Maricopa Property Tax Calendar for Scottsdale Homeowners

December 4, 2025

Property tax deadlines can sneak up on you, especially if you are juggling a move, a remodel, or a seasonal schedule. As a Scottsdale homeowner, you want a clear picture of what happens when so you can review your value, budget for payments, and avoid penalties. In this guide, you will get a month-by-month calendar, plain-English definitions, and simple action steps to stay ahead. Let’s dive in.

How Maricopa property taxes work

In Maricopa County, a few different offices play key roles:

  • The Assessor estimates your property’s value and sends the annual valuation notice. The Assessor also handles classifications, exemptions, and informal reviews.
  • The Treasurer sends the tax bill, collects payments, and posts delinquencies and penalties.
  • Local taxing jurisdictions such as the City of Scottsdale, school districts, and special districts set budgets and tax rates. The Treasurer combines these rates into one bill.
  • State laws set the rules for timing, appeals, valuation limits, and exemptions.

At a high level, your property tax is based on taxable value and the combined tax rates of all jurisdictions that serve your parcel.

Key terms you will see

  • Full cash value or market value: An estimate of what your home is worth in the market.
  • Valuation notice and assessed value: The value the county uses to calculate your taxes after applying state formulas and limits.
  • Tax levy or tax rate: The combined rate set by your city, school district, and special districts that is applied to your taxable value.
  • Exemption or classification: Programs and status that may reduce your taxable value or taxes, such as primary residence classification or veteran exemptions.
  • Delinquency and penalties: Charges and interest that apply if your bill is not paid on time.

Your Scottsdale property tax calendar

Important: Exact dates can change each year. Verify current-year deadlines on the official Maricopa County Assessor and Treasurer sites before you act.

January: Watch for your valuation notice

  • The Assessor typically mails valuation notices early in the year.
  • Review property details and your assessed value right away. Check bedrooms, square footage, lot size, and any changes listed.
  • Keep documentation that supports your view of value, such as recent comparable sales, an appraisal, or photos of condition issues.

After the notice: Appeal windows open

  • Your valuation notice will explain how to request an informal review and how to file a formal protest.
  • Deadlines are set by statute and are firm. The notice will state the exact last day to file.
  • If you disagree with the value, start with an informal review for a quicker resolution. If needed, submit a formal protest by the deadline with supporting evidence.

March to June: Appeal processing

  • The Assessor reviews protests and may hold hearings or issue decisions during spring.
  • Track your case status and read the decision letter carefully. It will outline any further appeal rights and timelines if you wish to continue.

Late summer to early fall: Watch for your tax bill

  • After local budgets and levies are set, the Treasurer prepares and mails annual tax bills, commonly in early fall.
  • Compare your bill with the Assessor’s valuation and check that any exemptions or classifications you claimed are showing correctly.

October to November: Primary payment due

  • Maricopa County historically uses a fall due date. Your bill will list the exact due date and any installment options.
  • Pay by the date shown to avoid penalties. If you escrow with a mortgage servicer, confirm the servicer received the bill and made payment from your escrow account.

After the due date: Penalties and delinquency

  • Unpaid taxes begin to accrue penalties and interest according to the Treasurer’s schedule.
  • If you cannot pay in full, contact the Treasurer right away to ask about payment options and current penalty rules. If your taxes are escrowed, involve your servicer immediately.

Next spring to summer: Collection steps

  • Continued nonpayment can trigger additional penalties, interest, and potential tax lien actions allowed under state law.
  • Address issues early. If you are disputing a bill, use the protest process within deadlines and keep records of communications.

Appeals and exemptions

How to protest your valuation

  • Start with an informal review through the Assessor. It is often the fastest way to resolve issues.
  • If you still disagree, file a formal protest by the deadline printed on your valuation notice. The notice explains how to file online, by mail, or in person.
  • Use strong evidence. Include comparable sales, an independent appraisal if available, and photos or reports that show physical conditions that affect value.

Exemptions and classifications to check

  • Primary residence classification: Confirm your home is recorded as your primary residence if applicable. This status can affect how your value is treated.
  • Age, disability, and veteran-related benefits: Arizona and Maricopa County offer programs that can reduce taxable value or adjust valuation rules for eligible homeowners, including certain disabled veteran exemptions.
  • Application timing: Exemptions are not always automatic when you buy a home. Verify your status and file the required forms before the stated deadline.

Ownership changes and new construction

  • After a sale or transfer: A change in ownership can affect future valuations. Confirm your deed is recorded correctly and that the Assessor and Treasurer have your current mailing address.
  • New construction or improvements: Significant improvements may lead to higher valuations in the next cycle. Keep an eye on permits and the Assessor’s records so there are no surprises.

Buyers and sellers at closing

  • Proration: Property taxes are typically prorated at closing. The seller pays the portion up to closing, and the buyer takes the remainder for the year.
  • Escrow: If you are a buyer using an escrow account, confirm taxes are included in your monthly escrow budget and that your lender will pay the bill when due.

Paying your bill

  • Payment methods: The Treasurer usually accepts online payments, checks or money orders, and in-person payments. Electronic payments may involve third-party processors and fees.
  • Cutoff times and fees: Online payment cutoffs and convenience fees can vary. Always check the Treasurer’s current payment instructions well before the due date.
  • If you escrow: Even when your servicer pays taxes on your behalf, review the bill, confirm payment, and keep proof in your records.

If you fall behind

  • Do not wait. Contact the Treasurer immediately to ask about partial payments, payment options, and how penalties and interest are calculated.
  • If your mortgage servicer is responsible for paying, notify them in writing and request confirmation of payment.
  • Keep a file with dates, names, and copies of all communications until the issue is resolved.

Scottsdale specifics to keep in mind

  • Scottsdale parcels can fall into different school, fire, and special districts. That mix affects the tax rate you see on your bill.
  • Review the line items on your final bill to understand how city, school, and special district levies add up.
  • Use the county’s parcel lookup tools to confirm which jurisdictions apply to your property and to see how your value and taxes have changed over time.
