Turkey's e-Invoice (e-Fatura) system keeps expanding, and 2026 brings both a turnover-based deadline for mid-sized businesses and a change that affects even companies who are not required to register at all.
Who has to register — and by when
Businesses whose gross sales revenue reached roughly ₺3 million (about €55,600) or more in 2025 are required to enter the e-Invoice and e-Archive Invoice systems by July 1, 2026. If your 2025 turnover crossed that line, this is a hard compliance deadline, not a recommendation.
A lower bar for certain sectors
A reduced threshold of ₺500,000 (about €9,300) applies specifically to e-commerce businesses and companies involved in real estate or motor vehicle transactions. If your business falls into one of these categories, check your 2025 turnover against the lower figure rather than the general ₺3 million line.
The change that affects everyone else
Separately, as of January 1, 2026, businesses that are not registered for e-Invoice must now issue all documents electronically as e-Archive Invoices, regardless of the transaction amount. This removes the previous ₺3,000 threshold below which paper documentation was still acceptable — in practice, paper invoicing below that line is no longer an option for most businesses.
What to do next
- Check your 2025 gross sales revenue against the applicable threshold for your sector.
- If you cross the line, confirm your registration is completed well before July 1, 2026 — integration with an e-Invoice provider takes time.
- If you're below the threshold, make sure your invoicing process already issues e-Archive documents for every transaction, not just larger ones.
