It is chiefly the influence of taxes on the income level and on the general level of prices, which by far determine the consumptive abilities of households. The effect of a selective character embraces preferences (more often than sanctions) towards specific directions of consumption. In the conditions of market economy, consumers’ decisions are taken for the most part according to market principles, while public authorities can pursue certain choices of consumers as well as protect certain areas of consumption by adequately shaping specific tax solutions. One should emphasise the objective character of taxes: public authorities concentrating upon the fiscal tasks of taxes does not mean that tax will no longer be an instrument of a redistributive role. Therefore, even when public authorities resign from using tax as an instrument stimulating some desired behaviour of the tax-payers (selective effect), these authorities should consider the non-fiscal effect of applying specific tax constructions (general effect) and assess them in the context of the realised or declared policy.plArtykuł
