Corporation Tax software that helps with the figures.
For supported UK micro-entity companies, add transactions yourself or provide financial records, such as a bank statement, spreadsheet or document. On the Guided route, Simple Returns prepares your Company Tax Return and FRS 105 accounts. You check every figure before it files to HMRC and Companies House for £99.
HMRC tells us whether your company is ready only after you authenticate. If it cannot authenticate, HMRC does not tell us whether the UTR, sign-in or Corporation Tax setup caused it. Nothing is sent until you check and approve the figures.
If Corporation Tax is not switched on for your company yet, our guide on activating Corporation Tax online walks through it.
What a Company Tax Return has to contain.
HMRC asks a limited company for three things together: the CT600, a computation, and the accounts. The computation is the working that turns the profit in your accounts into the figure Corporation Tax is charged on. The accounts and the computation have to be in iXBRL, a format that tags each figure so HMRC can read it. The CT600 is the form they attach to, and is not itself iXBRL.
Companies House wants the accounts too, which is why the same year gets filed to two places.

What the software does.
It does the accountancy
Upload a bank statement (CSV, PDF, spreadsheet or a photo), or type your transactions in, and the software sorts every one into the 16 categories your accounts are built from, builds your accounts, and calculates the Corporation Tax. No chart of accounts to set up.
Built only for micro-entities
Not a general ledger package bent into shape for general small-business bookkeeping. It does one job: the annual Corporation Tax return and FRS 105 accounts a UK micro-entity director files once a year.
Files to HMRC and Companies House
Submits your CT600 to HMRC and your iXBRL accounts to Companies House in a single step, and returns a confirmation reference from each. The Guided fee is £99, paid at checkout before Final Review and sign-off.
Corporation Tax software questions.
What is Corporation Tax software?
It is software that prepares and files a limited company's Corporation Tax return (the CT600) and statutory accounts. Simple Returns is built for UK micro-entities: it categorises your transactions, prepares FRS 105 accounts, calculates the tax, and files to HMRC and Companies House.
Do I need accounting knowledge to use it?
No. The software does the categorisation and the tax calculation. Everything is shown in plain English, line by line, and you check the figures before anything is submitted. There is no accounting jargon to learn.
Who is it for?
UK limited companies that qualify as micro-entities: broadly, meeting at least two of a turnover of £1 million or less, a balance sheet total of £500,000 or less, and 10 or fewer employees. Contractors, single-director companies and dormant companies are all common.
Do I need an accountant?
Not for a return within our supported scope. Simple Returns is self-service software: it helps form the figures, prepares the return and accounts, and shows them to you for checking. If your company falls outside that scope, you will need an accountant or another suitable service.
Do I need completed accounts first?
No. Completed figures are not required to begin. You can add transactions yourself or provide financial records, such as a bank statement, spreadsheet or document, and Simple Returns forms the figures from them. You check and approve every one before anything is sent.
Can I file a CT600 myself?
Yes, if your company is within our supported scope. Simple Returns gives directors a self-service route: the software forms the figures and prepares the CT600 and accounts for you to check before submission.
Is it free to start?
Yes. You can link your company, add transactions or records, and check the figures without paying. You decide whether to continue to checkout only after the figures have been prepared.
When do I pay?
At checkout, after your figures have been prepared and before Final Review and sign-off. The Guided filing fee is £99, with no subscription or per-user price. Nothing is submitted until you sign off.
Does it file the accounts to Companies House too?
Yes. Your CT600 goes to HMRC and your iXBRL micro-entity accounts go to Companies House in the same step, so you do not have to file the two separately.
