Running an Online Business in Turkey in 2026: The Operator's Guide

Turkey is an attractive place to sell online for the reasons the data shows: 4.567 trillion TL of e-commerce volume in 2025, 6.9% of GDP, a young mobile-first buyer base, and delivery infrastructure that averages 42.2 hours nationwide. It is also a market where foreign operators regularly get six months in before discovering an obligation they should have handled in week one. This guide runs the gates in the order they actually bite. One boundary up front: we build the software. Everything below about legal and tax obligations is a summary of published sources to help you ask the right questions, and it is not legal or tax advice. Get a Turkish lawyer and a mali müşavir before you commit.

Gate one, presence. Turkish law does not lay down a blanket rule that every foreign e-commerce company must incorporate locally to sell into Turkey. What it does instead is create a set of indirect obligations, tax registration, consumer-law duties, invoicing, payment acceptance and platform requirements, that in combination often make a local entity the practical path. The mistake we see is treating this as a binary yes-or-no question answered from a forum post. The right version is a short scoping conversation with a Turkish advisor about your specific model: are you shipping from abroad or holding stock locally, are you selling B2C or B2B, are you operating your own storefront or intermediating between other sellers. Those answers change the obligation set completely.

Gate two, ETBIS. Under Law No. 6563 on the Regulation of Electronic Commerce, e-commerce activity in Turkey is reported through ETBIS, the Ministry of Commerce's electronic commerce information system. Registration duties cover businesses operating in Turkey, and the reported data typically includes trade registry and tax identification details, contact email, and the payment methods you accept. The distinction that matters most for your architecture is between an ETHS, a service provider selling its own goods, and an ETAHS, a marketplace operator intermediating between other sellers. If your product lets third parties list and sell, you may be building an ETAHS, and marketplace operators face a substantially heavier regime including licensing obligations tied to net transaction volume thresholds. Founders build marketplace features casually and inherit the marketplace regulatory burden by accident.

Gate three, consumer law as of 1 January 2026. The amended Distance Contracts Regulation, published in the Official Gazette on 24 May 2025, is now in force and it moved two things that directly affect your unit economics. First, the exception that used to remove withdrawal rights on mobile phones, smartwatches, tablets and computers was repealed, so those categories now carry the general withdrawal right. Second, the rules tightened around return costs so that they are not pushed onto the consumer where the seller has designated the return carrier in the pre-contract information. There are also expanded pre-contract disclosure requirements. If you sell electronics into Turkey, your return reserve and your checkout disclosures both need revisiting; confirm the specifics with your lawyer, since regulation summaries in English have circulated with this change described backwards.

Gate four, payments. Two-thirds of Turkish e-commerce volume runs on cards, 64% of card transactions are 3D Secure verified, and instalment payment is a baseline consumer expectation rather than a premium feature. Practically this means a domestic payment provider rather than only an international gateway. Published single-payment domestic bands sit around 1.19-1.95% for iyzico and 0.99-1.49% for PayTR, with the wider market roughly 1.29-3.49% depending on volume, sector and instalment mix; rates are negotiated, so get a current quote. Evaluate on total cost, settlement period, instalment handling and chargeback support, not the headline percentage. International merchants who launch with a wallets-plus-cards mix and no instalments consistently under-convert here, and they usually misdiagnose it as a marketing problem.

Gate five, logistics and the delivery promise. Average national delivery is 42.2 hours and 53% of orders arrive within 24 to 48 hours. Your customers apply that benchmark to you regardless of your size. Operationally this means integrating with the domestic carriers from the start (Yurtiçi, Aras, MNG and the rest), automating label generation and tracking rather than handling it manually, and setting dispatch promises you can actually keep, because missed dispatch windows are penalised on marketplaces and punished by reviews on your own store.

Gate six, tax and invoicing, briefly and with the same disclaimer. VAT applies to sales into Turkey, e-invoicing and e-archive obligations exist and are threshold-based, and both interact with whether you have a local entity. This is the area where foreign operators most often assume their home-country setup transfers, and it does not. Budget for a Turkish accountant from month one, and build your order system so that invoice data can be pushed to whatever e-invoice integrator your accountant specifies. Retrofitting invoicing into an order pipeline is unpleasant; designing the hook in advance costs almost nothing.

The stack that satisfies all of the above. Server-rendered storefront so search engines and AI assistants can read your catalogue without executing JavaScript, which in a market with 634,000 competing sellers is a discovery advantage rather than a technical nicety. Domestic payment integration with instalments and 3D Secure as the default path. Cargo integration wired to your order state machine. Distance-selling compliance built into checkout: pre-contract information, the distance sales agreement, withdrawal flow and the disclosures as they stand after 1 January 2026. Structured product data with Schema.org markup. Turkish and English content that is genuinely written in both, not machine-translated, because Turkish buyers detect translated copy immediately and it costs conversion.

What we would do in the first ninety days. Weeks one to two: advisor conversations on entity, tax and ETBIS obligations for your specific model, in parallel with payment provider quotes. Weeks three to six: build the storefront with payment, cargo and compliance surfaces included rather than deferred. Weeks seven to eight: catalogue, structured data, Turkish content written by a Turkish speaker, and the invoicing hook. Weeks nine to twelve: soft launch on a narrow category, measure delivery performance against the 42-hour benchmark, then scale spend once the operation holds. The failure pattern is the inverse: launch with a translated storefront and an international gateway, discover the compliance and payment gaps under load, and rebuild while burning acquisition budget.

One last strategic note for foreign operators. The Turkish market's competitive structure, 634,000 registered sellers with 75% sole proprietorships, means you will not win on price and you do not need to. The field is enormous in count and thin in operational quality. A properly built store with real Turkish-language content, honest delivery promises, instalment payments and clean compliance clears a bar most of the market cannot clear. That is the entry strategy the data supports.
