The paper addresses the problem of international tax competition in a coexistence of: capital, labor and consumption taxation. We allow for the possibility of capital gains shifting abroad and for the different levels of capital ownership. On this basis, the optimal taxation conditions were derived. Generally, in the case of low capital-marginal–productivity-elasticity, for given level of tax consumption burden, the capital should be subsidized and the labor should be taxed positively. If we exclude the subsidies for capital then the taxation of labor becomes sensitive to both the size of the consumption tax and the level of international income shifting.
