What is the Czech TIN Number (DIČ)?


The Czech TIN (Tax Identification Number), also known as DIČ (daňové identifikační číslo), is a unique number assigned to taxpayers in the Czech Republic. Mostly, TIN number is usually their "rodné číslo" (birth number). But having a birth number does not automatically make it your TIN; it must be officially assigned and registered by the Czech tax office under your rodné číslo.


For foreigners who don't have a Czech birth number (rodné číslo), the Czech tax office generates a unique TIN number. Once assigned, this number stays the same for you, even if you stop earning income or no longer declare taxes.

How to Get a Czech TIN Number?

A Czech TIN number is assigned by the tax office, typically during your first income declaration—this could be your first salary, property tax, or trade license registration.

It’s important to note that the TIN number is not just for businesses. Currently or previously employed people, as well as anyone who has filed a tax return have a TIN number

Haven’t declared any taxes yet? If you've never been employed or registered as self-employed, and haven't declared taxes before, you can apply for a TIN number voluntarily. To get your Czech TIN number, visit your local tax office, where you will receive a TIN number certificate upon registration.

Why Do You Need a TIN (DIČ) Number?

A TIN number is often required by banks to confirm your tax residency. Without a TIN number, you cannot file income tax reports or obtain tax residency certificates in the Czech Republic.


Issues with Bank Apps and TIN Validation

Some international banks or apps may not recognize the TIN number generated by the Czech tax office for foreigners. These apps might only expect a rodné číslo (Czech birth number), which can lead to confusion. If your unique TIN number is rejected, it doesn’t mean it’s invalid—the app simply has wrong validation process.


To avoid such issues, EU citizens in the Czech Republic should consider applying for Czech temporary residency and obtaining a rodné číslo( Czech birth number)
