Form 1099-DA Reporting in 2026: Who Must Issue It, What It Shows, and What the IRS Sees Beyond It

The short answer

Form 1099-DA applies to digital asset sales a broker effects for customers on or after January 1, 2025. Under IRC Section 6045 and the final regulations, a broker is any person who, in the ordinary course of business, stands ready to effect sales of digital assets for others and takes possession of the assets: custodial trading platforms, hosted wallet providers, digital asset kiosks and certain processors of digital asset payments. Real estate reporting persons that see digital assets change hands at a closing are brokers for closings on or after January 1, 2026. Businesses that only supply hardware or software for self-custody, and proof-of-work or proof-of-stake validators, are outside the definition. The separate rule that would have pulled in DeFi front ends (T.D. 10021) was repealed by Congress under H.J.Res.25, signed April 10, 2025, and cannot be reissued in substantially similar form without new legislation.

For 2025 sales the form reports gross proceeds, dates and units; basis reporting was voluntary. Brokers had to furnish those statements by February 17, 2026 and e-file them by March 31, 2026, with penalty relief for good-faith errors under Notice 2024-56 and transitional backup withholding relief under Notice 2025-33. For sales from January 1, 2026, brokers must also report adjusted basis on covered digital assets, meaning assets acquired after 2025 in the same account, so the statements customers receive in early 2027 will show gain or loss. The IRS instructions for Form 1099-DA carry the field-by-field detail.

The IRS matches every 1099-DA against the recipient's return automatically, so businesses and their customers need to reconcile before filing, not after a notice arrives. This guide covers who is a broker, the phase-in timeline, and how to build compliant reporting systems.

What the IRS sees beyond your 1099-DA

A 1099-DA is a floor, not a ceiling. Chainalysis estimated in August 2026 that on-chain potentially taxable crypto activity reached more than $457 billion in 2025, roughly $112.6 billion of it in the United States, and that only about 14% of that activity sits within the practical reach of broker-style frameworks such as CARF. The other 86% is decentralized exchange trading, peer-to-peer transfers, self-custody movements, staking and lending income, and crypto payments. Forbes summarized the implication on August 27, 2026 under the headline "The IRS Can See More Crypto Than Your 1099-DA Shows": tax authorities are moving to wallet-based enforcement, using blockchain analytics to follow assets from a centralized exchange into private wallets and onward. Source: Chainalysis, On-Chain Taxable Activity.

Two practical consequences follow. First, the absence of a 1099-DA does not mean the IRS cannot see the activity, and the IRS states plainly that digital asset transactions must be reported whether or not a form arrives. Second, a 2025 form that shows proceeds without basis will be matched as if the entire proceeds were gain unless the taxpayer supplies basis from their own records. The businesses I work with keep a wallet-level ledger that reconciles every exchange statement to on-chain movements, which is the only way to defend both the form the IRS holds and the activity it does not.

Understanding IRC Section 6045(c) and the Expanded Definition of Digital Asset Brokers

The launch of Form 1099-DA on January 1, 2025, represents the most significant expansion of tax reporting requirements since the creation of the modern tax system. For crypto businesses, this new form fundamentally changes how transactions are reported to the IRS and creates unprecedented transparency in the digital asset ecosystem.

Historical Context - Why Form 1099-DA Was Necessary

Before 2025, cryptocurrency transactions existed in a reporting vacuum that created significant challenges for both taxpayers and the IRS. Most crypto exchanges provided no tax forms, some platforms used Form 1099-MISC for large transactions, traditional brokers used Form 1099-B only for securities, and DeFi platforms provided no reporting at all.

The lack of systematic reporting created an estimated $50 billion annual "tax gap" in unreported crypto income, according to IRS studies. This gap undermined tax compliance and created unfair advantages for non-compliant taxpayers. Congress addressed this gap through the Infrastructure Investment and Jobs Act, which expanded the definition of "broker" to include digital asset service providers and mandated standardized reporting through Form 1099-DA.

IRC Section 6045(c) - Legal Foundation of the New Requirements

IRC Section 6045(c) now defines a broker as "any person who (for consideration) is responsible for regularly providing any service effectuating transfers of digital assets on behalf of another person."

Key legal elements include:

• "For consideration" requirement covering fees, commissions, or spread compensation, subscription-based services, revenue sharing arrangements, and does not require direct customer charges as advertising revenue may qualify.
• "Regularly providing" standard encompasses consistent, ongoing service provision, not limited to daily operations, includes seasonal or periodic services, and excludes one-time or isolated transactions.
• "Service effectuating transfers" scope includes direct execution of buy/sell orders, custodial services for customer assets, wallet hosting and management services, and payment processing using digital assets.

Entities Required to Issue Form 1099-DA

Traditional Crypto Exchanges

Hosted Wallet Providers

Digital Asset Payment Processors

Reporting Requirements

Traditional crypto exchanges must report gross proceeds from all sales, date and nature of each transaction, customer identification information, and cost basis beginning in 2026.

Hosted wallet providers are distinguished from self-custody solutions where only custodial wallet providers are subject to reporting requirements. Self-custody wallets where users control private keys are not covered.

Digital asset payment processors must report payments processed for merchants, consumer-to-business transactions, B2B payment facilitation, and international payment processing.

Custodial staking services include exchange-based staking programs, institutional staking providers, pooled staking services, and delegated proof-of-stake validators with custodial features. Non-custodial DeFi protocols and validators are currently exempt from reporting requirements, though this may change in future regulations.

Treasury Regulation § 1.6045-1 Implementation Details

Form 1099-DA content requirements include customer name, address, and taxpayer identification number, description of digital asset transferred, date of each transaction, gross proceeds from sales, and basis information beginning 2026.

Reporting Thresholds and Requirements

Expanded Broker Definition - Who's Covered and Who's Not

Clearly Covered Entities

All centralized cryptocurrency exchanges that hold customer funds are unambiguously covered under the new definition, including both spot trading platforms and derivatives exchanges. Any entity that holds digital assets on behalf of customers while providing transaction services falls under the broker definition. Companies that facilitate digital asset payments between parties are covered when they maintain custody during the transaction process.

Gray Area Entities

DeFi protocol developers face regulatory uncertainty. Potentially covered protocols include those with administrative controls, upgradeable smart contracts with centralized governance, and protocols collecting fees through centralized mechanisms. Likely exempt protocols include fully decentralized protocols with immutable contracts, open-source software without centralized control, and protocols operating entirely through smart contracts.

Digital asset definitions include NFTs, creating reporting requirements for custodial NFT platforms like OpenSea and Rarible with custody features, gaming platforms with in-game asset trading, and metaverse platforms with asset exchanges.

Mining and staking pools require complex analysis for different pool structures. Custodial pools that hold customer assets are likely covered, while non-custodial pools with self-custody arrangements may be exempt.

Timeline and Implementation Phases

• 2025 sales (forms issued in early 2026): Gross proceeds, dates and units reported; basis reporting voluntary. Statements furnished to customers by February 17, 2026, e-filed with the IRS by March 31, 2026. Penalty relief for good-faith reporting under Notice 2024-56; wrapping, staking, lending and certain other transactions temporarily exempt under Notice 2024-57.
• 2026 sales (forms issued in early 2027): Basis reporting mandatory for covered digital assets acquired after 2025. Aggregate reporting rules apply to qualifying stablecoins and specified NFTs. Real estate reporting persons report the fair market value of digital assets used in closings on or after January 1, 2026.
• What is not coming: The DeFi front-end broker rule was repealed under the Congressional Review Act in April 2025. There is no quarterly or real-time 1099-DA reporting. The remaining expansion is international: CARF exchanges of information begin with 2026 data in participating jurisdictions, which matters for any broker with non-US customers.

Compliance Strategies for Crypto Businesses

For Entities Subject to Reporting Requirements

Technology infrastructure development requires system capabilities including customer transaction database with historical data, automated Form 1099-DA generation and filing, integration with IRS filing systems, and backup withholding calculation and processing.

Third-party software solutions include TaxBit Professional for crypto tax reporting, Lukka Enterprise for institutional compliance, Chainalysis for transaction monitoring and compliance, and custom solutions for large-scale operations.

Operational compliance procedures require customer onboarding enhancements including enhanced KYC procedures with tax focus, Form W-9/W-8 collection and validation, backup withholding notification procedures, and annual customer information updates. Transaction monitoring systems need real-time transaction classification, suspicious activity identification and reporting, cross-platform transaction coordination, and audit trail maintenance and documentation.

Risk Management and Penalty Avoidance

Civil penalties include $280 per missing or incorrect form (2025 amounts), up to $3.4 million annual maximum per entity, enhanced penalties for intentional disregard, and customer lawsuit exposure for incorrect reporting. Criminal penalties include willful failure to file that may result in criminal prosecution, money laundering violations for inadequate reporting, and tax evasion charges for systematic non-compliance.

Best practices for penalty avoidance include over-reporting rather than under-reporting when uncertain, professional review of all 1099-DA forms before filing, regular legal and tax advisor consultation, and industry best practice benchmarking and adoption.

International Implications and CARF Coordination

Crypto businesses operating internationally face complex reporting obligations. U.S. reporting requirements include Form 1099-DA for U.S. customers regardless of business location, FBAR reporting for foreign crypto accounts, and Form 8938 reporting for specified foreign financial assets. Foreign reporting requirements include CARF implementation in participating countries, local digital asset reporting requirements, and tax treaty coordination and information sharing.

Strategic considerations for global operations include separate legal entities for different jurisdictions, transfer pricing coordination for inter-company transactions, and professional service provider coordination across borders.

What to expect next

Domestic expansion has stalled: the DeFi broker rule was repealed in April 2025 and a substantially similar rule would need new legislation. The live developments are basis reporting on 2026 sales, the aggregate reporting rules for stablecoins and specified NFTs, and CARF, under which participating jurisdictions begin exchanging 2026 crypto account data in 2027. The United States is not yet a CARF participant, but US brokers with foreign customers, and US taxpayers with accounts at foreign platforms, will feel it through the partner side of those exchanges.

Conclusion

Form 1099-DA brings digital asset transactions into the same reporting framework as traditional securities, creating unprecedented transparency but also compliance burdens. Crypto businesses must run reporting systems that already work for 2025 forms, prepare for mandatory basis reporting on 2026 sales, and expect CARF information exchanges to widen what foreign tax authorities share with the IRS. Professional compliance infrastructure is no longer optional: it's the price of admission to legitimate crypto markets.
