a lower rate for capital gains and that all capital gains are taxed as ordinary income. That differs from the federal system, where long-term gains can receive the 0%, 15%, and 20% rates described above.
The FTB also states that if there is a difference between federal and state treatment of a capital gain or loss, the taxpayer should file California Schedule D (540). The capital gains tax California treatment is administered by the FTB, not the IRS, so state-specific questions should be confirmed with the FTB or a California tax professional.
See the FTB page Capital gains and losses. TWC also discusses state-federal differences in its article on California income tax planning.
What the IRS Rules Mean in Practice?
Each practical consideration below follows from a rule stated above.
Track the acquisition date of each asset, because the one-year holding period decides whether the gain is short-term or long-term.
Keep basis records for every purchase, because the gain is figured from adjusted basis.
Review expected taxable income and filing status before selling, because they decide the long-term rate bracket.
Identify unusual asset types, because collectibles, Section 1250 property, and qualified small business stock can have different maximum rates.
Account for capital losses, because they offset gains and are limited against other income.
Separate federal and California treatment, because California taxes capital gains as ordinary income.
