  <Card title="Alguna Tax" icon="percent" href="/docs/tax/alguna-tax">
    Built-in, rule-based tax. You define rates and the conditions under which they apply.
  </Card>

  <Card title="External Tax Providers" icon="plug" href="/docs/tax/external-tax-providers">
    Connect Anrok or Stripe Tax. The engine determines tax from each line's tax code and the customer's location.
  </Card>

<Note>
  Tax codes apply to external providers only. Alguna Tax is driven entirely by the rules you configure.
