Fillable IRS Form 872‑B (Consent to Extend the Time to File)

Form 872‑B is the IRS consent document that allows a fiduciary (executor, administrator, trustee, etc.) to request an extension of time to file a tax return for a decedent’s estate or trust. The form must be signed by the fiduciary and, when applicable, by the corporate officer.

What Is IRS Form 872‑B?

This fillable PDF is used to obtain the IRS’s permission to extend the filing deadline for estate and trust income tax returns (Form 1041). It is often filed together with Form 56, Notice Concerning Fiduciary Relationship.

How to Fill Out Form 872‑B Online

Instead of downloading the PDF and opening a separate editor, simply click the "Fill out this form" button on this page. The Formize PDF Filler will load in your browser, letting you complete every field, add signatures, and save or submit the document directly.

Common Mistakes & Tips

  • Missing signatures: Every required signature line must be completed; corporate filings need the officer’s title.
  • Incorrect dates: Use the date the form is signed, not the date the extension is requested.
  • Wrong tax year: Verify the tax year on the top of the form matches the return you are extending.

Who Needs to Sign the Form?

If you are acting as a fiduciary, you must sign and attach Form 56 (unless already filed). For corporations, the form must be signed by an authorized officer with title included.

    No. Form 872‑B is a consent form and does not require a filing fee.

  • How long does the IRS have to approve the extension?
