Crypto tax documentation prep
Every tax season, people show up at accountants’ offices with five wallets, three dead exchanges, a DeFi habit, and no records. Most CPAs don’t want to reconstruct on-chain history, and specialist crypto-tax firms price for whales.
This service does the reconstruction and documentation layer: a clean, sourced activity file the client’s regular tax preparer can actually work from. You prepare documentation; the CPA prepares the return.
The job
A client gives you their wallet addresses and exchange records. You run the citation-verified wallet review (the flagship call, $12, which reconstructs activity with verification rather than guesswork), the on-chain investigation for wallets with murky history, and jurisdiction rules checks for where they file. Deliverable: an organized documentation pack (activity summary, flagged events like staking income or NFT sales, jurisdiction notes, open questions for the CPA).
Off-season, the same skills sell as wallet security reviews: drainer-protection scans and security posture checks for people holding meaningful balances.
Who it suits
Crypto-native people with an organizational streak: the friend who actually kept records. Bookkeepers adding a crypto specialty are a perfect fit and command a premium fast.

Engine prices are the live public catalog prices, the same sheet agents pay. No subscription is required to use them.
The licensing question
The boundary: preparing documentation is unlicensed; preparing or signing tax returns for compensation triggers preparer rules (PTIN in the US, equivalents elsewhere), and giving tax advice is the CPA’s or tax attorney’s job. Your deliverable ends with "questions for your preparer," not answers to them. Kept there, you’re a bookkeeping-adjacent documentation service, and CPAs will refer clients to you rather than turn the work away. This page is educational information, not tax advice.
How the engine does the heavy lifting
Citation-verified wallet tax review, on-chain wallet investigation, drainer-protection scans, and per-jurisdiction crypto tax rules. The review’s track record endpoint is public and free.

- Run the full documentation pack on your own wallets first. Your own messy history is the practice ground.
- Price per wallet-complexity tier, flat, with the engine’s $12 review cost baked in.
- Introduce yourself to three local CPAs in January with a one-page "what I hand you" sample. You’re solving their problem, not competing.
- Book off-season security reviews with the same client list; it smooths the seasonality.
