1 Your relationship status
This determines which allowances apply to your estate.
Your estate uses a single Nil-Rate Band (£325,000) and Residence Nil-Rate Band (£175,000).
This calculator estimates IHT on second death — typically when IHT becomes payable. Married couples can combine allowances, up to £1,000,000 combined threshold.
If your late spouse did not use their Nil-Rate Band, you may be able to claim a transferred allowance.
2 Properties
Add each property you own. The net value (after mortgage) is used in your estate. Your main residence may qualify for the Residence Nil-Rate Band.
3 Dental practice / business interests i
Business Property Relief (BPR) automatically applies. 100% relief up to £2.5m (£5m for couples), 50% above that.
£
Include goodwill, equipment, and your share in any trading dental business. BPR is applied automatically.
4 Other assets & investments
Add savings, investments, and personal assets. Use the dropdown to prompt yourself on what to include.
5 Pension funds New from April 2027
From 6 April 2027, unused pension funds will be included in your estate for IHT purposes under the Finance Act 2026. This calculator includes your pension value in the estimate.
£
6 Life insurance (not in trust)
Only include policies NOT held in trust. Policies in trust fall outside your estate and should not be included here.
£
7 Other liabilities
Outstanding loans (excluding property mortgages), credit cards, hire purchase, and other debts. These reduce your estate value.
£
8 Gifts made in the last 7 years (optional)
Include significant gifts of money or assets made in the past 7 years. Exclude: small gifts under £250 per recipient per year, the annual £3,000 exemption, and wedding gifts.
