Arizona Property Taxes Explained for Home Buyers (Peoria, Glendale and the West Valley)

"Arizona property tax calculator" is one of the most searched questions from buyers, and the confusing part is that the system works differently than in many states. Here is a plain-English walkthrough, and how to estimate the bill on a specific home in Peoria, Glendale, Surprise or anywhere in Maricopa County.

Two values, not one

Every Arizona property has a Full Cash Value (FCV), which is roughly the market value as set by the county assessor, and a Limited Property Value (LPV). The LPV is the number the tax bill is actually based on. For most Maricopa County homes, the LPV can rise by no more than 5% a year, even if market values jump, and it cannot exceed the FCV. The Maricopa County Assessor explains this on its page, Understanding Limited Property Value.

Significant changes, such as new construction, demolition or a change in use, can reset the LPV. That matters for new-build buyers, because a newly built home's value is established fresh.

From value to tax

1. The LPV is multiplied by the assessment ratio set in state law. For owner-occupied residential property, this has been 10% for decades; confirm the current ratio with the assessor.
2. That assessed value is multiplied by the combined tax rates of the districts the property sits in.

Those rates are a mix of primary taxes, which fund the operating budgets of the county, cities, schools and community colleges, and secondary taxes, which fund special districts and voter-approved bonds and overrides. Because the districts differ by address, two similar homes in the same city can have different tax rates.

How to estimate a specific home

• Look up the parcel on the Maricopa County Assessor and Treasurer websites. They show the current values and the prior tax bill.
• Do not assume the seller's bill is yours. A new buyer's bill follows the LPV rules, but a new home or major improvements can change it, and districts can change their rates.
• Ask your lender for the escrow estimate, because most buyers pay taxes monthly through an impound account.

Why the number can differ from an online calculator

Online calculators use averages. Your bill depends on the LPV, the district rates and any exemptions, so use them for a rough idea only and verify with the county.

A simple worked example

Here is a made-up illustration, not a prediction for any home. Suppose a home's Limited Property Value is $300,000. With a 10% assessment ratio, the assessed value is $30,000. If the combined tax rate for the districts at that address were 10 dollars per $100 of assessed value, the bill would be about $3,000 a year. Real rates and values differ, so look up the actual parcel. The point is the structure: value, then ratio, then the district rates.

Exemptions and special situations

• Senior, disability and veteran programs may reduce a bill for qualifying owners. Check with the county assessor for eligibility.
• Property tax appeals are available if you believe the valuation is wrong, and there are deadlines. The assessor's website explains the process.
• Rental use is taxed differently from owner-occupied use. If you plan to rent a home out, ask the county how it will be classified.
• New construction starts with a fresh valuation. For a home under construction, ask your lender how taxes are being estimated.

When and how you pay

Arizona property taxes are paid in two installments, and the dates are set by the county. If you have a mortgage with an escrow account, your lender typically pays the bills from your monthly payments. If you pay cash or have no escrow, you must pay them yourself. The county treasurer's site has the current due dates and payment options.

What this means when you are negotiating

At closing, property taxes are prorated between buyer and seller. Your title company handles the math. Ask your lender and the title company for the estimate. If you have questions about a particular tax bill, the county can answer them directly.

Frequently asked questions

How are property taxes calculated in Arizona?

The county assigns a Limited Property Value, multiplies it by the assessment ratio to get the assessed value, and then applies the combined tax rates of the districts where the property sits.

Is there a cap on how much Arizona property taxes can rise?

For most Maricopa County homes the Limited Property Value can rise by no more than 5% a year, but your actual tax bill also depends on district rates, which can change.

Are property taxes in Peoria or Glendale high?

Compare the real bills on specific homes. Rates vary by taxing district, so there is no single number for a whole city.

Where can I look up the taxes on a specific home?

The Maricopa County Assessor and Treasurer websites let you search by address or parcel.

What it means for your budget

Property tax is one line of the monthly cost of owning, along with insurance and any HOA fee. See my guide to building a realistic budget, and check my guide to HOA fees for the other recurring charge. If you want help estimating the monthly cost of a particular home, send it to me.
