Country deep dive
Turkey's e-invoicing framework is the most mature in this tracker outside South Korea: e-Fatura became mandatory for larger taxpayers on 1 April 2014, building on e-Transformation groundwork the Revenue Administration (GİB) had been laying since 2012. e-Defter (electronic ledgers) followed in 2015, e-İrsaliye (electronic waybills) in 2023, and the mandate continues to tighten in 2026 with a lower general threshold and the removal of e-Arşiv's monetary floor entirely.
From 1 April 2014, Turkey's Revenue Administration (Gelir İdaresi Başkanlığı, GİB) made e-Fatura mandatory for companies with turnover exceeding TRY 5 million, alongside several sectors required regardless of size -- energy companies, fruit and vegetable wholesalers, online marketplaces and service providers, and importers. e-Fatura works as a clearance model: the seller submits a UBL-TR structured, digitally-signed invoice to GİB's central platform, which validates it and distributes the cleared invoice to the registered buyer -- the seller and buyer never exchange the document directly. This built on e-Transformation groundwork GİB had been laying since 2012.
From 2015, e-Defter -- electronic general ledgers and journals, submitted to GİB in a standard XBRL-based format -- became mandatory for every e-Fatura user, as well as companies subject to independent audit under Turkish Commercial Code thresholds. This is a bookkeeping duty layered on top of e-Fatura, not a change to the invoicing mandate's own scope.
From 1 July 2023, e-İrsaliye -- Turkey's electronic dispatch note/waybill accompanying the physical movement of goods -- became mandatory for taxpayers with revenue exceeding TRY 10 million, with voluntary adoption open to everyone else. e-İrsaliye documents the goods movement itself rather than the sale, so it sits alongside e-Fatura rather than replacing any part of it -- a business can be fully e-Fatura compliant and still need to onboard e-İrsaliye separately once it crosses this threshold.
From 1 January 2026, GİB removed the previous monetary floor on mandatory e-Arşiv issuance entirely -- any invoice to a non-e-Fatura-registered recipient must now be issued electronically as an e-Arşiv invoice regardless of its value, closing what had been a real gap for small transactions. Alongside this, the 2026 e-Fatura turnover threshold based on 2025 revenue is TRY 3 million generally, with a lower TRY 500,000 threshold applying to e-commerce businesses, and real-estate, motor-vehicle, and licensed-accommodation transactions. Registration for businesses crossing either threshold on 2025 revenue is due by 1 July 2026.
Invoices are authored as structured XML in UBL-TR format and digitally signed. Which of Turkey's two parallel e-document systems applies — e-Fatura or e-Arşiv — depends on whether the recipient is itself registered for e-Fatura, not on the seller's own choice.
Every invoice is the same underlying XML format regardless of route — e-Fatura and e-Arşiv differ in who the recipient is and how GİB sees the data, not in the document's own structure.
e-Fatura and e-İrsaliye registration are tracked against two different thresholds — crossing one doesn't automatically mean you've crossed the other.
Ten years' retention lines up with Turkey's general Tax Procedure Law bookkeeping duty, not a rule unique to e-invoicing.
Turkey's mandate is revenue-threshold based rather than universal, but the thresholds have fallen steadily since 2014 and several sectors are in scope regardless of size.
The e-Fatura threshold has fallen from TRY 5 million at launch to as low as TRY 500,000 for specific sectors by 2026 — a steady tightening rather than a single cutover, similar in shape to South Korea's own threshold history.
Between e-Fatura and e-Arşiv, essentially every domestic sale is covered electronically in some form — the open question for a given transaction is which of the two systems applies, not whether either does.
When both parties are registered e-Fatura users, an invoice follows this sequence:
The seller and buyer never exchange the invoice directly — GİB sits in the middle of every e-Fatura, a genuine clearance model, the same shape as Jordan and Israel elsewhere in this tracker, though centralized through a single government platform rather than a decentralized exchange.
When the recipient isn't registered for e-Fatura — most consumers, and many smaller businesses — the invoice instead follows this sequence:
This is the flow most similar to South Korea's post-issuance model elsewhere in this tracker — the invoice is valid on delivery, and reporting to GİB is a parallel duty, not a precondition for validity. Since January 2026 there's no minimum invoice value below which e-Arşiv can revert to paper.
Getting compliant means checking your turnover against the current e-Fatura and e-İrsaliye thresholds, confirming every invoice below those thresholds is still issued as an e-Arşiv invoice, and choosing an access route — GİB's own portal, a private integrator (özel entegratör), or a direct in-house integration.
Compare your 2025 revenue to the TRY 3 million general threshold, or the TRY 500,000 threshold if you're in e-commerce, real estate, motor vehicles, or licensed accommodation — and register for e-Fatura by 1 July 2026 if you cross it.
Since January 2026 there's no minimum value below which a paper invoice is acceptable for a non-e-Fatura-registered recipient — confirm your invoicing system issues e-Arşiv electronically for every such sale, not just larger ones.
If your turnover exceeds TRY 10 million and you dispatch physical goods, confirm e-İrsaliye (e-Waybill) issuance is integrated alongside your invoicing — it's tracked against its own threshold, not the e-Fatura one.
Decide between GİB's own free e-Belge portal (suited to lower invoice volumes), a private integrator (özel entegratör) offering additional tooling, or a direct in-house integration for higher-volume issuers.
Every e-Fatura user, and any company subject to independent audit under Turkish Commercial Code thresholds, must also file e-Defter (electronic ledgers) — confirm this is integrated alongside your invoicing, not treated as a separate, optional step.
e-Fatura, e-Arşiv, e-Defter, and e-İrsaliye records all fall under the Tax Procedure Law's general 10-year retention duty — keep the original signed electronic files, not just PDF renderings.
Turkey enforces e-invoicing compliance through the Tax Procedure Law's (Vergi Usul Kanunu) special irregularity fines, calculated as a percentage of the invoice value with an inflation-indexed minimum — applied to both the issuer and, unusually among this tracker's countries, the recipient who accepts a non-compliant invoice.
