Arizona Property Taxes Due November 2026: Homeowner Guide
Quick answer
When are Arizona property taxes due in 2026 in Maricopa and Pinal County? First-half 2026 Arizona property taxes become delinquent after 5 p.m. on Monday, November 2, 2026, in both Maricopa and Pinal County. Maricopa County's bills went out late this year, but you can look up and pay yours online now. If your mortgage has an escrow account, your loan servicer normally pays the bill for you. Check that it did.
When are Arizona property taxes due in 2026?
Arizona splits property taxes into two halves. Under state law (A.R.S. 42-18052), the first half is due October 1 and becomes delinquent after 5 p.m. on November 1. The second half is due March 1 and becomes delinquent after 5 p.m. on May 1.
This year November 1 falls on a Sunday. State law says a weekend deadline moves to the next business day, so the real cutoff is Monday, November 2, 2026, at 5 p.m. The Maricopa County Treasurer's tax calendar lists that same date.
| Date | What happens |
|---|---|
| October 1, 2026 | First half of 2026 taxes due |
| November 2, 2026, 5 p.m. | First half delinquent after this time |
| December 31, 2026 | Pay the full year by now and no interest is charged on the first half |
| March 1, 2027 | Second half due |
| May 1, 2027, 5 p.m. | Second half delinquent after this time (May 1, 2027 is a Saturday, so check your county's posted date) |
Why were Maricopa County tax bills late this year?
The Maricopa County Treasurer's Office said some 2026 bills would arrive after the October 1 due date. The reasons were late changes to tax levies and rates, plus problems rolling out a new computer system, according to an azfamily report on September 30, 2026. The office apologized for the confusion.
You don't have to wait for the paper bill. You can look up and pay it at treasurer.maricopa.gov.
What happens if I pay late?
Arizona charges interest on delinquent property taxes at 16% per year, simple, under A.R.S. 42-18053. The Pinal County Treasurer notes that this interest can't be waived. If you pay the entire year's tax by December 31, the law says no interest is charged on the first half.
I have a mortgage. Do I need to do anything?
Look at your mortgage statement. If it shows an escrow account for taxes, your loan servicer collects part of the tax bill in each monthly payment and pays the county for you.
- Log in to your county treasurer's site and confirm the first half shows as paid.
- If it isn't paid by late October, call your servicer. Don't pay it twice without checking.
- Your servicer reviews your escrow once a year. If your tax bill went up, your monthly payment can go up too, even though your loan didn't change.

What if I don't have an escrow account?
Then the bill is yours to pay. Many homeowners with conventional loans waive escrow, and homes owned free and clear have no servicer at all. Set a reminder for November 2 and May 1, or pay the full year by December 31.
I'm buying a home in October or November. How do taxes work at closing?
Your title and escrow company handles it. They check the county record for unpaid taxes and split the year's taxes between buyer and seller based on the closing date. If the first half hasn't been paid, it's usually paid out of the closing funds so the home transfers with taxes current.
If you're getting a loan with an escrow account, the lender also collects a few months of property taxes up front to start that account. Those are prepaid costs, not fees, and they show up on your Loan Estimate and Closing Disclosure. I'll walk you through them before you sign anything.
