Explore community questions and practical answers about 1099 da.
With Form 1099-DA fully starting for 2026 transactions (including cost basis reporting by brokers), how should individual taxpayers prepare? Will exchanges accurately report cost basis for transferred assets, and what should I do if their numbers don't match my own records? Any tips for avoiding penalties?
Hi all, I'm UK-based but hold and trade crypto on US platforms (e.g., Coinbase). For transactions in 2025, brokers are now issuing the new Form 1099-DA reporting gross proceeds (and eventually cost basis in future years). Has anyone received or seen sample 1099-DAs yet? How does this interact with HMRC reporting – will the data get shared automatically, or do I need to manually align my UK capital gains calc with whatever the US form says? Worried about mismatches causing issues. Any advice on reconciling the two? Appreciate it!
