A quiet Inheritance Tax strategy that more families should understand

One of the most powerful inheritance tax exemptions in the UK tax code is also one of the least understood.

It’s called “Normal Expenditure Out of Income.”

Under Section 21 of the Inheritance Tax Act 1984, it allows someone to make unlimited gifts during their lifetime, without triggering inheritance tax — even if they die within seven years.

That’s unusual, because most lifetime gifts fall under the seven-year rule for Potentially Exempt Transfers (PETs).

But this exemption works differently.

Used properly, it can become an important planning tool for families looking to reduce the size of their estate over time, particularly as attention starts to turn to the possible inclusion of pensions in the inheritance tax net from 2027.

The Three Conditions

For the exemption to apply, three key conditions must be met.

The gift must:

1. Form part of the donor’s normal expenditure

2.  Be made out of income

3. Leave the donor with enough income to maintain their normal standard of living

On paper, this sounds straightforward.

In practice, the complexity usually comes down to one question:

Was the gift really made from income — or from capital?

What Counts As “Income”?

Interestingly, the legislation doesn’t define income.

However, in most cases it includes:

1. Salary or employment income

2. Pension income (including drawdown income)

3. Dividends

4. Interest

5. Rental income

6. Annuity payments

But what really matters is the economic substance of the transaction.

If a gift is ultimately funded from capital rather than income, the exemption will usually fail.

The Key Concept: Surplus Income

In practical planning terms, advisers often calculate “surplus income.”

The idea is simple:

Net Income – Normal Living Costs = Surplus Income

That surplus income can then potentially be gifted.

There are two nuances here that are often missed:

1️⃣ Surplus income can accumulate before being gifted

2️⃣ But it must still be identifiable as income rather than capital

Once it disappears into general savings or investment accounts, the evidential position can become much harder to defend.

Where Many Claims Go Wrong

In reality, many claims for this exemption fail because the gifts were actually funded from capital.

Common examples include:

• Withdrawals from investment portfolios

• ISA withdrawals

• Historic savings

• Proceeds from selling assets

• Loan drawdowns

Even pension commencement lump sums will usually be treated as capital rather than income.

This is where things become particularly tricky.

Many people believe they are giving away “income,” but when the numbers are examined later, the gifts were actually made from capital withdrawals.

The Evidence Problem

Another issue arises years later when executors are asked to prove the exemption.

HMRC will usually expect evidence showing:

• A pattern of gifting (or intention to establish one)

• A clear income and expenditure schedule

• Confirmation that the donor’s standard of living was unaffected

If that documentation doesn’t exist, what everyone assumed were “gifts from income” can quickly become Potentially Exempt Transfers, bringing the seven-year rule back into play.

Why This May Become More Important

The conversation around UK inheritance tax is evolving.

With proposals suggesting that pension funds could fall within the inheritance tax framework from 2027, many families are starting to rethink how wealth flows through generations.

Strategies that rely solely on leaving assets untouched until death may come under greater scrutiny.

In contrast, structured lifetime gifting from surplus income can be a very effective way to reduce the taxable estate gradually — while still maintaining financial security.

The Practical Lesson

This exemption works best when it is planned and documented each year.

That means:

• Tracking income

• Tracking expenditure

• Demonstrating genuine surplus income

• Maintaining a clear pattern of gifting

Without that structure, what was intended as a tax-efficient gift can easily become something else entirely.

Final Thought

Inheritance tax planning is rarely about one dramatic decision.

More often, it’s about consistent, well-structured actions taken over time.

“Normal expenditure out of income” is one of those quiet strategies that can make a meaningful difference when applied correctly.

If you’re a UK national living abroad — or considering a move to somewhere like Portugal — the interaction between UK inheritance tax rules, pensions, and cross-border planning deserves careful thought.
