About this tool

Enter the value of the estate and the part that is the family home passed to children or grandchildren. Tick the spouse option if a late spouse's allowance can be transferred. The tool applies the £325,000 nil-rate band, up to £175,000 residence band and 40 percent on the rest. Rates and thresholds are for the 2026-27 tax year and can change. A guide only, check gov.uk for the official figures.

The allowances

Everyone has a £325,000 nil-rate band. A home left to direct descendants adds a residence nil-rate band of up to £175,000, which tapers away by £1 for every £2 the estate is over £2 million. A surviving spouse can use their late partner's unused allowances, which doubles the figures.

Example

A £650,000 estate with a £300,000 home passed to children and no spouse has £500,000 of allowances, so £150,000 is taxed at 40 percent, a bill of £60,000.

Not included

Gifts made in the last seven years, trusts, business and agricultural relief and the reduced 36 percent rate for charity gifts are not modelled. Take advice for a larger estate.

計算例

With the boxes at their starting values (Total value of the estate (£): 650000; Value of the home left to children (£): 300000; Late spouse's allowance can be used: No), the tool shows: Total allowances (£): 500,000; Taxable estate (£): 150,000; Share of the estate paid as tax: 9.2%; Left to beneficiaries (£): 590,000; Inheritance tax (£): 60,000. Change any box to see your own numbers. The result updates as you type, and nothing leaves your browser.

最良の結果を得るためのヒント

結果を信頼する前にすべての項目を確認してください。数字がひとつ違うだけで答え全体が変わります。給与明細、請求書、証明書、契約書にある正確な数字を使い、計算した日付を控えておきましょう。税率、しきい値、ルールは随時変わるため、税金、手数料、法的な事柄については結果を概算とみなし、このページに記載された公式情報源で確認してください。シナリオは何度でも試せます。何も保存・送信されず、ページを再読み込みすると入力欄はクリアされます。
