Taxation (International and Other Provisions) Act 2010 Schedule 7A paragraph 8

Revised interest restriction return

Paragraph 8 of Schedule 7A sets out when and how a reporting company may or must submit a revised interest restriction return for a period of account, including the time limits that apply.

• The reporting company may voluntarily submit a revised return within 36 months of the end of the period of account (or 3 months from appointment, if later)
• Where figures in a previous return have become incorrect, the reporting company must submit a revised return within 3 months of the relevant trigger date
• HMRC may extend the deadline for a compulsory revision where an enquiry into another group member's tax return may lead to a further revision being needed
• A revised return must show how it differs from the previous return and, once submitted, supersedes it
