INDIVIDUALS
Your history has gaps
Exchange exports disagree, transfers do not match, or older purchase records are missing. Often it shows up as a blank cost basis on Coinbase or a 1099-DA.
For Coinbase and Binance users
If your exchange shows missing purchase history, or transfers that do not match, I rebuild the trail from your exports and hand you one clean, documented file for your accountant or tax software.

INDIVIDUALS
Exchange exports disagree, transfers do not match, or older purchase records are missing. Often it shows up as a blank cost basis on Coinbase or a 1099-DA.
ACCOUNTANTS
You need a documented source map, visible assumptions, and a list of open questions before you decide the tax treatment.
Tax season 2027
Brokers started sending Form 1099-DA for 2025. Many show what you sold but not what you paid, especially for coins bought before 2026 or moved in from another wallet. A blank basis does not mean you paid nothing, but you will need your own records to show what you paid. Your accountant or tax software decides how to report it.
What you receive
A reviewable record of what changed, why it changed, and what still needs a decision. Nothing is hidden. Open a sample pack (fictional data).
01
Normalized supported records with source references.
02
What was received, used, missing, or left outside scope.
03
Human-reviewed changes and the reasoning attached to them.
04
Questions and evidence gaps that still need a client or adviser.
How it works
We confirm fit and scope before asking for payment or evidence.
01
Tell us the years, sources, approximate volume, and what appears to be wrong.
02
For an accepted case, we map gaps, blockers, and the evidence needed before reconstruction.
03
Supported records are normalized and matched with assumptions kept visible.
04
You receive an Evidence Pack for review with your accountant or adviser.
Qualification coverage
I confirm exactly what I can rebuild in writing. A source on this list is a starting point, not a promise that every export format or transaction type is supported.
01
Supported case by case when the file matches the verified Coinbase Retail Transaction History contract.
02
Specific spot-history exports are supported after case-specific secure intake is enabled.
03
Qualified as public evidence only; no wallet access, credentials, or custody.
04
Qualified for documented source notes and visible unresolved assumptions.
Launch scope covers supported exchange CSVs, public wallet evidence, and manual opening lots. Complex DeFi, NFTs, bridges, and protocol-specific tax classification require separate review and may be declined.

Questions before you start
No. I organize records. Your accountant decides how to report them. More on the methodology page.
No. Qualification, clarification, scope confirmation, and case updates can happen in writing.
Not at launch. We confirm exact source coverage during qualification and decline work that cannot be handled responsibly.
No. The public form is metadata-only. If the case fits, evidence collection is a separate private step.
