Reporting Inheritance Tax After Death

HMRC needs to see the figures behind an estate to confirm there genuinely is no tax to pay, not just take the executor's word for it. Reporting the value, listing assets, debts, gifts made in the years before death, and any reliefs claimed, allows HMRC to check the position and issue the confirmation the Probate Registry needs before granting probate.

Some very small or straightforward estates qualify for simplified reporting requirements, but the underlying principle remains: the value of the estate has to be established and recorded formally as part of the process, not simply assumed.

Valuing an estate means adding up everything the deceased owned at the date of death, property, savings, investments, personal possessions, and business or agricultural assets where relevant, then deducting any outstanding debts and reasonable funeral expenses. Property and significant personal items usually need a professional valuation rather than a rough estimate, since HMRC can query figures that look understated.

Gifts made in the years before death also need to be considered, since certain lifetime gifts can still count towards the estate's value for inheritance tax purposes depending on when they were made and to whom. Our guide on valuing estate for inheritance tax covers this process step by step.

HMRC's reporting requirements vary depending on the size and complexity of the estate, with different processes for excepted estates that clearly fall below the reporting thresholds and for estates that need a fuller account. GOV.UK is the authoritative and current source for which form or online process applies to a given estate, since eligibility criteria and forms are updated periodically.

It is worth checking the current guidance directly rather than relying on older information, since the process has moved increasingly online and requirements have changed in recent years.

Several reliefs and exemptions commonly reduce or eliminate an inheritance tax bill. Assets left to a spouse or civil partner are generally exempt, as are gifts to registered charities. There are also allowances relating to the family home and its transfer to direct descendants, and rules allowing unused allowances to be transferred between spouses, which can significantly increase the amount an estate can pass on tax-free.

Because these reliefs interact and the rules can be detailed, our guide on who pays inheritance tax and on inheritance tax and wills explain the underlying principles, and GOV.UK provides the current thresholds and rates that apply.

In most cases where tax is due, some or all of it needs to be paid before or as part of applying for the grant of probate, which can create a practical challenge since the estate's own bank accounts may be frozen at this stage. Executors sometimes use a specific facility allowing tax to be paid directly from the deceased's accounts, or arrange a loan, to bridge this gap.

Interest is charged on inheritance tax paid late, so it is worth understanding the payment deadlines early in the process rather than discovering them once a bill has already arrived. Again, GOV.UK holds the current deadlines and payment methods.
