 Trustindex verifies that the original source of the review is Google. We worked with a few different accountants before finally settling with Accotax, and we’re really glad we did. Their team is great. Abdul is responsive and easy to reach whenever I have a question, which makes a big difference. They take the time to understand how our business works and what our needs are. They are very knowledgeable, and when they don’t have the answer straight away, they take the time to look into it and get back to us quickly. Anum, who looks after our account on a day-to-day basis, including reconciling invoices and preparing the annual accounts, is amazing. She is professional, efficient, and follows the processes we have put in place together. She's also very quickin getting back to us whenever needed. We’re very happy to work with her and hope to continue doing so for as long as possible. Overall, Accotax has made our accounting experience much smoother and easier. We see them as a long-term partner as our business continues to grow. I would 100% recommend them.

 Trustindex verifies that the original source of the review is Google. I have really impressed to date with all dealings with Accotax highly enough. From day one, they've made what can often be a complicated and stressful part of running a business feel straightforward and hassle-free. A special mention has to go to Anum, who has been friendly, incredibly responsive, and genuinely cares about providing the best possible service. No question is ever too much trouble, and she consistently goes above and beyond to make sure everything is dealt with efficiently. I wouldn't hesitate to recommend you to anyone looking for an accountant they can genuinely trust.

What a CT600 Means for Micro-Entity Companies

There is no separate “micro-entity” version of the CT600. The CT600 is the Company Tax Return that companies use to report their Corporation Tax position to HMRC, and a company that qualifies as a micro-entity under its chosen accounting framework may still need to file one. Whether a CT600 is required, and whether Corporation Tax is actually payable, depends on the company’s own circumstances and taxable position rather than on its size alone. Where a return is needed, the figures in your statutory accounts — which are prepared and filed separately with Companies House — often form the starting point for the Corporation Tax computation, but they are not simply copied across. Accounting profit and taxable profit are different measures: a Corporation Tax calculation may require adjustments, such as adding back disallowable expenditure or deducting allowable reliefs, before taxable profit is established. It is also worth keeping in mind that submitting a CT600 and paying any Corporation Tax due are two separate obligations with their own processes and timetables.

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 Company Tax Return?

A CT600 is the formal Company Tax Return that a company submits to HMRC to report its Corporation Tax position for an accounting period. It sets out the company's income, gains, deductions and allowances, and the resulting Corporation Tax liability — or a nil position where none is due. The CT600 is filed with HMRC and is normally supported by a Corporation Tax computation and, where appropriate, a copy of the statutory accounts. It is a tax filing, not a Companies House filing, and it serves a completely different purpose from your annual accounts.

Is a CT600 different from statutory accounts and a Confirmation Statement?

Yes, these are separate obligations. Statutory accounts are prepared under an accounting framework and filed at Companies House. A Confirmation Statement is an annual confirmation of company details, also filed at Companies House. A VAT Return reports VAT to HMRC. The CT600 is the Company Tax Return submitted to HMRC to report Corporation Tax. The figures in your statutory accounts frequently feed into the Corporation Tax computation, but the accounts, the Confirmation Statement and the CT600 each serve a different purpose and go to a different place.

Who needs to file a CT600 Tax Return?

A company that has received a notice from HMRC requiring it to deliver a Company Tax Return must file one, and companies generally need to file for each accounting period in which they have taxable activity. Whether Corporation Tax is actually payable depends on the company's taxable profit and any reliefs available, so it is possible to have a filing obligation even where no tax is due. Because the requirement depends on each company's circumstances, it is worth checking your position if you are unsure.

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

It depends on the company's circumstances rather than on its size classification alone. Being a micro-entity is an accounting category based on the size thresholds in the relevant framework, and it does not remove a company's Corporation Tax obligations. If HMRC has issued a notice to deliver a return, or the company has taxable profits, a CT600 will usually need to be prepared and filed. Many micro-entities prepare fairly simple accounts yet still need a full Corporation Tax computation to support the return.

Is a CT600 different from a Corporation Tax computation?

Yes. The CT600 is the return itself — the form submitted to HMRC. The Corporation Tax computation is the working paper that sits behind it, showing how accounting profit is adjusted to arrive at taxable profit and how the liability has been calculated. HMRC expects the computation to support the figures shown on the return, so the two are normally prepared side by side, but they are distinct documents doing different jobs.

How is taxable profit calculated from accounting profit?

The starting point is usually the company's accounting profit for the period, taken from its accounts. That figure is then adjusted for items HMRC treats differently. For example, disallowable expenditure may be added back, capital allowances may be claimed in place of depreciation, and other reliefs may reduce the amount subject to tax. The result is the taxable profit on which Corporation Tax is calculated. Because the adjustments depend on the company's own activities and transactions, the calculation is specific to each business.

Is filing a CT600 the same as paying Corporation Tax?

No, they are separate obligations. Filing the CT600 tells HMRC what the company's Corporation Tax position is for the period. Paying Corporation Tax is a separate process with its own timetable and its own HMRC reference. A company can have a filing obligation even when no tax is payable, and a company with tax to pay must settle that liability regardless of when the return itself is submitted. Keeping both in view helps you manage cash flow and avoid unnecessary surprises.

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

Yes. Many companies appoint an accountant or tax adviser to prepare the Corporation Tax computation and submit the CT600 on the company's behalf. The company remains responsible for the accuracy of what is filed, which is why an adviser works from your accounting records and asks for supporting information. Where you use a professional service, the filing can be handled end to end — preparing the computation, reviewing the tax adjustments and submitting the Company Tax Return to HMRC.
