# TaxMaxi Documentation

> TaxMaxi is an API-first crypto tax platform. Connect exchange accounts, sync transactions, and compute tax-ready summaries via REST API, CLI, or JavaScript SDK.

TaxMaxi turns raw exchange and onchain activity into machine-readable, tax-ready events. Whether you're a fintech integrating compliance into your product, a developer building an AI agent that needs deterministic tax logic, or an individual who wants to automate their crypto taxes from the terminal — TaxMaxi gives you a clean REST API, a JavaScript SDK, and a CLI to get the job done.

The first supported jurisdiction is Germany, with FIFO-based capital gains and income calculation aligned with current German tax law.

## Get started in three steps

<Steps>
  <Step title="Create an account">
    Register with your email and password via `POST /auth/register`, or use OAuth with Coinbase. You'll receive a session token to authenticate all subsequent requests.
  </Step>

  <Step title="Connect a source">
    A source is a connected exchange account or onchain wallet. Use the CLI (`tax coinbase`) or the Sources API (`POST /v1/sources`) to connect your first account and trigger a sync.
  </Step>

  <Step title="Calculate your taxes">
    Once a sync completes, call `POST /v1/sources/:sourceId/tax` with the target year and jurisdiction to get a structured tax summary — taxable gains, losses, tax-free gains, and income totals.
  </Step>
</Steps>

<Note>
  TaxMaxi is pre-launch and currently focused on German tax law (jurisdiction: `germany`). Coinbase is the first supported exchange provider.
