If you are an Arizona resident veteran with a total and permanent disability rating from the VA, your property is completely exempt from property tax. The rating can be service-connected or non-service-connected. If your rating is less than 100 percent, you get an exemption of up to $4,748 of your assessed value: multiply $4,748 by your VA disability percentage to find your amount, and the total assessed value of the property must not exceed $36,454. Your total income must be no more than $39,865, or no more than $47,826 if you have minor children or children with a disability. An unremarried surviving spouse of a deceased disabled veteran also qualifies.
Property tax in Arizona is administered by county assessors, not the state. Contact the assessor in the county where your property is located to apply and to confirm their filing window.
If you are the veteran: your DD214, proof of Arizona residency, a VA Benefit Summary Letter, and proof you meet the income limits. If you are the surviving spouse: the death certificate, proof of Arizona residency, and proof you meet the income limits.
