state income tax revenue fell not only because of lower wages and salaries, but also due to tax evasion.

in spite of the global recession, US income tax collections have shown a modest increase in states like California and Vermont.

income tax withholdings bear no relationship to citizens' wages and salaries.

income tax is not the only source of state revenue, but the major one.

although most American sates experienced considerably lower personal income tax collections in the first four months of 2009, predictions are that they will have fully recovered by 2011.
