| Tax event | General date | Practical meaning |
|---|---|---|
| First half due | October 1 | First installment is due and payable. |

For a specific tax year, check the Treasurer’s current calendar and the tax statement rather than relying on a generic date table. This is especially important when a deadline falls near a weekend or holiday.
What happens when Maricopa County property taxes become delinquent?
Arizona law provides for 16% simple annual interest on delinquent property taxes, with a statutory exception when the full-year tax is paid on or before December 31 of the tax year. :contentReference[oaicite:20]{index=20}
Interest and account activity can change the amount due. Get the current figure from the Treasurer.
A prior-year delinquency is not the same as a current-year installment. Confirm which year and installment remain unpaid.
If the account has moved into a lien or enforcement stage, ordinary payment instructions may not answer every question.
Maricopa County tax lien sales and delinquent-tax research
Maricopa County’s Treasurer conducts tax-lien activities involving delinquent property taxes. County annual-report material describes an online auction of delinquent property-tax liens in February and a process for liens that are not sold at auction. :contentReference[oaicite:21]{index=21}
If your property has delinquent taxes, first establish the current account balance and enforcement status with the Treasurer. Do not assume that an ordinary online tax payment screen answers a tax-lien or redemption question.
Use the Treasurer’s dedicated tax-lien resources for auction information, certificates, research and related procedures. Tax-lien investing involves legal and financial risks outside the scope of this guide.
Maricopa County Treasurer vs Assessor
The distinction is simple but important: the Treasurer collects property taxes; the Assessor identifies property, maintains assessment information and establishes taxable values and exemptions. The Assessor’s own payment guidance directs tax-bill questions to the Treasurer. :contentReference[oaicite:22]{index=22}
| Your problem | Start with | Why |
|---|---|---|
| I need to pay my tax bill | Treasurer | The Treasurer handles property-tax collection. |
| My property value looks wrong | Assessor | Valuation is an assessment function. |
| I need an exemption question answered | Assessor | Assessment and exemption records are handled by the Assessor. |
| My payment has not posted | Treasurer | Payment posting belongs to the collection side. |
| I need to find my parcel/APN | Assessor | The Assessor provides parcel and property-search resources. |
What if your mortgage company pays the property tax?
Mortgage-serviced property taxes create a common duplicate-payment problem. A tax statement can exist even when a lender or tax-servicing company is responsible for paying it. Before sending your own payment, compare the Treasurer’s account with your escrow or mortgage payment records.
- Check the Treasurer account before making a second payment.
- Review your mortgage escrow history for the tax disbursement.
- Ask the mortgage servicer for the payment date and confirmation if its records show payment.
- If you recently purchased the property, review the closing statement for tax prorations.
- Do not assume a closing credit means the Treasurer already received the tax payment.
