iXBRL tagging for charities & charitable companies
Charitable companies file with Companies House like any other company — and when HMRC requires a return, the CT600E supplementary page and SORP-compliant accounts add tagging complexity most general services handle rarely. We handle it routinely.
Charity accounts aren't standard company accounts
A charitable company's obligations span Companies House, the Charity Commission, and — when a notice to file is issued — HMRC. Each expects different things from the same underlying accounts.
Charities SORP accounts
Accounts prepared under the Charities SORP (FRS 102) include fund accounting, restricted and unrestricted funds, and a trustees' annual report — structures standard company taxonomies weren't designed around.
CT600E supplementary page
When HMRC requires a return, charities claiming exemption complete the CT600E alongside the core CT600 — a supplementary page that needs correct tagging most filers rarely encounter.
Trading subsidiaries
Many charities run a trading subsidiary that files as a normal company, gift-aids its profits, and needs standard full tagging — two related but different filings to keep straight.
Both sides of a charity's filing, tagged correctly
Whether it's the charitable company's own SORP accounts for Companies House, a CT600 with CT600E for HMRC, or the trading subsidiary's standard return, we map each document to the correct taxonomy elements and validate before delivery.
- Charities SORP (FRS 102) accounts tagged for Companies House filing
- CT600 with CT600E supplementary page for HMRC returns
- Trading subsidiary accounts and computations handled alongside

Every charity filing gets our standard independent second review before it reaches you or your trustees.
Frequently asked questions
Does a charitable company need to file a CT600?
Only if HMRC has issued a notice to deliver a return — many charities have exempt income and no notice is issued, but where one is issued, the CT600E supplementary page claims the relevant exemptions alongside the core return.
Do we need to tag our trustees' annual report?
The trustees' annual report is a narrative document filed alongside the accounts; the figures within the SORP-compliant accounts themselves are what need iXBRL tagging for Companies House.
Our charity has a trading subsidiary — is that a separate filing?
Yes — a trading subsidiary is a standard company in its own right, filing its own Companies House accounts and CT600, tagged like any other company, separately from the charity's own filing.
