There’s some advice for folks who won’t make the tax filing deadline. Stephanie Marquis with the Wisconsin Department of Revenue says, if you’re not going to make the deadline of midnight Tuesday, there’s still time to get an extension from the IRS. “When you have an extension you actually have until October 15th to file your state income tax return, and to pay your taxes without penalty,” Marquis said.
Once you file for a federal extension, you automatically get one from the state as well. You’ll get one percent interest tacked on to any money you owe, unless you file an estimated tax form, which you can find on the department’s web site. Marquis said every year, about 100,000 of the state’s approximately three million tax filers request an extension.
