What is FOR-144 V5?
The 2026 Exemption Deadline Waiver (printed as FOR-144 V5, Exemption Deadline Waiver) is the Maricopa County Assessor form that records a request to waive the filing deadline for a property tax exemption when the exemption application was filed on or after March 1.
The form states its purpose: an application for tax exemption filed on or after March 1 constitutes a waiver of the deadline under A.R.S. § 42-11153. By signing, the applicant asks that the waiver of the deadline be redeemed by the Maricopa County Board of Supervisors under that same statute.
You check one exemption type at the top: Personal (Widowed/Totally Disabled/Disabled Veteran) or Organizational. The form then asks for the date, the parcel or account number, the applicant's contact details and the reason the application was not filed on time.
The waiver does not replace the exemption application. The form says a completed application must be submitted together with it. The Assessor's organizational exemptions forms page also lists a Spanish version, 2026 Dispensa Del Plazo Para La Execión (Español), and DocuSign versions of the waiver.
Who needs to file FOR-144 V5?
Applicants for a Maricopa County property tax exemption whose application is filed on or after March 1 use this form. The form covers two groups, and you check one box:
- Personal exemptions: Widowed, Totally Disabled or Disabled Veteran.
- Organizational exemptions.
The form has a line marked Self Other, which lets the applicant show whether the person completing the form is the applicant or someone else; the form prints no further rule on who may sign for another person, so ask the Assessor if you are filing for someone else.
An application filed before March 1 is not the situation this form describes: its stated purpose is an application filed on or after March 1. The waiver is never submitted alone, because the form requires a completed exemption application to go with it.
When to file FOR-144 V5
Submit the waiver whenever your exemption application is filed on or after March 1. The form states that a completed application must be submitted along with the waiver by September 1.
The form sets no other date. It is completed on the date you enter in the Date field at the top and signed with its own date at the bottom, so use the day you actually prepare it. The reason for not filing timely is written on the lines provided and goes in with the application, not afterward.
Documents you need
- A completed exemption application, personal or organizational, which must be submitted along with the waiver by September 1.
- Supporting documents for the exemption application: the form says to return the waiver and completed application with supporting documents to the Assessor's office.
How to fill out FOR-144 V5
Check the exemption type
At the top, check one: Personal (Widowed/Totally Disabled/Disabled Veteran) or Organizational. This choice also tells you which attention line, PE or OE, to use if you mail the package.
Enter the date and parcel number
Write today's date in Date and the Parcel or Account Number of the property the exemption applies to.
Enter the applicant's name
In Applicant Name, write the name of the person or organization applying for the exemption.
Enter the mailing address
Fill in Mailing Address, City and Zip so the Assessor can reach the applicant.
Add phone, email and Self/Other
Enter the Phone and E-Mail, then complete the Self Other line as the form asks.
Explain the reason for filing late
In Reason for not filing timely, state why the exemption application was not filed before March 1. Three lines are provided.
Print your name and sign
At the bottom, enter Print Name, sign on Signature and add the Date. This is the request that the Maricopa County Board of Supervisors redeem the waiver under A.R.S. § 42-11153.
Review, download and assemble the package
Check that every line is complete, then download or print the completed PDF from FillingPDF. Attach the completed exemption application and supporting documents, and submit everything by September 1 through one of the channels described under How to submit.
How to submit FOR-144 V5
The form lists three ways to return the waiver and the completed application with supporting documents: online, by email, or by mail or in person.
- File Online: visit the Assessor's website at mcassessor.maricopa.gov.
- Email: send to [email protected] or [email protected].
- Mail or drop off in person: Attn: PE (for Personal) or OE (for Organizational), Maricopa County Assessor, 301 W Jefferson St, Phoenix, AZ 85003.
Whichever channel you use, send the signed waiver and the completed exemption application together, with supporting documents, by September 1. FillingPDF lets you fill out and download the PDF; submission follows the Assessor's channels above.
Common mistakes to avoid
- Submitting the waiver without the completed exemption application; the form says the completed application must accompany it.
- Sending the waiver and application after September 1, the date printed on the form.
- Checking neither exemption type, or the wrong one, when the form asks you to check one: Personal or Organizational.
- Leaving the reason for not filing timely blank; the form provides lines for it.
- Mailing the package without the attention line: use Attn: PE for Personal or OE for Organizational.
- Omitting the parcel or account number at the top of the form.
- Leaving the Print Name, Signature or Date lines at the bottom empty; the request to the Board of Supervisors is made through them.
