Successive charges relief
If in the 5 years before they died, the deceased inherited money or assets from another person’s estate on which Inheritance Tax
was paid, you may deduct successive charges relief to stop that legacy being taxed twice in a short period of time.
11
Is successive charges relief due?
No
Enter ‘0’ in box 18 and go to box 19
Yes
Follow the instructions below for working out successive charges relief
You’ll need to find out the value of the estate of the first person to die and the amount of Inheritance Tax paid in order to
work out the relief due. You’ll also need to know what the deceased was entitled to receive from the estate. You can find out
this information by asking the executor of the estate of the first person to die.
If you’re deducting successive charges relief enter:
the Inheritance Tax reference of the first person to die
their full name
their date of death
in the ‘Additional information’ boxes on page 16 of form IHT400.

The amount of relief available depends on the number of years between the first and second deaths
and is shown in the table.
For example, if the second death was on 3 March 2007 and the first death was on 17 August 2005, there is
more than one year between the 2 deaths, but less than 2 years, so the percentage reduction would be 80%.

This is the amount of Inheritance Tax
paid on the deceased’s share of the
estate of the first person to die.
You now need to look at how much
relief is due on that amount of tax.
If there were between one and 2 years
between the 2 deaths, then the table
shows that the percentage reduction
would be 80%.
£5,880 x 80 ÷ 100 = £4,704.

Tax that may be paid by instalments
The tax on some types of unsold property and assets may be paid in 10 annual instalments, that is, one instalment
per year for 10 years. The property and assets on which tax may be paid in this way are unsold houses, land, buildings,
some types of shares and the net value of a business or an interest in a business after deduction of Business Relief.
These assets and properties are listed on pages 7 and 8 on form IHT400 in column B. The total value of the assets on which
you may pay the tax by instalments is on form IHT400, box 95, plus box 97 + box 99 (if any) .
As soon as any of the property or assets are sold you’ll have to pay all the remaining tax. If you choose to pay tax
by instalments on these assets you’ll have to pay interest on the outstanding tax.

Instalments due now
You only need to work out the tax that is being paid by instalments if the due date for the first instalment has passed or is less
than 30 days away. Otherwise you can miss out boxes 23 to 39 and go straight to box 40. The first instalment of tax is due on
the last day of the sixth month after the date of death. For example, the deceased died on 17 July 2007, the due date for the
payment of the first instalment is 31 January 2008. The table of due dates below will help you to work out the due date.

Double taxation relief
If foreign tax equivalent to Inheritance Tax was paid on the value of foreign assets, double taxation relief may be due if there
is a double taxation convention between the UK and the other country. If there is no convention, we may still be able to give
‘unilateral relief’. For more information about double taxation relief go to www.gov.uk/inheritance-tax
If you wish to claim double taxation or unilateral relief, enclose with form IHT400 a ‘certificate of tax paid’ from the overseas tax
authority, if you already have one, showing the amount of foreign tax paid. We may ask more questions about the claim after the
Grant is issued. You must also fill in schedule IHT417, ‘Foreign assets’ detailing the assets outside the UK.

Interest
Inheritance Tax is due to be paid on the last day of the sixth month after the date of death. Interest will be due even if you
have not got a Grant by then. Interest will also be due even if we have not contacted you or anybody else (for example, the
trustees of a trust or someone who received a gift from the deceased). The law says that interest will be added to any unpaid tax
after this date. Interest is not a penalty, it compensates the Exchequer for the delay in receiving the money due to it. If you pay
too much tax, we pay interest on the repayment to you.
Interest starts on the first day of the 7th month after the date of death. For example, if the deceased died on 17 July 2007,
interest will be due from 1 February 2008 on all unpaid tax whatever the reason the tax has not been paid. The table below will
tell you the date that interest starts.

Additional interest on tax that’s being paid by instalments when more than one instalment is due
When more than one instalment of tax is due, you’ll have to work out an additional amount of interest
unless the instalments of tax are interest-free.
Interest-free instalments
Instalments of tax are interest-free for certain types of assets as long as the instalments are paid on time.
The assets on which the instalments are interest-free are:
shares or securities, except shares in an investment or property company, which will only qualify if the company is
a holding company of companies, which aren’t investment or property companies
a market maker or discount house in the UK
a business or interest in a business carried on for gain
land which qualifies for agricultural relief
timber
It would be a very unusual situation if you need to work out the interest on these types of assets where the instalments
are being paid late. The IHT400 Helpsheet, ‘Working out the interest on Inheritance Tax payments’ explains what to do:
if the instalments are not interest-free (and most won’t be) for the interest calculator,
go to www.hmrc.gov.uk/tools/inheritancetax/interest-rate-calculator.htm
in the ‘start date for interest’ box on the calculator enter the date from box 55
in the ‘end date for interest’ box on the calculator enter the date the most recent instalment became due
in the ‘Inheritance Tax owed’ box enter the total amount of tax being paid by instalments from box 37

Taper relief
If there is additional tax to pay on lifetime gifts, taper relief may be available. This will apply in the following circumstances:
the total value of gifts must be more than the Inheritance Tax nil rate band
the gifts must have been made between 3 and 7 years before the deceased died
The relief reduces the amount of tax payable on a gift, not the value of the gift itself.
For more information about taper relief go to www.gov.uk/inheritance-tax
Trusts
If the deceased benefited from any assets held in trust shown on Schedule IHT418 and the trustees have not paid the tax with
this account, more tax will be due. We’ll send a calculation of the tax to the trustees named on the Schedule IHT418.
If there are amendments made to the value of the trust assets or the value of the deceased’s estate this will affect both the tax
due on the trust assets and the tax due on the deceased’s estate. If this is the case, we’ll send you more calculations of tax.
What to do when you’ve filled in this form
If you’re filling in this form without the help of a solicitor, another person licensed to provide probate services or other adviser,
send the form to us with your form IHT400 so that we can see how you’ve worked out the tax. Continue filling in the form IHT400
from box 120.
If you’re a solicitor, another person licensed to provide probate services or other adviser, you do not need to send this form to us
if you do not want to, but if you’ve included an amount of successive charges relief in box 18 or double taxation relief in
boxes 36 or 53, send this form to us with the form IHT400 so that we can see how these reliefs were worked out.
Tax payable on gifts and lifetime transfers
The tax and interest shown at box 65 is the tax and interest which is payable now in order for you to be able to obtain a grant of
representation. Depending on the circumstances of the estate, there may be more tax and interest to pay by the person(s) who
received lifetime gifts from the deceased. We may also ask the person(s) who received the gifts for more details of the gifts on a
separate account.
If the deceased made lifetime gifts which were over the Inheritance Tax nil rate band or gifts with reservation, more tax will be
payable and we’ll send calculations of the tax when you’ve sent this form to us. But you should bear in mind that interest becomes
payable if the tax isn’t paid on time. To find out how lifetime gifts are taxed on death, go to www.gov.uk/inheritance-tax
For example, the deceased died on 6 July 2005. The date tax is due is 31 January 2006. The tax being paid
by instalments is £10,000. The first instalment of £1,000 is due on 31 January 2006, the second instalment
on 31 January 2007 and so on. The application for a Grant was made on 18 June 2007, so that 2 instalments
had to be paid at that time. The ‘end’ date in this example would be 31 January 2007.
In the ‘Inheritance Tax owed’ box enter the total amount of tax being paid by instalments (from box 37). In this
example this will be £10,000.
