Isokon includes the IHT400 as well as the ancillary tax forms:
IHT30 - Application for a Clearance Certificate
IHT35 - Claim for Relief on Sale of Shares
IHT38 - Claim for Relief on Sale of Land

Isokon also provides forms, which, although not tax forms, are an essential component of probate work:
R185 - which provides to the beneficiaries a statement of their income from the estate
922 - which deals with income arising to the personal representatives, certain other receipts, expenses, amounts paid to the beneficiaries and the amounts treated as their income.
Death Certificate Verification Form - this is commonly sent out to correspondents of the estate instead of a certified copy of the death certificate.
