Finance Act 1960

7 (1) Whenever any assessment to income tax for any year of assessment has been made on any person by virtue of section fifty-one of this Act which is based wholly or partly on the profits of a trade or business carried on by him, an assessment to the profits tax may, subject to sub-paragraph (2) of this paragraph, be made on him for any chargeable accounting period ending after the beginning of the period during which those profits arose.

(2) Without prejudice to any power exercisable under section twenty-seven of the Finance Act, 1958, an assessment under this paragraph may be made only before the expiration of two years from the final determination of the tax covered by the said assessment to income tax, and only for the purpose of making good to the Crown a loss of tax attributable to the said person's neglect.

(3) In determining the amount of the tax to be charged for any chargeable accounting period in any assessment made under this paragraph effect shall be given, if the person to be assessed so requires, to any deduction or relief to which he would have been entitled for that period on an application made within the time allowed by the enactments relating to the profits tax.
