IRS Form 4768 Instructions

If you’re an executor who must file a federal estate tax return, it may take a long time to distribute the decedent’s taxable estate. In many cases, this process goes much further than the normal due date of the return. Fortunately, the Internal Revenue Service allows taxpayers to file an estate tax extension using IRS Form 4768.

In this article, we’ll walk through this tax form and answer some frequently asked questions about estate taxes.

How do I complete IRS Form 4768?

This one-page tax form contains four parts:

We’ll walk through each part, step by step.

Part I: Identification

In this section, we’ll provide information about:

  • The decedent
  • The estate
  • The executor of the estate

Line 1: Beginning at the top, enter the decedent’s first name, middle initial, and last name, followed by the decedent’s date of death.

Line 2: Just below, enter the name of the executor, name of the application filer (if not the executor), followed by the decedent’s Social Security number. If the executor and the filer are the same person, leave the middle field blank.

Line 3: On the third line, enter the executor’s address (street name and number), followed by the estate tax return’s due date. If you are not sure about the due date, see the FAQ section.

Line 4: At the bottom of Part I, enter the city, state, and zip code for the executor, the decedent’s domicile (county, state, and zip code), and a daytime telephone number for the executor.

Part II: Extension of Time To File Form 706, 706-A, 706-NA, or 706-QDT (Section 6081)

In Part II, we’ll provide information about the tax return and reasons to request an extension.

Form for which extension of time to file is being requested

At the top of Part II, indicate which type of tax return for which you are requesting an extension:

  • IRS Form 706: United States Estate (and Generation-Skipping Transfer) Tax Return
  • IRS Form 706-A: United States Additional Estate Tax Return
  • IRS Form 706-NA: United States Estate (and Generation-Skipping Transfer) Tax Return, Estate of nonresident not a citizen of the United States
  • IRS Form 706-QDT: United States Estate Tax Return for Qualified Domestic Trusts

Below this section, there are three types of extensions that you might consider.

Automatic extension

Upon request, the IRS grants an automatic six-month extension of time, as long as the filing deadline has not already passed when the request is submitted.

If you are requesting an automatic extension, select this box and move down to Part III (if necessary), or Part IV.

If granted, the IRS will not contact you. Simply keep a completed copy of your extension request with your records.

part II, extension of time to file

Extension for cause/Form 4768 not filed in time for automatic extension

Check this box if you are applying for an extension, but the filing deadline has already passed. You must attach a statement explaining the following:

  • Why you did not timely request an automatic extension of time,
  • Why it was impossible or impractical to file the return by the due date, and
  • Specific reasons why you have good and sufficient cause for failing to timely request an automatic extension.

If approved, the six month extension for cause runs from the original due date of the return, not the date that you filed Form 4768 or the date of approval. Keep a completed copy of your extension request in your records.

Additional extension

In general, only an executor who is located outside the United States may request an additional extension of time beyond the six-month period after the original due date. To do this, you must check the box and provide a written explanation why it is impossible or impractical to file this return by the filing date.

The IRS encourages executors who may need additional time to separately request an automatic extension first, before the due date. From there, the executor can request the additional extension.

You cannot combine both an automatic extension and an additional extension on the same Form 4768.

Part III: Extension of Time To Pay (Section 6161)

Internal Revenue Code Section 6161 allows for an extension of time to pay estate tax or generation-skipping transfer tax liabilities, provided the executor can show reasonable cause.

The IRS can approve extensions for up to one year at a time, up to the following maximums:

  • Extension of time to pay: 10 years
  • Extension of time to pay a deficiency: 4 years

To receive an extension for payment, you must provide a detailed explanation and demonstrate good cause in a written statement. Submit this statement as an attachment to your completed form.

Types of reasonable cause

The IRS form instructions indicate the following as examples of reasonable cause:

  • Estate has sufficient liquid assets to pay taxes due. However, the assets are located in several jurisdictions, and the executor cannot readily collect them with reasonable effort
  • A substantial part of the estate consists of assets with rights to future payments. These assets cannot be liquidated or borrowed against without causing significant harm to the estate.
  • Estate includes a claim to substantial assets that are subject to litigation. The size of the gross estate is unascertainable on the due date
  • Estate doesn’t have sufficient funds, even though the executor has made reasonable efforts to convert assets into cash.

In addition to your attached written statement, you must:

  • Enter your requested extension date (not to exceed 12 months)
  • Check the appropriate box(es)

If the taxes cannot be determined because the gross estate’s size is unascertainable, check the appropriate box, then enter ‘0’ on Part IV, Line 3.

Also, check the appropriate box based upon the type of request. There are four possible boxes:

  • The request is for the tax that will be due when the original return is filed
  • The request is for the tax that will be due as part of an amended return or supplemental return
  • The request is for additional taxes due as part of an IRS examination
  • The request is for a Section 6166 installment payment

Interest on outstanding balances

Even with an approved extension, interest will accrue on any outstanding balance after the original due date. The IRS will calculate interest based upon the prevailing interest rate and outstanding balance due.

Part IV: Payment To Accompany Extension Request

Generally, the IRS will only grant an extension of time to pay for the amount of cash shortage in the decedent’s estate.

Line 1: Amount of estate and GST tax estimated to be due

In Line 1, estimate the amount of estate and/or generation-skipping transfer tax (GST tax) due.

Line 2: Amount of cash shortage

Indicate the amount of cash shortage. You must include a statement of assets already distributed. Also, if applicable, include a plan for partial payments during the extension period.

Line 3: Balance due

Subtract Line 2 from Line 1. This represents the balance due with your completed Form 4768. Please note that any submitted payment will not be refunded if there is a remaining tax liability, even if the payment exceeds the non-deferred liability amount.

Instead, the excess payment will be applied to other tax liabilities under IRC Sections 6402 and 6403.
