Introduction
Holding an investment for than a year before selling it can mean you pay a lower federal tax rate compared to what you would pay on regular income. But “lower” does not mean the same rate, for all people. The long-term capital gains tax you pay depends on your income, your filing status and how much of your profit falls into each tax bracket. This guide explains the federal long-term capital gains rates shows how the calculation is done and demonstrates how to use the MultiCalculators.com calculator to get an estimate of your own tax.
Quick Answer
Long-term capital gains are profits you make when you sell something you owned for than one year. For the 2026 tax year the government taxes these gains at 0%, 15% or 20%, at the level. The rate you pay depends on how money you make and how you file your taxes. People who earn a lot might also have to pay a 3.8% tax called the Net Investment Income Tax on top of these rates.
What Is Long-Term Capital Gains Tax?
The federal tax on profit from selling something like stock or a mutual fund is called long-term capital gains tax. This tax is for things you owned for than one year. When you sell something you owned for a time like investment real estate you get a better tax deal on the profit. This is different from selling something you owned for a time because the tax on short-term gains is the same as the tax on the money you earn from your job.
How Long-Term Capital Gains Tax Works
The long-term capital gains have a tax schedule. It has three parts: 0%, 15% and 20%. Long-term capital gains are added to your income to see which tax bracket they are in. This is called “stacking” of long-term capital gains. So a long-term capital gain of $20,000 could be completely tax-free for one person. For another person it could be taxed at 15%. It just depends on how money they make in total.
Some people think that if they are in the 24% tax bracket for their income then their long-term capital gains are also taxed at 24%.. That is not true. Long-term capital gains have their tax schedule. It is separate, from the tax brackets that apply to the money people earn from their jobs. Long-term capital gains are taxed differently using their special rates of 0%, 15% and 20%.
Holding Period
To get long-term treatment you usually need to own something for than a year. This means you have to own it for than 365 days or 366 days if it is a leap year. You have to count from the day after you buy it to the day you sell it. If you sell it on or before one year is up you will have to pay short-term taxes. This is the rate you pay on the money you earn from your job. If you wait one more day it can make a big difference, in how much tax you have to pay.
Current Federal Long-Term Capital Gains Tax Rates
The rules for the 2026 tax year are important to know. This is the income you earn in 2026. Report on your tax return in 2027. The Internal Revenue Service made these rules in something called Revenue Procedure 2025-32. These numbers are for your income.
| Filing Status | 0% Rate Range | 15% Rate Range | 20% Rate Range |
| Single | Up to $49,450 | $49,451–$545,500 | Above $545,500 |
| Married Filing Jointly | Up to $98,900 | $98,901–$613,700 | Above $613,700 |
| Head of Household | Up to $66,200 | $66,201–$579,600 | Above $579,600 |
| Married Filing Separately | Up to $49,450 | $49,451–$306,850 | Above $306,850 |
These brackets change a bit every year because of inflation so the exact amounts of money are different each year. You should always make sure you are looking at the tax year before you use a certain limit.
How to Calculate Long-Term Capital Gains
- Determine your sale proceeds — what you received from selling the asset.
- Determine your adjusted cost basis — generally your purchase price plus qualifying adjustments.
- Subtract basis from proceeds to find your capital gain (or loss).
- Confirm the holding period qualifies as long-term (more than one year).
- Apply any capital losses that offset the gain.
- Add the net long-term gain to your other taxable income to see which rate bracket(s) it falls into.
- Apply the applicable 0%, 15%, or 20% rate to the portion of the gain in each bracket.
- Check whether the Net Investment Income Tax applies based on your total income.
Long-Term Capital Gains Tax Formula
Capital Gain = Amount Realized − Adjusted Basis
- Amount realized is your sale proceeds, net of applicable selling costs.
- Adjusted basis is generally your original cost plus qualifying additions (like reinvested dividends or capital improvements) and minus certain reductions (like depreciation claimed on rental property).
A simplified way to estimate the tax on a single gain is:
Estimated Long-Term Capital Gains Tax = Taxable Long-Term Gain × Applicable Rate
This simplified formula is useful for quick estimates, but it isn’t a complete tax-return calculation. It doesn’t account for how the gain stacks across multiple brackets, other income, deductions, capital losses from other transactions, or additional taxes like the NIIT.

Required Inputs
| Input | What It Means |
| Purchase Price / Cost Basis | What you paid for the asset, adjusted for qualifying additions |
| Sale Price / Proceeds | What you received when you sold it |
| Holding Period | Confirms whether the gain is long-term or short-term |

How to Interpret the Result
The calculator separates several figures: your sale proceeds, your capital gain, your taxable gain after losses, and your estimated tax. Treat the estimated tax as a planning number. Your actual federal tax liability on a real return can differ due to other income, itemized deductions, capital-loss carryovers from prior years, additional taxes, and state taxes the calculator doesn’t include. If a result looks off, double-check the sale price, cost basis, holding period, filing status, and income entered.
Capital Losses
A capital loss occurs when you sell an asset for less than your adjusted basis. Capital losses can offset capital gains realized in the same tax year — long-term losses offset long-term gains, and short-term losses offset short-term gains, with any excess of one type applying to the other. If total losses exceed total gains, up to $3,000 per year ($1,500 if married filing separately) of the excess can offset ordinary income, with any remaining loss carried forward to future tax years.
Short-Term vs. Long-Term Capital Gains
| Feature | Short-Term Capital Gain | Long-Term Capital Gain |
| Holding period | One year or less | More than one year |
| Federal tax treatment | Ordinary income rates (10%–37%) | Preferential rates (0%, 15%, 20%) |
| Rate depends on | Taxable income and ordinary brackets | Taxable income, filing status, and gain thresholds |
| Typical impact | Usually higher tax on the same dollar of gain | Usually lower tax on the same dollar of gain |
State Capital Gains Taxes
The amount of money you pay for long-term capital gains does not decide how much tax you have to pay in total. What happens with capital gains is different in each state. Some states treat capital gains like the money you earn from a job and tax it that way. Some states do not tax the money people make all.. Then there are states like Washington that have a special tax, on capital gains.
Net Investment Income Tax
Higher-income taxpayers might have to pay a 3.8% Net Investment Income Tax (NIIT) on net investment income. Such, as capital gains, interest, dividends and rental income. When their modified adjusted gross income goes over $200,000 (for single people or heads of households) or $250,000 (for married couples filing jointly). These limits are set by law. Do not change with inflation.
Common Mistakes
- Confusing sale proceeds with capital gain. Selling an asset for $50,000 doesn’t mean the gain is $50,000 — basis matters.
- Forgetting cost basis adjustments. Reinvested dividends and capital improvements can raise your basis over time.
- Assuming one flat rate applies to the whole gain. Gains can stack across the 0%, 15%, and 20% ranges.
- Ignoring the holding period. Selling even a day early can shift a gain from long-term to short-term treatment.
- Ignoring capital losses. Losses from the same year, or carried forward from prior years, can reduce your taxable gain.
- Ignoring state taxes. A federal estimate is not your total tax liability in states that tax capital gains.
- Using outdated brackets. Thresholds are adjusted annually — confirm you’re using the correct tax year.
- Treating the calculator as a finished tax return. It’s an estimate, not a filing document.
Limitations
This calculator provides a federal estimate based on the information entered. It generally doesn’t account for multiple transactions in the same year, capital-loss carryovers from prior years, state and local taxes, special asset rules (such as collectibles or qualified small business stock), or deductions and credits elsewhere on your return. Use the estimate for planning purposes, and confirm important figures with current IRS guidance or a qualified tax professional.

Conclusion
When you hold onto something for a time you might pay less tax on the money you make from it. This is called long-term capital gains tax. If you own an asset for than a year you usually get a better tax rate. You might pay 0%, 15% or 20% tax on the money you make of the tax rate you pay on the money you earn from your job. However the tax rate you pay still depends on how money you make and how you file your taxes.
You need to know two things to figure out how much tax you will pay: what you paid for the asset and how long you have owned it. These two things can change how tax you pay so it is a good idea to double check them. You can use the calculator on MultiCalculators.com to get an idea of how tax you will pay.. You should also look at what the IRS says or talk to a tax professional to make sure you are doing everything right.
