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.

 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-Entity Companies and CT600 Tax Return Filing: What You Need to Know

There is no separate micro-entity CT600 form. The CT600 is the standard Company Tax Return that a company may need to submit to HMRC to report its Corporation Tax position. A micro-entity company is not automatically outside the Corporation Tax system: depending on its circumstances and taxable position, it may still need to prepare and file a CT600 Tax Return. For a micro-entity company in Horsham, this means the usual Corporation Tax principles can apply even though the company may have simpler accounting and reporting considerations. The CT600 is separate from the statutory accounts filed with Companies House, and it is also separate from paying any Corporation Tax that may be due. Your accounting records and accounts can form the starting point for the Corporation Tax computation, but the taxable profit may differ from the accounting profit because the computation can require adjustments, such as adding back disallowable expenses or using available reliefs and allowances where relevant. The accounting framework used to prepare the accounts, such as FRS 105 for a micro-entity, does not by itself determine the company’s Corporation Tax liability. Accounts preparation and CT600 Tax Return Filing are related, but they are separate processes, and the support needed depends on the company’s specific circumstances.

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 submit a Company Tax Return to HMRC as part of CT600 Tax Return Filing. It reports a company’s Corporation Tax position for an accounting period, including income, profits, deductions and reliefs. A CT600 is not a VAT Return, a Confirmation Statement or a set of statutory accounts for Companies House.

Is a CT600 the same as statutory accounts?

No. Statutory accounts are prepared for the company’s members and filed with Companies House under company law. The CT600 is a tax return submitted to HMRC for Corporation Tax purposes. The figures in the accounts often feed into the Corporation Tax computation, but the CT600 reports the taxable position, which may be different from the accounting profit shown in the accounts.

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

It depends on the company’s circumstances. A micro-entity is an accounting classification and does not automatically mean the company has no Corporation Tax obligations or no requirement to file a Company Tax Return. If HMRC has issued a notice to deliver a Company Tax Return, or if the company has taxable profits or other circumstances requiring a return, a CT600 may be required. Some companies may not owe Corporation Tax but still need to file a return. It is best to check the position for the specific accounting period.

Is a CT600 different from a Corporation Tax computation?

Yes. The CT600 is the return form submitted to HMRC. The Corporation Tax computation is the working that starts with accounting profit and adjusts it to arrive at taxable profit before calculating any Corporation Tax due. The computation supports the figures entered on the CT600. Both may need to be prepared carefully, and the computation is where tax adjustments are usually explained.

Can a company file its CT600 without filing its accounts?

A CT600 and statutory accounts are separate filings, but they are connected for tax purposes. In many cases, accounts and a tax computation need to be submitted to HMRC alongside the Company Tax Return, depending on the company’s situation and how the return is filed. Statutory accounts are still filed with Companies House separately. A company should not assume that filing one removes the need for the other.

How is taxable profit calculated from accounting profit?

The Corporation Tax computation usually starts with the accounting profit shown in the company’s accounts. Certain items may then be added back if they are not allowable for tax, and other deductions or reliefs may be claimed where the rules allow. The result is the taxable profit used to determine the Corporation Tax liability. This means taxable profit can be higher or lower than accounting profit, and the adjustments depend on the company’s specific transactions and circumstances.

Is filing a CT600 the same as paying Corporation Tax?

No. Filing the CT600 is the reporting obligation: it tells HMRC about the company’s Corporation Tax position for the period. Paying Corporation Tax is a separate obligation, and any payment due must be made in line with HMRCu2019s rules and deadlines. A company might file a CT600 showing no Corporation Tax payable, or it might file and then need to arrange payment separately.

What happens if a company files its CT600 late?

If a Company Tax Return is filed late, HMRC may apply penalties and interest under its published rules. The exact consequences depend on the filing date, the amount of tax unpaid and HMRCu2019s guidance, so it is important to check the current position and act promptly if a deadline is at risk. If you are unsure whether a return is due, or you need help with CT600 Tax Return Filing, professional support can help you understand the next steps.
