Türkiye's e-invoice mandate is expanding: what SMEs should expect in 2026

Türkiye's e-transformation programme keeps accelerating. By the end of 2025 roughly 1.9 million taxpayers were registered for e-Fatura; with the new revenue threshold taking effect in July 2026, hundreds of thousands more businesses are expected to fall under the mandate. According to the announced schedule, companies with gross sales above 3 million TRY must now issue e-invoices — it is no longer optional.

Who is covered?

• General threshold: taxpayers with gross sales revenue of 3 million TRY or more
• Lower special thresholds for sellers on e-commerce and intermediary platforms
• Some sectors (real estate, motor vehicle trade and others) are covered regardless of revenue
• Always confirm current thresholds and exemptions with the Revenue Administration (GİB) and your accountant

Three practical preparation steps

• Choose your integrator: the GİB portal can be enough for small volumes; for growing businesses, private integrators such as Nilvera or İZİBİZ are the standard route
• Connect your accounting/ERP: retyping invoice data into your books wipes out the gains of going digital
• Fix the process feeding the invoice: if orders, delivery notes and account data live in scattered spreadsheets, e-invoicing alone won't bring order

Turn the obligation into an opportunity

The overlooked side of e-invoicing: your sales data is now produced in a structured, digital, real-time form. That data doesn't have to flow only to the tax office — connected properly, it is ready-made raw material for revenue, collection and customer reports. Without replacing your integrator or accounting software, a portal layer built on top can turn it into reports in seconds. Mandatory digitalisation is the perfect starting point for bringing your processes into order.
