Fiscal Policy

19 January, 2016 - 16:50

For individuals and firms paying taxes in the United States, April 15 is an important day because tax forms are due for the previous calendar year. Each year US citizens fill out their tax forms and either make tax payments or receive reimbursements from the government.

The tax day differs across countries, but the experience is much the same everywhere: individuals and firms must pay taxes to the government. This is one of the key ways in which citizens interact with their governments.

A more complete version of the 1040EZ form for 2010 is shown in Figure 2.4 Form 1040EZ  .

From the perspective of an individual filling out this form, the task is to get the data correct and determine exactly what figures go where on the form. This is no small challenge. From the perspective of economists working for the government, the tax form is an instrument of fiscal policy. Embedded in the tax form are various tax rates that must be paid on the different types of income you earn.

Where do these tax revenues go? The government collects taxes to finance its purchases of goods and services in the economy—such as roads, schools, and national defense—and also to make transfers to households, such as unemployment insurance.

The tax forms we fill out change each year, sometimes quite significantly. The tax rates households and firms confront are changed by governmental decisions. The government alters tax rates to affect the level of economic activity in the economy. It uses these tools when, in its judgment, the level of economic activity (as measured by real GDP, the unemployment rate, and other variables we will learn about) is insufficient. This is a delicate assessment that requires an understanding of the meaning and measurement of satisfactory economic performance and a deep understanding of how the economy works.

For example, consider the winter of 2008. Policymakers working in the White House and on Capitol Hill kept careful track of the state of the economy, looking as we just did at announcements from the BEA and the BLS on output and inflation. Eventually, they concluded that economic activity was not at a high enough level. They took actions to increase output by reducing taxes through the American Recovery and Reinvestment Act of 2009 (http://www.irs.gov/newsroom/article/0,,id=204335,00.html). The idea is as follows: when people pay less in taxes, they have more income available to spend, so they will purchase more goods and services. The link between the legislation and you as an individual is through tax forms like the one shown in Figure 2.4 Form 1040EZ  .
