Section G: calculation of rate of tax 

Related trusts  

We need to know about any about any others trusts set up by settlor on the same day. 

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, we no longer take into account the historic value of non-relevant property, for example excluded property and ‘special trusts’. 

Same day additions (anniversaries on or after 18 November 2015) 

If the settlor added any assets to another trust on the same day, which increased the value of the trust by more than £5,000, we will take this into account to calculate the rate of tax charged. 

Exit charges 

You need to tell us about any exit charges that arose during the 10-year period ending on the anniversary date.  

When working out the total value for box G9, you should not include any parts that are eligible for relief. For example, assets valued at £100,000 ceased to be relevant property. Business relief is allowable at 50%. So, the amount you should include is £50,000.   

Chargeable transfers 

You must tell us if the chargeable transfer resulted in the value of the trust being increased. It does not matter whether assets were transferred into the trust itself. The test is if, as a result of the chargeable transfer made by the settlor, the value of the trust was increased. Ignore any transfers made on the day the settlement was made. 

For box G14, if more than one transfer met the conditions set out at box G12, you’ll need to calculate the value of the chargeable transfers made in the 7 years ending immediately before each transfer. When you have done that chose the highest result enter the value in box G14. 

Nil rate band 

For box G15, enter the higher value of boxes G11 and G14.  

If the amount in box G16 is more than the total chargeable value of the transfer at box F11, it means there’s no Inheritance Tax due on this transfer and you should continue from section J and complete the declaration. 

Section H: working out of the tax payable 

Additional tax relief for added property 

The initial rate of Inheritance Tax will be reduced to reflect the time that property was not relevant property.  

The 10-year period is divided into 40 quarters. For example, if some of the property at the anniversary has only been in the settlement for 5 years (20 quarters) then the rate on that property will be half of the initial rate given in box H10. 

Use the Inheritance Tax quarters calculator to give you the number of complete quarters.  

Fill in the tables at boxes H15 and H16 to work out the additional relief on assets that were added to the trust. Enter each asset on a separate line. 

Find more guidance and examples about relief for assets that have been relevant property for less than the full 10 years. 

Interest and payment deadlines for the 10-year anniversary charge 

Inheritance Tax is due no later than 6 months after the end of the month in which the chargeable event occurred. 

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 H19.  

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  

Find out the rules for disclosure of tax avoidance schemes.
