Frequent questions

Joint project of the Provincial Treasury and the Basque Government to implement a series of legal and technical obligations in billing software with the aim of putting an end to tax fraud and tax evasion.

Ticket BAI will allow the Provincial Treasury to track all the invoices issued in the region, especially those for activities that are normally charged in cash. The information obtained from this monitoring will be used to help taxpayers comply with their tax obligations.

Affects the Regional Treasury of Bizkaia, Gipuzkoa and Álava: natural and legal persons who carry out economic activities in this territory must use billing software that meets a series of requirements.

Any company or freelancer with headquarters in Vizcaya will be obliged to use this system from its entry into force. Most taxpayers in Gipuzkoa and Álava must also adopt TicketBAI, although there is one exception: those over 60 years of age who are exempt in Gipuzkoa and Álava as long as they have not had employees during 2021 and do not belong to professions that are required to register.

Ticket BAI includes any legal entity without legal personality that has an economic activity and is subject to the rule of the Provincial Treasury in the Company Tax or Personal Income Tax in the Basque Autonomous Community.

Since the implementation of Ticket BAI, all companies and freelancers billing in the Basque Country must use billing software that meets the Government’s requirements. Don’t wait until the last minute!

You must generate an electronically signed XML file (Ticket BAI File), which must be sent to the Treasury in real time.

The image of the invoice must include a document identification code (TBAI code) and QR code.

The computer program used to carry out this process must be officially registered as guarantor software.

The Ticket BAI system will identify each of the invoices issued in the territory. Thus, the Provincial Treasury will be able to track all the transactions that are carried out and collect their due taxes.

1 For each invoice that is issued, the software will create an XML file.

2 It will be sent to the respectiv Foral Treasury.

3 This will assign a QR code and an identification code.

4 Once this is done, the Hacienda will return the file to the issuing software.

It is at this moment when the image of the invoice can be generated. This process is instantaneous and, at the end, the buyer will have their invoice validated.

You can start working with the Ticket BAI system on a voluntary basis right now, since the voluntary period began in Bizkaia in October 2020, in Gipuzkoa in January 2021 and in Álava in January 2022.

Rewards: Companies that adopt the system early will be eligible for grants.

Taxpayers in Bizkaia may apply for a 30% deduction on the expenses involved in the implementation of Ticket BAI. These include the acquisition of equipment, terminals and programs.

A deduction of up to 15% in Personal Income Tax or Companies is also established for 2 years for the freelancer and companies that implement Batuz.

Gipuzkoa and Álava will allow the deduction of 60% of income tax or companies for anticipating at least one month the fulfillment of the Ticket BAI obligation, based on the expenses incurred for the adaptation to the new system.

Sanctions: any type of alteration of data, destruction or manipulation of the software will be sanctioned with fines of 20% of the turnover of the previous year, which may not fall below 20,000 euros.

Likewise, companies that repeat illegal practices with respect to Ticket BAI will have their fine increased to 30% of the figure for the previous year, which may not be less than 30,000 euros.
