Does Coinbase report to the IRS?

If you've bought or sold crypto on Coinbase, you've probably wondered how much of it the IRS can see. The short answer is yes, and more than it used to. Coinbase sends tax forms to you and to the IRS, it has turned over customer records under a court order, and starting with your 2025 activity a new form covers a lot more than the old ones did. Here's what actually gets reported, and what stays your job to report yourself.

So does Coinbase report to the IRS?

Yes. Coinbase is a US company, and US companies that pay you income or handle your trades file information returns. Copies go to the IRS with your name and taxpayer ID on them. So by the time you sit down to do your return, the IRS may already have a number tied to your Social Security number. If what you file doesn't line up with what Coinbase reported, the mismatch is easy for their systems to flag, and that's often what triggers one of those automated CP2000 notices in the mail.

What Coinbase has sent in the past

For years the main form Coinbase issued was a 1099-MISC. If you earned $600 or more from staking rewards, referral bonuses, or similar payouts in a year, you'd get one, and so would the IRS. That form reports earned income, valued in dollars at the time you received it. It's ordinary income, taxed at your normal rate.

The gap was everything else. A 1099-MISC never covered your actual trades. So if you sold a few thousand dollars of Ethereum at a gain, or swapped one token for another, none of that showed up on the form, even though a sale or swap is exactly the kind of event you owe tax on. Plenty of people saw no form for their trading and assumed there was nothing to report. That assumption is where a lot of back-tax problems start.

What changes with Form 1099-DA

Form 1099-DA is the new digital-asset form built to close that gap. Coinbase and other custodial exchanges have to issue it starting with the 2025 tax year, and you should get your 2025 form by around mid-March 2026. It reports your disposals, meaning the sales and swaps the old form ignored.

One catch for this first year. The 2025 form shows gross proceeds only, not cost basis. Gross proceeds is the total dollar amount you sold or swapped, with no subtraction for what you originally paid. So if you bought Bitcoin for $8,000 and later sold it for $9,000, the form may show $9,000, not the $1,000 gain you'd actually be taxed on. Seeing that big number without context scares people. It isn't your tax bill. You still subtract your basis to get the real gain or loss. Cost basis reporting starts with 2026 activity, so the forms you get in early 2027 should carry both figures.

One more thing worth knowing: the separate rule that would have forced DeFi platforms to file broker forms was repealed in 2025. So 1099-DA reporting comes from custodial exchanges like Coinbase, not from your self-custody DeFi activity, at least for now.

The court order, and what the IRS can already see

Forms are only part of it. Back in 2016 the IRS went to federal court with what's called a John Doe summons, asking Coinbase to hand over records for large groups of users it couldn't name individually. A judge narrowed the request. Coinbase ended up producing account records for thousands of customers who had moved significant amounts through the platform, and none of those users got a form. The IRS asked, a court agreed, and the data went over.

Activity on public blockchains like Bitcoin and Ethereum is also visible to anyone, including the analytics firms the IRS pays. Moving coins off Coinbase to a private wallet doesn't erase the trail. It just moves it onto a ledger the whole world can read.

A missing 1099 was never a green light. It just means the paperwork didn't reach you, not that the tax went away.

Why you report even with no form

US tax law treats crypto as property, and the duty to report is yours regardless of what paperwork arrives. The IRS puts a digital-asset question right at the top of your Form 1040, and answering it honestly is on you. It comes down to two cases, selling and earning:

• When you sell crypto for dollars, swap one token for another, or buy a coffee with crypto, that's a disposal. You have a capital gain or loss equal to the value at disposal minus what you paid. Held a year or less, the gain is taxed at your ordinary rate; held longer than a year, it gets the lower long-term rates.
• When you earn crypto, from staking, a reward, or getting paid in it, that's ordinary income at the dollar value the day you received it. That same value becomes your cost basis if you sell it later.

Losses are the part people leave on the table. Capital losses offset your capital gains first, and if your losses run larger, you can deduct up to $3,000 against ordinary income for the year and carry the rest forward. A token you bought at $5,000 and sold at $1,500 is a real $3,500 loss you can use, but only if you report the sale.

A note on the wash-sale rule, since it comes up a lot: the rule that blocks stock investors from selling at a loss and rebuying within 30 days does not currently apply to crypto. That can work in your favor for now. Congress has floated proposals to extend it to digital assets, so it's worth watching rather than treating as permanent.

Whatever your forms say this spring, the reconciliation still happens on your end. You take the proceeds Coinbase reported, match them against your real purchase records, and land on the actual gain or loss for each disposal on Form 8949, which flows to Schedule D. Do that, and a scary-looking gross-proceeds number turns back into the modest gain, or the deductible loss, it always was.
