A hot economy continues to slosh oceans of cash around Georgia, as the latest tax receipts from state government show. Tax revenue is up almost $1 billion compared to this time last year, according to Gov. Nathan Deal’s office. As of May, net tax collections for the year totaled $20.73 billion — a full $940.8 million more than the same period in 2017. That’s an increase of 4.8 percent.
