If your business is based in Spain, you can set a tax regime (Régimen) against each customer record in the Cloud POS Back Office. This field is used to indicate the customer's tax classification, and will automatically set their Tax Exempt status where relevant.
Setting the Régimen
To set a customer's Régimen, open their customer record in the Back Office and scroll to the Impuestos y precios (Taxes & Prices) section. You will see the Régimen dropdown here, along with the Exento de impuestos (Tax Exempt) checkbox:

The following options are available in the Régimen dropdown:
- Ninguno – no regime set.
- General – standard tax regime.
- Intracomunitario – intra-community transactions (for example, EU business customers).
- Extracomunitario – extra-community transactions (outside the EU).
- IGIC/IPSI – applies to customers in the Canary Islands, Ceuta or Melilla.
Select the appropriate option and click on Save Pending Changes in the bottom right.
Tax Exempt behaviour
Selecting certain Régimen options will automatically tick the Exento de impuestos (Tax Exempt) checkbox as a convenience:
- Intracomunitario, Extracomunitario, or IGIC/IPSI — Tax Exempt will be automatically ticked when one of these options is selected.
- General or Ninguno — Tax Exempt will not be automatically changed. If it has already been ticked manually, it will remain ticked.

The Tax Exempt checkbox remains independently editable at all times — the automatic tick is a convenience, not a lock. You can untick it manually after selecting a Régimen if needed.
