Tax Deadline Two Weeks Away

The tax filing deadline is two weeks away and the Wisconsin Department of Revenue is reminding taxpayers to file their income tax returns by the deadline. Returns must be received or postmarked by midnight on Tuesday, April 18. The deadline is extended this year because April 15 is a Saturday and Monday, April 17 is a holiday in Washington, D.C. The Department of Revenue is sharing the following tips to make the filing process easier:
  • Use our self-service options. Use links to income tax forms and instructions or find answers to common questions about preparing your tax return, tax credits and much more.
  • Pay your taxes online. The department offers easy of your taxes on its website.
  • File an extension request with the IRS if you won’t make the April 18 deadline. You must request an extension from the Internal Revenue Service (IRS) by April 18 to avoid late filing penalties. Go to the IRS website and search “extension” for more information. Taxpayers who file an extension request with the IRS automatically receive an extension from the state. Keep a copy of the IRS federal extension application (Form 4868) for your records.
