141AZEXT: Application for Filing Extension for Fiduciary Returns (2024)

Who files this form

Form 141AZ EXT is for fiduciaries requesting an extension to file Arizona Form 141AZ for an estate or trust.

Arizona grants an automatic 5½-month filing extension to fiduciaries filing Form 141AZ. Arizona also accepts a valid federal extension for the period it covers. If you are using a federal extension, this form can be used to send your Arizona extension payment.

When it's due

For tax year 2024 calendar-year filers:

• April 15, 2025: Your filing extension request must be postmarked by this date.
• September 30, 2025: Extended return due date under the automatic 5½-month fiduciary filing extension.
• October 15, 2025: Extended return due date for a Qualified Funeral Trust using a federal extension on Form 7004, which allows a 6-month extension.

What you'll need

Have the following information ready to complete the form:

• Estate or trust name and EIN. The form directs grantor trusts to see the instructions for the EIN field, but those instructions are not included here.
• Fiduciary name, title and mailing address.
• Daytime phone number for the fiduciary or representative, including area code.
• Calendar-year or fiscal-year information. Fiscal-year filers must enter their taxable year-end date and 5½-month extended due date.
• Tax liability for 2024, which may be estimated, and Arizona estimated tax payments for 2024.

If sending a payment, include it with Form 141AZ EXT.

How to file

1. Enter the estate or trust and fiduciary information and identify the tax year.
2. Check one extension option: calendar-year filer, fiscal-year filer, or use of a federal extension with this form to send an Arizona extension payment.
3. Enter your 2024 tax liability on line 1 and Arizona estimated tax payments for 2024 on line 2. Subtract line 2 from line 1 to find the balance of tax on line 3.
4. Enter your payment amount on line 4, rounded to the nearest dollar.

Make your check payable to Arizona Department of Revenue. Write the estate or trust’s name, EIN and 2024 141AZ extension on the payment. Include the payment with the form.
