 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.

Micro-Entity Companies and the CT600: What You Need to Know

There is no separate “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 is used by companies of all sizes — including companies that qualify as micro-entities for accounting purposes. A micro-entity company may still have Corporation Tax obligations and, where HMRC requires it, will need to submit a Company Tax Return (CT600). The CT600 is separate from the statutory accounts that a company files with Companies House, although the figures in those accounts, along with the underlying accounting records, are often the starting point for the Corporation Tax calculation. Crucially, a company’s taxable profit can differ from its accounting profit, because the Corporation Tax computation may require adjustments — for example, adding back disallowable expenditure or claiming available reliefs — before taxable profit and any Corporation Tax liability are determined. Whether Corporation Tax is actually payable depends on the company’s own circumstances and taxable position, and filing the CT600 is a separate obligation from paying any Corporation Tax that is due. Filing your CT600 Tax Return and settling any liability are two distinct steps, and both need to be dealt with on their own terms.

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.

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. It sets out a company's Corporation Tax position for an accounting period, including the figures for income and expenditure, the taxable profit or loss calculated in the Corporation Tax computation, and any deductions or reliefs that apply. It is completed and submitted to HMRC, not to Companies House, and it is a tax document rather than a set of financial statements.

Who needs to file a CT600 Tax Return with HMRC?

In general, a company that is within the scope of Corporation Tax — including many limited companies — is expected to notify HMRC that it is trading and to submit a Company Tax Return when required. Whether a specific company needs to file for a particular period depends on its own circumstances, such as whether it has been sent a notice to deliver a return, its trading activity, and its taxable position. If you are unsure about your company's situation, it is worth checking with an accountant rather than assuming either way.

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

Yes, and it is a common point of confusion. Statutory accounts are prepared for the company's members and filed with Companies House as part of the company's public filing obligations. A CT600 is a tax return submitted to HMRC to report the company's Corporation Tax position. They are separate documents with separate purposes and separate submission routes, even though both draw on the same underlying accounting records. Filing one does not automatically satisfy the other.

Is a CT600 different from a Corporation Tax computation?

They are related but not the same thing. The Corporation Tax computation is the working document that starts with the accounting profit shown in the accounts and adjusts it to arrive at the taxable profit — for example by adding back disallowable expenses or applying available reliefs. The CT600 is the return itself, which reports the results of that computation to HMRC. The computation supports the figures on the return and should be prepared carefully, as it explains how the taxable profit was reached.

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

A micro-entity is an accounting classification, and it does not determine a company's Corporation Tax obligations on its own. A company that qualifies as a micro-entity may still be within the scope of Corporation Tax and, where HMRC requires it, will need to submit a Company Tax Return in the usual way. Equally, not every micro-entity will have a Corporation Tax liability in every period — that depends on the company's taxable position. Filing the return and paying any tax due are separate matters.

What information is needed to prepare a CT600 Tax Return?

Typically we need your accounting records for the period, the accounts prepared for the company, details of income and expenditure, information on any capital expenditure and depreciation, records of director's loans or other balances where relevant, and details of any reliefs or allowances you may be able to claim. Having your bookkeeping up to date makes the process smoother and reduces the number of queries raised along the way.

How is taxable profit calculated from accounting profit?

Taxable profit is not simply the profit shown in your accounts. The Corporation Tax computation begins with the accounting profit and then makes adjustments. Certain expenses that are allowable for accounting purposes are not allowable for tax and may be added back, while other items such as capital allowances may be deducted. The result is the taxable profit, which is the figure used to determine any Corporation Tax liability. Because these adjustments depend on your company's specific transactions, the computation should be prepared case by case.

Is filing a CT600 the same as paying Corporation Tax?

No — filing and payment are separate obligations. Submitting your CT600 to HMRC reports your company's Corporation Tax position for the period, but it does not by itself settle any tax that is due. Any liability arising from the computation still needs to be paid to HMRC through the appropriate payment route and within the relevant timescale for your company. It is sensible to plan for both the filing and the payment so that neither is overlooked.
