Inheritance tax (IHT) is a tax that may apply to the value of an estate after someone dies.

However, inheritance tax does not apply to all estates. The UK tax system includes several allowances and thresholds that determine when inheritance tax may become payable.

Understanding these thresholds can help individuals review whether inheritance tax may affect their estate and how estate planning may influence wealth transfer.

HM Revenue & Customs provides detailed guidance on inheritance tax thresholds and allowances here: gov.uk

Quick Summary

This may help you:

  • Understand when inheritance tax may apply
  • Learn what the inheritance tax threshold is
  • Understand the nil-rate band and residence nil-rate band
  • See how inheritance tax allowances work

Before deciding, check:

  • Estate planning
  • Passing wealth to family members
  • Gifting strategies
  • Property inheritance

The Nil-Rate Band

The nil-rate band is the main inheritance tax threshold.

It represents the portion of an estate that can usually be passed on without inheritance tax applying.

Any estate value above this threshold may be subject to inheritance tax, depending on the circumstances and available allowances.

The Residence Nil-Rate Band

In addition to the standard threshold, there is also a residence nil-rate band.

This allowance may apply when a main residence is passed to direct descendants such as children or grandchildren.

The residence nil-rate band can increase the total inheritance tax threshold available to an estate.

HMRC provides further details on residence nil-rate band rules.

Transfers Between Spouses

In many cases, assets passed between spouses or civil partners are exempt from inheritance tax.

This means that inheritance tax is often not applied when assets pass to a surviving spouse.

Unused allowances may sometimes also be transferred between spouses.

Inheritance Tax and Estate Planning

Understanding inheritance tax thresholds can play an important role in estate planning.

Some individuals review how assets are structured when planning how wealth may be passed to beneficiaries.

For example, gifting strategies may influence the value of an estate over time.

Our article on the seven-year rule for gifts explained explains how gifts may affect inheritance tax calculations.

Our guide on passing down wealth: estate planning principles explained also explores how estates may be structured when transferring wealth.
