The Complete U.S. Crypto Tax Guide (2026)

How the IRS classifies cryptocurrency

The IRS first articulated cryptocurrency's tax classification in Notice 2014-21: crypto is property, not currency. That position has held across every subsequent piece of IRS guidance, including the 2024 final broker-reporting regulations.

The property classification is the single most important fact about U.S. crypto taxation. It means:

• Buying crypto with U.S. dollars and holding it is not a taxable event – there's no gain to recognize until you do something with it.
• Selling crypto for dollars, swapping it for another token, or spending it on goods or services is a disposition that produces a capital gain or loss.
• Earning crypto – through work, staking, mining, airdrops, hard forks, or any other receipt – is ordinary income equal to the fair market value of what you received on the date you received it.
• There is no like-kind exchange treatment for crypto. Section 1031 was limited to real property starting in 2018.

Subsequent guidance has filled in the details: Rev. Rul. 2019-24 addressed hard forks, Rev. Rul. 2023-14 addressed staking, and Notice 2023-27 proposed look-through treatment for NFTs as collectibles. None of those changed the underlying property classification – they just applied it to specific situations.

When crypto becomes taxable

For most taxpayers, crypto creates two distinct kinds of tax events: dispositions (which produce capital gain or loss) and receipts (which produce ordinary income). Businesses that hold crypto as inventory or whose primary activity involves disposing of digital assets may recognize ordinary gains and losses instead of capital gains and losses on the dispositions.

Dispositions

A disposition happens when you part with crypto, including:

• Selling crypto for U.S. dollars or another fiat currency
• Swapping one cryptocurrency for another (every token swap is two separate steps: a sale of token A and a purchase of token B)
• Spending crypto on goods or services
• Selling an NFT
• Most DeFi swaps, including liquidity pool entries and exits, depending on the protocol mechanics

The gain or loss equals proceeds minus your cost basis. Proceeds is the fair market value of what you received (in U.S. dollars) at the moment of the disposition. Cost basis is what you originally paid to acquire the disposed token (plus any acquisition gas fees added to basis).

Receipts

A receipt happens when crypto comes to you through means other than a direct fiat currency purchase, including:

• Staking rewards (per Rev. Rul. 2023-14)
• Mining rewards, including block rewards and transaction fees
• Airdrops, though timing and specific facts may affect when income is recognized
• New tokens from a hard fork (per Rev. Rul. 2019-24)
• Crypto received as payment for goods or services
• DeFi yield, governance token receipts, and rebase rewards, though IRS guidance in this area continues to evolve
• Referral bonuses, promotional bonuses, and play-to-earn rewards, under general income recognition principles

The income recognized equals the fair market value at the moment you gain dominion and control, typically when the tokens are credited to your wallet and are transferable, sellable, or otherwise usable. That fair market value also becomes your cost basis when you later dispose of those tokens.

Crypto tax rates

Crypto gains are taxed at the rate that matches the type of event and the holding period.

Short-term capital gains

If the disposed crypto was held for one year or less, the gain is short-term and taxed at ordinary income rates under applicable federal and state law. The rate varies depending on the taxpayer's filing status, taxable income, and entity type.

Long-term capital gains

If the crypto was held for more than one year before disposal, the gain is long-term and generally taxed at preferential federal rates for eligible taxpayers. C corporations do not benefit from a separate long-term capital gains rate. State tax and the Net Investment Income Tax (NIIT) may also apply.

Collectible rate for NFTs

NFTs that meet the IRS's definition of a "collectible" under IRC § 408(m) may be subject to a higher long-term capital gains rate. Per Notice 2023-27, the IRS applies a "look-through" analysis to determine collectible status based on what the NFT represents or grants rights to.

Ordinary income

Income receipts such as staking, mining, airdrops, hard forks, and crypto received as payment are taxed at the applicable ordinary income rate. Activities conducted as a trade or business may also give rise to self-employment tax or payroll obligations depending on entity type.

Cost basis and the wallet-by-wallet rule

Cost basis is what you paid to acquire the crypto. It's what you subtract from your proceeds at sale to determine your gain or loss. For 2025 and later years, the rules for how basis is tracked across your accounts have meaningfully changed.

The pre-2025 universal pooling approach

Historically, many taxpayers tracked basis across all their wallets as a single pool – first-in-first-out across the entire portfolio, regardless of where each unit lived. This "universal pooling" approach was practical but not strictly required by any IRS guidance.

The 2025+ wallet-by-wallet rule

Under Rev. Proc. 2024-28, effective for tax years beginning on or after January 1, 2025, taxpayers must track basis wallet-by-wallet. The same token held in two wallets has two separate basis pools, and an accounting-method election (such as specific identification or HIFO) made in one wallet does not bind another.

The revenue procedure provides a one-time safe harbor for allocating "unused basis" across wallets as of January 1, 2025. Taxpayers can either specifically identify units or allocate by an acceptable global method. Once made, the allocation is binding for all purposes.

FIFO, HIFO, and specific identification

Within a wallet, the IRS default is First-In, First-Out (FIFO) – the earliest tokens acquired are treated as the first ones sold. With adequate records, you can specifically identify which units are sold, which enables strategies like Highest-In, First-Out (HIFO) that select higher-basis tokens first to minimize gain.

How specific activities are taxed

Different on-chain activities map to different tax treatments. Below is the quick reference for the most common ones. Each has a dedicated FAQ entry with deeper detail.

Staking rewards

Ordinary income at fair market value on the date you gain dominion and control, per Rev. Rul. 2023-14. That fair market value becomes your cost basis for the rewarded tokens going forward. More →

Mining

Ordinary income at fair market value on receipt. Mining as a trade or business is subject to self-employment tax, but business expenses (electricity, equipment depreciation, hosting fees) are deductible. Hobby miners report income but cannot deduct expenses. More →

Airdrops and hard forks

Ordinary income at fair market value when you have dominion and control – typically when the tokens are credited to your wallet and you can transfer or sell them. Applies to marketing airdrops, retroactive distributions (UNI, ARB, OP, JUP), and hard-fork allocations alike. More →

NFTs

NFT sales produce a capital gain or loss on the difference between proceeds and cost basis. Holding period determines short-term or long-term treatment. Collectible-status NFTs may be subject to a higher long-term capital gains rate per IRC § 408(m) and Notice 2023-27. For creators, income from minting proceeds and royalties is generally treated as ordinary income. More →

DeFi

DeFi often produces multiple taxable events from a single user action. Swaps are dispositions. Liquidity provision can be a taxable disposition depending on protocol mechanics. Yield, governance tokens, and rebases are ordinary income. Wrapping and unwrapping tokens is technically a swap and arguably a disposition, though there's no definitive IRS guidance. More →

Wallet-to-wallet transfers

Not taxable. Moving crypto between wallets you control is not a disposition. But it still needs to be tracked, because misclassified transfers are the most common source of overstated gains in automated crypto tax software. More →

Spending crypto on goods or services

Taxable as a disposition. Even a small everyday purchase like buying a cup of coffee with crypto creates a capital gain or loss based on the difference between the purchase price and your cost basis in the crypto spent. More →

Reporting crypto on your tax return

Crypto reporting in the U.S. happens across several specific forms and one prominent yes/no question.

The digital asset question on Form 1040

Form 1040 includes a prominent yes/no question near the top: did you receive, sell, exchange, or otherwise dispose of a digital asset (or have a financial interest in one) during the tax year? Buying crypto with U.S. dollars and holding it is the only common scenario where the answer is "No." The question is signed under penalty of perjury, and the IRS has flagged it for enforcement attention. IRS detailed guide →

Form 8949 and Schedule D

Each individual crypto disposition is reported on Form 8949: asset, acquisition date, disposition date, proceeds, cost basis, gain or loss. Totals flow to Schedule D, then into Form 1040. Active traders can have hundreds or thousands of Form 8949 entries in a year – crypto tax software is essentially required to prepare them.

Form 1099-DA

Form 1099-DA is the new IRS information return that U.S. digital asset brokers (Coinbase, Kraken, Gemini, etc.) are required to issue beginning with the 2025 tax year. It reports gross proceeds in 2025, with cost basis reporting added in 2026. The form does not capture on-chain DeFi activity, peer-to-peer transfers, or self-custodied wallet activity – so taxpayers still need complete records of off-broker activity.

FBAR and FATCA

If you have foreign exchange accounts that exceed $10,000 in aggregate value at any point in the year, you're required to file the FBAR (FinCEN Form 114). Form 8938 may also apply for FATCA purposes above the relevant thresholds. As of current guidance, FinCEN has signaled crypto in foreign accounts may eventually be FBAR-reportable, but the rule has not been finalized.

Tax-loss harvesting with crypto

Because the IRS classifies digital assets as property rather than traditional securities, the wash sale rule under IRC § 1091, which disallows losses if an identical asset is repurchased within 30 days, does not explicitly apply to cryptocurrency. This provides unique flexibility for digital asset investors looking to offset capital gains by realizing strategic losses.

While the wash sale rule does not currently apply to digital assets, Congress has repeatedly proposed extending it, and this treatment could change in a future legislative session. Some tax professionals recommend maintaining a clear economic rationale for any tax-loss harvesting strategy as a matter of sound practice.

Capital loss rules at a glance

• Capital losses offset capital gains dollar-for-dollar across your entire portfolio
• For individual taxpayers, net capital losses exceeding gains may be deducted up to $3,000 against ordinary income annually
• Any remaining losses past the $3,000 threshold can be carried forward indefinitely to future tax years
• Different, more restrictive rules apply to corporate taxpayers

Special situations

A few common but tricky scenarios that don't fit the standard playbook.

Lost wallets

Losing access to a wallet (forgotten seed phrase, dead hardware wallet) does not create a tax event by itself – you still legally own the crypto, you just can't access it. The IRS has not issued specific guidance treating lost crypto as deductible. A worthlessness argument might apply in narrow circumstances, but the standard is high. More →

Stolen crypto and rug pulls

Personal theft losses are generally not deductible under the Tax Cuts and Jobs Act for tax years 2018–2025, except in federally declared disaster areas. Rug pulls where the token still trades may produce a deductible capital loss if you sell the remaining position. Investment scams may qualify as theft losses under IRC § 165 with high evidentiary requirements. More →

Bankrupt exchanges (FTX, Celsius, Voyager)

Crypto held in a bankrupt exchange is not deductible until you have a definitive loss – typically when the bankruptcy proceedings conclude and you receive your final distribution. The IRS recommended waiting after FTX. Once the recovery is known, the difference from your cost basis is generally a capital loss. More →

Gifts and inheritance

Gifts of crypto are not income to the recipient, but the recipient takes the donor's basis and holding period. A donor may owe gift tax if the gift exceeds the annual exclusion. Inherited crypto receives a stepped-up basis to fair market value at the date of death, with an automatic long-term holding period – generally the most favorable treatment available. More →

Charitable donations

Donating crypto held more than one year directly to a 501(c)(3) charity allows you to deduct the full fair market value and avoid capital gains tax on the appreciation. Donations over $500 require Form 8283; donations over $5,000 require a qualified appraisal. More →

Recordkeeping requirements

The Internal Revenue Code under IRC § 6001 requires every taxpayer to keep records sufficient to establish income, deductions, and credits. The burden of proof is on the taxpayer.

For crypto, that means a complete record of:

• Every wallet address you've used (with the chain they're on)
• Every exchange account you've held
• Every transaction across all of them, with date, asset, amount, U.S. dollar fair market value at the moment of the transaction, transaction hash where applicable, and the purpose (acquisition, disposition, transfer, income, expense)
• Cost basis for every unit currently held and every unit sold
• Any 1099 forms received (1099-DA, 1099-MISC, 1099-NEC, 1099-K)

For most taxpayers with non-trivial activity, this means using crypto tax software – not a spreadsheet – because the volume of transactions and the need to reconcile transfers across wallets quickly exceeds what manual tracking can produce reliably.

Common mistakes to avoid

The patterns we see most often when reviewing prior-year crypto returns:

1. Treating wallet-to-wallet transfers as sales

This is the single most common source of overstated gain. Crypto tax software defaults to treating an unidentified transfer-out as a sale at zero cost basis, which can inflate taxable gain by hundreds of thousands of dollars on an active account. Every transfer between your own wallets must be explicitly labeled as such.

2. Ignoring DeFi and on-chain income

If you only use exchange CSV exports, you're missing DeFi swaps, liquidity pool activity, governance token receipts, staking distributed off-platform, and most NFT marketplace activity. The 1099-DA (when applicable) doesn't capture this either.

3. Forgetting to answer the digital asset question

Answering "No" when you had any qualifying activity is perjury. The IRS specifically flags this question for enforcement.

4. Not tracking cost basis through the years

If you bought crypto in 2017 and sold in 2024, you need 2017 acquisition records. The exchange you bought on may not exist anymore. Reconstructing basis after the fact is expensive and sometimes impossible.

5. Pooling basis across wallets after 2025

Under the new wallet-by-wallet rule, basis must be tracked separately for each wallet. Continuing to use universal pooling after the transition date is no longer permitted.

When to hire a crypto tax professional

DIY crypto tax software is fine for simple situations – a Coinbase account, modest activity, no staking, no DeFi, no NFTs. The case for professional help gets stronger as complexity grows.

Signals that a professional is warranted:

• Multiple exchanges and self-custody wallets, especially across multiple chains
• Active DeFi participation (LP positions, yield farming, governance token receipts)
• Substantial NFT activity, especially in projects that might qualify as collectibles
• Staking, particularly liquid staking or re-staking through protocols like EigenLayer
• A material liquidity event (token unlock, large position exit, business sale)
• Prior years where crypto wasn't reported correctly, or any IRS contact about crypto
• A 1099-DA where the gross proceeds don't reconcile to your records
• Business activity involving crypto (accepting crypto payments, paying contributors in tokens, holding crypto on a balance sheet)

A qualified preparer – an IRS Enrolled Agent, CPA, or tax attorney with crypto experience – can spot positions you wouldn't think to take, document treatment that holds up on examination, and reconcile activity that automated tools mishandle.

CryptoAxis specializes in exactly this work. We prepare full U.S. individual and business returns coordinated with on-chain activity, and every engagement is led directly by Joelle Azwat, an IRS Enrolled Agent with a CPA background in public accounting and prior experience at PwC and TRES Finance.
