How much is the Flat Tax in Bulgaria and how does it work?

Bulgaria’s Flat Tax is 10%. But, 10% of what?

For local companies, the tax is 10% of the income generated within Bulgaria and abroad, after deductions. For foreign-owned corporations, the tax is 10% of the income produced from commercial activities within the territory of Bulgaria, after deducting business expenses. 

10% is also the rate of personal income, regardless of the amount. 

Corporate income tax is applied to companies registered under Bulgarian law, but also non-resident companies generating income within the country limits.

The tax year in Bulgaria is equal to the calendar year, with the responsibility of filing taxes by the 31st of March of the following year.

If corporate income is under BGN 300,000, no prepayments are required. With corporate income above that threshold, corporate tax is deducted in advanced installments.

Newly Bulgaria companies registered do not need to pay taxes on the year of incorporation.

History of Bulgaria Flat Tax

Bulgaria went through a financial crisis during the 90s. During the early years of this decade, Bulgaria transitioned from a closed socialist economy to a democracy, and with it came an open market economy, accompanied by very high taxes that in some cases piled up to more than 50%.

In the last 25 years, Bulgaria underwent a transformation of the whole tax system, going from steep taxation to a flat rate of 10%. And the changes worked. 

It was quickly proven that a lower tax meant a steadier income for the government and less tax evasion. In more recent years, Bulgaria is trying to capitalize on this reputation, promoting an optimistic business environment, creating regulations that attract foreign companies, and keeping the flat tax rate, overall, making Bulgaria an attractive tax haven in Europe.
