What Is Withholding and Premium Service Declaration (Muhtasar ve Prim Hizmet Beyannamesi)?
The Muhtasar ve Prim Hizmet Beyannamesi is the combined return through which employers in Türkiye report income tax withheld at source together with employees' social security premium and service data.
The return was created by merging the former withholding tax return with the monthly premium and service document, so that reporting to the tax administration and to the Social Security Institution now travels in a single filing.
Reportable payments include wages, professional service fees, rent and the other payments on which legislation requires withholding. The same return also declares employees' working days, earnings and any premium incentives claimed.
Because the two data sets are combined, tax and social security records can be cross-checked automatically. Inconsistencies between wage reporting and premium reporting surface within the system, which puts a premium on internally consistent payroll data.
Filing periods and the payment calendar are set by legislation and updated from time to time. For foreign-owned companies the practical point is that payroll in Türkiye is not simply a payment run but a recurring, auditable declaration process.
