This paper examines Act 32 of the Pennsylvania state legislature which mandated the introduction of withholding for the local earned income tax (EIT) for all employees and the consolidation of a fragmented collection system to one collector per county effective January 1, 2012. The estimates I obtain suggest that the act resulted in increased compliance with the EIT of about 13 percent. A falsification exercise examining compliance with the property tax for the identical municipalities confirms that Act 32 did not impact the property tax. Both findings are robust to the inclusion of municipality fixed effects or municipality-specific time trends.
