How to find and read your Coinbase tax documents
A plain walkthrough of the Coinbase tax center, what each document tells the IRS, and where the numbers go wrong.
You log into Coinbase in February, click around for a form that says 1099, and either find one number that looks way too high or nothing at all. Both reactions are normal, and neither means you did anything wrong. Coinbase hands you a few different documents. They say different things, and only one of them is built for actually filing. Here's where each one lives and what it's telling you.
Where the tax center actually is
On the website, open your profile menu in the top right and look for Taxes, or go straight to coinbase.com/taxes. In the app it sits under your profile settings. Coinbase calls this whole area Coinbase Taxes, and it holds three separate things: a gain/loss report, any 1099 forms Coinbase filed for you, and your raw transaction history as a CSV.
Those three are not interchangeable. People get burned by grabbing the first PDF they see and typing its number onto their return. Slow down for a second and figure out which document you're actually looking at.
Gain/loss report vs. 1099 vs. raw CSV
The gain/loss report is the one you file from. It takes each time you sold or swapped a coin, subtracts what you paid, and shows the profit or loss on that specific disposal. That profit-or-loss figure is what flows onto Form 8949 and then Schedule D. If you had a handful of trades and everything you touched was bought and sold on Coinbase, this report is usually close to right.
The 1099 is a different animal. For the 2025 tax year, Coinbase issues the new Form 1099-DA if you sold or exchanged crypto, and a copy goes to the IRS. Here's the catch worth sitting with. For 2025, that form reports gross proceeds only. Cost basis reporting phases in for 2026 activity. So the 1099-DA can show, say, $40,000 of proceeds even though you spent $37,000 buying the coins and your real gain was $3,000. The IRS sees the big number. Your job is to fill in what you paid, so you're taxed on the gain and not the whole sale.
Earn $600 or more in crypto income, staking rewards or referral bonuses and the like, and you'll also get a Form 1099-MISC. That income is taxed as ordinary income at its dollar value the day you received it, separate from any gain when you later sell.
The raw CSV is every transaction you made, unsummarized. It's the messiest file and the most honest one. When the gain/loss report looks off, the CSV is where a pro or a piece of software goes to rebuild the numbers from scratch.
One change for 2025: Coinbase no longer generates a completed Form 8949 inside its retail tax center. You get the gain/loss data, but the actual 8949 comes out of your tax software or preparer.
Why transfers in and out break the basis
We'll match you with a vetted crypto-tax pro who reconciles your transfers, tracks down the basis Coinbase couldn't see, and files it right. Free intro call, no obligation.

Coinbase can only track what it can see. If you bought one Ethereum on Coinbase for $2,000 and later sold it there, Coinbase knows both ends and the math is clean. But say you bought that Ethereum somewhere else, or in your own wallet, then sent it to Coinbase and sold it. Coinbase watches the coin land, but it has no idea you paid $2,000 for it. On its records, that coin showed up from nowhere.
When you sell it, Coinbase either reports a cost basis of zero or flags the basis as unknown. A zero basis means the entire sale price looks like profit. Sell at $4,000 and your $2,000 gain gets reported as a $4,000 gain, and you'd overpay unless you correct it with your own purchase records.
It runs the other way too. Send coins out of Coinbase to a hardware wallet or another exchange, and Coinbase stops being able to follow them. Sell later somewhere else and that other platform hits the same blind spot Coinbase had. The purchase price has to travel with you, and no exchange does that for you.
So before you trust any number, ask yourself two things:
- Did every coin I sold get bought on this same account? If yes, the report is probably solid.
- Did I move coins in from an outside wallet or another exchange at any point? If yes, assume the basis is missing and needs fixing.
Handing it off to software or a pro
If you used one exchange and never moved coins around, you can usually take the gain/loss report, enter the totals into consumer tax software or hand the PDF to your preparer, and be done. Keep the 1099-DA next to it so the proceeds match what the IRS received.
If you used multiple exchanges or wallets, don't try to stitch it together by hand. Export the raw CSV from every place you traded, Coinbase included, and load them into crypto tax software or give them to someone who does this for a living. The software matches each sale to the right purchase across platforms and rebuilds the basis the exchanges couldn't see. That's the whole job: reconnecting coins to what you actually paid for them.
A few practical notes while you gather documents. Losses aren't just paperwork you file, they're money back. Capital losses offset your gains dollar for dollar, and if losses run past your gains you can knock up to $3,000 off ordinary income, then carry the rest forward to future years. The wash-sale rule that stops stock investors from claiming a loss and rebuying right away does not currently apply to crypto, though Congress has floated changing that, so don't assume it holds forever. And the digital-asset question at the top of your Form 1040 gets a yes if you sold, swapped, or received crypto this year. Selling and answering no is the kind of mismatch that draws attention.
Grab all three Coinbase documents in one sitting, check whether any coins came in from outside, and within ten minutes you'll know whether this is a type-it-in job or one worth handing to a professional.
