When Inheritance Tax forms are needed
If someone dies and their estate may be worth more than the Inheritance Tax threshold, the personal representatives usually need to complete forms for HMRC. The exact forms depend on the value and type of assets in the estate. In many cases, the forms are needed even if no tax is ultimately payable.
These forms are used to report the estate to HMRC before probate can be granted. If the estate is straightforward and below the relevant threshold, the process is simpler. More detailed forms are required where the estate is larger, contains trusts, or includes complicated assets.
The main Inheritance Tax forms
The most common form is IHT205, which is usually used for excepted estates. This is generally for estates that fall below the Inheritance Tax threshold and do not need a full account. It is normally the simpler option for smaller, uncomplicated estates.
For estates that are not excepted, the main form is IHT400. This is the full Inheritance Tax account and is used when more detailed reporting is needed. It is often submitted with additional schedules that give HMRC more information about the estate’s assets, debts, gifts, and reliefs.
Additional schedules you may need
If you complete form IHT400, you may also need to fill in extra schedules depending on the estate. These can cover property, shares, bank accounts, joint assets, foreign assets, gifts made in the last seven years, and liabilities. Each schedule gives HMRC a clearer picture of the estate’s value.
Some estates may also need forms relating to trusts, business property relief, or agricultural property relief. If there are pensions or insurance policies, these may need to be listed too. The more complex the estate, the more supporting forms are likely to be required.
What happens before probate
The Inheritance Tax forms are usually submitted before probate is applied for. HMRC must receive the correct paperwork so they can check whether any tax is due. In some cases, tax must be paid before probate can be issued.
Executors should gather as much information as possible before starting the forms. This includes property valuations, bank statements, share valuations, outstanding debts, and details of gifts. Accurate information helps avoid delays and reduces the risk of errors.
Getting help with the forms
Inheritance Tax paperwork can be complicated, especially where there are multiple beneficiaries or unusual assets. Many people choose to use a solicitor or probate specialist to make sure the right forms are completed. This can be especially useful if the estate is above the threshold or includes relief claims.
Even for a smaller estate, it is worth checking carefully which form applies. Using the wrong form can delay the probate process. If you are unsure, HMRC guidance or professional advice can help you decide what needs to be completed.
