The Assessor's Office checks to make sure that the State Aid to Education Property Tax Credit, known as the Homeowner Rebate, is applied to qualified properties.

When we have reason to believe a property that is currently classified as a primary residence is a secondary residence or a rental property, we mail a letter asking the property owner why the property should remain classified as a primary residence.
If the owner fails to respond within 30 days, we mail a final notice to request the information. If the owner fails to respond within 15 days, the property is automatically reclassified as a Class 4 proeprty, which cannot receive the tax credit, and sent a letter notifying the owner of the change. In addition, we notify the Maricopa County Treasurer's Office which will assess a civil penalty against the property owner that is equal to the amount of the State aid to Education Property Tax Credit given to the property in the prior year.

The property owner may appeal this decision within 30 days to the Maricopa County Board of Supervisors. In determining the reclassification of a property as a primary residence, the Assessor's Office requires documentation that verifies the time of residency.

Acceptable documentation includes:

• Driver's license
• Voter registration
• Copy of income tax return (only name and address section) and motor vehicle registration

We review documentation to establish the dates of residency. For example, we use the issue date of the driver's license with the property address to determine the year or years the reclassification is applicable.

Generally, the date of issuance of the license is adequate proof of residency for that time period. However, with recent changes in the federal travel identification rules, new driver's licenses are being issued. These newly issued licenses do not verify residency for prior years; therefore, additional documentation must be submitted.

The Legal Class Verification Process was created by 42-12052. Review and Verification of Class Three Property; Civil Penalty; Appeals.

• The owner of the property has changed.
• If there has been a change in use
• The owner has a mailing address outside the county in which the property is located.
• The owner has a mailing address, other than a post office box, that is different than the situs address of the property.
• The owner has the same mailing address listed form more than one parcel of Class Three property in this state.
• The owner appears to be a business entity.

If the assesor has reason to believe that a parcel of property that is classified as class three pursuant to section 42-12003 is not the owner's primary residence or as a qualifying family member residence pursuant to section 42-12053, the assessor shall notify the owner, in a form prescribed by the department as provided by subsection D of this section, and request that the owner respond as to whether the property meets the requirements of section 42-12003 or 42-12053, is a secondary residence or is used as a rental property.

If the owner fails to respond to the assessor within 30 days after the notice is mailed, the assessor shall mail the owner a final notice within 30 days requesting that the owner provide information as to whether the property meets the requirements of a primary residence, a secondary residence or is used as a rental property. If the owner fails to respond to the assessor within 15 days after the final notice is mailed, the assessor shall reclassify the property as Class 4.

There is no need to return the notice if the owner fails to do so by the deadline. The assessor will mail a final notice that the owner has 15 days to complete before their property is reclassified as a Class 4.

If the owner fails to respond to the assessor within 30 days after the First Notice is mailed, the assessor shall mail the owner a Final Notice of Intent within 30 days requesting that the owner provide information as to whether the property meets the requirements of a primary residence, a secondary residence or is used as a rental property.

No, appeal the Notice of Reclassification that you will receive in the mail.

The owner of the property that is reclassified as Class 4 under this paragraph may appeal the reclassification to the Maricopa County Board of Supervisors within 30 days after the notice of classification is mailed. If the owner proves to the board’s satisfaction that the property is occupied as the owner’s primary residence, the board shall order the property to be reclassified as Class 3 property pursuant to section 42-12003.
