Corporation tax self-assessment (CTSA): Claims and elections: Quantification

FA98/SCH18/PARA54 says that a company must quantify all claims it makes for:

  • a relief,
  • an allowance, or
  • a repayment of tax,

at the time it makes the claim.

“Quantified” means that the company must express the claim in figures. It is not acceptable to express the claim as a formula.

This rule does not apply to elections because most of them cannot be quantified immediately.
