CT600 Tax Return Filing in Folkestone: Prepare and File Your Company Tax Return with HMRC

Every UK company that needs to report its Corporation Tax position has to submit a Company Tax Return — known as a CT600 — to HMRC. Our CT600 Tax Return Filing service in Folkestone is built to take the uncertainty out of that process, whether you are a sole director running a small trading company or an established business with several shareholders. We work through your accounting records and statutory accounts, review the figures that feed into the return, and help you understand where adjustments may be needed before taxable profit and any Corporation Tax liability are determined. It is important to be clear about what a CT600 is and is not: it is a tax return submitted to HMRC, and it is entirely separate from the statutory accounts that a company files with Companies House, and from the Confirmation Statement, VAT Returns and other company filing obligations. Accounts preparation and Corporation Tax filing are related but distinct processes, and getting the Corporation Tax side right means thinking carefully about the tax treatment of income, expenses and allowances rather than simply copying the accounting profit across. Our role is to help you prepare the figures accurately, explain the reasoning behind them in plain English, and submit the Company Tax Return to HMRC on your behalf, so you can spend your time running the business instead of wrestling with paperwork.

 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 and How Does It Affect Small Companies?

You will sometimes hear the phrase ‘micro-entity CT600’, but it is worth being precise: there is no separate official micro-entity version of the CT600. The CT600 is simply the name of the Company Tax Return that companies use to report their Corporation Tax position to HMRC, and it is the same core return regardless of a company’s size or the accounting framework it applies. Where micro-entities come into the picture is on the accounts side. A company that qualifies as a micro-entity may prepare and file simpler statutory accounts, often under the FRS 105 framework, and those accounts are then filed separately with Companies House. Running a micro-entity company does not automatically remove Corporation Tax obligations. If HMRC has issued a notice to file a Company Tax Return, the company is expected to complete and submit a CT600, and the figures in the company’s accounting records and statutory accounts are typically the starting point for that work. The important point to understand is that the accounting framework used to prepare the accounts does not, by itself, determine the Corporation Tax liability. The CT600 is based on the company’s taxable profit, which can differ from the accounting profit shown in the accounts because the Corporation Tax computation may require adjustments — for example, adding back disallowable expenses or claiming reliefs and allowances that are not reflected in the accounts. A micro-entity can also have a Corporation Tax position that results in no tax being payable, depending on its circumstances and taxable position, and filing the CT600 is a separate obligation from actually paying any Corporation Tax that is due. Most companies will need professional support to work through these adjustments sensibly, which is where a focused CT600 Tax Return Filing service in Folkestone can help.

What is a CT600?

A CT600 is the format HMRC uses for a Company Tax Return. It is the return a company submits to HMRC to report its Corporation Tax position for an accounting period, setting out figures such as turnover, trading profits, allowable deductions and any tax payable or repayable. The CT600 is a tax document, not an accounts document — it is submitted to HMRC, whereas statutory accounts are filed separately with Companies House.

Who needs to file a CT600 Tax Return?

Broadly speaking, a company needs to file a Company Tax Return if HMRC has issued it with a notice to file. Being a small or micro-entity company does not automatically take you outside that obligation. Whether a particular company is required to file for a given period, and what it needs to report, depends on its own circumstances, so it is worth checking your position rather than assuming either way. Directors in Folkestone and elsewhere can ask HMRC directly or take advice on their specific situation.

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

Yes, and this is one of the most common sources of confusion. Statutory accounts are prepared under an accounting framework and filed with Companies House as a public record of the company's financial position and performance. The CT600 is a Corporation Tax return submitted to HMRC. The two are separate filings with separate recipients, separate purposes and separate submission processes, even though they draw on the same underlying bookkeeping and often need to be prepared alongside each other. Accounts preparation and Corporation Tax filing are related processes, but they are not the same thing.

Is a CT600 the same as a Corporation Tax computation?

No. The Corporation Tax computation is the working document that starts with the company's accounting profit and makes the tax adjustments needed to arrive at taxable profit — for example, adding back expenses that are not allowable for tax and deducting items that are treated differently for tax purposes. The CT600 is the return form itself, which reports the resulting figures to HMRC. You need the computation to complete the return accurately, but the computation is a supporting calculation rather than the submission.

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

There is no separate 'micro-entity CT600' form. The CT600 is the standard Company Tax Return used by companies generally, and a micro-entity company may still need to file one where HMRC has issued a notice to file. Operating as a micro-entity affects the accounts you prepare and file at Companies House, but it does not by itself settle your Corporation Tax obligations. Equally, not every micro-entity will owe Corporation Tax — whether tax is payable depends on the company's circumstances and its taxable position for the period.

What information is needed to prepare a CT600?

Preparation normally starts with the company's accounting records for the accounting period, the draft or finalised statutory accounts, and details of anything that needs specific tax treatment, such as capital purchases, disallowable expenses, trading losses brought forward, or income taxed under a different set of rules. It also helps to have your company registration details, your Unique Taxpayer Reference, and any previous returns or correspondence from HMRC to hand. The more organised your records, the more straightforward the CT600 Tax Return Filing process tends to be, and the easier it is to explain the figures behind the return.

How is taxable profit calculated from accounting profit?

Accounting profit is the figure shown in your accounts after applying accounting standards. Taxable profit is what the Corporation Tax rules are applied to, and the two can be different. The Corporation Tax computation starts with the accounting profit and then makes adjustments: adding back expenditure that is not deductible for tax, removing income that is not taxable in the normal way, and reflecting reliefs or allowances that are claimed for tax but not recognised in the accounts. Only once those adjustments are made can the taxable profit and any resulting Corporation Tax liability be established.

Is filing a CT600 the same as paying Corporation Tax?

No — these are two separate obligations. Filing the CT600 is about reporting the company's Corporation Tax position to HMRC, while paying Corporation Tax is about settling the liability that the return shows as due. A company can have filed its return and still owe a payment, or it can file a return that shows no tax payable for that period. Corporation Tax payment deadlines also run independently of the filing deadline, so it is worth keeping both in view rather than assuming one takes care of the other.
