How the DGT's position has evolved
Current position
The reduction of the tax base for alimony allows for the deduction of annuities paid by judicial decision to persons other than children, such as the mother. The remainder of said reduction is applied to the savings tax base. The nature of the obligation and the payment must be proven as facts before the Administration.
The sequence presents a thematic dispersion that prevents tracing a single doctrinal evolution regarding the reduction of the tax base. Isolated criteria are observed regarding the 95% reduction in the transfer of shares and regarding deductions for contributions to social security systems or alimony payments. There is no line of doctrinal continuity between the analyzed rulings.
