Revenue Steadily Increasing
Government revenue in the United States steadily increased
from $1.3 trillion in the mid 1980s to $3.7 trillion in 2000. But its steady increase
was impacted in the recession of 2000-01 and the Great Recession of 2008-09.
Chart 3.11:
Government Revenue in dollars
Government revenue amounted to $1.3 trillion in the mid 1980s, and then breached
$2 trillion in 1992 just after the recession of 1990-91. In the 1990s revenue increases accelerated, reaching $3.2 trillion in 1998 and reaching a peak of $3.7 trillion in 2000. But in the 2000s, with the dot-com crash and 9/11,
government revenue declined hitting $3.3 trillion in 2002 before resuming its increase again. Revenue reached above $4 trillion in 2005 and $5 trillion in 2007.
Then came the Crash of 2008 and government revenue nose-dived down to $3.6 trillion in 2009. After a few years of catch-up, revenue is expected to breach $6 trillion in 2015.
Chart 3.12:
Government Revenue as Percent of GDP
Viewed as a percent of Gross Domestic Product (GDP) government revenue in recent years has
fluctuated. Starting at 32 percent of GDP in 1985, revenue increased slightly to 33 percent of GDP through the mid 1990s.
Then revenue began an increase in the boom of the late 1990s, reaching 37.2
percent of GDP in 2000. Revenue retreated to 31.2 percent of GDP in the trough of the 2000-01 recession, before increasing back to 37 percent of GDP at the business cycle peak in 2007.
In the Crash of 2008 government revenue decreased sharply. Revenue declined to 26 percent of GDP in 2009. But revenue is expected to recover to about 35 percent of GDP in the next few years.
Recent Revenue by Government Level
Federal revenue as a percent of GDP has shown a decline in recent decades.
But state and local revenue have increased.
Chart 3.13:
Government Revenue by Level
Federal revenue stood at 17.4 percent of GDP in 1985. State government
revenue was 8.3 percent of GDP and local revenue was 6.3 percent of GDP.
By the year 2000 federal revenue had increased to 20.5 percent of GDP, but state revenue
had increased to 10 percent of GDP and local revenue had increased to 6.7 percent of GDP.
In the 2000-01 recession federal revenue decreased to 17.5 percent of GDP by 2002, state revenue had decreased sharply to 7.2 percent of GDP and local revenue had decreased
modestly to 6.5 percent of GDP. In the recovery, federal revenue increased to 18.4 percent
of GDP by 2007, state revenue had increased sharply to 11.2 percent of GDP and local
government revenue had increased modestly to 7.4 percent of GDP.

Then came the Crash of 2008. In 2009 federal revenue dropped to 15 percent of GDP,
state revenue collapsed to 4.5 percent of GDP (including $0.5 trillion in employee pension
fund losses) and local revenue decreased to 6.4 percent of GDP. By 2015, federal revenue is
projected to increase to 19 percent of GDP, state revenue to 9.5 percent of GDP and local revenue to 7 percent of GDP.
Revenue by Type
Income tax revenue fluctuates; ad-valorem taxes do not.
Chart 3.14:
Total Recent Revenue by Type
In 1992 income taxes at all levels of government collected 11.3 percent of GDP; social
insurance taxes collected 7.4 percent of GDP. Ad-valorem taxes, such as sales and property
taxes, collected 7.9 percent of GDP. Fees and charges totalled 2.2 perent of GDP and business
revenue totaled 4.4 percent of GDP.
At the top of the business cycle in 2000, income taxes collected 14.8 percent of GDP, social
insurance taxes collected 7.2 percent of GDP and ad-valorem taxes collected 7.6 percent of GDP.
Fees and charges totalled 2.3 percent of GDP and business revenue totalled 5.3 percent of GDP.
At the top of the business cycle in 2007, income taxes collected 13.5 perent of GDP and
social insurance taxes amounted to 6.9 perent of GDP. Ad-valorem taxes totalled 7.6 percent
of GDP. Fees and charges totalled 2.5 perent of GDP and business revenue totalled 6.5
percent of GDP. Two years later in the depths of the Great Recession income taxes had
declined to 9.8 percent of GDP and social insurance taxes had increased to 7.1 percent of GDP.
Ad-valorem taxes were almost unchanged at 7.7 percent of GDP. Fees and charges increased
to 2.8 percent of GDP and business and other revenues had gone negative to -1.4 percent
of GDP, primarily due to $0.5 trillion in losses on government employee pension plans.
By the mid 2010s income taxes are expected to increase their take to 13.1 percent of GDP, and
social insurance taxes will be about 6.8 percent of GDP. Ad-valorem taxes will increase
to 7.4 percent of GDP, fees and charges will increase to 2.6 percent of GDP and business revenue
will increase to 4.7 percent of GDP.
Revenue Breakdown by Level of Government
The federal government raises revenue principally from income and social insurance taxes. State
government revenue breaks down about equally between income taxes, ad-valorem taxes, and fees and business revenue. Local
government revenue is about half ad-valorem taxes and half fees and business revenue.
Chart 3.15:
Federal Revenue in Recent Decades
In the last 25 years, since the 1990s, federal revenue has come principally from income taxes,
individual and corporate. Individual income tax in 1985 yielded 7.9 percent of GDP and
the corporate income tax yielded 1.45 percent of GDP.
By the top of the late 1990s boom
the individual income tax was yielding 10.2 percent of GDP and the corporate income tax
was collecting 2.1 percent of GDP. But by the end of the 2000-01 recession in 2003
the individal income tax had collapsed to 7.2 percent of GDP and the corporate income tax
take was cut almost in half to 1.2 percent of GDP.
At the top of the mid 2000s boom the individual
income tax collections had increased in 2007 to 8.3 percent of GDP and the corporate income
tax had increased to 2.65 percent of GDP. In 2010 in the depths of the Great Recession the
individual income tax collected 6.2 percent of GDP and the corporate income tax collected
1.32 percent of GDP.

- Individual Income Tax

- Corporate Income Tax

- Social Insurance Tax

- Ad-valorem Tax
The next largest tax source for the federal government comes from social insurance taxes like
the FICA tax on wages. It fluctuates much less than the income tax. In 1985 social
insurance taxes collected 6.3 percent of GDP and had increased modestly to 6.6 percent
of GDP just before the 1990-91 recession. In the 1990s boom social insurance taxes collected
between 6.4 and 6.6 percent of GDP. In the 2000s social insurance taxes started out in 2001
at 6.8 percent of GDP then declined to 5.95 percent of GDP in 2010. Social insurance tax collections
dropped to 5.4 percent in 2011 and 2012 when the federal government cut the FICA tax rate for two years.
Social
insurance tax collections are expected to increase back over 6 percent of GDP by the mid 2010s.
Other revenue sources amount to about 1 percent of GDP.
As the chart shows, the yield from income taxes fluctuates with the economy, and the
fluctuation has been getting worse with the dot-com recession of 2001-02 and the Great Recession of 2007-09.
Chart 3.16:
State Revenue in Recent Decades
State revenues in the last quarter century have come principally from three sources: income
taxes, ad-valorem taxes such as property and sales taxes, and business revenue. Income taxes
collect from 2.0 to 2.3 perent of GDP, social insurance taxes collect about 0.6 to 0.8 perent of GDP. Ad-valorem taxes yield in the rage of 2.9 to 3.3 perent of GDP, and fees and charges
have increased from 0.8 percent of GDP in 1992 to 1.1 in 2010.
As the chart shows, the revenue from business income fluctuates with the economy. This is
primarily driven by gains and losses in state employee pension funds. In a good year,
business income can reach 4 percent of GDP. In 2009, after the Crash of 2008, business
income was -2.5 percent of GDP.
Chart 3.17:
Local Revenue in Recent Decades
Local revenues have remained principally ad-valorem taxes, ranging from 3 to 3.8 percent
of GDP. Income taxes remain negligible in most localities. Fees and charges range from 1.3
to 1.6 perent of GDP. Business income, including employee retirement operations, account for revenue ranging from 1 to 2 percent of GDP.
