Individual Income Tax
- What is the deadline for filing my Wisconsin return?
Your 2013 return must be filed by April 15, 2014, unless you request an extension of time to file.
A paper return is considered filed by the due date if all three of the following conditions are met:
- the return is mailed in a properly addressed envelope with the postage duly prepaid,
- the envelope containing the return is postmarked on or before the due date, and
- the return is received by the Department of Revenue within 5 days of the due date.
If you file late, without an extension, you are subject to penalties and interest.
For information on obtaining a Wisconsin extension of time to file, see the Extensions for Paper and Electronically Filed Returns Common Question.
