CT600 Tax Return Filing in Kingsbridge – 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 Kingsbridge can take the guesswork out of the process. We help you pull together the figures from your accounting records, review the tax adjustments that may be needed to arrive at your taxable profit, prepare the CT600, and submit the Company Tax Return to HMRC on your behalf. It is important to understand that a CT600 is not the same thing as your statutory accounts: statutory accounts are filed separately with Companies House, while the CT600 is the Company Tax Return submitted to HMRC. The two are connected through your accounting figures, but they serve different purposes and follow different rules. Our focus is on accuracy, a clear explanation of what has been reported and why, and making the whole exercise as convenient as possible for directors who would rather spend their time running the business than deciphering tax forms.

 Trustindex verifies that the original source of the review is Google. We worked with a few different accountants before finally settling with Accotax, and we’re really glad we did. Their team is great. Abdul is responsive and easy to reach whenever I have a question, which makes a big difference. They take the time to understand how our business works and what our needs are. They are very knowledgeable, and when they don’t have the answer straight away, they take the time to look into it and get back to us quickly. Anum, who looks after our account on a day-to-day basis, including reconciling invoices and preparing the annual accounts, is amazing. She is professional, efficient, and follows the processes we have put in place together. She's also very quickin getting back to us whenever needed. We’re very happy to work with her and hope to continue doing so for as long as possible. Overall, Accotax has made our accounting experience much smoother and easier. We see them as a long-term partner as our business continues to grow. I would 100% recommend them.

 Trustindex verifies that the original source of the review is Google. I have really impressed to date with all dealings with Accotax highly enough. From day one, they've made what can often be a complicated and stressful part of running a business feel straightforward and hassle-free. A special mention has to go to Anum, who has been friendly, incredibly responsive, and genuinely cares about providing the best possible service. No question is ever too much trouble, and she consistently goes above and beyond to make sure everything is dealt with efficiently. I wouldn't hesitate to recommend you to anyone looking for an accountant they can genuinely trust.

What Is a CT600 and How Does It Relate to Micro-Entity Companies in Kingsbridge?

There is no separate official “micro-entity CT600”. The CT600 is the standard Company Tax Return form used to report a company’s Corporation Tax position to HMRC, and it applies to companies generally, whatever their size. Where a micro-entity company is within the charge to Corporation Tax, it may still be required to submit a Company Tax Return, and where that is the case the CT600 is the form used. It sits alongside — but is distinct from — your statutory accounts, which are prepared under your chosen accounting framework and filed with Companies House as a separate obligation. A micro-entity company’s accounts and accounting records often form the starting point for the Corporation Tax calculation, because the figures that appear in the accounts are used to build the tax position reported on the CT600. That said, the accounting profit shown in the accounts is not automatically the same as the taxable profit used for Corporation Tax. Corporation Tax calculations may require adjustments — for example, to add back certain disallowable expenses or to account for timing differences and reliefs that apply to your particular circumstances — before the taxable profit and any resulting Corporation Tax liability can be determined. It is also worth being clear that filing a CT600 and paying Corporation Tax are two separate obligations: the return reports the position, while payment is a distinct matter that depends on whether any Corporation Tax is actually due. Not every micro-entity will owe Corporation Tax, and whether a return is required, and what it should contain, depends on the company’s own circumstances and taxable position rather than on its size alone. Choosing a micro-entity accounting framework does not by itself determine your Corporation Tax liability; it affects how the accounts are prepared, and the tax position is then worked out separately.

─── FAQs

Micro-Entity CT600 FAQs

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 formal Company Tax Return that a UK company submits to HMRC to report its Corporation Tax position for an accounting period. It sets out details of the company's income, expenses, profits and the tax calculation, along with any reliefs or allowances being claimed. The CT600 is a tax filing to HMRC — it is not the same document as the statutory accounts a company files with Companies House, even though the two are closely related because both draw on the same underlying accounting records.

Who needs to file a CT600?

A company generally needs to file a Company Tax Return where it is within the charge to Corporation Tax, for example where it has trading profits, investment income or chargeable gains, or where HMRC has issued a notice to deliver a return. The precise position depends on the company's own circumstances, and some companies may have periods where no return is required or where a return is required even though no tax ends up being payable. Because the rules turn on your specific situation, it is worth checking rather than assuming — an accountant can confirm whether a CT600 is required for your accounting period and help you prepare it if so.

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

Yes, they are two separate filings with two separate purposes. Statutory accounts are prepared under your chosen accounting framework and filed at Companies House, where they become part of the public record. A CT600 is a tax return submitted to HMRC to report the company's Corporation Tax position. The accounts usually provide the starting figures for the tax work, but the CT600 itself contains tax-specific information and a computation that does not appear in the Companies House filing. Meeting one obligation does not automatically satisfy the other.

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

It can do, yes. Being a micro-entity affects how your accounts are prepared and what you are required to file at Companies House, but it does not exempt a company from Corporation Tax or from filing a Company Tax Return where one is required. Whether a particular micro-entity needs to file a CT600 depends on its circumstances and taxable position during the accounting period. Equally, filing a CT600 does not automatically mean Corporation Tax is payable — the return reports the position, and payment is a separate matter.

Is a CT600 the same as a Corporation Tax computation?

No, though the two go hand in hand. The Corporation Tax computation is the working document that starts with your accounting profit and makes the adjustments needed to arrive at taxable profit — for example, adding back expenses that are not allowable for tax and accounting for capital allowances or other reliefs. The CT600 is the return form on which the results of that computation are reported to HMRC. In practice, the computation supports the figures entered on the CT600, which is why getting the underlying calculation right matters so much.

How is taxable profit calculated from accounting profit?

Taxable profit starts with the profit shown in your accounts and is then adjusted to reflect Corporation Tax rules. Common adjustments include adding back expenditure that is not deductible for tax purposes, deducting items that are deductible for tax but were not charged in the accounts, and accounting for capital allowances on qualifying assets, which replace the depreciation charged in the accounts. There may also be timing differences, losses brought forward and reliefs to consider. The result is the taxable profit on which any Corporation Tax liability is based — and it can be higher or lower than the accounting profit shown in your accounts.

Is filing a CT600 the same as paying Corporation Tax?

No. Filing the CT600 and paying any Corporation Tax that is due are separate obligations with separate timescales. The CT600 reports the company's position and tells HMRC what tax, if any, is payable, but submitting the return does not itself settle the liability. Equally, a company can have a filing obligation even where no Corporation Tax is payable. It is important to keep both aspects in mind and to make sure any payment due is dealt with separately from the filing itself.

Can someone prepare and file a CT600 on my company's behalf?

Yes. A company can appoint an accountant or tax agent to prepare the CT600 and submit it to HMRC on its behalf, usually with authorisation to deal with HMRC for Corporation Tax matters. To do this well, the preparer will typically need your accounting records, details of income and expenditure, information on assets purchased or sold, and any earlier computations or losses to carry forward. Once the figures are agreed, the return can be prepared, reviewed with you, and filed — which is often a good option if you would rather not work through the tax adjustments yourself.
