A Plain English Guide to IHT
The Dreaded 40% Tax
Inheritance Tax is a tax on the estate (the property, money, and possessions) of someone who's died. It is famously unpopular, but you only pay the 40% rate on the parts of your estate that sit ABOVE your tax-free allowances.
The Allowances We All Get
- The Basic Rate Band: £325,000Every single person in the UK gets this allowance tax-free.
- The Residence Band: +£175,000Added if you give your main home to your children or grandchildren.
The Power of Marriage
For Inheritance Tax, marriage is incredibly powerful. Any assets passed to a spouse are completely tax-free. Furthermore, the surviving spouse inherits whatever percentage of the late partner's tax-free allowance went unused.
The £1 Million Threshold
By combining two £325k basic allowances and two £175k residence allowances, a married couple can currently pass on exactly £1,000,000 tax-free.
The 7-Year Rule (PETs)
Potentially Exempt Transfers (PETs) mean you can gift unlimited amounts of money during your lifetime. However, if you die within 7 years of making the gift, it gets pulled back into your estate for tax calculation purposes.
Trusts and Insurance
Many wealthy families minimize IHT legally by placing assets into Trusts or using dedicated life insurance policies (written in trust) to cover the eventual HM Revenue & Customs bill, leaving the estate intact for heirs.
