Arizona property tax rates vary by county and what you own

Arizona has no statewide property tax rate. Instead, each county sets its own rate based on the value of your property and the local services that need funding — schools, fire departments, libraries, and county government. The effective rate (what you actually pay as a percentage of your home's value) ranges from roughly 0.6% to 1.2% across the state, depending on where you live and what exemptions you may have access to for.

Your property tax bill comes from two numbers multiplied together: the assessed value of your property and the tax rate for your county and district. The county assessor determines the assessed value, which is usually lower than the market value you paid. The rate is set by your county, city, school district, and any special districts that serve your property.

A home worth $400,000 in Maricopa County might pay roughly $4,000 to $5,000 per year, while the same home in Pinal County could be $3,500 to $4,500. The difference comes from both the county rate and the local school district's needs. These numbers shift annually as property values change and districts adjust their budgets.

Key Takeaways

  • Arizona property tax rates are set by county and vary from about 0.6% to 1.2% of assessed value, with no single statewide rate.
  • Your bill depends on the county assessor's valuation of your property and the combined rates of your county, city, school district, and any special districts serving your address.
  • Homeowners may reduce their tax bill through the primary residence exemption, which lowers the assessed value by a set amount that changes yearly.
  • Senior citizens, disabled persons, and surviving spouses of military members can claim additional exemptions that further reduce the assessed value.
  • Property tax bills are due in two installments: the first half by March 1 and the second half by October 1, with penalties for late payment.

How the assessed value is determined

The county assessor values your property every year, usually by looking at recent sales of similar homes in your area, the condition of your building, and the size of your lot. This assessed value is not the same as the market value — it is typically 10% to 20% lower. Arizona law requires the assessed value to be no more than 10% above or below the limited property value, which is based on prior-year values adjusted for inflation.

You can challenge the assessor's valuation if you believe it is too high. The process starts with a written request to the county assessor's office, usually due by a specific date in the spring. If you disagree with their response, you can appeal to the county Board of Supervisors or the Department of Revenue. Many counties offer informal review meetings where you can present evidence — recent appraisals, comparable sales, or photos of damage — without hiring a lawyer.

The assessor's office in your county publishes property values online, so you can look up your own assessed value and compare it to similar homes nearby. If your home was recently damaged or you made major renovations, the assessed value may not yet reflect that change, and you can request an adjustment.

Primary residence exemption and other deductions

Arizona's primary residence exemption reduces the assessed value of your home if you own it and live in it as your main home. The exemption amount changes each year — in recent years it has been around $3,000 to $3,500 — and is subtracted from your assessed value before the tax rate is applied. This directly lowers your tax bill.

To claim the exemption, you file a form with the county assessor, usually by a important date in the spring. You will need to prove you own the property and that it is your primary residence. Once approved, the exemption continues year to year unless you move or sell the home.

If you are 65 or older, disabled, or the surviving spouse of a military member who died in service, you may claim an additional exemption on top of the primary residence exemption. The amount varies by county and your income level. Some counties offer a full exemption for seniors with limited income, meaning you pay little to no property tax. You must reapply each year and provide proof of age, disability status, or military connection.

Tax rates by county and what affects them

Maricopa County (Phoenix area) has an effective rate around 0.65% to 0.75% of assessed value. Pinal County (south of Phoenix) runs slightly lower at 0.6% to 0.7%. Coconino County (Flagstaff area) is typically 0.8% to 1.0%. Yavapai County (Prescott area) ranges from 0.75% to 0.95%. These are rough ranges because the exact rate depends on which school district and special districts your property falls within.

The rate is built from layers: the county rate, the city rate (if you live in an incorporated city), the school district rate, and any special district rates (for fire, water, or library services). A property in Phoenix pays the Maricopa County rate plus the City of Phoenix rate plus the Phoenix Union High School District rate plus any special districts. A property outside city limits pays only the county, school district, and special district rates.

School districts make up the largest share of most property tax bills — often 40% to 60% of the total. When a school district's budget grows or a bond passes, the rate rises. When property values in the county increase, the rate may stay the same or drop slightly because the same revenue is spread across a larger tax base.

When your property tax bill is due and what happens if you miss it

Arizona property taxes are billed twice a year. The first installment is due by March 1, and the second is due by October 1. You will receive a bill in the mail from the county treasurer's office, usually a few weeks before each due date. If you have a mortgage, your lender may collect property taxes as part of your escrow account and pay the county directly.

If you pay late, the county charges a penalty. Missing the March 1 important date triggers a 10% penalty on the first installment. Missing the October 1 important date triggers a 10% penalty on the second installment. If you are more than 10 days late, the penalty increases. After three years of unpaid taxes, the county can place a lien on your property and eventually foreclose and sell it to recover the debt.

If you cannot pay your full bill, contact the county treasurer's office about a payment plan. Some counties offer installment agreements that let you spread the payment over several months without the full penalty. You can also request a deferral if you are a senior, disabled, or a surviving spouse of a military member — this postpones payment until you sell the home or pass away, though interest accrues.

How to find your specific tax rate and bill

Your county assessor's website lists the assessed value of your property and the tax rate for your address. Search for "[Your County] Arizona assessor" and look for a property search tool. Enter your address or parcel number, and you will see the assessed value, exemptions applied, and the combined tax rate.

The county treasurer's website also publishes tax bills online. You can search by address or parcel number to see your current bill, payment history, and due dates. Some counties let you set up automatic payments or pay online through their website.

If you want to understand the breakdown of your bill — how much goes to the school district, how much to the city, how much to special districts — the assessor's office can provide a detailed rate sheet for your property. This shows each layer of the rate and helps you see which entity is responsible for each portion of your tax bill.

Frequently Asked Questions

Can I pay my Arizona property taxes online?

Yes. Most Arizona county treasurer offices accept online payments through their websites. You can pay by credit card, debit card, or bank transfer. Some counties charge a small fee for credit card payments. You can also mail a check or pay in person at the treasurer's office.

What happens if I own property in more than one Arizona county?

Each county assesses and bills your property separately. You will receive a bill from each county treasurer for the properties in that county. Each bill follows the same March 1 and October 1 due dates. Exemptions must be claimed in each county where you own property.

Do Arizona property taxes go up every year?

The rate itself does not automatically increase, but your bill can rise if your assessed value increases or if your school district or special districts raise their rates. The county assessor adjusts values annually based on market conditions. If your home's value drops, your bill should drop too.

Are there property tax breaks for veterans in Arizona?

Surviving spouses of military members who died in service can claim an exemption that reduces assessed value. Active-duty military members and veterans do not receive a separate property tax exemption, but they may be may be able to access for other state benefits. Check with your county assessor about what programs you might may have access to for.

What is the difference between assessed value and market value?

Market value is what your home would sell for today. Assessed value is what the county assessor determines for tax purposes, usually 10% to 20% lower than market value. Arizona law caps how much the assessed value can rise year to year, even if the market value jumps. This protects long-term homeowners from sudden tax spikes.
