How the DGT's position has evolved

Stable position Low confidence 451 rulings · 2014–2026

Current position

Formal obligations vary depending on the transaction: in rehabilitation works subject to a reduced rate, the tax amount must be rectified via a credit note if the rate applied was higher than the correct one. For transport services acting in one's own name, the travel agency regime applies with a general VAT (IVA) rate of 21%, unless the client is a taxable person with the right to deduction and opts for the general regime. For discounts applied after the transaction, the tax base is the total consideration, and a credit note must be issued to reduce it.

The sequence does not show a doctrinal evolution on a single concept, but rather addresses various formal obligations in different scenarios. There is no change in position, but rather an application of specific rules for each case (works, discounts, transport, or bad debts). The DGT's position remains constant in requiring a credit note to correct tax bases or tax amounts.
