# When is e-Fatura (e-invoice) mandatory in Turkey and how does it work?

**Quick answer:** E-Fatura is mandatory for Turkish businesses with annual gross turnover above TRY 3,000,000. It is also mandatory for all importers, exporters, e-commerce operators, banks, and regulated financial entities regardless of turnover. Once mandatory, all B2B invoices to e-Fatura registered counterparties must be issued through the GIB system or a licensed e-transformation provider. Paper invoices are legally invalid and carry a 10% penalty.

## Detailed explanation

Turkey's e-invoice mandate (e-Fatura zorunluluğu) is one of the most comprehensive in the world and has fundamentally changed how Turkish businesses issue and receive invoices. Understanding the rules prevents costly compliance failures.

**The threshold: TRY 3,000,000**
Businesses whose gross annual turnover (including KDV) exceeds TRY 3,000,000 in any calendar year must transition to e-Fatura. The transition takes effect on 1 July of the year following the year of crossing the threshold. For example: a company crossing TRY 3,000,000 in 2024 must be live on e-Fatura by 1 July 2025.

Note: the TRY 3,000,000 threshold has been the trigger point for several years but the GIB adjusts thresholds via communique. Always verify the current threshold on gib.gov.tr before year-end.

**Mandatory for certain sectors regardless of turnover**
Regardless of revenue, e-Fatura is mandatory from the first transaction for:
- All import and export transactions (e-Fatura or e-Fatura integrated with Customs declarations)
- E-commerce operators and marketplace platforms
- Banks, insurance companies, and financial intermediaries
- Pharmaceuticals distribution companies
- Organised industrial zone operators

**What e-Fatura means in practice**
When you are on e-Fatura:
1. You must issue every B2B invoice to another e-Fatura registered company through the GIB system, not via email, PDF, or paper
2. Invoices to non-e-Fatura entities (individuals, small businesses below threshold) are issued as e-Arsiv
3. All invoices above TRY 30,000 to consumers must be e-Arsiv (not paper)
4. You must simultaneously activate e-Defter (electronic accounting books): this is mandatory alongside e-Fatura

**How to check if a customer is on e-Fatura**
The GIB maintains a publicly accessible register of e-Fatura registered taxpayers. Before issuing any invoice, search the customer's VKN (tax ID) on www.efatura.gov.tr to determine whether to issue e-Fatura or e-Arsiv.

**How to issue e-Fatura: two options**

1. GIB Portal (free): Log into the official GIB e-Fatura Portal, enter invoice details manually, and submit. The recipient's account is instantly notified. Suitable for low-volume invoicing (under 50-100 per month). No cost, but manual.

2. Licensed e-dönüsüm service provider (paid): Over 100 GIB-licenced companies provide software integration for e-Fatura. They connect to your accounting system (ERP, billing software) and automatically generate, send, and archive invoices. Annual fees: TRY 2,000-10,000 depending on volume and provider. Suitable for any business issuing more than a handful of invoices per month.

**The two e-invoice scenarios (Senaryo)**
E-Fatura operates under two processing scenarios:
- Temel Senaryo (Basic): standard B2B invoicing: recipient can accept or reject electronically within 8 days
- Ticari Senaryo (Commercial): higher-scrutiny B2B where recipient must formally accept or reject within 8 days; failure to respond counts as rejection

For most transactions, Temel Senaryo applies. Ticari Senaryo is used when the invoicing party requests formal acceptance.

**E-Arsiv for smaller amounts and consumers**
E-Arsiv (electronic archive) is the version of e-invoicing for:
- B2C invoices regardless of amount
- B2B invoices to non-e-Fatura companies above TRY 3,000
- All invoices above TRY 30,000 (mandatory e-Arsiv regardless of recipient)

E-Arsiv invoices are issued through the GIB e-Arsiv Portal or via service providers and are sent electronically (email, portal) to recipients.

**Penalties for non-compliance**
Issuing a paper invoice when e-Fatura was required: Ozel Usulsuzluk Cezası of 10% of the invoice amount, minimum TRY 8,800 per invoice (2025 rates). The recipient also loses the ability to claim input KDV on the incorrectly issued invoice, a double penalty for the transaction.

## Real-world examples

### Software company crossing the threshold

A SaaS company had TRY 2.5m revenue in 2024 but expects TRY 4m in 2025. It must be live on e-Fatura by 1 July 2026 (based on 2025 crossing the threshold). It engages an e-dönüsüm provider in May 2026 to allow adequate setup time.

### New exporter: mandatory from day one

A manufacturer makes its first export shipment in March 2025. Regardless of annual turnover, the export invoice must be issued in e-Fatura format integrated with the customs declaration. E-Fatura setup must be completed before the first export.

## Common mistakes to avoid

- Crossing the threshold in year N but not setting up e-Fatura until year N+2: transition is required by 1 July of year N+1
- Assuming the TRY 3,000,000 is net of KDV: it is gross turnover; a business with TRY 2.6m net + 20% KDV = TRY 3.12m gross has already crossed the threshold
- Setting up e-Fatura but forgetting e-Defter: both must be activated together

## Frequently asked questions

### Can a small business below TRY 3,000,000 voluntarily use e-Fatura?

Yes. Any business can voluntarily join the e-Fatura system earlier than required. There is no penalty for early adoption. Many small businesses join voluntarily because clients above the threshold require e-Fatura invoices from their suppliers.

## Practical tips

- Budget for an e-dönüsüm service provider: trying to manage 100+ invoices per month through the GIB Portal manually is impractical
- Add VKN lookup to your invoicing workflow: always check whether the customer is on e-Fatura before raising an invoice
