Get your records together

Download the full transaction history (CSV) from every exchange you used — all years, not just this one. What to keep, and for how long
Save the transfer records for every wallet-to-wallet move, so a deposit never looks like a purchase. Why transfers are not sales
Find the original purchase record for anything you transferred into an exchange. Rebuilding a missing basis
List every staking, mining, and airdrop receipt with its dollar value on the day it arrived. How reward income is taxed
Write down your cost-basis method — FIFO, HIFO, or specific ID — and use it consistently. The methods, compared

Reconcile your 1099-DA

Run every sale on the form against your own basis, row by row. Open the 1099-DA reconciler

Before you file

Confirm the holding period on every lot — more than a year is long-term. 2026 rates, short vs. long
Put every sale on Form 8949 with the right category and adjustment code. Form 8949, line by line

After you file

Keep the return, Form 8949, and the records behind them together for at least three years. The folder system
If a CP2000 matching notice arrives, treat it as a proposal to answer, not a bill to pay. Notices, audits, and your options
Found an error later? Amend with Form 1040-X rather than ignoring it. Common mistakes and their fixes
Harvest any remaining losses before December 31 closes the tax year. Estimate a harvest
Put next year’s dates on your calendar now, while you remember how this season felt. The 2026–2027 calendar

Educational estimate only — not tax, legal, or accounting advice. CryptoTaxAI does not file with the IRS and does not replace Form 8949, Schedule D, or a qualified tax professional. Verify figures against your records and current IRS publications.

The step most people get wrong

Reconciling the 1099-DA against your own basis — before you file, not after the notice arrives. It takes two minutes per sale.

No. Your ticks are kept in this browser’s localStorage so the list is still here when you come back. Nothing is uploaded, and the Reset button erases them.

No. The checklist is a work plan: it walks the records, reconciliation, and forms in the right order. Your actual return still reports every sale on Form 8949 and Schedule D, by hand, in software, or through a tax professional.

The records steps can start any time — exchange exports are easiest to pull while the tax year is fresh. The reconciliation steps start when your first 1099-DA lands, in mid-February.

Your documented records. You report your actual cost basis on Form 8949 and reconcile the broker’s figures to it — you do not replace your numbers with the form’s, and you do not ignore the form either. The reconciler shows the size of the difference before you file.
