Taxes Management Act 1970 (c. 9)
7In Part 4, after section 43C insert—
“43DClaims for double taxation relief in relation to petroleum revenue tax
(1)This section has effect in relation to a claim for relief under sections 2 to 6 of TIOPA 2010 in relation to petroleum revenue tax.
(2)The claim shall be for an amount which is quantified at the time when the claim is made.
(3)If, after the claim has been made, the claimant discovers that an error or mistake has been made in the claim, the claimant may make a supplementary claim within the time allowed for making the original claim.
(4)Schedule 1A to this Act applies as respects the claim, but as if the reference in paragraph 2A(4) to a year of assessment included a reference to a chargeable period.
(5)The claim may not be made more than 4 years after the end of the chargeable period to which it relates, but this is subject to any provision of the Taxes Acts prescribing a longer or shorter period.
(6)If the claim or a supplementary claim could not have been allowed but for the making of an assessment to petroleum revenue tax after the end of the chargeable period to which the claim relates, the claim or supplementary claim may be made at any time before the end of the chargeable period following that in which the assessment is made.
(7)In this section “chargeable period” has the same meaning as in the Oil Taxation Act 1975 (see section 1(3) and (4) of that Act, under which a period that is a chargeable period ends with 30 June or 31 December and, apart from the first chargeable period in relation to an oil field, is a period of 6 months).”
