Bitcoin is property in the US. Here is exactly what you owe when you sell, trade, or spend it — and how to report it correctly in 2026.
In the US, Bitcoin is property, not currency. Every time you sell, trade, or spend Bitcoin, you have a taxable event. You owe capital gains tax on the profit. This applies whether you made the transaction on Coinbase, a DEX, or a peer-to-peer swap.
The IRS has been clear on this since 2014. Crypto tax enforcement has intensified significantly since then. This guide explains what you owe, when you owe it, and how to report it correctly.
The IRS classifies Bitcoin as property (Notice 2014-21, confirmed in Rev. Rul. 2023-14). This means Bitcoin is subject to the same tax rules as stocks, real estate, and other capital assets.
Two types of taxable events:
Non-taxable events:
How long you held your Bitcoin before selling determines the tax rate:
Taxed as ordinary income — at your marginal federal income tax rate.
| 2026 Federal Income Tax Brackets | Rate |
|---|---|
| $0 - $11,925 (single) | 10% |
| $11,926 - $48,475 | 12% |
| $48,476 - $103,350 | 22% |
| $103,351 - $197,300 | 24% |
| $197,301 - $250,525 | 32% |
| $250,526 - $626,350 | 35% |
| Over $626,350 | 37% |
Taxed at preferential long-term capital gains rates.
| 2026 Long-Term Capital Gains Rate | Single Filers | Married Filing Jointly |
|---|---|---|
| 0% | Up to $48,350 | Up to $96,700 |
| 15% | $48,350 - $533,400 | $96,700 - $600,050 |
| 20% | Over $533,400 | Over $600,050 |
The key insight: Holding Bitcoin for over one year before selling cuts your maximum federal tax rate from 37% to 20%. On large gains, this difference is enormous.
Formula: Capital Gain = Sale Price − Cost Basis
Cost basis is what you paid for the Bitcoin plus any fees you paid to acquire it.
Example:
Example with a loss:
When you have purchased Bitcoin multiple times at different prices, you need to choose an accounting method to determine which coins you are "selling."
| Method | Description | Best When |
|---|---|---|
| FIFO (First In, First Out) | Oldest coins sold first | Default if you don't specify |
| LIFO (Last In, First Out) | Newest coins sold first | Can reduce gains in rising markets |
| HIFO (Highest In, First Out) | Highest-cost coins sold first | Minimizes gains (most popular for tax optimization) |
| Specific Identification | You choose which specific coins to sell | Maximum flexibility; requires records |
Important: The IRS requires you to consistently apply your chosen method. You cannot switch methods to cherry-pick the best outcome per transaction. HIFO is legal and widely used to minimize taxable gains.
Most crypto tax software (Koinly, CoinTracker, TaxBit, ZenLedger) supports all of these methods and will calculate your optimal basis automatically.
The most common event. Coinbase, Kraken, Gemini, and other exchanges issue 1099-DA forms (starting tax year 2025) showing your proceeds. You still need to calculate your cost basis and report gains/losses on Form 8949.
Each purchase creates a new lot with its own cost basis and purchase date. If you buy $100 of Bitcoin every week for a year, you have 52 separate lots to track. Tax software handles this automatically.
Trading BTC for ETH, stablecoins, or any other crypto is a taxable sale of Bitcoin at the market price. The gain is the fair market value of what you received minus your Bitcoin cost basis.
Paying for goods or services with Bitcoin is a taxable sale. If you bought a $500 laptop with Bitcoin you purchased for $300 worth of BTC, you have a $200 capital gain.
If you receive Bitcoin as income — payment for freelance work, mining rewards, staking rewards, referral bonuses — it is taxed as ordinary income at its fair market value when received. You then hold it with that value as your new cost basis.
Inherited Bitcoin receives a stepped-up cost basis — the fair market value on the date of death. This eliminates all unrealized gains. It is one of the most significant tax benefits for long-term Bitcoin holders. See what to do when you inherit Bitcoin.
Form 8949 — Sales and Other Dispositions of Capital Assets Report every Bitcoin sale/trade here: date acquired, date sold, proceeds, cost basis, gain or loss.
Schedule D — Capital Gains and Losses Summarizes your Form 8949 totals and flows into Form 1040.
Schedule 1 — Additional Income Report Bitcoin income (mining rewards, payment received) as "Other Income" here.
AnsweringQuestion on Form 1040 Since 2019, the first page of Form 1040 asks: "At any time during [year], did you receive, sell, exchange, or otherwise dispose of any digital assets?" Answer Yes if you had any transactions. Answer No only if your only activity was buying Bitcoin with no disposals.
Starting with tax year 2025, exchanges are required to issue Form 1099-DA to customers reporting gross proceeds. Brokers began tracking cost basis for holdings acquired after January 1, 2026.
Key point: 1099-DA shows proceeds but not always your correct cost basis — especially for coins transferred in from other wallets. You must track your own cost basis for accurate reporting.
Bitcoin's volatility creates tax-loss harvesting opportunities unavailable in stocks.
Wash sale rules: The IRS wash sale rule prevents you from claiming a loss if you buy the same security within 30 days before or after selling at a loss. As of 2026, this rule does NOT apply to crypto/Bitcoin. (Congress has proposed extending it to crypto but has not yet passed this.)
This means you can:
This is legal and widely practiced. The loss offsets other capital gains (or up to $3,000 in ordinary income per year). You maintain your Bitcoin position. Note: if the wash sale rule is extended to crypto in future legislation, this strategy would be eliminated.
Capital gains within a Roth IRA are tax-free. Capital gains in a Traditional IRA are tax-deferred. If you hold Bitcoin in an IRA, you do not owe capital gains tax on appreciation within the account.
See Bitcoin IRA explained for setup options and Bitcoin ETFs vs direct Bitcoin for comparing Bitcoin ETFs in standard IRAs.
State capital gains taxes apply in most US states. Key points:
See Bitcoin tax by state for the full breakdown.
The US taxes residents on worldwide income regardless of where Bitcoin is held or traded. See Bitcoin capital gains tax by country for global tax treatment.
For US citizens living abroad: you still owe US taxes. Foreign tax credits may reduce double taxation but do not eliminate US filing requirements.
Manual tracking of Bitcoin transactions is error-prone and time-consuming. Dedicated crypto tax software solves this:
| Software | Best For | Cost |
|---|---|---|
| Koinly | Most users, clean UI | $49-199/year |
| CoinTracker | Large portfolios, CPA-ready | $59-299/year |
| TaxBit | Advanced users, enterprises | $50-500/year |
| ZenLedger | TurboTax integration | $49-999/year |
| CryptoTrader.Tax | Simple, Coinbase-connected | $49-299/year |
All of these connect to exchanges via API or CSV import, calculate cost basis using your chosen method, and generate ready-to-file Form 8949 and Schedule D reports.
Do I owe taxes if I just hold Bitcoin without selling? No. Simply holding Bitcoin in any wallet (exchange, hardware wallet, self-custody) is not a taxable event. You only owe tax when you sell, trade, or spend.
What if I forgot to report Bitcoin on previous tax returns? File amended returns (Form 1040-X) for any years where you failed to report crypto transactions. The IRS has increased enforcement significantly, and voluntary disclosure is far better than an audit finding unreported income.
Does the IRS know about my Bitcoin? Increasingly yes. Exchanges report to the IRS via 1099-DA forms. The IRS has issued John Doe summonses to Coinbase and other exchanges for customer data. Chain analytics companies work with the IRS to identify unreported transactions.
What if I lost Bitcoin in an exchange hack or lost my keys? The IRS has limited guidance on this. A theft loss may be deductible if the theft is from a criminal act. Lost-key situations are more complex — consult a CPA who specializes in crypto.
Do I need to report Bitcoin in my foreign exchange accounts? Yes. Foreign financial accounts holding Bitcoin may require FBAR (FinCEN 114) and Form 8938 (FATCA) filing if thresholds are met ($10,000 for FBAR, higher for FATCA).
Bitcoin taxes are straightforward in principle: you owe capital gains tax when you sell or trade, calculated as sale price minus cost basis. The key variables are your holding period (short-term vs long-term), your income level (determines your rate), and your cost basis method (HIFO minimizes taxes for most holders).
Use crypto tax software to track your transactions, hold Bitcoin for over one year when possible to get long-term rates, consider tax-loss harvesting during dips, and hold Bitcoin in a Roth IRA for the ultimate tax advantage. If your holdings are significant, work with a CPA who understands crypto.
