A general equilibrium model is established to evaluate fiscal policy in Taiwan, particularly the replacement of the sales tax by a value-added tax. To begin, the major taxes levied in Taiwan are identified and briefly described. Based on this descriptive analysis, we can make assumptions concerning tax incidence for Taiwan's major taxes within a general equilibrium framework; and the effective tax rates, by type of tax, by family income class, are calculated. Then, a general equilibrium computation algorithm is applied to convert an abstract representation of an economy into an operational model The results are obtained by comparing the solutions between before- and after-tax equilibrium in nonlinear equations system. The main conclusions show that (1) the relative prices of goods, in general, only have a small change; and (2) the efficiency gain in production and total welfare gain are both small as well
