Five steps

How to protest your property taxes in Phoenix

1

Check whether your assessed value is too high

Compare your appraised value to what similar homes nearby actually sold for recently. If your number sits above those comparable sales, you likely have a case — and that, not the tax rate, is the part you can actually fight.

2

Know your Arizona deadline and process

Arizona's county Assessor mails a Notice of Value early in the year. You appeal to the Assessor first (generally within 60 days of the notice), and if needed escalate to the State Board of Equalization or Tax Court. Mark the date — miss it and you wait a year.

3

Gather your evidence

The strongest evidence is recent comparable sales of similar nearby homes priced below your assessment, plus anything that lowers your home's value — needed repairs, condition issues, photos. Bring specifics, not opinions.

4

Make your case

Start with the informal review — many protests are resolved right there. If not, present your comps and condition evidence at the formal hearing. Stay factual and organized.

5

Re-file next year if needed

Assessments reset every year, so protesting is something you can do annually. A win this year doesn't lock in next year's value.
