CT600 Tax Return Filing in Coatbridge — Prepare and Submit Your Company Tax Return to HMRC

If your company needs to report its Corporation Tax position to HMRC, CT600 Tax Return Filing is the process that gets it done. We help companies in Coatbridge and across the UK prepare their CT600 — the formal Company Tax Return — by reviewing the accounting figures, considering the tax adjustments that may be needed, and submitting the return to HMRC on the company’s behalf. It is important to understand that a CT600 is not the same thing as the statutory accounts filed with Companies House. Statutory accounts are a separate filing obligation, prepared under an applicable accounting framework, while the CT600 reports the company’s taxable position to HMRC. Because the two processes are linked but distinct, working with someone who understands both can make the whole exercise far clearer. Our approach focuses on accuracy, plain-English explanations and convenience, so you know what has been filed, why the figures look the way they do, and what happens next.

 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.

What Does a CT600 Mean for a Micro-Entity Company?

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 whatever size the company is. What does differ is the context. A company that operates as a micro-entity may prepare its statutory accounts under a simplified accounting framework and may file simpler accounts with Companies House, but it can still have Corporation Tax obligations. Where HMRC requires it, the company needs to submit a Company Tax Return (CT600), and the accounting records and accounts it has prepared are typically the starting point for that return. The CT600 itself is separate from the statutory accounts: one goes to HMRC, the other to Companies House, and they are filed under different rules. It is also worth understanding that the figures in the accounts do not always flow straight into the tax return. A Corporation Tax computation may require adjustments — for example, adding back disallowable expenditure or accounting for capital allowances and other reliefs — so the taxable profit can differ from the accounting profit shown in the accounts. Not every micro-entity will owe Corporation Tax; whether any is payable depends on the company’s circumstances and its taxable position. Equally, filing a CT600 and paying Corporation Tax are two separate obligations: the return reports the position, while payment is handled through HMRC’s own process.

What is a CT600?

A CT600 is the form used to submit a Company Tax Return to HMRC. It reports the company's Corporation Tax position for an accounting period, including details of income, allowable deductions and the resulting tax calculation. It is filed electronically with HMRC and is used by companies of all sizes, not just large ones. The CT600 sits alongside, but is distinct from, the statutory accounts a company files with Companies House.

Is a Company Tax Return the same as statutory accounts?

No. Statutory accounts are prepared for the company's members and filed with Companies House, usually under an accounting framework such as FRS 105 or FRS 102. A Company Tax Return, submitted as a CT600, goes to HMRC and reports the company's Corporation Tax position. The two are related because the accounts often provide the starting point for the tax figures, but they are separate documents with separate filing obligations and separate audiences.

Who needs to file a CT600?

A company normally needs to file a Company Tax Return if HMRC has issued a notice to deliver one, and most active companies with taxable activity will need to file. Whether a return is required in any particular year depends on the company's circumstances — for example, a dormant or non-trading company may not need to file, but that depends on its situation and on what HMRC has asked for. If you are unsure whether your company needs to file, it is worth checking rather than assuming.

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

There is no separate micro-entity version of the CT600 — the same Company Tax Return applies. What may differ is how the statutory accounts are prepared, since micro-entity companies can often use a simplified accounting framework for Companies House filings. That does not remove Corporation Tax obligations on its own. A micro-entity company may still need to submit a CT600 if HMRC requires one, and the accounts it has prepared will usually feed into the Corporation Tax calculation. Whether any Corporation Tax is actually payable depends on the company's taxable position.

Is a CT600 different from a Corporation Tax computation?

Yes. The Corporation Tax computation is the working paper that starts with the accounting profit from the accounts and applies the necessary tax adjustments — such as adding back disallowable expenditure or claiming capital allowances — to arrive at the taxable profit and the resulting Corporation Tax liability. The CT600 is the return form on which those figures are reported to HMRC. You generally need the computation to complete the CT600 accurately, so the two are closely connected but serve different purposes.

How is taxable profit calculated from accounting profit?

Taxable profit is not simply the profit shown in the accounts. The Corporation Tax computation begins with accounting profit and then makes adjustments to reflect tax rules. Typical adjustments might include adding back expenses that are not allowable for tax, deducting capital allowances instead of depreciation, and accounting for reliefs or income that is treated differently for tax purposes. The exact adjustments depend entirely on the company's transactions and circumstances, which is why a careful review of the accounts matters before a CT600 is filed.

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

Yes. A company can appoint an accountant or tax agent to prepare the Company Tax Return and submit it to HMRC on its behalf. This usually involves granting the agent the appropriate HMRC authorisation so they can file the return and act for the company. Many businesses take this route because it reduces the risk of errors, keeps the Corporation Tax records organised, and gives them a clear explanation of how the figures were arrived at.

Is filing a CT600 the same as paying Corporation Tax?

No — filing and payment are separate obligations. Filing the CT600 reports the company's Corporation Tax position to HMRC, while paying Corporation Tax is a separate act that the company must handle through HMRC's payment process. Submitting the return does not by itself settle any liability, and paying an amount does not remove the need to file. It is important to keep both in view so nothing is overlooked.

What happens if a company files its CT600 late?

If a Company Tax Return is filed late, HMRC may apply penalties and interest, and the amount involved depends on how late the return is and on HMRC's published guidance at the time. Corporation Tax may also be treated as due regardless of whether the return has been submitted. Because the consequences vary with the company's circumstances, the best approach if you are worried about a late or missing return is to speak to an accountant promptly rather than wait.
