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

CT600 Tax Return Filing is the process of preparing your company’s Corporation Tax position and submitting the Company Tax Return (CT600) to HMRC. Our Radstock-based service is designed to make that process clear and manageable: we review your accounting records, work through the tax adjustments that turn accounting profit into taxable profit, and prepare the CT600 ready for submission. It is important to understand that the CT600 is a separate filing obligation from the statutory accounts you submit to Companies House, even though the two are prepared from the same underlying records. With professional support, you get a Company Tax Return that is accurate, consistent with your accounts, and submitted within HMRC’s requirements, without you having to learn the layout of the form or keep track of every adjustment yourself.

 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 Is a Micro-Entity CT600? CT600 Tax Return Filing Explained for Smaller Companies

There is no separate official form called a “micro-entity CT600”. The CT600 is HMRC’s standard Company Tax Return, and it is used by companies of all sizes, including those that qualify as micro-entities. Small and micro companies often have specific accounting considerations — such as the simplified disclosures available under the micro-entity regime — but those choices affect how the statutory accounts are prepared, not which Corporation Tax return is filed. If your company has Corporation Tax obligations and HMRC has requested a return, you will normally need to complete a Company Tax Return and submit it to HMRC. The accounting records and accounts you prepare are usually the starting point for the Corporation Tax computation, which is not the same document as the CT600 itself. Accounting profit and taxable profit can differ, because the Corporation Tax calculation may require adjustments — for example, disallowable expenditure or capital allowances. Filing the return and paying any Corporation Tax due are also separate obligations, and whether a company has a liability depends on its own circumstances and taxable position.

6 months late	HMRC estimates your tax bill and adds 10% of the unpaid tax

What is a CT600?

A CT600 is the form HMRC uses for a Company Tax Return. It sets out a company's Corporation Tax position for an accounting period, including figures drawn from the company's accounts and the calculation of taxable profit. The CT600 is submitted to HMRC, not to Companies House, and it is the document that reports the company's Corporation Tax position for that period. Most companies submit the return online, and the figures on it need to be supported by the company's records and computations.

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

Yes, they are two separate filings with two different bodies. Statutory accounts are prepared under an accounting framework and filed with Companies House, where they become part of the public record. The CT600 is a Company Tax Return submitted to HMRC and reports the company's Corporation Tax position. The two documents are usually prepared from the same underlying accounting records, but they serve different purposes: the accounts show the financial results, while the CT600 reports the tax position to HMRC. Filing one does not take the place of filing the other.

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

A micro-entity company may still have Corporation Tax obligations and, where HMRC requires a Company Tax Return, will need to submit a CT600. Being a micro-entity affects how the statutory accounts are prepared and the level of disclosure required, but it does not create a separate tax return. Whether the company actually owes Corporation Tax depends on its taxable position for the period, which is something the Corporation Tax computation will establish. Where a return is required, it still needs to be filed with HMRC even if no tax turns out to be payable.

Is a CT600 different from a Corporation Tax computation?

Yes. The Corporation Tax computation is the working paper that starts with the company's accounting profit and adjusts it to arrive at taxable profit — adding back disallowable items, deducting allowable reliefs, and so on. The CT600 is the return itself, which reports the results of that computation to HMRC in the required format. You need the computation to complete the return accurately, but they are distinct documents, and a well-prepared CT600 is always supported by a clear computation trail.

What information is needed to prepare a CT600?

Typically we need the company's accounting records for the period, a trial balance or final accounts, details of fixed asset additions and disposals, expense breakdowns so we can identify anything that may need adjusting, and any other income or reliefs relevant to the company. We also need the company's registration details and the accounting period being reported. If you already have previous returns or computations, those help us keep the treatment consistent from year to year. If anything is missing, we will tell you what is needed before we start.

Can a company file its CT600 without filing its accounts?

The two obligations are separate, so filing a Company Tax Return is not the same act as filing statutory accounts with Companies House. That said, the CT600 relies on the accounting figures, so the accounts normally need to be prepared — or at least substantially complete — before the return can be finalised. In practice, most companies prepare the accounts and the Corporation Tax computation together so the figures agree and the tax adjustments are properly documented. Leaving the accounts unfinished tends to create problems later rather than save time.

Is filing a CT600 the same as paying Corporation Tax?

No — filing and payment are separate obligations. Submitting the Company Tax Return tells HMRC what your company's Corporation Tax position is for the period. Paying any Corporation Tax that is due is a separate step, with its own deadlines. A company can file a return showing no tax payable, and equally a company can have tax to pay regardless of when the return is submitted. It is worth keeping both dates on your radar rather than assuming one triggers the other.

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

Yes. A company can appoint an accountant or agent to prepare the Company Tax Return, build the Corporation Tax computation, and submit the CT600 to HMRC on its behalf. The company remains responsible for the accuracy of the information provided and for any tax that is due, so the working relationship matters: you share the records, we handle the technical preparation and filing. If your records are incomplete or your circumstances have changed during the year, tell us early so the return reflects the real position.
