Arizona's property tax rate depends on your county and what the property is used for
Arizona does not have a single statewide property tax rate. Instead, each county sets its own rate based on local budget needs. The effective tax rate — what you actually pay as a percentage of your home's value — ranges from roughly 0.6% to 1.0% across the state, depending on which county you live in. A home worth $300,000 in one county might cost $1,800 to $3,000 per year in property tax, while the same home in another county could cost $2,400 to $3,600.
The rate also depends on what the property is used for. Residential property is taxed differently than commercial or agricultural land. Arizona also applies different rates to owner-occupied homes versus rental properties or vacant land. The county assessor determines the assessed value of your property, and the county tax collector applies the rate to that value.
Property taxes in Arizona are due in two installments: the first half is due by March 1, and the second half is due by September 1. If you have a mortgage, your lender may collect property tax as part of your monthly escrow payment and pay it on your behalf.

How county assessors determine your property's assessed value
The county assessor's office is responsible for estimating the market value of every property in the county. This estimated value is called the assessed value, and it is the number your tax rate is applied to. Assessors use recent sales of comparable properties, the condition and age of your home, square footage, lot size, and improvements like pools or additions to arrive at this figure.
You have the right to challenge the assessed value if you believe it is too high. The process is called a protest, and it must be filed with the county assessor by a specific deadline — usually in late May or early June, though this varies by county. You can file a protest yourself or hire a property tax consultant to do it. If the assessor does not lower the value after your protest, you can appeal to the county board of supervisors or pursue further legal action, though most disputes are resolved at the assessor level.
Assessed values are typically updated every year, though the increase is capped at 10% per year unless the property has been significantly improved or changed use. This means your tax bill can go up year to year, but not dramatically unless something major has changed about the property.
Homestead property tax reduction and other exemptions
Arizona offers a homestead property tax reduction for owner-occupied primary residences. If you own and live in your home as your main residence, you may reduce the assessed value by a fixed amount set by the state. The reduction amount changes each year — in recent years it has been around $3,000 to $4,000 — but you must file a claim with the county assessor to receive it. The reduction is not automatic, even if you have received it in previous years.
To claim the homestead reduction, you file Form 301 with the county assessor's office. You must own the property and occupy it as your primary residence on January 1 of the tax year. If you move or sell the property during the year, you may still be may have access to to the reduction for that year, but you will need to notify the assessor. The deadline to file is typically in late May or early June.
Arizona also offers property tax exemptions for certain properties, including churches, schools, hospitals, and government buildings. These properties pay no property tax at all. Disabled veterans and surviving spouses of veterans may also be may have access to to exemptions or reductions, though the rules are specific and require documentation from the Department of Veterans Services.
What happens if you do not pay property tax on time
If your property tax bill is not paid by the due date, the county adds a penalty and interest begins to accrue. The penalty is typically 10% of the unpaid amount, and interest accrues at a rate set by state law — currently around 10% per year, though this can change. The longer the bill remains unpaid, the larger the total amount owed becomes.
If property tax remains unpaid for three years, the county may place a tax lien on the property. This means the county has a legal claim against the property and can foreclose on it to recover the unpaid taxes. The foreclosure process in Arizona can take several months, but once it is complete, the county or a tax sale buyer becomes the owner and you lose the property.
If you are having trouble paying your property tax bill, contact the county tax collector's office immediately. Some counties offer payment plans or deferrals for taxpayers facing hardship, though these are not may provide and depend on your circumstances and the county's policies.
How to find your property tax rate and bill
Your property tax bill is mailed to you by the county tax collector, usually in late October or early November for the tax year that begins January 1. The bill shows the assessed value, the tax rate, and the amount due. If you do not receive a bill, contact the county tax collector's office — your address may be incorrect in their records, or the bill may have been lost in the mail.
You can also look up your property tax information online through the county assessor's website. Most Arizona counties maintain searchable databases where you can enter your address or parcel number and see the assessed value, tax rate, and recent tax history. The county assessor's website also lists the protest deadline and instructions for filing a protest if you want to challenge the assessed value.
To find your specific county's rate and assessor contact information, search for "[Your County] Arizona assessor" or "[Your County] Arizona tax collector." Each county's office maintains its own website with forms, deadlines, and contact numbers. If you are unsure which county you live in, you can search by address on the Arizona Department of Revenue website.
Differences between Arizona counties and what affects your rate
Arizona's 15 counties each set their own property tax rates based on local needs. Maricopa County (Phoenix area) and Pima County (Tucson area) are the largest and most populous, but their rates are not necessarily higher or lower than smaller counties. The rate depends on what local governments — the county, city, school district, and special districts like fire or water — need to fund their budgets.
A county with a newer school system or recent infrastructure projects may have a higher rate than a county with older, paid-off facilities. A county with a large commercial tax base may have a lower residential rate because the tax burden is spread across more properties. Rural counties sometimes have higher rates because fewer properties share the cost of county services.
Your actual property tax bill is the sum of taxes owed to multiple entities: the county, your city or town, your school district, and any special districts that serve your property. The county tax collector combines all of these into one bill, but each entity sets its own rate. This is why two homes with the same assessed value in the same county can have different tax bills if they are in different school districts or special districts.
Frequently Asked Questions
What is the average property tax rate in Arizona?
The effective property tax rate across Arizona ranges from about 0.6% to 1.0% of assessed property value, depending on the county and what entities tax the property. This is lower than the national average of around 0.8% to 1.2%, but it varies significantly by location within the state.
Can I deduct Arizona property taxes on my federal income tax return?
Yes, you can deduct state and local property taxes on your federal return, but only up to $10,000 per year total for all state and local taxes combined (including income tax and sales tax). This limit has been in place since 2017. Consult a tax professional about your specific situation.
Do I have to pay property tax if I own the land outright with no mortgage?
Yes. Property tax is owed on all real property in Arizona, regardless of whether there is a mortgage. The county does not care who owns the property or whether it is paid off — the tax is based on ownership and assessed value only.
What if I disagree with the assessed value the assessor gave my property?
You can file a protest with the county assessor by the deadline, usually in late May or early June. Bring evidence of the property's actual value, such as recent comparable sales or a professional appraisal. If the assessor does not reduce the value, you can appeal to the county board of supervisors.
Does Arizona have a property tax cap or limit on increases?
Arizona caps the annual increase in assessed value at 10% per year, unless the property has been significantly improved or changed use. This means your tax bill cannot jump dramatically from year to year, but it can still increase by up to 10% if the assessed value rises.
