What Is the Difference Between Form 1099-DA and Form 1099-B?
Anyone who has sold stock is probably familiar with receiving a 1099-B at tax time. A newer form, the 1099-DA, was built specifically for digital assets, and the two forms, while related, aren’t interchangeable.
The short answer
Form 1099-B has long been used to report proceeds from broker transactions, primarily stocks and other traditional securities. Form 1099-DA is a newer form built specifically for digital asset brokers to report cryptocurrency sales, and it’s designed to capture information relevant to crypto transactions, such as wallet and transfer details, that 1099-B was never built to handle.
Why a separate form was created
Cryptocurrency’s tax treatment has generally followed property rules rather than the rules that apply to traditional securities, but broker reporting requirements had not caught up until more recently. Form 1099-B was designed decades ago around the mechanics of a stock or bond trade executed through a traditional brokerage. Digital asset transactions often involve details a stock trade doesn’t, such as multiple wallets, transfers between platforms, and cost basis information that can be harder to track, which is part of why tracking crypto cost basis is so difficult in the first place. Form 1099-DA was introduced to address those gaps directly.
What each form generally reports
- 1099-B reports securities transactions. It typically includes proceeds from a sale, and depending on the broker’s records, cost basis and gain or loss information for stocks, bonds, and similar assets.
- 1099-DA reports digital asset transactions. It’s built to capture proceeds from crypto sales along with details specific to digital assets, including information about the wallets or accounts involved.
- Basis reporting differs between them. Because digital asset basis can be tracked differently depending on the accounting method used, the basis details captured on a 1099-DA may look different from what’s typically shown on a 1099-B for a stock trade.
What this means for someone filing taxes
Receiving a 1099-DA doesn’t change the fundamental tax treatment of crypto transactions; gains and losses are still generally calculated and reported the same way. But it does mean more of the underlying transaction detail is now reported directly to tax authorities rather than relying solely on the taxpayer’s own records. This shift also has implications for quarterly estimated tax obligations, since more consistent third-party reporting can make discrepancies between what’s reported and what’s filed easier to notice.
Why this area keeps changing
Reporting requirements for digital assets have been evolving over the past several years, and the specifics of what brokers must report, and when, continue to be refined. Because rules in this area change and depend on individual circumstances, including which platforms are treated as brokers, it’s worth verifying the current requirements each tax season rather than assuming last year’s process still applies.
What to weigh
The core difference between the two forms comes down to what they were built for: 1099-B for traditional securities, 1099-DA for digital assets with all their added complexity. Understanding which form applies to a given transaction, and what basis information it captures, makes it easier to reconcile personal records with what’s ultimately reported to tax authorities.
