Natural persons and Sole proprietors

According to the Commercial Act, any capable natural person with place of residence in the country can register as sole proprietor (SP). The firm of the sole proprietor must contain without abbreviations the first name and surname as publicly known. Foreign natural persons may only register as sole proprietors in Bulgaria if they have permanent residence in the country.

On the other side, any natural person in Bulgaria who is not registered as sole proprietor and receives income from non-employment relations, fees, earnings from another business activity, etc., undertakes to provide the relevant tax information regarding his/her earnings for the current year before the Bulgarian tax institutions, the deadline being 30th April of the following year.

The correct reporting of the activity of natural persons and sole proprietors (SP) involves work with different types of primary and secondary documents, procedures during incorporation and registration of SP, closing of SP, calculation and payment of social security contributions and taxes, preparation of reports, tax calculations, tax returns and many more.

There are many preconditions giving rise to cases, therefore the accountancy of SP must be entrusted to well-prepared professionals.

The taxation regime for earnings of natural persons, including sole proprietors, is governed by the Natural Persons Income Tax Act (NPITA).
