Key Takeaways
- • The IRS Form 1099-DA, launched for tax year 2025, marks the first-ever federally mandated crypto transaction reporting requirement, but exchanges are transmitting gross sales data without accompanying cost-basis information—creating a fundamental gap in tax liability calculation.
- • Investors will receive 1099-DA forms in January and February 2026 disclosing digital asset transactions, yet the IRS will lack the cost-basis data necessary to independently verify tax obligations, forcing taxpayers to reconcile incomplete exchange records with their actual acquisition costs.
- • Assets transferred into centralized exchanges (including Coinbase) will not display cost-basis information on IRS filings even when taxpayers self-report it, compounding compliance complexity and creating potential audit exposure across millions of cryptocurrency holders.
- • Industry experts warn of widespread confusion and administrative burden, with tax attorneys describing the rollout as inadequately publicized and fundamentally incomplete, potentially triggering IRS enforcement action against taxpayers attempting to reconcile mismatched transaction records.
- • The reporting requirement originates from the 2021 infrastructure law, but exchanges and the IRS have failed to establish adequate data standards or raise stakeholder awareness ahead of the January filing deadline.
Summary
The IRS's rollout of Form 1099-DA for cryptocurrency tax reporting is creating significant compliance friction as exchanges and brokers begin transmitting transaction data without the cost-basis information required to calculate actual tax liability. The new standardized form, mandated by provisions in the 2021 infrastructure law, represents the first federal effort to improve digital asset reporting by establishing uniform disclosure obligations across exchanges, brokers, and payment platforms. However, the implementation reveals a structural deficiency: while the 1099-DA captures gross sales proceeds from certain digital asset transactions, it omits the acquisition cost data—or cost basis—that taxpayers and the IRS need to determine taxable gains or losses.
This gap creates a problematic asymmetry. The IRS will receive matching transaction records from exchanges disclosing what investors sold and for how much, but will lack the foundational cost-basis figures necessary to independently verify whether reported tax liability is accurate. Consequently, taxpayers must themselves reconcile the IRS-filed 1099-DA data against their personal acquisition records, a process complicated by the fact that assets transferred into centralized exchanges will not display cost-basis information on forms sent to the IRS—even if the taxpayer previously self-reported that data to the exchange.
The compliance burden is expected to intensify dramatically when cost-basis reporting requirements formally begin in 2026. Tax attorneys and accountants warn that stakeholder awareness remains critically low despite the imminent January and February 2026 filing deadlines when millions of 1099-DA forms will arrive in investor mailboxes. Shehan Chandrasekera, chief of tax strategy for CoinTracker, noted that "only a small number" of affected parties understand the incoming forms, creating potential chaos across the industry. Chicago tax attorney Andrew Gordon described the situation bluntly: "This is going to be a mess. The IRS is going to receive an incomplete picture, forcing the taxpayer to clear up that incomplete picture."
Additional complexity stems from potential divergence between federal and state tax rules, with some jurisdictions imposing separate disclosure and filing obligations independent of the federal 1099-DA framework. Taxpayers unable to reconstruct complete exchange histories—due to platform shutdowns, lost credentials, or years of unreconciled self-custody transactions—face particular audit exposure as the IRS begins matching reported proceeds against filed tax returns.
