CTM92550 | CTSA: quarterly instalments: identification of large companies

From HM Revenue & Customs · Company Taxation Manual

Companies are expected to:

  • decide for themselves if they need to make quarterly instalment payments (QIPs),

and

  • take the initiative to make instalment payments.

Companies must indicate on the return form (CT600) if they are a large or very large QIP case. See for further information on the ‘QIP’ signal and the , business area ‘Pursuit’ for fuller details.

The computer issues payslips to companies when the ‘QIP’ signal on the company record is ‘potential’, ‘L’ or ‘V’. It issues these about a month before the likely due date for an instalment payment they may need to make.

This is a non-statutory assistance measure and does not affect the principle that the Regulations require the company to act without prior prompting.
