The

has around $760 million in unclaimed refunds from taxpayers who qualified and didn't file returns in 2010. But time is running out to get your hands on that cash.

Folks who didn't file that year have until April 15 to file a Form 1040 – without a penalty -- to receive their refund. And it's not chump change. The median for the unclaimed refunds is $571.

In Oregon, about 14,300 taxpayers didn't file returns in 2010, the IRS reported, leaving $10.36 million on the table. If unclaimed, that money goes back to the government after April 15. The median for Oregon refunds is $519.

Oregon isn't amongst the highest with return slackers. California takes that top spot with about 86,500 residents who didn't file in 2010 and stand to receive around $$69.75 million. Nationwide, around 918,600 taxpayers didn't file returns in 2010.

John Koskinen, the new IRS commissioner, visited Portland on Wednesday as part of a national tour. He said many of those who didn't file in 2010 likely figured they hadn't made enough to qualify, such as students or part-time workers.

To be clear, taxpayers who haven't filed for 2011 or 2012 may have those older returns held. They'll also be held if taxpayers owe the feds.

Taxpayers who have questions or can't figure out if they filed in 2010 can call the IRS at 800-829-1014.
