Accounting, Filing and Auditing Requirements
The tax assessment period is the calendar year. The corporate
taxes in Turkey are assessed on an annual basis, but the advance
payment is required in quarterly installments (in May, August,
December and February).
A final tax return generally must be filed by 25 March of the
following year. Fines are imposed for unauthorized late
payments.
Employers are responsible for the withholding tax on
remuneration paid to their employees. The tax must be withheld on a
monthly basis for all employees.
