Vehicle owners in Galicia must fulfill tax obligations to transfer ownership

The Spanish Official State Gazette (BOE) has published the Resolution of September 29, 2026, which formalizes the agreement between the Central Traffic Headquarters (DGT) and the Galician Tax Agency (Atriga). This agreement establishes a telematic exchange of information regarding the National Vehicle Registry to enhance the management, collection, and inspection of taxes within the Autonomous Community of Galicia.

What changes

The core of this agreement lies in the interoperability between the national traffic authority and the regional tax administration. According to the first clause (cláusula primera) of the agreement, the DGT will grant Atriga access to data from the National Vehicle Registry. This access is designed to serve two primary purposes:

• Facilitating ownership transfers: The DGT will only process changes in vehicle ownership once Atriga has provided its conformity, confirming that the taxpayer has fulfilled their tax obligations (cláusula primera).
• Strengthening tax oversight: The exchange allows Atriga to perform more efficient management, collection, and inspection of both regional taxes and taxes ceded by the State (cláusula primera).

By integrating these systems, the administration ensures that the transfer of a vehicle is inextricably linked to the settlement of the relevant taxes, specifically the Property Transfer Tax Spain: Rates, Exemptions & ITP and the Inheritance and Gift Tax (ISD).

Context

Historically, the management of vehicle transfers and the collection of associated taxes operated in somewhat separate administrative silos. While the DGT maintains the technical registry of all vehicles in Spain, the regional tax agencies are responsible for the liquidity and collection of taxes such as ITP and ISD. This administrative gap sometimes allowed for delays or discrepancies between the physical transfer of a vehicle and the actual tax settlement.

This new agreement is framed within the principles of Law 40/2015 on the Legal Regime of the Public Sector and Law 39/2015 on Common Administrative Procedure. These laws mandate that Public Administrations must communicate with each other through electronic means to ensure interoperability, efficiency, and the protection of personal data. By automating the verification of tax compliance, the administration moves toward a "paperless" model that reduces the administrative burden on the citizen while increasing the certainty of tax collection.

Who is affected and how

The impact of this agreement is specific to those involved in vehicle transactions where the taxable event or the residence of the parties falls within the jurisdiction of Galicia.

• Individuals (Particulars): Any person residing in Galicia or performing a vehicle transaction within the region will be affected. When buying or receiving a vehicle, the DGT will check with Atriga to ensure the taxes (ITP or ISD) have been correctly declared and paid before the new owner's name can be registered.
• Freelancers (Autónomos): Professionals who use vehicles for their business activities in Galicia must ensure that any transfer of these assets complies with regional tax regulations. The automated link between DGT and Atriga means that any pending tax issues related to the vehicle could block the administrative transfer of ownership.
• SMEs and Companies (Pymes): Businesses managing fleets in Galicia will face stricter oversight. The transfer of company vehicles must be backed by the appropriate tax documentation, as the DGT will now rely on Atriga's electronic confirmation to finalize any change in the registry.

What to do and when

This regulation is an administrative agreement between two public bodies; therefore, it does not impose a new deadline or a specific filing obligation on citizens or companies. However, it changes the operational reality of vehicle transfers in Galicia.

If you are planning to buy, sell, or inherit a vehicle in Galicia, you must ensure that the tax settlement is completed promptly. Because the DGT will now require Atriga's "conformity" to process the change of ownership, any delay in paying the Property Transfer Tax or the Inheritance and Gift Tax will directly result in a delay in the official registration of the vehicle in your name.

We recommend verifying the tax status of any vehicle transaction in advance to avoid administrative bottlenecks at the DGT. For complex cases involving large fleets or international residents, it is advisable to consult with the tax specialists at BMC to ensure full compliance with Galician regional regulations.
