CT600 Tax Return Filing in Kingsbury — Company Tax Return Preparation and Submission to HMRC

CT600 Tax Return Filing in Kingsbury gives your company a clear, professionally managed route to reporting its Corporation Tax position to HMRC. The CT600 is the Company Tax Return — the return used to report your company’s income, deductions, allowances and reliefs, and the resulting Corporation Tax position for an accounting period. Preparing it well means starting from reliable accounting records, reviewing the figures for tax adjustments, and building a Corporation Tax computation that explains how taxable profit has been arrived at. It is important to remember that the CT600 is a separate filing from the statutory accounts your company prepares and submits to Companies House, and separate again from obligations such as Confirmation Statements and VAT Returns. With professional support, the process becomes far more straightforward: your records are organised, tax adjustments are considered properly, the computation is documented, and the Company Tax Return is prepared and submitted to HMRC on your behalf.

 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 Does a CT600 Mean for a Micro-Entity Company? Understanding CT600 Tax Return Filing

There is no separate official “micro-entity CT600” form. A micro-entity is a company that meets the relevant size criteria to use the micro-entity accounts regime, but for tax purposes it deals with the same CT600 — the Company Tax Return — as any other UK company that is required to file one. A micro-entity company may still have Corporation Tax obligations, and where HMRC requires a Company Tax Return, that return needs to be prepared and submitted. The CT600 is separate from the statutory accounts: the accounts are prepared under the company’s chosen accounting framework and filed with Companies House, while the CT600 reports the company’s tax position to HMRC. The figures in the accounts are usually the starting point for the tax calculation, but taxable profit can differ from accounting profit, because a Corporation Tax computation may require adjustments — for example, adding back disallowable expenditure or claiming capital allowances. Accounting framework and tax liability are therefore related but not the same thing: using the micro-entity regime does not by itself determine what Corporation Tax is due. Whether Corporation Tax is actually payable depends on the company’s circumstances and its taxable position, and filing the CT600 is a separate obligation from paying any Corporation Tax that may be due.

What is a CT600?

A CT600 is the form used to submit a Company Tax Return to HMRC. It reports your company's Corporation Tax position for an accounting period — the income it has received, the deductions, allowances and reliefs it is claiming, and the resulting Corporation Tax liability or repayment position. The CT600 is filed with HMRC and is a completely separate submission from the statutory accounts a company files at Companies House. In practice, the CT600 is usually accompanied by, or supported by, a Corporation Tax computation showing how the taxable profit figure was calculated.

Who needs to file a CT600?

Whether a particular company needs to file depends on its circumstances. Broadly, a UK company must deliver a Company Tax Return to HMRC where HMRC has issued a notice to deliver a return, or where the company has taxable profits or other circumstances that require a return for the period. It is the company's own responsibility to make sure any required return is prepared and submitted, even if an accountant or agent handles the work. Because the answer genuinely turns on your company's position, it is worth checking your obligations for each accounting period rather than assuming a previous year's pattern still applies.

Is a CT600 different from the statutory accounts?

Yes — they are two distinct documents with two different recipients. Statutory accounts are prepared under an accounting framework and filed with Companies House, and they present the company's financial position and performance for the period. The CT600 is a tax return submitted to HMRC, reporting the company's Corporation Tax position. The figures in the accounts often form the starting point for the tax return, but the accounts themselves do not calculate the tax. Filing one does not discharge the obligation to file the other, and each has its own requirements and its own submission route.

Is a CT600 different from a Corporation Tax computation?

They are closely related but not the same thing. The Corporation Tax computation is the working paper that starts with your accounting profit and adjusts it — adding back disallowable expenditure, deducting allowable items and capital allowances, and dealing with any losses or other reliefs — to arrive at the taxable profit and the Corporation Tax figure. The CT600 is the return form on which those results are reported to HMRC. In practice they are prepared together, because the CT600 boxes need the computation figures behind them, but the computation is the explanation and the CT600 is the submission.

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

Micro-entity status relates to the size criteria for the accounts regime a company uses, not to Corporation Tax. There is no separate micro-entity version of the CT600. Where HMRC requires a Company Tax Return, a micro-entity company files the same CT600 as any other company, prepared from the same underlying accounting records. Whether Corporation Tax is actually payable is a separate question that depends on the company's taxable position and its circumstances for that period — so filing a return and owing tax are not automatically the same outcome.

How is taxable profit calculated from accounting profit?

The starting point is normally the company's accounting profit for the period, as shown in the accounts. From there, the tax computation adjusts the figure: expenditure that is not allowable for tax purposes is added back, allowable deductions and capital allowances are taken into account, and other items such as losses brought forward or specific reliefs are dealt with as appropriate. The result is the taxable profit, to which the applicable rate is applied to reach the Corporation Tax figure reported on the CT600. Because these adjustments vary from company to company, the taxable profit can be higher or lower than the accounting profit.

Is filing a CT600 the same as paying Corporation Tax?

No — filing and payment are separate obligations. Submitting a CT600 tells HMRC what your company's Corporation Tax position is for the period; it does not itself settle any liability. Arranging payment is a distinct step, with its own timetable and payment methods, and a company needs to manage both. It is worth keeping an eye on both dates independently, and if you are unsure how your company's filing and payment obligations interact, it is sensible to take advice on your specific position.

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

Yes. Companies commonly ask an accountant or tax agent to prepare the Corporation Tax computation and submit the Company Tax Return to HMRC on their behalf, which requires the appropriate authorisation and access to the company's HMRC account. Even where an agent handles the work, the company remains responsible for the accuracy of the information provided and for ensuring its filing and payment obligations are met. That is why good record-keeping and a clear line of communication between the company and the preparer matter so much.
