Sharply falling tax revenues across the  US have left states facing fresh budget shortfalls and threatening further  painful spending and service cuts following previous multiple rounds  of belt-tightening.
In the first quarter of the calendar  year, tax collections dropped by 11.7 per cent, the largest fall on  record, according to the Rockefeller Institute of Government. Of 50  states, some 45 reported declines.
Early figures for April and May show  an overall decline of nearly 20 per cent for total taxes, “a further  dramatic worsening of fiscal conditions nationwide”, says the institute.
 
Billions of dollars of federal stimulus  funds, combined with cuts to state employee jobs, school districts,  healthcare and even the US prison system, have so far failed to close  the budget gaps.
“The states are constantly trying to  recalibrate their budgets to deal with a shrinking revenue base,”  said Susan Urahn, managing director of state policy initiative at the  Pew Center on the States.
