How Do Crypto Brokers Decide Which Wallets Fall Under 1099-DA Rules?
New tax reporting forms for digital assets sound like they should apply the same way everywhere, but the actual coverage rules hinge on one narrow question: does the broker actually hold and control the wallet, or does the customer?
The short answer
A platform is generally required to issue Form 1099-DA for accounts where it acts as a broker with custody or control over the digital assets and the transactions running through them. Wallets the platform does not custody, such as a private, self-hosted wallet a user controls independently, generally fall outside that specific reporting obligation, because the broker has no visibility into what happens inside them.
What “custody” means in this context
Custody refers to who holds the private keys and controls the ability to move the assets. When a platform holds assets on a customer’s behalf inside a custodial account, it can see every deposit, trade, and withdrawal that happens through its own systems, which is what makes it possible to compile the transaction history a 1099-DA requires. A self-hosted wallet, by contrast, is controlled entirely by the person holding the keys, and no outside platform has a complete record of that wallet’s activity unless it interacts directly with the platform’s own systems.
Why self-custodied wallets are treated differently
Because a broker only sees transactions that pass through its own platform, it cannot reliably report on activity happening entirely off its systems, such as a transfer between two self-hosted wallets that never touches an exchange. Reporting obligations are built around what a broker can actually observe and verify. This is also why moving assets between wallets a person controls themselves isn’t automatically a reportable sale for tax purposes; ownership hasn’t changed hands, only the location of the assets has, similar in spirit to how transfers between your own wallets are treated for tax purposes.
When a wallet does become covered
Coverage can extend beyond a platform’s core trading accounts. If a platform offers a hosted wallet service, provides staking through custodial arrangements, or otherwise exercises meaningful control over a customer’s assets, those relationships can fall under broker reporting requirements even if they’re branded or presented differently than a standard trading account. The determining factor stays consistent: whether the platform has enough control and visibility to compile an accurate record, not what the product is called.
How this fits into the bigger tax-reporting picture
1099-DA reporting is one piece of a broader shift toward brokers reporting more detailed cost basis information to the IRS, following a phased rollout rather than a single cutover date. Because these rules are still relatively new and continue to be refined through additional guidance, the specific thresholds, timelines, and edge cases can shift. It’s worth checking current IRS guidance or a tax professional’s read on the rules for a specific situation rather than relying on last year’s understanding.
A practical way to think about it
- Custodial exchange account. Platform holds the keys and generally issues 1099-DA for covered transactions.
- Self-hosted wallet, no platform interaction. Platform has no visibility and generally doesn’t report on that wallet’s internal activity.
- Self-hosted wallet interacting with a broker. The specific transaction touching the broker’s systems, such as a deposit or withdrawal, can still generate a reportable event on the broker’s side.
None of this changes an individual’s own underlying tax obligations, which apply regardless of whether a form was issued. Reporting rules determine who tells the IRS what, not what actually has to be reported by the taxpayer.
The bottom line
Whether a wallet falls under 1099-DA rules comes down to custody and visibility, not the type of coin or the size of the account. Platforms report on what they can see and control; wallets outside that boundary carry the reporting responsibility back to the individual, which is one more reason accurate cost-basis recordkeeping matters regardless of which forms show up in a given year.
