CT600 Tax Return Filing in Thornton-Cleveleys: Prepare and File Your Company Tax Return with HMRC

CT600 Tax Return Filing is how a UK company reports its Corporation Tax position to HMRC, and getting it right matters. Our service in Thornton-Cleveleys helps limited companies pull together the figures from their accounting records, review the tax adjustments that turn accounting profit into taxable profit, and submit an accurate Company Tax Return through HMRC’s online system. It is important to understand that a CT600 is not the same thing as the statutory accounts filed with Companies House, and it is not a Confirmation Statement or a VAT Return — each is a separate filing with a separate purpose. Statutory accounts present your company’s financial position for the year, while the CT600 reports the Corporation Tax due on your taxable profits, which may differ from the profit shown in your accounts. Professional support means fewer last-minute panics, a clear view of what is being reported and why, and the convenience of having the preparation and submission handled for you. We work with directors across Thornton-Cleveleys and the surrounding area who want their Corporation Tax reporting done properly, with clear, transparent pricing and practical guidance at every stage.

 Trustindex verifies that the original source of the review is Google. I worked with Accotx on a HMRC reclaim and overall, they did ultimately deliver on their promise, which I appreciate. The process did take longer than any of us expected, partly due to external delays with the tax authorities, and partly because there were some hiccups in communication and follow-up. However, despite those challenges, they stayed professional and stuck to the original agreed terms. If you’re considering using them, be prepared to stay in regular contact to keep things moving along. They are absolutely capable, have the expertise and willing to work with you, and overall  improving their services over time. I would certainly return for any future needs.

He helped me sort out a very complicated backlog of accounts and prepared my overdue tax returns with professionalism and attention to detail.

Throughout the process, he was incredibly patient, took the time to answer all of my questions, and explained everything clearly. He guided me through each step and helped rectify issues that had built up over time, making what felt like an overwhelming situation much more manageable.

What Does CT600 Tax Return Filing Mean for a Micro-Entity Company?

There is no separate HMRC form called a ‘micro-entity CT600’. The CT600 is the standard Company Tax Return used by UK companies, and it applies to micro-entity companies in exactly the same way as it applies to larger ones — the size of the company affects how the accounts are prepared, not which tax return is submitted. A company that qualifies as a micro-entity may still have Corporation Tax obligations and, where HMRC requires a return, will need to submit a Company Tax Return reporting its Corporation Tax position. The accounting framework a company uses to prepare its accounts, such as FRS 105, does not by itself determine the Corporation Tax liability; it simply sets out how the accounts are drawn up. The CT600 is also separate from the statutory accounts filed with Companies House, and separate again from a Confirmation Statement or a VAT Return. When it comes to the tax calculation, the accounting records and accounts are usually the starting point, but the taxable profit can differ from the accounting profit because Corporation Tax calculations may require adjustments — for example to add back disallowable expenditure or to account for capital allowances and other reliefs where they are available. Not every micro-entity will owe Corporation Tax; whether anything is payable depends on the company’s own circumstances and taxable position for the period. It is also worth remembering that filing the CT600 and paying any Corporation Tax due are two separate obligations — submitting the return on time does not settle the tax, and paying the tax does not complete the filing.

What is a CT600?

A CT600 is the name of the form HMRC uses for a Company Tax Return. It is the formal way a UK company reports its Corporation Tax position for an accounting period — setting out the company's income, the profits that are chargeable to Corporation Tax, and the Corporation Tax that is due. In most cases the return is submitted to HMRC online, and the figures reported are supported by a Corporation Tax computation and, where required, a copy of the statutory accounts.

Who needs to file a CT600?

A company is normally required to file a Company Tax Return if HMRC has issued a notice to deliver one, or if the company has a Corporation Tax liability for the period. That can include trading companies, dormant companies in certain circumstances, and companies with no tax to pay. Whether a specific company needs to file, and for which periods, depends on its own circumstances, so it is worth checking your position rather than assuming it either applies or does not.

Is a CT600 different from the statutory accounts filed with Companies House?

Yes — they are two separate documents with two different purposes and two different recipients. Statutory accounts are filed with Companies House and present the company's financial performance and position, prepared under an applicable accounting framework. A CT600 is filed with HMRC and reports the company's Corporation Tax position. The figures used to prepare the accounts are usually a starting point for the tax return, but they are not the same thing, and one filing does not satisfy the other.

Is a CT600 different from a Corporation Tax computation?

They are related but not the same. The Corporation Tax computation is the working paper that starts with the accounting profit from the accounts and then makes the adjustments needed to arrive at the taxable profit and the resulting Corporation Tax liability. The CT600 is the actual return submitted to HMRC, and it relies on the figures produced by that computation. In practice the computation sits behind the return and explains how the numbers were arrived at.

Does a micro-entity company need to file a CT600?

A micro-entity company follows the same Company Tax Return rules as any other company. Qualifying as a micro-entity affects how the accounts are prepared, not which tax return applies, and there is no separate 'micro-entity CT600' form. Whether a particular micro-entity company needs to file a CT600, and for which periods, depends on its circumstances and whether HMRC has issued a notice to deliver a return or the company has a Corporation Tax liability.

How is taxable profit calculated from accounting profit?

The starting point is normally the profit shown in the company's accounts, but taxable profit is not automatically the same figure. The Corporation Tax computation may require adjustments — for example adding back expenditure that is not allowable for tax purposes, deducting items that are treated differently for tax, and accounting for capital allowances and any other reliefs the company is entitled to claim. The result is the taxable profit on which Corporation Tax is calculated, and it can be higher or lower than the accounting profit.

Is filing a CT600 the same as paying Corporation Tax?

No — filing and payment are separate obligations. Submitting the CT600 tells HMRC what the company's Corporation Tax position is for the period; paying Corporation Tax is a separate step that settles the liability. A company can file its return and still have tax to pay, or file a return showing no tax due. Both the filing and any payment need to be dealt with, and each has its own timetable set by HMRC.

Can someone prepare and file a CT600 on behalf of a company?

Yes. A director, company secretary or another authorised person can prepare and submit a Company Tax Return on the company's behalf, and many companies ask an accountant to handle it. Doing so is not just about the mechanics of submission — it also means having someone review the accounting figures, consider the tax adjustments, prepare the Corporation Tax computation and make sure the information reported to HMRC is complete and consistent with the company's records.
