In brief
- To receive e-invoices you need a tax number (DIČ), registration and authorisation on the Financial Administration Portal, and a contract with a Digital Postman.
- Choosing a provider on the portal does not replace the contract — until the provider registers you, you are not on the network.
- You can have only one provider for receiving; the Financial Administration expects a simple application to cost €5 to €12 a month.
- Check your registration by company ID: you must be on the network under 0245:DIČ.
From 1 January 2027 every company and business that a VAT payer invoices must be able to receive an e-invoice — even if it never issues one. Invoices arrive through a certified delivery service provider, which the Financial Administration calls a Digital Postman. Here is how to get ready.
1. Make sure you have a DIČ
On Peppol a sender finds you by your DIČ (0245:DIČ), not your IČO. If you have no DIČ, apply to the tax office for income tax registration — it issues a DIČ within 30 days of the application.
2. The Financial Administration portal and authorisation
You choose your Digital Postman for receiving invoices on the Financial Administration Portal. You need two things, and they are separate steps:
- to be registered on the portal as a user,
- to hold authorisation to represent the company you are choosing for.
A common snag: a director signs in and sees only their sole-trader business, not the company. That means they have no authorisation for the company — they request it through the portal's Personal Internet Zone or in person at the tax office.
3. Choose on the portal, then sign a contract
According to the Financial Administration, the choice on the portal is only an initial expression of interest — it makes sure the provider receives your identifiers without errors. It does not replace a contract. Until the provider contracts with you and registers you, you are not on the network. If no contract follows, you can repeat the choice with another provider at any time.
- For receiving you can have only one Digital Postman at a time — delivery has to be unambiguous.
- For sending you can use several. A provider used for sending may ask you for a verification token, which you get by making the choice on the portal.
- The Financial Administration publishes and keeps adding to the list of certified providers.
What it costs
It depends on the provider: some charge per invoice, others a monthly or annual subscription. The Financial Administration expects a simple application to cost no more than the EU average of €5 to €12 a month. A business receiving and issuing only a few dozen invoices does not need an automated system: an account in the provider's application, from which you download invoices or to which you give your accountant access, is enough.
4. Check that it works
Once registered, a sender should find you in the network's address book (the SML) under 0245:DIČ, with a provider stating that you receive Peppol BIS Billing 3.0 invoices. You do not need to be listed in the Peppol Directory — listing is optional and does not affect delivery.
If our tool shows you under a scheme other than 0245, an invoice addressed by DIČ will not reach you — ask your provider to register you under 0245:DIČ.
When something is wrong
- Your DIČ is registered with a foreign provider you never asked: contact it and ask for the registration to be cancelled. Slovak subjects belong to the Slovak central SMP. If you do not know who registered you, the Financial Administration's call centre will tell you after verification.
- You want to change provider: the switch uses a migration code issued by the old provider. According to the Financial Administration, receiving is not interrupted.
Do not leave it to December
On 23 September 2026 the network held 2,510 Slovak companies out of roughly 650,000 subjects with a DIČ that the Financial Administration publishes. Registration is not automatic — it needs authorisation on the portal and a contract with a provider, and each can take a while. Do not leave it to the last days.
