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

A CT600 is the form used to submit a Company Tax Return to HMRC. It sets out the company's Corporation Tax position for an accounting period, including the company's income, allowable deductions, reliefs and allowances, and the resulting tax calculation. The CT600 is a tax filing rather than a set of accounts, and it is submitted to HMRC rather than to Companies House. In practice, the CT600 figures are usually supported by a Corporation Tax computation and by the company's accounts and accounting records.

A Company Tax Return is the formal return a company sends to HMRC to report its Corporation Tax position for an accounting period. The CT600 form is the main part of that return, and it is normally supported by a copy of the statutory accounts and a Corporation Tax computation. A Company Tax Return is not the same as statutory accounts, which are filed at Companies House, and it is not the same as a Confirmation Statement or a VAT Return. Each of these is a distinct filing with its own purpose.

A company generally needs to file a Company Tax Return when HMRC has issued a notice to deliver one, or where the company is within the charge to Corporation Tax for the period. If you have started a new company, began trading, or become liable to Corporation Tax, it is worth checking what HMRC expects from you, as the position depends on the company's circumstances. A dormant or non-trading company may have different obligations, and in some cases no return is due at all. Where a return is required, CT600 Tax Return Filing should be treated as a separate task from filing accounts at Companies House.

Yes — they are two separate filings with two separate audiences. Statutory accounts are prepared for the company's members and filed with Companies House, and they present the company's financial position and performance in line with the applicable accounting framework. The CT600 is a Company Tax Return submitted to HMRC, and it reports the company's Corporation Tax position. Although both are based on the same underlying bookkeeping and accounting records, the figures can differ because the Corporation Tax computation may require adjustments to the accounting profit.

They are related but not the same thing. The Corporation Tax computation is the working paper that starts with the accounting profit shown in the accounts, makes the tax adjustments needed — for example adding back disallowable expenditure or deducting allowable items and reliefs — and arrives at the taxable profit and the resulting Corporation Tax. The CT600 is the form on which those results are reported to HMRC. Preparing a clear computation is one of the most useful parts of CT600 Tax Return Filing, because it shows how the return figures were reached and provides a record if HMRC asks questions later.

There is no separate micro-entity CT600 form — a micro-entity uses the same CT600 as any other company. Whether a particular micro-entity company needs to file a Company Tax Return depends on its own circumstances, including whether HMRC has issued a notice to deliver a return and whether the company is within the charge to Corporation Tax. Being a micro-entity for accounts purposes does not by itself remove Corporation Tax filing obligations, and it does not by itself create a Corporation Tax liability. If you are unsure where your company stands, it is worth getting the position checked before the filing date.

Yes. A company can appoint an accountant or tax agent to prepare the Company Tax Return and submit it to HMRC on the company's behalf, and HMRC can be authorised to deal with that agent directly. The company remains responsible for the accuracy of the return and for making sure it is filed, but the day-to-day work — gathering the figures, preparing the Corporation Tax computation, reviewing tax adjustments and submitting the CT600 — can be handled for you. This is what most businesses mean when they look for professional CT600 Tax Return Filing support.

No — filing and payment are separate obligations. Submitting the Company Tax Return tells HMRC how the company's Corporation Tax position has been calculated, but it does not itself pay the tax. Where a liability arises, the company still needs to make payment separately by the relevant payment date, and the amount due may be affected by any payments already made or by the company's circumstances. It is also possible for a company to have a filing obligation while having no Corporation Tax to pay for that period, depending on its taxable position.

Most CT600 preparation starts with the company's accounting records and a set of accounts for the period, along with details of income, expenses, capital purchases, any reliefs or allowances being claimed, and any earlier periods that could affect the current calculation, such as losses carried forward. Your accountant will also want to understand the company's activities so that the right tax treatment is applied. The exact information required varies from company to company, which is why a short review of your records before the return is prepared usually saves time later.

If a Company Tax Return is filed after the date HMRC expects it, HMRC can apply penalties and may charge interest on any tax paid late. The exact position depends on how late the return is and on the company's circumstances, so it is best to deal with a late or at-risk filing as soon as possible rather than leaving it. Filing earlier in the process gives you more time to check the figures, resolve queries, and correct anything that looks wrong before submission.
