CT600 Tax Return Filing in Chelmondiston – Prepare and File Your Company Tax Return with HMRC

CT600 Tax Return Filing in Chelmondiston gives your company a clear, professionally managed route to reporting its Corporation Tax position to HMRC. The CT600 is the Company Tax Return: it sets out the company’s income, allowable expenses and deductions for an accounting period, together with the resulting Corporation Tax position, and it is submitted to HMRC rather than to Companies House. It is a separate obligation from the statutory accounts you file with Companies House, from your Confirmation Statement, and from any VAT Returns the company completes. Professional support means your accounting figures are reviewed properly, any tax adjustments needed to arrive at taxable profit are considered, and the return is prepared and filed accurately and on time, saving you the administration and the uncertainty of working through HMRC’s requirements alone. Whether you are filing for the first time or want your existing filing handled more smoothly, CT600 Tax Return Filing in Chelmondiston is designed to be straightforward, transparent and convenient.

 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.

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

There is no separate official “micro-entity CT600” form. Every company that needs to submit a Company Tax Return to HMRC uses the CT600, regardless of its size, and the term “micro-entity CT600” is really shorthand for how a smaller company handles its CT600 Tax Return Filing. A company that meets the micro-entity criteria for accounts purposes may still have Corporation Tax obligations, and where HMRC requires a Company Tax Return, that return has to be completed and filed. The CT600 is separate from the statutory accounts a company files with Companies House, although the figures in those accounts, along with the underlying accounting records, often form the starting point for the Corporation Tax calculation. This is where care is needed: accounting profit is not automatically the same as taxable profit. The Corporation Tax computation may require adjustments — for example, adding back disallowable expenditure, deducting capital allowances in place of depreciation, or accounting for income and expenses that are treated differently for tax purposes. The accounting framework a company uses, such as FRS 105, governs how the accounts are prepared; it does not by itself determine the company’s Corporation Tax liability. Equally, not every micro-entity company will owe Corporation Tax, since that depends on the company’s own circumstances and taxable position. Filing the CT600 and paying any Corporation Tax due are also two distinct obligations with their own timings, so a filed return does not in itself settle a tax bill. In short, micro-entity companies have the same CT600 Tax Return Filing requirement where HMRC has asked for a return, simply with accounting figures that are typically smaller and simpler to review.

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?

The CT600 is the form used to submit a Company Tax Return to HMRC. It reports a company's income, gains, allowable deductions and reliefs for an accounting period, and it arrives at the company's Corporation Tax position for that period. It is filed with HMRC, not with Companies House, and it is normally submitted alongside a Corporation Tax computation and, where relevant, a copy of the statutory accounts. Think of the CT600 as the reporting document and the computation as the workings that sit behind the figures it contains.

Who needs to file a CT600?

A company normally needs to file a Company Tax Return where HMRC has issued a notice to deliver a return, and companies can also be required to file when they have taxable income or gains, when HMRC asks for one, or where they have been trading and are within the charge to Corporation Tax. A company that has been dormant in the strict HMRC sense may not need to file, but if HMRC has issued a notice, the return still has to be dealt with even if no tax is payable. Because the position depends on the company's own circumstances, it is worth confirming your obligation before assuming a return is unnecessary.

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

Yes. The statutory accounts are prepared under an accounting framework, approved by the directors and filed with Companies House as part of the company's public filing obligations. The CT600 is a tax return submitted to HMRC. The two are connected — the accounts usually provide the starting figures for the Corporation Tax computation — but they are separate documents, separate filings, and they can have separate deadlines. Filing one does not satisfy the other, so a company needs to keep both obligations in view.

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

Possibly. There is no separate micro-entity version of the CT600 — a micro-entity company uses the same CT600 as any other company where HMRC requires a Company Tax Return. Small size does not automatically remove the obligation to file, and it does not automatically mean Corporation Tax is payable either; that depends on the company's taxable position. What micro-entity status typically affects is how the accounts are prepared and how much detail they contain, not which tax return has to be submitted.

Is a CT600 different from a Corporation Tax computation?

Yes, and the distinction matters. The Corporation Tax computation is the working paper that starts with the company's accounting profit and adjusts it to arrive at taxable profit — for example by adding back disallowable expenditure and replacing accounting depreciation with capital allowances where applicable. The CT600 is the return that reports the outcome of that computation to HMRC. You can have a computation without a return and a return that is only as reliable as the computation behind it, which is why both are normally prepared together.

Is filing a CT600 the same as paying Corporation Tax?

No. Filing the return and paying any Corporation Tax due are separate obligations with their own timings, and meeting one does not discharge the other. A company may file its CT600 and owe nothing, or it may owe tax that has to be paid under HMRC's payment rules. It is worth keeping an eye on both, because a company can be up to date with its return and still have an outstanding liability, or vice versa.

What information is needed to prepare a CT600 in Chelmondiston?

Typically we need the company's accounting records and a set of figures for the period, such as a trial balance or profit and loss account with a balance sheet, together with details of income, expenditure, fixed asset purchases and disposals, any other income or gains, and the company's registration details. Information on earlier losses, capital allowances claims and any prior returns helps too. If the company has already prepared its accounts, we can work from those and focus on the tax adjustments needed for the computation.

What happens if a company files its CT600 late?

Late filing can lead to penalties and interest from HMRC, and the exposure generally grows the longer the return is outstanding. HMRC sets the deadline based on the company's accounting period, and it can be different from the Companies House deadline for the accounts, which catches some directors out. If you think a return is going to be late, it is better to speak to us early so we can look at the position, get the figures sorted and submit as soon as possible rather than let the delay run on.
