Gifts Out of Surplus Income: The IHT Exemption

Yes — if you give money away regularly out of your surplus income, and doing so does not reduce your normal standard of living, those gifts are immediately free of inheritance tax. This is the "normal expenditure out of income" exemption, one of the most generous and underused reliefs in the inheritance tax system in England and Wales. Crucially, there is no upper limit on how much you can give this way, and qualifying gifts fall straight out of your estate without the usual seven-year survival period.

That combination — unlimited amounts and no seven-year wait — makes it a powerful tool for anyone whose income comfortably exceeds their spending. But the relief is precise, and HMRC scrutinises claims carefully, so it pays to understand exactly how it works before you rely on it.

What is the surplus income exemption?

The exemption sits in section 21 of the Inheritance Tax Act 1984. In plain English, a gift is exempt if it forms part of your normal expenditure, is made out of income, and leaves you with enough income to maintain your usual standard of living. Get all three right and the gift never enters your estate for inheritance tax purposes — even if you die shortly afterwards.

Compare that with an ordinary lifetime gift (a "potentially exempt transfer"), which only becomes fully exempt if you survive seven years. The surplus income exemption skips that risk entirely. It also sits alongside the £3,000 annual exemption and the small-gifts exemption, so you can use it in addition to those allowances rather than instead of them.

The three conditions you must meet

Every qualifying gift must satisfy all three of the following tests. They are cumulative — failing any one disqualifies the gift:

• It must be part of your normal expenditure. The gift has to be habitual or part of a settled pattern — not a one-off windfall handed on.
• It must be made out of income. The money must come from your income for the year, not from capital or savings that have become capital.
• It must leave you able to maintain your usual standard of living. After the gifts, your remaining income must still be enough to cover your normal outgoings without dipping into capital.

Each of these deserves a closer look, because the detail is where claims succeed or fail.

What counts as "income"?

Income generally means money you receive on a recurring basis: salary, self-employment profits, pensions in payment, rental income, dividends, interest, and similar. It is your income after income tax has been paid — you assess "net" income for these purposes.

What does not count is capital. Selling shares, drawing down an investment portfolio, releasing equity from your home, or spending a lump-sum inheritance are all capital, not income. A particularly common trap is the tax-free pension lump sum (the 25% pension commencement lump sum), which HMRC normally treats as capital, not income. Regular pension income you draw, by contrast, is income and can be used. Because pensions are changing for inheritance tax from April 2027, take advice before building plans around pension assets.

Income you have saved counts as capital once it has lost its character as income. HMRC accepts that income accumulated over a year or two can still be treated as income, but money sitting in a savings account for several years is usually treated as capital. The safest approach is to give from current-year income.

"Surplus" and the standard-of-living test

The word "surplus" is doing a lot of work. The exemption only covers gifts you can afford to make out of income while still living as you normally do. If giving the money away forces you to eat into savings to pay your everyday bills, the gift does not qualify.

In practice you look at your income for the year, deduct your normal living expenditure — mortgage or rent, council tax, food, holidays, the lifestyle you are used to — and the surplus that remains is what you can give. There is no fixed percentage; it is judged on your actual circumstances. Someone with a large pension and modest tastes may have a substantial surplus, while a higher earner with expensive commitments may have little.

The test is applied over time, not gift by gift. HMRC and the courts look at the overall pattern, typically year on year. An occasional year where income dips need not destroy the exemption if the broader picture shows gifts genuinely came from surplus income.

The "normal" (regular) requirement

"Normal" means part of a settled, habitual pattern of giving. The classic examples are paying a grandchild's school fees each term, funding a regular contribution to a child's pension or ISA, or making a fixed monthly gift to a family member. Regularity is the key signal.

You do not always need a long history before the first gift, though. HMRC accepts that a pattern can be established by a clearly stated intention to make regular gifts — for example, a signed letter saying you intend to give £500 a month from your income indefinitely. If you then die after only a few payments, your executors can point to that documented intention to show the gifts were "normal". Setting out your intention in writing at the outset is therefore one of the most valuable things you can do.

Why this exemption is so valuable

For estates likely to face the 40% inheritance tax charge above the nil-rate band, regular giving from income is among the cleanest ways to reduce the eventual bill. There is no cap, no seven-year clock, and no need to create a trust or part with assets you may later need.

It is especially effective for people with strong pension income, buy-to-let rents, or substantial dividends who do not spend everything they receive. Used consistently over a decade or two, it can move very large sums out of an estate entirely tax-free.

Keeping records: form IHT403

The exemption is claimed by your executors after your death, using form IHT403. That form asks for a year-by-year breakdown of your income, your expenditure, and the gifts you made, to demonstrate that gifts came from surplus income and left your standard of living intact.

Because your executors will be reconstructing this from your paperwork, the single most helpful thing you can do is keep contemporaneous records yourself. A simple annual schedule — income in, normal outgoings, gifts made — mirroring the IHT403 layout, supported by bank statements and an initial statement of intent, makes the claim straightforward. Without records, executors often cannot prove the gifts qualified, and the relief is lost.

Common mistakes and pitfalls

• Giving from capital and calling it income. Selling investments or using savings to fund "regular" gifts does not qualify, however consistent the pattern.
• One-off lump sums. A single large gift, with no pattern or stated intention, will struggle to meet the "normal" test and is better treated as a potentially exempt transfer.
• Reducing your own standard of living. If the gifts mean you have to draw on capital to live, they fall outside the exemption.
• No paper trail. The exemption is real, but unprovable claims fail. Document income, expenditure, gifts and intention.
• Confusing it with other reliefs. This exemption is separate from the £3,000 annual exemption and the small-gifts allowance — you can use them together.

When to get professional advice

The principles are simple, but the application can be genuinely complex — particularly where income fluctuates, where capital and income are mixed, where gifts run through trusts, or where pension drawdown is involved. The interaction with the changing pension rules and with trust planning means professional advice is strongly recommended before you commit to a long-term gifting plan. A qualified estate planner can design a documented, defensible giving strategy and set up the records your executors will need. If you are also weighing up trusts, our guide on putting life insurance in trust shows how regular premium gifts and this exemption often work hand in hand.

Used properly and documented well, gifts out of surplus income remain one of the most efficient and flexible inheritance tax planning tools available in England and Wales.
