Normal Expenditure Out of Income IHT Exemption: Section 21 IHTA 1984 — The Most Powerful Unlimited IHT Gift Exemption
Gifts made regularly from surplus income are entirely exempt from IHT under s21 IHTA 1984 — no annual cap, no 7-year wait. A retired person with a pension of £80,000 and modest expenses could give £30,000+ per year to family completely free of IHT, indefinitely. The key: three conditions, meticulous records, and starting early.
The Three Qualifying Conditions
Condition 1: Part of a normal pattern of expenditure
The gift must be part of the donor's normal expenditure — a pattern of giving that has become established or is intended to become established. 'Normal' means habitual: the donor must be in the practice of making gifts of that character, or the gift must form part of an intended programme of regular giving. A single one-off payment does not qualify (unless it is the first of a series, in which case the executors must show the intended pattern was established at the time of the gift). The pattern can be established over a relatively short period — two or three years of regular annual gifts is typically sufficient. The gifts do not have to be for the same amount each year — graduated or escalating giving programmes can qualify. They do not have to go to the same recipients each year — regular gifts to different children, grandchildren, or charities in varying amounts can all qualify.
Condition 2: Made out of income (not capital)
The gift must be made out of income — not out of capital. 'Income' for s21 purposes is the donor's after-tax income in the relevant period: employment income, pension income, interest, dividends, rental income, trust income, etc. Capital — including the proceeds of selling investments, inherited lump sums, or savings built up from past income — does not count. Where a donor has a complex income profile (pension, investments, property portfolio), HMRC will analyse the sources and check that the gifts were funded from income items. If a donor draws down savings or sells investments to fund gifts, those gifts are likely capital gifts (PETs), not income gifts (s21 exempt). The distinction between income and capital is fact-specific — detailed financial records of income and expenditure are essential.
Condition 3: No material diminution in standard of living
The gifts must be made from income that the donor can afford to give away without affecting their standard of living. This is an objective test: the donor must have sufficient income, after meeting all usual outgoings (household expenses, holidays, maintenance, subscriptions, personal spending), to make the gifts. Where a donor is drawing on capital to maintain their lifestyle (because income falls short of expenditure), there is no 'surplus' income and the s21 exemption does not apply — the gifts are out of capital. HMRC will calculate the donor's total income, subtract all expenditure (including the gifts themselves), and check whether a positive surplus remains. If the surplus is only achieved by including the gifts in the income column (i.e. the gifts are made out of income that would otherwise have been spent), the condition is met. If the surplus is negative or very marginal, HMRC may challenge the claim.
Practical Examples
Pension income gifts
A retired person receives a pension of £80,000 per year and has annual living expenses of £45,000. They give £25,000 per year to their children and grandchildren (in a combination of £3,000 annual exemption gifts and larger s21 gifts). The £25,000 annual giving represents surplus income — after meeting all outgoings, £10,000 remains. All three s21 conditions can be met if the pattern is established. Over 10 years, this could shelter £250,000 from IHT with no 7-year waiting period and no annual limit beyond what income supports.
Investment income funding gifts
A wealthy person has a portfolio generating £60,000 per year in dividends and interest. They live on £30,000 per year and give £25,000 per year to a family trust or directly to children. The gifts are funded from income (dividends, interest — not capital), form a regular annual pattern, and do not affect the donor's standard of living. S21 can apply. If the gifts are to a discretionary trust, the trust can invest and accumulate — passing on to grandchildren effectively free of IHT.
Rental income funding school fees
A landlord with rental income of £40,000 per year pays private school fees of £20,000 per year for their grandchildren. The payments are made directly to the school. They form a regular annual pattern (each year of school), are made from income (rental receipts), and the landlord's living standards are not affected. S21 can apply — making the school fee payments IHT-exempt with no limit.
Frequently Asked Questions
Is there a maximum amount that can be given under the s21 exemption?
No — the s21 normal expenditure out of income exemption has no annual limit. Provided all three qualifying conditions are met (normal pattern, income source, no standard of living diminution), gifts of any size qualify. In practice, the limit is set by the donor's surplus income — you can only give what you can afford from income without affecting your lifestyle. A person with very high income and modest personal expenditure can legitimately give very large sums annually under s21, entirely free of IHT and with no 7-year waiting period.
Do I need to keep records to claim the s21 exemption?
Yes — HMRC requires comprehensive documentary evidence to support a s21 claim after death. The executors must complete HMRC Form IHT403 (Gifts and other transfers of value) and attach income and expenditure schedules for each year in which the deceased made gifts. The ideal documentation is: (1) a contemporaneous record maintained by the donor during their lifetime — a spreadsheet of annual income, expenditure, and gifts; (2) bank statements showing the gifts made; (3) confirmation of income sources (pension statements, dividend vouchers, rental income records); and (4) evidence of annual outgoings (utility bills, direct debits, receipts). Donors should prepare and maintain IHT403-format schedules from the first year of the giving programme. Starting or maintaining these records retrospectively from estate records is much harder.
Can gifts to a trust qualify for the s21 exemption?
Yes — provided all three s21 conditions are met, gifts to a discretionary trust or other trust can qualify as normal expenditure out of income. Where a donor makes regular annual contributions to a discretionary family trust (e.g. £20,000 per year, funded from pension income), those contributions are s21 exempt — they are not CLTs for IHT, they do not use the NRB, and there is no 7-year clock. The trust can then invest and accumulate. Exit charges apply when the trust distributes (as a relevant property trust), but the trust only accumulates IHT charges on trust growth — not on the original contributions (which were s21 exempt).
What is HMRC Form IHT403 and when must it be filed?
HMRC Form IHT403 (Gifts and other transfers of value) is completed as part of the estate return (IHT400) where the deceased made gifts during their lifetime. The form records all gifts made in the 7 years before death (for PETs and CLTs) and, importantly, the income and expenditure analysis that supports a s21 claim for gifts out of normal income. Executors complete a year-by-year schedule of the deceased's income and expenditure, with the gifts shown as expenditure items, to demonstrate the three s21 conditions. If no records were maintained during the deceased's lifetime, the executors must reconstruct the income and expenditure history from bank statements, tax returns, and other documents — which is time-consuming and may be incomplete.
Can the s21 exemption be used alongside other IHT exemptions?
Yes — the s21 exemption applies in addition to (and independently of) other IHT exemptions. The most common combination: (1) annual exemption (s19: £3,000 per year) — used first against any capital gifts in the year; (2) small gifts exemption (s20: £250 per person per year) — covers small birthday and Christmas gifts; (3) s21 normal expenditure — covers larger regular income gifts. A donor can use all three in the same tax year: e.g. give £3,000 using the annual exemption (capital), give £250 each to 10 grandchildren using the small gifts exemption (capital), and give £30,000 from pension surplus to their children (s21). The NRB is not consumed by s21 gifts — they are fully exempt.
Does the s21 exemption apply in the year of death?
Yes — gifts made in the tax year of death can qualify under s21, provided all three conditions are met. The 'income' for the year of death is the pro-rated income for the period from 6 April to the date of death, and the expenditure and gift pattern for that partial year is analysed accordingly. Where a donor has a well-established giving pattern (e.g. paying school fees in September each year) and dies before the annual payment, HMRC may consider whether the gift would have been made and whether the partial year income supports it. Executors should check whether any gifts made in the year of death qualify under s21 — these would reduce the taxable estate.
