Abstract: During 2013–2016, there are policy changes on Personal Income Tax (PIT) exemption, stated in PMK No.162/PMK.011/2012, PMK No. 122/PMK.010/2015, and PMK No. 101/PMK.010/2016. Nonetheless, there is no empirical study yet, to my knowledge, that evaluates this policy. An increase of PIT exemptions can be viewed from distributive aspect, of how the incidence (benefit) distributed across taxpayers’ disposable income, as well as on the efficiency aspect, whether it has or has not affected labor supply. This study explored on the efficiency aspect. The agents – taxpayers as workers – now may experience an increase in net income due to a more generous exemption, and whether the policy of PIT exemption may in?uence taxpayers’ labor supply is more of an empirical question. I use SAKERNAS data from 2010–2018 and estimation model is limited to only consider paid (labor) employment rather than self-employment. On paid (labor) employment, firms function as withholding that can extract some of PIT from employee’s salary, and thus paid (labor) employee may then file PIT return. My preliminary result shows that effect of PIT exemption policy change is heterogenous across group of population. PIT exemption expansion increases labor supply of paid (labor) employees of the previously lowest income bracket of PIT. However, although to an extent tax saving may be higher for middle to high income individuals, taxpayers referring to individuals in income bracket of 15% rate tend to be not affected by the policy of PIT exemption.
