Ask yourself about TicketBAI in Bizkaia and its entry into force is a legal and strategic issue. Especially if you operate in this historic Basque territory. Since 2024, this system has been progressively implemented and, today, it is a full legal requirement that influences invoicing, internal control, and tax data governance.
For medium and large companies, multinationals, with multiple ERPs or high billing volumes turnover, TicketBAI has meant a profound technical change when it comes to generating, recording, and reporting transactions to the Regional Treasury. In this article, we clarify when TicketBAI came into effect in Bizkaia, who it affects, who is exempt, and what the consequences are.
What is TicketBAI and why is it already vital in Bizkaia?
To begin with, TicketBAI is the invoice control system promoted by the Basque Country's regional tax authorities to prevent tax fraud and improve the traceability of economic transactions.
Therefore, TicketBAI Bizkaia is this same fiscal and tax system applied to the province. It is part of the Batuzproject, which is based on three pillars:
- TicketBAI, for invoicing control.
- LROE Bizkaia, which is the Economic Operations Register.
- Assisted tax returns.
Batuz's goal is also to to ensure that every invoice issued is recorded, digitally signed, and automatically communicated to the tax authorities, without subsequent manipulation.
TicketBAI in Bizkaia: when will it finally come into effect?
To answer the direct question of when TicketBAI Bizkaia comes into effect, if you have done business or do business with companies or administrations in Bizkaia you will know that it is already in force. However, it has only been in force for a short time.
Implementation dates
Like other systems, the implementation of TicketBAI in Bizkaia has been gradual, although the schedule is now completely finalized. We can see this in the table below:
| Date | Regulatory situation |
| 2022–2023 | Voluntary period with tax incentives. |
| 2024 | TicketBAI Bizkaia mandatory for companies. |
| January 1, 2026 | Mandatory for all other professionals and freelancers (although there are some exceptions until mid-year). |
Therefore, from 2024, TicketBAI is mandatory for all companies operating in Bizkaia, regardless of their size, sector, or turnover. So there is no longer an adaptation phase or general moratoriums for commercial companies, although there are some exceptions until mid-2026 for certain self-employed workers.
The latest of the three provinces
In fact, the entry into force of TicketBAI in Bizkaia has been slower than in Álava (between 2022 and 2023 with sectoral implementation) and Guipúzcoa (between 2021 and 2023).
Mandatory TicketBAI Bizkaia: which companies are affected?
In turn, the mandatory use of TicketBAI in Bizkaia affects:
- Companies with tax domicile in Bizkaia.
- Companies permanently established (also with registered office) in Bizkaia.
- Foreign business groups that invoice operations subject to taxation in Bizkaia.
- Companies with ongoing economic activity in the province, regardless of their sector.
Furthermore, although the regulations are cross-cutting, there are sectors where the operational impact of the entry into force of TicketBAI for Bizkaia is greater. Specifically:
- Industry and manufacturing.
- Distribution.
- Retail, especially B2B.
- Energy and utilities.
- Corporate professional services.
- Technology and SaaS companies with local billing.
In these environments, the challenge has been to to integrate TicketBAI into complex architectures without disrupting existing processes.
The requirements of the TicketBAI regulations in Bizkaia:
As for how to comply with TicketBAI in Bizkaia after it comes into force, it involves much more than just generating a QR code on the invoice. In fact, the basic requirements that you should already be complying with are:
- Using an approved billing software.
- Digitally sign each invoice with a valid certificate.
- Include the aforementioned QR code and the TBAI identifier.
- Automatically send the invoice to the Bizkaia Regional Treasury.
- Do not alter the content once you have broadcast it.
- Keep and trace all records or invoices.
In any case, you can easily meet all these requirements with the first one: approved software, such as the solutions we design at easyap.
In any case, from a financial and compliance standpoint, this means that you, as a financial manager, should have done the following:
- Audit billing systems.
- Review tax data flows.
- Align your ERP, satellite systems, and tax reporting.
LROE Bizkaia, the great forgotten (and most critical)
Another aspect that many companies have struggled to understand in this implementation has been the LROE Bizkaia (Register of Economic Operations). This is a mandatory electronic register that:
- Consolidate all invoices issued and received.
- It is automatically fed from TicketBAI.
- Replaces traditional VAT books.
The problem is that it worries (or should worry) financiers and CEOs because:
- Requires absolute consistency between invoicing, accounting, and taxation.
- Reduces the margin for ex post correction.
- Increased exposure to penalties for systematic errors.
Therefore, the LROE requires align finance, IT, and taxation as never before.
TicketBAI Bizkaia exemptions after coming into force
On the other hand, it is important to be very clear: exemptions for TicketBAI in Bizkaia after its entry into force are limited and very specific. Exemptions or special regimes may only exist for:
- Activities completely exempt from billing.
- Very specific cases regulated by the Regional Treasury.
- Certain transactions not subject.
So, having a low turnover, being a foreign company, or using an international ERP system that is not adapted will not exempt you from complying with TicketBAI in Bizkaia from now on. Let's look at some examples.
Example 1: Multinational industrial company
A German industrial company with a subsidiary in Bizkaia:
- Bill locally.
- Uses SAP as its global ERP.
- Issues thousands of invoices monthly.
Obligation: you must adapt your billing system so that every invoice issued from Bizkaia complies with TicketBAI, regardless of its overall structure.
Example 2: International SaaS company
Technology company based in the US with clients in Bizkaia:
- Recurring billing.
- Monthly subscription.
- Centralized cloud ERP.
Obligation: you must ensure that invoices issued to Bizkaia are generated using software that is adapted to TicketBAI and that they are reported automatically.
Risks of non-compliance with TicketBAI in Bizkaia
Anyone who is not already complying runs risks such as these:
- Penalties ranging from €2,000 to €80,000 per transaction, depending on the severity.
- Possible invalidity of invoices.
- Recurring tax inspections.
- Damage to reputation with the government and potential customers.
- Blocking of internal closing and reporting processes.
Why is TicketBAI a financial project and not just a tax one?
What has become clear since TicketBAI came into force in Bizkaia is that it is a financial project and not just a tax one. For CFOs and finance departments, it means:
- Redesign processes.
- Implement new internal controls.
- Rely more on data quality.
- Coordinate areas and teams, such as IT and technology providers.
In other words, we are facing a structural change in the financial function.
