Book NowTurkey’s Gelir İdaresi Başkanlığı (GİB), under its regulations governed by the Tax Procedure Law (VUK) and related communiqués and updates, has progressively rolled out a national electronic invoicing / electronic document system. The system mandates structured e‑invoicing (and e‑archive invoicing) for many taxpayers depending on turnover and sector, changing how businesses issue, report, and archive invoices across the country.
The mandate requires all identified taxpayers to issue invoices in a structured digital format (UBL‑TR XML), digitally signed, and submitted via the GİB‑registered/accredited system. Any invoice not issued in the required structured format and transmitted through the official channel is not considered valid under the regulation.
E‑invoicing in Turkey is designed to improve transparency, reduce tax evasion, and automate record‑keeping for both businesses and the tax authority. This blog explains the requirements of the system, who must comply, the technical process, benefits, and how providers like Flick Network can help companies comply smoothly with the law.
E‑invoicing in Turkey (commonly via systems known as e‑Fatura and e‑Arşiv Fatura) refers to issuing, validating, and storing invoices electronically in a structured data format (UBL‑TR XML) via the official GİB portal (or certified service providers), rather than relying on paper‑based invoices or unstructured digital copies (like scanned PDFs).
Each invoice must be digitally signed using a fiscal seal or qualified electronic signature, ensuring the authenticity and integrity of the document.
Invoices issued via e‑Fatura or e‑Arşiv must pass through the GİB platform for validation and clearance (for e‑Fatura) or be reported (for e‑Arşiv), rather than being issued and kept solely by the seller.
Invoices that are merely scanned copies or photos of paper invoices do not qualify as electronic invoices under the regulation. Once issued in the required structured format, and submitted through the appropriate system, the business retains the electronic record; the tax authority and both supplier and buyer can access and audit the transactions.
The process eliminates manual paperwork, ensures data accuracy, and provides traceability across business transactions in Turkey.
2014: e‑Fatura (electronic invoicing) became available; businesses could start issuing electronic invoices alongside paper invoices.
As of 1 July 2023: Companies whose gross annual turnover (from 2022) exceeded TRY 3 million became subject to mandatory e‑invoicing for B2B transactions.
For certain sectors; such as e‑commerce, real estate, motor vehicles, construction, and professional intermediaries – the threshold for mandatory e‑invoicing is lower: gross sales revenue exceeding TRY 500,000.
September 1, 2023: All e‑invoices (e‑Fatura and e‑Arşiv) became required to include a QR code for verification.
2025: The technical guidelines for e‑Fatura (e‑invoice) have been updated by GİB, including changes in validation rules and XML schema, taking effect with updates through 2025.
The e‑invoicing mandate in Turkey applies to the following taxpayers:
Businesses with an annual gross sales revenue exceeding TRY 3 million (in the relevant fiscal period) for B2B transactions must use e‑Fatura.
Businesses operating in certain sectors; e‑commerce, real estate, motor vehicles, construction, or professional intermediaries - with gross sales exceeding TRY 500,000 must also comply.
Suppliers issuing invoices to public entities (B2G) are generally required to issue invoices electronically, but must comply according to GİB registration and reporting requirements; turnover may still be relevant for some cases.
For businesses not registered under e‑Fatura; or for B2C transactions (or B2B where buyer is not registered) - if invoice value exceeds the current threshold of TRY 3,000 for unregistered buyers (as of 2025), they must issue an e‑Arşiv invoice instead of a paper invoice. This threshold is expected to be eliminated in the coming years.
Here are the key technical requirements and process points under the mandate:
Invoice Format: Invoices must be issued in UBL‑TR XML format, which is the Turkish adaptation of the UBL standard.
Digital Signature / Electronic Seal: Each invoice must be digitally signed; using a fiscal seal (mali mühür) or qualified electronic signature - to ensure authenticity and integrity.
Invoice Transmission / Submission:
For B2B (registered both sides) and B2G – use e‑Fatura: the invoice is submitted to GİB for validation and clearance; once cleared, GİB forwards it to the buyer.
For B2C (or B2B when buyer is not registered) – use e‑Arşiv: invoice is generated, digitally signed, sent to the buyer, and the seller reports the invoice data promptly (typically by end of day) to GİB.
Archiving and Record‑Keeping: All invoices - e‑Fatura and e‑Arşiv - shall be stored digitally (in XML/structured format) and can be archived instead of paper copies. Invoices have to be digitally archived for audit readiness.
Data Integrity and Compliance: The system assures integrity, structured format, digital signatures, and use of QR codes since 2023 for verification.
E‑invoicing in Turkey provides businesses and the tax authority with several benefits, both regulatory and operational:
Efficiency: The system automates the invoicing, delivery, and reporting processes, therefore minimizing manual work for accounting teams.
Accuracy: With structured data and digital signatures, invoices become uniform in their accuracy. This reduces human error and enhances audit readiness.
Compliance: Real‑time or near‑real‑time reporting to GİB increases the level of transparency by allowing the tax authority to monitor the transactions quickly and, thus, helps deter tax evasion.
Cost Savings: Reduces need for printing, physical storage, postage or shipping, thus cutting costs operationally and saving time.
Traceability: Digital invoices, QR code, signature, and archive make any transaction traceable and verifiable.
Consistency: standard formats - UBL‑TR XML- and a central platform provide consistency among the invoices, buyers, sellers, and the tax authority.
Non-compliance with e‑invoicing requirements in Turkey may involve serious risks:
Invalid invoices: The invoices that were issued without an e‑Fatura/e‑Arşiv and digital signature/structure might be considered invalid by the law.
Penalties: Both the issuer and the receiver will be penalized. If one does not issue or receive an invoice that is compliant, or does not meet formal requirements, they will be fined; the amounts vary upon the case and year.
Business Disruption: Non‑compliance may lead to complications in bookkeeping, audits, inability to prove legitimate transactions, and legal scrutiny.
Increased Audit Risk: Without proper electronic records, businesses may face fines or back‑tax assessments in audits.
Here are steps businesses should take now to prepare:
Assess Your Systems: Check whether your accounting, billing, or ERP/POS systems support UBL‑TR XML invoice generation and can integrate with the GİB platform.
Register on the GİB Portal: Ensure your company (via its tax identity / VKN) is registered with GİB for e‑Fatura or e‑Arşiv, depending on your business type and turnover.
Digital Certification: Obtain a fiscal seal or qualified electronic signature (as required) to digitally sign invoices.
Choose a Solution Provider: Partner with a provider with a compliant solution; for example Flick Network - for integration, validation, secure transmission, and archiving support.
Integrate & Test: Connect your billing/ERP to the GİB‑registered system, send sample invoices, validate data mapping, ensure all header fields, tax codes, profile IDs comply with the updated regulations.
Staff Training: Train your finance and accounting team on how to issue structured e‑invoices, report data, store records, and manage your new invoicing workflow.

Turkey’s structured e‑invoicing regime under GİB represents a major shift in digitising tax compliance and business invoicing operations. From the turnover thresholds for B2B companies to sector‑specific mandates (e‑commerce, real estate, construction, etc.), public‑sector invoicing obligations, and B2C invoice reporting via e‑Arşiv, the mandate aims for transparent, traceable, and efficient invoicing across the economy.
With updated technical validation rules, inclusion of QR codes, digital signatures, and mandatory archival, the law tightens compliance while enabling operational efficiencies.
By preparing early; registering systems, integrating billing/ERP software, obtaining digital certificates, training teams and archiving records properly - a company will streamline operations, reduce errors and remain fully compliant with Turkish e‑invoicing law. Solutions like Flick Network help make the process smoother by managing generation, transmission, archiving and compliance end‑to-end. Early adoption helps minimize disruption, avoid financial penalties and benefit from a system of efficient, transparent and fully digital invoicing across Turkey.
What is the GİB e‑Invoicing system in Turkey?
It is the national platform managed by Gelir İdaresi Başkanlığı where structured invoice data (e‑Fatura or e‑Arşiv) must be submitted or reported to enable electronic invoicing and sales/transaction reporting.
Who must comply with the e‑invoicing mandate in Turkey?
Businesses with annual gross turnover above TRY 3 million, or certain sector‑specific businesses (e‑commerce, real estate, motor vehicles, construction, professional intermediaries) with sales above TRY 500,000; suppliers to public entities (subject to registration rules); and sellers issuing invoices to non‑registered buyers/consumers above the current threshold of TRY 3,000 for e‑Arşiv.
What happens if a business issues a scanned copy of a paper invoice in Turkey?
Such a scanned copy does not qualify as a valid electronic invoice under the regulation. Only system‑generated structured invoices, digitally signed and submitted through GİB (or certified provider) count as valid.
