Czech: Getting Ready for EET 2.0 Electronic Registration

To record sales, check technical equipment compatible with the EET 2.0 system, choosing the best device for your business. Sign up through DIS+ on the MY TAXES portal. Register your units and generate a cash certificate via the CA EET portal to ensure secure data transmission. A registration unit defines where sales occur, including physical establishments and online platforms. Legislative changes may apply.

If the retailer is required to record sales, follow these steps:

Check the technical equipment

The EET 2.0 system allows recording sales on common devices (mobile phone, tablet, laptop, desktop PC, or existing cash register). For entrepreneurs with very few transactions, a free responsive web application will be provided by the Financial Administration.

The law does not prescribe specific devices — the seller should choose the solution that best suits his/her business. If there is already a cash registers, contact the supplier to confirm they will update them to EET 2.0.

Sign up for electronic sales records via DIS+

Log in to the MY TAXES portal (www.mojedane.cz) through the Online Tax Office using:

• citizen identity (bank ID, eCitizen, My ID, eGovernment Mobile Key, etc.),
• data box, or
• access data provided by the Financial Administration.
• From DIS+, access the Electronic Sales Register.

Register the registration units and generate a certificate

In DIS+, register the registration unit(s). the site will then redirect the retailer to the CA EET portal (certification authority), where he/she can generate the certificate(s) free of charge. Save and install the certificate in the cash register (or application) according to the supplier’s instructions. The cash register certificate will automatically sign data messages sent from the cash register to the EET 2.0 system.

Purpose of the sales record certificate

The “cash certificate” electronically signs sales data messages and ensures their security. It guarantees that the message was sent by the specific taxpayer and was not altered during transmission. Certificates can be automatically renewed by the cash register (if supported). If needed, the certificate can be invalidated on the CA EET portal via DIS+ (e.g. in case of loss or misuse).

What is a registration unit?

A registration unit defines the place where goods are sold or services provided. It includes:

• An establishment under the Trade Licensing Act (including mobile stands), or its equivalent for non-trade activities;
• A website, part of a website, or application offering goods/services;
• The taxpayer themselves, if business activities are carried out outside any establishment or online platform (e.g. Crafts performed at the customer’s premises). In such cases, the registration unit is the taxpayer’s registered office.

 

The information is based on the draft Act on Sales Records as of 5 March 2026. The legislative process is not yet complete, so changes may occur.
