# VAT and tax IDs

> Add a VAT, GST or other tax ID so it appears on your Ocoya invoices.

A tax ID on file appears on your invoices, which is usually what your accountant needs in order to reclaim the VAT.

## Add a tax ID

<Steps>
  <Step title="Open Billing">
    Select **Billing** in the sidebar.
  </Step>

  <Step title="Select Payment & invoices">
    This opens Stripe's billing portal.
  </Step>

  <Step title="Update your billing information">
    Under billing information, add your company name and address, then add the tax ID.
  </Step>

  <Step title="Choose the ID type">
    Stripe asks which kind — VAT, GST, ABN, EIN and many others. Pick the one for your country and enter the number in that country's format.
  </Step>
</Steps>

You can hold more than one, which matters if you're registered in several countries.

## It only affects future invoices

An invoice is fixed once issued, so a tax ID added today appears on your **next** invoice, not on past ones. If you've just subscribed and need the ID on your first invoice, add it before the renewal rather than after.

## Common problems

**"My number was rejected."** Stripe validates the format per country and, for EU VAT, checks the number is real and active. Enter it with the country prefix (`LT100004801314`, not `100004801314`) and confirm it's active in the [VIES checker](https://ec.europa.eu/taxation_customs/vies/).

**"I still get charged VAT."** Whether VAT applies depends on your country and business status, not just on holding an ID. A valid ID in the right circumstances removes it from future invoices; it never changes an invoice already issued.

**"I need a past invoice reissued with my ID."** Contact support with the invoice number.
