Tax & estate planning guide
Using life insurance to help pay an Inheritance Tax bill
Life insurance does not reduce the value of an estate by itself. But appropriately structured cover can provide money when someone dies, helping beneficiaries or trustees meet an expected Inheritance Tax liability without relying entirely on the sale of estate assets.
The problem
An estate can be valuable without holding enough accessible cash.
HMRC normally requires Inheritance Tax to be paid by the end of the sixth month after the person dies, with interest potentially arising after that point. In many cases IHT must be dealt with before probate or confirmation allows the estate to be fully administered.
If much of the estate consists of a home, business interests or investments that the family does not want to sell quickly, finding cash for the tax can become an important estate-planning issue.
The policy does not remove the IHT liability; it can help provide the money needed to meet it.
Cover duration
Whole-of-life cover is often considered where the liability is expected to arise whenever death occurs.
Term assurance only covers a defined period. Whole-of-life insurance is designed to remain in force for life provided the policy conditions are met and required premiums are maintained.
That can make it relevant where the estate expects to retain a long-term IHT exposure. However, whole-of-life policies can be more expensive and policy structures, premium guarantees and investment elements vary.
The guarantees, premiums, underwriting, exclusions and conditions need to be understood.
Ownership
Writing suitable life cover in trust can be important.
If a policy is owned personally and its proceeds become payable to the estate, the proceeds themselves can affect the estate position and may also be tied up in estate administration.
A suitable trust can allow policy proceeds to be paid to trustees for the intended beneficiaries rather than first passing through the deceased's estate, subject to the trust and policy terms.
Trustees, beneficiaries, policy ownership and the legal and tax consequences must be considered. Legal or specialist tax advice may be required.
Calculating the need
The sum assured should relate to the expected liability.
An IHT estimate starts with the assets and liabilities expected to form part of the estate, then considers exemptions, the nil-rate band, residence nil-rate band where available, transferable allowances and relevant reliefs.
Estate value
Property, investments, cash, business interests and other assets may need to be considered.
Allowances
Available nil-rate bands and exemptions can materially change the expected liability.
Future growth
The estate and potential tax bill may change over time.
Existing planning
Gifts, trusts, reliefs and other insurance may alter the amount of additional cover required.
Ongoing planning
The expected tax bill can move while the insurance stays fixed.
Property and investment values can rise or fall, tax rules can change, gifts may be made and family circumstances can alter. A policy arranged years earlier may therefore no longer match the liability it was intended to fund.
Review the estate valuation, likely allowances, cover amount, ownership and trust arrangements periodically and after major changes.
It should be considered alongside wills, gifting, trusts, pensions, investment strategy and the individual's own need for financial security during life.
