Orla keeps the cost of every coin you hold and seals the year for your accountant. How your tax law treats it is their call.

## How it works

- **One method, the whole history.** FIFO, LIFO or HIFO, with the date and cost of every lot kept through each swap. Switching restates every year, so it is refused while a year is sealed.
- **Priced at its minute.** A trade takes the price of its minute. A move between your own wallets is not income. Orla books a deposit on Aave as a move, not a sale; how your tax law treats it is your accountant's call.
- **Book against the chain.** For every wallet and asset, what the book holds beside what the address holds, and the difference. A roll-forward shows the year adds up.
- **A seal that tells.** The year closes in four steps: what is not ready, does it reconcile, the figures, the seal. A sealed year keeps its filed figures and says when a recount drifts.

## Questions

**Does Orla file our crypto taxes?** No. It keeps the cost basis and the year's figures as files your accountant imports. The filing and the advice stay with them.

**What about coins that came from outside?** They wait under Cost basis to fill in. You state what they cost, and the line is marked as stated by you in every export.
