Hello.
I have a problem making retainer invoices in Spain.
I issue a retainer invoice with taxes included.
Then I apply that retainer invoice to a total commercial invoice. However, according to Spanish law, you should only deduct the total amount of the tax base from the invoice, since otherwise you would be applying the rates in duplicate.
Once you make the sale or provide the complete service, you must issue an invoice for the total. In this new invoice you will discount the retained payment received in advanced. Obviously, the new invoice will only include VAT pending.
Is there any way where we can indicate that the registered payment already contains taxes, so in the total invoice the taxes are discounted too?
