How the DGT's position has evolved

Settled doctrine High confidence 12 rulings · 2014–2026

Current position

To modify the tax base through subsequent discounts or the cancellation of transactions, it is mandatory to issue and send a credit note. The reduction of the deduction must be carried out in the period in which said credit note is received. If the rectification increases the tax base, the taxpayer may apply it in the period of receipt or in subsequent periods, subject to a four-year limit.

The DGT's position remains constant regarding the need to use credit notes to formalize discounts that affect the tax base. The evolution focuses on technical precision concerning the timing of accrual and the treatment of the deduction following the receipt of the document. No changes in criterion are observed, but rather greater specificity regarding the deadlines and accounting effects of the rectification.

Turning points

  1. V1412-17

    Establishes that the discount is only effective when the price reduction is irrevocable, requiring the issuance and sending of a credit note.

  2. V0226-26

    Specifies the temporal treatment of the deduction, indicating that the reduction must be made in the period of receipt of the credit note.
