3 easy tax-planning tools for cryptocurrency investors
You don't need a spreadsheet habit to stay ready for tax season. Three kinds of tools do most of the record-keeping for you, and they matter more now that exchanges report your sales straight to the IRS.
The IRS has treated cryptocurrency as property since 2014, which means most sales, swaps, and spends create a capital gain or loss you have to report. What changed recently is who else sees those trades. For the 2025 tax year, US exchanges began sending the IRS a form that reports what you sold, so the agency now holds its own record of your activity. Keeping your own records in order is how you make sure the two line up.
None of this takes a finance background. Three kinds of tools handle most of the work, and you can set them up in an afternoon. Here is what each one does and where it stops being enough.
Crypto tax software that imports your whole history
The most useful tool is software that connects to your exchanges and wallets and pulls in every transaction. Koinly, CoinTracker, CoinLedger, and TokenTax all work this way. You link an account with a read-only API key or upload a CSV export, and the software rebuilds your buys, sells, swaps, and transfers, then fills in Form 8949 and the totals that carry to Schedule D.
Two habits decide whether the output is right. Connect every account, including old exchanges you stopped using and any self-custody wallets, because a missing source shows up as a coin that arrived from nowhere and inflates your gain. Then review the transactions the software could not classify on its own, such as staking rewards, an airdrop, or a bridge between chains. The import gets you most of the way; the review is the part worth your time.
Exchange tax reports and the new 1099-DA
Every major US exchange gives you a year-end gain and loss report plus a full transaction export in your account settings. Download both for each year you traded. The gain and loss report is a fast check against your software, and the raw export is your backup if you ever need to rebuild your history from scratch.
Starting with the 2025 tax year, custodial exchanges also file Form 1099-DA with the IRS and send you a copy. For 2025 it reports gross proceeds, meaning the total dollar amount of your sales. Cost basis was added to the form for transactions from 2026 onward. That gap matters: a 1099-DA that lists proceeds without basis can read as though you owe tax on the entire sale amount, when you actually owe tax only on the gain above what you paid. Your own records are what bring that number back to reality.
One limit is worth knowing. Decentralized platforms and self-custody wallets do not send a 1099-DA, and Congress repealed the rule that would have required decentralized front-ends to report. Anything you did on-chain stays your responsibility to track, which is one more reason the software in the first section earns its keep.
A crypto-tax pro can reconcile your exchanges, wallets, and 1099-DA forms before anything reaches the IRS. We'll match you with one.

Cost basis is the number that decides how much of a sale is taxable, and the rules for tracking it changed in 2025. You now have to account for basis wallet by wallet, so each exchange account and each wallet keeps its own set of tax lots. Pooling everything into one universal average, which used to be common, is no longer allowed.
The tax software above handles this when you set it up correctly, so confirm two settings before you trust the numbers. Choose an accounting method you can defend, usually FIFO or specific identification, and apply it per account rather than across your whole portfolio. If you moved coins between wallets, check that the software carried the original purchase date and price along with them instead of resetting the basis at the transfer. A reset basis is one of the most common reasons a return overstates gains.
What to set up before you file
- Pick one piece of tax software and connect every exchange and wallet, current and old.
- Download each exchange's gain and loss report and full transaction export as backup.
- Find your 1099-DA forms for 2025 and check the proceeds against your own totals.
- Confirm your accounting method and that basis is tracked per wallet.
- Review every flagged transaction before you export Form 8949.
This does not replace a return that is filed correctly, but it means that when you do file, or hand the file to an accountant, the slow part is already done. The investors who get surprised in April are almost always the ones who waited until April to gather their records.
