CT600 Tax Return Filing in Longridge — Prepare and File Your Company Tax Return with HMRC

A CT600 is the form HMRC uses for a Company Tax Return. It is the formal document through which a company reports its Corporation Tax position for an accounting period, including figures such as turnover, trading profits, deductions and the calculation of any Corporation Tax due or any losses to carry forward. In practice, the CT600 is filed online and is usually accompanied by a Corporation Tax computation and a copy of the company's statutory accounts, which together explain how the reported figures were arrived at.

Generally, a UK company that is within the charge to Corporation Tax will need to file a Company Tax Return for each accounting period, and HMRC can also require a return to be filed in other circumstances, such as where a notice to deliver a return has been issued. Whether a specific company has a filing obligation depends on its own situation, and dormant or newly incorporated companies may have different requirements. If you are unsure whether a CT600 is needed for a particular period, it is worth checking your position rather than assuming.

Yes. Statutory accounts are prepared for the members and filed with Companies House under the applicable accounting framework, and they show the company's financial position and performance in accounting terms. The CT600 is a tax return filed with HMRC. The two are related because the accounts often provide the starting figures for the tax computation, but they are separate documents with separate filing obligations, separate recipients and separate purposes. Filing one does not automatically satisfy the other.

They are closely connected but not the same thing. The CT600 is the return itself — the structured set of boxes and disclosures submitted to HMRC. The Corporation Tax computation is the working paper that starts from accounting profit and sets out the adjustments needed to reach taxable profit, such as adding back disallowable expenditure, adjusting for non-taxable income and applying capital allowances, before applying the relevant tax treatment. The computation supports the figures entered on the CT600 and explains how the liability was calculated.

A micro-entity is defined by reference to the size thresholds that determine which accounting framework and disclosures a company can use when preparing its accounts, so the label does not create a separate or different tax return. If a micro-entity company is within the charge to Corporation Tax, or has been issued with a notice to deliver a return, it will generally need to file a Company Tax Return in the same way as other companies. That said, not every micro-entity will actually owe Corporation Tax — whether anything is payable depends on the company's taxable position, and the filing obligation and the payment obligation are separate matters.

These are two different requirements with two different recipients. A CT600 is submitted to HMRC, while statutory accounts are filed with Companies House, and each has its own obligations and timeframes. The tax return is normally supported by accounts and a computation, so in practice the two processes are usually prepared together even though they are filed separately. If you are unsure what needs to go where, and by when, it is best to check your company's position before submitting anything.

The company's accounting profit is the usual starting point, but it is not automatically the taxable profit. Adjustments may be required — for example, adding back expenditure that is not allowable for tax, deducting income that is not taxable, and claiming reliefs or allowances such as capital allowances on qualifying assets. Once these adjustments are made, the resulting taxable profit is used to determine the Corporation Tax position. Because the rules around what is allowable depend on the nature of the expense and the company's circumstances, the computation is often the part of the process that benefits most from professional review.

No. Filing a Company Tax Return and paying Corporation Tax are separate obligations with their own timescales. Submitting your CT600 tells HMRC what your company's position is; paying any Corporation Tax due is a distinct step and needs to be dealt with separately. A company might file a return showing no tax payable, or a loss to carry forward, and still have a filing obligation. Keeping good Corporation Tax records and diarising both the filing and any payment dates helps avoid muddles later.

If a Company Tax Return is filed after the deadline, HMRC may issue penalties and interest can be charged on unpaid tax, and the consequences can build the longer the return remains outstanding. The exact outcome depends on the circumstances, including whether any tax is outstanding and how late the filing is, so no two situations are identical. The practical answer is to file as early as you can and to tell HMRC promptly if you expect a delay. If you have missed a date, professional help with catching up and getting the return submitted can reduce the ongoing administration.
