Get help with your 2016 Tax Return
Are you a low- or moderate-income taxpayer needing help with your 2016 return? Mesa United Way's Volunteer Income Tax Assistance season begins on January 30th 2017. There are six sites open again this year where you can get your 2016 tax return completed by trained, IRS certified tax preparers. The income limit this year is $54,000. Your return will be E-Filed which means that your refund (if you have one coming) will be delivered to your bank account or by check as soon as possible. Please see a map showing the locations in Mesa and the weekly schedule of service times below.
