2025 Cryptocurrency Tax Compliance: Form 1099-DA, Broker Reporting, and the Wash Sale Legislative Outlook

Cryptocurrency tax compliance has undergone its most consequential transformation since the IRS first classified digital assets as property in 2014. The Infrastructure Investment and Jobs Act of 2021 introduced sweeping new broker reporting requirements that take effect with tax year 2025, fundamentally changing IRS visibility into crypto activity. Combined with continued enforcement actions, ongoing wash sale legislation, and DeFi reporting proposals, the era of unreported crypto activity is closing rapidly.

Form 1099-DA: The New Crypto Information Return

Beginning with tax year 2025 (returns filed in early 2026), U.S. cryptocurrency "brokers" must issue Form 1099-DA (Digital Asset Transactions) reporting customer dispositions to the IRS:

Who Is a "Broker"?

The IRS definition is broad and includes:

• Centralized exchanges (Coinbase, Kraken, Gemini, Binance.US, etc.).

• Crypto payment processors handling customer transactions.

• Hosted wallet providers facilitating dispositions.

• Crypto-friendly brokers offering trading services.

The DeFi reporting requirements were initially proposed but face implementation challenges and ongoing legislative debate. Whether decentralized exchanges, smart contract protocols, and self-custody wallet providers will ultimately be subject to broker reporting remains uncertain.

What Will Be Reported

For each reportable disposition:

• Gross proceeds.

• Date acquired and date sold.

• Cost basis (where available).

• Type and quantity of digital asset.

• Whether the gain/loss is short-term or long-term.

The basis reporting is phased in — initially limited to certain "covered securities" with full basis reporting expanding over time.

The IRS Matching Implications

With 1099-DA forms flowing to the IRS, taxpayers can no longer "forget" to report crypto activity from major exchanges. The IRS will perform information matching against tax returns, generating CP2000 notices for unreported income or basis discrepancies.

The Form 1040 Digital Asset Question

Since 2019, the federal individual tax return has included a question about digital asset activity. The 2024-2025 question is broad:

• Receive crypto as payment, reward, or compensation?

• Sell, exchange, or dispose of crypto?

• Receive crypto from staking, mining, airdrops, or hard forks?

• Receive crypto from a fork?

The question is signed under penalties of perjury. Answering "no" while crypto activity occurred constitutes potential tax fraud — a key consideration as 1099-DA matching makes unreported activity easier to detect.

Pending Wash Sale Legislation

The wash sale rule under §1091 currently does NOT apply to cryptocurrency because crypto is property (not a security). This allows crypto investors to:

• Sell crypto at a loss.

• Immediately rebuy the same crypto.

• Realize the loss without 30-day waiting period.

Multiple legislative proposals would extend the wash sale rule to digital assets:

• Build Back Better Act (2021): Included wash sale extension to crypto. Bill not enacted.

• Subsequent proposals: Various bills have proposed similar extensions.

• Treasury reports: Have repeatedly recommended extending wash sale to crypto.

Whether and when this change is enacted remains uncertain. For 2025, crypto wash sale harvesting remains permitted — making this potentially the last year for the strategy.

Cost Basis Tracking Challenges

For active traders, basis tracking remains the largest practical compliance challenge:

• Cross-exchange transfers require manual basis tracking.

• DeFi protocols (liquidity pools, yield farming, lending) generate complex transactions.

• Bridging across blockchains creates accounting questions.

• Wrapped tokens raise questions about whether wrapping triggers a disposition.

• Defunct exchanges may have lost transaction records, requiring reconstruction.

Crypto tax software (Koinly, CoinTracker, TokenTax, ZenLedger, Crypto.com Tax) automates much of this — but accurate reporting still requires careful review and reconciliation.

The Specific Identification Method

The IRS allows two basis methods for crypto:

• FIFO (First In, First Out): Default method — earliest-acquired units are deemed sold first.

• Specific Identification: Taxpayer chooses which specific lots to dispose of.

Specific identification requires meeting strict documentation requirements: at the time of sale, the taxpayer must identify the specific lot being sold by acquisition date, acquisition cost, and other identifying details.

For active traders with significant unrealized gains and losses across positions, specific identification can substantially reduce tax liability by selecting high-basis lots for sale.

Staking, Mining, and Airdrop Income

Staking Rewards

The IRS position: staking rewards are ordinary income at fair market value when the taxpayer obtains control over the rewards. Reported on Schedule 1 line 8 as "other income" (or Schedule C if mining/staking is a business).

The 2023 Jarrett v. United States case suggested staking rewards may not be income until disposed of, but the case was dismissed before final resolution. Conservative reporting follows the IRS position.

Mining Income

Crypto mining income is treated based on the scope of the activity:

• Hobby mining: Income on Schedule 1; expenses limited.

• Business mining: Income on Schedule C; expenses fully deductible; subject to self-employment tax.

For business miners, deductible expenses include electricity, equipment depreciation, internet, hosting fees, and mining pool fees.

Airdrops and Hard Forks

Airdrop income is recognized at fair market value when the taxpayer obtains "dominion and control" over the new tokens. Hard fork tokens are similarly recognized when control is established.

NFT Tax Treatment

NFTs (non-fungible tokens) follow standard property treatment with some unique considerations:

• Purchases with crypto trigger capital gain/loss on the crypto used to pay.

• Sales generate capital gain/loss based on holding period.

• The IRS issued guidance suggesting some NFTs may be "collectibles" subject to the higher 28% long-term capital gains rate.

• Royalty income is generally ordinary income to the original creator.

DeFi Taxation Complexity

Decentralized finance protocols create some of the most complex tax situations:

• Liquidity pool deposits: Often treated as a deposit (not a taxable disposition), but specific protocol mechanics matter.

• Yield farming rewards: Ordinary income at fair market value when received.

• Lending interest: Ordinary income.

• Wrapped tokens: Treatment unsettled — many practitioners treat as non-taxable conversion, but conservative reporting may treat as a disposition.

• Bridging across blockchains: Treatment generally similar to wrapping.

• Flash loans: Generally non-taxable due to atomic execution within a single transaction.

Foreign Crypto Account Reporting

Crypto held on foreign exchanges may trigger:

• FBAR (FinCEN Form 114): Treasury issued guidance in 2020 indicating crypto would be added to FBAR reporting, but final rules have not been issued. Conservative reporting includes foreign crypto holdings if total foreign accounts exceed $10,000.

• Form 8938 (FATCA): May apply to specified foreign financial assets above thresholds.

• Form 5471: May apply if crypto is held through foreign corporations.

IRS Enforcement Actions

The IRS has dramatically increased crypto enforcement:

• John Doe summonses against major exchanges (Coinbase, Kraken, Circle).

• Operation Hidden Treasure targeting crypto tax evasion.

• CP2000 matching notices for crypto income discrepancies.

• Letter campaigns (Letter 6173, 6174, 6174-A) warning taxpayers of potential reporting obligations.

• Criminal prosecutions for willful tax evasion involving crypto.

Voluntary Disclosure for Past Non-Compliance

Taxpayers with unreported crypto activity have several options:

• Quiet disclosure: Filing amended returns to correct prior years (highest risk if IRS finds the activity first).

• IRS Voluntary Disclosure Practice: Formal program for taxpayers with willful non-compliance — provides protection from criminal prosecution but requires payment of taxes, interest, and penalties.

• Streamlined Filing Compliance Procedures: Available for non-willful non-compliance, particularly for foreign account issues.

The right path depends on the facts. Engaging a CPA or tax attorney experienced in crypto compliance is essential before voluntary disclosure.

Common Mistakes

• Answering "No" to the digital asset question on Form 1040 when crypto activity occurred.

• Failing to recognize crypto-to-crypto trades as taxable events.

• Inaccurate basis tracking for legacy holdings or transactions across multiple exchanges.

• Missing staking and mining rewards as ordinary income.

• Treating wrapping or bridging as non-taxable without supporting documentation.

• Failing to file FBAR for foreign exchange holdings.

• Not maintaining transaction logs from defunct exchanges.

• Missing the 1099-DA matching implications for 2025+ activity.

Bottom Line

Cryptocurrency tax compliance has fundamentally changed for tax year 2025. With Form 1099-DA broker reporting taking effect, the IRS will have direct visibility into customer activity at major exchanges — making unreported activity dramatically easier to detect. Combined with continued enforcement actions and pending wash sale legislation, crypto investors must treat tax compliance as a year-round priority. Working with a CPA experienced in digital asset taxation is essential for accurate reporting, optimal tax outcomes, and audit defense.
