Can the IRS See Your Crypto Wallet?
Can the IRS see your crypto wallet? In most cases, yes. The IRS can’t log in to your wallet directly, but it can obtain your identity and transaction records from exchanges and combine them with public blockchain data to trace funds into self-custody wallets. Starting with the 2025 tax year, U.S. crypto brokers must also report users’ transactions directly to the IRS on the new Form 1099-DA.
How Does the IRS Get Information on Crypto Transactions?
The first channel is broker reporting. Exchanges and other brokers issue Form 1099-DA for transactions starting in 2025. Forms sent in early 2026 report only gross proceeds from sales or exchanges; for transactions from 2026 onward, brokers must report cost basis as well. The IRS automatically matches this data against taxpayers’ returns, and mismatches can trigger a notice.
The second channel is court-approved summonses. The IRS has used John Doe summonses to require platforms such as Coinbase, Kraken, and Circle to hand over records on groups of unnamed users. The Coinbase case covered about 14,000 accounts, and the Kraken case targeted users who transacted $20,000 or more between 2017 and 2020. In 2025, the U.S. Supreme Court declined to hear a privacy challenge to the Coinbase summons, so this approach remains in force.
The third channel is taxpayers’ own returns. The first page of Form 1040 asks whether you received, sold, or exchanged digital assets during the year, and answering truthfully is the taxpayer’s obligation.
Can the IRS See Self-Custody Wallets?
No intermediary reports on your behalf for a self-custody wallet, but that doesn’t make it invisible. Every transaction on a public blockchain is public, so as long as funds have passed through an exchange that knows your identity, the IRS can start from the exchange’s withdrawal address and use blockchain analytics tools to trace them to your self-custody address. In the Kraken summons case, the IRS combined exchange data with publicly available blockchain information.
Decentralized platforms are currently outside the scope of 1099-DA reporting, since Congress repealed the broker reporting rule for DeFi front ends in April 2025. But tax obligations haven’t changed: sales, swaps, and income from self-custody wallets or DeFi still have to be reported by the taxpayer.

What Does This Mean for Institutions?
Exchanges and payment companies operating in the U.S. that qualify as brokers must issue 1099-DAs to their users. That means accurately recording every transaction for every user, with its time and U.S. dollar value, and tracking cost basis from 2026 onward.
For funds and businesses that hold crypto themselves, the focus is on records. Since January 1, 2025, U.S. taxpayers must calculate cost basis wallet by wallet rather than pooling holdings across all wallets and exchanges. The more wallets an institution runs, the more it needs a wallet system that can export transaction records, approval records, and operation logs in one place, so audits and tax filings are fully documented.

Conclusion
Can the IRS see your crypto wallet? Through exchanges’ 1099-DA reporting, court-approved summonses, and public blockchain data, the IRS can see most transactions, and self-custody wallets are not invisible. For institutions, keeping complete, exportable transaction records for each wallet is the foundation for meeting tax and audit requirements.
