Normal Expenditure Out of Income IHT UK (2026): IHTA 1984 s.21, Three-Part Test, and HMRC Form IHT403

The normal expenditure out of income exemption (IHTA 1984 s.21) is one of the most valuable and underused IHT exemptions in English law. Its key features make it uniquely powerful: (1) IMMEDIATELY EXEMPT — NO 7-YEAR RULE: unlike potentially exempt transfers (PETs) which require the donor to survive 7 years, gifts that qualify under s.21 are IMMEDIATELY exempt from IHT. Even if the donor dies the day after making the gift, it is outside the estate; (2) NO MONETARY LIMIT: unlike the £3,000 annual exemption (IHTA 1984 s.19) or the £250 small gifts exemption (s.20), the normal expenditure exemption has NO UPPER LIMIT. A person with £200,000 of surplus income per year can give all of it away free of IHT; (3) WHAT IT IS IN PRACTICE: it is an exemption for regular gifts made from surplus income — income that the donor does not need to maintain their normal standard of living. The classic examples are: monthly cash transfers to children; payment of a child's rent or mortgage; regular school fees for grandchildren; payment of a life insurance policy premium for a child; regular gifts to support a dependent relative; (4) THE POLICY RATIONALE: Parliament intended that gifts from income (as opposed to capital) should be immediately exempt because they do not reduce the donor's capital estate. A gift from income is simply not spending the income — the estate would never have grown by that amount in any case; (5) COMPARISON WITH PETs: PETs (potentially exempt transfers) require survival for 7 years and taper only reduces the IHT (not eliminate it) for years 3–7. A regular gift programme using s.21 eliminates IHT entirely without any waiting period. For high-income individuals, s.21 is far more powerful than relying on PETs.

IHTA 1984 s.21(1) sets out three cumulative conditions. ALL THREE must be satisfied for the exemption to apply: (1) PART OF NORMAL EXPENDITURE (s.21(1)(a)): the gift must be 'part of the normal expenditure of the transferor'. 'Normal' means: HABITUAL — part of an established pattern of giving; not a one-off gift; the donor must have a settled intention to make regular gifts (or a course of dealing that has already established a pattern). KEY CASE — BENNETT v IRC [1995] STC 54: the High Court held that 'normal' does not require a long history — even a SHORT PERIOD of regular gifts can establish normality if there is a clear intention to continue. A single gift with a demonstrated intent to make it regularly can qualify from the outset. A gift can be 'normal' even if it was the FIRST in a series, provided there was a formed intention to make regular gifts; (2) MADE OUT OF INCOME (s.21(1)(b)): the gift must be made from INCOME, not capital: (a) INCOME for this purpose means the donor's income from all sources in the relevant tax year: (i) Employment income; (ii) Pension income (state pension; private pensions; annuities — all qualify); (iii) Rental income; (iv) Dividend income; (v) Interest income; (vi) Trust income (where the donor has an interest in possession); (b) CAPITAL receipts do NOT count as income for s.21 purposes — a one-off capital receipt (sale of shares; inheritance received; property sale proceeds) cannot be used to fund a 'normal expenditure out of income' gift; (3) DOES NOT REDUCE STANDARD OF LIVING (s.21(1)(c)): after making the gift, the donor must be able to maintain their USUAL STANDARD OF LIVING from the income that remains. The donor's standard of living should be assessed by reference to their actual lifestyle — not a minimum standard. If the donor gives away income that leaves them unable to pay their normal bills, household expenses, or maintain their accustomed lifestyle, the exemption fails; (4) HMRC'S APPROACH — FORM IHT403: when an estate is administered after death, the executors must account for all gifts made in the 7 years before death. Gifts claimed as normal expenditure out of income must be declared on IHT400 Schedule IHT403 ('Gifts and other transfers of value'). HMRC requires a YEAR-BY-YEAR breakdown of: (a) income from all sources; (b) expenditure (including the gifts); (c) the surplus income available; (d) demonstrating that the gift came from that surplus.

The biggest practical problem with the s.21 exemption is DOCUMENTATION. HMRC requires proof that the three conditions were met — and the donor is dead when the claim is made, so they cannot be questioned: (1) KEEP A CONTEMPORANEOUS GIFT RECORD: the donor (or their financial adviser) should maintain a WRITTEN RECORD of each gift year by year, recording: (a) The date and amount of each gift; (b) The recipient; (c) The source of funds (which income stream); (d) The donor's income for the year (evidence: bank statements; tax returns; pension statements); (e) The donor's expenditure for the year (evidence: bank statements); (f) The surplus (income minus expenditure — showing the gift came from surplus); (2) THE IDEAL FORMAT — YEAR-BY-YEAR TABLE: a simple table showing: Tax year | Income | Expenditure | Surplus available | Gift made | s.21 Exemption claimed. This can be completed annually and should be kept with the will and estate papers; (3) A STANDING ORDER HELPS: gifting by STANDING ORDER (rather than ad hoc bank transfers) provides bank statement evidence of regularity — the pattern is clearly visible from the bank records; (4) STATEMENT OF INTENT: when starting a gift programme, consider writing a SHORT LETTER to yourself (or to your solicitor for safekeeping) recording: 'I intend to make regular gifts of £X per month to [name] from my surplus income, as I believe this will qualify for the s.21 normal expenditure out of income exemption'. This establishes intent from the outset (for Bennett v IRC purposes); (5) WHAT HAPPENS ON DEATH — FORM IHT403: the executor must complete HMRC Form IHT403 for all gifts in the 7 years before death. For s.21 gifts, they must provide a year-by-year breakdown of income and expenditure. Without contemporaneous records, the executor faces the difficulty of reconstructing years of income/expenditure data — often from incomplete bank statements; (6) HMRC'S SCRUTINY: HMRC scrutinises s.21 claims carefully, especially for: large amounts; gifts that started shortly before death; situations where the donor's health was deteriorating before the gift programme began; cases where other income fluctuated significantly year-to-year. Good documentation is the only reliable protection.

The definition of 'income' for s.21 purposes is broad. Most income streams qualify: (1) PENSION INCOME — YES (and very commonly used): (a) State pension (New State Pension £221.20/week = £11,502.40/year from April 2026): qualifies as income; (b) Defined benefit (final salary) pension: qualifies; (c) Defined contribution pension (drawdown; annuity; income paid out of a fund): qualifies; (d) Drawdown pension: HERE IS THE KEY POINT — if the pensioner is taking income EXCEEDING what they need for living expenses, the excess qualifies for s.21. Many retirees have more pension income than they spend; (e) UNCRYSTALLISED PENSION: money still IN the pension pot is not income — only the amount actually drawn out as income counts; (2) RENTAL INCOME — YES: rental income from investment property qualifies as income for s.21 purposes. Net rental income (after mortgage interest; maintenance costs; letting agent fees) is the relevant figure; (3) DIVIDENDS — YES: dividend income from shares (whether listed or private company) qualifies; (4) INTEREST — YES: interest from savings accounts; bonds; gilts qualifies; (5) EMPLOYMENT INCOME — YES: salary; bonuses; director's remuneration; all qualify; (6) TRUST INCOME (IIP) — YES: income from an interest in possession trust to which the donor is entitled qualifies; (7) INHERITANCE/CAPITAL RECEIPTS — NO: a one-off inheritance, sale of property, or maturing ISA is CAPITAL, not income — cannot be used for s.21 gifts. However, if a capital sum is invested and produces INCOME (interest; dividends; rent), that income qualifies; (8) IHT ON PENSION DEATH BENEFITS (FROM 2027 — NOTE): the Finance Act 2024 proposed to include undrawn pension funds in the estate for IHT from 2027. This does NOT affect s.21 — income drawn from pensions and given away as normal expenditure is still exempt under s.21; it affects the RESIDUAL FUND not yet drawn down.

The s.21 exemption is powerful but frequently fails in practice due to common avoidable errors: (1) PITFALL — SPENDING CAPITAL, NOT INCOME: the most common failure is when the donor actually has INSUFFICIENT INCOME to make the gift and uses capital (savings; investment account withdrawals) to fund it. The gift appears regular but it is actually from capital — the exemption fails. FIX: track income vs expenditure carefully each year. If income is insufficient, accept that the s.21 exemption is not available and rely on the 7-year PET rules instead; (2) PITFALL — IRREGULAR GIFTS (PATTERN NOT ESTABLISHED): a gift programme that stops and starts (giving £20,000 one year; nothing the next; £15,000 the year after) lacks the 'normal' pattern that HMRC requires. FIX: use a standing order; set a consistent amount; keep it regular even if relatively small; (3) PITFALL — FAILING TO DOCUMENT: executors regularly claim s.21 exemption with no contemporaneous records — relying on bank statements alone, without the income/expenditure breakdown. HMRC rejects these claims. FIX: keep a year-by-year table from the outset; review it annually; store with the will; (4) PITFALL — GIFTS THAT REDUCE STANDARD OF LIVING: a donor who becomes ill, faces care costs, or has reduced income in later years may find that the s.21 gift now consumes income needed for living. If the donor starts drawing on capital to meet living expenses BECAUSE the gift has been made — the exemption fails. FIX: review the gift amount annually against current income; reduce or stop giving if income falls; (5) PITFALL — LOANS DRESSED AS GIFTS: gifts that are in fact loans (with an expectation of repayment) do not qualify for s.21 — or for any IHT exemption. Keep gifts and loans completely separate; (6) PITFALL — CLAIMING S.21 FOR THE FIRST TIME ON DEATHBED: a donor who starts a 'gift programme' in the final weeks of life faces intense HMRC scrutiny. The formation of normal habit requires time. FIX: start the gift programme early, while health is good; establish the pattern over several years; (7) COMBINING WITH OTHER EXEMPTIONS: s.21 can be used alongside the £3,000 annual exemption and the £250 small gifts exemption — they are not mutually exclusive.
