Corporation tax is always going to be a race to the bottom. It would be better to accept that and abolish it. Replace it by treating dividends and capital gains as normal income for tax purposes. This would be much harder to avoid.

> However, the system of corporate earnings taxation currently in force in Estonia is a unique system, which shifts the moment of corporate taxation from the moment of earning the profits to the moment of their distribution. In other words, earning profits in itself does not bring income tax liability, which arises only when earned profit is distributed to shareholders.
Sale -> VAT -> Corporate Tax -> Employment and social security taxes -> Dividend and capital gains tax
Also, it is weird that tax in english is used to describe VAT as well as employment/SS "tax", this is not the same thing (or at least it shouldn't be).
Some corporate tax, easely negated by going in debt, is necessary though.
