Property taxes in Arizona fluctuate according to value, but the amount of taxes you owe can also change due to other factors. The assessor can add any changes in your property’s valuation that you make between January 1 and September 30, and these will go into effect for the current tax valuation year, according to the Arizona State Board of Equalization.
Here are some events that may trigger a change in the taxes on your property.
A change in use
Perhaps you are planning to move, but rather than sell your current residence, you want to find a renter, either on a short-term or long-term basis. If so, you must notify the county assessor right away, or you may have to pay penalties. Converting an owner-occupied residence to a rental property causes the loss of the Homeowner’s Rebate, which will increase the amount of taxes you will owe.
Improvements or other changes
If you want to add on a new master bedroom and bathroom to the back of the house, build an addition over the garage or start some new construction project on the property, it will increase the value of the property and the amount of taxes you pay. Even a demolition or a deletion to the property can cause a change.
After you report these to the county assessor, you can expect to receive a notice of the new valuation of your property on or before September 30.
You have 25 days to appeal the valuation to the State or County Board of Equalization after you receive the notice. You can expect a ruling on your appeal by the third Friday of November. You may file a further appeal to the Tax Court within 60 days of the date the decision went into the mail.
