Setting up a company in Turkey as a foreigner

Foreign nationals can own 100% of a Turkish limited or joint-stock company. A typical process looks like this:

  1. Choose the company type — Limited company (minimum capital 50,000 TRY) or joint-stock company (minimum capital 250,000 TRY).
  2. Prepare documents — notarised Turkish translation of your passport, a potential tax ID number, company address (lease or title deed) and articles of association.
  3. Registration — application via MERSİS and registration with the Trade Registry; publication in the Trade Registry Gazette.
  4. Tax & bank — tax office inspection and tax certificate, opening of the company bank account, statutory books.
  5. Operations — e-signature / e-seal, e-invoicing and, if you hire staff, social security (SGK) registration.

Timelines depend on document readiness; with complete documents registration is usually completed within a few business days.
