Czechia TIN number guide
Daňové identifikační číslo (DIČ)
Daňové identifikační číslo contains 9 to 10 digits. It also sometimes referred to as Personal Number. The DIČ is issued by the Czech Financial Administration (Finanční správa) and is listed in the worldwide directory of VAT and tax ID names.
For businesses registered for VAT, the DIČ is prefixed with "CZ" (e.g., CZ12345678) and functions as the Czech VAT number, verifiable through the EU VIES system. To verify a Czech DIČ online, use the Czech Financial Administration's registry or the EU VIES portal.
Format 999999/999 or 999999/9999

Frequently Asked Questions
Why does having a Czech DIČ not mean I am a VAT payer, and what happens if I use the wrong number on EU invoices?
A DIČ (Daňové identifikační číslo) is assigned to every taxpayer in the Czech Republic — including sole traders paying only income tax — but it does not prove VAT registration. You become a VAT payer only when your turnover exceeds CZK 2,000,000 per calendar year (or CZK 2,536,500 for immediate registration). If you quote a DIČ on cross-border EU invoices without being an active VAT payer, your number will fail VIES validation and your customer cannot zero-rate the supply. To verify VAT status specifically, check the Czech Financial Administration registry at adisspr.mfcr.cz or the EU VIES portal. The DIČ with the "CZ" prefix functions as a VAT number only for registered VAT payers. (Czech Financial Administration)
What tax number does a foreigner without a Czech birth number (rodné číslo) receive, and why do some systems reject it?
Foreigners who lack a Czech rodné číslo (birth number) receive a special tax identifier called a VČP number (vlastní číslo plátce), which starts with "710" or "720" depending on the registration method. Because most Czech validation systems expect either an 8-digit IČO (for companies) or a 9-10 digit rodné číslo, VČP numbers are sometimes rejected by banking apps, invoicing software, and third-party portals that hard-code the standard format. If your VČP-based DIČ is rejected, the number is not invalid — the system simply lacks support for non-standard formats. Contact the Czech Financial Administration (Finanční správa) to confirm your number, and request the rejecting party update their validation logic.
What are the penalties for late filing of the Czech VAT Control Statement (kontrolní hlášení)?
Unlike standard Czech tax filings, the VAT Control Statement (kontrolní hlášení) has zero grace period — penalties are automatic from day one. Late submission without a summons incurs a CZK 1,000 fine. If the tax authority issues a summons and you respond within the deadline, the fine rises to CZK 10,000 (CZK 5,000 for sole traders). Ignoring the summons entirely triggers fines up to CZK 50,000 (CZK 25,000 for sole traders). Since 2023, first-time violations in a calendar year may be waived at the authority's discretion. The legal basis is Section 101j of the Czech VAT Act (Zákon č. 235/2004 Sb.). (Czech Financial Administration)
What happens if my Czech supplier is on the unreliable VAT payer (nespolehlivý plátce) list?
If you purchase from a supplier designated as an unreliable VAT payer (nespolehlivý plátce), you can be held jointly liable for their unpaid VAT under the Czech VAT Act. This applies when the supplier's unreliable status was publicly listed at the date of supply. Additionally, paying to a bank account not registered with the tax authority creates the same liability risk. To protect yourself, check every supplier before transacting using the Czech Financial Administration registry at adisspr.mfcr.cz, which allows searching by DIČ and filtering by reliability status. Over 10,000 entities have been designated unreliable, approximately 2% of all Czech VAT payers. (Czech Financial Administration)
What new obligations apply to foreign companies registered for Czech VAT since January 2025?
Since January 1, 2025, an amendment to the Czech VAT Act requires all foreign VAT-registered persons without a Czech data box (datová schránka) to appoint an authorized representative for service of documents and to provide an email address. Entities already registered before January 1, 2025 had until February 28, 2025 to comply. Failure to appoint a representative results in a fine of CZK 1,000 per day of delay. Applications must be filed through the Financial Office for the Capital of Prague, in Czech, with all supporting documents requiring certified Czech translations. Most non-resident businesses file monthly VAT returns by the 25th of the following month. See our guide to worldwide VAT registration thresholds for Czech-specific thresholds.
