Are Phoenix property taxes leaving you with more questions than answers? Whether you are relocating to the Valley or planning a move across town, understanding how your home is valued and billed can help you plan with confidence. In this guide, you will learn how assessments work, how rates are applied, which exemptions may reduce your bill, and what timelines matter most. You will also get simple steps to estimate your taxes and avoid surprises. Let’s dive in.
How Phoenix property taxes work
In Maricopa County, the county assessor estimates your home’s value and sends you a Notice of Value each year. Arizona uses two values in this process. The assessor’s estimate of market value is called the full cash value. The taxable amount is the limited or assessed value, which is what your bill is based on.
Your annual tax is the taxable assessed value multiplied by the total tax rate from all overlapping jurisdictions that serve your property. These can include the city, county, school districts, fire districts, community colleges, and special districts. Because every parcel sits in a unique mix of districts, no single “Phoenix rate” applies to all homes.
What gets taxed: value and reassessments
After you buy a home, a change in ownership often triggers a revaluation for the next assessment cycle. Major improvements or new construction can also lead to a higher assessed value. If you stay in your home, Arizona provides protections that can limit how quickly the limited value increases from year to year.
Your Notice of Value shows both the full cash value and the limited or assessed value that the county plans to use for your taxes. If the numbers do not reflect your home’s condition or the market, you can review recent sales and consider an appeal within the stated deadline on the notice.
How rates are applied
Your bill reflects the sum of tax rates set by all jurisdictions that serve your parcel. School bonds and voter-approved overrides can make up a meaningful share of the total. You can confirm the current rate mix and view your bill with the Maricopa County Treasurer.
- Simple formula: Annual tax = Taxable Assessed Value × Total Tax Rate.
- Example: If your taxable value is $300,000 and your total rate is 1.2 percent, your estimated annual tax is $300,000 × 0.012 = $3,600. This is an example only. Use your parcel’s actual rate and taxable value for a real estimate.
To view your valuation details, use the Maricopa County Assessor. To see the tax rate breakdown and payment options, visit the Maricopa County Treasurer.
Exemptions and relief you can use
Arizona offers protections and relief that may lower the taxable value of your primary residence or help manage increases. In Maricopa County, common options include programs for seniors, people with disabilities, and qualifying low-income owners. There are also reductions for certain veterans with disabilities and special classifications for qualifying properties.
Most programs require an application with the county assessor and have documentation and deadline rules. For current eligibility details and forms, review the Maricopa County Assessor. For state-level guidance on property tax rules and exemptions, see the Arizona Department of Revenue’s Property Tax Division.
Billing, due dates, and penalties
Maricopa County follows an annual cycle. The Assessor typically issues Notices of Value in early parts of the year. Tax statements are usually mailed in the fall. Payments are often due in two installments, and the Treasurer publishes exact due dates and the penalty schedule each year.
If a payment is late, interest and penalties can accrue under county and state rules. Check the current tax calendar and payment options on the Maricopa County Treasurer to stay on schedule and avoid fees.
Buying or selling: what to expect at closing
Because tax bills arrive on a set schedule, closings in Phoenix usually prorate property taxes between the buyer and seller. The proration is commonly based on the most recent bill or an estimate if the current bill is not yet available. Your closing statement will show each party’s share for the period they own the property.
If you are financing the purchase, your lender may set up an escrow account to collect monthly portions of your taxes and insurance. Confirm escrow setup, initial deposits, and how the lender will coordinate with the county on your behalf.
Planning moves and remodels: avoid surprises
A sale often resets your assessment for the next cycle. If you buy a home that has been owned for many years, your taxable value could change after purchase, which may lead to a higher bill in the future. Substantial improvements such as additions, pools, or major renovations typically increase assessed value.
Plan for these changes in your budget and discuss timing with your lender and advisors. If you believe your post-purchase assessed value is out of line with the market, follow the appeal process promptly.
How to appeal your value
If you disagree with your Notice of Value, you can file a valuation protest with the county assessor within the deadline listed on your notice. Many counties use a 60-day window from the date on the notice, but always verify the exact deadline for Maricopa.
Prepare strong evidence, such as recent comparable sales, photos that show your home’s condition, inspection reports, and a professional appraisal if available. Some cases resolve through an informal conference with assessor staff. If not, matters can proceed to the county Board of Equalization and, if needed, to state-level boards or courts. Start by reviewing the process and forms on the Maricopa County Assessor.
