Reporting begins with gross proceeds from custodial platforms and phases in basis reporting afterwards, with transitional relief for certain transfers. The effect is to bring crypto closer to the equities model of form-1099-b.
The hard part is basis across wallets. Assets moved between exchanges and self-custody arrive without history, so the broker may report proceeds against unknown basis, and reconciling that falls to you. Per-wallet rather than universal basis tracking is the direction of travel.
Crypto is treated as property for US federal tax, so each disposal is a taxable event, including swapping one token for another and spending it. The wash-sale-rule as written applies to securities, and its application to digital assets has been repeatedly proposed for change.
General information for the United States, not tax advice. Rules change frequently here and depend on your circumstances; take professional advice.
