In Estonia, there is no corporation tax on undistributed profit. In other words, if the profit stays in business, you won’t have to pay taxes on it.
If the profit is somehow distributed among the partners, the corporation tax will be paid under the so-called 20/80 scheme: 20% of the profit will go to the state budget while 80% will be dividends. If you meet a number of requirements, you will also be able to reduce the tax rate to 14%.
Besides, Estonia has signed a number of double taxation agreements, so you will be able to pay corporation tax only in the country where your company operates. There is a reduced or even zero VAT rate for many goods and services.
