About us
Two of our partners are independent auditors. Our team that keeps your monthly accounts therefore knows what is examined in an audit and organises your records accordingly. On legal matters we work with specialist lawyers.
How we work
When you change accountants, we handle the handover. Your affairs are not disrupted, even during a filing period.
We listen to you about your business, your field of activity and your current accounting arrangements. The meeting is free of charge and can take place at our office, by phone or online.
We prepare a written proposal based on document volume, number of employees and scope of services, and sign a service contract in line with professional regulations.
We handle the handover of books and documents from your previous accountant, the e-filing authorisations and the e-document settings. If a new company is being formed, we take on the formation procedures.
We receive your documents regularly every month. We file returns without waiting for the last day and inform you of the tax assessed.
Our articles on tax, social security and company law are published in Turkish. Blog · Doing business in Turkey: a guide for foreign investors
FAQ
Questions not answered here can be discussed by phone or at our office.
First, a service contract is signed with your new accountant (mali müşavir), and the contract with your current accountant is terminated in writing. The books, documents and electronic records are taken over with a handover report, and the authorisations in the tax office, e-filing, e-ledger and social security systems are transferred to the new accountant. The change can be made in the middle of a period, but it must be clear from the outset who will file any returns still outstanding. We plan and follow these steps on your behalf; for details, you can reach us via our contact page.
A certified public accountant (serbest muhasebeci mali müşavir, SMMM) is a professional licensed under Law No. 3568 after completing the traineeship and examinations, who can provide advice on financial matters in addition to keeping books. The person called a "bookkeeper" in everyday language does not always hold this title. The person who signs your tax returns and represents you before the tax administration must be a licensed professional. Our founding partner has worked as an SMMM since 2003.
The core scope is keeping the books, preparing and filing tax returns, payroll and social security notifications, and tracking statutory deadlines. Tax planning, how regulatory changes will affect you, responses to official letters and financial reporting for management are also part of the advisory work. The scope is set out in writing in the contract according to the needs of your business. For more information, see our accounting and bookkeeping service.
The fee is based on the type of business (sole proprietorship, limited or joint stock company), the number of documents per month, business volume, the number of employees and the scope of the services you want. Additional work such as foreign trade, VAT refunds, a multi-branch structure or reporting in a foreign language is also taken into account. There is therefore no single price that fits everyone. If you send us your details using the request a quote form, we will prepare an assessment specific to you.
Yes. The minimum fee tariff published for each period by the professional body (TÜRMOB) sets the lowest fees professionals may charge, and fees below this tariff cannot be charged. The tariff distinguishes amounts by type of business and scope of service. The proposal we give you is prepared in line with the tariff applicable for the relevant year.
