Crypto Tax Guide 2026: 1099-DA, Basis & Reporting

For U.S. federal tax purposes, digital assets are generally treated as property. Selling crypto for dollars, exchanging one digital asset for another materially different digital asset, or spending crypto can create a gain or loss. Receiving digital assets from services, staking, mining, or certain other events can instead create ordinary income depending on the facts.

The biggest 2026 reporting change is Form 1099-DA. U.S. brokers began reporting gross proceeds for covered 2025 digital-asset dispositions, so many taxpayers are seeing Form 1099-DA for the first time while filing 2025 returns in 2026. Most 2025 statements do not include cost basis. For sales after 2025, basis reporting begins for certain covered digital assets, but taxpayers still need their own records.

This article covers U.S. federal individual tax reporting, not state, foreign, entity, estate, or personalized tax advice.

Key takeaways

A digital-asset sale, exchange, or purchase of goods/services can create a reportable disposition even if no dollars reach your bank account.
A transfer between wallets you own is generally not a taxable disposition, but crypto used to pay the transfer fee can itself be disposed of.
Form 1099-DA does not eliminate your responsibility to report transactions or maintain cost-basis records.
2025 Form 1099-DA statements generally focus on gross proceeds; basis reporting phases in for certain covered assets sold after 2025.
Cost-basis identification is now wallet/account sensitive, so old “one universal pool across every wallet” assumptions should not be used without checking the current IRS rules.

Tax rules are fact-specific and can change. Use current IRS forms and instructions for the tax year you are filing, and use a qualified tax professional for material or ambiguous transactions.

What changed for crypto taxes in 2026?

There are two different timelines that are easy to confuse.

When	What matters
2026 filing season	Taxpayers file 2025 federal returns. U.S. digital-asset brokers may furnish the new Form 1099-DA for reportable 2025 dispositions. Most 2025 forms do not include basis.
Transactions after December 31, 2025	Broker basis reporting begins for certain digital assets that qualify as covered securities under the current rules.
Your tax return	You remain responsible for reporting taxable digital-asset income, gains, and losses even if no Form 1099-DA arrives or a form lacks basis.

The IRS states that broker gross-proceeds reporting applies to transactions effected on or after January 1, 2025, while basis reporting applies to certain transactions effected on or after January 1, 2026.

That phase-in matters because a 2025 Form 1099-DA can show proceeds without telling you what you originally paid. A large proceeds number is therefore not the same thing as taxable gain.

Which crypto activities can create a taxable event?

For a person holding digital assets as capital assets, the common reporting patterns look like this:

Activity	Typical U.S. federal treatment	Main record to keep
Buy crypto with U.S. dollars and keep it	No gain/loss merely from the purchase	Acquisition date, units, price, transaction costs
Hold crypto without disposing of it	No gain/loss merely from holding	Wallet/account and basis records
Sell crypto for dollars	Capital gain/loss may be recognized	Basis, proceeds, transaction costs, sale date
Exchange BTC for ETH or another materially different digital asset	Disposition of the asset transferred; gain/loss may be recognized	Basis of disposed asset and value/cost details of exchange
Spend crypto on goods or services	Disposition of the crypto; gain/loss may be recognized	Basis and value of goods/services received
Transfer crypto between your own wallets/accounts	Generally no gain/loss on the transferred principal	Transfer records proving common ownership
Pay a transfer or transaction fee with crypto	Crypto used for the fee can itself be a disposition	Units used for fee, basis, fair market value
Receive crypto for services	Generally ordinary income at fair market value when received	Date/time, units, U.S.-dollar value, business/employment context
Receive proof-of-stake validation rewards	Current IRS guidance treats qualifying rewards as gross income when the taxpayer gains dominion and control	Date/time dominion and control begins, units, fair market value

This table is a starting framework, not a classification engine. DeFi transactions, derivatives, lending arrangements, wrapped assets, liquidity positions, gifts, charitable transfers, business inventory, and entity transactions can require different analysis.

The dedicated crypto airdrop guide explains claim and wallet-security mechanics. For taxes, do not assume every promotional token distribution is automatically treated the same way. IRS Revenue Ruling 2019-24 specifically addresses an airdrop of new cryptocurrency following a hard fork; other distributions can require fact-specific analysis.

How do you calculate a crypto capital gain or loss?

For a straightforward capital-asset disposition, the core concept is:

Gain or loss = Amount realized − Adjusted basis

The difficult part in crypto is usually not the subtraction. It is determining the correct units sold, basis, amount realized, and transaction-cost allocation.

Example: sale for dollars

Assume a taxpayer:

buys 0.5 BTC for $20,000;
pays $100 in qualifying transaction costs to acquire it;
later sells the 0.5 BTC for $30,000;
pays $120 in qualifying transaction costs to sell it.

A simplified illustration would begin with an acquisition basis of $20,100. The amount realized may be reduced by transaction costs allocable to the sale under the current digital-asset rules. The resulting difference is the capital gain or loss before considering other tax rules.

Do not automatically apply that same fee treatment to every crypto-to-crypto exchange. The IRS's updated digital-asset FAQs contain specific allocation rules for transaction costs in exchanges, including situations where units are withheld to pay fees.

Cost basis is now a wallet/account problem, not just a spreadsheet total

A common legacy approach was to treat every unit of the same token across every exchange and self-custody wallet as one universal tax-lot pool. Current IRS rules are more specific.

For digital-asset acquisitions and dispositions on or after January 1, 2025, basis identification is generally applied on a wallet-by-wallet or account-by-account basis under the updated rules and transition guidance.

Specific identification

For an unhosted wallet, the IRS allows specific identification if, no later than the date and time of the disposition, you identify the particular units in your books and records using sufficient identifiers and keep adequate records showing those units left the wallet.

For digital assets held with a custodial broker after 2025, specific identification generally must be communicated to the broker by the date and time of the transaction using identifiers the broker accepts, and you must maintain supporting records.

What happens if you do not specifically identify the units?

The current IRS default rules generally identify units by acquisition order—starting with the earliest-acquired units within the applicable wallet or custodial account—when valid specific identification is not made.

This is why a tax report that combines all BTC from every exchange and wallet into a single undifferentiated FIFO pool can be wrong under the current framework.

Keep at least:

asset type;
wallet or account;
acquisition date and time;
number of units acquired;
U.S.-dollar fair market value when acquired;
basis and qualifying transaction costs;
disposition date and time;
units disposed;
amount realized;
transaction IDs and transfer records where available;
the identification method or standing instruction used with the broker.

What Form 1099-DA tells you—and what it does not

Form 1099-DA reports digital-asset broker transactions. It is an information return, not a complete tax calculation.

For 2025 transactions reported in early 2026

The IRS warns that most statements for 2025 will not include basis. That means you may receive a gross-proceeds figure but still need to reconstruct the basis yourself before calculating gain or loss.

For sales after 2025

The 2026 Form 1099-DA instructions require basis reporting for digital assets that are covered securities. In simplified terms, covered status depends on how and when the asset was acquired and whether it remained in an account for which the broker provided custodial services.

Transferred-in assets and older holdings can be noncovered. A broker may therefore know the sale proceeds while not being required—or permitted—to report the basis you believe applies.

No 1099-DA does not mean no tax reporting

Foreign exchanges, self-custody transactions, decentralized protocols, peer-to-peer activity, and other situations may not produce the same broker form. The IRS nevertheless states that taxable income, gains, and losses must be reported regardless of whether an information return is received.

Where do crypto transactions go on a U.S. federal return?

The correct form depends on what happened.

Capital-asset sales and exchanges

For individuals, the IRS directs taxpayers to use the applicable Form 8949 and Schedule D rules for digital-asset capital transactions.

The IRS's current FAQ notes that Form 8949 may not be required for a transaction when a broker has provided Form 1099-DA containing both gross proceeds and basis information. Follow the instructions for the tax year you are actually filing rather than assuming every 1099-DA transaction is reported the same way.

Ordinary digital-asset income

Non-business ordinary income can flow to Form 1040 or Schedule 1 as applicable. Crypto received for independent-contractor services can instead involve Schedule C and self-employment rules. Employee wages paid in digital assets have their own wage-reporting treatment.

The digital-asset question

Taxpayers filing forms that contain the digital-asset question must answer it. Merely buying digital assets with real currency, holding them, or transferring assets between accounts you own can generally support a “No” answer when those are the only activities. Selling, exchanging, receiving certain rewards, or paying fees with digital assets can change the answer.

Use the IRS's current digital-asset questionnaire and instructions for the filing year rather than relying on an old screenshot or social-media checklist.

How are staking rewards and airdrops treated?

These terms are often grouped together online, but the IRS guidance is not identical for every distribution.

Proof-of-stake validation rewards

Revenue Ruling 2023-14 addresses a cash-method taxpayer receiving additional units as proof-of-stake validation rewards. The ruling says the fair market value is included in gross income when the taxpayer gains dominion and control over the reward units.

That income amount can then matter for the basis of the reward units when they are later disposed of.

Hard-fork airdrops

Revenue Ruling 2019-24 addresses a specific hard-fork scenario. A hard fork without receipt of new cryptocurrency does not, by itself under the ruling's facts, create gross income. If a hard fork is followed by an airdrop and the taxpayer receives new units over which they have dominion and control, the ruling concludes that gross income is recognized.

Do not stretch that ruling into “all airdrops are taxed identically.” Promotional distributions, rewards, rebates, compensation, gifts, protocol incentives, and other token receipts can involve different facts.

What records should a crypto trader keep?

The IRS says records must be sufficient to support positions taken on the federal return. For digital assets, a practical audit trail should connect each tax result back to the actual wallet, account, and transaction.

A useful reconciliation file contains:

Raw exchange exports — do not rely only on a summarized tax report.
Wallet addresses you own or control — so own-wallet transfers can be distinguished from dispositions.
Acquisition lots — date/time, units, basis, and source.
Disposition records — date/time, units, proceeds/value received, and transaction costs.
Transfer mapping — source wallet, destination wallet, transaction ID, and proof both accounts belong to you where relevant.
Income receipts — staking, services, rewards, mining, or other receipts with fair market value at the relevant recognition time.
Broker forms — preserve every Form 1099-DA and any corrected version.
Basis-identification instructions — preserve specific-ID or standing instructions communicated to a custodial broker.

A broker tax export can be a useful reconciliation input, but it should not be treated as proof that transfers, basis, and every DeFi transaction were classified correctly.

A practical crypto tax review workflow

Before filing, work through the records in this order:

1. Freeze the tax year

Separate transactions by the actual tax year. Do not mix 2025 transactions reported on a 2026 filing-season Form 1099-DA with 2026 transactions that will generally belong to the next filing cycle.

2. Reconcile every wallet and exchange

Confirm that transfers between accounts you own are matched rather than accidentally recorded as sales or income.

3. Separate receipts from dispositions

A receipt can create ordinary income; a later sale of the same units can create a second tax event based on the unit's basis and sale proceeds.

4. Resolve basis by wallet/account

Confirm which tax lot was actually sold under the current identification rules. Do not silently use a universal multi-wallet lot pool.

5. Compare your records with Form 1099-DA

Check proceeds, asset, transaction dates, covered/noncovered status, and basis if reported. If the form is wrong, IRS guidance says to contact the issuer and request a corrected form while keeping the correspondence.

6. Map each transaction to the current IRS form instructions

Use the current Form 8949, Schedule D, Schedule 1, Schedule C, or other applicable instructions. Do not assume the form used last year is automatically correct this year.

7. Escalate ambiguous transactions

Professional review becomes more important when the history includes DeFi liquidity positions, bridges, derivatives, business activity, gifts, inherited assets, bankrupt platforms, token vesting, foreign reporting, or incomplete basis records.

Frequently asked questions

Do I have to report crypto if I did not receive Form 1099-DA?

Yes. The IRS says taxpayers must report taxable digital-asset income, gains, and losses whether or not they receive Form 1099-DA or another information return. Your own transaction and basis records still matter.

Is swapping one cryptocurrency for another taxable in the United States?

Generally, yes when the digital assets exchanged are materially different. The IRS treats the exchange as a disposition of the transferred digital asset, so a capital gain or loss may have to be calculated using the asset's adjusted basis and the transaction's amount realized.

Is transferring crypto between my own wallets taxable?

Moving the same digital asset between wallets or accounts that you own or control is generally not a taxable disposition. However, if you pay a transfer fee using digital assets, the digital assets used to pay that fee can themselves create a reportable disposition.

Does Form 1099-DA include my crypto cost basis?

For 2025 transactions, most Form 1099-DA statements report gross proceeds without basis, so taxpayers must calculate basis from their records. For sales after 2025, brokers must report basis for certain covered digital assets, but transferred-in and other noncovered assets may still require taxpayer-maintained basis records.

Where are crypto capital gains reported on a U.S. federal tax return?

The IRS directs individuals to report digital-asset capital transactions using the applicable Form 8949 and Schedule D rules. Form 8949 may not be required for a transaction when a broker has provided Form 1099-DA with both gross proceeds and basis information, subject to the current form instructions.

Does ChartMini calculate crypto taxes or generate Form 8949?

No. ChartMini is a historical chart-replay tool. It does not import exchange or wallet transactions, track tax lots, calculate digital-asset basis, reconcile Form 1099-DA, or generate tax forms.
