Determination of the general taxable base

Regulations: Art. 50.1 and 3 Law IRPF

The general taxable base is the result of reducing the general tax base by the amount of the reductions discussed so far in this same Chapter. The reductions are applied to reduce the general tax base, in the order in which they have been discussed, without the latter being able to result in a negative result as a consequence of such reductions.

Negative general taxable base

The general taxable base may be negative when the general taxable base is negative because its negative components are greater than its positive components. In these cases, none of the reductions mentioned so far may be applied.

If the general taxable base turns out to be negative in the terms discussed above, its amount must be offset against the positive general taxable bases obtained in the following four years .

The offset must be made in the maximum amount permitted in each of the following years and may not be made outside the period referred to in the previous paragraph, by accumulating negative general taxable bases from subsequent years.

Note: the amounts of the negative general taxable bases for the years 2015 to 2018 pending offset at the beginning of the year, those applied in the declaration and the remainder pending application in future years, as well as the amount of the negative general taxable base for 2019 that remains to be offset in the following 4 years, must be recorded in Annex C.3 of the declaration in the section "Negative general taxable bases pending offset in the following years".

Compensation rules in joint taxation

The general negative taxable bases determined in joint taxation will be offset, exclusively, in the case of subsequent individual taxation, by those taxpayers to whom they correspond in accordance with the rules on individualization of income contained in the Tax Law.
