NASHVILLE, Tenn. (AP) - The Internal Revenue Service reminds an estimated 169,000 Tennesseans that their six-month extension for filing their 2010 federal tax returns ends Monday.

The IRS said in a news release Thursday that individuals and small businesses should double check their returns for recently expanded tax benefits such as the new Small Business Health Care Tax Credit.

Meanwhile, the agency said that more than 2.2 million Tennesseans have used IRS e-file so far this year, up about 14% over last year.
