Arizona Property Value Estimator

Arizona taxes the limited property value at a 10% assessment ratio — not the full cash value. Enter the values from your notice of valuation and estimate the property tax that follows.

This is an estimate, not an appraisal. The tool does not value your property; it works through Arizona’s value chain from a figure you supply. It is not an official assessment, tax bill, or professional valuation.

How the Arizona estimate is calculated

The estimator applies Arizona’s verified value chain to the value you enter: the figures that convert a market value into the taxable value the rates apply to, using the state’s own assessment ratio, exemption amounts and cap mechanics. The state does not supply rates — rates are local — so the optional tax estimate uses the rate from your own bill. Every rule number is cited below and was verified from the official source listed.

Limitations

• This is not an appraisal: the full cash value you enter is assumed, not estimated by the tool.
• The LPV formula (prior LPV + 5%, capped at FCV) cannot be simulated without the prior year's LPV; the tool uses the LPV from your notice instead, or the FCV if you leave it blank.
• The 10% ratio applies to class three and class four residential property; other classes use different ratios and are not modeled.
• Rates are set per $100 of assessed value by each jurisdiction in August; your combined figure may differ from the sum that actually applies.

Frequently asked questions

Why does Arizona tax a different value than my market value?

Since Tax Year 2015, Arizona has levied no tax on the full cash value. The tax base is the limited property value — the prior year's LPV plus 5%, never above the current FCV — and the rate is applied to 10% of that figure.

Why is my assessed value only 10% of my property's value?

Arizona's class three and class four residential assessment ratio is 10% of the limited property value. The small number is intentional; rates are correspondingly expressed per $100 of assessed value.

Why can my actual tax bill be different?

Without the LPV from your notice the tool uses the full cash value, which usually overstates the base. Rates also differ by jurisdiction, and the bill can include non-ad valorem items this estimator does not model.

Is this an appraisal?

No. The full cash value and limited property value come from your county assessor's notice of valuation, and appeals of the full cash value run through the assessor's petition for review.
