Section G: rate of tax charge before the first 10 year anniversary 

You should only complete this section if the charge is before the 10 year anniversary of the trust. Continue from ‘Section I’ if the event happened more than 10 years after the date the trust was started. 

You should use this section to tell us about the historic value of the assets added to the trust by the settlor before the date of the charge. You must also tell us about assets the settlor added to other trusts.  

You must value each asset on the date it was added to the trust. Do not include any reliefs or exemptions. 

If non-relevant property became relevant property 

You must tell us if any assets added to the trust became relevant property before the date of the charge. For example, if the trust was a qualifying interest in possession, but later became relevant property.  

You need to tell us the:  

• date each asset became relevant property 

• value of the asset when it became relevant property 

You can group together any assets that became relevant property on the same day.  

Related trusts 

We need to know about any about any others trusts set up by 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, we no longer take into account the historic value of non-relevant property, for example excluded property and ‘special trusts’. 

Same day additions (exit charges 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. 

Nil rate band  

You only need to tell us about any chargeable transfers if the trust was set up on or after 24 March 1974. Each transfer should be valued on the date it was made.  

You should enter the nil rate band at the date of the charge in box G15.  

You can find the rates and thresholds in ‘Inheritance Tax nil rate bands, limits and rates (IHT400 rates and tables)’.  

If the ‘total nil rate band available’ is nil the initial rate of Inheritance Tax will be 6%.  

Section H: working out the tax payable 

You should only fill in this section if you’ve completed section G.  

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.  

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 H12 to take this into account. This is called ‘grossing up’.  

You should use the following calculation to work out the gross effective tax rate.  

(H12 ÷ (100 – H12)) × 100 = gross effective tax rate 

You should enter the adjusted figure in box H14.  

If the total tax rate has been grossed up, you should work out the figure for box H13 by multiplying box F11 by H14. 

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 date of exit has only been relevant property for 5 years (20 quarters) then the rate on that property will be half of the initial rate given in box H12.  

Use the quarters calculator tool to work out the number of complete quarters.   

Fill in the tables at boxes H18 and H19 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.

Example 

The trust start date was 1 January 2010.  

On 1 August 2014 there was a distribution of assets valued at £160,000.  £100,000 of these assets were added to the trust on 1 February 2011. £60,000 of the assets became relevant property on 1 November 2012.  

The total number of complete quarters is 21. This is: 

• 14 quarters between 1 February 2011 and 1 August 2014 

• 7 quarters between 1 November 2012 and 1 August 2014 

The rate from box H12 is 4.8%. 

The following table shows how you should enter this information on the form.  

Value of (added) relevant property	Rate (%)	Complete quarters	Reduction in tax (£)
100,000	4.8	14	1,680
60,000	4.8	7	504

Working out the interest on the total tax payable 

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 rate calculator to work out the amount of interest due on your payment and complete the summary table in box H19.   

If you’re paying the tax before the due date, continue to section K.  

Section I: rate of tax charge after a 10 year anniversary 

You should fill in boxes I6 to I19 using the instructions in ‘section G’ on: 

• related trusts 
• same day additions 
• the nil rate band

You need to tell us the value of the assets at the last 10 year anniversary. You can find this either: 

• on the assessment of tax we sent you 

• in your own records, if you worked out the tax yourself 

We also need to know about any assets: 

• which have become relevant property between the date of the last anniversary and the date of this charge 

• added to the trust between the date of the last anniversary and the date of this charge 

The assets should be valued at the date they were added to the trust or became relevant property.  

Section J: working out the tax payable 

You should use the instructions in ‘section H’ to help you complete boxes J11 to J23. You’ll find information about: 

• the appropriate fraction 

• grossing up 

• additional tax relief for added property

If the tax is being paid from assets that remain in the trust 

You should use the following calculation to work out the gross effective tax rate.  

(J12 ÷ (100 – J12)) × 100 = gross effective tax rate 

You should enter the figure in box J14.  

For box J15, you should multiple box F11 by J14.  

Working out the additional tax relief for added property 

Use the instructions in section H to help you complete the tables in boxes J18 and J19.  

Use the quarters calculator tool to work out the number of complete quarters.   

Working out the interest due  

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 J22.   

Section K: 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 L: 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
