How the DGT's position has evolved
Current position
When subsidies affecting the basis of a deduction are received, such as in energy efficiency renovation works, the tax situation must be regularized to exclude said amounts. This regularization requires adding the unduly deducted amounts to the net tax liability, along with the late payment interest provided for in the General Tax Law. The procedure complies with the provisions of article 59 of the Tax Regulation.
The sequence does not show a doctrinal evolution, but rather a dispersion of different scenarios under the concept of regularization. The rulings address heterogeneous topics such as foreign pensions, primary residence, energy efficiency, or unemployment benefits; therefore, there is no trajectory of change in a single criterion.
