Yes.
Death proceeds received by individuals are wholly tax-exempt whether received from group permanent or group term insurance.1 Where group term life insurance coverage is provided to domestic partners of employees by an employer, death proceeds paid on the death of a domestic partner are excluded from income under IRC Section 101.2 The same rules as are applicable to proceeds under individual policies generally apply ( Q 63 to Q 71). Special rules apply if insurance is payable under a qualified pension or profit sharing plan ( Q 3969, Q 3970).
