Does Cash App report to the IRS?
Cash App is reported to have switched from Form 1099-B to Form 1099-DA for bitcoin sales beginning with the 2025 tax year, reporting gross proceeds with cost basis added for bitcoin acquired on or after January 1, 2026, and to issue Form 1099-MISC for $600 or more in bitcoin rewards; Cash App's own bitcoin-tax help page could not be rendered for direct verification, though parent company Block's Square unit publishes its own Form 1099-DA page confirming the same 2025 start and that 1099-DA replaces 1099-B. Separately, Cash App for Business accounts receive Form 1099-K for payment volume, which is unrelated to crypto.
reported by a third party, not the platform itselfWhat the rule actually says
Under the final digital-asset broker regulations, custodial brokers (centralized exchanges, hosted wallet providers, some payment processors and kiosks) must report gross proceeds from digital-asset sales on the new Form 1099-DA for transactions effected on or after January 1, 2025; those first forms were furnished to customers and filed with the IRS in early 2026. Decentralized/non-custodial brokers that never take possession of the assets are not covered by this filing requirement.
Cost-basis reporting is phased in one year later: brokers must report basis only for 'covered' digital assets, meaning assets acquired for cash or property on or after January 1, 2026 in an account with that same broker and held there until the broker effects the disposition. For the 2025 tax year, IRS copies of Form 1099-DA carry gross proceeds only (several brokers still showed basis on the customer copy, marked as not reported to the IRS).
A digital asset transferred into a broker from another platform or from a self-custody wallet is expressly a NONCOVERED security under the Form 1099-DA instructions, and the broker is not required to report its cost basis. The broker checks the noncovered box (box 9) and may leave the basis, acquisition-date and gain/loss boxes blank without penalty. In practice this means a 1099-DA from the platform where you sold will usually show proceeds with missing or platform-guessed basis whenever the coins were bought somewhere else and moved in - the taxpayer, not the broker, has to supply the true basis.
The number no form contains
A broker reports what it can see: the proceeds of a sale it executed. It cannot report what you paid on a different platform, in a wallet, or years earlier — and under the final regulations it does not have to. Coins that arrived from somewhere else are noncovered: the basis box can be blank, and no penalty follows. The IRS matching computer then treats a blank basis as zero, so the entire sale price reads as profit. That gap is not an error by the exchange; it is the design, and it is yours to close with evidence.
What to do about it
Reconstruct the basis before a notice arrives, not after. A free scan reads the export you already have, rebuilds lots wallet by wallet, cites the evidence beside every figure, and shows you the difference between what a blank-basis form implies and what you actually owe. No account, no card, three minutes.
