How the DGT's position has evolved
Current position
In Personal Income Tax (IRPF), parents with shared custody have the right to the minimum allowance for descendants, which must be prorated in equal parts. When exercising this right, they cannot apply the special rules for child support annuities under Articles 64 and 75 of the Law 35/2006 on Personal and Wealth Income Tax (LIRPF). The child support annuity regime is only applicable when the parents do not have the right to the minimum allowance for descendants.
The DGT's position on the application of scales and special regimes has shown an evolution towards delimiting the exclusivity between benefits. While in 2020 the option between the minimum allowance for descendants or the child support regime was permitted, the 2024 ruling establishes that the existence of the right to the prorated minimum allowance excludes the application of child support annuities.
Turning points
-
Establishes that the right to the minimum allowance for descendants in shared custody prevents the application of the special rules for child support annuities, limiting the option that was raised in previous rulings.
