Net tax collections in Georgia were up 6.4 percent in October, compared to the same month a year ago, Gov. Nathan Deal’s office said Friday.

The increase, of $83.5 million, means state revenues are up 4.8 percent for the first four months of the fiscal year, for a total of $5.6 billion.

Individual income tax collections led the way, rising 8.2 percent or $57.25 million.Sales tax collections, meanwhile, barely kept pace with October 2011, rising just $2 million, or 0.5 percent.

Corporate income taxes, the smaller of the state’s three main pots of income, were up 58.7 percent, although refunds continued to outstrip revenues. Net corporate taxes in October were -$4.01 million.
