# When does a business need to register for KDV (VAT) in Turkey? Last updated: 1 June 2026 Country: Turkey Category: VAT **Quick answer:** In Turkey, KDV (Katma Deger Vergisi) registration is mandatory for virtually all businesses from the date they commence commercial or professional activity. Unlike the UK or EU, Turkey does not have a simple annual turnover registration threshold for most business types: registration is a requirement of commencing taxable activity, not a consequence of exceeding a revenue level. ## Detailed explanation KDV registration in Turkey works very differently from the UK VAT system or German USt registration. Understanding the key differences prevents compliance failures. **No turnover threshold for most businesses** The default rule under KDV Law No. 3065 is that any business conducting taxable activities must be KDV registered. Unlike the UK (£90,000 threshold) or Germany (€22,000 Kleinunternehmer limit), Turkey does not offer a general threshold below which businesses can trade without registering. Registration happens at the same time as general tax registration with the local Vergi Dairesi, typically within days of incorporation. **Exceptions: who does NOT need to register** Three categories of business may be exempt from periodic KDV obligations: 1. Goturu Usul (simplified/flat-rate) taxpayers: Very small tradespeople (bakkal, berber, terzi, small shopkeepers, barbers, tailors) approved for flat-rate income tax treatment pay a fixed annual amount instead of filing detailed KDV returns. Eligibility requires approval from the Tax Office and is restricted to low-turnover sole traders in qualifying trades. 2. Certain financial and insurance services: Banking, insurance, and some capital market transactions are exempt from KDV (but not from alternative taxes like BSMV, Banking and Insurance Transaction Tax, now replaced by Finansal İşlemler Vergisi). 3. Export transactions: Exports are zero-rated (not exempt): exporters are KDV registered and can reclaim input KDV; they simply charge 0% on export sales. **When to register and how** For a new Limited Sirketi or Anonim Sirket: 1. Incorporate the company and receive the Trade Registry number 2. Apply to the local Vergi Dairesi for tax registration (Vergi Mükellefiyeti): within 10 days of incorporation 3. KDV registration is part of the same application; the company is assigned a Vergi Kimlik Numarası (VKN, tax identification number) 4. From the first day of registration, the company must charge KDV on all taxable supplies and file monthly KDV returns For a new sole trader: the process is similar: register with the Vergi Dairesi upon commencing activity. Gercek Usul (actual basis) sole traders register for KDV immediately. **The 20% rate applies from day one** There is no grace period. A company must charge KDV at 20% (standard rate) on its first invoice. Many new entrepreneurs make the mistake of not charging KDV on early invoices, then needing to retrospectively correct or absorb the shortfall. **Input KDV recovery** A key benefit of early registration is input KDV recovery on start-up costs. Pre-registration input KDV (purchased before the formal VKN was issued) can often be recovered if it is directly related to the business, but this requires careful documentation and sometimes a formal adjustment request. **Foreign businesses registering for Turkish KDV** Non-resident companies providing electronic services (cloud services, digital downloads, online advertising) to Turkish consumers must register for Turkish KDV since 2018. Registration is via a simplified online process with GIB. Non-resident B2B service providers typically do not register: their Turkish business customers self-account via the KDV2 reverse-charge mechanism.

Tax registration must be completed by 11 March. From the first client invoice on 15 March, the company charges 20% KDV and files its March KDV return by 28 April 2025. ### UK company providing software to Turkish businesses A UK SaaS company invoices Turkish business clients for cloud software. The Turkish businesses reverse-charge 20% KDV via their monthly KDV2 declarations: the UK company does not need to register in Turkey for B2B supplies. ## Common mistakes to avoid - Issuing the first few invoices without KDV because the business assumed a threshold applied: this creates a liability for unpaid KDV plus penalties - Not filing KDV returns for months with no turnover: a nil (sıfır) KDV return must still be filed monthly for all registered businesses - Forgetting the KDV2 obligation for foreign service purchases: reverse-charge KDV on Google, AWS, and other foreign providers must be declared monthly ## Frequently asked questions ### Is there a KDV exemption for small businesses in Turkey? Only for very small traders approved under the Goturu Usul flat-rate regime. General commercial businesses and all companies (Ltd. or A.S.) must register for KDV from inception: there is no SME turnover threshold exemption as exists in the UK or Germany. ### What KDV rate applies to software and technology services? Software and technology professional services are subject to the standard 20% KDV rate. There is no reduced rate for digital services. SaaS subscriptions, app development, IT consulting: all 20%. ## Practical tips - Complete KDV registration on the same day as your Trade Registry application: delay creates a gap where you cannot legally issue valid tax invoices - Set up your accounting software for KDV from day one; retrospective KDV corrections are complex and time-consuming ## Related questions - [What is the corporate tax rate in Turkey for 2025?](https://accounts-os.com/tr/questions/turkey-corporate-tax-rate-tr) - [When is e-Fatura (e-invoice) mandatory in Turkey and how does it work?](https://accounts-os.com/tr/questions/turkey-e-fatura-requirement-tr) - [What business expenses are deductible for corporate tax in Turkey?](https://accounts-os.com/tr/questions/turkey-business-expense-deductibility-tr)
