It is illegal to die in the Houses of Parliament (even though you might think it’s a good idea for some/all politicians).
This exemption is contained in section 154 of the Inheritance Tax Act 1984 and applies where a person was a member of the armed forces and was on active service. It provides that there will be no Inheritance Tax charged on the estate of a person certified by the Ministry of Defence or the Secretary of State as having died from a wound inflicted, accident occurring or disease contracted while on active service, or a disease contracted at some previous time, the death being due to or hastened by the aggravation of the disease during active duty.
