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.

 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 Is a CT600, and How Does It Apply to a Micro-Entity Company?

“Micro-entity” describes a company that qualifies for the small companies regime and prepares simpler accounts — it is not a different type of tax return. There is no separate official micro-entity CT600 form: a micro-entity company uses the same Company Tax Return framework as any other UK company where it is within the charge to Corporation Tax and HMRC has issued a notice to deliver a return. The CT600 is submitted to HMRC and reports the company’s Corporation Tax position for an accounting period. It is not the same as the statutory accounts filed with Companies House, and completing one does not satisfy the other. The company’s accounting records and accounts usually form the starting point for the Corporation Tax calculation, but taxable profit can differ from accounting profit because the computation may require adjustments — for example, adding back disallowable expenditure, replacing depreciation with capital allowances, or bringing in reliefs and losses where the rules allow. Not every micro-entity owes Corporation Tax; whether any tax is payable depends on the company’s taxable position and its particular circumstances, and filing a CT600 with HMRC is a separate obligation from paying any Corporation Tax that is due.

3 months late	A further £100
6 months late	HMRC estimates your tax bill and adds 10% of the unpaid tax
12 months late	A further 10% of any unpaid tax

Penalty levels are set by Companies House and may change. Separate HMRC penalties and interest apply to a late Corporation Tax return and unpaid tax. Check the updated guide here.

─── FAQs

Micro-Entity CT600 FAQs

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 HMRC uses for a company's Company Tax Return. It reports the company's Corporation Tax position for an accounting period, including income, allowable deductions, reliefs and the resulting Corporation Tax liability, or a nil position where no tax is due. It is submitted to HMRC rather than to Companies House, and it is usually supported by a Corporation Tax computation that shows how the figures were arrived at.

Is a CT600 different from the statutory accounts filed with Companies House?

Yes, they are separate documents with different purposes and different recipients. Statutory accounts are prepared under an accounting framework and filed with Companies House, and they are also generally submitted to HMRC alongside the return. A CT600 is the Company Tax Return submitted to HMRC to report the Corporation Tax position. The accounts often provide the starting point for the return, but the figures in them are not automatically the figures used for Corporation Tax.

Who needs to file a CT600?

A company generally needs to file a Company Tax Return where it is within the charge to Corporation Tax and HMRC has issued a notice to deliver a return. Whether a return is required therefore depends on the company's own circumstances — for example whether it has been actively trading, whether HMRC has asked it to file, and whether any exemption or dormancy position applies. If you are unsure where your company stands, it is worth checking the position rather than assuming no return is needed.

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

A micro-entity company operates under the same Corporation Tax filing framework as any other company. Where it is within the charge to Corporation Tax and HMRC has issued a notice to deliver a return, it will normally need to submit a CT600, regardless of the simpler accounts it may prepare under the small companies regime. Being a micro-entity does not automatically mean Corporation Tax is payable — that depends on the company's taxable position — and filing the CT600 is a separate obligation from paying any Corporation Tax that is due.

How is taxable profit calculated from accounting profit?

The starting point is usually the accounting profit shown in the company's accounts, which is then adjusted to arrive at taxable profit. Typical adjustments include adding back expenditure that is not allowable for tax purposes, removing items that are not taxable, replacing depreciation with capital allowances where they are available, and reflecting losses and reliefs in line with the rules for the period. The result is the taxable profit on which the Corporation Tax position is based, and it can differ meaningfully from the accounting profit.

Is filing a CT600 the same as paying Corporation Tax?

No. Filing the CT600 reports the company's position and the amount of Corporation Tax that is due, while payment of any liability is a separate obligation handled through HMRC's payment channels. Filing a return showing tax due does not settle the liability, and making a payment does not remove the requirement to file the return. The amount payable and the relevant dates depend on the company's circumstances and the rules for the accounting period concerned.

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

Yes. A company can appoint an agent to prepare and submit its Company Tax Return, which is one of the main reasons businesses seek professional support. We can prepare the CT600, work through the Corporation Tax computation and tax adjustments, and file the return with HMRC on your behalf. The company directors remain responsible for the accuracy of the information provided and for ensuring any Corporation Tax due is paid.

What happens if a CT600 is filed late?

Filing a Company Tax Return after the date HMRC expects it can lead to penalties and to interest on any unpaid Corporation Tax, and the exact consequences depend on how late the return is and on the company's circumstances. Because the position varies from case to case, it is best to look at HMRC's published guidance or take advice on your particular situation. If a return is already overdue, getting the records organised and bringing the filing up to date promptly is usually the sensible next step.
