Whether you’re a first-time homebuyer in Tucson or a long-time resident of Oro Valley, understanding property taxes in Pima County is essential. These taxes fund vital community services such as schools, public safety, and road maintenance while also influencing your total cost of homeownership.
This guide breaks down everything you need to know about Pima County property taxes so you can stay informed and confident in managing your responsibilities as a homeowner.
What Exactly Are Property Taxes?
Property taxes are annual charges imposed by local government authorities including counties, cities, and special districts on real estate owners. The money collected helps fund essential public services like police and fire departments, public schools, infrastructure maintenance, and community improvements.
In Pima County, property taxes are distributed among multiple taxing bodies, including the county, municipalities, school districts, and fire districts. Each entity determines its own tax rate, which together make up your total property tax bill.
How Much Is Property Tax in Pima County?
In Pima County, the Assessor’s Office determines the value of your property, which serves as the foundation for your tax bill. Arizona uses two types of valuation for taxation purposes:
- Full Cash Value (FCV): The estimated market value of your property.
- Limited Property Value (LPV): The value used to calculate property taxes, which cannot increase by more than 5% annually under Arizona law.
The combined property tax rate in Pima County varies depending on your property’s location and which taxing jurisdictions apply. On average, homeowners pay an effective tax rate of approximately 0.8% to 0.85% of their home’s market value which is slightly below the national average.
When Are Property Taxes Due in Pima County?
Property taxes in Pima County are billed in two installments each year:
- First Half: Due on October 1 and delinquent after November 1
- Second Half: Due on March 1 and delinquent after May 1
Homeowners can also choose to pay the full annual amount by December 31. Staying current with these deadlines is vital to avoid interest and penalties.
When Will You Receive Your Property Tax Bill?
Property tax bills in Pima County are typically mailed by September each year.
If your bill does not arrive, you are still responsible for making payment by the due date. You can look up your parcel, view your bill, or make payments online through the Pima County Treasurer’s Office website.
What Happens If You Miss the Pima County Property Tax Due Date?
If you miss the payment deadline, penalties and interest accrues from the delinquency date. The Pima County Treasurer’s Office charges 16% annual interest (1.33% per month) on delinquent property taxes, as set by Arizona law.
Unpaid taxes can result in a tax lien sale, where your property’s tax debt is sold to investors. If left unresolved, this could ultimately lead to foreclosure. Staying on top of due dates ensures your property remains in good standing.

If you do not receive your bill, you can access your property information and perform a lookup through the Treasurer’s Office website or by calling (520) 724-8650.
Property Tax Reassessments in Pima County
Pima County reassesses properties annually to reflect changes in market value and ensure fairness in taxation.
Reassessments may result in an increase or decrease in your property’s Limited Property Value (LPV), depending on local market trends. Here’s what to know:
- If home values in your area rise, your assessed value and potentially your property tax bill may increase.
- Significant renovations or new construction can trigger a reassessment outside the regular annual cycle.
- When you purchase a home, taxes are prorated based on the previous year’s valuation, but your bill may increase once the Assessor updates the value to reflect your purchase price.
For questions about your assessed value or to appeal an assessment, contact the Pima County Assessor’s Office or visit their website.
