2TaxationTaxationApril 15thhas largely become one of the least favorite days of the year for many Americans. This is because it historically has been the deadline for filing your taxes with the United States (US) government. Many people do not realize the impact that the taxes we pay outside of the annual IRS filing have. Taxes in general have an enormous impact on spending notonly in the US but across the globe. This paper will examine how taxation and spending impact public policy. According to Schalteggera and Torgler (2006), when measuring the amount of gross domestic product (GDP) that goes to government expenditures most industrialized countries have expanded the size of their governments. Since 1960, member countries of the Organization for Economic Cooperation and Development (OECD) have grown their governments by more than twenty percent. In OECD countries nearly fifty percent of GDP is accounted for by government expenditures. Those who disapprove of this large government expansion argue that it negatively impacts economic wellbeing.
