Crypto Tax Calculator: What You'll Actually Owe on Bitcoin and Other Gains

The IRS treats cryptocurrency as property, not currency. Every time you sell, trade, or spend crypto, you trigger a taxable event. Most crypto investors significantly underestimate what they owe.

How Crypto Gains Are Taxed

The tax rate depends on two things: your income level and how long you held the asset.

Short-term capital gains: Held 1 year or less. Taxed as ordinary income at your marginal federal tax rate (10% to 37%).

Long-term capital gains: Held more than 1 year. Taxed at preferential rates (0%, 15%, or 20% depending on income).

This distinction is worth real money. On a $13,000 gain, the difference between short-term and long-term treatment can be thousands of dollars.

2026 Long-Term Capital Gains Rates

| Filing Status | 0% Rate | 15% Rate | 20% Rate | |--------------|---------|----------|----------| | Single | Up to $47,025 | $47,026 to $518,900 | Over $518,900 | | Married Filing Jointly | Up to $94,050 | $94,051 to $583,750 | Over $583,750 | | Head of Household | Up to $63,000 | $63,001 to $551,350 | Over $551,350 |

Real Example: $5,000 into Bitcoin, Sold for $18,000

You bought $5,000 of BTC. You sold it for $18,000. Your gain is $13,000.

Scenario 1: Held less than 1 year (short-term)

| Income Level | Marginal Rate | Tax on $13,000 Gain | |-------------|--------------|---------------------| | $40,000 total income | 12% | $1,560 | | $80,000 total income | 22% | $2,860 | | $120,000 total income | 24% | $3,120 | | $200,000 total income | 32% | $4,160 |

Scenario 2: Held more than 1 year (long-term)

| Income Level | Long-Term Rate | Tax on $13,000 Gain | |-------------|---------------|---------------------| | $40,000 total income | 0% | $0 | | $80,000 total income | 15% | $1,950 | | $120,000 total income | 15% | $1,950 | | $200,000 total income | 15% | $1,950 | | $600,000 total income | 20% | $2,600 |

If your total income is $80,000 and you held Bitcoin for more than 1 year, you pay $1,950 in taxes vs $2,860 for short-term. That's a $910 difference just by waiting a few extra months to cross the 1-year mark.

What Triggers a Taxable Event

Taxable events include:

• Selling crypto for US dollars
• Trading one cryptocurrency for another (BTC to ETH is a taxable event)
• Using crypto to buy goods or services
• Receiving crypto as payment for work (ordinary income at receipt)
• Receiving staking rewards or mining income (ordinary income at receipt)

Not taxable:

• Buying crypto with dollars
• Holding crypto
• Transferring crypto between your own wallets
• Gifting crypto (though gift tax rules apply above $18,000 in 2026)

The Wash Sale Rule Does NOT Apply to Crypto

This is one of crypto's only tax advantages over stocks. The wash sale rule prevents stock investors from selling a position at a loss, claiming the loss, and immediately rebuying the same stock.

For crypto, this rule does not currently apply. You can sell Bitcoin at a loss on December 31, realize the tax loss, and rebuy immediately on January 1. You maintain your position while locking in the tax deduction.

Note: Congress has periodically considered extending wash sale rules to crypto. Check current law before executing a strategy that depends on this treatment.

Tax-Loss Harvesting With Crypto

Tax-loss harvesting means selling losing positions to generate capital losses that offset gains.

If you have $13,000 in BTC gains and $8,000 in ETH losses, you can sell the ETH to offset $8,000 of the BTC gain. You'd only owe taxes on the remaining $5,000 of net gain.

Up to $3,000 of net capital losses beyond gains can offset ordinary income per year. Excess losses carry forward indefinitely to future tax years.

How to Track Your Crypto Cost Basis

Your cost basis is what you paid for the crypto. Gains = sale price minus cost basis.

If you bought Bitcoin in multiple lots at different prices, you need to track each lot. Common methods:

• FIFO (First In, First Out): Assumes you sell the oldest coins first. Default in most cases.
• Specific identification: You identify exactly which coins you're selling. Can be used to minimize gains by selling high-basis lots first.

Keep records of every purchase: date, amount of crypto, price paid. Your exchange should provide transaction history, but don't rely solely on that. Download and save it.

DeFi and NFTs

DeFi transactions (swaps, liquidity provision, yield farming) are all taxable events. NFT sales are taxed as capital gains. NFT creation and sales by the creator may be taxed as ordinary income. This space has limited IRS guidance but the principles remain: you owe tax on gains.
