UK Inheritance Tax Calculator & Planning — Inheritance Planner

Inheritance Planner provides free inheritance tax tools and expert guidance for UK families. Use our free IHT calculator to find out how much inheritance tax your estate may owe, discover legitimate ways to reduce the bill, and get matched with a vetted probate solicitor if you need professional help.

Free Inheritance Tax Calculator

Our step-by-step calculator covers all the main inheritance tax scenarios for England, Wales, Scotland, and Northern Ireland. Enter your estate value, property details, gifts made in the last seven years, and family situation to get an instant estimate of your inheritance tax liability and the forms you need to complete.

Gifting Strategy Planner

Gifts made during your lifetime can reduce the value of your estate for inheritance tax purposes. Our Gifting Strategy Planner lets you track gifts against the seven-year rule, see taper relief applied automatically, and model how much tax a future gift could save your family. The annual exemptions guide explains every allowance available in the 2025/26 tax year.

Will Health Check

An outdated will can expose your estate to unnecessary inheritance tax and leave your family without legal protection. Our free Will Health Check asks eleven questions about your current will — covering beneficiaries, executors, tax efficiency, lasting powers of attorney, and more — and gives your will a traffic-light rating with personalised recommendations.

Estate Inventory Builder

Executors need a complete picture of an estate before they can apply for probate. The Estate Inventory Builder helps you record every asset, liability, insurance policy, and important document in one place, with a real-time inheritance tax estimate updating as you add items.

Find a Probate Solicitor

If your estate is complex — involving overseas assets, trusts, business interests, or significant inheritance tax — our free matching service connects you with a vetted specialist solicitor. Tell us about your situation and we match you with the right expert. There is no obligation and no charge for the introduction.
