Taxation means levying taxes to generate government income to fund programs and services for citizens. There are two types of taxes - national taxes collected by the Bureau of Revenue, and local taxes collected by cities/municipalities. The TRAIN Law aims to simplify the tax system and make it fairer by exempting low income earners from income tax, taxing lotto/PCSO winnings over 10k at 20%, and setting flat donor's tax and estate tax rates.
