 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 Micro-Entity CT600 and How Does It Fit with CT600 Tax Return Filing?

There is no separate official “micro-entity CT600” form. The CT600 is the standard Company Tax Return used to report a company’s Corporation Tax position to HMRC, and it applies to companies generally, whatever their size and whichever accounting framework they use. A company that qualifies as a micro-entity may still have Corporation Tax obligations, and where HMRC requires it, that company will need to submit a Company Tax Return using the CT600. It is important to separate this from your statutory accounts: the accounts are prepared and filed with Companies House under the relevant accounting framework, while the CT600 is filed with HMRC for Corporation Tax purposes. The figures in your accounting records and accounts often form the starting point for the Corporation Tax calculation, but taxable profit is not automatically the same as accounting profit. The Corporation Tax computation may require adjustments, such as adding back disallowable expenditure or deducting items treated differently for tax, before taxable profit and any Corporation Tax liability are determined. Because a micro-entity’s circumstances vary, it does not follow that every micro-entity will owe Corporation Tax, and it is also worth remembering that filing the CT600 and paying any Corporation Tax due are separate obligations with their own timelines.

6 months late	HMRC estimates your tax bill and adds 10% of the unpaid tax

What is a CT600?

A CT600 is the form used to submit a Company Tax Return to HMRC. It reports a company's Corporation Tax position for an accounting period, including figures such as turnover, trading profits and the amount of Corporation Tax that the company considers is due, along with the tax computations that support those figures. It is submitted electronically to HMRC and forms part of the company's formal Corporation Tax reporting record.

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

Yes, and the distinction matters. Statutory accounts are prepared under the relevant accounting framework and filed with Companies House as a public record of the company's financial position and performance. The CT600 is a tax return filed with HMRC, not Companies House. The two documents are prepared for different audiences and purposes, although they draw on the same underlying accounting records. Filing accounts does not satisfy the CT600 obligation, and filing a CT600 does not replace the requirement to file accounts where one applies.

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

It can do. Being a micro-entity affects how the statutory accounts are prepared, not whether a Company Tax Return is required. Whether a particular company needs to file a CT600 depends on its circumstances and on what HMRC has asked for, for example whether the company has received a notice to deliver a return. If your company has received such a notice, a return is normally required even if no Corporation Tax turns out to be payable. It is worth checking your position rather than assuming that small size removes the obligation.

Is a CT600 the same as a Corporation Tax computation?

No. The computation is the working paper that starts with the company's accounting profit, applies the relevant tax adjustments, and arrives at taxable profit and the resulting Corporation Tax figure. The CT600 is the return that reports the outcome of that work to HMRC. In practice the two are prepared together, because the boxes on the CT600 need to be supported by a computation that explains how the figures were reached.

How is taxable profit worked out from accounting profit?

The starting point is usually the profit shown in the accounts for the accounting period. From there, adjustments are made for items treated differently for tax purposes. Common examples include adding back expenditure that is not allowable for tax, and accounting for income or deductions that are recognised on a different basis for tax. Capital allowances may also replace or reduce the depreciation charged in the accounts. The result is the taxable profit used to calculate the Corporation Tax liability, which can be higher or lower than the accounting profit depending on the company's transactions.

Is filing a CT600 the same as paying Corporation Tax?

They are separate obligations. Submitting the CT600 tells HMRC what the company's Corporation Tax position is for the period, while payment is a distinct step with its own timing. A company can have a filing obligation even where no Corporation Tax is payable, and conversely the payment due is not settled simply by submitting the return. It is sensible to keep both in view so that neither is overlooked.

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 to HMRC, and the company remains responsible for the accuracy of what is filed and for its wider tax position. Working with a professional typically means the accounting records are reviewed, the tax adjustments are considered, a Corporation Tax computation is prepared, and the CT600 is submitted on your behalf. You should expect to be asked for information and to review the figures before submission.

What information is needed to prepare a CT600?

As a general guide, the preparer will need the company's accounting records and accounts for the period, details of income and expenditure, information on fixed asset additions and disposals, and any relevant notes on items that may need tax adjustment. Details of any payments already made towards Corporation Tax, plus any earlier periods still open, can also be relevant. If records are incomplete or transactions are unusual, expect follow-up questions, as the quality of the return depends on the quality of the information behind it.
