Every three years, Cook County does the triennial reassessment of real estate tax bills.

Notices were just mailed to Barrington township. Evanston township notices were mailed July 15, 2010 and Barrington on July 8, 2010. These will be followed shortly by notices sent to other northwest suburban townships like Palatine, Schaumburg, Wheeling and Elk Grove.

Why does this matter?

Because this will be your only chance to protest your taxes for the next three years, that’s why.

The key thing here is to watch your mail for the reassessment notice because you only have 30 days from the date the reassessment notice is sent to protest your assessment.

The new assessments will affect the 2010 tax bill issued in the Fall of 2011.
