IHT for Single People UK: Inheritance Tax Planning When You Are Not Married or in a Civil Partnership (2026)
A single person has no spousal exemption, no transferred nil-rate band, and a maximum IHT threshold of £500,000 (NRB + RNRB, if the home passes to children). Everything above is taxed at 40%. Systematic lifetime gifting, AIM shares, a charitable legacy, and whole-of-life insurance in trust are the key planning levers — and they need to start early.
| Situation | NRB | RNRB | Total Threshold |
|---|---|---|---|
| Single person, home to children | £325,000 | £175,000 | £500,000 |
| Single person, no children (or home not to descendants) | £325,000 | Nil | £325,000 |
| Married couple (second death) — home to children | £650,000 | £350,000 | £1,000,000 |
| Married couple (second death) — no children | £650,000 | Nil | £650,000 |
| Widow/widower (used full spousal exemption) — home to children | £650,000 | £350,000 | £1,000,000 |
RNRB tapers for estates above £2,000,000 (£1 withdrawal per £2 over £2m, fully withdrawn at £2,350,000/£2,700,000 for single/couple).
IHT Planning for Single People: A Complete Guide
The IHT threshold for a single person: £325,000 or £500,000
A single person (not married, not in a civil partnership) has the following IHT thresholds: (1) Nil-rate band (NRB): £325,000 (frozen until at least April 2030). (2) Residence nil-rate band (RNRB): £175,000 — available where the deceased's home (or a share of it) passes to direct descendants (children, stepchildren, grandchildren) on death. The combined threshold for a single person who owns a home and leaves it to children: £325,000 + £175,000 = £500,000. If the estate exceeds £2,000,000 net: the RNRB tapers by £1 for every £2 over £2,000,000 — the RNRB is fully withdrawn at estates above £2,350,000. No RNRB if no children (or no home passing to direct descendants): a single person without children, or who leaves their home to a sibling, friend, or partner (not a direct descendant), loses the RNRB — leaving only the £325,000 NRB. Comparison with married couple: on the second death, a married couple can have a combined NRB of £650,000 + RNRB of £350,000 = £1,000,000. A single person's threshold is half (or less): the NRB and RNRB cannot be doubled — they have only what they personally own.
No spousal exemption: every transfer is a PET or taxable
The spousal exemption (s18 IHTA 1984) allows assets to pass between married couples and civil partners free of IHT — unlimited amounts, no seven-year clock. For a single person, this exemption does not exist. Any gift of assets from a single person to another individual (child, sibling, friend) is: (1) A potentially exempt transfer (PET — s3A IHTA 1984): if the recipient is an individual, the gift falls out of the IHT estate if the donor survives seven years. In years 3–7, taper relief reduces the IHT charge. (2) A chargeable lifetime transfer (CLT): if the gift goes to a trust (relevant property regime), IHT at 20% applies if the cumulative CLTs in the preceding seven years exceed the NRB. For single people, this means every gift starts a seven-year clock — there is no exempt transfer mechanism that avoids this. The annual exemption (£3,000 per tax year — s19 IHTA) and normal expenditure from income (s21 IHTA) provide immediate exemption from IHT, without a seven-year clock.
Annual gifting strategy for single people
For a single person with an estate above the NRB, a systematic annual gifting strategy is the most accessible IHT planning tool. Available exemptions: (1) Annual exemption — s19 IHTA 1984: £3,000 per tax year, with one year's carry-forward if unused in the prior year (maximum £6,000 in a year if the prior year's was unused). Can be split across any number of recipients. (2) Small gifts exemption — s20 IHTA 1984: unlimited separate gifts of £250 or less to any number of recipients per tax year. Cannot be combined with other exemptions for the same recipient. (3) Normal expenditure from income — s21 IHTA 1984: uncapped exemption for regular gifts from surplus income, provided: the gifts are habitual/regular, made from income (not capital), and after paying them the donor retains sufficient income for their usual standard of living. Keep records (income, outgoings, gift amounts — to support form IHT403 if challenged). (4) Wedding gifts: relevant if children or grandchildren are marrying — £5,000 per child, £2,500 per grandchild. Over 20 years, a single person using only the £3,000 annual exemption removes £60,000 from the estate — saving £24,000 in IHT. Combined with normal expenditure from income (say £5,000/year from pension income), £160,000+ can be removed over 20 years.
Maximising the RNRB: leave the home to direct descendants
For a single person who owns their home, the RNRB (Residence Nil-Rate Band — s8D IHTA 1984) provides an extra £175,000 IHT threshold — but only where the home (or a qualifying share) passes to direct descendants on death. Direct descendants for RNRB purposes: children (natural, adopted, stepchildren, foster children), grandchildren, great-grandchildren — and their spouses/civil partners and widows/widowers. NOT qualifying: siblings, nieces and nephews, friends, charities, trusts (unless for the benefit of direct descendants within 2 years under s144 IHTA). Ensuring the will secures the RNRB: if you have children or grandchildren, make sure the will leaves the family home (or a share of it) to them directly (or to a qualifying trust for their benefit). A will leaving everything to a charity or friend means the RNRB is lost — giving up £175,000 of IHT threshold (£70,000 of IHT saved). Downsizing addition (s8FA IHTA 1984): if you have downsized from a more valuable home after 8 July 2015, you may be entitled to a 'downsizing addition' — a portion of the RNRB based on what the old home would have attracted. The home must have been owned at the time of downsizing, and the will must leave other estate assets to direct descendants.
AIM shares and BPR: growing the estate outside the IHT net
Single people with significant liquid wealth and a higher risk appetite can invest in AIM-listed shares that qualify for Business Property Relief (BPR — s105(1)(bb) IHTA 1984). After holding AIM shares in qualifying trading companies for two years, the shares are 100% exempt from IHT (up to the £1,000,000 combined BPR/APR cap from April 2026; above £1m the relief is 50%). This is available to single people on exactly the same basis as married couples. The difference for single people: there is no ability to transfer assets to a spouse to split the BPR investment between two estates; the entire AIM portfolio is in one estate. From April 2026: the £1m BPR cap means AIM portfolios above £1m attract 50% BPR (effective 20% IHT rate on the excess). AIM ISA: AIM shares can be held in an ISA — the ISA wrapper provides income tax and CGT benefits during life, and the BPR on qualifying shares removes them from the IHT estate after 2 years. Note: not all AIM shares qualify for BPR — investment trusts, holding companies of investment portfolios, and property companies do not qualify. Specialist AIM BPR portfolio managers offer diversified portfolios of qualifying AIM shares.
Charitable legacy: the 36% reduced IHT rate for single people
A single person whose estate exceeds the NRB + RNRB faces 40% IHT on the excess. Leaving at least 10% of the net estate to charity reduces the IHT rate to 36% (s36 IHTA 1984 — see iht-charity-legacy-uk for full analysis). For a single person, the net estate is: gross estate − NRB (£325,000) − RNRB (if applicable, £175,000). Example: single person, no children, estate £500,000. NRB: £325,000. Taxable estate: £175,000. Without charity: IHT = 40% × £175,000 = £70,000. With 10% net estate to charity (£17,500): charity exempt; IHT = 36% × £157,500 = £56,700. Residuary beneficiaries (e.g. siblings, friends): £500,000 − £56,700 IHT − £17,500 charity = £425,800 (vs £430,000 without charity gift). In this example, the family gives up only £4,200 net to create a £17,500 gift to charity. For estates significantly above the NRB, the charitable 36% rate is even more powerful. Use a percentage residuary legacy (not a fixed sum) to reliably hit the 10% threshold.
Whole-of-life insurance in trust: funding the IHT bill
For a single person, there is no surviving spouse to inherit the estate tax-free on first death and potentially use the full estate to pay IHT on a second death. Instead, the entire IHT liability falls at once, on one death. A whole-of-life policy written in trust provides cash on death — outside the IHT estate (the trust owns the policy) — to fund the IHT bill directly. This prevents the executor having to sell the family home or investments to raise cash to pay HMRC. The premium payments (monthly or annually from surplus income) may qualify as normal expenditure from income (s21 IHTA 1984 — immediately IHT-exempt). For single people without children: the trust beneficiaries are typically siblings, nieces and nephews, or close friends — named in the letter of wishes. A discretionary trust gives the trustees flexibility to allocate the payout as needed. Calculating the right level of cover: (gross estate) − (NRB £325,000) − (RNRB if applicable £175,000) − (BPR/APR exempt assets) = taxable estate × 40% = IHT liability. This is the sum assured needed. Review periodically as the estate value changes.
Frequently Asked Questions
What is the inheritance tax threshold for a single person in 2026?
A single person (not married, not in a civil partnership) has: (1) Nil-rate band (NRB): £325,000 (frozen until at least April 2030). (2) Residence nil-rate band (RNRB): up to £175,000 — available if the home passes to direct descendants (children, grandchildren) on death. Combined maximum threshold: £500,000 (NRB + RNRB). If you have no children or are leaving the home to someone who is not a direct descendant (sibling, friend), the RNRB does not apply — leaving only £325,000. There is no spousal exemption and no transferred NRB (available only to widows/widowers). A married couple's combined threshold can reach £1,000,000 — double that of a single person.
Can a single person reduce their inheritance tax?
Yes. Key strategies for single people: (1) Annual gifting exemption (£3,000/yr — s19 IHTA 1984) — immediately IHT-exempt, no 7-year clock; (2) Normal expenditure from income (s21 IHTA 1984) — unlimited regular gifts from surplus income; (3) AIM shares (BPR 100% after 2 years — up to £1m cap from April 2026); (4) Charitable legacy — 36% IHT rate if 10%+ of net estate to charity (s36 IHTA 1984); (5) Whole-of-life policy in trust — funds IHT bill on death outside the estate; (6) Ensure will leaves home to direct descendants to secure RNRB (£175,000). For single people, these strategies are more urgent than for couples — there is no first-death spousal exemption to defer the IHT bill.
Does a single person get the residence nil-rate band?
Yes — if the home passes to direct descendants on death. Direct descendants include children (natural, adopted, stepchildren, foster children), grandchildren, great-grandchildren, and their spouses/civil partners. The RNRB is £175,000 per person (not doubled as for couples). The RNRB tapers for estates above £2,000,000 (£1 withdrawal for every £2 over £2,000,000). If you have no children or are leaving the home to non-descendants (siblings, friends, charities), the RNRB does not apply — leaving only the £325,000 NRB. Check your will is drafted to secure the RNRB if you have children.
Is IHT worse for single people than married couples?
Yes — significantly. A married couple has: (1) Spousal exemption (s18 IHTA 1984) — unlimited transfers between spouses, tax-free; (2) Transferred NRB (s8A) — unused NRB from the first death transfers to the second estate, doubling the NRB to £650,000; (3) Transferred RNRB (s8G) — similarly doubling to £350,000; (4) Combined threshold of up to £1,000,000. A single person has none of these — only their own NRB (£325,000) and RNRB (£175,000). The entire IHT liability falls in one event (single death), not deferred across two deaths. Lifetime planning (gifting, BPR, insurance in trust) is therefore more time-sensitive for single people.
What happens to a single person's estate with no children?
A single person with no direct descendants (no children, no grandchildren) cannot use the RNRB (£175,000) — the IHT threshold is only the NRB (£325,000). Beneficiaries who are not direct descendants (siblings, nieces and nephews, friends) receive the estate above £325,000 net of IHT at 40%. Planning becomes particularly important: lifetime gifts to nieces/nephews are PETs (7-year clock); charitable legacy (36% rate if 10%+ to charity) can reduce IHT; AIM shares BPR removes qualifying shares from the estate; whole-of-life in trust funds the IHT bill. Consider whether forming a civil partnership (or marrying) would be appropriate — if you have a long-term partner, this would give both partners the full spousal exemption and transferred NRB.
A Will Is the Foundation of Single Person IHT Planning
For a single person, the will determines whether the RNRB is available, whether the charitable 36% rate applies, and who your estate goes to. Without a will, intestacy rules apply — and they may not reflect your wishes or maximise your IHT position. WillSafe will kits make it easy to put the right plan in place.
