CT600E guide

CT600E: charity and CASC exemption claims in the Corporation Tax return.

A practical guide for charities, Community Amateur Sports Clubs, and advisers preparing CT600E supplementary pages for exemption claims, income, gains, and repayments.

What CT600E is for

CT600E is the HMRC supplementary page for charities and Community Amateur Sports Clubs, usually called CASCs, where the organisation claims exemption from Corporation Tax on all or part of its income and gains.

HMRC explains that the supplementary pages form the charity's or CASC's claim to exemption where income and gains have been applied for charitable or qualifying purposes only. That means CT600E is not just background information. It is part of the claim made with the Company Tax Return.

When CT600E may be needed

CT600E is relevant where the organisation is within Corporation Tax filing and needs to claim exemption for charity or CASC purposes. The trigger is the claim to exemption, not simply the fact that the organisation is charitable or sporting.

  • A charity or CASC is filing a Company Tax Return.
  • The organisation claims exemption from tax on all or part of its income or gains.
  • The claim is based on the income and gains being applied for charitable or qualifying purposes.
  • Repayment or bank details are needed for a repayment case.
  • The main CT600 needs to indicate that CT600E forms part of the return.

What the reviewer needs to check

Charity and CASC CT600 work often looks simple until the exemption claim, repayment detail, and underlying use of funds need to be evidenced. A structured review should make those points explicit.

  • Charity or CASC identity and registration details where relevant.
  • The accounting period covered by CT600E.
  • The income and gains for which exemption is being claimed.
  • Whether the funds have been applied for charitable or qualifying purposes.
  • Any repayment reference, nominee, or bank detail needed for HMRC processing.
  • The link between the CT600E claim and the main CT600 figures.

Common CT600E workflow traps

The first trap is assuming that charity status alone completes the Corporation Tax analysis. CT600E still needs a clear claim and supporting facts. The second is separating repayment administration from the tax review, which can lead to incomplete or mismatched filing data.

The third trap is treating CT600E as a form-filling exercise after the return has already been reviewed. Because the supplementary pages form part of the claim, the review should happen before the return is signed off, with the same discipline as the main CT600 and iXBRL attachments.

How Robocount handles CT600E workflow

Robocount keeps CT600E in the main Corporation Tax filing workflow so charity and CASC claim details can be reviewed with the return instead of being buried in a detached note.

  • Captures charity and CASC claim indicators.
  • Tracks exemption, repayment, and reference details for review.
  • Keeps CT600E visible alongside the main CT600 figures.
  • Connects supplementary-page inclusion to the filing pack review.
  • Gives practices a clearer trail for claim decisions and client sign-off.

Review checklist before filing

  • Confirm the entity is a charity or CASC for the period being filed.
  • Confirm whether CT600E is required for the exemption claim being made.
  • Review income and gain categories against the charitable or qualifying-purpose analysis.
  • Check repayment details before submission if money is due back from HMRC.
  • Make sure the main CT600 and CT600E package agree.

FAQ

Does every charity need to file CT600E?

Not necessarily. CT600E is used where a charity or CASC is filing a Company Tax Return and claiming exemption on all or part of its income and gains. Filing requirements depend on the organisation's circumstances and HMRC position.

Is CT600E only for registered charities?

CT600E covers charities and Community Amateur Sports Clubs. The right treatment depends on the organisation's status, activities, income, gains, and claim basis for the accounting period.

Why does CT600E matter if no tax is due?

A no-tax position still needs to be claimed and evidenced where HMRC has asked for a Company Tax Return or the organisation is filing one. CT600E helps carry that exemption claim in the return package.
