Corporation tax
A return HMRC accepts, computed from your own ledger.
Filing corporation tax online means sending three documents together, in formats that have to satisfy a validator before a human ever sees them. Stewardry produces all three.
What gets sent
Three documents, one submission.
- The CT600
- The return itself: turnover, trading profit, chargeable profits, the tax charge and any marginal relief, in the boxes HMRC expects them.
- The computations
- The working that gets from the profit in your accounts to the profit charged to tax — every add-back and allowance shown, tagged in iXBRL.
- The accounts
- Statutory accounts under FRS 105, with the balance sheet statements the Companies Act requires above the signature. Also iXBRL.
What you do not have to think about
The awkward parts are the software's problem.
Corporation tax filing is not a form you post. The submission is signed XML over HMRC's Government Gateway, and the accounts and computations have to be tagged in inline XBRL against taxonomies HMRC revises every year. Get a tag wrong and it is refused. Get it subtly wrong and it is accepted while saying something you did not mean.
None of that reaches you. What you see is your figures, the working behind them, and a receipt from HMRC when it lands.
Before you can file
Recognition, and why it matters.
HMRC publish a list of software they accept corporation tax returns from. Recognition means passing their test scenarios, and it is renewed every year. It is worth checking for any product you are considering — including this one.
Stewardry's recognition is in progress. We will open filing to customers once we are listed, and say so here when we are. In the meantime we are working with a small number of companies preparing for their first return.
