Crypto tax reporting 2026: Form 1099-DA, wash sale pending, and cost basis methods

Crypto tax reporting in the United States has been materially reorganized over the past 18 months. Three regulatory anchors set the framework for tax year 2026 filings: (1) Form 1099-DA broker reporting, with gross proceeds reporting active since January 1, 2025 and cost basis reporting mandatory for transactions on or after January 1, 2026; (2) Revenue Procedure 2024-28, which eliminated the universal cost basis pooling method and mandated per-wallet tracking starting January 1, 2025; and (3) the sustained classification of cryptocurrency as property (not stock or securities) under IRS Notice 2014-21, which keeps the wash sale rule of IRC Section 1091 from applying to digital assets despite multiple legislative proposals to the contrary.

Form 1099-DA implementation follows a phased timeline. Tax year 2025 — brokers report gross proceeds only, with Notice 2024-56 providing good-faith relief for failure-to-file and failure-to-furnish penalties during the transition. Tax year 2026 forward — brokers must report both gross proceeds AND cost basis for covered securities. A digital asset becomes a "covered security" when acquired on a centralized exchange on or after January 1, 2026 and held continuously within the same broker account through disposition. Assets acquired before January 1, 2026 or transferred between brokers retain non-covered status — taxpayer must supply basis from records.

The broker definition is narrower than originally proposed. Final regulations apply to brokers that take possession of digital assets being sold for customers — operators of custodial digital asset trading platforms, certain digital asset hosted wallet providers, digital asset kiosks, and certain processors of digital asset payments (PDAPs). Centralized exchanges like Coinbase, Binance.US, Kraken, Gemini, and Crypto.com are clearly within scope. Custodial wallet providers and payment processors like Coinbase Commerce and BitPay are within scope. Bitcoin ATMs and kiosks are within scope. Decentralized exchanges (Uniswap, Jupiter, SushiSwap), self-custody wallets (MetaMask, Ledger, Trezor), and node operators are NOT within scope — the Senate voted in 2025 to revoke decentralized platforms from the broker definition, removing the most contested portion of the original regulation. The $600 aggregate proceeds threshold per customer per broker determines whether a Form 1099-DA must be issued.

The cost basis reporting change is the most material taxpayer impact for 2026 filings. For 2025, taxpayers must supply basis from their own records when reporting Form 8949 transactions, since brokers report proceeds only. For 2026 onward, broker-reported basis will appear on Form 1099-DA for covered securities, simplifying reconciliation but creating new exposure: if your records and broker basis disagree, the IRS now has a third-party reported figure to compare against. Reconciliation discipline becomes mandatory.

The crypto tax framework affects different investor archetypes differently. Below are three representative profiles showing how the 2026 changes intersect with realistic trading patterns. Each profile uses approximate FMV inputs reflective of Q1-Q2 2026 markets and applies the per-wallet cost basis tracking requirement, the wash sale exemption, and the Form 1099-DA reporting transition.

Profile A: High-volume trader, mixed crypto + stocks portfolio. Sarah, age 38, trades actively on Coinbase, Kraken, and a self-custody MetaMask wallet for DeFi. 2026 activity includes 450 crypto trades across centralized exchanges, 80 DEX swaps on Uniswap and SushiSwap, and $200,000 in stock activity through a traditional brokerage. Sarah receives Form 1099-DA from Coinbase and Kraken (with gross proceeds and basis on covered securities acquired after January 1, 2026) but receives nothing from MetaMask DEX activity — she bears full tracking responsibility for the 80 DEX swaps. Her total gross proceeds across crypto brokers exceeds $1.8M, with realized gains of $42,000 after accounting for $18,000 in tax-loss harvesting executed in December 2026 using the wash sale exemption (sold ETH at loss December 28, repurchased December 29, full $11,000 loss deductible). Per-wallet cost basis tracking required across her three wallets — software automation via CoinTracker handles the per-wallet allocation post-Revenue Procedure 2024-28. Reports Form 8949 with Box A and Box D for covered securities, Box C and Box F for self-custody DEX activity.

Profile B: HODLer, long-term Bitcoin and Ethereum positions. Michael, age 45, holds 1.5 BTC and 12 ETH accumulated since 2020 across Coinbase and a Ledger hardware wallet. 2026 activity: sells 0.25 BTC at $98,000 ($24,500 proceeds) and 2 ETH at $4,200 ($8,400 proceeds) — both held more than 12 months, qualifying as long-term capital gains. Coinbase issues Form 1099-DA showing gross proceeds and basis (assets transferred from Ledger to Coinbase Coinbase prior to January 1, 2026 are NOT covered — Coinbase reports as "basis not reported to IRS"). Michael computes basis from his original 2020 acquisition records: 0.25 BTC at $9,500 = $2,375 basis; 2 ETH at $400 = $800 basis. Long-term capital gain = ($24,500 + $8,400) − ($2,375 + $800) = $29,725. Subject to 15% long-term capital gains rate (Michael total income places him in 15% LTCG bracket) = $4,459 tax. No NIIT applies (under $200,000 single income threshold). Reports Form 8949 Box D with basis adjustment code indicating basis from records.

Profile C: DeFi participant with staking and liquidity provision. Lisa, age 32, runs a 5 ETH validator on Ethereum proof-of-stake (running her own node, not staking pool) and provides liquidity on Uniswap V3. 2026 activity: earned 0.18 ETH in validator staking rewards across 12 monthly receipts with FMV at receipt of $720 (total $720 ordinary income reported on Schedule 1 Line 8z); earned $3,200 in trading fees from Uniswap LP positions (ordinary income at receipt); rebalanced LP positions twice, triggering disposal events for the underlying token pairs (computed as capital gains based on the FMV of LP token at exit minus the FMV at entry). Lisa receives ZERO Forms 1099-DA — all activity is self-custody (node operator + DEX). Full tracking burden on Lisa. Total ordinary income from DeFi $3,920; total capital gains from LP rebalancing $1,800 (short-term, taxed at ordinary income rates since held less than 12 months); plus year-end tax-loss harvesting of $4,500 from a failed altcoin position (deductible against capital gains via wash sale exemption sustained).

These profiles illustrate the operational asymmetry of the 2026 framework: high-volume traders on custodial platforms benefit from automated Form 1099-DA reconciliation but bear per-wallet tracking burden across multiple custodial platforms; HODLers face minimal complexity but lose covered-security status when transferring between brokers; DeFi participants retain maximum protocol flexibility but absorb full tax reporting and basis-tracking responsibility. The wash sale exemption favors all three, but the tax-loss harvesting strategy delivers the highest dollar value for active traders with realized gains to offset.

The final broker definition is narrower than the proposed 2023 regulations. Within scope — operators of custodial digital asset trading platforms that take possession of customer assets, hosted wallet providers, digital asset kiosks (Bitcoin ATMs), and digital asset payment processors. Centralized exchanges (Coinbase, Binance.US, Kraken, Gemini, Crypto.com, Bitstamp) fall squarely within scope. NFT marketplaces meeting the broker definition (OpenSea, Magic Eden, Blur) must also issue Form 1099-DA starting with 2025 transactions, subject to the same $600 aggregate proceeds threshold.

Outside scope — decentralized exchanges (Uniswap, SushiSwap, Jupiter, PancakeSwap), self-custody wallets (MetaMask, Trust Wallet, Phantom, Ledger, Trezor), and node operators. The Senate voted in 2025 to revoke decentralized platforms from the broker definition, removing the most legally contested portion of the original Treasury proposal. This means DEX trades, peer-to-peer transfers, and self-custody activity require taxpayer-supplied basis on Form 8949 with no third-party reporting reconciliation.

The $600 aggregate proceeds threshold per customer per broker is the issuance trigger — below that amount, no Form 1099-DA is required to be filed with the IRS or furnished to the customer. Above the threshold, the broker must report. Note that the $600 threshold is per broker, not aggregated across brokers — a taxpayer with $400 proceeds at Coinbase and $400 proceeds at Kraken receives no Form 1099-DA from either, but the $800 combined is still reportable income.

Notice 2024-56 transition relief applies for tax year 2025 only. Brokers making a good-faith effort to file timely and accurately are not subject to failure-to-file or failure-to-furnish penalties during 2025. For 2026 onward, full penalty exposure applies for incorrect or late filings. Brokers are also required to perform backup withholding (24%) on certain reportable transactions when the customer fails to provide a Taxpayer Identification Number — additional transition relief was extended for backup withholding during the 2025 transition.

Practical implication for the 2026 filer: collect all Forms 1099-DA from every custodial broker and reconcile against your per-wallet records before filing. Where the broker basis is incomplete or incorrect (common during transition due to transfers from other platforms or pre-2026 acquisitions), report the corrected basis on Form 8949 with an adjustment code in column (f). For decentralized exchange activity, prepare a separate Form 8949 batch in Box C (short-term, not reported) or Box F (long-term, not reported) with full basis documentation.

Revenue Procedure 2024-28, issued in July 2024 with effective date January 1, 2025, made per-wallet cost basis tracking mandatory and ELIMINATED the prior universal cost basis pooling method. This is the most consequential operational change in crypto tax compliance since the 2014 Notice classifying crypto as property. Taxpayers who used universal cost basis tracking through tax year 2024 had to perform a one-time allocation of remaining unused basis to specific wallets by the safe harbor deadline — earlier of the first disposition with unused basis in 2025 or the filing of the 2025 Form 1040 (extensions included). That safe harbor closed with the 2024 filing window. Going forward, no universal pooling is permitted.

Two allocation methods were specified in the Revenue Procedure for the universal-to-per-wallet transition: Specific Unit Allocation (taxpayer assigns each remaining basis unit to a specific wallet based on actual or chosen identification) and Global Allocation (taxpayer applies a uniform allocation rule across all wallets, typically pro-rata based on holdings). Taxpayers who failed to complete allocation by the safe harbor deadline are technically out of compliance — IRS guidance on remediation paths for missed safe harbor remains limited as of Q1-Q2 2026.

Per-wallet tracking applies to all five cost basis methods: FIFO (First-In, First-Out, the default), LIFO (Last-In, First-Out), HIFO (Highest-In, First-Out), WAC (Weighted Average Cost), and Specific Identification. Each wallet maintains its own basis pool; election of method applies at the wallet level, not the account level. A taxpayer can elect FIFO on one wallet and HIFO on another — the elections must be documented contemporaneously with each disposition.

Specific Identification requires contemporaneous election. The taxpayer must identify the exact units sold (by acquisition date, basis, and time) at the moment of disposition. Retroactive election after the fact is not permitted per longstanding IRS guidance for stock and securities (applied analogously to crypto). For high-volume traders, software automation handles the per-wallet contemporaneous election — CoinTracker, Koinly, CoinLedger, ZenLedger, and CoinTracking all support per-wallet method election post-Revenue Procedure 2024-28. Verify your software has been updated.

Practical implication: if you previously relied on universal cost basis pooling (combining basis across all wallets owned to produce a single average cost), your 2025 and 2026 tax positions are materially different. Per-wallet tracking typically produces higher reportable gains for taxpayers who concentrated low-basis acquisitions in one wallet and high-basis acquisitions in another — the prior pooling smoothed the difference; per-wallet tracking surfaces it. Run scenario analysis on your portfolio to understand the 2025 tax year impact before filing.

The wash sale rule under IRC Section 1091 prohibits claiming a tax loss on the sale of stock or securities when the same or substantially identical position is repurchased within 30 days before or after the disposition. The rule applies to stock, bonds, and securities — but NOT to cryptocurrency, which IRS Notice 2014-21 classifies as property. As of Q1-Q2 2026, this exemption remains intact.

Multiple legislative proposals have attempted to extend wash sale to digital assets since 2021. The Build Back Better Act of 2021 included a wash sale extension provision that was dropped from the final reconciliation package. The Inflation Reduction Act of 2022 included an early draft of wash sale extension that was removed before enactment. The One Big Beautiful Bill Act (OBBBA), enacted July 2025, did NOT include wash sale extension to digital assets despite intense lobbying from both sides. The GENIUS Act and the CLARITY Bill (both 2025 digital asset framework legislation) similarly did not modify Section 1091. As of Q1-Q2 2026, no enacted legislation extends wash sale to crypto.

Tax-loss harvesting strategy: sell crypto positions held at unrealized loss before year-end to recognize the loss for tax purposes, then immediately repurchase the same crypto to maintain market exposure. Because the wash sale rule does not apply, the loss is fully deductible against other capital gains (and up to $3,000 against ordinary income if losses exceed gains). The "same-day repurchase" strategy is unique to crypto — no equivalent is available for stocks without violating Section 1091.

Practical execution: identify positions with unrealized losses 30+ days before year-end to allow execution flexibility. Use Specific Identification per-wallet to select the highest-cost-basis lots within each wallet for the loss harvest (maximizes loss size). Execute the sale and the repurchase as separate transactions through the same custodial broker or self-custody wallet — same-day execution is permitted, but settle with at least minimal time spacing (intra-day) for clean records. Document the harvested loss with screenshots of the trade confirmations and the basis reconciliation. Report the loss on Form 8949 with no adjustment code (no wash sale disallowance applies).

Strategic caveat: treat the exemption as potentially temporary. Every new tax bill introduces additional probability that wash sale will eventually extend to crypto. Industry analysts widely expect extension within the next 2-4 years even if no specific timeline is mandatory. For 2026 tax planning specifically, the exemption is sustained — execute year-end harvesting with confidence. For multi-year strategic positioning, build flexibility into the assumption that the exemption may not be available beyond 2027 or 2028.

DeFi staking and lending rewards are ordinary income at the moment of dominion and control over the new tokens, valued at fair market value (FMV) at receipt. The FMV at receipt establishes the cost basis for those tokens. Subsequent disposition triggers capital gain or loss based on disposition price minus established basis. Report ordinary crypto income on Schedule 1 (Form 1040), Line 8z (Other Income). This framework applies uniformly across staking pools, validator node operation, lending protocols (Aave, Compound), and yield farming positions. The IRS has not issued DeFi-specific protocol-by-protocol guidance, but the dominion-and-control test applies consistently.

Liquidity provision on Uniswap, SushiSwap, and similar AMM protocols requires more granular analysis. Depositing tokens into a liquidity pool exchanges your underlying tokens for LP (liquidity provider) tokens. Whether this is a taxable disposition is contested — conservative position: treat the deposit as a disposition of underlying tokens at FMV and recognize capital gain/loss at deposit. Aggressive position: treat the deposit as a non-taxable exchange (analogous to a partnership contribution). The IRS has not issued definitive guidance. Most tax practitioners recommend the conservative position for risk minimization. Withdrawing tokens from the pool similarly triggers a disposition of LP tokens for underlying tokens, with capital gain/loss recognized based on the FMV difference.

NFTs are subject to look-through analysis under IRS Notice 2023-27. If the NFT represents ownership of an underlying collectible (art, antiques, gems, metals, stamps, coins, alcoholic beverages — the Section 408(m) list), the NFT is taxed as a collectible. Long-term holdings (more than 12 months) are taxed at the collectibles rate capped at 28% — the cap means actual rate equals the taxpayer ordinary income bracket, capped at 28%. Short-term holdings (12 months or less) are taxed at ordinary income rates regardless of collectible classification. If the NFT represents an asset NOT on the Section 408(m) list (virtual land in a metaverse, utility tokens, membership rights, profile picture NFTs), it is treated as standard property — long-term gains taxed at 0%/15%/20% plus NIIT 3.8% if applicable.

The IRS look-through analysis has not been fully tested across all NFT types. NBA Top Shot trading card NFTs, art NFTs, and PFP collections like CryptoPunks may eventually be classified as collectibles — most practitioners apply the conservative position (collectibles treatment) for these categories pending further IRS guidance. Virtual land NFTs (Decentraland, The Sandbox parcels) are clearly property under current guidance. Utility tokens granting access rights or membership (BAYC apes treated as access tokens to certain events) operate in the gray zone.

Mining rewards are ordinary income at receipt, valued at FMV when the taxpayer gains dominion and control. The FMV establishes basis. Subsequent disposition triggers capital gain/loss. Hobby mining vs business mining classification affects deductibility of expenses (electricity, equipment depreciation) — business mining qualifies for Schedule C treatment with full expense deduction and self-employment tax exposure; hobby mining reports income on Schedule 1 with no expense deduction.

Airdrops and hard forks are ordinary income at receipt per IRS Revenue Ruling 2019-24. If the taxpayer has dominion and control over the new tokens (received via airdrop or as a result of a hard fork), the FMV at receipt is ordinary income reported on Schedule 1. If the taxpayer does not have dominion and control (tokens are locked, not yet credited to a wallet the taxpayer controls), no income is recognized until the dominion-and-control test is met. Receipt of new tokens via a hard fork without taxpayer action (passive distribution to existing wallet) still triggers income when the taxpayer can access them — the test is dominion-and-control, not active claim.

Brazilian residents in the US face dual-jurisdiction reporting obligations under both US tax law and Brazilian Lei 14.754/2023. The interaction is operationally complex because each jurisdiction defines residency, source income, and reporting thresholds differently.

US side — FATCA (Form 8938). Specified foreign financial assets must be reported on Form 8938 when total value exceeds the threshold. For taxpayers living in the US, the threshold is $50,000 on the last day of the year or $75,000 at any point during the year (single filer); $100,000 / $150,000 (married filing jointly). For taxpayers living abroad, thresholds increase to $200,000 / $300,000 (single) and $400,000 / $600,000 (joint). IRS guidance on whether crypto held in foreign exchanges or self-custody wallets automatically triggers Form 8938 reporting remains evolving — many cross-border tax practitioners recommend conservative reporting of crypto on Form 8938 even in the absence of definitive guidance, particularly when crypto is held on a foreign exchange (Binance international, Bitfinex, etc.).

US side — FBAR (FinCEN Form 114). Foreign financial accounts must be reported on FBAR when aggregate value of all foreign accounts exceeds $10,000 at any time during the calendar year. The FBAR threshold is meaningfully lower than Form 8938. Crypto held on a foreign exchange may trigger FBAR — FinCEN guidance has been less clear than IRS guidance on this specific point. Conservative reporting recommended.

Brazilian side — Lei 14.754/2023. Effective for tax years 2024 onward, Lei 14.754/2023 imposes a uniform 15% income tax on offshore financial income earned by Brazilian tax residents, regardless of distribution. Controlled foreign entities (offshores) with own income below 60% or located in tax havens are subject to automatic taxation on profits at the entity level — the Brazilian tax resident pays 15% on the entity profits even without distribution. Trusts and investment funds receive similar treatment with structural rules adapted to each vehicle type. The optional asset revaluation election (8% rate on the difference between historical acquisition cost and December 31, 2023 market value) was available during the 2024 transition window.

Treaty interaction. The US-Brazil tax treaty of 1967 is limited in scope — it does NOT cover dual taxation on capital gains, dividend income, or most investment income types. There is no broad treaty preventing dual taxation. Brazilian residents in the US typically rely on Foreign Tax Credit (FTC) on the US side for taxes paid to Brazil, and on the Brazilian side rely on credit for US taxes paid (limited by Brazilian law). The result is partial relief, not full exemption. Foreign Earned Income Exclusion (FEIE) is available for US taxpayers living abroad meeting the physical presence or bona fide residence tests but does NOT apply to investment income (including crypto).

For Brazilian residents in the US with material crypto holdings (>$50,000 single thresholds, $100,000 joint), professional cross-border specialist engagement is operationally mandatory. The combination of FATCA + FBAR + Lei 14.754/2023 with no full-scope treaty creates compliance complexity that exceeds typical CPA bandwidth. Specialist firms with US-Brazil tax practice (Trench Rossi Watanabe, Pinheiro Neto with US affiliate, KPMG cross-border) are the practical compliance path.

Step 1 — Inventory all wallets and exchanges. List every centralized exchange account (Coinbase, Binance.US, Kraken, etc.), every self-custody wallet (MetaMask, Ledger, Trezor, etc.), and every DEX position. For each, document the acquisition history including dates, amounts, and basis. This is the foundation for per-wallet cost basis tracking.

Step 2 — Verify Form 1099-DA receipt and reconcile to records. For each centralized exchange and custodial wallet provider, confirm receipt of Form 1099-DA for tax year 2025 (gross proceeds only) and prepare to receive enhanced 2026 Form 1099-DA (with basis for covered securities). Reconcile broker-reported amounts against your records — discrepancies are common during transition.

Step 3 — Confirm per-wallet cost basis tracking compliance. Verify that your software (CoinTracker, Koinly, CoinLedger, ZenLedger) has been updated for per-wallet tracking post-Revenue Procedure 2024-28. If you previously used universal pooling, confirm the one-time allocation was completed by the safe harbor deadline. If not, consult a crypto tax specialist for remediation.

Step 4 — Elect cost basis method per wallet contemporaneously. Default is FIFO. Specific ID requires contemporaneous election at disposition. For high-volume traders, configure software to apply Specific ID or HIFO automatically. For HODLers with simple wallets, FIFO default typically suffices.

Step 5 — Execute year-end tax-loss harvesting strategy. Identify positions with unrealized losses 30+ days before year-end. Use the wash sale exemption to sell-and-immediately-repurchase. Document loss harvest with trade confirmations and basis reconciliation. Apply losses against capital gains first, then up to $3,000 against ordinary income.

Step 6 — Classify DeFi, NFT, mining, airdrops correctly on Schedule 1 vs Schedule D. Ordinary income (staking, lending, mining, airdrops, hard forks) on Schedule 1 Line 8z. Capital gains on Form 8949 + Schedule D. NFT classification per look-through analysis — conservative position is collectibles treatment for art and PFP NFTs.

Step 7 — For Brazilian residents in US, engage cross-border specialist. FATCA + FBAR + Lei 14.754/2023 + 1967 treaty interaction exceeds typical CPA bandwidth. Specialist firms with US-Brazil practice are operationally mandatory above $50,000 single threshold.

For taxpayers with simple profiles (single exchange, HODLer, no DeFi, no NFT, no cross-border), self-preparation via TurboTax or H&R Block Premium can suffice. For high-volume traders, DeFi participants, NFT collectors, miners, or cross-border filers, professional preparation by a crypto-specialized CPA delivers material value through error reduction and strategy optimization. The 2026 compliance environment is meaningfully more complex than 2024 — the per-wallet mandate, Form 1099-DA reconciliation, and continuing scrutiny on DeFi/NFT classification all increase the cost of self-preparation error.
