Most people know that gifts can reduce an Inheritance Tax bill if you survive seven years. Far fewer know about an exemption that works immediately, with no waiting period at all, and no cap on the amount involved. It is called normal expenditure out of income, and it is one of the most underused reliefs in Inheritance Tax planning.
While everyone has heard of the £3,000 annual gift exemption, this relief can, for the right family, remove far larger sums from an estate every single year, with the gifts falling outside your estate from the moment you make them. The catch is that HM Revenue and Customs applies three tests, and the record-keeping has to be right. Get it wrong, and the exemption can unravel entirely.
What the exemption actually says
Section 21 of the Inheritance Tax Act 1984 exempts gifts that are: made as part of your normal expenditure, made out of income, and that leave you with enough income to maintain your usual standard of living. If a gift satisfies all three, it is exempt immediately. There is no seven-year survival period to worry about, and in principle no upper limit on the amount, provided the three tests are genuinely met.
This is very different from the £3,000 annual exemption, which is a fixed allowance regardless of your income or spending patterns. Normal expenditure out of income is really about your financial behaviour over time: are you giving away money you did not need, in a way that has become part of your normal pattern of living?
The three tests, in plain terms
1. It must be made out of income, not capital. HMRC looks at your income for the tax year in question, from sources such as pensions, salary, dividends, rental income and interest. Selling an asset or drawing down savings to fund a gift does not count. If you dip into capital to make ends meet after gifting, that undermines the claim.
2. It must be regular or habitual. A single one-off gift, however well-intentioned, is unlikely to qualify. HMRC wants to see a pattern: gifts made annually, monthly, or on a recognisable and repeated basis. This does not mean the amount has to be identical every time, but there should be a clear and demonstrable regularity, such as paying school fees each term or a fixed sum to each grandchild every year. Setting up a standing order is often the clearest way to establish this pattern from the outset, though a documented intention to make regular gifts, followed through consistently, can also succeed even without a formal instrument.
3. It must leave you able to maintain your normal standard of living. This is the test that catches people out most often. HMRC is not asking whether you could survive on less. It is asking whether, after making the gift, you were still able to live in the manner you were accustomed to, without needing to fall back on capital. If your income is £60,000 and your normal outgoings are £58,000, you do not have £2,000 of genuine surplus to give away every year without care, particularly once inflation and one-off costs are considered.
Worked examples
Funding grandchildren’s school fees. Grandparents with a comfortable pension income sometimes agree to pay a grandchild’s school fees directly to the school, each term, for the duration of their education. Provided this is paid from income, forms a regular commitment, and does not compromise the grandparents’ own standard of living, the whole amount can be exempt from Inheritance Tax immediately, term after term, for years. Over the course of a secondary education this can easily remove well over £100,000 from an estate, entirely outside the seven-year rule.
Paying life assurance premiums for others. A common and often overlooked example is paying the premiums on a life assurance policy written in trust for children or grandchildren, or even paying premiums on a policy designed to cover a future Inheritance Tax bill. Because premiums are typically paid annually or monthly from income, this fits the “regular” test naturally, and can be one of the cleanest ways to use this exemption, since the payment pattern is fixed by the policy itself.
Supporting adult children with regular sums. Some parents choose to give an adult child a set monthly amount, perhaps to help with a mortgage or childcare costs, rather than one large gift. If this is affordable from income and continues consistently, it can be treated the same way as the school fees example.
The record-keeping HMRC expects
This exemption lives or dies on evidence, and that evidence is usually assessed only after death, when it is too late to fix any gaps. Executors must complete form IHT403 as part of the estate’s Inheritance Tax return, and HMRC will expect to see, ideally going back several years:
- A clear record of the gifts made: who received them, when, and how much
- Evidence the payments came from income (bank statements showing income received and gifts paid out separately from capital accounts)
- A summary of total income against total expenditure for each relevant tax year, showing a genuine surplus after the gifts
- Some evidence of the regular pattern, whether a standing order, a signed letter of intent, or simply a consistent history of gifts
The single most practical thing anyone relying on this exemption can do is keep a simple annual log: income received, normal living costs, gifts made, and the resulting surplus or shortfall. Many families never do this while they are alive, which leaves their executors trying to reconstruct years of financial history from old bank statements, often without success. A gift that would have qualified perfectly well can end up taxed simply because nobody kept the paperwork.
Where people get it wrong
The most common mistake is treating this as a loophole for large, irregular gifts. A single payment of £50,000 towards a house deposit, made once, does not qualify as normal expenditure, however much surplus income you happened to have that year. It may still be a Potentially Exempt Transfer, subject to the usual seven-year rule, but it is not exempt immediately under this relief.
The second common mistake is drawing on capital, or on income that has already been saved from a previous year, and describing it as income for the current year. HMRC’s view of “income” is broadly the tax year’s income for tax purposes, not accumulated savings sitting in a current account, even if that money originated from income some years earlier.
The third mistake is failing to review the arrangement as circumstances change. If your income falls, perhaps on retirement, or your living costs rise, continuing an established pattern of gifting without adjusting it can start to eat into capital, which then fails the “standard of living” test for those later gifts even though earlier ones were sound.
Why this matters now
With the nil-rate band frozen at £325,000 until 2030, the residence nil-rate band tapering away above a £2 million estate, and more assets than ever being drawn into the Inheritance Tax net, exemptions that work immediately and without limit deserve far more attention than they usually receive. For families with a genuine surplus income each year, normal expenditure out of income can, over a decade or two, remove a meaningful sum from an estate that would otherwise be taxed at 40 per cent.
The relief rewards discipline rather than cleverness. It suits people who are already inclined to help family members regularly, and who are willing to keep the records that prove it. Done properly, with clear documentation from the outset, it is one of the most valuable and least contested reliefs available. Done casually, without evidence, it is one of the most commonly disallowed.
If you think you may have surplus income you could be gifting more tax-efficiently, or if you are already making regular gifts but are not confident your records would satisfy HMRC, it is worth reviewing your position properly. A Legacy Protection Assessment looks at your whole estate, including how gifts fit alongside your Will and other planning, so nothing is left to chance.
How this fits with your wider estate planning
Normal expenditure out of income is not a substitute for a well-drafted Will, nor for the other Inheritance Tax reliefs available to you, such as Business Relief for qualifying business assets or the residence nil-rate band on a family home. It works alongside them. For a couple with a combined nil-rate band and residence nil-rate band of up to £1 million, and a genuine surplus income each year, a disciplined pattern of gifting can meaningfully reduce the value of the estate that ever needs those allowances in the first place.
It is also worth remembering that this exemption sits apart from Potentially Exempt Transfers. A one-off gift that does not qualify as normal expenditure is not lost entirely; it simply falls back into the ordinary seven-year rule, with tapering relief if you survive at least three years. The two regimes can and often do operate side by side within the same family: an annual pattern of income gifts for the exempt element, and occasional larger capital gifts accepted as Potentially Exempt Transfers for anything beyond that.
