Introduction of TSE from 2026: What Taxi and Rental Car Companies Need to Know Now
As of January 1, 2026, the Technical Security Device (TSE) will be mandatory nationwide for all taxi and rental car companies. This marks the end of the transition period for businesses that have been using older recording systems like INSIKA. From this point on, only electronic recording systems with certified TSE will be permissible.
Purpose and Requirements of the TSE
The TSE serves to provide seamless and tamper-proof documentation of all tax-relevant business transactions in the vehicle. This includes, in particular, the time, type of ride, amount, and vehicle registration number. The requirements are based on the Cash Register Security Ordinance (KassenSichV) and § 146a of the German Tax Code. The TSE has been legally required in retail and gastronomy since 2020.
Transitional Regulation Until End of 2025
Up to and including December 31, 2025, existing systems without TSE – such as those based on the INSIKA technology – may continue to be used. However, new taximeters or odometers may only be operated with certified TSE. The use of non-compliant systems will be considered a tax regulatory offense from 2026 onwards and may result in fines.
Retrofit and Technical Implementation
Both hardware-based and cloud-based solutions are available for retrofitting. The costs for hardware-supported TSE modules start at around 500 euros per vehicle. Cloud-based variants incur ongoing monthly fees. Both solutions can be claimed as operating expenses for tax purposes.
Regardless of the chosen solution, it must be checked before acquisition whether the system is certified by the Federal Office for Information Security (BSI). Both retrofit kits and new devices with TSE capabilities from the factory must meet these requirements.
