You have years of trades and no clean cost basis.

Exchanges closed, wallets moved, software gave up. We rebuild the history from the chain and the records you still have, then prepare the returns that were missed or need amending.

WHO DOES THE WORK

Prepared in Skokie by people who know what the IRS looks for

Your return is prepared by the Gordon Tax team in Skokie, Illinois. Gordon Tax, LLC was founded by Andrew Gordon, a tax attorney and CPA, and has focused on crypto tax since 2014.

What to have ready

Whatever you still have: exports, emails, statements, bank records showing purchases, and any return filed for the missing years.

Frequently asked questions

We reconstruct from the blockchain side and any statements or emails you have. Gaps are documented rather than guessed.

As many as you need. The IRS generally wants the last six years of returns when someone catches up, but we scope each case individually.

Filing accurate returns is what reduces exposure.

SCHEDULE A CONFIDENTIAL CONSULTATION
