| Year | 2026 |

| Taxes involved | Property Transfer Tax (ITP) and Inheritance and Gift Tax (ISD) |
If you sell or buy a second-hand vehicle in Galicia, the process of changing ownership has just been significantly simplified. From October 5, 2026, the DGT and Galicia's Tax Agency (ATRIGA) automatically exchange data from the National Vehicle Registry electronically, eliminating the obligation to submit tax documentation in paper form at Traffic offices.
The agreement, published through the Resolution of September 29, 2026 from the General Technical Secretariat, updates previous agreements that operated under the now-repealed Law 30/1992, adapting to the Law 40/2015 on Legal Regime of the Public Sector and current data protection regulations.
What does this regulation establish?
The agreement articulates a bidirectional flow of information between two bodies:
| Body | What it shares | For what purpose |
|---|---|---|
| DGT — National Vehicle Registry | Data of the transferred vehicle (license plate, owner, characteristics) | Allow ATRIGA to verify that the tax corresponds to the correct transaction |
| Galicia's Tax Agency (ATRIGA) | Electronic report on compliance with ITP or ISD | Condition the authorization of the change of ownership at Traffic |
The practical result is clear: if ITP or ISD has not been correctly paid or self-assessed, Traffic will not process the change of ownership. And all of this happens without the citizen having to travel with papers between one office and another.
The agreement also expressly establishes that data exchange is strictly limited to what is necessary for each procedure, in compliance with the data minimization principle of data protection regulations.
Economic and operational impact
For the automotive sector in Galicia, this agreement has a fundamentally positive and operational impact: it reduces friction in second-hand vehicle transactions and speeds up processing times.
- Less bureaucracy for the buyer: it is no longer necessary to obtain and present in paper form the proof of ITP or ISD payment at the Traffic office. Verification is automatic.
- Greater cross-control for Tax Authority: ATRIGA accesses vehicle data directly from the National Registry, which reduces the margin for error or fraud in declaring the value of the transferred asset.
- Traffic management agencies: change in workflow: the process of handling the change of ownership is simplified in terms of physical documentation, but verification of prior tax compliance remains essential before initiating the Traffic procedure.
- Risk of blocking if there is tax non-compliance: if ITP or ISD is not correctly settled, ATRIGA's report will be unfavorable and Traffic will not complete the change of ownership.
Who does it affect?
- Buyers of second-hand vehicles in Galicia: must ensure they correctly settle ITP before initiating the change of ownership procedure.
- Sellers of vehicles in Galicia: in transfers by inheritance or donation, ISD must also be properly managed.
- Traffic management agencies and processing agencies: their workflow changes: tax documentation in paper form is no longer necessary, but prior verification of tax payment is now a sine qua non condition to complete the procedure.
- Dealerships and automotive sector companies in Galicia: benefit from faster processing in used vehicle sales operations.
- Citizens who receive vehicles by inheritance or donation in Galicia: ISD must be settled before being able to register the vehicle in their name at Traffic.
Practical example
Imagine that an individual in A Coruña buys a second-hand car for 8,000 euros from another individual. Until now, after self-assessing the ITP with ATRIGA, they had to go to the Traffic office with the proof of payment in paper form to complete the change of ownership.
With the new agreement in force from October 5, 2026, the process is as follows:
- The buyer self-assesses the ITP with ATRIGA (this step does not change).
- ATRIGA verifies payment and issues a favorable electronic report that is communicated directly to the DGT.
- The buyer (or their traffic management agency) initiates the change of ownership procedure at Traffic without needing to provide any tax documentation in paper form.
- Traffic consults ATRIGA's report and, if favorable, completes the change of owner.
If the ITP had not been settled or there was any issue, the report would be unfavorable and Traffic would block the procedure until the tax situation was resolved.
What should companies do now?
- Traffic management agencies in Galicia: update your internal procedures. Tax documentation in paper form is no longer submitted at Traffic, but you must verify that ITP or ISD is correctly settled before initiating any change of ownership procedure.
- Dealerships and used vehicle sales companies: inform your clients of the new workflow. The process is faster, but prior tax compliance remains mandatory and is now automatically verified.
- Individual buyers: do not initiate the procedure at Traffic without having previously settled the ITP. The system will block it if ATRIGA does not issue a favorable report.
- Recipients of vehicles by inheritance or donation: manage the settlement of ISD with your tax advisor before attempting to register the vehicle in your name.
- All affected parties: consult the complete regulation on the BOE (BOE-A-2026-20710) to learn the details of the agreement and its implications regarding data protection.
Frequently asked questions
When did the agreement between Traffic and Galicia's Tax Authority come into force?
The agreement between the Central Traffic Authority and Galicia's Tax Agency came into force on October 5, 2026, the date of its publication in the BOE through the Resolution of September 29, 2026 from the General Technical Secretariat.
Do I have to bring the ITP receipt in paper form to Traffic if I buy a car in Galicia?
No. With the new agreement, Galicia's Tax Agency communicates electronically to the DGT whether the ITP (or ISD, in case of inheritance or donation) has been correctly settled. It is no longer mandatory to provide tax documentation in paper form at Traffic offices in Galicia.
What happens if I haven't paid the ITP before going to Traffic?
If ITP or ISD is not correctly settled, Galicia's Tax Agency will not issue a favorable report to the DGT. Traffic will condition the change of ownership to that report, so the procedure will be blocked until the tax situation is regularized.
Does this agreement only affect Galicia or also other regions?
This agreement is exclusive between the Central Traffic Authority (DGT) and the Tax Agency of Galicia (ATRIGA). It only applies to vehicle transfers subject to taxation in Galicia. Other autonomous communities may have similar agreements of their own, but this specific agreement does not affect them.
What regulation does this agreement repeal or update?
The agreement updates previous agreements between both bodies that were based on Law 30/1992, now repealed. The new agreement adapts to Law 40/2015 on the Legal Regime of the Public Sector and current data protection regulations, which require that the exchange of information be strictly limited to the data necessary for each procedure.
