‘The exchange didn't send me a tax form’ is no longer a defensible position in either the US or the EU — and it is becoming less defensible everywhere else too, as three separate reporting frameworks converge on the same conclusion: every disposal is a taxable event, and tax authorities are increasingly seeing your data directly rather than relying on you to self-report.
CARF: 76 Jurisdictions and Counting
The OECD's Crypto-Asset Reporting Framework is the most significant shift in global crypto tax transparency to date. As of 2026, 76 jurisdictions have committed to implementing it, requiring exchanges and wallet providers to automatically share transaction data — account identification, wallet addresses, transaction amounts, and gains, losses, and income from disposals and rewards — with tax authorities in participating countries. The rollout is staged: 46 jurisdictions begin exchanging data in 2027, 29 more join in 2028, and the United States itself begins CARF participation in 2029. If you hold crypto on an exchange in a participating jurisdiction, your data may now reach your home country's tax authority regardless of where the exchange is based — the assumption that offshore exchanges sit beyond reach no longer holds.
DAC8: Already Live in the EU
The EU's DAC8 directive entered into force on January 1, 2026, requiring crypto service providers operating in the EU to collect and report customer transaction data to national tax authorities, who then exchange it across member states. First reports are due September 30, 2027, covering 2026 transactions, and notably, DAC8 explicitly includes NFTs as crypto assets for reporting purposes — not just tokens and coins.
Form 1099-DA: The US Broker-Reporting Equivalent
The IRS's Form 1099-DA is the crypto equivalent of the 1099-B already used for stocks and bonds, requiring brokers to report digital asset proceeds. The phase-in matters: 2025 tax year covers gross proceeds only, with no cost basis required yet. From 2026 onward, full cost basis reporting applies. By 2027, brokers report complete lot-level detail. Once your broker is reporting your own disposals with cost basis data directly to the IRS, any mismatch between what they report and what you file becomes a detectable, automated discrepancy — not something that quietly goes unnoticed.
What This Actually Changes About Your Compliance Strategy
Together, these three frameworks mean exchanges are now reporting entities that will share your data with your tax authority, cost basis mismatches are newly detectable rather than invisible, and your own records need to function as a defense — if audited, what you kept needs to match what the exchange already reported on your behalf. Confirm your exchanges have your correct tax residency and TIN information on file now, and check that whatever crypto tax software you use is configured to ingest 1099-DA data once it becomes available.
