As I discussed on the FOX Business Network,  the IRS recently saw it’s largest revenue drop in over 30 years. You  can watch  my appearance here, but USA  Today also posted an interesting article on the same subject. You can  find a snippet of their article below, or check out the full post here. 
Federal tax revenue plunged $138 billion,  or 34%, in April vs. a year ago — the biggest April drop since 1981,  a study released Tuesday by the American Institute for Economic Research  says.
When the economy slumps, so does tax  revenue, and this recession has been no different, says Kerry Lynch,  senior fellow at the AIER and author of the study. "It illustrates  how severe the recession has been."
For example, 6 million people lost jobs  in the 12 months ended in April — and that means far fewer dollars  from income taxes. Income tax revenue dropped 44% from a year ago.
 
"These are staggering numbers,"  Lynch says.
Big revenue losses mean that the U.S.  budget deficit may be larger than predicted this year and in future  years
"It's one of the drivers of the  ongoing expansion of the federal budget deficit," says John Lonski,  chief economist for Moody's Investors Service. The Congressional Budget  Office projects a $1.7 trillion budget deficit for fiscal year 2009.
 
The other deficit driver is government  spending, which, the AIER's report says, is the main culprit for the  federal budget deficit.
The White House thinks that tax revenue  will increase in 2011, thanks in part to the stimulus package, says  the report from AIER, an independent economic research institute. But  it warns, "Even if that does happen, the administration also projects  that government spending will be so much higher each year that large  deficits will continue, and the national debt held by the public will  double over the next 10 years."
