Crypto Long-Term Capital Gains Calculator

About the Crypto Long-Term Capital Gains Calculator

Long-term capital gains on cryptocurrency apply when you sell or trade digital assets held for more than one year. The U.S. tax code rewards patient investors with preferential rates of 0%, 15%, or 20% — significantly lower than the ordinary income rates applied to short-term gains. Your specific rate depends on your taxable income and filing status.

This calculator estimates the federal long-term capital gains tax on your crypto profits. Enter your sale proceeds, cost basis, taxable income, and filing status to see the applicable LTCG rate and tax owed. The calculator uses current income thresholds to determine whether you fall into the 0%, 15%, or 20% bracket.

For investors who practice a buy-and-hold strategy with Bitcoin, Ethereum, or other cryptocurrencies, understanding long-term rates is essential for tax planning. The difference between a 37% short-term rate and a 15% long-term rate on a $50,000 gain is $11,000 in tax savings — a compelling reason to think twice before selling early.

When This Page Helps

Knowing your long-term capital gains tax rate helps you decide when to sell. If you're close to the one-year holding threshold, waiting a few extra days could save thousands in taxes. This calculator also reveals whether your income level qualifies you for the 0% rate, which many taxpayers overlook. Use it to plan sales across tax years and maximize after-tax returns on your crypto investments.

How to Use the Inputs

1. Enter the total sale proceeds from your crypto disposition.
2. Enter the cost basis (original purchase price plus fees).
3. Enter your estimated taxable income for the year (excluding the gain).
4. Select your filing status.
5. View the long-term gain, applicable LTCG rate, and estimated tax.
6. Compare results with the short-term calculator to see potential savings from holding longer.

Example Calculation

Tips & Best Practices

• The 0% LTCG rate applies to single filers with total income up to about $48,350 — strategically realize gains in low-income years.
• Track your acquisition date carefully; one day short of a year means the full gain is taxed as ordinary income.
• The 3.8% Net Investment Income Tax (NIIT) may apply on top of LTCG rates for high earners.
• Gifting appreciated crypto to family members in lower brackets can shift the tax burden to a lower rate.
• Tax-loss harvesting can offset long-term gains and reduce your overall tax liability.
• State taxes may add additional tax on top of the federal LTCG rate.

Understanding the Three LTCG Brackets

The 0% bracket is often overlooked. Single filers with taxable income under roughly $48,350 (including the gain) pay zero federal tax on long-term crypto gains. Married couples filing jointly have a threshold of about $96,700. This is powerful for early retirees or those in transition years between jobs.

Long-Term vs Short-Term: The Tax Savings

Consider a $50,000 crypto gain for someone in the 32% ordinary income bracket. Short-term tax would be $16,000 while long-term tax at 15% would be $7,500 — a savings of $8,500 simply by holding longer than one year. For larger gains, the savings grow proportionally.

Planning for the NIIT Surcharge

High-income investors must account for the 3.8% Net Investment Income Tax on top of their LTCG rate. At the 20% bracket plus NIIT, the effective federal rate is 23.8%. Strategies like charitable donations of appreciated crypto or Qualified Opportunity Zone investments can help mitigate this extra tax.

Frequently Asked Questions

• What are the long-term capital gains tax rates for crypto?

  For 2025, the rates are 0%, 15%, or 20% depending on your taxable income and filing status. Single filers pay 0% on gains if total taxable income is below approximately $48,350, 15% up to about $533,400, and 20% above that threshold.

• How long do I need to hold crypto for long-term treatment?

  You must hold the cryptocurrency for more than one year — specifically, at least one year and one day. The holding period begins the day after acquisition and ends on the disposal date. If you bought on January 1, 2025, the earliest date for long-term treatment is January 2, 2026.

• Does the 3.8% NIIT apply to crypto gains?

  Yes. The Net Investment Income Tax of 3.8% applies to crypto capital gains for single filers with modified adjusted gross income above $200,000 or married filing jointly above $250,000. This effectively raises the top long-term rate to 23.8%.

• Can I use long-term losses to offset short-term gains?

  Yes, but there is an ordering rule. Long-term losses first offset long-term gains. If there is a net long-term loss remaining, it then offsets net short-term gains. This netting process happens on Schedule D of your tax return.

• Is staking or mining income eligible for long-term rates?

  Staking and mining rewards are first taxed as ordinary income when received. If you later sell those tokens at a profit after holding them for more than one year, that subsequent gain qualifies for long-term capital gains rates. The initial income event is always ordinary income.

• What if my income varies year to year?

  If your income fluctuates, timing your crypto sales to low-income years can put you in a lower LTCG bracket or even the 0% bracket. This strategy is particularly useful for freelancers, retirees, or anyone with variable annual income.
