Why did the Financial Administration assign me a tax identification number?
Short answer
The ex officio registration and assignment of a tax identification number are connected with preparing identifiers for electronic-invoice receipt. VAT payers use a VAT identification number, while non-taxable persons required to receive e-invoice need a tax identification number. The Financial Administration stated that it would send decisions to approximately 58,000 existing non-taxable persons.
Non-taxable person identifier
Replaces VAT identification number where the entity is not the payer.
Existing non-taxable persons
Gradual automatic registration in the coming months.
For income tax
Non-business-driven entities need not address new returns.
Addressability in Peppol
tax identification number allows for unambiguous delivery e-invoice.
Detailed explanation
For taxpayers who are not established or incorporated for business purposes (such as non-profit organisations, civic associations or other non-taxable legal entities), the allocation of a VAT number does not entail any new obligations regarding the filing of income tax returns or any other related administrative tasks. It is purely a technical measure to provide a unique identifier that these entities need in order to be correctly addressed as recipients of electronic invoices within the Peppol network.
As set out in the Act
The use of the VAT number as an identifier for non-taxable persons in the electronic invoicing system is based on the Peppol Authority Specific Requirements (PASR) for the Slovak Republic and on the amendment to the obligation to accept electronic invoices under Act No. 385/2025 Coll., amending Act No. 222/2004 Coll. on VAT.
Practical examples
- The civic association will receive a decision on its registration and the allocation of a VAT number without having to apply for it itself.
- A foundation funded by donations will use the assigned VAT number solely for the purpose of receiving e-invoices, not for submitting new tax returns.
- A newly established non-profit organisation will be issued with a VAT number automatically upon its incorporation.
Most common mistakes
- “The allocation of a VAT number means that the organisation must now file an income tax return.” For entities not established for business purposes, this does not entail any new income tax obligations.
- “The tax identification number replaces the VAT registration number even for taxable persons.” VAT payers continue to use their VAT registration number as their identifier; the tax identification number applies to non-taxable persons.
- “The allocation of a tax identification number is a mistake or an administrative error.” This is a deliberate, planned move by the Financial Administration linked to the introduction of e-invoicing.
Conclusion
The assigned number serves as a technical identifier for receiving e-invoice and does not by itself create new income-tax obligations.
