Abstract: Under the current system of deferred tax on enterprise annuity, taking the economic entity with no deferred tax as the baseline and introducing the bequest motive and the bequest taxation into the general equilibrium two-period overlapping-generations model, this paper studies the economic effect of how bequest taxation and the changes of its tax rates affecting the system of deferred tax on enterprise annuity, i.e. the equilibrium solution to the problem of how such economic variables as output level, capital stock, wage level, consumption level and so on being affected. The research results show that the policy of deferred tax on enterprise annuity can increase output and at the same time improve the capital stock, decrease the interest rate and at the same time raise the wage level, increase savings and at the same time improve the two-period consumptions, and improve the individual welfare. To levying the bequest tax will weaken the positive effects of the deferred tax on the economy; the higher the tax rate of the bequest tax, the stronger the bucking effect on the deferred tax. When the high tax rate reaches a certain degree, the deferred tax would otherwise lower the level of social welfare.
