LANSING — Residents of the 21st state Senate District who are in need of tax preparation information can obtain the 2012 Michigan Taxpayer’s Guide by visiting Sen. John Proos’ website, the lawmaker said Wednesday.

The guide, which is a reference for the 2011 tax year, is designed to help residents prepare their tax returns.

“It is important for residents to have reliable, updated information when preparing their annual taxes,” said Proos, R-St. Joseph. “As your state senator, I am proud to offer this taxpayer’s guide free to all southwest Michigan residents. I encourage everyone to utilize this valuable resource while filling out their 2011 tax forms.”

The booklet contains information on Michigan’s taxes and tax credits. Included is a yearlong taxpayer’s calendar with reference to important tax dates and filing deadlines. Also inside are copies of the most commonly used tax forms, as well as addresses and phone numbers for obtaining state agency tax assistance.
