An individual pays tax on their income as a wage earner or as a self-employed person. An employer is obligated to deduct on a monthly basis the tax payable on an employee's salary. A self-employed person must prepay income tax that will be offset by filing an annual return.
In Bulgaria there is a 20% flat rate of VAT tax. Foreign visitors are entitled to a refund. VAT returns must furthermore be submitted where there is no payable or refundable tax. The returns must be submitted on or before the 14th day of the month following the tax period to which the returns refer.
