CT600 Tax Return Filing in Chapel-en-le-Firth – Prepare and File Your Company Tax Return with HMRC

The CT600 is the form HMRC uses for a Company Tax Return. It summarises a company's Corporation Tax position for an accounting period – the company's details, the period covered, the figures used to calculate taxable profit, the tax calculation itself, and any reliefs or claims being made. It is submitted online to HMRC, usually alongside a set of statutory accounts and a Corporation Tax computation. In short, the CT600 is the tax return, not a set of accounts and not a payment.

Whether a company needs to file a Company Tax Return depends on its circumstances. Broadly, a company that is within the scope of Corporation Tax and has been issued with a notice to deliver a return is expected to file one, and a return may also be required in other situations – for example where the company has taxable profits, has received certain income, or has been asked by HMRC to submit one. Small and micro companies are not automatically outside this: size affects the accounts you prepare, not whether HMRC can require a Company Tax Return. If you are unsure about your company's position, it is worth checking before the filing window passes.

Yes – they are two separate filings with two different purposes. Statutory accounts are prepared under company law and filed at Companies House, and they present the company's financial position and performance to shareholders and the public record. The CT600 is a tax return submitted to HMRC that reports the company's Corporation Tax position. The figures overlap because both start from the same accounting records, but they are not interchangeable documents, and filing one does not satisfy the requirement to file the other.

No, although they go hand in hand. The Corporation Tax computation is the working paper that starts with the company's accounting profit and makes the adjustments needed to arrive at taxable profit – removing disallowable expenditure, applying capital allowances, and dealing with any other tax-specific treatments. The CT600 is the return that reports the outcome of that calculation to HMRC, with the relevant figures entered in the appropriate boxes. A well-prepared CT600 is underpinned by a clear, properly documented computation.

There is no separate 'micro-entity CT600'. A micro-entity company uses the same CT600 as any other company if HMRC requires it to file a Company Tax Return. Choosing a micro-entity accounts framework such as FRS 105 affects how the statutory accounts are prepared – it does not by itself decide what Corporation Tax is payable, because the tax calculation is driven by tax rules rather than the accounting framework. Not every micro-entity will owe Corporation Tax, and that depends on the company's own taxable position.

Taxable profit usually starts from the profit shown in the accounts and is then adjusted. Common adjustments include adding back expenditure that is not allowable for tax purposes, deducting or claiming capital allowances instead of depreciation, and dealing with income or costs that are treated differently for tax than in the accounts. The result is the taxable profit on which any Corporation Tax liability is based. The exact adjustments depend on what the company has done during the period, which is why the computation is prepared alongside the CT600 rather than assumed from the accounts alone.

No – filing and payment are separate obligations. Submitting the CT600 tells HMRC what the company's Corporation Tax position is for the period. Paying any Corporation Tax that is due is a separate step, and the company may need to make payments before the return is filed depending on its circumstances. A company can have a CT600 filing requirement without having tax to pay, and a company with tax to pay still needs to file the return. Keeping records of both the filing and the payments is good practice.

Yes. A director can authorise an accountant or agent to prepare and submit the Company Tax Return through HMRC's online service, which is how most CT600 Tax Return Filing is handled in practice. To prepare it accurately, we typically need the company's year-end accounts or trial balance, the detailed breakdown of income and expenses, records of fixed asset purchases and disposals, details of any other income or claims, and confirmation of the accounting period and company details. If you are missing some of this, it is usually still worth starting the conversation, because the sooner the records are pulled together, the easier the filing becomes.

HMRC sets a deadline for delivering a Company Tax Return and expects it to be filed by that date. Filing late can result in penalties and can also affect the company's record with HMRC, and tax that is paid late can attract interest. The exact consequences depend on the company's circumstances and on HMRC's rules at the time, so we would always recommend checking your company's specific position rather than assuming. If you think a return may be late, telling us early gives the best chance of dealing with it in an orderly way.
