How can contact details used when selecting a delivery-service provider be updated?
Short answer
The VAT Act does not prescribe the technical procedure for changing the email address or telephone number entered when selecting a provider. These are operational contact details, but the available legal and methodological materials do not establish whether the change is made directly in the Slovak Financial Administration portal or through the selected provider. Verify the current procedure in the portal or with the provider rather than relying on an assumed workflow.
Change should be possible
Common practice for electronic communication portals with FS SR.
It is not in the law
This is about the functionality of the portal, not about legal regulation.
Verify directly on portal
Or at the chosen delivery-service provider.
Change of employee or company e-mail
A common situation requiring a contact update.
Detailed explanation
On standard electronic communication portals with the Slovak Financial Administration, it is standard practice that contact details associated with a taxpayer can be updated in the event of a change (for example, a change to the company’s email address or that of the responsible person), as otherwise they would become inoperative in the long term whenever an employee or company email address changes. However, as we do not have this specific point supported by a clearly citable statement from the Slovak Financial Administration or by the text of the law, I recommend that, if changes are required, you contact the Slovak Financial Administration’s portal directly (for example, via a general enquiry or the helpline), or the chosen delivery-service provider, who may have their own process for updating contact details within their system.
As set out in the Act
The selection of a certified delivery-service provider via the Slovak Financial Administration portal is governed by Section 76a of Act No. 222/2004 Coll. on VAT, as amended by Act No. 385/2025 Coll. The specific technical procedure for managing and changing contact details within this portal is not part of the text of the Act; it is a feature of the portal.
Practical examples
- A company has changed the person responsible for communicating with the digital post office and needs to update their contact email address.
- When changing a telephone number, the company contacts the Slovak Financial Administration portal or its service provider regarding the amendment of the details.
- Before making any major changes to its team, the company should check in advance how contact details can be updated.
Most common mistakes
- “The contact details provided when selecting a postman are set in stone.” These are standard contact details, which should normally be changeable; however, we recommend checking the exact procedure directly.
- “Changes to contact details are governed by the VAT Act.” This refers to a feature of the Slovak Financial Administration’s portal, not a legal provision.
- “Changing contact details requires the provider to register from scratch.” This is likely to be a simple update of the details, not a repeat of the entire provider selection process — however, the specific procedure needs to be verified.
Conclusion
The law does not define the update procedure; confirm the current portal or provider process before changing the contact details.
Legal basis
- Act No. 222/2004 Coll. on VAT, Section 76a (as amended by Act No. 385/2025 Coll.)
