Qualifying the certificate: instalments
If the taxpayer is paying by instalments (IHTM30191) and the application is made on form IHT30 you do not have to qualify the certificate.
If, however, the application is made on an earlier version of form IHT30, such as Cap30, you should still issue the certificate but it should specifically exclude the property on which instalments are outstanding. You should write
‘Save and except (that part of) the property on which inheritance tax is being paid by instalments’
above your signature and authorisation stamp.
