Temporal, subjective and objective scopes of the deduction

Time scope of the deduction and tax period in which the deduction is applied

The deduction is applicable to amounts paid from on October 6, 2021 to on December 31, 2023 for works carried out during said period that meet the conditions and requirements indicated in the following sections.

Extension of the temporal scope of this deduction until December 31, 2023: Article 21 of Royal Decree-Law 18/2022, of October 18, approving measures to strengthen the protection of energy consumers and to contribute to the reduction of natural gas consumption in application of the "Plan + security for your energy (+SE)" as well as measures regarding the remuneration of personnel in the service of the public sector and the protection of temporary agricultural workers affected by the drought ( BOE of October 19) has modified, with effect from January 1, 2023, the temporal scope of this deduction until December 31, 2023.

However, the deduction will be applied in the tax period in which the energy efficiency certificate issued the works have been completed is issued.

When certificate issued in a tax period subsequent to that in which amounts were paid for such works, the deduction will be applied in said subsequent tax period taking into consideration the amounts paid from October 6, 2021 (date of entry into force of Royal Decree-Law 19/2021, of October 5, on urgent measures to promote building rehabilitation activity in the context of the Recovery, Transformation and Resilience Plan), until December 31 of the tax period in which the certificate is issued.

In any case, said certificate must be issued before January 1, 2024 (after the modification provided for in article 21 of Royal Decree-Law 18/2022, of October 18).

Objective scope of the deduction

A. Type of housing that entitles you to the deduction

The following homes are eligible for deduction if they are carried out to reduce the heating and cooling demand:

• The taxpayer's habitual residence

• Any other dwelling owned by the taxpayer that is rented for use as a dwelling at that time or in expectation of rental, provided that, in the latter case, the dwelling is rented before December 31, 2024 (after the modification provided for in article 21 of Royal Decree-Law 18/2022, of October 18).

  It is considered that this is a lease of a property for use as a dwelling when, in accordance with the provisions of article 2 of Law 29/1994, of November 24, on Urban Leases (LAU), the lease falls on "a habitable building whose primary purpose is to satisfy the tenant's permanent housing need."

Note: Likewise, this deduction may be applied to works carried out on single-family homes.

Works carried out in:

• The parts of the dwellings affected by an economic activity.

• Parking spaces, storage rooms, gardens, parks, swimming pools and sports facilities and other similar elements.

• Homes available to their owners (second homes) that are not rented or expected to be rented (although in the latter case, if the home is not rented before December 31, 2024 - after the modification introduced by article 21 of Royal Decree-Law 18/2022 -, they are also excluded from the possibility of applying the deduction).

Note: This deduction is not applicable to new-build or newly constructed homes since, as in these cases there is no energy efficiency certificate prior to and after the works, as required by the law, the corresponding reduction with respect to the previous situation cannot be accredited.

B. Improvement works that give the right to the deduction

• The works that qualify for the deduction are those carried out from October 6, 2021 to December 31, 2023 (after the modification provided for in article 21 of Royal Decree-Law 18/2022, of October 18) to reduce the demand for heating and cooling.

  Heating and cooling energy demand is the energy required to maintain the internal comfort conditions of the building.

  For these purposes, it will be understood that the heating and cooling demand of the home has been reduced when the sum of the heating and cooling demand indicators in the energy efficiency certificate issued by the competent technician after the works were carried out is reduced by at least 7% compared to the one issued before the start of the works.

  Note:  Please note that ## amounts paid corresponding to costs relating to the installation or replacement of equipment that uses fossil fuels are not eligible for deduction.

• To prove compliance with the requirements for applying this deduction, the efficiency certificates issued before and after the works will be necessary.

  Energy efficiency certificates issued before the start of work will be valid to prove compliance with the requirements provided that a period of two years has not elapsed between the date of issue and the date of start of work.

  The energy efficiency certificates issued after the completion of the works determine the tax period in which the deduction is applied and must be issued before January 1, 2024 (after the modification provided for in article 21 of Royal Decree-Law 18/2022, of October 18).

  Note: Certificates are the only means established by the Personal Income Tax Law to prove the reduction or improvement. Therefore, if the corresponding certificate is not available prior to the start of the works or the one issued by the competent technician after the works have finished, compliance with the required requirements is not accredited and, consequently, the deduction cannot be applied.

•  In any case, energy efficiency certificates must have been issued and registered in accordance with the provisions of Royal Decree 390/2021, of June 1, which approves the basic procedure for the certification of the energy efficiency of buildings.

Note: Taxpayers entitled to this deduction must complete the information requested about the property in the corresponding section of Annex A.2 of the declaration, the NIF or NIE of the person or entity that carried out the work, the dates of the energy efficiency certificates before and after the works, as well as the energy demand for heating and cooling shown in each of them, data that may be extracted from the sum of the global indicators of heating and cooling demand contained in section 3 of Annex II of each of the certificates, and the amounts paid.

Subjective scope of deduction

taxpayers who hold the title of owner of the property is the subject of such works may apply this deduction.

Each co-owner of the home may claim a deduction for the amounts paid for the works in the part that proportionally corresponds to their percentage of ownership in the habitual residence, regardless of whether the invoice for the works was issued solely in the name of one of the co-owners of the home.

Therefore, the bare owners, usufructuaries and tenants are excluded.
