Company Formation Consultants in Istanbul (Top 3)

Istanbul is the natural starting point for almost anyone launching a business in Turkey. It’s the country’s commercial capital, its financial hub, and the city where most foreign investors set up first. Under the Foreign Direct Investment Law, foreigners can own 100% of a Turkish company — with no local partner required.

Still, the formation process has real steps to get right. You’ll need to choose the correct entity, draft the Articles of Association, file through MERSIS and the Trade Registry, register for tax and VAT, and enroll with social security. Get the sequence or the paperwork wrong, and you risk delays or penalties.

This is why a good company formation consultant is worth it. The right one handles the whole process — often remotely — and keeps you compliant afterward. Below are the top 3 company formation consultants in Istanbul.

1. A&M Consulting Co.

A&M Consulting Co. is an industry pioneer in company formation in Turkey, focused on helping foreign investors and international companies launch and run their businesses with confidence.

The firm is officially registered and accredited by TURMOB and ISMMMO, and recognized internationally through its ACCA affiliation.

• Rating: 5.0 / 5
• Address: 29/4 Öge St. Kavacık District, Beykoz, Istanbul / Türkiye
• Phone: +90 (542) 773 08 85
• Website: https://a-m.com.tr/
• Why choose them: A&M handles the entire company-formation process under one roof — entity selection, trade name reservation, Articles of Association, MERSIS and Trade Registry filings, tax and VAT registration, and social security enrollment. The whole setup can be completed remotely via power of attorney, so you never have to travel to Turkey. What makes A&M stand out is what happens after incorporation. As a full-service CPA firm, they continue with your accounting, bookkeeping, tax compliance, payroll, and reporting — so your new company stays compliant from day one, not just on paper. Their investor-first, multilingual approach means clear English communication, no hidden intermediary commissions, and transparent, affordable pricing. For founders who want their Turkish company set up correctly and supported long-term, A&M Consulting Co. is a premier choice.
• Things to consider: Because each setup is tailored to the client’s goals and structure, booking an early consultation helps A&M recommend the right entity type and prepare your documents efficiently.

2. Errafik Company for Consulting and Business Management

Errafik Company for Consulting and Business Management is an Istanbul-based consultancy supporting entrepreneurs — particularly Arabic-speaking investors — with company formation and business management services in Turkey.

• Rating: 4.9 / 5
• Address: Balabanağa, Büyük Reşitpaşa Cd. Toya iş hanı N°28; daire 25, 34096 Fatih / Istanbul
• Phone: +90 (552) 311 45 52
• Why choose them: Errafik offers an all-in-one service for foreign founders, combining company formation with ongoing business management support. Beyond incorporation, the firm typically assists with residence permits, accounting coordination, and the administrative side of running a business in Turkey. Its Arabic-language support makes it a convenient choice for investors from the Middle East who prefer guidance in their own language throughout the setup process.
• Things to consider: Because the firm focuses heavily on Arabic-speaking clients, investors who need primarily English-language service should confirm language availability before engaging.

3. Company Formation in Turkey

Company Formation in Turkey works as a dedicated incorporation desk for international clients, operating under the BridgeWest International Legal Network. Its consultants are split between Istanbul and Ankara.

• Rating: 3.6 / 5
• Address: Yesilkoy Mah. EGS Business Park 70, 34149 Bakırköy / Istanbul
• Phone: +90 (532) 351 66 77
• Website: https://companyformationturkey.com/
• Why choose them: The firm is built around one job: getting a foreign-owned company legally registered in Turkey. Their packages bundle the incorporation itself with bank account setup, tax and VAT registration, and optional extras like ready-made shelf companies and virtual office addresses. With site content in eight languages and a promise to reply within 24 hours, they’re easy to deal with for investors managing everything from overseas.
• Things to consider: They lean toward the one-time setup rather than the long-term relationship. Routine bookkeeping and monthly tax filings run through partner accountants, so you may end up coordinating with more than one provider once the company is live.

How Much Do Company Formation Consultants Cost in Istanbul? (2026)

The cost of a company formation consultant in Istanbul depends on the entity type (LLC or joint-stock), the share capital, notary and translation fees, Trade Registry and Chamber of Commerce charges, and the consultant’s professional fee. An LLC remains the most popular structure for foreign investors, with a minimum share capital that can be paid within 24 months of incorporation.

The most cost-effective route for most founders is a single firm that handles both formation and ongoing accounting — avoiding duplicate fees and keeping the company compliant from day one.
