Change in Filing Dates for Returns Due in 2011
Filing Due Date is April 18, 2011 for Wisconsin
District of Columbia Emancipation Day, which is generally celebrated April 16, is a legal holiday for federal tax purposes. When April 16 falls on a Saturday, the holiday is celebrated on Friday in the District of Columbia. Therefore, April 15, 2011, is a federal legal holiday.
Generally, if a due date for performing any act for tax purposes falls on a Saturday, Sunday, or legal holiday, the time to perform such act is delayed until the next day that is not a Saturday, Sunday, or legal holiday. Because April 15, 2011, is a Friday, the date for performing certain acts is April 18, 2011. As a result, federal returns that originally had a due date of April 15, 2011, will be considered timely filed if filed on or before April 18, 2011.
The delay in the filing date until April 18, 2011, also applies for Wisconsin tax purposes. The following actions qualify for the new April 18, 2011, deadline:
- Calendar-year 2010 Wisconsin individual income tax returns, whether filed electronically or on paper (Forms 1, 1A, WI-Z, and 1NPR).
- Tax-year 2010 balance-due payments, whether made electronically (online, direct debit, or credit card) or by check.
- For calendar-year taxpayers, individual estimated tax payments for the first quarter of 2011, whether made electronically or by check. In rare cases, estimated tax payments for the second, third, and fourth quarters may be affected for individuals operating on a fiscal year that is not a calendar year.
- Individual refund claims for tax year 2006, where the regular four-year statute of limitations is expiring.
- For calendar-year taxpayers, tax-year 2010 contributions to a Roth or traditional IRA.
