 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 Does CT600 Tax Return Filing Mean for a Micro-Entity Company in Kingston?

For a micro-entity company in Kingston, CT600 Tax Return Filing is about meeting the company’s Corporation Tax obligations, not about using a separate official micro-entity CT600 form. A micro-entity is still a limited company for tax purposes, and it may need to submit a Company Tax Return to HMRC if it has taxable profits, receives a notice to file, or otherwise has a requirement to report its Corporation Tax position. The CT600 is separate from the statutory accounts filed with Companies House, even though both may start from the same accounting records. Accounting profit can be the starting point for the Corporation Tax computation, but taxable profit may differ because adjustments can be needed, such as adding back disallowable expenses, claiming allowable capital allowances, or dealing with income and costs in a different way for tax purposes. Not every micro-entity will owe Corporation Tax; whether tax is payable depends on the company’s taxable position and circumstances. Filing the CT600 and paying any Corporation Tax due are also separate obligations, so submitting the return does not automatically settle a tax bill.

What is a CT600?

A CT600 is the form HMRC uses for a Company Tax Return. It reports your company's Corporation Tax position, including the figures used to calculate taxable profit and any Corporation Tax due. The CT600 is submitted to HMRC, usually through compatible software, and it is not the same document as the statutory accounts filed with Companies House. Think of the CT600 as the tax return, while the statutory accounts are the company law accounts.

Is a CT600 different from statutory accounts?

Yes. Statutory accounts are prepared under company law and filed with Companies House. A CT600 is a Company Tax Return submitted to HMRC for Corporation Tax purposes. The two documents may start from the same accounting records, but they serve different audiences and can include different information. Statutory accounts do not replace a CT600, and filing a CT600 does not automatically file your statutory accounts with Companies House.

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

A micro-entity company in Kingston is not exempt from CT600 Tax Return Filing simply because it is small. If the company is liable to Corporation Tax, or if HMRC has issued a notice to file, it may need to submit a Company Tax Return. Some companies may have no Corporation Tax to pay but still need to file, depending on their circumstances. The right answer depends on the company's taxable position and HMRC's requirements.

Is a CT600 different from a Corporation Tax computation?

Yes. The CT600 is the actual return form sent to HMRC. A Corporation Tax computation is the supporting calculation that starts with accounting profit and makes tax adjustments to arrive at taxable profit and the Corporation Tax liability. The computation feeds the figures reported on the CT600, but the two are not the same thing.

What information is needed to prepare a CT600?

To prepare a CT600, you generally need the company's accounting records, profit and loss account, balance sheet, details of income and expenses, information on fixed assets, any tax adjustments, and prior-year tax returns or computations. HMRC references, company registration details, and records of any Corporation Tax payments can also be useful. Accurate records make the CT600 Tax Return Filing process smoother and reduce the risk of queries.

How is taxable profit calculated from accounting profit?

Taxable profit usually starts with the accounting profit shown in the company's accounts. Adjustments may then be made, such as adding back disallowable expenses, deducting allowable capital allowances, removing non-taxable income, or applying available reliefs where the rules permit. The result is the taxable profit used to calculate Corporation Tax. The exact adjustments depend on the company's activities and circumstances, which is why a Corporation Tax computation matters.

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. Paying Corporation Tax is a separate obligation. A company can have a filing requirement even if no Corporation Tax is payable, and any tax due must be paid separately according to HMRC's rules. Meeting one obligation does not automatically satisfy the other.

What happens if a company files its CT600 late?

If a CT600 is filed late, HMRC may take action under its late filing rules. The consequences can depend on how late the return is, whether the company has a reasonable excuse, and other circumstances. Filing as soon as possible and seeking professional advice can help you understand the position, but no particular outcome can be guaranteed.
