Premiums paid during a person’s lifetime on his own life may be regarded as normal expenditure out of income and therefore exempt from inheritance tax. Such premiums are not ‘normal expenditure’ if an annuity was purchased on his life unless they were not associated operations, i.e back to back. Policies and annuities are not regarded as associated operations if, first, the policy was issued on full medical evidence of the insured’s health, and, secondly, it would have been issued on the same terms if the annuity had not been bought.
