Value Added Tax Act 1994

78 Interest in certain cases of official error

(1) Where, due to an error on the part of the Commissioners, a person has—

(a) accounted to them for an amount by way of output tax which was not output tax due from him and which they are in consequence liable to repay to him, or

(b) failed to claim credit under section 25 for an amount for which he was entitled so to claim credit and which they are in consequence liable to pay to him, or

(c) (otherwise than in a case falling within paragraph (a) or (b) above) paid to them by way of VAT an amount that was not VAT due and which they are in consequence liable to repay to him, or

(d) suffered delay in receiving payment of an amount due to him from them in connection with VAT,

then, if and to the extent that they would not be liable to do so apart from this section, they shall pay interest to him on that amount for the applicable period, but subject to the following provisions of this section.

(2) Nothing in subsection (1) above requires the Commissioners to pay interest—

(a) on any amount which falls to be increased by a supplement under section 79; or

(b) where an amount is increased under that section, on so much of the increased amount as represents the supplement.

(3) Interest under this section shall be payable at such rates as may from time to time be prescribed by order made by the Treasury; and any such order—

(a) may prescribe different rates for different purposes; and

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

and the first such order may prescribe, for cases where interest runs from before the date on which that order is expressed to come into force, rates for periods ending before that date.

(4) The “applicable period” in a case falling within subsection (1)(a) or (b) above is the period—

(a) beginning with the appropriate commencement date, and

(b) ending with the date on which the Commissioners authorise payment of the amount on which the interest is payable.

(5) In subsection (4) above, the“appropriate commencement date”—

(a) in a case where an amount would have been due from the person by way of VAT in connection with the relevant return, had his input tax and output tax been as stated in that return, means the date on which the Commissioners received payment of that amount; and

(b) in a case where no such payment would have been due from him in connection with that return, means the date on which the Commissioners would, apart from the error, have authorised payment of the amount on which the interest is payable;

and in this subsection“the relevant return” means the return in which the person accounted for, or (as the case may be) ought to have claimed credit for, the amount on which the interest is payable.

(6) The “applicable period” in a case falling within subsection (1)(c) above is the period—

(a) beginning with the date on which the payment is received by the Commissioners, and

(b) ending with the date on which they authorise payment of the amount on which the interest is payable.

(7) The “applicable period” in a case falling within subsection (1)(d) above is the period—

(a) beginning with the date on which, apart from the error, the Commissioners might reasonably have been expected to authorise payment of the amount on which the interest is payable, and

(b) ending with the date on which they in fact authorise payment of that amount.

(8) In determining in accordance with subsection (4), (6) or (7) above the applicable period for the purposes of subsection (1) above, there shall be left out of account any period referable to the raising and answering of any reasonable inquiry relating to any matter giving rise to, or otherwise connected with, the person’s entitlement to interest under this section.

(9) In determining for the purposes of subsection (8) above whether any period is referable to the raising and answering of such an inquiry as is there mentioned, there shall be taken to be so referable any period which—

(a) begins with the date on which the Commissioners first consider it necessary to make such an inquiry, and

(b) ends with the date on which the Commissioners—

(i) satisfy themselves that they have received a complete answer to the inquiry, or

(ii) determine not to make the inquiry or, if they have made it, not to pursue it further,

but excluding so much of that period as may be prescribed; and it is immaterial whether any inquiry is in fact made or whether it is or might have been made of the person referred to in subsection (1) above or of an authorised person or of some other person.

(10) The Commissioners shall only be liable to pay interest under this section on a claim made in writing for that purpose.

(11) No claim shall be made under this section after the expiry of 6 years from the date on which the claimant discovered the error or could with reasonable diligence have discovered it.

(12) In this section—

(a) any reference to receiving a payment from the Commissioners includes a reference to the discharge, by way of set-off, of their liability to make it; and

(b) any reference to a return is a reference to a return required to be made in accordance with paragraph 2 of Schedule 11.
