Tucson Property Tax: Find the Bill, Pay Pima County & Understand the Value Before It Gets Late
Tucson property tax is handled through Pima County, not a separate City of Tucson payment counter. Use the Treasurer for bills, payments, receipts, tax liens and due dates; use the Assessor for parcel value, classification, mailing address changes, exemptions and appeals. This page turns the official rules into quick steps so you can search, pay, calculate, fix errors and avoid interest.
What Tucson property owners usually need first
Pick your situation first. The right office depends on whether the issue is payment, value, mailing address, appeal, escrow or a lien.

How to look up Tucson property tax records
Use two official tools together: Treasurer for tax bills and balances, Assessor for parcel value and property facts.
| Need | Use This Office / Tool | Best Search Detail |
|---|---|---|
| Tax bill, balance or receipt | Pima County Treasurer | State code / parcel number, tax year, owner, address. |
| Value, classification or property details | Pima County Assessor | Parcel, address or owner name. |
| Map or parcel code | Pima parcel / GIS search | 8-digit numeric plus final alpha/numeric parcel code or formatted 11-character value. |
| Deeds or recorded documents | Pima County Recorder | Grantor, grantee, recording date, document number or legal description. |
| Mailing address change | Pima County Assessor | State code / parcel number, owner contact info, notarized form if needed. |
1
Start with the Treasurer for taxes due
This is where payment status and tax statements live.
▾
Open the Pima County Treasurer Property Inquiry. Search the property, open the parcel/tax year, then review due dates, installment status, payment history and any interest.
2
Use the Assessor when the number looks wrong
Value and classification problems are not payment problems.
▾
Open the Pima County Assessor and search by parcel, address or owner. Compare Full Cash Value, Limited Property Value, classification, property characteristics and mailing address.
3
If the address search fails, simplify
Portal formatting can be strict.
▾
Try house number plus main street name only. Remove apartment/unit, punctuation, directional words and road suffixes. Parcel/state code is usually better than address when available.
How to pay Tucson / Pima County property tax online or offline
Pima County Treasurer handles payment. Read the fee and deadline rules before clicking submit.
Online
eCheck fee listed by the Treasurer is $0.50 per transaction. Other online methods list 1.95% with a $1.95 minimum. Confirm the live fee screen before paying.
Mail payments by check, cashier’s check or money order. Treasurer says not to mail cash and payments must be in U.S. funds.
In person / wire
Cash payments should be made in person. For bank wire, contact the Treasurer at (520) 724-8341 before sending funds.
1
Open the official payment route
The Treasurer may redirect to an outside processor.
▾
Start from Pima County Treasurer payment information or the Treasurer property inquiry page. If redirected to a processor, confirm that the parcel, tax year, installment and amount match before entering payment information.
2
Choose the right installment
First half, second half and full-year payment behave differently.
▾
Most property taxes are payable in two installments. If you pay both installments by December 31, Pima County says interest that may have accrued after November 1 is waived. Always verify the live tax year and deadline shown on the bill.
3
Save proof and recheck posting
Useful for escrow, closing and lien disputes.
▾
Save the confirmation number, receipt, parcel/state code, amount, installment, payment date and payment method. Pima County says online payments are credited within 24 to 48 hours, so recheck the portal after processing.
Tucson property tax due dates and late-interest rules
The bill and Treasurer calendar control the live year. Use this table as the main Pima County rule pattern.
| Tax Item | Pima County Rule | Action |
|---|---|---|
| Tax statement mailed | Mailed in September to the address on the Assessment and Tax Roll. | Check the Treasurer portal if you do not receive it. |
| First half due | Due October 1. | Pay early; delinquent after November 1 at 5:00 PM. |
| Second half due | Due March 1. | Pay by May 1 at 5:00 PM to avoid delinquency. |
| Weekend / holiday | If delinquency date falls on weekend or legal holiday, delinquency time moves to 5:00 PM next business day. | Still pay before the deadline when possible. |
| Late interest | Unpaid balance after delinquency is subject to 16% per year / 1.333% monthly. | Ask Treasurer for exact payoff before paying late. |
How Tucson property tax is calculated
Pima County uses primary and secondary tax formulas. This matters because a Tucson bill can include City of Tucson, Pima County, schools, fire districts and voter-approved items.
Pima County calculation structure
Total tax = Primary Tax + Secondary Tax.
Primary taxes
Used for operating expenses of jurisdictions. Pima County applies primary rate to limited value through the assessment ratio formula.
Secondary taxes
Used for special districts, bonds, overrides and voter-approved items. These appear as separate lines on the tax bill.
State Aid to Education
Pima County describes this as a reduction for owner-occupied homeowners in the primary school district property tax.
| If Your Tax Seems High | Check This First | Correct Office |
|---|---|---|
| Value increased | Full cash value / limited value on Assessor record. | Pima County Assessor. |
| Classification wrong | Residential, commercial, vacant, mobile home or other class. | Pima County Assessor. |
| Rate changed | City, county, school, fire district and bond lines. | Jurisdiction listed on bill. |
| Payment penalty | Interest date, delinquent installment, prior-year balance. | Pima County Treasurer. |
How to challenge a Tucson property value or classification
The appeal belongs with the Assessor side, not the payment side. The Treasurer can collect, refund or apply corrections after the official correction process, but it usually cannot change value directly.
1
Review the Notice of Value
Pima County says the Assessor notifies owners of full cash and limited values by March 1.
▾
Check Full Cash Value, Limited Property Value, classification, property characteristics and mailing address. Save the Notice of Value because appeal timing is tied to it.
2
Appeal before the deadline
Do not wait for the tax bill if value is wrong.
▾
Use the Pima County Assessor appeals page. Arizona DOR also provides property valuation appeal forms. Prepare comparable sales, photos, property-record errors or classification evidence.
3
Pay while correction is pending if needed
Avoid interest while the issue is being reviewed.
▾
Pima Treasurer states it recommends paying the incorrect amount if a correction is pending because unpaid tax can accrue interest after the delinquency date. If the tax is lowered, overpayment may be refunded with applicable interest.
Exemptions, valuation relief and homeowner help
Arizona relief programs are handled through the Assessor. Eligibility, income rules, age/disability/veteran rules and deadlines can change, so use official forms and current instructions.
Exemption window
Arizona DOR says new exemption applications are submitted to the County Assessor during the annual application window from the first Monday in January to March 1.
Disabled / veteran relief
Arizona DOR points taxpayers to county assessors for exemption and valuation relief forms, including disability-related programs.
Senior freeze / valuation protection
Some qualifying homeowners may use valuation protection programs. Verify income, age and reapplication rules with the Assessor.
Having trouble paying
Pima Treasurer links to help resources. Contact the Treasurer before delinquency or tax lien problems become harder to fix.
How to change your Pima County property tax mailing address
This is handled by the Assessor, not the Treasurer. A wrong mailing address can cause missed Notices of Value and missed tax statements.
If you know the parcel/state code
Search your parcel on the Assessor website and change your address from the Contact Information area of the parcel detail page.
If you do not know the parcel
Use the Assessor change of mailing address request form. Pima Treasurer notes the form must be notarized.
After buying property
Check your mailing address, tax statement delivery and mortgage escrow responsibility. Title changes do not guarantee your mail is correct.
What to do if Tucson property tax is late or a tax lien is involved
Late property tax is high-risk because interest, tax liens and redemption rules can apply. Do not rely only on a screenshot if the tax is delinquent.
| Problem | Do This First | Why It Matters |
|---|---|---|
| First half missed | Ask Treasurer for current balance with interest. | Interest accrues after delinquency date. |
| Second half missed | Check May 1 delinquency and payoff amount. | Postmark/5 PM rules matter. |
| Tax lien sold | Contact Treasurer before paying online. | Delinquent tax liens may require full redemption. |
| Partial payment wanted | Check whether tax is current or delinquent. | Current partial payments may be allowed; delinquent lien partial payments may not be. |
| Escrow failed | Call mortgage servicer and Treasurer. | You need proof before interest or lien consequences grow. |
