Overview

The estate tax is a transfer tax on the value of the decedent's estate before distribution to any beneficiary.

Massachusetts estate tax returns are required if the gross estate, plus adjusted taxable gifts (computed using the Internal Revenue Code in effect on December 31, 2000), exceeds the filling threshold as follows:

  • For decedents dying on or after January 1, 2016 with a gross estate of more than $1,000,000 
  • For decedents dying on or after January 1, 2023 with a gross estate of more than $2,000,000.

Estates of decedents who died on or after January 1, 2023, are allowed a credit of $99,600 to reduce the amount of the estate tax. See MGL ch. 65C, § 2A(f).

Changes to the federal estate tax law after December 31, 2000 have no impact on the Massachusetts estate tax.

Filing and Payment Information

Who must file, and how is it done?

For dates of death on or after January 1, 2006 and before January 1, 2023, the personal representative of a decedent who was a domiciliary of Massachusetts must file a Massachusetts Estate Tax Return (Form M-706) if the gross value of the decedent’s estate, plus adjusted taxable gifts, exceeds $1,000,000.

For dates of death on or after January 1, 2023, the personal representative of a decedent who was a domiciliary of Massachusetts must file a Massachusetts Estate Tax Return (Form M-706) if the gross value of the decedent’s estate, plus adjusted taxable gifts, exceeds $2,000,000.

The filing requirement for a nonresident decedent who owned or transferred real estate or tangible personal property located in Massachusetts is the same as for a resident and is based on their total worldwide estate plus adjusted taxable gifts. The personal representative of the estate of a nonresident decedent who owned or transferred real estate or tangible personal property located in Massachusetts must file a Massachusetts Nonresident Decedent Affidavit (Form M-NRA) with Form M-706. They can be filed using MassTaxConnect.

A personal representative may be held personally liable for payment of any tax shown on the return if it is not otherwise paid.  Massachusetts Estate Tax Return (Form M-706) can be filed by entering information online with MassTaxConnectPayments can also be made online, including extension payments.

Filing and paying with MassTaxConnect will result in faster processing, a quicker generation of the Massachusetts Estate Tax Closing Letter and Certificate Releasing Massachusetts Estate Lien. The return and tax payment can also be sent to:

Massachusetts Department of Revenue
P.O. Box 7023
Boston, MA 02204

Mailing the M-706 and payments may delay the processing and review process.

Who is considered the executor for purposes of the Massachusetts estate tax?

A personal representative is the person appointed, qualified and acting  within Massachusetts. If there is no personal representative appointed, qualified and acting within Massachusetts, then any person in actual or constructive possession of any property of the decedent. 

When must the return be filed?

If the gross estate exceeds the filing threshold for the year of death, the return and tax payment are due nine months after the date of the decedent's death.

When must the return be filed?

If the gross estate exceeds the filing threshold for the year of death, the return and tax payment are due nine months after the date of the decedent's death.

Can an extension of time to file be granted?

As of December 5, 2016, all filers of estate tax returns are automatically granted a six-month extension of time to file their tax returns provided they have paid at least 80% of the total amount of tax ultimately due on or before the payment due date. Go to TIR 16-10: Simplified Extension Process for Individuals, Fiduciaries, Partnerships, and Estates for more information.Failure to pay at least 80% of the amount of tax finally determined to be due on or before the due date will void the automatic extension of time to file. The return will be subject to the late filing penalty and, possibly, the late payment penalty. Interest is due on any unpaid tax from the original due date.

Please see "What happens if the return is late?" for more information on interest rates.

Can an extension of the payment due date be granted?

By filing a Massachusetts Estate Tax Extension Application (Form M-4768), an extension of time to pay may be granted for a reasonable period, not to exceed six months for each request. This request must be received on or before the original filing date (9 months from the date of death). To align with the automatic extension of time to file, the initial request for an extension of time to pay will also be treated as an extension of time to file. At the end of the initial six-month period an estate must submit a request for an extension of time to pay for each additional six-month period on or before the extended due date.

When an extension of time to pay is granted, interest will still accrue on any unpaid tax due from the original due date. An extension is granted only for undue hardship/reasonable cause. An extension of up to three years from the original due date may be granted upon a showing of undue hardship/reasonable cause.

What happens if the return is late?

Failure to file a required return within nine months from the date of death or within an approved period of extension will result in penalties and interest being applied at the following rates:

  • Late Filing Penalty - 1% per month (or fraction thereof) to a maximum of 25% of the tax as finally determined to be due.
  • Late Payment Penalty - 1% per month (or fraction thereof) to a maximum of 25% of the tax reported as due on the return.
  • Interest - The Massachusetts interest rates for underpayments and overpayments of state taxes can change each calendar quarter. If you wish to obtain information on these rates, please call DOR's Contact Center at (617) 887-6367 or toll-free in Massachusetts at (800) 392-6089. 

There are other consequences in addition to these penalty and interest charges. At the time of death, a lien automatically arises by operation of law on all real estate owned by a decedent, either alone or jointly held. Failure to file a Form M-706, Massachusetts Estate Tax Return (and a Form M-NRAMassachusetts Nonresident Decedent Affidavit, for nonresidents) will prevent the issuance of a Certificate Releasing Massachusetts Estate Lien (formerly Form M-792 ). A release of lien is necessary to obtain clear title and to sell or otherwise transfer ownership of the real estate.

When is a release of lien necessary?

For dates of death on or after January 1, 1997, if the amount of the gross estate requires the filing of a Massachusetts estate tax return, a Certificate Releasing Massachusetts Estate Lien is necessary for:

  • Real estate owned jointly or as tenants by the entirety
  • Real estate held in trust and
  • Other real estate that is not part of the probate inventory but is includible in the gross estate.

probate and nonprobate real estate if there is a sale pending or mortgage commitment and no closing letter has been issued.

If the return was filed previously, the taxpayer should forward a copy of the purchase and sale agreement or mortgage commitment and indicate that a return was filed in order to expedite issuance of Certificate Releasing Massachusetts Estate Lien.

Where the return has not yet been filed, an Application for Certificate Releasing Massachusetts Estate Tax Lien (Form M-4422) may be filed, provided both of the following conditions exist:

  • The transaction is occurring sooner than nine months after the decedent's death, or later than nine months if the estate is filing during the time allowed by an approved extension of time to file Form M-706; and
  • There is an executed purchase and sale agreement (or mortgage commitment) for real estate which is includible in the decedent's estate.

The Form M-4422 was revised and can be filed by entering information electronically through MassTaxConnect. Filing through MassTaxConnect will result in faster processing and quicker release of the Certificate Releasing Massachusetts Estate Lien. By filing on MassTaxConnect, the estate can access and print the Certificate Releasing Massachusetts Estate Lien from its MassTaxConnect account.

The application must be filed with:

  • An attested copy of the deed,
  • A copy of the purchase and sale agreement or mortgage commitment,
  • Payment of the estimated amount of the tax due, and
  • A copy of the death certificate.

A completed Form M-706 (and a Form M-NRA for nonresidents) still must be filed within nine months of the date of death or during the time allowed by an extension of time to file Form M-706.

How can a personal representative or other fiduciary obtain a release of lien on real estate when there is no Massachusetts estate tax filing requirement?

For estates of decedents dying on or after January 1, 1997, an affidavit of the personal representative is required to release the gross estate of the lien for estates that are less than the Massachusetts filing requirement for the year of death. The affidavit must be:

  • Subscribed to under the pains and penalties of perjury
  • Recorded in the registry of deeds and
  • Accurately stating that the gross estate of the decedent does not necessitate a Massachusetts estate tax filing.

DOR does not publish blank affidavits for filing in the registry of deeds.

For the estates of decedents that equal or exceed the applicable threshold triggering a Massachusetts filing requirement, the Commissioner of Revenue will release the lien with respect to property if the Commissioner is satisfied that the collection of the tax will not be jeopardized. The Commissioner will release the lien by issuing Certificate Releasing Massachusetts Estate Lien.

What documents must accompany Form M-706?

Various documents must be filed with the return. Failure to file these documents will delay the return's processing. The major supporting documents required to be filed with the Massachusetts Estate Tax Return (Form M-706), where applicable, are:

  • An executed copy of the federal estate tax return, Form 706 with a revision date of July 1999, including the death certificate and all schedules, as described in General Instructions, Section I, Supplemental Documents of the Form 706 instructions (with a revision date of July 1999) and in the instructions for various schedules of Form 706. All estates must file a copy of the federal Form 706 with a revision date of July 1999 when filing Form M-706. If the estate is required to file a current federal Form 706, include a copy of that return, in addition to Form 706 (with a revision date of July 1999) and the Form M-706. If some or all of the schedules for the July 1999 revision of Form 706 and the current version of Form 706 are the same, submit one set of schedules.
  • A Federal Closing Letter must be submitted to DOR within two months of receipt if the filing of Form 706 is required. This includes both the federal letter of acceptance and line adjustments, if any. Copies of federal changes must be accompanied by an amended Form M-706. No Massachusetts Estate Closing Letter will be issued without a copy of the Federal Closing Letter.
  • A Massachusetts Nonresident Decedent Affidavit (Form M-NRA) for the estates of nonresident decedents.

How must property included in the estate be valued?

All property includible in the gross estate is reported at its fair market value on the date of the decedent's death or on the alternate valuation date six months later. Special Internal Revenue Service rules apply to the Qualified Family-Owned Business Interest Deduction (Schedule T on the July 1999 revision of the federal Form 706) and the Qualified Conservation Easement Exclusion (Schedule U on the July 1999 revision of the federal Form 706). For more information on these rules, please contact the Estate Tax Unit at (617) 887-6930.

What property must be included in the gross estate?

The gross estate includes all property in which the decedent had an interest. It also includes:

  • Certain transfers made during the decedent's life without an adequate and full consideration in money or money's worth
  • Annuities
  • Joint estates with right of survivorship
  • Tenancies by the entirety
  • Life insurance proceeds (even though payable to beneficiaries other than the estate)
  • Property over which the decedent possessed a general power of appointment
  • Dower or curtesy (or statutory estate) of the surviving spouse
  • Community property to the extent of the decedent's interest as defined by applicable law.

How is the Massachusetts estate tax computed?

The Massachusetts estate tax for the estates of residents and nonresidents is computed with reference to the allowable federal estate tax credit for state death taxes formerly allowed in the Internal Revenue Code in effect on December 31, 2000. If an estate consists solely of property subject to Massachusetts estate taxation, it pays to Massachusetts an amount equal to the federal credit for state death taxes computed using the Internal Revenue Code in effect on December 31, 2000. For estates of decedents dying on or after January 1, 2023, the Massachusetts estate tax is reduced by a credit of $99,600. The federal rate table used to compute the credit for state death taxes is set out in the next section.

For the estate of a decedent who died on or after January 1, 2006, and before January 1, 2023, and who was a resident of Massachusetts who owned or transferred real estate or tangible personal property located outside of Massachusetts, the Massachusetts estate tax is the amount of the federal credit for state death taxes minus the lesser of:

  • The total of the amount of all estate, inheritance, legacy, and succession taxes actually paid to other states for property owned by the decedent or subject to those taxes in connection with the estate; or
  • The amount equal to the proportion of the allowable credit as the value of the properties taxable by other states bears to the value of the entire federal gross estate wherever situated. This calculation is made as follows:
    • (Gross value of property taxed by other states ÷ Federal gross estate) × Credit for state death taxes

For the estate of a decedent who died on or after January 1, 2023, and who was a resident of Massachusetts who owned or transferred real estate or tangible personal property located outside of Massachusetts, the Massachusetts estate tax is the amount of the federal credit for state death taxes minus the amount equal to the proportion of the allowable credit as the value of the properties located outside of Massachusetts bears to the value of the entire federal gross estate wherever situated minus a $99,600 credit. This calculation is made as follows:

  • Prorated Credit = (Gross value of real estate and tangible properties located outside of Massachusetts ÷ Federal gross estate) × Credit for state death taxes
  • Estate Tax = Credit for state death taxes – Prorated Credit - $99,600

In the case of a nonresident of Massachusetts who owned or transferred real estate or tangible personal property located in Massachusetts, use the Massachusetts Estate Tax Return (Form M-706) to compute the amount payable to Massachusetts.

The amount of the Massachusetts nonresident estate tax is the proportion of the allowable credit from the federal estate tax return that the gross value of the Massachusetts property bears to the entire federal gross estate wherever situated. This calculation is made as follows:

  • Estate tax = (Gross value of real property and tangible personal property in Massachusetts ÷ Federal gross estate) × Credit for state death taxes.

Can the tax liability be adjusted after Form M-706 is filed?

A taxpayer who believes the assessed tax liability exceeds the amount properly due may submit an amended return within

  • 3 years from the due date of the return or the filing date, whichever is later, taking into account any extension of time for filing the return, or
  • 2 years from the date the tax was assessed, or
  • 1 year from the date the tax was paid

whichever occurs latest.

An estate may be a party to litigation that may reduce the amount of the Massachusetts estate tax and the litigation will not be resolved before the expiration of the statutory period allowed for filing an application for abatement. In those cases, an estate cannot file a substantiated abatement because the result of the litigation is unknown. To preserve its ability to claim additional debts and expenses related to the litigation, the estate may request that DOR extend the period for the assessment of estate tax. The statute extension also extends the period of time to file an application for abatement, or an amended return. A statute date is extended using a Form A-37, Consent Extending Period for Assessment of Estate Tax. Such an extension request must be renewed annually with an update from the estate representative to DOR on the status of the pending litigation. A taxpayer also may request settlement consideration by filing an Appeals Form DR-1 with DOR's Office of Appeals. For more information about the appeals process, go to A Guide to the Department of Revenue: Your Taxpayer Bill of Rights.

*The "adjusted taxable estate" used in determining the allowable credit for state death taxes in the above table is the federal taxable estate (total federal gross estate minus allowable federal deductions) less $60,000.

There is no federal credit for state death taxes if the "adjusted taxable estate" is $40,000 or less.

For estates of decedents who died in 2023 or after

Example 1

Facts. A decedent dies in 2023 with a gross estate of $2,580,000.

  • had not made any gifts during his lifetime and
  • did not own any property outside of Massachusetts.

The deductions of the estate are $80,000. The taxable estate is $2,500,000 ($2,580,000 less $80,000).

Computation of the credit for state death taxes for Massachusetts estate tax purposes. The computation is as follows:

  1. The adjusted taxable estate is $2,440,000 ($2,500,000 less $60,000).
  2.  An adjusted taxable estate of $2,440,000 is within the range of the numbers on the eleventh line (from chart): $2,040,000 to $2,540,000
  3. The federal credit on the first $2,040,000 is $106,800.
  4. The credit on any amount in excess of $2,040,000 and up to $2,540,000 is computed at the rate of 8 percent.
  5. In this example, $400,000 is in excess of $2,040,000 ($2,440,000 less $2,040,000).
  6. The credit on $400,000 is $32,000 ($400,000 × .08).
  7. The maximum credit for state death taxes is $138,800 ($106,800 plus $32,000).
  8. The Massachusetts estate tax is $39,200 ($138,800 less $99,600 – The Massachusetts Estate Tax Credit).

For estates of decedents who died before 2023

Example 2

Facts. A decedent dies in 2021 with a gross estate of $1,580,000. The decedent

  • had not made any gifts during his lifetime and
  • did not own any property outside of Massachusetts.

The deductions of the estate are $80,000. The taxable estate is $1,500,000 ($1,580,000 less $80,000).

Computation of the credit for state death taxes for Massachusetts estate tax purposes. The maximum federal credit for state death taxes is $64,400. The computation is as follows:

  1. The adjusted taxable estate is $1,440,000 ($1,500,000 less $60,000).
  2.  An adjusted taxable estate of $1,440,000 is within the range of the numbers on the ninth line (from chart): $1,040,000 to $1,540,000.
  3. The credit on the first $1,040,000 is $38,800.
  4. The credit on any amount in excess of $1,040,000 and up to $1,540,000 is computed at the rate of 6.4 percent.
  5. In this example, $400,000 is in excess of $1,040,000 ($1,440,000 less $1,040,000).
  6. The credit on $400,000 is $25,600 ($400,000 × .064).
  7. The maximum credit for state death taxes is $64,400 ($38,800 plus $25,600).

The Massachusetts estate tax is equal to the amount of the maximum credit for state death taxes. It is computed using the Internal Revenue Code § 2011 in effect on December 31, 2000.

In some estates, the federal estate tax less the unified credit (applicable credit amount) computed using the Internal Revenue Code in effect on December 31, 2000, is less than the credit for state death taxes. In those situations, the credit for state death taxes is limited to the amount of the federal estate tax less the unified credit (applicable credit amount). In Example 1, the federal estate tax less the unified credit (applicable credit amount) is $210,000. Since the credit for state death taxes in Example 1 is smaller than the federal estate tax less the unified credit, the limitation does not apply. Example 2 illustrates the tax computation for an estate in which the limitation is applicable.

Example 3

Facts. A decedent dies in 2021 with a gross estate of $1,100,000. The decedent

  • had not made any gifts during his lifetime and
  • did not own any property outside of Massachusetts.

The deductions of the estate are $50,000. The taxable estate is $1,050,000 ($1,100,000 less $50,000).

Step 1: Computation of the credit for state death taxes for Massachusetts estate tax purposes. The maximum federal credit for state death taxes is $36,000. The computation is as follows:

  1. The adjusted taxable estate is $990,000 ($1,050,000 less $60,000).
  2. An adjusted taxable estate of $990,000 is within the range of numbers on the eighth line (from chart): $840,000 to $1,040,000.
  3. The credit on the first $840,000 is $27,600.
  4. The credit on any amount in excess of $840,000 and up to $1,040,000 is computed at the rate of 5.6 percent.
  5. In this example, $150,000 is in excess of $840,000 ($990,000 less $840,000).
  6. The credit on $150,000 is $8,400 ($150,000 × .056).
  7. The maximum credit for state death taxes is $36,000 ($27,600 plus $8,400).
Table A - Unifiled Rate Schedule for estate tax


Step 2: Computation of the federal estate tax using the Internal Revenue Code in effect on December 31, 2000. The federal estate tax is $20,500. It is computed using Table A, Unified Rate Schedule, from page 12 of the July 1999 revision of the instructions for Form 706 and the unified credit (applicable credit amount) for 2006 and after from the instructions for line 11 from page 4 of the July 1999 revision of the instructions for Form 706. The computation is as follows:

  1. A taxable estate of $1,050,000 is within the range of the numbers on the twelfth line of Table A: $1,000,000 to $1,250,000.
  2. The tax on the first $1,000,000 is $345,800.
  3. The tax on any amount in excess of $1,000,000 and up to $1,250,000 is computed at the rate of 41 percent.
  4. In this example, $50,000 is in excess of $1,000,000 ($1,050,000 less $1,000,000).
  5. The tax on $50,000 is $20,500 ($50,000 × .41).
  6. The tentative tax computed by using Table A is $366,300 ($345,800 plus $20,500).
  7. The tentative tax computed using Table A is reduced by the unified credit (applicable credit amount). For deaths occurring in 2006 and after, the unified credit (applicable credit amount) from the instructions for line 11 is $345,800. This is an applicable exclusion amount of $1,000,000.
  8. The federal estate tax after reduction by the amount of the unified credit (applicable credit amount) is $20,500 ($366,300 less $345,800).

Step 3: Computation of the amount of the credit for state death taxes payable to Massachusetts. The amount of the credit for state death taxes cannot be more than the federal estate tax less the unified credit (applicable credit amount). The computation of the amount payable to Massachusetts is determined as follows:

  1. The amount of the credit for state death taxes from step 1, line 7 of this example is $36,000.
  2. The amount of the federal estate tax after reduction by the amount of the unified credit (applicable credit amount) from step 2, line 8 of this example is $20,500.
  3. Since the amount of the federal estate tax is less than the credit for state death taxes, the amount of the credit for state death taxes is limited to the amount of the federal estate tax. Therefore, the amount of the credit for state death taxes payable to Massachusetts is reduced to $20,500.

In some estates, the decedent made lifetime gifts that reduced the decedent’s gross estate at death to less than $1,000,000. However, a Massachusetts estate tax return is required if the gross estate at death plus adjusted taxable lifetime gifts, computed using the Internal Revenue Code in effect on December 31, 2000, exceeds $1,000,000. Example 3 illustrates the tax computation for an estate in which the gross estate at death is less than $1,000,000, but the sum of the gross estate at death and the adjusted taxable lifetime gifts exceeds $1,000,000.   

Example 4

Facts. A decedent dies in 2021 with a gross estate of $990,000. The decedent

  • did not own any property outside of Massachusetts and
  • made $1,000,000 of adjusted taxable lifetime gifts.

The allowable deductions of the estate are $50,000. While the decedent’s gross estate at death is less than $1,000,000, the sum of the decedent’s gross estate at death and the adjusted taxable lifetime gifts is $1,990,000 ($990,000 plus $1,000,000). Therefore, a Massachusetts estate tax return is required because the sum of the decedent’s gross estate at death and the adjusted taxable lifetime gifts exceeds $1,000,000. The Massachusetts taxable estate is $940,000 ($990,000 less $50,000).

Step 1: Computation of the credit for state death taxes for Massachusetts estate tax purposes. The maximum federal credit for state death taxes is $29,840. The computation is as follows:

  1. The adjusted taxable estate is $880,000 ($940,000 less $60,000).
  2. An adjusted taxable estate of $880,000 is within the range of the numbers on the eighth line: $840,000 to $1,040,000.
  3. The credit on the first $840,000 is $27,600.
  4. The credit on any amount in excess of $840,000 up to $1,040,000 is computed at the rate of 5.6 percent.
  5. In this example, $40,000 is in excess of $840,000 ($880,000 less $840,000).
  6. The credit on $40,000 is $2,240 ($40,000 x .056).
  7. The maximum credit for state death taxes is $29,840 ($27,600 plus $2,240).

Step 2: Computation of the federal estate tax using the Internal Revenue Code in effect on December 31, 2000. The federal estate tax is $408,000. It is computed using Table A, Unified Rate Schedule, from page 12 of the July 1999 revision of the Instructions for Form 706 and the unified credit (applicable credit amount) for 2018 from the instructions for Line 11 from page 4 of the July 1999 revision of the Instructions for Form 706. Taxable estate is $1,940,000 ($990,000 - $50,000 + $1,000,000). The computation is as follows:

  1. A taxable estate of $1,940,000 is within the range of the numbers on the fourteenth line of Table A: $1,500,000 to $2,000,000.
  2. The tax on the first $1,500,000 is $555,800.
  3. The tax on any amount in excess of $1,500,000 up to $2,000,000 is computed at the rate of 45 percent.
  4. In this example, $440,000 is in excess of $1,500,000 ($1,940,000 less $1,500,000).
  5. The tax on $440,000 is $198,000 ($440,000 x .45).
  6. The tentative tax computed by using Table A is $753,800 ($555,800 plus $198,000).
  7. The tentative tax computed by using Table A is reduced by the unified credit (applicable credit amount). For deaths occurring in 2018, the unified credit (applicable credit amount) from the instructions for Line 11 is $345,800. This is an applicable exclusion amount of $1,000,000.
  8. The federal estate tax after reduction by the amount of the unified credit (applicable credit amount) is $408,000 ($753,800 less $345,800).

Step 3: Computation of the amount of the credit for state death taxes payable to Massachusetts. The amount of the credit for state death taxes that is payable to Massachusetts is $29,840. The credit for state death taxes is the lesser of the credit for state death taxes computed on the amount, less $60,000, entered on line 3 of the July 1999 revision of Form 706 and the federal estate tax, less the unified credit (applicable credit amount), entered on line 14 of the July 1999 revision of Form 706. The computation of the amount payable to Massachusetts is determined as follows:

  1. The amount of the credit for state death taxes from step 1, line 7 is $29,840.
  2. The amount of the federal estate tax after reduction by the amount of the unified credit (applicable credit amount) from step 2, line 8 is $408,000.
  3. Since the credit for state death taxes is less than the federal estate tax less the unified credit (applicable credit amount), the amount of the credit for state death taxes is limited to the credit for state death taxes computed on the amount, less $60,000, entered on line 3 of the July 1999 revision of Form 706. Therefore, the amount of the credit for state death taxes payable to Massachusetts is $29,840.
