Turkey Updates e-Fatura Special Integration Guide to Version 1.14

Turkey updated the e-Fatura Special Integration Guide, adding TÜRKAK-approved ISO certificate requirements and e-Gider Pusulası codes. The update mainly affects special integrators, with indirect impact on taxpayers using their services.

The main 2026 change is the new requirement for special integration applicants to have TÜRKAK-approved ISO certificates. The update also adds codes and labels for e-Gider Pusulası in user account opening and cancellation processes.

The impact is mainly on special integrators, who must meet stronger security, business continuity, logging, disaster recovery, and testing requirements. Retailers and other taxpayers are affected indirectly, as they should ensure their e-Fatura provider is authorized and technically compliant.
