 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.

Micro-Entities and the CT600: What It Means for CT600 Tax Return Filing

A micro-entity is a company that meets certain size criteria under UK company law, but there is no separate official ‘micro-entity CT600’ form. A micro-entity company may still have Corporation Tax obligations and, where required, must submit a Company Tax Return – the CT600 – to HMRC. The CT600 is separate from statutory accounts filed with Companies House, even though the accounting records and accounts often provide the starting point for the Corporation Tax calculation. Taxable profit can differ from accounting profit because the Corporation Tax computation may require adjustments, such as adding back disallowable expenses or claiming available reliefs. Filing a CT600 and paying Corporation Tax are also separate obligations: the return reports the position, while payment depends on whether Corporation Tax is due. Not every micro-entity will owe Corporation Tax; the company’s circumstances and taxable position determine whether tax is payable.

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 used to report a company's Corporation Tax position to HMRC. It is the Company Tax Return, not a set of statutory accounts. The CT600 brings together details of the company's income, gains, deductions and reliefs, and it shows how the Corporation Tax liability or repayable amount has been calculated. The figures usually start from the company's accounts, but they may need tax adjustments before the return is finalised. Filing the CT600 is a separate process from filing accounts with Companies House.

Is a CT600 different from statutory accounts?

Yes. Statutory accounts are prepared under company law and filed with Companies House, while a CT600 is a tax return filed with HMRC. The accounts show the company's financial performance and position, whereas the CT600 reports the Corporation Tax position. The two are connected because the accounts often provide the starting point for the tax computation, but they serve different purposes and have different filing routes. A company may need to file both, depending on its circumstances.

Who needs to file a CT600?

A company usually needs to file a Company Tax Return if HMRC has issued a notice to deliver one, or if the company has Corporation Tax obligations for the period. Whether a particular company must file depends on its circumstances, including whether it is active for Corporation Tax and what HMRC requires. A CT600 may be required even if no Corporation Tax is ultimately payable, because the filing obligation and the payment obligation are separate. If you are unsure, professional advice can help clarify your position.

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

A micro-entity company may need to file a CT600 if it has Corporation Tax obligations or if HMRC has issued a notice to deliver a Company Tax Return. Micro-entity status affects the accounting framework and the way statutory accounts may be prepared, but it does not automatically remove the need to report to HMRC. The CT600 is separate from the accounts filed with Companies House, and the company's accounting figures may need tax adjustments before the taxable profit is calculated. Not every micro-entity will owe Corporation Tax, but filing obligations still depend on the company's specific circumstances.

What information is needed to prepare a CT600?

To prepare a CT600, you generally need the company's accounting records and draft or final statutory accounts, along with details of income, expenses, capital expenditure, losses and any reliefs being claimed. Prior Corporation Tax computations and returns can also help maintain consistency. The preparation process may involve reviewing the accounting profit, identifying tax adjustments and calculating the taxable profit before completing the return. Accurate records make the CT600 Tax Return Filing process smoother and reduce the risk of avoidable errors.

How is taxable profit calculated from accounting profit?

Taxable profit starts with the accounting profit shown in the company's accounts, but it is not always the same figure used for Corporation Tax. The Corporation Tax computation may require adjustments, such as adding back expenses that are not allowable for tax, deducting allowable expenses or capital allowances, and accounting for losses or reliefs. These adjustments help arrive at the taxable profit on which Corporation Tax is calculated. Because the rules can depend on the company's activities and circumstances, the computation should be prepared carefully rather than simply copying the accounting profit.

Is filing a CT600 the same as paying Corporation Tax?

No. Filing a CT600 is the act of submitting the Company Tax Return to HMRC, while paying Corporation Tax is a separate obligation. The return reports the company's Corporation Tax position and shows whether tax is due, but submitting the return does not automatically settle any liability. A company may also need to make payments separately, depending on its circumstances. It is important to keep filing and payment responsibilities distinct and to seek advice if you are unsure what applies to your company.

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

Yes. A company can authorise an accountant or tax agent to prepare and file its CT600 with HMRC. The agent can help gather the relevant information, prepare the Corporation Tax computation, review tax adjustments and submit the Company Tax Return through the appropriate HMRC channel. Even when an agent is appointed, the company remains responsible for the accuracy of its return and for paying any Corporation Tax due. This can be particularly helpful for directors who want professional support with CT600 Tax Return Filing in Holywood.
