Does Coinbase Report to the IRS? Yes. Here's Exactly What They Share.

If you've been assuming your Coinbase activity flies under the radar, that assumption is now officially expired. We know the IRS can track crypto, but as a Coinbase user, just exatly what does the IRS have on you?

What Tax Forms Does Coinbase Send to the IRS?

Depending on your activity, Coinbase may issue up to three forms to both you and the IRS. Let's work down the list from most common to most obscure.

Coinbase Form 1099-DA

‍Form 1099-DA is the form most if not all Coinbase users will receive. Introduced for the 2025 tax year, this form covers broker-tracked digital asset disposals including sales and exchanges of crypto on the platform. Reporting scope can vary based on asset type, transaction classification, and what Coinbase can actually see. For 2025, Coinbase reports gross proceeds only, which is the total value received from disposals before accounting for cost basis or fees. Starting with the 2026 tax year, cost basis reporting is added, bringing crypto broker reporting closer to how traditional securities have been reported, though the rules are not identical.

Coinbase Form 1099-MISC

Form 1099-MISC applies if you earned $600 or more in Coinbase-paid income during the year, including staking rewards, referral bonuses, and similar payments.

Coinbase Form 1099-B

Form 1099-B applies only if you traded through Coinbase's Derivatives Exchange. Most retail users never interact with this venue and will not receive this form.

Does Coinbase Hand Over Customer Information to the IRS?

Coinbase does not automatically send the IRS your full raw transaction history as part of routine reporting. However, the IRS can and does obtain additional data through legal process, including John Doe summonses, which have been used against major exchanges before. This is not routine, but it is real, and it has happened.

Beyond legal process, Form 1099-DA now creates a direct data pipeline between Coinbase and the IRS. Significant discrepancies between what Coinbase reports and what you file can increase your risk of receiving an IRS notice, including a CP2000. Not every mismatch triggers one, but the IRS does match reported figures against filed returns, and unexplained gaps draw scrutiny.

Why Are My 1099 Forms From Coinbase Inaccurate?

This is the question I hear most often right now, and the answer comes down to one thing: data visibility.

Coinbase can only report what it knows. If you bought Ethereum on Kraken in 2019, moved it to a cold wallet, then transferred it to Coinbase and sold it in 2025, Coinbase has no record of your original purchase. In that scenario, your 1099-DA is likely to show cost basis as "not reported" rather than a confirmed figure. The burden of establishing your actual cost basis then falls entirely on you.

For traders who have moved assets across wallets and exchanges over the years, that is not a minor inconvenience. It is a material tax risk. And it is happening right now to traders across the country.

What Should I Do If My Coinbase 1099-DA Looks Wrong?

First, download your 1099-DA from Coinbase Taxes as soon as it is available. For the 2025 tax year, Coinbase is required to provide it no later than March 17, 2026.

Second, do not rely on it as your only record. Reconcile it against your actual transaction history across every wallet and exchange you have used. If cost basis shows as not reported, and for many active traders it will, you need your own documentation to establish it correctly.

Third, get your cost basis methodology locked down. The IRS requires consistent application of your chosen accounting method, whether that is FIFO, HIFO, or specific identification. While it is possible to change methods under certain conditions, doing so requires care and documentation. Once you have set your historical method within Coinbase's platform, their system does not allow changes, so confirm carefully before locking it in.
