Normal Expenditure Out of Income Exemption: Conditions and Claims

The normal expenditure out of income exemption lets you give away money free of inheritance tax, with no upper limit and no seven-year survival requirement, as long as the gifts form part of a regular pattern paid from your surplus after-tax income and leave you enough to live on. It sits in Section 21 of the Inheritance Tax Act 1984 and is one of the most generous reliefs in the IHT system, but the test is applied after you die, and your executors carry the burden of proving it. With the nil-rate band frozen at £325,000 until at least 2030–31, the exemption rewards people whose income comfortably exceeds their spending and who are willing to keep the records to prove it.¹

The Three Conditions a Gift Must Meet

Section 21 sets out three requirements, and all three have to be satisfied for the exemption to apply:²

The gift must form part of the donor’s normal expenditure, meaning it fits into a settled pattern of giving rather than being a one-off.
Taking one year with another, the gift must be made out of income rather than capital.
After the gift, and after all other gifts claimed under this exemption, the donor must still have enough income left to maintain their usual standard of living.

Your executors will need to demonstrate each of these to HMRC after your death. That is why the exemption depends less on doing anything clever with the money and more on documenting what you did, why you did it, and where the money came from.

What Counts as Income

The income and capital distinction is where most claims come unstuck. For this exemption, income means income in the ordinary accounting sense, after income tax has been paid. That will not always line up with how income is defined for income tax purposes.³

Sources that clearly count as income include salary, business profits, pensions, dividends, savings interest, rental income, and the income element of annuity payments. What these have in common is that they represent new money arriving in the donor’s finances during the tax year.

Selling a property, cashing in an investment, or drawing down the principal from a savings account is capital, not income. A frequent trap involves insurance bond withdrawals: the 5% annual withdrawal often treated as tax-deferred for income tax purposes is actually a return of capital, and it cannot be used to fund a claim under this exemption.³

When Income Turns Into Capital

You do not have to gift income the moment it lands in your account. HMRC’s working view is that income which sits ungifted for more than about two years generally becomes capital, unless you can explain the delay. That two-year rule has no basis in the statute. In McDowall, the Special Commissioners accepted that income accumulated over three years still qualified because the donor had a clear intention to gift it. If you plan to save up income before giving it away, write down that plan at the start.³

What “Normal” Means

The leading case on this is Bennett v IRC. The court defined normal expenditure as spending that accords with a settled pattern adopted by the donor. You can establish that pattern either by actually making regular payments over time, or by assuming a firm commitment to make regular payments and then following through.²

A few useful points come out of Bennett:

There is no fixed minimum period. What matters is that the pattern is established on the evidence as a whole.
The amounts do not have to be identical each time. A formula works too, such as “all surplus income above a set amount” or “enough to cover school fees.”
The recipients can change, provided the gifts go to the same class of beneficiary, such as children or grandchildren.
Wanting to reduce a future IHT bill does not disqualify the gifts. The court confirmed the donor’s motivation is irrelevant.

Can a One-Off Gift Qualify?

Yes, but only where there is strong evidence you meant to keep giving. A standing order set up to run indefinitely, a signed letter of intent, or written instructions to a financial adviser all help. HMRC’s own guidance warns against accepting bare assertions that income was being accumulated with the intention of gifting when nothing supports the claim.⁴ If the donor dies soon after a first gift with no paperwork behind it, the executors will struggle.

Gifts That Typically Qualify

The exemption is flexible. HMRC and the case law recognise a wide range of regular payments:⁵

Regular monthly or annual transfers to adult children or grandchildren for living costs, rent, or general support.
Termly school or university fees, even though the amounts change as fees rise.
Regular contributions to a savings account for a child under 18.
Premiums on a life insurance policy held in trust, subject to the anti-avoidance point below.
Ongoing financial help for an elderly parent or other relative.
Regular payments into a discretionary trust for a class of beneficiaries.

Occasional cheques sent when you happen to feel generous, with no underlying commitment, are the opposite of what the exemption rewards. They will usually be treated as potentially exempt transfers subject to the seven-year rule.

Working Out Your Surplus Income

The maths is simple in principle. Start with your total income from all sources. Subtract income tax. Subtract your normal living expenses. What remains is your surplus, and if your gifts in that year fall within it, condition three is satisfied.

The statute’s phrase “taking one year with another” gives some room to manoeuvre. A shortfall in a single year does not automatically break the exemption if there is an overall surplus across the period when gifts were made. That helps donors whose income moves around, such as those with variable dividends or rental voids.

Living expenses for this purpose cover mortgage or rent, insurance, council tax, household bills, food, travel, holidays, entertainment, and care home fees where relevant. Capital spending, such as a house extension or a new car, does not go into this calculation. The question HMRC will ask is whether you had to dip into savings or sell assets to fund your usual lifestyle after making the gifts. If the answer is yes, the exemption fails for that year.²

How This Sits Alongside Other Gift Exemptions

Several other IHT gift exemptions run in parallel, and you can combine them for the same recipient in most cases:

The annual exemption of £3,000 per tax year applies whether the money comes from income or capital. An unused amount can be carried forward one year only.
The small gifts allowance lets you give up to £250 to as many different people as you like in a tax year, but you cannot combine it with any other exemption for the same recipient.
Wedding and civil partnership gifts of up to £5,000 from a parent, £2,500 from a grandparent, or £1,000 from anyone else can be combined with the annual exemption and the normal expenditure exemption for the same person.⁵

Because Section 21 has no monetary cap, it becomes the workhorse once the fixed allowances are used up. Someone with £80,000 of surplus income each year can give the full amount away every year, provided the three conditions hold. No other exemption offers that scale.³

Records to Keep While You Are Alive

This is where claims are won or lost, and it happens long before any form gets filed. Keep a year-by-year log covering three things: your total after-tax income, your total living expenses, and the gifts you have made. Executors who inherit a shoebox of statements and no organised records face a genuinely difficult reconstruction exercise.

The categories mirror what Schedule IHT403 asks for. On the income side, track salary, pensions, savings interest, dividends, rental income, annuity income, and any other regular receipts, less income tax paid. On the expenditure side, record mortgage or rent, insurance, household bills, council tax, travel, entertainment, holidays, care home fees, and other routine costs.⁶

A few practical habits make the difference:

Write a dated note explaining what you intend to give, to whom, how often, and from what source. It does not need to be a legal document.
Use standing orders or direct debits where you can. Automated payments create an automatic paper trail.
Update a simple spreadsheet each tax year with income, expenses, surplus, and gifts made. It directly mirrors the IHT403 layout.
Keep gifts within your surplus. If income drops in a given year, reduce the gifts rather than dipping into savings. A year funded from capital poisons the claim for that year and can cast doubt on the whole pattern.
Tell your executors about the plan, where the records are, and which exemption you are relying on. An executor who does not know may not claim it at all.

How the Claim Is Made After Death

The formal claim happens through Schedule IHT403, submitted alongside Form IHT400, the main Inheritance Tax account.⁷ IHT403 asks executors to set out a year-by-year income and expenditure summary for the tax years in which gifts were made, together with the date, recipient, and amount of each gift. Page 8 is the key section for a normal expenditure claim: it lists each income source, deducts tax, itemises living expenses, and compares gifts against the resulting surplus.⁶

Not every estate has to go through this process. Where an estate qualifies as excepted because its gross value falls within the nil-rate band, or double the nil-rate band if a transferred allowance applies, no IHT400 is needed and IHT403 is not filed. The exemption still applies in principle, but there is nothing to claim because no tax is due.

Where the IHT400 is required, HMRC may follow up asking for bank statements, dividend vouchers, or pension statements to verify the split between income and capital. Executors who can produce a clear log, along with any letters of intent, tend to see the claim accepted without a long back-and-forth.

The Life Insurance Anti-Avoidance Rule

Section 21 contains a targeted anti-avoidance rule aimed at schemes that pair a purchased life annuity with a life insurance policy. If you buy an annuity on your own life and use the annuity income to pay premiums on a life policy, those premiums cannot qualify as normal expenditure unless you can show the two transactions were not associated operations.²

The rule also stops the capital element of a purchased life annuity (the part exempt from income tax) being treated as income for this exemption. It is not. The point is to prevent a donor turning capital into what looks like income by buying an annuity and then gifting the payments. Ordinary life insurance premiums paid out of genuine surplus income, such as salary or pension, are not caught.
