 Trustindex verifies that the original source of the review is Google. I worked with Accotx on a HMRC reclaim and overall, they did ultimately deliver on their promise, which I appreciate. The process did take longer than any of us expected, partly due to external delays with the tax authorities, and partly because there were some hiccups in communication and follow-up. However, despite those challenges, they stayed professional and stuck to the original agreed terms. If you’re considering using them, be prepared to stay in regular contact to keep things moving along. They are absolutely capable, have the expertise and willing to work with you, and overall  improving their services over time. I would certainly return for any future needs.

 Trustindex verifies that the original source of the review is Google. I highly recommend Imran to anyone looking for a reliable and knowledgeable accountant. 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.

What Is a CT600 and How Does It Relate to Micro-Entity Companies?

A CT600 is the core form used to submit a Company Tax Return to HMRC and report a company’s Corporation Tax position. There is no separate official ‘micro-entity CT600’; micro-entity status relates to the accounts and reporting framework a company may use, not to a different HMRC tax return. A micro-entity company can still have Corporation Tax obligations and, where HMRC requires it, must submit a Company Tax Return. The CT600 is not the same as statutory accounts filed with Companies House, and it is also not the same as paying Corporation Tax. The accounting records and accounts may be used as the starting point for the Corporation Tax computation, but taxable profit can differ from accounting profit because adjustments may be needed for items such as disallowable expenses, non-taxable income, capital allowances, losses or reliefs. A micro-entity may not necessarily owe Corporation Tax, as the company’s taxable position and circumstances determine whether tax is payable, and filing the CT600 is a separate obligation from making any Corporation Tax payment. For CT600 Tax Return Filing in Aberystwyth, the key is to keep the accounts, computation and HMRC submission aligned without treating them as the same task. Choosing a framework such as FRS 105 affects how accounts are prepared, but it does not by itself determine the company’s Corporation Tax liability.

1 day late	£100
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.

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 and how does it differ from a Company Tax Return?

A CT600 is the main form used to submit a Company Tax Return to HMRC. The Company Tax Return is the broader filing that reports your company's Corporation Tax position, and the CT600 is the core document within that process. It sets out income, gains, deductions, reliefs and the resulting Corporation Tax calculation. Depending on the company's circumstances, supplementary pages or attachments such as accounts and a tax computation may also be required. The CT600 is filed with HMRC, not Companies House, and it is separate from statutory accounts and from payment of Corporation Tax.

Who needs to file a CT600?

A company or unincorporated association that is liable to Corporation Tax, or that has been notified by HMRC that a Company Tax Return is required, generally needs to file a CT600. Not every company will owe Corporation Tax, but a return may still be required depending on HMRC notices and the company's circumstances. This is why it is important to check the company's position rather than assuming that no tax due means no filing obligation. If you are unsure whether CT600 Tax Return Filing applies to your company in Aberystwyth, professional advice can help clarify the requirement.

Is a CT600 different from statutory accounts?

Yes. Statutory accounts are prepared under company law and filed with Companies House, while a CT600 is submitted to HMRC as part of the Company Tax Return for Corporation Tax. The accounts may provide the starting figures, but the CT600 and any supporting Corporation Tax computation can include tax adjustments that are not shown in the accounts. Filing statutory accounts with Companies House does not automatically file your CT600, and the two obligations should be tracked separately.

Is a CT600 different from a Corporation Tax computation?

Yes. The CT600 is the return form submitted to HMRC, while the Corporation Tax computation is the detailed calculation that explains how accounting profit has been adjusted to arrive at taxable profit. The computation may deal with disallowable expenses, non-taxable income, capital allowances, losses, reliefs and timing differences. HMRC may expect the computation to support the figures in the CT600, so the two documents usually need to be prepared together even though they serve different purposes.

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

It depends on the company's circumstances. Micro-entity status affects the accounts and reporting framework the company may use; it does not create a separate micro-entity CT600 or automatically remove Corporation Tax obligations. If the company is liable to Corporation Tax, or if HMRC requires a Company Tax Return, then CT600 Tax Return Filing may be necessary. A micro-entity company may still need to prepare accounts and a Corporation Tax computation, and it may not owe any Corporation Tax depending on its taxable profits and reliefs. Filing the CT600 and paying Corporation Tax are separate steps.

Is filing a CT600 the same as paying Corporation Tax?

No. Filing the CT600 is the act of submitting the Company Tax Return to HMRC and reporting the Corporation Tax position. Paying Corporation Tax is a separate obligation that depends on whether tax is due and when HMRC expects payment. A company can file its CT600 and still have no Corporation Tax to pay, or it may need to make a payment separately. Keeping the filing and payment dates and records organised helps avoid confusion, but the two should not be treated as the same task.

What information is needed to prepare a CT600?

To prepare a CT600, you generally need the company's accounting records, statutory accounts or draft accounts, details of income and expenses, capital purchases and disposals, any losses or reliefs, and information about tax already paid or credits due. A Corporation Tax computation is also usually needed to adjust accounting profit to taxable profit. Additional information may be required depending on the company's activities, such as property income, loans to directors, research and development claims, or foreign income. Good records make CT600 Tax Return Filing more efficient and reduce the risk of queries.

What happens if a company files its CT600 late?

If a CT600 is filed late, HMRC may charge penalties and interest, and the exact outcome depends on the circumstances and HMRC's rules. Late filing can also lead to additional correspondence, delays in agreeing the Corporation Tax position, and unnecessary administrative pressure. The best approach is to know the filing date that applies to your company's accounting period, prepare the accounts and computation early, and seek professional support if you are concerned about meeting the deadline. If you have already missed a date, it is usually better to act promptly rather than wait.
