GKS 2.0 Deadlines: When Does Your Hospitality Business Need to Make the Switch?

GKS 2.0 became mandatory on July 1, 2026, for new hospitality businesses subject to the registered cash register system. Existing users have a transition period. The official schedule identifies three groups, based on the date the current cash register was purchased.

New Food and Beverage Establishments Starting July 1, 2026

If you are starting a new business and are subject to the GKS requirement, you must immediately opt for GKS 2.0. Both the point-of-sale system and the tax data module must be GKS 2.0-certified.

Plan for registration, delivery, networking, and training well in advance of the opening date.

Read more about what GKS 2.0 means for a Certified point-of-sale system and the new black box for the hospitality industry.

Existing GKS users: three deadlines

  • Cash registers purchased before January 1, 2018: no later than July 1, 2027
  • Cash registers purchased from January 1, 2018, through December 31, 2021: no later than July 1, 2028
  • Cash registers purchased on or after January 1, 2022: no later than January 1, 2029

Which purchase date counts?

The Federal Public Service Finance states that, if multiple cash registers have been purchased, the date of the most recent purchase applies. The purchase date of the fiscal data module is not used to determine the transition deadline.

Why not wait until the last few months?

The migration includes point-of-sale software, FDM, hardware, payment terminals, data, registration, and training. Integrations with printers, the kitchen, Scrada, or other systems must also be revalidated.

As a deadline approaches, demand for certified hardware and installation slots may increase.

Practical Planning

  • Have the GKS obligation and deadline confirmed for tax purposes
  • Take inventory of the cash register, receipt, and current FDM
  • Verify the official certification of new components
  • Data Cleanup and Testing Service Plan
  • Test payments, tickets, adjustments, and daily closing
  • Keep records and delivery documentation

Making the right choice starts with how you operate

The deadline is a cut-off date, not an ideal time for the project. Start with an official review and plan the transition for a quiet time when your team can test and learn.
