GKS 2.0 Mandatory for Hospitality Businesses from July 1, 2026

• GKS 2.0 (the new registered cash register system) becomes mandatory for horeca businesses starting July 1, 2026.
• New horeca businesses must use GKS 2.0 immediately from that date.
• Existing businesses get a transition period based on the purchase date of their current cash register: before Jan 1, 2018 → by July 1, 2027; Jan 1, 2018–Dec 31, 2021 → by July 1, 2028; from Jan 1, 2022 → by Jan 1, 2029.
• Both the cash register and the fiscal data module (FDM/“black box”) must be certified as GKS 2.0.
• Businesses can check their deadline via the GKS e-service and are advised to contact their supplier early to ensure a smooth transition.
