Important Information Regarding Estate Tax Forms

Massachusetts estate tax returns can be filed electronically though MassTaxConnect or by using the forms below. Please note: Be sure to use only the current versions of all forms available on this page as older versions with no barcode will not be accepted.

An “Amended return due to federal change,” oval has been added to the Form M-706 return.

Form M-4768 (extension of time to file) has been combined with M-4768A (extension of time to pay). The M-4768 was changed to be consistent with the Automatic 6 month extension that the other tax types use.  This was incorporated into one form to simplify the request for both an extension of time to file and extension of time to pay.  

Zero tax due extension requests are invalid. All extension of Time to File submissions must be accompanied by the estimated tax payment unless the estate is also requesting an extension of time to pay the estate tax.

Form M-792, Certificate Releasing Massachusetts Estate Tax Lien has been replaced with the new Certificate Releasing Massachusetts Estate Lien which the DOR will automatically generate from the information provided on Form M-706, Part 7, Real Estate Subject to Massachusetts Estate Tax Lien. 

The “Power of Attorney” section on Forms M-706 and M-4422 has been removed from those forms. Form M-2848, Power of Attorney and Declaration of Representative, must be submitted, if applicable, with those forms.
