2026 Guide to Mandatory Transition to E-Invoice and E-Ledger

As of July 1, 2026, taxpayers meeting certain turnover and operational criteria will become subject to the mandatory transition to the e-Invoice, the associated e-Archive Invoice, and, where applicable, the e-Waybill systems.

Within the framework of the electronic document applications established by the Turkish Revenue Administration (TRA), businesses whose gross sales revenue for the 2025 fiscal period exceeds the specified thresholds, as well as those falling within the mandatory scope regardless of turnover, are required to complete their e-Document transition procedures within the prescribed period.

Who Is Required to Transition to e-Invoice?

The principal taxpayer groups subject to the mandatory transition in 2026 are as follows:

Scope of Transition and Revenue Thresholds
General Turnover Threshold: Taxpayers with a gross sales revenue of TRY 3 million or above in the 2025 fiscal year.
E-Commerce Activities: Taxpayers engaged in online sales of goods or services, facilitating such sales, or publishing online advertisements, with a 2025 fiscal year revenue of TRY 500 thousand or above.
Real Estate and Motor Vehicle Sectors: Taxpayers engaged in construction, purchase, sale, or rental activities with a 2025 fiscal year revenue of TRY 500 thousand or above.
Mandatory e-Waybill Transition: e-Invoice taxpayers with a gross sales revenue of TRY 10 million or above in the 2025 fiscal year.
Entities Covered Regardless of Turnover Thresholds: Taxpayers specified in the relevant legislation, primarily hotels and accommodation businesses licensed by the Ministry of Culture and Tourism, EMRA-licensed fuel stations, charging network operators, and fruit and vegetable wholesalers subject to the market registration system.
⚠️ Critical Warning (Revenue Calculation): When calculating gross sales revenue, not only primary operating revenues but also extraordinary revenues, such as the sale of vehicles, fixed assets, or real estate during the year, may be taken into consideration.

Timeline and Integration Process

e-Invoice / e-Waybill: July 1, 2026
e-Ledger Effective Date: January 1, 2027

Taxpayers falling within the scope of the e-Invoice system as of July 1, 2026 are also required to transition to the e-Ledger system as of January 1, 2027, in accordance with the applicable regulations. To avoid any operational disruptions, it is essential to complete applications for an e-signature/financial seal and private integrator services well in advance.

Action Items for Transition

  • Verify whether the business falls within the scope of the e-Document obligation based on its sector and turnover criteria.
  • Apply for an e-signature or, for corporate entities, ensure that a valid Financial Seal application is completed in a timely manner.
  • Complete the TRA e-Invoice and e-Ledger application procedures through the relevant system.
  • Select either the TRA Portal or a Private Integrator, taking into account invoice volume and archiving requirements.
  • Test the compatibility of existing accounting, ERP, and commercial software integrations.

Consequences of Non-Compliance

Taxpayers who are subject to the mandatory transition but fail to adopt the e-Invoice, e-Waybill, or e-Ledger systems within the prescribed period may face special irregularity penalties and other administrative sanctions under the Tax Procedure Law. Furthermore, paper-based documents issued during this period may create risks regarding document compliance, unjustified tax deductions, and tax audits.
