How many taxpayers are there in the US?

Answer 1

For tax year 2005, 134,372,678 individual tax returns were filed. Of those filed, 99,880,223 actually had a tax liability and actually paid taxes.

just one corporation (Exxon Mobil) in 2004, pays as much in taxes ($27 billion) annually as the entire bottom 50% of individual taxpayers paid in 2004 (most recent year available), which is 65,000,000 people!

this is for 2004 without the withdrawl of tax payers who did not pay taxes
