Rate Breakdown

Property taxes in Pinal County are calculated by multiplying the assessed value (minus exemptions) by the total local millage rate.

How Property Tax Works in Pinal County

In Pinal County, property taxes are calculated by multiplying the assessed value of a parcel by the combined millage rate set by the various taxing entities that serve the property (e.g., county, municipalities, school districts, fire districts). The process begins with the County Assessor’s Office, which determines the market value of a property each January 1. This market value is then adjusted by the appropriate assessment ratio—typically 100% for real property.

Once the assessed value is established, the County Treasurer’s Office applies the current millage rates. One mill represents $1 of tax per $1,000 of assessed value. For example, if the combined millage rate for a property is 38 mills, a home assessed at $250,000 would owe:

Tax = (Assessed Value ÷ 1,000) × Millage Rate
Tax = ($250,000 ÷ 1,000) × 38 = $250 × 38 = $9,500.

Millage rates can change each fiscal year, and they differ based on the location of the property within the county. The Treasurer’s website publishes a detailed table of all applicable rates, making it easy to verify the exact amount you’ll owe.

Available Exemptions

Pinal County follows Arizona state law regarding property‑tax exemptions. Eligible owners can reduce their taxable assessed value, which directly lowers the tax bill.

• Homestead Exemption: Reduces the assessed value of a primary residence by up to $150,000. Applicants must certify ownership and occupancy.
• Senior Citizen Exemption: Residents aged 65 or older may receive a $15,000 exemption on the assessed value of their primary dwelling.
• Disability Exemption: Qualified individuals with a permanent physical or mental impairment can claim a $15,000 exemption on their home’s assessed value.
• Veteran Exemption: Veterans who were disabled in the line of duty, or surviving spouses of disabled veterans, may qualify for a $15,000 exemption. Active‑duty military are not eligible for this exemption while on active service.

All exemptions require a completed application filed with the Pinal County Assessor’s Office, typically by April 15 of the tax year. Supporting documentation (proof of age, disability rating, military discharge papers, etc.) must be attached for verification.

Payment Schedule & Deadlines

Arizona property taxes are due in two installments. The first installment is payable on the first business day of October, and the second installment is due on the first business day of March of the following year. The Treasurer’s Office will mail billing statements about two weeks prior to each due date.

• Early payment discount: Some municipalities within Pinal County offer a 5% discount if the full amount is paid before the due date.
• Installment options: Taxpayers may split each installment into two equal payments (due on the 1st and 15th of the month) by enrolling in the “Partial Payment Plan” through the online portal.
• Late payments: A penalty of 10% of the unpaid amount is assessed after the due date, plus interest accruing at the statutory rate of 0.5% per month.

Failure to pay both installments can result in a tax lien, and eventually, a tax foreclosure. The County Treasurer provides online payment, mail‑in, and in‑person options at the Treasurer’s Office in Florence.

Appealing Your Assessment

If you believe your property’s assessed value is incorrect, you have the right to appeal. The appeal process consists of three steps:

1. Informal Review: Contact the Assessor’s Office within 30 days of receiving your notice of value. Provide comparative sales data, recent appraisals, or other evidence supporting a lower value.
> Formal Appeal: If the informal review does not resolve the issue, file a formal appeal with the Pinal County Board of Equalization (BOE) within 30 days of the denial. The appeal form is available online and must include a filing fee. > Hearing & Decision: The BOE will schedule a hearing where you may present testimony and documents. After the hearing, the Board issues a written decision, typically within 60 days. If unsatisfied, you may pursue further review in the Arizona Tax Court.

Throughout the process, keep copies of all correspondence, photographs, and any independent appraisals. Timely action and thorough documentation are key to a successful appeal.
