Inheritance Tax (UK) Calculator
Use our inheritance tax calculator to determine if Inheritance Tax will apply to your estate and, if so, how much.
Your estate includes everything you own, including property, savings, cash and even personal items such as jewellery and art.
Anything you want to pass on to others could be subject to Inheritance Tax (IHT). The current threshold for paying IHT is £325,000. Anything over that value will likely be taxed at 40%.
Our calculator helps you estimate the inheritance tax that may be due on your estate.
Value of business interests or unlisted shares.
Chargeable gifts reduce NRB (taper relief not modelled).
Advanced allowances
Simplified model. Rules can change and personal circumstances vary. Not financial advice.
Shows the size of each element (not additive).
Start at net estate, subtract allowances and charity to get the taxable amount, then subtract IHT — label shows the amount after tax.
Assumptions
- NRB default £325,000; RNRB default £175,000 — tapered by £1 for every £2 of net estate over a threshold (default £2,000,000). Configurable.
- RNRB only considered when the main property is left to direct descendants and is capped by the main property value.
- Gifts in the last 7 years reduce the NRB here; detailed taper relief on gifts is not modelled.
- Charity reduces the taxable estate; IHT rate reduces to 36% if charity ≥ 10% of net estate (approximate baseline test).
- Spouse/civil partner exemption: if the entire estate passes to a spouse/CP, IHT is set to £0 in this model.
- Excludes reliefs such as BPR/APR, trusts and domicile nuances. Values rounded to whole pounds.
Important Information
This calculator provides a general estimate based on current UK Inheritance Tax (IHT) rules and does not constitute financial or legal advice.
This calculator does not consider all exemptions, reliefs, or complex estate structures such as trusts, business assets, or foreign property.
Be aware that gifts made in the last 7 years could be subject to inheritance tax. Additionally, tax laws and thresholds are subject to change.
