Before probate begins, you must estimate the estate's value to see if Inheritance Tax applies. This includes valuing the deceased person's money, property and belongings in order to determine if Inheritance Tax (IHT) is due. This process is important even if you are not sure that any tax will be due.

There is usually no IHT to pay if the estate is valued under £325,000 or if anything above this threshold is left to a spouse, civil partner, charity or amateur sports club. If the person was widowed or passed on their home to children or grandchildren, the threshold may be higher.

To estimate the estate's value, you'll need to account for:

• All assets owned at death (homes, bank accounts, valuables, vehicles, investments etc).
• Any gifts made in the 7 years before death.
• The value of any trusts where the person had a beneficial interest.

You can estimate values yourself or use HMRC’s Inheritance Tax Checker to guide you. The checker helps identify whether IHT is likely to be due, but it does not calculate how much tax is due or notify HMRC.

When valuing assets, include joint property, pensions, or overseas items and assess their market value on the date of death. For gifts, consider their value when given, especially if the deceased still benefited from them (e.g., living rent-free in a gifted home).

You will also need to consider debts and check whether full reporting of the estate to HMRC is required.
