When Should You Start Inheritance Tax Planning? A Guide for UK Homeowners and Families

There is no single age at which everyone should begin inheritance tax planning.

A homeowner aged 45 with substantial property equity, investments and children may have more reason to review their position than a retiree aged 75 whose estate falls comfortably within the available allowances.

Age can influence the type of planning that is appropriate, but it does not determine whether inheritance tax will be payable.

The key factors are the value of the estate, the intended beneficiaries, the available exemptions and reliefs, and the person's financial needs.

In Your 40s and 50s: Establish the Foundations

For many families, this is a sensible time to ensure basic estate planning arrangements are in place.

Priorities may include making or reviewing a will, considering guardianship arrangements for minor children, understanding property ownership and checking pension beneficiary nominations.

Inheritance tax may not be an immediate concern.

However, rising property values, business growth or an expected inheritance can make an early estimate worthwhile.

The objective at this stage is usually to build a clear picture rather than commit to irreversible transfers.

In Your 60s: Review the Position Around Retirement

Retirement often changes the balance between income, capital and long-term financial needs.

A person may stop earning a salary, begin drawing pensions or receive a lump sum.

They may also be considering downsizing, helping children buy homes or transferring business interests.

These decisions can affect the inheritance tax position.

However, retirement planning should come first.

Someone who has just retired may need to preserve capital for several decades.

In Your 70s and Beyond: Keep the Plan Practical

Later-life planning may involve reviewing existing gifts, updating wills, considering care needs and making sure executors can locate important information.

It is not necessarily too late to plan.

Some exemptions can apply immediately, and a will review may still improve the clarity of inheritance arrangements.

However, substantial gifts or complex structures should be considered carefully, particularly where they could affect financial security or create administrative difficulties.

The first step is to estimate the value of your estate.

For inheritance tax purposes, this may include your home, savings, investments, possessions and relevant business interests, less allowable liabilities.

Certain lifetime gifts and trust arrangements can also affect the calculation.

From 6 April 2027, most unused pension funds and certain pension death benefits will also be included in the inheritance tax estate.

The Main Inheritance Tax Thresholds

For the 2026/27 tax year:

These are maximum potential allowances rather than automatic tax-free amounts.

The residence nil-rate band has conditions relating to the home and eligible direct descendants.

It begins to reduce where the relevant estate exceeds £2 million.

The standard nil-rate band and residence nil-rate band are currently fixed through the 2030/31 tax year.

Does an Estate Below £325,000 Need Inheritance Tax Planning?

It may not require a detailed inheritance tax reduction strategy.

However, estate planning remains important.

A will, appropriate executors, powers of attorney and clear arrangements for beneficiaries can all be valuable even where inheritance tax is unlikely.

It is helpful to distinguish between estate planning, which concerns how your affairs and assets are managed and passed on, and inheritance tax planning, which considers the tax consequences.

The two overlap, but they are not the same.

Property can make an estate more valuable than it initially appears.

Someone may have relatively modest savings but own a home that has increased substantially in value.

For example, a homeowner with a property worth £550,000 and savings of £150,000 has assets totalling £700,000 before considering liabilities or other assets.

Whether inheritance tax is payable depends on the available allowances, beneficiaries and other circumstances.

Example 1: A Single Homeowner With a £700,000 Estate

Consider a widowed or single homeowner whose estate consists of:

Assume the estate passes to adult children.

For simplicity, assume the full individual standard nil-rate band and residence nil-rate band are available, with no transferable allowances, relevant lifetime gifts or other adjustments.

This does not mean the homeowner should immediately give away £200,000.

It means an inheritance tax review may be worthwhile.

The review could consider the will, available exemptions, future expenditure and whether any appropriate planning opportunities exist.

Married couples and civil partners can often benefit from valuable inheritance tax exemptions and transferable allowances.

Assets passing to a qualifying spouse or civil partner are generally exempt from inheritance tax.

Unused nil-rate band and residence nil-rate band allowances may also be transferred to the surviving spouse's or civil partner's estate, subject to the relevant conditions.

This can mean a qualifying couple potentially benefits from allowances totalling £1 million.

However, the full amount is not available automatically in every case.

Example 2: A Married Couple With an £850,000 Estate

Suppose a married couple own:

Assume the first spouse dies leaving everything to the survivor.

When the survivor dies, the estate passes to adult children.

If the full unused allowances are transferable and all relevant conditions are satisfied, the £850,000 estate may fall within the combined £1 million allowances.

There may therefore be no inheritance tax liability.

This illustrates why calculating the available allowances should come before considering substantial lifetime gifts.

What About Unmarried Couples?

Unmarried couples do not generally benefit from the same inheritance tax spouse exemption or transferable allowances.

They also do not automatically inherit under the intestacy rules simply because they have lived together for many years.

For unmarried homeowners, an estate planning review can therefore be particularly important.

Property ownership, wills and the financial position of the surviving partner should be examined together.

A review is often more useful when prompted by a meaningful change than by reaching a particular age.

1. Buying or Inheriting a Valuable Property

A property purchase or inheritance can substantially increase the value of an estate.

It may also affect who owns the property and how it will pass on death.

Where a home is intended to pass to children or grandchildren, the residence nil-rate band may become relevant.

2. Getting Married or Entering a Civil Partnership

Marriage or civil partnership can change the inheritance tax position.

The spouse exemption and transferable allowances may become relevant.

In England and Wales, marriage or civil partnership can also revoke an existing will unless it was made in contemplation of that marriage or civil partnership.

A review should therefore address the will as well as the tax position.

3. Divorce, Separation or a New Relationship

Relationship changes can affect intended beneficiaries, property ownership and inheritance arrangements.

A will made before divorce may no longer produce the intended result.

A new relationship can also create competing family interests, particularly where children from previous relationships are involved.

4. Receiving a Substantial Inheritance

An inheritance can increase the value of your own estate.

For example, someone may inherit £250,000 from a parent while already owning a valuable home.

The additional wealth may change their inheritance tax exposure.

It may also create an opportunity to review long-term financial objectives.

5. Selling or Growing a Business

Business owners may have substantial wealth tied up in company shares or trading assets.

Business Relief can be relevant, but eligibility depends on the business and assets.

The April 2026 reforms introduced a £2.5 million allowance for qualifying business and agricultural property eligible for 100% relief, with 50% relief generally applying above that allowance.

A business valuation or ownership change may therefore justify a specialist review.

6. Approaching or Entering Retirement

Retirement can change income, expenditure and the need to retain accessible capital.

It may also be the point at which people consider supporting children or grandchildren financially.

Any gifting strategy should be tested against long-term retirement needs.

7. A Significant Change in Tax Legislation

Inheritance tax legislation can affect decisions made years earlier.

For example, the April 2027 pension changes mean many families will need to reconsider how unused pension funds fit into their estate calculations.

A legislative change does not automatically require immediate action, but it can make a review worthwhile.

The initial process does not need to be complicated.

A sensible starting point is to gather information and identify the questions that require attention.

Step 1: Prepare an Estate Inventory

List the assets you own and their approximate values.

Include:

• Your home and other property.
• Bank and building society accounts.
• Investments and ISAs.
• Business interests.
• Valuable possessions.
• Life assurance arrangements.
• Pension schemes and potential death benefits.
• Relevant liabilities.

You should also record whether assets are owned individually or jointly.

This can affect how they pass on death and how they are valued.

Step 2: Identify Your Intended Beneficiaries

Consider who you want to benefit from your estate.

For example:

• A spouse or civil partner.
• Children.
• Grandchildren.
• A long-term unmarried partner.
• Other relatives or friends.
• Charities.

Different beneficiaries can affect the inheritance tax treatment.

The residence nil-rate band, for example, generally requires a qualifying home to pass to eligible direct descendants.

Step 3: Review Your Will

Check whether your will reflects your current wishes.

Consider whether the executors and trustees remain suitable.

If you have remarried or have children from different relationships, ensure the arrangements are appropriate.

A will can be important even where inheritance tax is unlikely.

Step 4: Estimate the Potential Inheritance Tax

Compare the estimated estate value with the available allowances.

Consider whether any exemptions or reliefs may apply.

Where the estate includes business interests, trusts or substantial lifetime gifts, a straightforward calculation may not be sufficient.

The purpose of an initial estimate is to identify whether further planning is warranted.

Step 5: Assess Your Financial Needs

Before making gifts, consider your income, expenditure and future financial requirements.

Include a margin for inflation, emergencies and potential care needs.

If you are retired, consider the possibility of living for many more years.

This step helps prevent inheritance tax planning from undermining financial independence.

Step 6: Identify Appropriate Planning Options

Depending on the circumstances, these may include reviewing wills, using available gift exemptions, considering regular gifts from surplus income or assessing whether life assurance could help with liquidity.

Trusts may be relevant where there is a genuine need for beneficiary protection or control.

However, none of these arrangements should be assumed suitable without examining the consequences.

Step 7: Keep Records and Set a Review Date

Document significant gifts, asset values and relevant decisions.

Keep details of pension schemes, insurance policies and professional advisers accessible to those who may administer your estate.

Arrange to revisit the plan when circumstances change.

There is a difference between beginning inheritance tax planning early and making large gifts early.

Planning early is generally about understanding options and preserving flexibility.

Gifting can be irreversible.

An outright gift to a child may reduce a future inheritance tax liability if the relevant conditions are met, but it also transfers ownership and control.

The child may use the funds, invest them, divorce or experience financial difficulties.

The donor may later need the money.

The Seven-Year Rule Is Not a Reason to Rush

Many outright gifts to individuals become exempt from inheritance tax if the donor survives seven years.

However, the rule does not mean that making a gift as soon as possible is always sensible.

The donor's financial position should be considered first.

Giving away a house while continuing to benefit from it can also trigger the gift with reservation of benefit rules.

For these reasons, early planning should begin with an affordability assessment rather than a transfer deadline.

No.

There is no age limit on reviewing a will, checking inheritance tax allowances or improving estate records.

Certain gift exemptions may also be relevant regardless of age.

For example, the annual gift exemption can apply to qualifying gifts without a seven-year survival requirement.

Regular gifts from genuine surplus income may also qualify for exemption where the statutory conditions are satisfied.

However, later-life planning should be particularly sensitive to the donor's health, financial needs and ability to make informed decisions.

What if Someone Has Lost Mental Capacity?

If someone no longer has capacity to make particular financial decisions, attorneys or deputies must act within their legal authority.

They cannot simply make large inheritance tax planning gifts on the person's behalf.

Restrictions apply, and court authorisation may be needed for gifts outside the permitted powers.

This is one reason to consider Lasting Powers of Attorney as part of wider estate planning before they are needed.

The relevant legal arrangements differ across the UK's nations.

There is no universal statutory review interval.

For many families, reviewing the plan every two to three years may be a useful practical starting point, with earlier reviews after major changes.

More complex estates may require more frequent attention.

The review should consider both the family's circumstances and the current legislation.

A Simple Review Schedule

These are practical suggestions, not legal deadlines.

A review does not necessarily mean changing anything.

Sometimes the correct outcome is to confirm that the existing arrangements remain suitable.

Delaying inheritance tax planning can reduce the options available later.

For example, someone who wants to make a substantial lifetime gift may prefer to consider it while they are healthy and financially secure.

Waiting until later life can make affordability and capacity more complicated.

An outdated will may also fail to reflect family changes.

Executors may struggle to identify gifts, pension schemes or other assets if records are incomplete.

However, this should not be interpreted as a reason to rush into complex arrangements.

The objective is to make informed decisions with enough time to understand their consequences.

From 6 April 2027, most unused pension funds and certain pension death benefits will be included in the inheritance tax estate.

The changes were enacted through Finance Act 2026.

This means some families whose pensions were previously expected to sit outside inheritance tax may need to revise their estate estimates.

Who Should Review Their Position?

A review may be particularly useful for people with substantial unused pension funds, valuable property or other investments.

It may also be relevant where a pension holder intends to leave pension wealth to adult children.

However, not all pension death benefits are included, and exemptions and allowances remain relevant.

It would be inappropriate to assume that everyone should withdraw pension funds before April 2027.

Withdrawals can create income tax liabilities and reduce retirement security.

Mistake 1: Assuming Your Estate Is Too Small

A valuable home can make an estate larger than expected.

The correct starting point is an estimate, not an assumption.

Mistake 2: Assuming You Must Give Assets Away

Some families already have sufficient allowances to avoid inheritance tax.

Others may benefit from relatively straightforward changes or better record-keeping.

Large gifts are not always necessary or appropriate.

Mistake 3: Focusing on Tax Without Considering the Family

An arrangement that reduces inheritance tax may still be unsuitable if it creates disputes, leaves a spouse financially insecure or prevents someone from accessing their own assets.

Estate planning should address the practical needs of the family as well as the tax calculation.

Inheritance tax planning does not need to begin with a complicated trust or an immediate transfer of property.

At Telmar Estate Planning, the starting point can be a review of the family's existing arrangements, intended beneficiaries and estate planning priorities.

This can help identify whether wills need updating, whether inheritance tax allowances deserve closer attention and whether further specialist advice may be appropriate.

Complex tax calculations, regulated investment decisions, pension withdrawal strategies and specialist trust arrangements may require suitably qualified advisers.

The objective should be to help families understand their options and make proportionate decisions at the right time.

The best time to begin inheritance tax planning is when you have enough information to make useful decisions — and before an important family or financial change leaves you with fewer options.

For some homeowners, that may be in their 40s or 50s.

For others, retirement may provide a natural opportunity to review their estate.

And for people who have never considered inheritance tax before, starting later can still be worthwhile.

The first steps are usually straightforward: value the estate, check the available allowances, review the will and consider the family's long-term financial needs.

Early planning creates time to make informed decisions.

It should not create pressure to give away assets before you are ready.
