Tax Revenue, Post-WWII, Averages 17.7 Percent Of GDP

In the years since World War II (1946-2011), federal tax receipts have averaged 17.7% of Gross Domestic Product (GDP). This is probably the best way to gauge the federal tax burden because it compares it to economic output. Since there are many arguments in and out of Washington D.C. about the effects of taxation on economic growth, it makes sense to directly compare the measure of taxation (total federal tax receipts) with the measure of economic output (GDP).
