Rate Breakdown

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

How Property Tax Works in Cochise County

In Cochise County, property tax is based on the assessed value of real and personal property located within the county’s borders. Each year the County Assessor’s Office conducts a market‑value assessment, which reflects what the property would likely sell for on the open market as of the assessment date (usually January 1). After the market value is determined, the assessor applies a uniform “assessment ratio” of 10 % for residential property, 30 % for commercial/industrial, and varying ratios for agricultural land, personal property, and other classifications. The resulting figure is the “assessed value” on which tax calculations are made.

Once the assessed value is set, the County Treasurer multiplies it by the applicable millage rates (tax rates). A mill is one‑tenth of one percent, or $1 of tax per $1,000 of assessed value. Cochise County’s total millage rate consists of several components:

• County general fund (approx. 35 mills)
• School district rates (often the largest portion, ranging from 120‑150 mills)
• Fire, road, and other special districts (typically 10‑30 mills each)
• Any voter‑approved bonds or community‑specific levies

The combined rate is published each July and remains in effect for the fiscal year that runs from July 1 to June 30. Property owners receive a tax bill that shows the assessed value, the total millage, and the resulting amount due.

Available Exemptions

Arizona law provides several exemptions that can lower a homeowner’s taxable base. The most common exemptions in Cochise County are:

• Homestead Exemption: Reduces the taxable value of a primary residence by $150,000. Eligibility requires ownership and occupation as a principal residence on the assessment date.
• Senior Citizen Exemption: Residents age 65 or older may receive an additional $10,000 reduction in assessed value, plus a $2,000 property tax credit if they meet income limits.
• Disability Exemption: Qualified disabled persons can claim a $5,000 reduction; veterans with service‑connected disabilities may receive higher reductions based on the degree of disability.
• Veteran Exemptions: Full‑time veterans, disabled veterans, and surviving spouses can obtain either a homestead level exemption or a percentage reduction (up to 70 %) depending on rank, service duration, and disability rating.

All exemptions must be applied for through the Cochise County Assessor’s Office, typically by March 31 of the tax year. Supporting documentation—such as proof of age, disability rating, or veteran status—is required.

Payment Schedule & Deadlines

Property taxes in Cochise County are due in two installments:

• First installment: Due October 1; a 10 % discount is offered for payment made before this date.
• Second installment: Due March 1; a 5 % discount is available if paid before the deadline.

Payments can be made online via the County Treasurer’s portal, by mailed check, or in person at the Treasurer’s Office. If both installments are paid by the March 1 deadline, the full discount applies.

Late payments incur a 10 % penalty plus interest calculated at the statutory rate of 5 % per annum, compounded monthly. Continued delinquency may lead to tax lien filing, which can eventually result in a tax foreclosure.

Appealing Your Assessment

If you believe your property’s assessed value is inaccurate, Cochise County provides a clear appeal process:

• Step 1 – Review the Notice: The assessment notice, mailed each June, includes the assessed value and instructions for filing an appeal.
• Step 2 – File a Complaint: Submit a written appeal to the Cochise County Board of Equalization by the deadline (generally July 31). The filing must include your name, parcel number, the assessed value you are contesting, and supporting evidence (comparable sales, appraisals, or photographs).
• Step 3 – Attend a Hearing: The Board will schedule a hearing, usually within 30 days. You may present your case in person or by proxy.
• Step 4 – Decision: The Board issues a written decision within 15 days of the hearing. If you are unsatisfied, you may appeal further to the Arizona Tax Court.

Preparing a strong appeal package—relying on recent sales of similar properties, a professional appraisal, or documented errors—greatly enhances the likelihood of a favorable adjustment.
