Probate calculator England & Wales · rules as at 9 October 2026

Disclaimer

This is an estimate, not advice

Probate Calculator provides general information and an automated estimate. It is not tax advice, legal advice or financial advice, and nothing on this site should be relied on as such.

We are not authorised by the Financial Conduct Authority and we do not provide regulated advice. The calculator performs arithmetic on figures you supply and explains the rules it has applied. It does not recommend any product, investment or course of action.

Before acting on anything you read here, take advice from a qualified professional — a solicitor, chartered tax adviser, accountant or FCA-authorised financial adviser — who can consider your full circumstances.

No reliance

Inheritance Tax depends on facts and details that a calculator cannot capture: the precise terms of a will, the nature and history of each asset, domicile and residence, trust arrangements, the conduct of past gifts, and the interaction of reliefs. Two estates with identical headline values can produce very different liabilities.

We make no representation or warranty that the estimate is accurate or complete, and we accept no liability for any loss arising from reliance on it. Where the result matters, have it checked.

Nothing on this page excludes or limits any liability that cannot be excluded or limited by law.

What the calculator does not model

Deliberately out of scope:

  • Trusts of any kind — the relevant property regime, ten-year charges, exit charges
  • The residence nil-rate band downsizing addition (a home sold or downsized on or after 8 July 2015)
  • Gifts with reservation of benefit
  • Quick succession relief and double taxation relief
  • Non-UK domicile and long-term-residence cases
  • Woodlands relief and heritage property conditional exemption
  • The option to pay tax by instalments
  • The joint ownership discount (enter the discounted share value yourself)
  • Normal expenditure out of income — explained in the gifts guide rather than computed

If any of these apply, the result will be wrong, usually materially.

Figures and dates

Tax rates and thresholds change, and some of the rules modelled here are new. Rules on this site are current as at 9 October 2026.

These values in particular are flagged as requiring confirmation against current HMRC and GOV.UK guidance:

  • Business & Agricultural Property Relief £1m allowance (from 6 April 2026)
  • Nil-rate band freeze end date

Always check the current position on GOV.UK before acting.

Jurisdiction

Inheritance Tax is a UK-wide tax. The probate information on this site — application fees, excepted estates, timelines and process — applies to England & Wales only. Scotland uses confirmation and Northern Ireland has its own procedure, both differing in process, forms and fees.
