This tax filing season, donors can no longer “look for the loon,” the traditional slogan referencing the icon in the donation section of the Wisconsin income tax form to aid filers in gifting a portion of their tax return to the state Endangered Resources Fund.

Although donations through the tax check-off program can still be made, this year’s message asks donors “Where did the loon go?” because recent legislation removed all such icons from the tax forms.

The program preserves and manages more than 200 endangered and threatened Wisconsin plants and animals, as well as some of the state’s remaining examples of prairies, forests and wetlands.

Private donations account for 25 percent of the funding received by the program. Each dollar contributed through the tax check-off, or through a direct donation, is matched by a state dollar up to $500,000.

To donate through the tax check-off, look for the “Donations” area on Wisconsin income tax forms. Specifically, look for Line 37a on Form 1, Line 27a on Form 1A and Line 14a on Form WI-Z.
