What is the Turkish e-Fatura mandate?
Türkiye operates one of the world’s most mature mandatory electronic invoicing regimes through the e-Fatura system, administered by the Gelir İdaresi Başkanlığı (GİB). The framework is anchored in 213 sayılı Vergi Usul Kanunu (VUK) General Communiqué No. 509 (2019, as amended). Companies meeting annual gross revenue or sectoral thresholds must issue invoices through GİB’s e-Fatura portal or via authorised integrators (Özel Entegratör), rather than paper invoices.
Threshold tiers
- e-Fatura mandate: applies above an annual revenue threshold set by GİB (updated periodically: currently TRY 3 million of gross sales revenue for 2022 and later accounting periods).
- e-Arşiv Fatura: taxpayers not yet within e-Arşiv must issue their invoices as e-Arşiv Fatura above TRY 3,000 (taxes included) in 2025 and regardless of amount from 1 January 2026; simplified-method and operating-account taxpayers keep the TRY 3,000 threshold until 31 December 2026.
- Sectoral mandates: certain sectors face lower revenue thresholds; for example, real estate and motor vehicle dealers and e-commerce businesses are in scope from TRY 500,000 of gross sales revenue for 2022 and later accounting periods.
Adjacent e-document mandates
- e-İrsaliye: electronic delivery note.
- e-Serbest Meslek Makbuzu: electronic professional services receipt.
- e-Müstahsil Makbuzu, e-Bilet and other specialised documents.
Compliance and penalties
Non-compliance triggers VUK Article 353 special irregularity penalties: per-document minimum amounts revalued every year (for 2026 by VUK General Communiqué No. 588) and risk of disregard of the document for tax purposes (KDV indirim reddi). Companies typically integrate via SAP, Logo, Mikro or specialised e-invoice service providers (Özel Entegratör).
Do: review annual revenue against current thresholds; engage an Özel Entegratör early; reconcile e-Fatura ledgers with KDV declarations monthly.
Don’t: issue a paper invoice once in-scope: GİB systems detect the gap and apply penalties automatically.
e-Fatura as systems obligation
Türkiye’s e-invoicing mandate is an architecture requirement wearing tax clothing: thresholds and sector rules pull companies into e-Fatura/e-Arşiv, integration runs through GİB-approved channels (portal, integrator, or direct), and the documents are legally the invoice: paper duplicates have no independent life. The operational legal points: archive obligations (ten-year retention in compliant formats), integrator contracts that allocate outage and error liability (an invoice not issued on time is the taxpayer’s penalty, whatever the SLA says), foreign-entity edges for cross-border billing, and ERP change-management since invoice-content errors propagate at machine speed. For SaaS billing into Türkiye, e-Fatura readiness is part of going-live, not a finance afterthought.
