Checkout never waits
The payment is done at once. The sale is sent in the background and the customer never waits for EET.
Payky is ready for Czech EET 2.0
From 1 January 2027, Payky sends every payment it receives to EET on its own. It costs nothing, and neither does the cash register certificate from the Financial Administration.
Connecting needs a cash register certificate from DIS+, available from 1 November 2026. Until then, you can try everything with the Financial Administration's official test certificate.
Setting up Payky
You'll find everything in the app under Settings → EET.
In DIS+ on the MOJE daně portal, you set up a recording unit and generate a cash register certificate.
How to do it in DIS+Pick the .p12 file and enter its password. Payky checks the password, key, tax ID and validity right away.
The number DIS+ gave you.
Tips that belong to the business are part of the sale. When they belong to the employees, Payky leaves them out.
A verification message checks the setup, and in the sandbox you can send a test sale too. None of it is recorded.
From then on, Payky sends every payment it receives as a sale: cash, QR payments and bitcoin.
You can get your own certificate only from 1 November 2026. In the sandbox, use one of the Financial Administration's official test certificates instead and go through recording as a dry run.
What Payky takes care of
The payment is done at once. The sale is sent in the background and the customer never waits for EET.
When the network drops, Payky keeps resending the sale until EET confirms it. Anything not through within 48 hours is flagged on the payment.
Money returned is recorded as a new sale with a negative amount. Payky sends it as soon as you record the refund.
Each device is its own cash register. If one goes offline, another device of the account sends its sales after ten minutes.
Each payment shows whether EET confirmed it, with the confirmation code. Unconfirmed sales are listed together in the settings.
Three weeks before your certificate expires, Payky's settings warn you so you can renew it in time.
Deadlines
In DIS+ on the MOJE daně portal you sign up for recording, create recording units and generate a cash register certificate.
Sales recording starts. January runs as a pilot, but it is already standard recording.
Activating DIS+ can take up to 48 hours. Don't leave registration to the last minute.
Who it applies to
Every business, individual or company, that receives recorded sales has to record them. What matters is how the customer pays.
Exempt are, for example, the state and municipalities, banks and insurers, public transport and vending machines. Full list of exemptions on eet.gov.cz
Flat-rate taxpayers in the first band with income up to CZK 1 million can opt out of recording. It costs an extra CZK 1,400 a month on top of the flat tax, CZK 16,800 a year. They have to sign up by the 10th day of the tax period, and the choice holds for the whole year.
Getting ready with the tax office
Everything is done online in the Tax Information Box (DIS+) on the MOJE daně portal, from 1 November 2026.
On the MOJE daně portal, open Online finanční úřad and log in with your Citizen Identity, data box or Financial Administration credentials. Activate DIS+, which can take up to 48 hours, and choose "Chci začít evidovat" (I want to start recording).
A recording unit is your premises, fixed or mobile such as a stall, a website or app, or you yourself when you work at customers' places. The system gives it a number that can't be changed. That's what you enter in Payky.
In the Certificates (CA EET) tab, generate a cash register certificate for free and download the .p12 file with its password. The certificate is valid for one year.
What changes
Only who, where, when and how much is sent: your tax ID, recording unit, cash register, sequence number, date and time, and the total including VAT. No items and no customer data.
The Sales Recording Act doesn't require you to print or hand out a receipt. Other rules may require a receipt, for example when the customer asks for one.
Card and other cashless payments taken in person are now recorded too. So EET also applies to businesses that take no cash at all.
Without internet you keep selling. The sale has to be sent as soon as the connection is back, within 48 hours at the latest.
Self-employed individuals can claim it once, for the period in which they start recording sales. How much of it you can actually use depends on the conditions set by law.
