How the DGT's position has evolved
Current position
In the event of a rectification resulting in the refund of an undue payment, the Administration must pay late payment interest from the date of the payment until the payment order. Regarding penalties, late payment interest is not required during the voluntary payment period following the administrative resolution. The calculation of these interests begins the day after the end of said period and ends on the day of the payment.
The DGT's position remains stable regarding the right to the refund of undue payments through rectification. The evolution shows greater technical specificity by detailing the calculation of late payment interest, both in refunds due to rectification and in the regime applicable to penalties.
