Arizona property tax rates vary by county and what you own, but the statewide average is around 0.62% of your home's assessed value
Arizona has no single property tax rate. Instead, each county sets its own rate based on the services it funds — schools, fire departments, libraries, and local government. Your actual bill depends on three things: your county, your home's assessed value, and whether you own residential property, commercial property, or agricultural land. A home worth $300,000 in Maricopa County will have a different tax bill than the same home in Pima County.
The statewide average effective tax rate — what people actually pay as a percentage of home value — hovers around 0.62%, but this varies significantly. Some counties run closer to 0.5%, while others reach 0.7% or higher. The county assessor's office determines your home's assessed value every year, and that number is what the tax rate is applied to, not the market price you paid.
Key Takeaways
- Arizona property tax rates are set by county, not statewide, so your rate depends on where your property is located.
- Your tax bill is calculated by multiplying your home's assessed value (determined by the county assessor) by your county's tax rate.
- The county assessor reassesses residential property values annually, and you can challenge the assessment if you believe it is too high.
- Homeowners over 65, disabled homeowners, and agricultural property owners may reduce their tax bill through exemptions or deferrals available through the county assessor.
- Property taxes in Arizona are typically due in two installments: one in October and one in March, with penalties for late payment.
How the county assessor determines your home's value
The county assessor's office physically inspects properties and reviews sales data to set an assessed value each year. They look at the condition of your home, its size, age, lot size, and recent sales of comparable homes in your area. This assessed value is not the same as what you paid for the house or what a real estate agent says it is worth today — it is the assessor's estimate of market value for tax purposes.
Arizona law requires the assessor to value property at 10% of its full cash value. This means if the assessor determines your home's full cash value is $300,000, your assessed value for tax purposes is $30,000. The tax rate is then applied to that $30,000 figure, not the $300,000. This 10% ratio is called the assessment ratio, and it is the same across all residential property in Arizona.
You receive a notice of assessed value in the mail, usually in July. If you disagree with the value, you can file a protest with the county assessor's office. The important date to protest is typically 30 days from the date on the notice, though you should check your county's specific important date. You do not need a lawyer or appraiser to protest — you can submit a letter explaining why you think the value is wrong, along with evidence like recent appraisals or comparable sales.
What your county's tax rate actually includes
When you see a county tax rate listed, it is actually a combination of several smaller rates stacked together. Your county government sets a base rate for general operations. On top of that sit rates for schools, community colleges, fire districts, water districts, and sometimes special improvement districts. Each of these entities sets its own rate, and they all add up to your total county rate.
For example, Maricopa County's combined rate for 2024 is approximately 0.62%, but that includes funding for Maricopa County government, the Maricopa County Community College District, various school districts, and fire districts. Pima County's rate is different because it has a different mix of districts and different funding needs. If you live in a town within a county, you may also pay a town tax rate on top of the county rate, though some Arizona towns do not levy property taxes.
You can find your specific county's rate breakdown on the county assessor's website or by calling the assessor's office. They can tell you exactly which districts are included in your bill and what portion of your payment goes to each one.
Calculating your actual property tax bill
The formula is straightforward: assessed value × tax rate = annual property tax. If your home's assessed value is $30,000 and your county's combined tax rate is 0.0062 (which is 0.62% written as a decimal), your annual tax is $186. This is then divided into two payments, typically due in October and March.
Your county assessor's office sends you a property tax bill in the mail. The bill shows your assessed value, the tax rate, the total amount due, and the two payment dates. You can pay online, by mail, or in person at the assessor's office or county treasurer's office. If you pay late, penalties and interest accrue — the exact amount varies by county but typically starts at 10% of the unpaid amount.
Some counties allow you to pay the full year's tax in one lump sum rather than two installments, though this is not required. Check your county treasurer's website for payment options and important date specific to your location.
Exemptions and deferrals that reduce your tax bill
Arizona offers several ways to lower your property tax bill if you meet certain conditions. Homeowners age 65 or older can claim a homeowner's exemption that reduces the assessed value of their primary residence. The exemption amount varies by county but typically reduces your assessed value by $2,500 to $4,000, which directly lowers your tax bill.
Disabled homeowners and disabled veterans may also reduce their tax bill through exemptions or deferrals. A disabled person can defer their property taxes until the property is sold or transferred, meaning you do not pay taxes now but the state places a lien on the property to collect the deferred amount later. Disabled veterans may receive an exemption similar to the senior exemption.
Agricultural property is taxed differently than residential property. If you own land used for farming or ranching, you may be able to claim an agricultural exemption that values the land based on its use for agriculture rather than its potential development value. This can result in a much lower assessed value and tax bill. To claim any of these exemptions, you must file a claim with your county assessor's office — they do not happen automatically.
How Arizona property taxes compare to other states
Arizona's effective property tax rate of around 0.62% is below the national average of approximately 0.84%. This means Arizona homeowners generally pay less in property tax as a percentage of home value than residents of many other states. However, this does not account for other taxes — Arizona has a state income tax, and some states have no income tax but higher property taxes.
The total tax burden depends on your income, home value, and which state you live in. A high-income earner in Arizona may pay more total tax than a lower-income earner in a state with no income tax but higher property taxes. Property tax alone is not the full picture of tax burden, but for homeowners focused specifically on property taxes, Arizona is relatively moderate.
Frequently Asked Questions
Can I appeal my assessed value if I think it is too high?
Yes. You have 30 days from the date on your notice of assessed value to file a protest with the county assessor. You can submit a letter explaining your disagreement and include evidence like recent appraisals, comparable sales in your neighborhood, or photos showing property condition. The assessor will review your protest and either adjust the value or uphold it. If you disagree with the assessor's decision, you can appeal to the county board of supervisors.
What happens if I do not pay my property tax bill on time?
Late payments incur penalties and interest. The exact amount varies by county but typically starts at 10% of the unpaid amount. If you continue not to pay, the county may eventually foreclose on your home and sell it to recover the unpaid taxes. If you are struggling to pay, contact your county treasurer's office — some counties offer payment plans or can direct you to information programs.
Do I have to pay property tax if I own my home outright with no mortgage?
Yes. Property tax is owed by the property owner regardless of whether the home is paid off or financed. If you have a mortgage, your lender typically requires you to pay property tax as part of your monthly escrow payment. If you own the home outright, you are responsible for paying the tax bill directly to the county.
Are there property tax breaks for first-time homebuyers in Arizona?
Arizona does not offer a statewide property tax exemption or reduction for first-time homebuyers. However, some individual towns or special districts may offer local incentives. Check with your city or town government and your county assessor's office to see if any local programs explore to your situation.
How often does the county reassess my home's value?
The county assessor reassesses residential property annually. You receive a new notice of assessed value each year, usually in July. The value can go up or down depending on changes to your property and market conditions in your area. Commercial and industrial property may be reassessed on different schedules — check with your county assessor for specifics.
