Consulting Firm Registration in Turkey: Professional Services 2026
Once you have decided on a legal structure — see our companion guide on the strategic side of consulting company formation — this article walks through the actual registration checklist: documents, MERSIS filing, chamber registration and the accounts you need open before you can legally invoice a client.
MERSIS Filing and Trade Registry Steps
Company registration in Turkey runs through the MERSIS electronic system, which generates your company's founding documents (articles of association) based on information entered online, followed by notarised signature circulars and formal registration at the Trade Registry Office — see our LTD formation guide for the general document checklist. For a consulting business, the activity description entered at this stage should specifically reflect your actual service lines (management consulting, IT consulting, HR consulting, etc.), since this affects both your NACE activity code and, in some cases, the chamber you are registered under.
Chamber of Commerce Registration
Every registered company must join the relevant Chamber of Commerce (or Chamber of Industry, depending on activity classification) within the statutory period following incorporation — this is not optional and carries its own registration fee and annual dues. A consulting firm generally registers under the Chamber of Commerce rather than Industry, given the service (not manufacturing) nature of the activity.
Tax Office Registration and E-Invoice Enrolment
After Trade Registry completion, register with the local tax office to obtain your tax certificate, and confirm whether your projected transaction volume requires mandatory e-Fatura/e-Arşiv enrolment from your first invoice — many consulting firms serving both local and international clients enrol voluntarily even below the mandatory threshold, since it simplifies invoicing for corporate clients who increasingly expect e-invoices.
Opening the Corporate Bank Account
You cannot complete company registration or receive client payments without a corporate bank account, and banks require your finalised trade registry documents, tax certificate and signature circular before opening one — see our bank account opening guide for what documentation to prepare in advance so this step does not become the bottleneck in your registration timeline.
Frequently Asked Questions
What is MERSIS and do I need to use it myself?
MERSIS is Turkey's electronic company registration system used to generate founding documents and register with the Trade Registry. Most foreign entrepreneurs use a lawyer or company formation consultant to handle the MERSIS filing rather than navigating it directly, since it is in Turkish and tied to specific legal formatting requirements.
Is chamber of commerce registration optional for a small consulting firm?
No, it is mandatory for every registered company within a statutory period after incorporation, regardless of company size, and carries its own registration fee plus annual dues. A consulting firm typically registers under the Chamber of Commerce given its service-sector activity.
Can I invoice clients before my corporate bank account is open?
Practically no — you need the account both to receive payments and because banks require your finalised registration documents first, which typically follow the same sequence as your other registration steps. Plan for the bank account opening to be one of the final steps before you can start operating.
Conclusion
Registering a consulting firm in Turkey follows a defined sequence — MERSIS filing, chamber registration, tax office registration, and corporate bank account opening — each with its own document requirements and, in the case of chamber registration, its own mandatory fees. For the strategic decisions that should be made before you start this process (legal structure, foreign ownership positioning), see our companion guide on consulting company formation.
