Pima County property taxes: the Nov 1 half and the Dec 15 court date
By Trameze Jones, REALTOR® · Last updated Nov 2026
Pima County's assessor calendar, accessed Nov 2, 2026, says the first half of current-year taxes is due Nov 1. The second half is due March 1 and becomes delinquent May 1. Tax is calculated on Limited Property Value, not Full Cash Value. The 2026 notice mail date was Aug 28, 2026. The assessor appeal deadline was Sep 29, 2026.
Data as of Assessor calendar accessed Nov 2, 2026; 2026 notice dates from the assessor's Aug 21, 2026 post.
| Date | What it is | Status on Nov 2, 2026 |
|---|---|---|
| Aug 28, 2026 | 2026 Notices of Value mailed | Passed |
| Sep 29, 2026 | Assessor appeal deadline | Closed |
| Nov 1 | First half of current-year tax due | Due date on the calendar |
| Dec 15 | Tax Court filing if no assessor appeal | Still the stated deadline for the valuation year |
| March 1 | Second half due | Delinquent May 1 |
Pima County's assessor calendar, accessed Nov 2, 2026, says the first half of current-year taxes is due Nov 1. The second half is due March 1 and becomes delinquent May 1. The tax is calculated on Limited Property Value, not on Full Cash Value.
The 2026 Notices of Value were mailed Aug 28, 2026. The assessor's office said so on Aug 21, 2026, and set the appeal deadline at Sep 29, 2026. That window is closed. The assessor's generic calendar still says notices go out on or before March 1. That is the standing calendar, not the 2026 mail date. The 2026 dates are the Aug 28 mail date and the Sep 29 deadline.
What are the 2026 tax and appeal dates?
If you did not appeal through the assessor, the Arizona State Board of Equalization describes a direct filing in Tax Court until Dec 15 of the valuation year.
The relief programs on the assessor's valuation page are separate from that deadline. Senior Valuation Protection freezes Limited Property Value in three-year increments. It does not freeze the tax. There is also a widow or widower exemption, and a disabled veterans exemption tied to a VA combined disability rating.
What would Trameze do?
What Trameze would do is compare Full Cash Value with recent sales on the same street before deciding whether an appeal is worth the filing.
What are the short answers?
When are Pima County property taxes due?
The assessor's calendar says the first half of current-year taxes is due Nov 1. The second half is due March 1 and delinquent May 1.
Can I still appeal a 2026 value after the September deadline?
The 2026 Notices of Value were mailed Aug 28, 2026, with an assessor appeal deadline of Sep 29, 2026. That window is closed. If you did not appeal through the assessor, the Arizona State Board of Equalization describes filing in Tax Court until Dec 15 of the valuation year.
