Sahin Tuhan, Certified Public Accountant — Istanbul

About

Hi, I'm Şahin.

I practise as a Certified Public Accountant and tax advisor. I have devoted most of my career to helping businesses not just file their returns, but build sound financial decisions from the ground up. Today I lead a team of 22 at Sistem Global, serving a broad range of clients — from SMEs to international entrepreneurs.

My expertise centres on Turkish corporate and income tax law, but goes well beyond that. I advise on cross-border taxation, technopark regulations and the service-export VAT exemption — because for most businesses the real question is rarely "where does this number go?" but rather "is this structure set up correctly?"

I work with SME owners, freelancers, startup founders and international entrepreneurs looking to do business in Turkey. Turning complex regulations into clear decisions has been the essence of what I do for 23 years.

Frequently Asked Questions

What tax advantages are available for entrepreneurs in Turkey?

In Turkey, entrepreneurs can benefit from technopark exemptions, R&D incentives, young entrepreneur tax deductions and various SME support programs. Additionally, companies investing in regions covered by regional incentives may receive corporate tax reductions, social security premium support and interest subsidies.

What taxes are exempt for companies in Turkish Technoparks?

Companies operating in Technology Development Zones (Technoparks) are exempt from corporate income tax and VAT on revenues derived from software, R&D and design activities until December 31, 2028. Additionally, income tax withholding and employer's social security contributions for R&D personnel working in the zone are also exempt.

Can a foreign national set up a company in Turkey?

Yes, foreign nationals (individuals or legal entities) can establish a company in Turkey. The most common choice is a limited liability company (Ltd. Şti.) or joint-stock company (A.Ş.). Minimum capital requirements and notarised documents are required, and double taxation treaties allow foreign investors to benefit from additional tax advantages.

How do I pay taxes as a freelancer in Turkey?

To pay taxes as a freelancer in Turkey, you must register with the tax office as a self-employed professional. You need to maintain a professional income ledger, issue professional invoices for services, submit quarterly provisional tax returns and an annual income tax return.

When should a startup hire a CPA?

It is recommended to work with a professional CPA from the moment of company formation. Setting up the correct accounting infrastructure from the start facilitates investor due diligence, cap table management and tax planning down the line.
