Policymakers seek the equilibrium between generating tax revenues and preserving labor market participation, but the nonlinear effects of tax policies on labor supply elasticity and revenue efficiency are not yet well understood. Employing a multi-step regression model on a two-decade cross-country panel data set, the research introduces RL algorithms to maximize tax rates and welfare spending. The findings present a nonlinear, inverted-U-shaped Laffer Curve with higher tax rates raising revenue at the beginning but decreasing employment and revenue thereafter. Public spending on complements like childcare and eldercare offsets the disincentive effects of taxation on work, highlighting the need for coordination between taxation and social policy. The RL-based optimization more precisely improves tax policy suggestions, providing a model for balancing social spending and tax rates in order to improve fiscal discipline and labor market durability in post-reform economies. This research offers important information for policy design so that tax systems are not only efficient but also equitable.
