 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.

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.

Is There a Separate Micro-Entity CT600? How CT600 Tax Return Filing Works for Smaller Companies

Micro-entity status describes how a company prepares and files its statutory accounts — it is not a separate type of tax return. There is no separate official “micro-entity CT600”: a company that meets the micro-entity criteria still uses the standard CT600 Company Tax Return when it needs to report to HMRC. A micro-entity company can have Corporation Tax obligations, and where HMRC requires a Company Tax Return, the CT600 is the form used to report the company’s Corporation Tax position. The CT600 is separate from the statutory accounts a company files with Companies House, although the accounting records and accounts often provide the starting point for the Corporation Tax computation. That computation may involve adjustments — for example, adding back expenses that are not allowable for tax, or accounting for reliefs and allowances that are not reflected in the accounts — which means taxable profit can differ from accounting profit. Equally, not every micro-entity will owe Corporation Tax; whether any tax is payable depends on the company’s own circumstances and its taxable position. It is also worth remembering that filing a CT600 and paying any Corporation Tax due are separate obligations: submitting the return does not itself settle the tax, and payment is handled separately. If you are unsure how this applies to your company, taking advice early is sensible.

What is a CT600?

A CT600 is the Company Tax Return used to report a UK company's Corporation Tax position to HMRC. It sets out the company's taxable profits and the Corporation Tax due for the accounting period, together with supporting information and computations. It is a tax filing rather than a set of financial statements, and it is submitted to HMRC rather than to Companies House.

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

Yes, they are separate filings with separate purposes. Statutory accounts are the financial statements a company prepares and files with Companies House, showing its performance and financial position for the period. A CT600 is the Company Tax Return submitted to HMRC, reporting the Corporation Tax position. They draw on much of the same information, but they go to different bodies, serve different audiences and can be due on different dates. In practice, the accounts are usually finalised first so that the figures can feed into the Corporation Tax computation.

Who needs to file a CT600?

A company will generally need to file a Company Tax Return where HMRC has issued a notice to deliver one, or where the company has taxable profits or gains for the period. Some companies with no Corporation Tax to pay still have a filing obligation if a notice has been issued. Whether a particular company must file therefore depends on its own circumstances and on any notices it has received from HMRC, so it is worth checking rather than assuming that no return is required.

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

Micro-entity status is an accounting framework for statutory accounts — it is not a tax status and it does not remove any Corporation Tax filing obligation. If a micro-entity company has received a notice to deliver a Company Tax Return, or has taxable profits for the period, it will usually need to file a CT600 in the same way as any other company. Filing accounts under the micro-entity regime does not determine the Corporation Tax position, and it is possible for a micro-entity to have no Corporation Tax to pay at all depending on its taxable profits and any reliefs available.

How is taxable profit calculated from accounting profit?

The starting point is normally the profit shown in the company's accounts. From there, a Corporation Tax computation makes adjustments to arrive at taxable profit: expenses that are not allowable for tax are added back, items that are allowable but not reflected in the accounts are deducted, and available reliefs and allowances are applied. Depreciation charged in the accounts, for example, is typically replaced with capital allowances. The result — taxable profit — can be higher or lower than accounting profit, and it is that figure which drives the Corporation Tax liability.

Is filing a CT600 the same as paying Corporation Tax?

No. Filing the CT600 reports the company's Corporation Tax position to HMRC, while paying any Corporation Tax due is a separate obligation with its own timeline. Submitting the return does not automatically settle the tax, and making a payment does not remove the need to file the return. Both should be tracked carefully, because the date by which a return must be filed and the date by which tax must be paid are not necessarily the same.

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

Yes. A director or company secretary can authorise an accountant or tax agent to prepare and file the Company Tax Return with HMRC on the company's behalf. The company itself remains responsible for the accuracy of what is submitted, so it is important to provide complete records and to review the figures before filing. An agent can also prepare the supporting Corporation Tax computation, including the adjustments made to the accounting figures.

What happens if a company files its CT600 late?

HMRC may charge penalties and interest where a Company Tax Return is filed after the deadline, and late payment of Corporation Tax can lead to further charges. The amount depends on factors such as how late the return is and how much tax remains outstanding. If you think a deadline may be missed, it is usually better to speak to an accountant straight away so the position can be managed and the necessary information pulled together as quickly as possible.
