CT600 Tax Return Filing in Ashton-under-Lyne: Prepare and Submit Your Company Tax Return to HMRC

Professional CT600 Tax Return Filing in Ashton-under-Lyne helps your company bring together its Corporation Tax position and submit a Company Tax Return to HMRC with clarity and confidence. The CT600 is the return HMRC uses for Corporation Tax reporting, and it is a separate obligation from the statutory accounts your company files at Companies House — even though both are built from the same underlying accounting records. Working with an experienced team means your figures are properly organised, the tax adjustments that sit behind your taxable profit are considered carefully, and the return is prepared and filed accurately and within the expected timeframe. You get straightforward communication, a clear process from start to finish, and the reassurance that the numbers reported to HMRC reflect your company’s actual circumstances. Where relevant, we also explain how the CT600 fits alongside your other filing requirements, so nothing is confused with a Confirmation Statement, a VAT Return, or your annual accounts. The focus is on accuracy, convenience, and taking the administrative weight off your shoulders so you can concentrate on running the business.

 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 Relate to CT600 Tax Return Filing?

There is no separate official form called a “micro-entity CT600” — the CT600 is the single Company Tax Return form used for Corporation Tax reporting to HMRC, whatever the size of the company completing it. Where the term is used, it simply refers to CT600 Tax Return Filing for a company that meets the micro-entity size criteria for accounts purposes. A micro-entity company can still have Corporation Tax obligations and, where HMRC requires a Company Tax Return, will need to complete and submit a CT600 reporting its income, allowable deductions and overall Corporation Tax position. It is important to understand that the CT600 is separate from the statutory accounts a company files with Companies House: the accounts are a company law filing obligation, while the CT600 is a tax filing obligation, and the two serve different purposes even when they draw on the same figures. The accounting records and accounts a micro-entity prepares are often used as the starting point for the Corporation Tax calculation, but taxable profit can differ from accounting profit because the tax computation may require adjustments — for example, for items that are not allowable for tax or for income that is treated differently for tax purposes. It is also worth noting that the accounting framework a company uses, such as FRS 105, does not by itself determine the Corporation Tax liability; that is worked out through the tax computation. Not every micro-entity will owe Corporation Tax, as the amount payable depends on the company’s individual circumstances and its taxable position. Equally, submitting a CT600 and paying any Corporation Tax due are two distinct obligations — filing the return on time does not itself settle the tax, and payment arrangements need to be handled separately.

What is a CT600?

A CT600 is the formal Company Tax Return used to report a company's Corporation Tax position to HMRC. It sets out the company's income, allowable deductions, and the resulting taxable profit and Corporation Tax figure, along with other information HMRC requires about the company and its activities. Although it is often referred to casually as a Corporation Tax Return, the CT600 is a specific form submitted to HMRC rather than a set of accounts. It must be prepared from accurate accounting records and a properly worked Corporation Tax computation.

Who needs to file a CT600?

A company will generally need to file a Company Tax Return where HMRC has issued a notice to deliver one, and companies that are liable to Corporation Tax are usually expected to report their position this way. The precise position depends on the company's circumstances — for example, whether it has been trading, whether it has been dormant, and whether HMRC has asked for a return. Because the requirement is not identical for every company, it is sensible to check your own situation rather than assuming either that you must file or that you need not.

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

Yes, they are two separate filing obligations. Statutory accounts are prepared for the company's members and filed with Companies House under company law, while the CT600 is a tax return submitted to HMRC under tax law. Both are usually based on the same underlying bookkeeping, but they are not the same document and one does not replace the other. Filing statutory accounts does not satisfy your Company Tax Return obligation, and filing a CT600 does not satisfy your Companies House obligation.

Is a CT600 different from a Corporation Tax computation?

They are related but distinct. The Corporation Tax computation is the working document that starts with your accounting profit and applies the necessary tax adjustments to arrive at taxable profit and the resulting Corporation Tax position. The CT600 is the return form through which those figures are reported to HMRC. You cannot sensibly complete the CT600 without first having a computation you are confident in, because the figures on the return need to be supported by the calculation behind them.

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

Possibly, depending on its circumstances. Meeting the micro-entity criteria affects the accounting framework and disclosures used for the statutory accounts, but it does not remove a company's Corporation Tax reporting obligations. If HMRC requires a Company Tax Return, the company will need to submit a CT600 regardless of its size, and the accounting figures prepared under the micro-entity framework are typically used as the starting point for the tax computation. Not every micro-entity will have Corporation Tax to pay, but that is a question of the company's taxable position rather than its size.

What information is needed to prepare a CT600?

You will typically need the company's accounting records and finalised accounts, details of income and expenses for the period, information about any disallowable or non-trading items, capital allowances claims, and any other reliefs or adjustments relevant to the year. Basic company details, the accounting period dates, and prior period information may also be needed. The cleaner and more complete your records are, the smoother the process tends to be, which is one reason keeping Corporation Tax records organised throughout the year pays off at filing time.

How is taxable profit calculated from accounting profit?

The starting point is normally the profit shown in the accounts, which is then adjusted through a Corporation Tax computation to reach taxable profit. Typical adjustments include adding back expenses that are not allowable for tax, deducting items treated differently for tax purposes, and accounting for capital allowances in place of depreciation. The result can differ meaningfully from the accounting profit, which is why the computation matters as much as the reported accounts. The exact adjustments depend on the company's own transactions and circumstances.

Is filing a CT600 the same as paying Corporation Tax?

No — filing the return and paying any tax due are separate obligations. Submitting a CT600 reports your Corporation Tax position to HMRC, but it does not itself transfer any money or settle the liability. If Corporation Tax is payable, the payment needs to be arranged separately, and a company may still need to file a return even where no tax is due. Keeping the two processes clearly separate in your mind helps avoid the common mistake of assuming a filed return means everything is dealt with.
