How to fill in form IHT100h
Published 12 August 2024
When you should complete this form
You should complete form IHT100h to tell HMRC about assets that have stopped being held in an ‘18 to 25’ trust.
This is a trust where one parent has died, and the beneficiary will become entitled to their share of the assets at an age between 18 and 25 years old. It does not include trusts for bereaved minors.
Do not use this form if the beneficiary either:
-
has not taken control of the assets at the age of 25
-
no longer benefits from the trust property and income
You should fill in form IHT100e instead.
Before you start
You should complete all fields. If information is missing we may not be able to deal with your form.
Make sure you have read all the relevant notes before you start completing the form.
Some types of assets could be included in more than one section of the form, such as stocks and shares, so make sure you put them in the right section. Do not include the same asset in more than one section.
You do not need to send us copies of documents (for example, a letter from a bank with the balance in an account, or evidence of liabilities) unless we specifically ask you to do so.
You must keep all documents that you have used to fill in the form as we may ask you for some or all of them later.

-
at the start of the trust
-
before the date of the charge
You must also tell us about assets the settlor added to other trusts on the same day this trust started.
You must value each asset on the date it was added to the trust. Do not include any reliefs or exemptions.
Related trusts
We need to know about any others trusts set up by the settlor on the same day as this trust. We do not need to know about charitable trusts.
The assets in these other trusts should be valued at the date on which the trust started. If the charge is on or after 18 November 2015, you should only include the assets added to 18 to 25 trusts.
Nil rate band
You should enter the nil rate band at the date of the event in box G8.
You can find the rates and thresholds in ‘Inheritance Tax nil rate bands, limits and rates (IHT400 rates and tables)’.
Section H: working out the tax
This section is optional. If you do not want to work out the tax yourself you can leave section H blank and continue from section I.
Appropriate fraction
Relief is given for the time that the assets have been in the trust. It’s worked out based on the completed ‘quarters’ since the trust began.
Use the quarters calculator tool to work out the number of complete quarters between the start of the trust and the date of the charge.
The maximum number of quarters is 28 for the 7 year life of the trust.
Grossing
If the trustees are paying the tax due out of the assets that remain in the trust, you must adjust the figure in box H10 to take this into account. This is called ‘grossing up’.
You should use the following calculation to work out the gross effective tax rate.
(H10 ÷ (100 – H10)) × 100 = gross effective tax rate
You should enter the adjusted figure in box H12.
If the total tax rate has been grossed up, you should work out the figure for box H13 by multiplying box F11 by H12.
Working out the interest on the total tax payable
Inheritance Tax is due no later than 6 months after the end of the month the transfer was made.
If your payment is after the due date, interest is added to any unpaid tax and is charged at a daily rate.
You should use the Inheritance Tax interest calculator to work out the amount of interest due on your payment and complete the summary table in box H20.
If you’re paying the tax due before the due date, continue to section I.
Section I: authority for repayment of Inheritance Tax
If we need to repay any Inheritance Tax, we’ll make the payment directly to the bank account in the names of all the people who have signed the form by Faster Payments.
If you do not have a bank account in those names, it may be difficult for you to obtain the repayment. To avoid any difficulties, give the details of the account you want the repayment paid into.
Section J: disclosure of tax avoidance scheme
You should include both the:
-
scheme or promotor reference number if you’ve been given one
-
tax year or date when the tax advantage is expected
