How the DGT's position has evolved
Current position
The waiver of the objective estimation method must be formalized through a census declaration and not by the submission of the first quarter's installment payment. For express waivers, the revocation must be submitted in the month of December preceding the year in which it is to take effect. Professionals are exempt from installment payments if 70% of their income from the previous year was subject to withholding or payment on account.
The DGT's position has undergone a reversal regarding the method for waiving the objective estimation method. While the submission of the installment payment was previously accepted as a form of waiver, current doctrine requires the use of the census declaration form. The remaining criteria regarding the calculation of yields and exemptions remain without significant changes.
