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

CT600 Tax Return Filing is the process of preparing and submitting a company’s Company Tax Return to HMRC, reporting the company’s Corporation Tax position for an accounting period. For directors in Robertsbridge and the surrounding East Sussex area, professional support with CT600 Tax Return Filing can make the whole exercise far more straightforward: your accounting figures are reviewed, any tax adjustments are identified, the Corporation Tax computation is prepared, and the CT600 is completed and filed with HMRC on your company’s behalf. It is important to be clear that a CT600 is not the same thing as statutory accounts. Statutory accounts are prepared for the company’s members and filed separately with Companies House, while the CT600 is a tax return submitted to HMRC. The two are connected — the accounts usually provide the starting point for the tax calculation — but they serve different purposes, follow different rules, and are filed with different bodies. Our role is to bring accuracy and clarity to that process, so you know what is being reported, why the figures look the way they do, and when your filing obligations have been met.

 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 a CT600 Means for Micro-Entity Companies

There is no separate official ‘micro-entity CT600’. The CT600 is HMRC’s standard Company Tax Return form, and it is used by companies of all sizes — including those that meet the criteria to be treated as micro-entities for accounts purposes. A micro-entity company can still have Corporation Tax obligations, and where HMRC requires a Company Tax Return, that return is submitted as a CT600. What differs for a smaller company is usually the level of detail and the way the accounts are prepared, not the existence of a distinct form. It is also worth separating two things that are often confused. The statutory accounts a micro-entity prepares — potentially under a simplified accounting framework — are a separate filing obligation, generally filed with Companies House. The CT600 is a tax document filed with HMRC. The accounts and accounting records often form the starting point for the Corporation Tax calculation, but they do not determine the tax result on their own. Accounting profit and taxable profit can differ, because the Corporation Tax computation may require adjustments: items that are allowable for accounting purposes may be treated differently for tax, and reliefs or disallowances may need to be reflected. Filing the CT600 and paying any Corporation Tax due are also separate obligations — a return may be filed showing no tax payable, depending on the company’s circumstances and taxable position.

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

Let Us Handle Your CT600 Tax Return Filing in Robertsbridge

Preparing a Company Tax Return can quickly become complicated once you move from the accounts to the Corporation Tax computation.

Still unsure where you stand? Reach out to our UK team at info@microentityaccounts.co.uk and we will review your filing history with you.

What is a CT600?

A CT600 is the form HMRC uses for a Company Tax Return. It reports a company's Corporation Tax position for a given accounting period, including income, allowable deductions, reliefs claimed and the resulting Corporation Tax liability. The CT600 is filed with HMRC, not with Companies House, and it is the formal mechanism by which a company tells HMRC what its taxable position is for that period.

Is a CT600 the same as statutory accounts?

No. Statutory accounts are prepared for the company's members and are generally filed with Companies House, while a CT600 is a tax return submitted to HMRC. They overlap in that the accounts figures usually provide the starting point for the Corporation Tax calculation, but they are separate documents with separate purposes, separate audiences and separate filing obligations. A company can have both obligations, and completing one does not automatically satisfy the other.

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

It depends on the company's circumstances. Being a micro-entity affects how the statutory accounts may be prepared, but it does not by itself remove Corporation Tax obligations. Where HMRC requires a Company Tax Return, the company needs to complete and submit a CT600, and the form used is the same standard CT600 rather than a special micro-entity version. If you are unsure whether your company has been asked to file, we can review your position with you.

Is a CT600 different from a Corporation Tax computation?

Yes, and it is helpful to think of them as two connected stages. The Corporation Tax computation is the working document that starts from the accounting profit shown in the accounts and applies the necessary tax adjustments to arrive at taxable profit and the resulting Corporation Tax figure. The CT600 is the return that reports those outcomes to HMRC. You need the computation to complete the CT600 accurately, but they are not the same document.

How is taxable profit calculated from accounting profit?

The starting point is usually the profit shown in the company's accounts. From there, the Corporation Tax computation adjusts for items treated differently for tax purposes — for example, expenditure that is not allowable as a deduction, income that is treated differently, capital allowances in place of depreciation, and any reliefs the company is entitled to claim. The result is the taxable profit on which Corporation Tax is calculated. Because these adjustments depend on the specific transactions and circumstances of the company, the gap between accounting profit and taxable profit varies from business to business.

Is filing a CT600 the same as paying Corporation Tax?

No — filing and payment are separate obligations. Submitting the CT600 is about reporting the company's position to HMRC. Paying any Corporation Tax that is due is a distinct step, and a return may be filed showing no tax payable depending on the company's taxable position. Keeping the filing and the payment timetable clearly separated in your records helps avoid confusion.

What information is needed to prepare a CT600?

In broad terms, we need the company's accounting records and finalised accounts for the period, details of income and expenditure, information on any capital purchases that may attract allowances, records of any reliefs or losses being claimed or carried forward, and the company's registration details for HMRC. The exact list depends on the nature of the business. Where records are incomplete, part of the service is often helping to identify what is missing and how best to fill the gaps before the return is prepared.

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

Yes. Directors remain responsible for the accuracy of what is submitted, but it is common for an agent or accountant to prepare the CT600 and the supporting Corporation Tax computation and to file the return with HMRC on the company's behalf, once the director has reviewed and approved the figures. This is often the most practical route where the tax adjustments, allowances and reliefs involved need careful consideration, and it keeps the filing process moving without adding further pressure on the director's time.
