Because the Bulgarian law still does not allow foreign nationals to own land, the majority of investors are purchasing their properties through a company registered in this country. However having a company is a serious issue and investors must accept seriously the requirements of the tax law, which is quite strict and conservative. During the recent years the tax authorities have become quite active and regular checks are performed with or without a reason. Even if your company is registered just to own a property and not actively trading, it is still subject to control and inspection by the local tax officers.  Each company (including the dormant ones) is obliged to prepare an annual tax report for its business activities and submit it to the local tax office before 31st March each year. The fines for not submitting the annual tax declaration on time start from 500 Levs (approx. 250 Euros).  For dormant companies (registered only to own a property), or companies without any activities we charge an annual fee which will cover the annual tax report and submission to the local tax office.
If your company is operational the charge is paid monthly and is subject to additional negotiation, depending on the amount of work required.
