Taxes Management Act 1970 section 10

Notice of liability to corporation tax

Section 10 requires a company that is liable to corporation tax to notify HMRC of that liability within a specified time if it has not already received a notice to file a return.

• A company chargeable to corporation tax for an accounting period must notify HMRC of its chargeability if it has not received a notice to deliver a corporation tax return.
• The notification must be made within twelve months of the end of the accounting period in question.
• This obligation ensures that HMRC is made aware of a company's tax liability even where HMRC has not already identified the company and issued a return notice.
• The requirement was introduced by Finance Act 1998 as part of the move to corporation tax self-assessment, placing the onus on companies to come forward rather than waiting for HMRC to act.
