The Life-Insurance Exemption: The Most Basic Structure in Succession Planning

"Cash left to my children is taxed — is insurance different?" We hear this question repeatedly from wealth holders approaching the question of succession. The short answer: life-insurance proceeds are within the scope of inheritance tax, yet they are treated differently from cash. Two structures create that difference — the exemption allowance and the nature of proceeds as the beneficiary's own property.

Death Benefits Are "Deemed Inherited Property"

The starting point is that life-insurance proceeds received by a beneficiary upon the death of the insured are included in the scope of inheritance tax as "deemed inherited property" (Inheritance Tax Act, Art. 3(1)(i)). Where the deceased paid the premiums, the proceeds are brought into the taxable estate value even though they are not part of the estate itself. The notion that "insurance is therefore tax-free" is inaccurate from the outset.

Exemption Allowance = ¥5 million × Number of Statutory Heirs

On top of this, life-insurance proceeds carry their own exemption. Article 12(1)(vi) of the Inheritance Tax Act excludes the following amount from the taxable estate value.

The "number of statutory heirs" here is the figure defined in Article 15(2). With three statutory heirs, for example, up to ¥15 million of life-insurance proceeds is exempt. A separate allowance of the same size applies to death retirement benefits.

The "Beneficiary's Own Property" Character

Insurance proceeds also have a quality that sets them apart from estate division. Article 42 of the Insurance Act provides that where the beneficiary is someone other than a party to the contract, that beneficiary nonetheless enjoys the benefit of the contract as of right. Proceeds with a named beneficiary are acquired by that beneficiary in their own right, and are understood as distinct from estate property subject to a division agreement. This matters when one wishes to fix in advance who receives how much.

Note: Retirement Pay Is a Different Tax

A caution: a retirement payment an owner takes for themselves falls under income tax, not inheritance tax. Article 30 of the Income Tax Act computes retirement income as "(retirement allowance − retirement income deduction) × one-half," with the deduction set at ¥400,000 per year for service of 20 years or less and ¥700,000 per year for the portion beyond 20 years. This belongs to a different system from the inheritance-tax exemption, and the two should not be conflated.

Treat It as a Structure

What we can offer as general information ends here — the framework of the rules. Whom to name as beneficiary, and which assets to map onto which allowance, depends on each family's composition and asset position. Knowing the exemption exists, and mapping your own statutory-heir count and assets onto a single diagram, is the first step toward seeing succession as a structure.
