Who sends the property tax bill in Pima County, and how do you pay it?
The bill comes from the Pima County Treasurer's Office. The value it is based on is set by a separate office, the Pima County Assessor's Office, which is who to ask if the value looks wrong. For how to look up and pay the bill, go to the county's own payment information.
Tax statements are mailed each September with coupons for both halves. The Assessor's notice of value, mailed by March 1, sets the value for the following tax year: the notice mailed in early 2026 sets the value for the 2027 bill, not this one. Online payments go through the county's third-party payment portal: e-checks cost $0.50 and other methods 1.95% with a $1.95 minimum, and cards used in person at the Treasurer's office carry a 2% fee. Phone payments are not accepted. Partial payments on current taxes are allowed, at least $10 or 10% of the tax due, whichever is greater.
When are property taxes due in Pima County?
For the 2026 bill, Pima County splits the bill into 2 payments, the first due November 2, 2026 and the last May 3, 2027. Any unpaid balance after the delinquency date is charged simple interest at the state rate of 16% a year (1.333% a month), and part of a month counts as a whole month. Mailed payments postmarked after the delinquency date are late.
| Payment | Due | Note |
|---|---|---|
| First half (last day to pay without interest) | November 2, 2026 | The first half is legally due October 1, 2026, but no interest is charged until it becomes delinquent after 5 p.m. on November 1. November 1, 2026 is a Sunday, and state law moves a delinquency date that falls on a weekend or legal holiday to 5 p.m. the next business day, so the Treasurer's calendar sets the deadline at Monday, November 2, 2026 (mailed payments must be postmarked by then). If the whole year's tax is $100 or less, it is all due October 1 and does not become delinquent until after 5 p.m. on December 31, 2026. Paying the full year by December 31, 2026 waives any interest that built up on a late first half, although that first half is still legally delinquent. |
| Second half (last day to pay without interest) | May 3, 2027 | The second half is legally due March 1, 2027, but no interest is charged until it becomes delinquent after 5 p.m. on May 1. May 1, 2027 is a Saturday, so the treasurer's calendar sets the deadline at Monday, May 3, 2027 (mailed payments must be postmarked by then). |
