What is the deadline for filing my Wisconsin state taxes?

Asked a year ago
The deadline for filing your Wisconsin state taxes is generally April 15th of each year. However, if April 15th falls on a weekend or a holiday, the deadline is extended to the next business day. It is important to note that this deadline applies to both filing your tax return and paying any outstanding tax liabilities you may have. If you are unable to file your taxes by the deadline, you can request an extension until October 15th. However, please be aware that an extension to file does not grant an extension to pay any taxes owed. To avoid penalties and interest, it is recommended to file your taxes and pay any outstanding amounts by the original due date of April 15th.
