A Corporation Tax Return is the formal report a company sends to HMRC to report its taxable profit or loss for an accounting period and work out how much Corporation Tax is due, if any. In most cases this is done through a CT600, which is the HMRC form used to submit the return online. Preparing a return normally involves looking at the company's financial information, considering the accounting profit or loss, identifying any tax adjustments required by Corporation Tax rules, and arriving at the taxable profit figure before the return is submitted.
The CT600 is the Company Tax Return form issued by HMRC. It is not a Companies House document and it is not filed with Companies House. Alongside the form itself, a return usually includes the company's statutory accounts and a tax computation, depending on the company's circumstances and the applicable requirements. Once complete, the CT600 is submitted to HMRC electronically.
No. There is no separate micro-entity CT600. A micro company deals with Corporation Tax through the same Corporation Tax Return process as any other company, subject to its own circumstances. Micro-entity status relates to the accounting framework a company may use when preparing its accounts, and eligibility depends on the applicable criteria, the accounting period and the company's individual position. It does not create a separate Corporation Tax regime or a different return form.
The starting point is usually the company's financial information for the period, which may include bookkeeping records, bank transactions, invoices and expense records. From there, the accounting profit or loss is reviewed and any relevant tax adjustments are considered, since Corporation Tax rules can treat certain items differently from the way they appear in the accounts. The taxable profit is then determined and the Corporation Tax Return prepared for submission to HMRC. The exact work involved varies depending on the company's circumstances.
They are two separate documents with two different purposes and two different destinations. Statutory accounts are prepared under the applicable accounting framework and delivered to Companies House where required. A Corporation Tax Return, such as a CT600, is submitted to HMRC and deals with the company's tax position. Preparing or filing a CT600 does not automatically complete the company's Companies House accounts, confirmation statement or any other filing obligation, and the two should not be treated as interchangeable.
Accounting profit is worked out using accounting standards, while taxable profit is worked out using Corporation Tax rules. Those rules can require adjustments, for example where certain costs are treated differently for tax purposes or where income is recognised at a different point. This is why directors sometimes see a profit figure in the accounts that does not match the taxable profit used for the return. The adjustments needed depend entirely on the company's own transactions and circumstances.
Not necessarily. The deadline for submitting a Corporation Tax Return to HMRC and the deadline for paying any Corporation Tax that is due can fall on different dates, so it is worth checking both rather than assuming they align. Missing either one can lead to interest or penalties, so directors should keep both dates in view. If you are unsure which dates apply to your company, professional advice can help clarify the position.
Dormant for Corporation Tax purposes is not the same as dormant for Companies House purposes, and the two are assessed separately. A company that HMRC treats as dormant may still have some reporting requirements, and a company that is dormant at Companies House may not be dormant for tax. Dormant status does not automatically remove all Companies House filing obligations, and it does not mean a company must keep submitting Corporation Tax Returns indefinitely either. The position depends on the company's specific circumstances, and it is worth confirming before assuming no return is needed.
