CT600 Tax Return Filing in Altrincham — Prepare and File Your Company Tax Return with HMRC

If your company needs to report its Corporation Tax position to HMRC, professional CT600 Tax Return Filing in Altrincham takes the guesswork out of the process. We help you pull together the figures from your accounting records, prepare the Corporation Tax computation that sits behind the return, review the tax adjustments and allowances involved, and submit your Company Tax Return to HMRC accurately and on time. It is worth being clear about one thing from the outset: a CT600 is not the same as your statutory accounts. Your accounts are filed with Companies House under an accounting framework, while the CT600 is the Corporation Tax Return filed with HMRC. Those are two separate obligations with two separate audiences, and the figures are not always identical. We handle both sides of that distinction so nothing gets muddled, from checking the profit figures through to filing online. The result is a straightforward, transparent process with properly documented figures, so you know exactly what has been submitted, on what basis, and why.

 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 Is a Micro-Entity CT600 and How Does It Relate to CT600 Tax Return Filing?

There is no separate official “micro-entity CT600” form. A micro-entity company that has Corporation Tax obligations files the same Company Tax Return — the CT600 — as any other limited company. What tends to differ is the size and complexity of the figures behind it. A company that qualifies as a micro-entity will often prepare simpler statutory accounts under a reduced disclosure framework, but that accounting choice does not, by itself, determine what Corporation Tax is due. The CT600 is a separate filing made to HMRC, distinct from the statutory accounts filed with Companies House, and it reports the company’s taxable position for an accounting period. In practice, the profit shown in the accounts is frequently the starting point for the Corporation Tax computation, but it is rarely the final figure. Adjustments may be required — for example, adding back expenditure that is not allowable for tax purposes, removing income that is not taxable, or claiming capital allowances in place of depreciation — before taxable profit is arrived at and the Corporation Tax position can be reported. Whether a micro-entity company actually owes Corporation Tax depends entirely on its own circumstances and taxable position, and the filing obligation is separate from the payment obligation: submitting a CT600 and paying any Corporation Tax due are two different things, with their own requirements. If you are unsure whether a return is needed for your company, it is worth checking HMRC’s guidance or speaking to an accountant before assuming either way.

Let Us Take Care of Your CT600 Tax Return Filing in Altrincham

What is a CT600?

A CT600 is the form HMRC uses to submit a Company Tax Return. It sets out the company's income, gains, deductions and reliefs for an accounting period and reports the resulting Corporation Tax position. It is filed with HMRC rather than Companies House and is normally submitted online. In most cases the CT600 is supported by a Corporation Tax computation showing how the figures were arrived at, and often by a copy of the statutory accounts as well. Think of the CT600 as the formal return, and the computation as the workings behind it.

Who needs to file a CT600?

A company generally needs to file a Company Tax Return where HMRC has issued a notice to deliver one, and in certain other circumstances set out in HMRC's guidance — for example where the company has taxable profits or other chargeable amounts. There are situations where a return is still required even though no Corporation Tax ends up being payable, so the presence or absence of a tax bill is not always a reliable guide. Because the position depends on the individual company's activities and circumstances, it is always worth confirming rather than assuming.

Is a CT600 different from statutory accounts?

Yes, they are separate documents with separate purposes. Statutory accounts are prepared under an accounting framework and filed with Companies House, where they become part of the public record. A CT600 is the Company Tax Return submitted to HMRC, reporting the company's Corporation Tax position. The two share a starting point — your accounting records — but the figures are not necessarily the same, because the tax return reflects taxable profit after adjustments rather than accounting profit. Filing one does not satisfy the obligation to file the other.

Is a CT600 different from a Corporation Tax computation?

They are closely related but not the same thing. The Corporation Tax computation is the set of workings that begins with the accounting profit shown in the accounts, applies the necessary tax adjustments, accounts for allowances and losses, and arrives at the taxable profit and the resulting Corporation Tax liability. The CT600 is the return on which those figures are reported to HMRC. The computation explains and supports the numbers; the CT600 is the submission itself. In practice they are prepared side by side.

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

Possibly, yes. Being a micro-entity is about the size of the company and the accounting framework it uses to prepare its accounts — it is not a tax status and it does not exempt a company from HMRC filing requirements. A company that qualifies as a micro-entity can still have Corporation Tax obligations and may need to submit a Company Tax Return. Equally, being a micro-entity does not automatically mean Corporation Tax is payable; that depends on the company's taxable profits and its particular circumstances. The accounting framework used for the accounts does not on its own determine the tax liability.

How is taxable profit calculated from accounting profit?

The usual starting point is the accounting profit shown in the company's accounts. From there, adjustments are made: expenditure that is not allowable for tax purposes is generally added back, income that is not taxable is removed, depreciation is typically replaced by capital allowances, and losses brought forward or other available reliefs are taken into account. What remains is the taxable profit, on which the Corporation Tax liability is calculated under the rules that apply to the accounting period. Because the adjustments depend on the company's own transactions, the figures should be reviewed carefully rather than lifted straight from the accounts.

Is filing a CT600 the same as paying Corporation Tax?

No — filing and payment are two separate obligations. Submitting the CT600 tells HMRC what the company's Corporation Tax position is; paying any Corporation Tax due is a distinct step with its own timing. A company can file its return on time and still owe tax, or file a return that shows no liability at all. It is worth diarising both requirements so that neither is overlooked, and keeping clear records of what was filed and what was paid.

What happens if a company files its CT600 late?

Where a Company Tax Return is filed late, HMRC may charge penalties, and interest can also arise where Corporation Tax is paid late. Longer or repeated delays can increase the level of exposure. The exact outcome depends on the circumstances of the company and on HMRC's published guidance, so it is not something that can be stated as a fixed rule. If you think a filing date may be missed, it is generally better to speak to HMRC or your accountant as early as possible rather than waiting.
