Workers at the Wisconsin Department of Revenue are busy processing returns, but half a million Americans still haven't filed their taxes.
About 2/3 of filers now file on line and experts say if you do file on line, you can get your return in as little as 3 days.
"We're now in the crunch time. If you paper file and you're expecting a refund, it's going to be anywhere from 3 to 5 to 8 weeks. It's a lot longer," says Meredith Helgerson with the Wisconsin Department of Revenue.
The deadline for filing this year is Monday, April 17th.
If you paper file, it must be postmarked by 11:59 p-m.
