If you bought, sold, swapped, staked, or earned crypto in 2025, the IRS expects to hear about it on your 2026 tax return. Crypto tax is one of the most misunderstood areas in personal finance — and one of the most heavily enforced. With Form 1099-DA arriving for the first time and the question on the front of Form 1040 still asking every taxpayer about digital assets, getting this right matters.
This guide covers everything a US taxpayer needs to know for the 2026 filing season: what triggers a taxable event, current tax rates, how to report each kind of activity, common mistakes that draw IRS letters, and the tools that make filing manageable.
How the IRS Treats Cryptocurrency
The IRS classifies cryptocurrency as property, not currency. That single classification, set in Notice 2014-21 and reaffirmed every year since, is the source of almost every quirk in US crypto taxation. When you sell stock, you owe capital gains tax. Same rule for crypto. When you barter property for goods, you trigger a taxable event. Same rule for paying your coffee in Bitcoin.
This is why simply spending crypto can create a tax bill — even when you have not converted to dollars.
Taxable vs Non-Taxable Events
You only owe tax when a taxable event occurs. Knowing the difference saves a lot of paperwork.
Taxable events
- Selling crypto for USD (or any fiat currency)
- Trading one crypto for another (BTC → ETH is a sale of BTC)
- Spending crypto on goods or services
- Receiving crypto as payment for work, freelance income, or services
- Receiving crypto from staking, mining, airdrops, or interest accounts
- Receiving crypto from a hard fork (when you get new coins)
Non-taxable events
- Buying crypto with USD and holding it
- Transferring crypto between wallets you own
- Gifting crypto under the annual exclusion limit ($19,000 per recipient in 2025)
- Donating crypto to a qualified 501(c)(3) charity
- Borrowing against your crypto (DeFi loans are not sales)
The trickiest one is crypto-to-crypto trades. New investors are often shocked to learn that swapping ETH for SOL is a taxable disposal of ETH at fair market value, even though no dollars changed hands.
Capital Gains Tax Rates for 2026
How much you owe depends on how long you held the asset and your total taxable income.
Short-term capital gains (held one year or less)
Taxed as ordinary income at your marginal federal rate:
| 2025 Income (Single) | 2025 Income (Married, Joint) | Federal Rate |
|---|---|---|
| Up to $11,925 | Up to $23,850 | 10% |
| $11,926 – $48,475 | $23,851 – $96,950 | 12% |
| $48,476 – $103,350 | $96,951 – $206,700 | 22% |
| $103,351 – $197,300 | $206,701 – $394,600 | 24% |
| $197,301 – $250,525 | $394,601 – $501,050 | 32% |
| $250,526 – $626,350 | $501,051 – $751,600 | 35% |
| Over $626,350 | Over $751,600 | 37% |
Long-term capital gains (held more than one year)
Preferential rates that reward longer holding:
| 2025 Taxable Income (Single) | 2025 Taxable Income (Married, Joint) | LTCG Rate |
|---|---|---|
| Up to $48,350 | Up to $96,700 | 0% |
| $48,351 – $533,400 | $96,701 – $600,050 | 15% |
| Over $533,400 | Over $600,050 | 20% |
High earners may also owe a 3.8% Net Investment Income Tax (NIIT) on top of long-term capital gains and other passive income, kicking in above $200,000 (single) or $250,000 (joint).
The single most valuable move for most retail investors is simple: hold for more than 12 months before selling when possible. The difference between 24% short-term and 15% long-term is meaningful at any size.
Income Tax on Crypto Earnings
Some crypto activity is taxed as ordinary income at the moment you receive it, not as a capital gain.
| Activity | Tax Treatment |
|---|---|
| Mining rewards | Ordinary income at fair market value when mined |
| Staking rewards | Ordinary income at fair market value when received |
| Airdrops | Ordinary income at fair market value when claimable |
| Hard forks | Ordinary income when new coins land in your wallet |
| Interest from CeFi/DeFi | Ordinary income |
| Crypto wages | Wages — subject to W-2 withholding or self-employment tax |
| Referral and reward bonuses | Ordinary income |
There is a critical second step many people miss: when you later sell that staking reward or airdropped token, you also owe capital gains tax on any change in value between the day you received it (your cost basis) and the day you sold. Crypto is taxed at receipt, then again on disposal — two events, not one.
Form 1099-DA and the New Reporting Regime
Starting with the 2025 tax year (filed in 2026), US-based exchanges and brokers issue Form 1099-DA — a new IRS form specifically for digital assets. It reports your gross proceeds for each sale.
What this means:
- The IRS now receives a copy of every reportable transaction directly from Coinbase, Kraken, Gemini, and other US brokers
- Cost basis reporting on 1099-DA is partial in 2025 and becomes full in 2026
- Mismatches between 1099-DA and your return will trigger automated CP2000 letters
You cannot ignore this. Even small transactions are visible to the IRS. Even DeFi and self-custody activity will progressively come into reporting scope as broker rules expand.
How to Report Crypto on Your Tax Return
Your federal return needs three things:
1. Answer the Digital Asset question on Form 1040
Right at the top of Form 1040 is the question: “At any time during 2025, did you (a) receive (as a reward, award, or payment for property or services); or (b) sell, exchange, or otherwise dispose of a digital asset (or a financial interest in a digital asset)?”
Buying with USD only and holding does not require a “Yes.” Almost everything else does. Lying here is a separate offense from the underlying tax issue and the IRS treats it seriously.
2. Report capital gains on Form 8949 and Schedule D
Form 8949 lists every disposal: what you sold, when you bought it, when you sold it, your cost basis, your proceeds, and your gain or loss. Each line is one transaction.
Schedule D summarises Form 8949 and pulls your total short-term and long-term capital gains into your overall return.
3. Report ordinary income on Schedule 1 (or Schedule C)
- Hobbyist staking, airdrops, and referral rewards → Schedule 1, line 8v (“Digital assets received as ordinary income”)
- Mining as a business or self-employed crypto work → Schedule C with associated self-employment tax
Cost Basis Methods
When you sell only part of a coin position, which units did you sell? The IRS allows several methods:
Specific identification typically minimises tax in volatile years, but you must have complete, contemporaneous records showing exactly which units you sold. Reputable crypto tax software handles this automatically.
Important: starting with the 2025 tax year, the IRS requires cost basis to be tracked per wallet or account (Revenue Procedure 2024-28), not pooled across all your holdings. If you used a universal cost basis method in prior years, you needed to allocate your basis to each wallet by January 1, 2025.
DeFi, NFTs, and Edge Cases
DeFi swaps
Swapping on Uniswap, Curve, 1inch, or any DEX is a taxable disposal — same as a centralised exchange trade. Gas fees can typically be added to cost basis or deducted from proceeds.
Liquidity providing
Depositing tokens into a liquidity pool is treated by most tax practitioners as a taxable trade (you receive an LP token in return). Withdrawing is another taxable event. This area has limited official IRS guidance, so consistency with a defensible position matters.
Lending and borrowing
Borrowing against crypto collateral is not a taxable event, exactly like a margin loan against stocks. Liquidation of your collateral is. Lending out crypto on Aave or Compound, and earning interest, generates ordinary income.
NFTs
NFTs are property like other crypto. Buying with ETH is a disposal of ETH. Selling an NFT is a capital gain or loss. The IRS may treat collectible NFTs at the higher 28% collectibles rate — guidance is still evolving (Notice 2023-27).
Wrapped tokens and bridges
Wrapping ETH to wETH or bridging between chains is arguably not a disposal because economic ownership is unchanged, but the IRS has not issued definitive guidance. Many tax preparers and software default to treating these as non-taxable transfers; document your approach.
Losses and Tax-Loss Harvesting
Capital losses can offset capital gains dollar-for-dollar. Up to $3,000 of net losses ($1,500 if married filing separately) can offset ordinary income each year, with the remainder carried forward indefinitely.
Crypto’s biggest tax advantage right now: the wash-sale rule does not apply to digital assets. You can sell a coin at a loss, immediately buy it back, harvest the loss for tax purposes, and keep your position. The Treasury has proposed extending wash-sale rules to crypto multiple times — expect this loophole to close eventually, but as of the 2025 tax year it remains open.
State Taxes
Federal tax is only half the story. Most states tax crypto gains at their own income tax rate (0% in Texas, Florida, Wyoming, and a few others; up to 13.3% in California). A handful — like New Hampshire — tax only certain investment income. Check your state’s department of revenue for crypto-specific guidance.

When You Need a CPA
Software handles 95% of returns well. Bring in a crypto-savvy CPA when you have:
- Six-figure annual gains or losses
- Active DeFi yield farming, leveraged positions, or perpetuals
- Lost or stolen crypto (theft loss claims are narrow)
- Crypto received as part of a job, ICO, or token grant
- Estate planning or significant gifting
- An IRS notice (CP2000, CP2501) that disputes your reporting
A good crypto CPA can save many times their fee through better basis selection, classification of edge cases, and audit defence if it ever comes to that.
Frequently Asked Questions
Do I owe tax if I just hold crypto and never sell?
No. Buying and holding is not a taxable event. Tax kicks in only on disposal, swap, spend, or receipt of new crypto income.
What if I lost money on crypto?
Report the losses. They reduce your taxable gains and up to $3,000 of ordinary income each year, with carry-forward.
Are stablecoins taxed?
Yes. USDC, USDT, and DAI are all crypto in IRS eyes. Trading them generates a tiny capital gain or loss, and earning yield on them is ordinary income.
Do I have to pay tax on airdrops I never claimed?
The IRS position is that you owe tax when you have dominion and control — when you can dispose of the tokens. If you never claimed them and they were never moved to your wallet, you do not have dominion. Once you claim, the clock starts.
What happens if I haven’t reported in past years?
File amended returns. The IRS Voluntary Disclosure program is available for serious cases. Penalties for accuracy-related errors are 20% of underpayment; for fraud they can be 75% plus criminal exposure. Acting before the IRS contacts you almost always reduces penalties.
Are crypto gifts taxable?
Gifts up to $19,000 per recipient per year (2025) require no gift tax. The recipient takes your cost basis. Larger gifts use up your lifetime exclusion (currently around $13.99 million per individual).
What about crypto donated to charity?
Donations to qualified 501(c)(3) charities are deductible at fair market value if held over one year, with no capital gains tax due. This is one of the most powerful planning moves in crypto — donating appreciated coin instead of cash.
The Practical Filing Checklist
- Pull CSV exports from every exchange you used in 2025
- Connect your self-custody wallets to your tax tool via address (read-only)

- Reconcile your tool’s output against any 1099-DA you received
- Choose your cost basis method (and stick with it)
- Generate Form 8949
- Import into TurboTax / H&R Block / your CPA’s software, or attach to a paper return
Crypto tax is not as scary as it looks once the moving parts are clear. Get your 2025 records in order now, before the April 15, 2026 deadline becomes a problem.
