Türkiye KDV for Foreign & Local Businesses — 2026 Guide

The 20% standard rate, the world’s most mature mandatory e-invoicing stack, the Tevkifat withholding system, the foreign digital services regime, and the operational architecture for trading into and inside Eurasia’s largest emerging market.

In 2030, when the EU’s ViDA package brings mandatory cross-border B2B e-invoicing and Digital Reporting Requirements into force across all twenty-seven Member States, the operational baseline that European businesses will be implementing for the first time will look — in most material respects — like the Turkish system that has been running since 2014. The e-Fatura stack (B2B e-invoicing through a centralised tax-authority platform), the e-Arşiv Fatura supplement (B2C invoice archiving in the same system), the e-Defter ledger (electronic accounting transmission to the tax authority on a monthly cycle), and the e-İrsaliye delivery note system (real-time tracking of physical goods movements): each layer of the Turkish framework predates the EU equivalent by between four and sixteen years.

Türkiye is, on the strength of that operational maturity alone, one of the world’s most digitally supervised KDV jurisdictions. Foreign vendors trading into Türkiye and Turkish-resident businesses operating above the e-Fatura threshold (broadly TRY 3 million annual revenue, with lower thresholds for e-commerce, fuel, alcohol, and tobacco sectors) operate in an environment where every invoice is visible to Gelir İdaresi Başkanlığı (GIB) in near-real-time, every accounting ledger is transmitted monthly, and every truck moving goods above the value threshold is tracked through e-İrsaliye before it leaves the depot. Compounding the data depth is the Tevkifat withholding system — a partial-VAT-withholding mechanism unique among major economies, in which the recipient of a B2B service withholds a defined percentage of the VAT and remits it directly to GIB on behalf of the supplier.

This guide is the operator’s view of how Turkish KDV actually works in 2026. We cover where the 20% standard rate applies and where 10% reduced and 1% super-reduced bands take over, how the e-Fatura and Tevkifat systems integrate with normal commercial workflows, what foreign vendors need to do under the Resident Tax Number scheme for B2C digital services, how the Türkiye–EU customs union shapes goods movements, and what changes are visible on the GIB roadmap as the e-invoicing framework continues to expand.

01 · Snapshot — Turkish KDV at a glance

Everything you need to orient before reading the persona tracks. Every figure here is restated and sourced inside the relevant track.

02 · 60-second self-check — does this guide apply to you?

Six questions. If any answer is yes, the corresponding track is mandatory reading before you transact.

03 · Track 1 — Foreign vendor selling B2B services or goods into Türkiye

You are established outside Türkiye and you sell B2B services or higher-value goods to Turkish customers. Türkiye’s customs union with the EU simplifies certain goods mechanics; its KDV system is independent of EU VAT and operates on its own framework.

3.1 B2B services — reverse charge and KDV-2

For B2B services with place of supply in Türkiye, Article 9 of the KDV Law applies the recipient-location reverse-charge mechanism: the Turkish recipient (where a KDV-registered taxpayer) self-assesses KDV at 20% (or appropriate reduced rate) on the value of the service. The foreign supplier invoices without Turkish KDV, and the Turkish recipient files Form KDV-2 declaring the reverse-charged KDV on the next monthly KDV return.

Operationally:

• The foreign supplier does not need to register for Turkish KDV for B2B services covered by the reverse-charge mechanism.
• The Turkish recipient self-assesses 20% KDV and deducts it in the same return at the appropriate input recovery ratio.
• The supplier invoice should reference the foreign supplier’s home-country tax number and the description of the service. No specific Turkish wording is mandatory but commercial best practice is to mark the invoice “KDV not applied — Turkish recipient subject to reverse charge under Article 9 KDV Law”.

3.2 B2B goods — Türkiye–EU customs union and the KDV mechanism

For goods imported into Türkiye, the importer of record pays Turkish import KDV (20% on the customs value plus duty, or appropriate reduced rate for in-scope categories) and recovers it through the next monthly KDV return where the importer is a Turkish KDV-registered taxpayer.

The Türkiye–EU Customs Union, in force since 1995, eliminates customs duties on most industrial goods (and certain processed agricultural products) between Türkiye and the EU. This is a customs-duty concession only — KDV applies to all imports regardless of country of origin. EU exporters benefit from the customs-duty elimination but not from any KDV elimination.

DDP versus DAP terms determine who acts as importer:

• DAP / DDU: Turkish customer is importer of record, pays import KDV, recovers it. Foreign supplier ships without Turkish KDV involvement and does not need Turkish KDV registration.
• DDP: Foreign supplier is importer of record, pays import KDV, becomes liable for Turkish KDV on subsequent domestic supply. Direct Turkish KDV registration is required.

3.3 When direct Turkish KDV registration becomes unavoidable

Foreign vendors must register directly for Turkish KDV when:

• They hold stock in Türkiye (consignment warehouse, fulfilment centre).
• They act as importer of record for Turkish imports.
• They make B2C supplies of services to Turkish consumers (subject to the Resident Tax Number simplified scheme — Track 2).
• They provide services with place of supply in Türkiye that are not covered by the reverse-charge mechanism (immovable property services on Turkish buildings, conference services held in Türkiye).

3.4 Registration mechanics

Standard Turkish KDV registration for foreign-established businesses requires the appointment of a Turkish tax representative (vergi temsilcisi) and is filed through the GIB Interactive Tax Office (İnteraktif Vergi Dairesi). The application requires:

• Certificate of incorporation translated into Turkish.
• Identification of beneficial owners and directors.
• Turkish tax representative appointment with notarised power of attorney.
• Description of intended Turkish activity.
• Turkish bank account (typically required by GIB though not strictly mandatory).

Processing typically takes 4–8 weeks. The Turkish tax representative holds joint and several liability for unpaid KDV and is operationally essential — Turkish-language correspondence with GIB, audit response, e-Fatura integration, and Tevkifat compliance all flow through the representative. Budget TRY 250,000–TRY 600,000 per year (approximately €7,000–€16,000 at 2026 exchange rates) for a competent Turkish tax representative providing return preparation and routine compliance.

04 · Track 2 — Foreign vendor selling B2C goods or digital services into Türkiye

You are established outside Türkiye and you sell directly to Turkish consumers — physical goods, digital services, or both. The mechanics differ materially between goods and digital services because Türkiye operates a dedicated simplified scheme for foreign suppliers of B2C electronic services.

4.1 Worked example — Stockholm Fashion Brands AB

Stockholm Fashion Brands AB is a Swedish fast-fashion direct-to-consumer brand selling clothing and accessories through:

• A Turkish-language Shopify storefront targeting Turkish consumers (B2C, average order value TRY 4,800, approximately 8,500 orders per month).
• Listings on Trendyol and Hepsiburada (Türkiye’s dominant marketplaces) through a Turkish-licensed e-commerce reseller (the reseller is Stockholm Fashion’s importer of record for marketplace inventory).
• A small B2B wholesale channel to Turkish boutique fashion retailers (B2B, average order value TRY 85,000).

Their KDV architecture decomposes into three streams:

Stream A — Direct B2C Shopify sales. Stockholm Fashion ships from a Hamburg warehouse to Turkish consumers under DDP terms (delivered duty paid). To execute DDP, Stockholm Fashion must register for Turkish KDV (with Turkish tax representative) and act as importer of record. At import, they pay 20% Turkish KDV on the customs value plus any duty (clothing customs duty for non-Türkiye–EU-customs-union origins can be material; for EU-origin goods like Stockholm Fashion’s Swedish-warehoused inventory the customs union eliminates duty, but KDV still applies). At checkout in Türkiye, they charge 20% KDV to consumers. The import KDV is recoverable via their monthly KDV return; the consumer KDV is output collected. The net KDV payable equals the output KDV less recoverable input KDV — typically a positive remittance unless heavy refurbishment/marketing inputs.

Stream B — Marketplace channel through the Turkish reseller. The Turkish reseller is importer of record for inventory shipped to Trendyol/Hepsiburada fulfilment centres. Stockholm Fashion invoices the Turkish reseller in EUR at wholesale prices; the supply is an export from Sweden / import into Türkiye, and the Turkish reseller handles all Turkish KDV mechanics. Stockholm Fashion is not Turkish-KDV-registered for this stream. The commercial arrangement places the Turkish KDV burden on the reseller, who reflects it in wholesale margin.

Stream C — B2B wholesale to Turkish boutiques. Stockholm Fashion sells directly to a small number of Turkish boutique retailers. Each shipment clears Turkish customs in the boutique’s name (DAP terms). The boutique pays import KDV at 20% and recovers it on their next monthly return. Stockholm Fashion invoices without Turkish KDV — “export from Sweden — zero-rated under Swedish moms framework, recipient subject to Turkish import KDV”. No Turkish KDV registration is required for this stream because the customer is importer of record.

4.2 The Resident Tax Number scheme for B2C digital services

If Stockholm Fashion Brands also operated a paid styling-advice video subscription for Turkish consumers, those B2C digital services would fall under the Resident Tax Number scheme — operational in Türkiye since 1 January 2018. The scheme:

• Applies to foreign suppliers of electronic services, telecommunications, and broadcasting services to Turkish consumers (B2C only — B2B follows reverse charge as in Track 1).
• Requires simplified online registration through the GIB Interactive Tax Office.
• Issues a Resident Tax Number (not a full KDV number) for VAT compliance only.
• Requires 20% KDV charged on B2C supplies to Turkish consumers.
• Monthly filing through the simplified scheme portal.
• No fiscal representative required (the simplified scheme bypasses the standard fiscal-representative requirement).

The scheme has brought tens of thousands of foreign digital service providers — Netflix, Spotify, Apple, Microsoft, Adobe, Zoom, AWS, Google Cloud — into the Turkish KDV system. Foreign vendors using the Resident Tax Number scheme do not have access to input VAT recovery; the scheme is a collection-only mechanism similar to Norway’s VOES.

05 · Track 3 — Free zones, exports, marketplaces, and sector-specific frameworks

Turkish KDV has several operationally distinctive sector frameworks: the free-zone framework with comprehensive KDV exemptions, the export-incentive framework, the Tevkifat withholding system that runs in parallel with standard KDV, and dedicated rules for energy, telecommunications, and banking sectors.

5.1 Turkish free zones

Türkiye operates 18 free zones across the country, including major hubs at Istanbul Atatürk Airport, İzmir Aegean, Mersin Mediterranean, and Bursa. Supplies of goods and services within a free zone are KDV-exempt; supplies between free zones and the Turkish domestic territory are treated as imports/exports. Operators with a Turkish presence centred in a free zone benefit from:

• KDV exemption on intra-zone supplies and on supplies to international customers from the zone.
• Corporate income tax exemption on income earned within the zone (separate from KDV).
• Customs duty exemption for goods entering the zone for re-export.

Free zones are particularly attractive to manufacturing-for-export operators, logistics hubs, and processing-trade businesses. For foreign vendors selling into Turkish free-zone customers, the supply is typically zero-rated as an export — even though the goods physically arrive in Türkiye.

5.2 Tevkifat — partial KDV withholding

Tevkifat (withholding) is the Turkish system of partial KDV withholding on specific B2B services and supplies. Under Tevkifat, the recipient of a service withholds a percentage of the KDV charged by the supplier and remits it directly to GIB; the supplier receives only the net amount and reports the withheld portion as KDV-already-withheld on the supplier’s KDV return.

Tevkifat percentages vary by transaction type and are set by GIB communiqués. Examples (subject to current GIB publication):

• Construction and assembly works to government entities: typically 30%–40% withholding.
• Construction services to private-sector buyers: typically 30%.
• Cleaning, security, transport, and labour-supply services: typically 90% (very high withholding).
• Consultancy, advisory, accountancy services: typically 50%–60%.
• Goods sales: generally no Tevkifat, though specific high-risk goods categories may apply.

Operational implications: a Turkish supplier issuing a TRY 100,000 service invoice subject to 50% Tevkifat will receive TRY 90,000 from the customer (TRY 100,000 + TRY 20,000 KDV − TRY 10,000 withheld) and report TRY 20,000 of output KDV on their return with a TRY 10,000 credit for the withheld portion. The net cash impact to the supplier: receive TRY 100,000 cash equivalent but with TRY 10,000 of KDV cash advanced by the customer to GIB on their behalf. The customer benefits from accelerated KDV remittance to GIB. The system reduces VAT-fraud risk and improves Treasury cash flow.

Foreign vendors selling B2B services into Türkiye are themselves usually not subject to Tevkifat — the reverse-charge mechanism described in Track 1 covers the standard case. Tevkifat applies primarily to domestic Turkish supplier-to-customer transactions.

5.3 Marketplace dynamics

Türkiye’s e-commerce market is dominated by Trendyol, Hepsiburada, and N11, plus Amazon Turkey and several smaller players. Marketplace operators handle KDV at the platform level for transactions involving Turkish-resident sellers. For foreign sellers, the standard mechanic is to operate through a Turkish-licensed import/reseller partner (as Stockholm Fashion does for Stream B in the worked example) — the partner becomes the Turkish KDV-registered party and the foreign seller treats the supply as an export.

Direct foreign-seller participation on Turkish marketplaces is operationally limited because most platforms require Turkish KDV registration and Turkish bank account details for seller settlement. Foreign vendors typically structure through Turkish entities or licensed reseller partnerships rather than attempting direct registration.

06 · Track 4 — Local Turkish business — KDV, e-Fatura, e-Defter, Tevkifat

If you operate a Turkish-resident business — an Anonim Şirket (A.Ş.), Limited Şirket (Ltd. Şti.), Şahıs Şirketi (sole proprietorship), or Turkish branch of a foreign group — your KDV obligations are operationally complex because of the layered e-invoicing, e-ledger, e-delivery-note, and Tevkifat mechanics that overlay standard KDV.

6.1 Registration — no threshold

Türkiye does not operate a small-business KDV exemption threshold equivalent to those found in EU jurisdictions. Every Turkish-resident business with taxable supplies must register for KDV from the first taxable supply. The only carve-out is the simplified taxation regime (Basit Usul) for very small sole traders and certain occupations — these taxpayers are taxed under simplified income-tax rules and are KDV-exempt by operation of that regime, but the eligibility is narrow.

6.2 Monthly filing

Standard KDV filing cadence is monthly. The KDV return (Form KDV-1) and the reverse-charge return (Form KDV-2) are both filed by the 26th of the month following the reporting month. Payment is also due by the 26th. Annual filing is not available for active commercial taxpayers; quarterly filing is reserved for narrow categories.

6.3 e-Fatura — operational mechanics

The e-Fatura system has been mandatory for Turkish taxpayers above defined thresholds since 2014. Coverage has expanded continuously through GIB communiqués; as of 2026 the framework applies broadly as follows:

• Mandatory e-Fatura: taxpayers with previous-year gross sales above TRY 3 million (general threshold; lower for e-commerce, fuel, alcohol, tobacco sectors).
• Mandatory e-Arşiv Fatura: e-Fatura-registered taxpayers must issue e-Arşiv Fatura for all invoices to non-e-Fatura-registered customers.
• Mandatory e-Defter: e-Fatura-registered taxpayers must transmit general ledger and subsidiary ledger to GIB monthly in the e-Defter format.
• Mandatory e-İrsaliye: for goods movements above defined value thresholds, electronic delivery notes must be issued and transmitted to GIB before the goods leave the premises.

e-Fatura invoices are XML files transmitted to GIB through the Electronic Invoice System (EFKS). Two operational models:

• Direct integration: large taxpayers connect their ERP/accounting system directly to the GIB EFKS API.
• Authorised e-invoicing service providers (Özel Entegratör): most SMEs use GIB-authorised intermediary service providers (Logo, Idea, Mikro, Netsis, eFinans, Foriba) that handle the API integration.

6.4 Filing and reconciliation

The monthly KDV return reconciles output KDV (from e-Fatura outputs), input KDV (from e-Fatura inputs and import-VAT entries), withholding adjustments (from Tevkifat), and any reverse-charge entries (from Form KDV-2). The KDV system is closely tied to the broader e-Defter ledger, and GIB’s analytical systems cross-match invoice-level data, ledger entries, and KDV-return figures within days of submission. Reconciliation gaps trigger structured queries with short response windows.

07 · Cross-track essentials — invoicing, withholding, currency, ViDA-equivalent alignment

7.1 Invoice content requirements

Turkish KDV invoices must contain the elements set out in the Tax Procedure Law (Article 230) and KDV Law:

• Supplier full name, address, and Turkish tax number (Vergi Kimlik Numarası — VKN).
• Customer name and address (and Turkish VKN where the customer is Turkish-resident).
• Invoice number from a continuous numerical series — for e-Fatura, automatically generated by the system.
• Date of issue and date of supply.
• Description, quantity, and unit price of goods or services.
• KDV rate applied, KDV amount per line, and total KDV charged.
• Total amount payable in TRY (foreign currency permitted with TRY equivalent at Central Bank rate).
• Tevkifat withholding details where applicable (Tevkifat percentage, withheld amount, net payable).

7.2 Currency and exchange rates

KDV returns must be filed in TRY. Foreign-currency invoices must be converted to TRY using the Türkiye Cumhuriyet Merkez Bankası (TCMB — Central Bank of the Republic of Türkiye) reference exchange rate of the date of supply. TCMB publishes daily reference rates that are the legally required conversion source. High volatility in TRY exchange rates makes the rate-of-supply application materially important — supplies invoiced in EUR or USD against later-paid TRY can create significant translation adjustments.

7.3 ViDA-equivalent alignment

Türkiye is not bound by ViDA (which is an EU regulation), but the Turkish e-Fatura framework already implements substantially everything ViDA will require of EU Member States by 2030. Operational implications for businesses spanning the EU and Türkiye:

• Multi-jurisdiction operators with EU and Turkish presence should build e-invoicing and DRR systems to handle the Turkish framework today — by 2030 those same systems will satisfy EU requirements.
• The Turkish e-Fatura XML schema is structurally similar but not identical to EN 16931 / Peppol BIS Billing 3.0. Conversion mappings between the two schemas exist and are operationally manageable.
• Turkish suppliers selling into the EU should prepare for EU customers to require Peppol-format invoices from 1 July 2030; existing Turkish e-Fatura infrastructure simplifies the adaptation.

08 · Common questions answered properly

Q. The KDV rate rise from 18% to 20% in July 2023 — how do we handle long-term contracts spanning the change?

The supply tax point determines the rate. Supplies with tax point on or before 9 July 2023 use 18%; supplies with tax point on or after 10 July 2023 use 20%. For long-term contracts, individual deliveries or service-period segments use the rate in force on their respective tax points. The 1 July 2023 to 10 July 2023 ten-day window is the transition zone — GIB published transitional guidance in early July 2023. Multi-year contracts straddling the change should have been re-papered to reflect the rate change; if not, the post-change supplies still use 20% even if the contract was signed under 18%.

Q. We’re a foreign SaaS company selling to Turkish businesses. Do we need a Resident Tax Number?

Only for B2C supplies. The Resident Tax Number scheme covers B2C electronic services to Turkish consumers. For B2B SaaS to Turkish businesses, the standard reverse-charge mechanism applies — the Turkish business self-assesses 20% KDV via Form KDV-2. You don’t register; you invoice without Turkish KDV. The Resident Tax Number is required only if you have B2C revenue from Turkish consumers.

Q. Our Turkish supplier invoices us with 50% Tevkifat. What does that mean operationally?

A 50% Tevkifat means the customer (you) withholds 50% of the KDV charged by the supplier and remits it directly to GIB on the supplier’s behalf. Example: supplier invoices TRY 100,000 + TRY 20,000 KDV = TRY 120,000 total. With 50% Tevkifat: you pay the supplier TRY 110,000 (TRY 100,000 + TRY 10,000 KDV — the non-withheld 50% of KDV) and you remit TRY 10,000 (the withheld 50%) directly to GIB. The supplier reports TRY 20,000 of output KDV on their return with a TRY 10,000 credit for the customer-withheld portion. You report TRY 20,000 of input KDV on your return (deductible at your normal recovery ratio) and TRY 10,000 of Tevkifat-paid on Form KDV-2. The net result is identical to a non-Tevkifat transaction; the cash flow is accelerated to GIB.

Q. We sell B2C clothing to Turkish consumers. The customs duty under EU customs union — does it apply to us?

Depends on the goods origin. The Türkiye–EU Customs Union covers industrial goods of EU origin or with sufficient EU processing under the rules-of-origin framework. Clothing originating in the EU benefits from zero customs duty entering Türkiye. Clothing originating outside the EU — manufactured in Bangladesh, China, India, Vietnam, etc. — does not benefit from the customs union even if shipped from an EU warehouse, and standard Turkish customs duty applies (10–20% for clothing typically) on top of 20% KDV. The origin documentation (A.TR Movement Certificate for EU-origin goods) is essential; without it, no customs union benefit.

Q. We’re a Turkish AŞ above the e-Fatura threshold. Our ERP doesn’t speak e-Fatura. What do we do?

Use an authorised e-invoicing service provider (Özel Entegratör). The providers — Logo, Idea, Mikro, Netsis, eFinans, Foriba, and others — accept structured invoice data from any ERP (often via Excel/CSV upload, SOAP/REST API, or direct EDI integration) and handle the GIB EFKS transmission, format validation, and response handling on your behalf. The cost is generally TRY 2,000–TRY 12,000 per month depending on volume. For larger taxpayers (typically TRY 30M+ annual revenue), direct GIB EFKS integration is more cost-efficient over a 3+ year horizon but requires meaningful ERP development. Most SMEs choose Özel Entegratör for years 1–3, then evaluate direct integration as volumes scale.

Q. The TRY exchange rate is moving 2–3% per week. How do we handle invoice-vs-payment timing differences?

KDV is assessed at the rate of supply, not the rate of payment. An invoice issued at TRY 100,000 in March with 20% KDV (TRY 20,000) generates a March KDV liability of TRY 20,000 regardless of when the customer actually pays. If the customer pays in May with the TRY 30% weaker against EUR than at invoice date, the EUR economics shift but the TRY KDV liability is fixed at TRY 20,000. The exchange-rate risk between invoice and payment is a commercial risk borne by the supplier or addressed contractually through TRY-pegged or FX-adjusted pricing terms. Many Turkish suppliers operating with foreign customers now contract in EUR or USD with TRY conversion at payment date for the FX-risk portion, while KDV remains TRY-fixed at invoice date.

Q. Do we need a Turkish bank account for KDV remittance?

Effectively yes for active operations. KDV remittances must be made to a Turkish bank account designated for tax payments; international wire transfers to GIB are not the practical norm. Foreign businesses operating without a Turkish entity typically remit through their tax representative’s account or open a Turkish bank account through one of the Turkish banks (Türkiye İş Bankası, Garanti BBVA, Akbank, Yapı Kredi). For the Resident Tax Number scheme for B2C digital services, GIB accepts wire transfers from any international account, simplifying the process for foreign digital service providers.

09 · Recent changes and the road ahead

2014–2018 — e-Fatura, e-Defter, e-Arşiv rollout

The Turkish e-invoicing framework launched with e-Fatura in 2014, expanded with e-Defter (ledgers) and e-Arşiv Fatura (B2C invoices), and steadily lowered turnover thresholds bringing more businesses into scope. By the late 2010s, Türkiye operated one of the most comprehensive mandatory e-invoicing regimes globally.

2018 — Resident Tax Number scheme launch

Effective 1 January 2018, foreign suppliers of B2C electronic services to Turkish consumers became subject to mandatory Turkish KDV registration through the simplified Resident Tax Number scheme. The scheme brought major foreign digital service providers (Netflix, Spotify, Apple Services, Microsoft consumer, AWS consumer, Google consumer) into the Turkish KDV net within months.

2020 — e-İrsaliye expansion

Electronic delivery notes (e-İrsaliye) became mandatory for goods movements above threshold values, with sector-specific lower thresholds for high-risk categories (fuel, tobacco, alcohol). Real-time goods-movement visibility for GIB.

2023 — KDV rate increase

Effective 10 July 2023, the standard KDV rate rose from 18% to 20% and the intermediate rate rose from 8% to 10%. The increase was a fiscal-consolidation measure following high inflation. The 1% super-reduced rate on basic food and books was preserved.

2025 — Continued e-invoicing threshold reduction

GIB lowered e-Fatura and e-Defter thresholds further through 2024–2025, bringing additional small and mid-sized businesses into mandatory scope. By end-2025, the practical reach of e-Fatura covers approximately 80% of Turkish commercial activity by transaction volume.

Outlook 2026–2030

Two trends to monitor: (1) potential further lowering of e-Fatura thresholds to bring micro-businesses into scope (creating a near-universal mandatory regime); (2) potential cross-border B2B e-invoicing requirements aligned with EU ViDA, which would accept Peppol BIS Billing 3.0 invoices from EU suppliers and transmit Turkish e-Fatura invoices to EU recipients in Peppol-compatible format. The technical groundwork is being laid through 2026–2027 in expectation of the EU 2030 mandate.
