  • IHT rate: 40% (or 36% if 10%+ left to charity)

Frequently Asked Questions

What is the Inheritance Tax threshold?

The nil-rate band (NRB) is £325,000. Estates valued below this pay no IHT. An additional residence nil-rate band (RNRB) of up to £175,000 is available when passing a main residence to direct descendants, giving a potential total of £500,000 per person.

Can married couples combine their IHT allowances?

Yes. When the first spouse dies, any unused nil-rate band and residence nil-rate band can transfer to the surviving spouse. This means a married couple can potentially pass on up to £1,000,000 tax-free.

What is the reduced rate for charitable legacies?

If you leave at least 10% of your net estate to charity, the IHT rate is reduced from 40% to 36% on the taxable portion. This can make charitable giving effectively cost-neutral in some cases.

How do gifts affect Inheritance Tax?

Gifts made more than 7 years before death are exempt. Gifts within 7 years may be taxed on a sliding scale (taper relief). An annual exemption of £3,000 in gifts is always tax-free, and small gifts up to £250 per person are exempt.
