Inheritance Tax in UK

The UK has an inheritance tax charged on the value of the deceased's estate above a threshold. The current threshold is £325,000.

Above this threshold, inheritance tax is charged at 40%. There is an additional threshold of £175,000 that can transfer to a surviving spouse or civil partner without incurring inheritance tax.

This means married couples and civil partners have a combined threshold of £500,000 before inheritance tax applies.

Also, direct descendants like children can also receive an additional threshold of £325,000 from a parent before tax applies. Other relationships have no special additional threshold.

Assets jointly owned between spouses and civil partners are exempt from UK inheritance tax regardless if they exceed the thresholds.

The inheritance tax returns and payments are due 6 months after death in the UK. The personal representatives (executors) of the estate are responsible for valuing assets, calculating tax, and paying what is owed.

For UK residents, all assets are subject to inheritance tax regardless of asset location. While non-residents only pay inheritance tax on UK assets.

How inheritance tax calculator work?

Our inheritance tax calculators will first ask you to input the total value of the estate being inherited. This includes all assets like real estate, financial accounts, personal property, etc.

Next, it will ask about the relationships of the beneficiaries to the deceased. Beneficiary categories like children, siblings, and relatives have different tax rates.

The calculator will then apply the inheritance tax rate according to the law for the amount being inherited by each beneficiary based on their relationship.

Most jurisdictions have an exemption for spouses, and sometimes exemptions for assets going to charities or the state. Our calculator will account for this too.

Finally, it will add up the inheritance tax to estimate the total tax liability. This helps beneficiaries understand the potential tax implications before assets are distributed.
