How the DGT's position has evolved
Current position
In successive performance operations, such as the supply of electricity, the applicable tax rate is the one in force at the time of accrual. Accrual occurs when the portion of the price comprising each charge becomes due, according to the terms of the contract. This moment of exigibility is independent of the period in which the consumption took place or the moment of payment.
The DGT's position remains constant throughout the analyzed sequence. The criterion establishes that the applicable rate depends on the regulations in force at the time each part of the price becomes due, regardless of when the actual consumption occurred. No changes in doctrine are observed, but rather a reiteration of the same accrual principle.
