Oil Taxation Act 1975 section Sch 2 para 13C

Making a claim

Section 13C sets out the time limits and formal requirements for making a claim for relief where petroleum revenue tax has been overpaid or is excessive.

• A claim for overpaid petroleum revenue tax must be made no later than 4 years after the end of the relevant chargeable period.
• Where the overpayment arises because tax was actually paid (or was liable to be paid) in excess, and this was due to a mistake in a return, the relevant chargeable period is the one to which the earliest incorrect return relates.
• Where the overpayment relates to an excessive assessment rather than an excessive payment, and the excess is not due to a return error, the relevant chargeable period is the one to which the assessment relates.
• The claim must be made in the form prescribed by HMRC.
