Overview

Massachusetts Mutual Life Insurance Company (MassMutual) is one of the largest mutual life insurance companies in the United States, serving millions of policyholders. When a policyholder passes away, the beneficiary or estate representative must notify MassMutual to initiate the claim process for life insurance policies or annuities.

This guide covers MassMutual's death claim process, including the required documents, contact information, and what to expect regarding timelines.

Note on Retirement Plans: In 2020, MassMutual sold its retirement plan business (401(k), 403(b), etc.) to Empower. If the deceased held a workplace retirement account that was originally with MassMutual, you likely need to contact Empower instead.

This guide provides informational guidance only. It is not legal advice, and SwiftProbate is not a law firm. Laws and institutional procedures change — verify current requirements directly with MassMutual and consider consulting a qualified attorney.

Notification Process

How to Notify MassMutual of a Death

Step 1: Gather Initial Information

Before contacting MassMutual, have the following ready:

  • Decedent's full legal name and date of birth
  • Date of death
  • Social Security number
  • Policy or contract numbers (if known)
  • Your name and relationship to the decedent
  • Beneficiary information (if you are the beneficiary)

Step 2: Initiate the Claim

You can start the process online or by phone:

Option A: Online

Visit the MassMutual Death Claims page to start the notification process digitally.

Option B: Phone

Contact MassMutual's Customer Service Center:

  • Phone: (800) 272-2216
  • Hours: Mon–Fri, 8 AM – 8 PM ET

When you reach an agent, they will verify the policy details and initiate the claim packet request.

Step 3: Receive and Complete the Claim Packet

MassMutual will send a claim packet (via mail or email) containing the necessary forms. This typically includes a Claimant's Statement. Each beneficiary must usually complete their own statement.

Step 4: Submit Required Documents

Mail the completed forms and the certified death certificate to the address provided in the claim packet.

Standard Mailing Address:

MassMutual Life Insurance Company

1295 State Street

Springfield, MA 01111-0001

(Note: Always check the specific address listed on your claim forms, as some departments may use a specific PO Box.)

Step 5: Wait for Processing

After MassMutual receives your documents, they will review the claim.

  • Standard processing time: Approximately 10–15 business days after all documents are received in good order.
  • Complex claims: May take longer if the policy is within the contestability period (usually the first two years) or if the cause of death requires investigation.

Account Types

How MassMutual Handles Different Account Types

Life Insurance Policies

Beneficiaries file a claim to receive the death benefit. If there are multiple beneficiaries, each receives their share directly.

Timeline: 10–15 business days

Annuities

The death benefit depends on the contract terms. It may be a lump sum of the account value or a continuation of payments to a surviving spouse.

Timeline: 10–15 business days

MassMutual Ascend (formerly Great American Life)

If the policy is with MassMutual Ascend, the process is handled separately.

  • Phone: (800) 854-3649
  • Hours: Monday – Friday, 8 AM – 5 PM ET
  • Website: MassMutual Ascend Claims
  • Processing time: 5–10 business days

Workplace Retirement Plans (401k, 403b)

Most MassMutual retirement plans were acquired by Empower.

  • Action: Check the account statement. If it is now administered by Empower, contact them directly.

Disability Income Insurance

If the deceased had a disability policy, notify MassMutual to stop premium billing and potentially claim any final benefits or premium refunds.

Timeline: Varies

State Considerations

How Your State Affects the MassMutual Process

MassMutual operates nationally, but state laws impact the claims process:

  • Interest on Death Benefits: Many states require insurers to pay interest on the death benefit from the date of death until the date of payment.
  • Contestability Period: Usually 2 years. If death occurs within this window, MassMutual may investigate the medical history before paying.
  • Community Property: In states like CA, TX, and AZ, a spouse may have a claim to a portion of the policy proceeds even if not named as the beneficiary.

Tips & Pitfalls

Common Pitfalls and Tips

Check for "MassMutual Ascend"

MassMutual Ascend is a separate subsidiary. Check the policy logo carefully; if it says "Ascend," use their specific contact number ((800) 854-3649) to avoid delays.

The Contestability Period

If the policy was issued less than two years ago, MassMutual will likely request medical records to ensure the application was accurate. This is standard procedure, not a denial.

Multiple Beneficiaries

If there are multiple beneficiaries, MassMutual typically waits to receive claim forms from all named beneficiaries before releasing funds, though practices can vary. Encourage all beneficiaries to submit their forms quickly.

Interest Payments

In many cases, MassMutual will pay interest on the death benefit. This interest is taxable income, while the principal death benefit is generally tax-free.

Lost Policy?

You generally do not need the original physical policy to file a claim. MassMutual can look it up with the decedent's SSN.
