Tax is collected mainly from municipal income tax, state income tax, state value added tax, customs fees, corporate taxes and special taxes. There are also property taxes, but municipal income tax pays most of municipal expenses. Taxation is conducted by a state agency, Verohallitus, which collects income taxes from each paycheck, and then pays the difference between tax liability and taxes paid as tax rebate or collects as tax arrears afterward. Municipal income tax is a flat tax of nominally 15-20%, with deductions applied, and directly funds the municipality (a city or rural locality). The state income tax is a progressive tax; low-income individuals do not necessarily pay any. The state transfers some of its income as state support to municipalities, particularly the poorer ones. Additionally, the state churches - Finnish Evangelical Lutheran Church and Finnish Orthodox Church - are integrated to the taxation system in order to tax their members.
