Advance corporate tax in Bulgaria: complete guide

 To open a company in Bulgaria means gaining access to a competitive tax regime and an attractive environment for investments. However, those who decide to operate in the country must also understand certain specific aspects of Bulgarian taxation, including the advance corporate tax, which represents a prepayment of corporate income tax.

This mechanism can significantly affect cash flow and financial planning, making it essential to know its rules and implications.

Meaning and purpose of advance corporate tax in Bulgaria 

In Bulgaria, companies are sometimes required to make tax payments during the year rather than paying the entire corporate income tax only at year-end. Advance corporate tax represents a prepayment of the annual liability, calculated on the basis of projected profits for the current year, using the previous year’s results as a reference.

The main purpose of this system is to secure more regular tax revenues for the state while distributing the companies’ tax burden throughout the year instead of concentrating it in a single annual payment.

Advance corporate tax in Bulgaria: which businesses are required to pay

Not all companies fall under this obligation. The decisive factor is the turnover from the previous financial year:

• Revenue below 300,000 BGN → no advance corporate tax is due; payment is made only with the annual return.
  
• Revenue above 300,000 BGN → advance payments are mandatory, on a quarterly or monthly basis depending on the company’s size and expected profit.
  

This means that newly established companies with modest turnover may not be required to make advance payments, while more established businesses must plan their cash flow carefully to meet periodic obligations.

Advance corporate tax in Bulgaria: how the installments are calculated and adjusted

The calculation of advance corporate tax is based on profit forecasts. In practice:

• the company’s previous year financial results are used as a reference;
  
• estimated profit for the current year is determined;
  
• the tax liability is calculated and split into advance installments.
  

At the end of the financial year, advance payments are reconciled with the actual tax due:

• if the company overpaid, the excess is refunded or carried forward;
  
• if the company underpaid, the difference must be settled within the legal deadlines.
  

This ensures a final alignment between prepayments and the actual tax liability but requires precise bookkeeping and reliable financial forecasts.
