FAQs about TicketBAI.

TicketBAI or TBAI is a software-based fiscalization system that is being implemented in the Basque Country between 2021 and 2026 and enforces fiscalization requirements. TBAI thus enables tax offices to control income from economic activities, especially those with end customers. The system is designed to prevent manipulation of tax-related information and prevent fraud.

TicketBAI is a joint project of the Basque Government and the regional tax administrations of the three Basque provinces: Gipuzkoa, Araba, and Bizkaia.

In Bizkaia, TicketBAI is part of the larger control strategy BATUZ. This includes the declaration of a registration book with economic transactions (LROE), which allows the tax administration to prepare VAT drafts.

TicketBAI applies to all natural and legal persons and entities that carry out an economic activity that falls within the jurisdiction of the Basque Tax Administration in personal tax income or society income, as established in the Economic Agreement with the Autonomous Community of the Basque Country (Law 12/2012, of May 23) — simplified, a tax address in the Basque Country.

The corresponding legislation specifies which taxpayers will be exempted from this obligation.

The deadlines for implementing TicketBAI vary by region.

Gipuzkoa: From 01.01.2021: Start of voluntary period. From 01.07.2022: Start of mandatory period. Gradual addition of economic segments until 01.06.2023.

Álava: From 01.01.2022: Start of voluntary period. From 01.04.2022: Start of mandatory period. Gradual addition of economic segments until 01.12.2022.

Bizkaia: From 01.10.2021: Start of voluntary period. From 01.01.2024: the mandatory period of BATUZ (including TicketBAI) has been extended from 01.01.2024 to 01.01.2026, gradually for different types of companies and with adaptation periods of six months at a time.
