Crypto tax positions, audited.
cryptoBASIS finds the errors and inconsistencies in your reported crypto tax positions — the missing cost basis, the broken lots, the gain-or-loss treatment that doesn't tie out. Built for individual taxpayers, small businesses, and the tax professionals who serve them.
Find what's actually wrong.
Eight detection rules check your CoinTracking export against your filed return for the kinds of errors that compound across years — missing basis, method drift, internal transfers coded as trades. Each finding comes with severity grading and, at Tier 2 and above, a dollar-impact estimate.
Defensible positions, in your facts.
At Tier 3, every finding includes a Position Memorandum — a written argument grounded in the License + Constructive Receipt framework, fitted to your specific transaction history. This is the document you hand to your CPA, or attach to an amended return, or hold in reserve in case the IRS asks.
From a multi-entity crypto operator.
cryptoBASIS productizes the audit its founder developed running it on his own crypto-active accounts — across DeFi positions, validator operations, and an IRA. Every indicator earned its place by surfacing a real error in real money that needed correcting.
Who cryptoBASIS is for.
cryptoBASIS serves three audiences with the same underlying audit.
Individual taxpayers
You've held crypto across multiple years, exchanges, and wallets. Your CoinTracking export shows numbers. Your return shows different numbers. cryptoBASIS finds where they disagree — and what to do about it.
Small businesses operating validators or DeFi positions
You run validators, hold treasury positions, or operate DeFi strategies through an LLC, S-Corp, or Self-Directed IRA. Multi-entity crypto creates audit exposure that consumer tax software wasn't built for. We were.
Tax professionals
You file returns for crypto-active clients and want a second opinion before signing. cryptoBASIS gives you a structured findings report with severity grading and Position Memoranda you can review, not a black-box number to defend.
What cryptoBASIS doesn't do.
cryptoBASIS is a software service. It is not tax preparation, not legal advice, not investment guidance, and not a custodian — we never hold or transmit your crypto, and we don't sign your return. The audit is a second pair of eyes on the work you or your tax professional already did. If you don't have a tax professional yet, we can help you find one; we can't replace one.
