Purpose This study is the first attempt to analyze the effectiveness of recent two major tax policies, the reductions in personal and corporate income taxes and a rise in indirect tax and their combine, under both balanced and unbalanced budget conditions, on the economy and social aspects of Malaysia. Design/methodology/approach This study uses a computable general equilibrium model to investigate the impacts of all simulation scenarios on the key macro and micro indicators. Further, based on the 2012 Malaysia Household Income and Expenditure Survey, it uses a micro-data with a significant number of households (over 56,000 individuals) to analyze the impacts of tax policies on poverty and income inequality of Malaysian. Findings Simulation results show that, under the balanced budget condition, personal and corporate income tax reductions increase economic growth, household consumption, and investment, while the rise in indirect tax has adverse impacts on these variables. However, in the unbalanced budget condition, all tax policies, except indirect tax policy, reduce real GDP and investment in the economy and the indirect tax policy has insignificant impacts on all indicators. All policy reforms reallocate resources, especially labor, in the economy. In both budget conditions, the reductions in corporate and personal income taxes, particularly the corporate income tax, decrease poverty level of Malaysian households. Results also indicate that both tax policies are unable to influence income inequality in Malaysia. Social implications This study recommends that the government can increase its revenue by increasing indirect taxes as it does not have any impact on household welfare. In order to increase government revenues, initial increases in personal and corporate income taxes are suggested as they may have small negative impacts on the economy and welfare of households. Originality/value One of the significant features of this paper is that it examines both expan
