CT600 Tax Return Filing in Clanfield – Prepare and File Your Company Tax Return with HMRC

A CT600 is the Company Tax Return that a limited company submits to HMRC to report its Corporation Tax position for an accounting period. It sets out the company’s details, the accounting period covered by the return, and the figures that determine how much Corporation Tax, if any, is due. The return draws on the company’s accounts and on a Corporation Tax computation, which adjusts the accounting figures to arrive at taxable profit. The CT600 can also carry information about losses, reliefs and other matters that affect the company’s tax position, depending on the company’s circumstances.

A company generally needs to file a Company Tax Return where it is within the charge to Corporation Tax and HMRC requires a return for the period. In practice this includes most actively trading limited companies, but the position is not identical for every business: a dormant company, a company with no taxable activity, or one that has already told HMRC about its circumstances may have different obligations. Because the requirement depends on the company’s own situation rather than a single blanket rule, it is worth confirming your position for each accounting period before assuming a return is or is not needed.

Yes, they are separate filings with separate purposes. Statutory accounts are prepared for the company’s members and filed with Companies House, and they present the financial position and performance of the business under the applicable accounting framework. A CT600 is a tax return submitted to HMRC, and it reports the Corporation Tax position for the period. The accounts often provide the starting figures for the tax calculation, but filing a CT600 does not satisfy the Companies House filing obligation, and filing accounts at Companies House does not satisfy HMRC. Both need to be dealt with.

No. The Corporation Tax computation is the working that starts with the company’s accounting profit and adjusts it to reach taxable profit. Typical adjustments include adding back expenses that are not allowable for tax, removing income that is not taxable, replacing accounting depreciation with capital allowances, and bringing in losses or reliefs where they apply. The CT600 is the return itself, which reports the outcome of that computation to HMRC. In other words, the computation explains the numbers, and the CT600 delivers them.

A micro-entity company is not exempt simply because it prepares simpler accounts. There is no separate micro-entity version of the CT600 — the standard Company Tax Return is used. If the company is within the charge to Corporation Tax and HMRC requires a return, a CT600 will normally need to be filed. That said, whether Corporation Tax is actually payable depends on the company’s taxable position and its own circumstances; a micro-entity can have a Corporation Tax filing obligation without a tax liability. It is also worth remembering that the accounting framework used for the accounts does not by itself determine the tax outcome.

In broad terms, we need your accounting records and a set of figures for the accounting period, your company registration details and HMRC reference, the start and end dates of the period, and details of income and expenses. Information on capital purchases, asset disposals, losses brought forward, and any items that may need special tax treatment is also important, because these often drive the adjustments in the computation. The more complete and organised your records are, the more straightforward the preparation is — and if something is unclear or missing, we will tell you rather than guess.

No — filing and payment are separate obligations. Submitting the CT600 tells HMRC what your company’s Corporation Tax position is for the period. Payment of any Corporation Tax that is due is handled separately, and the timing of the payment obligation is not necessarily the same as the filing deadline. A company can file its return and still owe tax, or file a return showing no tax payable, depending on its taxable profit and the reliefs available to it. If tax is due, it is important to deal with the payment side as well as the return itself.

Yes. Many companies appoint an agent to prepare and submit their Company Tax Return, and HMRC allows authorised agents to file on a company’s behalf. We can act for your company, provided the necessary authorisation is in place, and handle the preparation of the computation, the completion of the CT600 and the submission to HMRC. You remain responsible for the accuracy of the information provided and for the company’s wider filing obligations, but the day-to-day work of putting the return together and getting it filed can sit with us.
