The Maricopa County Assessor’s office issued its initial 2011 valuation notices at the end of February.  If you wish to file a 2011 administrative appeal on your Maricopa County real property, you must file a petition for review no later than April 13, 2010.  (Please note that the filing deadlines in other Arizona counties are not the same as Maricopa.  For example, the Pima County administrative appeal filing deadline is April 5, 2010.  Therefore, if you have properties in other counties please check your valuation notices to determine that county’s filing deadline.)

If you do not file an administrative appeal, you have until December 15, 2010, to file a 2011 appeal directly with the Arizona tax court.
