HARRISBURG, Pa. (AP) — Pennsylvania is getting an unexpected windfall, as internet sales tax revenues are coming in at a rate of nearly four times what had been projected for the current fiscal year. The state’s revenue department officials say Pennsylvania estimated to collect about $50 million this year from the tax on online transactions, but it’s now looking like about $200 million will be actually remitted. Pennsylvania imposed sales tax on people who use online marketplaces to sell their wares two years ago.
