Practical manual for Income Tax 2024. Part 1

In general

The determination of the full quotas of the PIT It is carried out from the two components into which the taxpayer's taxable base is divided:

  • General taxable base to which the progressive rates of the state and regional scales are applied.

  • Taxable savings base to which the rates of the corresponding state and regional scales are applied.

    On this general scheme, certain specialties are incorporated, derived, on the one hand, from the very nature of the PIT as a tax partially transferred to the Autonomous Communities and, on the other hand, from the specific liquidation regime assigned to the personal and family minimum, to exempt income, except to determine the tax rate applicable to the remaining income, also called "exempt income with progressivity" and to the annuities for child support paid by court order.

State tax and regional tax

Personal Income Tax is a partially transferred tax, with a limit of 50%., in the terms established in Organic Law 8/1980, of September 22, on the financing of the Autonomous Communities, last modified for the purposes of PIT, by Organic Law 3/2009, of December 18 (BOE of December 19).

As a result of the transfer of personal income tax, two phases are distinguished within the tax settlement procedure: one state-wide and one regional-wide. Thus, both the general taxable base and the savings taxable base are subject to a state tax and an autonomous tax, which give rise to a state and an autonomous rate. Based on the latter, the portion of tax debt that is transferred to each Autonomous Community of the common regime is determined.

With regard to the autonomous quota , it should be noted that the Autonomous Communities of the common regime may, in accordance with the provisions of article 46.1 of Law 22/2009, of December 18 ( BOE of December 19), assume regulatory powers in determining the amount of the personal and family minimum applicable for the calculation of the autonomous tax and on the autonomous scale applicable to the general taxable base.

Regarding the amount of the personal and family minimum applicable for the calculation of the regional tax , both the Autonomous Communities of Andalusia, Galicia, the Balearic Islands, the Canary Islands, La Rioja and the Communities of Castilla y León, Catalonia, Madrid and the Valencian Community, have approved the amounts of the personal and family minimum that taxpayers resident in 2024 in their territory must use for the calculation of the regional tax. These autonomous amounts are discussed in Chapter 14 .

To the Communities of Castile and León, and Catalonia (because their amounts do not differ) as well as to the rest of the Autonomous Communities that have not exercised such regulatory competence, the amounts of the personal and family minimum established in the Law of the PIT.

As for the autonomous scales, all the Autonomous Communities have approved, In accordance with the provisions of article 46 of Law 22/2009, which regulates the financing system of the Autonomous Communities of the common regime and Cities with Statute of Autonomy, and in article 74 of the Law of PIT, the corresponding autonomous scales applicable in the 2024 financial year which are detailed below.

However, taxpayers with habitual residence in Ceuta and Melilla are subject to the autonomous scale set out in article 65 of the Law of PIT (Thirty-second Additional Provision of Law PIT).

Likewise, in the case of taxpayers with habitual residence abroad due to the occurrence of any of the circumstances referred to in articles 8.2 and 10.1 of the Law of PIT, the determination of the total full quota presents certain special features whose commentary is made in a specific section of this Chapter ("Tax applicable to Personal Income Tax taxpayers residing abroad").

Application of the personal and family minimum

Regulations: Articles 63.1.2 and 74.1.2 Law PIT

In order to ensure the same tax savings for all taxpayers with the same personal and family situation, regardless of their income level, in the current Law of PIT The personal and family minimum does not reduce the income of the tax period, but rather forms part of the general taxable base up to the amount of the latter and, where applicable, of the savings taxable base for the remainder.

The application of the personal and family minimum and the determination of the full quotas of the PIT, are represented graphically in the diagram shown in the following section:
