CT600 Tax Return Filing in Wallington – Prepare and File Your Company Tax Return with HMRC

CT600 Tax Return Filing is the process of preparing a company’s Corporation Tax position and submitting its Company Tax Return to HMRC. For directors in Wallington, professional support with CT600 Tax Return Filing means the accounting figures behind the return are reviewed carefully, the tax adjustments needed to move from accounting profit to taxable profit are considered properly, and the completed CT600 is filed with HMRC accurately and on time. It is important to understand that a CT600 is not the same as the statutory accounts filed with Companies House. Statutory accounts are a separate filing obligation prepared under an applicable accounting framework, while the CT600 is the document that reports the company’s Corporation Tax position to HMRC. The figures used for Corporation Tax are usually based on those accounts, but they often need adjusting — for example to add back disallowable expenses or to account for capital allowances and other reliefs — before the taxable profit and any Corporation Tax liability can be worked out. Working with an experienced team takes the guesswork out of that process, keeps your records organised, and gives you clear, transparent pricing without the need to interpret HMRC guidance alone.

 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 Fit with Company Tax Return Filing?

There is no separate official “micro-entity CT600” form. A CT600 is simply the Company Tax Return that a UK company submits to HMRC to report its Corporation Tax position, and it applies to companies of all sizes — including those that qualify as micro-entities. A micro-entity is a company that meets certain size criteria and may therefore prepare its statutory accounts under a simplified accounting framework, but that status does not remove the company’s Corporation Tax obligations. If a company has a Corporation Tax liability, has received a notice to file from HMRC, or has taxable income or profits to report, it will generally need to submit a Company Tax Return (CT600) to HMRC, and CT600 Tax Return Filing should be treated as a distinct task from preparing and filing statutory accounts with Companies House. The company’s accounting records and accounts usually form the starting point for the Corporation Tax calculation, but the accounting profit shown in those accounts is not automatically the same as the taxable profit. Corporation Tax calculations commonly involve adjustments — such as adding back expenses that are not allowable for tax, deducting capital allowances, or accounting for other reliefs and adjustments — and the resulting taxable profit may differ from the accounting profit. That is why accounts preparation and Corporation Tax filing are related but separate processes. Where a micro-entity company’s circumstances mean no Corporation Tax is payable, a return may still be required depending on the company’s position and any notice received from HMRC. It is also worth remembering that filing the CT600 and paying any Corporation Tax due are separate obligations: submitting the return does not itself settle the tax, and payment arrangements should be handled separately.

What is a CT600?

A CT600 is the official form used to submit a Company Tax Return to HMRC. It reports a company's Corporation Tax position for an accounting period, setting out figures such as turnover, trading profits, allowable deductions and the resulting taxable profit, along with the Corporation Tax charge that follows from those figures. In practice the term CT600 is often used to describe the whole exercise of preparing the Company Tax Return, including the underlying Corporation Tax computation that supports the numbers entered on the form.

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

Yes, they are two separate documents with two separate purposes and two separate recipients. Statutory accounts are prepared under an applicable accounting framework and filed with Companies House as part of the public record, while a CT600 is a Company Tax Return submitted to HMRC to report the company's Corporation Tax position. Because they serve different purposes, the way figures are presented can differ, and the accounts figures normally need to be adjusted before they can be used to calculate taxable profit.

Who needs to file a CT600 Tax Return with HMRC?

A company generally needs to submit a Company Tax Return if HMRC has issued a notice to file, or if the company has taxable profits, income or gains to report for an accounting period. The exact position depends on the company's own circumstances, including whether it has been active, whether it has traded, and whether HMRC has formally requested a return. If you are unsure whether your company needs to complete CT600 Tax Return Filing for a particular period, it is worth taking advice rather than assuming a return is or is not required.

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

Possibly, depending on its circumstances. Qualifying as a micro-entity affects how a company may prepare its statutory accounts — it does not create a separate or simplified version of the CT600, and it does not automatically remove Corporation Tax obligations. A micro-entity company that has been issued a notice to file by HMRC, or that has taxable profits, income or gains to report, will generally need to submit a Company Tax Return. Whether any Corporation Tax is actually payable is a different question and depends on the company's taxable position for the period.

How is taxable profit calculated from accounting profit?

The accounting profit shown in the company's accounts is usually the starting point for the Corporation Tax computation, but it is rarely the finishing point. Adjustments may be needed — for example adding back expenditure that is not allowable for tax purposes, deducting capital allowances instead of accounting depreciation, or recognising income and expenses in a different period for tax. Reliefs and losses brought forward may also affect the result. After these adjustments, the figure that emerges is the taxable profit, which may be higher or lower than the accounting profit and forms the basis for any Corporation Tax liability reported on the CT600.

Is filing a CT600 the same as paying Corporation Tax?

No. Filing the CT600 and paying any Corporation Tax due are separate obligations. Submitting the Company Tax Return tells HMRC what the company's taxable position is for the period; the tax itself must be paid separately, and the payment arrangements depend on the company's circumstances. A return may report a liability, a nil position, or a loss, so filing the form does not by itself mean tax has been settled.

What information is needed to prepare a CT600 Tax Return?

Typically you will need the company's accounts or detailed accounting records for the period, a breakdown of income and expenditure, details of any fixed asset purchases and disposals, information about losses brought forward or carried back, and details of any reliefs claimed. It also helps to have prior period returns, correspondence with HMRC, and records of any tax already paid. Having this information organised in advance makes CT600 Tax Return Filing much smoother and reduces the risk of queries later.

What happens if a company files its CT600 late?

Filing after the due date can lead to penalties and interest charges from HMRC, and the consequences generally become more significant the longer the return remains outstanding. The exact outcome depends on how late the filing is, whether any tax remains unpaid, and the company's wider compliance history, so it is not something that can be summed up with a single rule. If a deadline is at risk, it is usually best to speak to an accountant as early as possible about the options available.
