Changes after the issue of the clearance certificate: changes to the value of assets
Increase in value
If a form IHT30 has been issued at a title and the taxpayer offer to pay tax on an increased value at that title you should inform them that the value is settled so far as inheritance tax is concerned and no adjustment is necessary. This only applies to the property covered by the certificate.
The value of the realty in the estate at death has been agreed with the Valuation Office at £100,000. An application for clearance has been received and issued to the personal representatives (IHTM05012) in respect of the property for which they are liable. The personal representatives then sell the property for £120,000 and offer to pay inheritance tax on the increased price. You should politely refuse the taxpayer’s offer as the value has been agreed and is covered by the clearance certificate that has been issued.
The exception to this rule is where you believe that the taxpayer may have failed to disclose a material fact (IHTM40143) affecting the valuation of the asset before the certificate was issued.
Decrease in value
If the taxpayer claims that the value of any property in the estate should be decreased you should deal with their claim on its merits whether or not a certificate has been issued at that title.
