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

CT600 Tax Return Filing is how a UK company reports its Corporation Tax position to HM Revenue & Customs. Our service in Alderley Edge helps limited companies pull together the figures from their accounting records, work through any tax adjustments needed to arrive at taxable profit, prepare the Corporation Tax computation and submit the completed Company Tax Return to HMRC accurately and on time. It is important to understand that a CT600 is not the same thing as statutory accounts filed with Companies House, and it is not a Confirmation Statement, a VAT Return or a Self Assessment tax return. Statutory accounts and the CT600 are related but separate obligations, and the profit shown in your accounts is often not the same as the profit used for Corporation Tax purposes. Professional CT600 Tax Return Filing gives you a clear, organised route through the Corporation Tax process — so you know what has been filed, what it was based on, and what happens next — without tying up your own time in spreadsheets and HMRC online services.

 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.

 Trustindex verifies that the original source of the review is Google. I highly recommend Imran to anyone looking for a reliable and knowledgeable accountant. 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.

I'm very pleased with the service I've received and truly appreciate his support. If you need help with your accounts or taxes, I would highly recommend Imran.

What Is a Micro-Entity CT600 and How Does It Relate to CT600 Tax Return Filing?

There is no separate HMRC form called a “micro-entity CT600”. The CT600 is the standard Company Tax Return used by UK companies to report their Corporation Tax position to HMRC, and a company that prepares its accounts under the micro-entity regime still uses that same return where it is required to file one. The difference for a micro-entity lies mainly in how the statutory accounts are prepared and what they disclose, not in the tax return itself. Being a micro-entity does not remove Corporation Tax obligations automatically: whether a company needs to file a CT600, and whether any Corporation Tax is actually payable, depends on its own circumstances and taxable position — a company can be within the micro-entity accounting regime and still have no Corporation Tax to pay, or still have a return to submit. It is also worth separating three things that are often confused. Statutory accounts are prepared for the company’s members and filed with Companies House. The CT600 is submitted to HMRC as the Company Tax Return. The Corporation Tax computation sits alongside the CT600 and explains how taxable profit was reached. Accounting profit and taxable profit are not always the same figure, because the tax calculation may require adjustments — for example, adding back disallowable expenditure, adjusting for capital allowances or accounting for income and expenses that are treated differently for tax. The accounting framework a company uses, such as FRS 105, does not itself determine the Corporation Tax liability. Finally, filing the CT600 and paying any Corporation Tax due are separate actions with separate requirements, so a submitted return does not by itself settle the tax position.

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 exactly is a CT600?

A CT600 is the form HMRC uses for a company's Company Tax Return. It reports the company's Corporation Tax position for an accounting period, including the figures on which the tax is based and the amount of Corporation Tax calculated as due. It is submitted to HMRC, not to Companies House, and it is specific to companies and other organisations within the charge to Corporation Tax rather than to individuals.

Who needs to file a CT600?

Most UK limited companies that are within the scope of Corporation Tax need to submit a Company Tax Return to HMRC, even where no tax ends up being payable. The exact position depends on the company's circumstances — for example, whether it has been actively trading, whether it has been dormant, or whether it has received a notice to deliver a return. Because the rules are circumstance-dependent, it is worth confirming your own position rather than assuming either that a return is definitely required or definitely not.

Is a CT600 different from statutory accounts?

Yes, and the two serve different purposes. Statutory accounts are the financial statements prepared for the company's members and filed with Companies House. The CT600 is the Company Tax Return submitted to HMRC. Many of the same underlying figures appear in both, but the accounts must follow the applicable accounting framework, while the CT600 reflects the Corporation Tax position. Filing one does not automatically satisfy the obligation to file the other.

Is a CT600 different from a Corporation Tax computation?

They are closely linked but not the same document. The Corporation Tax computation is the working paper that starts with accounting profit and applies the relevant adjustments to arrive at taxable profit and the resulting Corporation Tax liability. The CT600 is the return that reports those results to HMRC. In practice, a well-prepared computation acts as the supporting explanation for the figures entered in the CT600.

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

Possibly, depending on its circumstances. Preparing accounts under the micro-entity regime affects how the statutory accounts are drawn up, but it does not create a separate or simplified tax return, and it does not automatically exempt a company from Corporation Tax. A micro-entity company that is within the charge to Corporation Tax and has been required to deliver a return will still need to file a CT600. Where a company is dormant, or has no Corporation Tax liability, the position can differ, so it is sensible to check before assuming a return is or is not due.

What information is needed to prepare a CT600?

Typically you will need the company's accounting records and finalised accounts for the period, details of income and expenditure, information on fixed assets for capital allowances purposes, any expenses that may need to be added back in the tax computation, details of any other income such as bank interest, and the company's registration details including its Unique Taxpayer Reference. Where the company has claimed reliefs or has brought-forward losses, the supporting details should be available too.

How is taxable profit calculated from accounting profit?

The starting point is normally the profit shown in the accounts, but that figure then passes through a series of adjustments. Disallowable expenditure, such as certain entertaining costs, is added back; capital allowances may be deducted in place of depreciation; and income or expenses that are treated differently for tax are corrected. The result is taxable profit, which is then used to work out the Corporation Tax due. This is why the accounting profit in your statutory accounts and the taxable profit in your CT600 can be different numbers.

Is filing a CT600 the same as paying Corporation Tax?

No. Filing the CT600 is the reporting step — it tells HMRC what the company's position is for the accounting period. Paying Corporation Tax is a separate obligation, and the amount and timing of any payment depend on the company's circumstances and the liability calculated. A return can be filed showing nothing to pay, and conversely a liability can arise independently of when the return is submitted, so both should be tracked carefully.

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

Yes. A company can appoint an agent to prepare the Corporation Tax computation, complete the CT600 and submit the Company Tax Return to HMRC on its behalf, provided the necessary authorisation is in place. The company remains responsible for the accuracy of the information it provides and for meeting its own Corporation Tax obligations, which is why a good working relationship between the company and whoever prepares the return matters.
