Finance Act 1994

21 (1) Where an assessment is made under any provision of section 56 of this Act, the whole of the amount assessed shall carry interest at the prescribed rate from the reckonable date until payment; but this is subject to sub-paragraph (2) and paragraph 25(7) below.

(2) Sub-paragraph (1) above shall not apply in relation to an assessment under section 56(1) of this Act unless at least one of the following conditions is fulfilled, namely—

(a) that the assessment relates to an accounting period in respect of which either a return has previously been made, or an earlier assessment has already been notified to the person concerned;

(b) that the assessment relates to an accounting period which exceeds three months and begins on the date with effect from which the person was, or was required to be, registered under this Part of this Act.

(3) In a case where—

(a) the circumstances are such that a relevant assessment could have been made, but

(b) before such an assessment was made the tax due or other amount concerned was paid (so that no such assessment was necessary),

the whole of the amount paid shall carry interest at the prescribed rate from the reckonable date until the date on which it was paid; and for the purposes of this sub-paragraph a relevant assessment is an assessment in relation to which sub-paragraph (1) above would have applied if the assessment had been made.

(4) The references in sub-paragraphs (1) and (3) above to the reckonable date shall be construed as follows—

(a) where the amount assessed or paid is such an amount as is referred to in subsection (2) of section 56 of this Act, the reckonable date is the seventh day after the day on which a written instruction was issued by the Commissioners directing the making of the payment of the amount which ought not to have been paid to the person concerned;

(b) in all other cases the reckonable date is the latest date on which (in accordance with regulations under this Part of this Act) a return is required to be made for the accounting period to which the amount assessed or paid relates;

and interest under this paragraph shall run from the reckonable date even if that date is a non-business day, within the meaning of section 92 of the [1882 c. 61.] Bills of Exchange Act 1882.

(5) In this paragraph “the prescribed rate” means such rate as may be prescribed by order; and such an order—

(a) may prescribe different rates for different purposes;

(b) shall apply to interest for periods beginning on or after the date when the order is expressed to come into force, whether or not interest runs from before that date.

(6) Interest under this paragraph shall be paid without any deduction of income tax.
