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

CT600 Tax Return Filing in Horsforth means preparing and submitting a company’s Corporation Tax Return to HMRC — the return that reports the company’s income, deductible costs, allowances and reliefs, and its resulting Corporation Tax position for an accounting period. It is not the same thing as statutory accounts. Statutory accounts are prepared under an accounting framework and filed with Companies House, while a CT600 is filed with HMRC and is usually supported by a Corporation Tax computation that works from the accounting figures to arrive at taxable profit. That step matters, because accounting profit and taxable profit are often different: disallowable expenditure may need adding back, capital allowances and reliefs may need claiming, and the figures on the return need to tie back to the accounts. Our Horsforth team prepares CT600 Tax Return Filing for limited companies, building a clear computation from your records and submitting the Company Tax Return to HMRC on your behalf. You get an accurate return, an explanation of how the numbers were reached, and one less filing deadline to worry about.

 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.

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 Apply to Micro-Entity Companies in Horsforth?

There is no separate official “micro-entity CT600” form. The CT600 is the standard Corporation Tax Return that companies use to report their Corporation Tax position to HMRC, and it applies in the same way whether a company prepares accounts under the micro-entity regime, small company regime or full framework. “Micro-entity” describes the size of a company for accounts purposes and the accounting framework it may use when preparing its statutory accounts — it does not create a distinct tax return or remove Corporation Tax obligations. A micro-entity company can still be within the charge to Corporation Tax and, where its circumstances require it, will need to submit a Company Tax Return to HMRC. The CT600 is separate from the statutory accounts filed with Companies House, even though the two are related: the accounts and accounting records usually feed into the Corporation Tax calculation. Taxable profit is not automatically the same as the accounting profit shown in the accounts, because the Corporation Tax computation may require adjustments — for example, adding back disallowable expenses or claiming capital allowances and reliefs. It is also important not to confuse the filing of a CT600 with the payment of Corporation Tax. Filing is a reporting obligation; payment is a separate obligation, and whether any Corporation Tax is actually payable depends on the company’s taxable position and its circumstances.

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 HMRC uses for a company's Corporation Tax Return. It is submitted to HMRC, normally online, and sets out the company's income, expenses, allowances and reliefs for an accounting period along with the resulting Corporation Tax figure. The CT600 is usually supported by a Corporation Tax computation and by a copy of the company's accounts, and the figures across those documents need to be consistent. It is a tax return rather than a set of statutory accounts, and it is not filed with Companies House.

Who needs to file a CT600?

Broadly, UK limited companies and other organisations within the charge to Corporation Tax need to deliver a Company Tax Return to HMRC for each accounting period, even where no Corporation Tax turns out to be payable. That is why a company can owe nothing in tax and still have a filing obligation. Some companies that are dormant for Corporation Tax purposes can notify HMRC instead of filing, but that depends on the company's circumstances and HMRC's guidance. If you are unsure whether a return is expected for your company, it is worth checking before the period ends rather than afterwards.

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

Yes — they are two separate documents with two separate audiences. Statutory accounts are prepared under an accounting framework, such as FRS 105 or FRS 102, and are filed at Companies House. A CT600 is a tax return filed with HMRC, reporting the company's Corporation Tax position. The underlying figures usually link, because both start from the company's accounting records, but the purpose, format and destination are different, and the filing obligations arise independently of one another.

Is a CT600 different from a Corporation Tax computation?

Yes. The Corporation Tax computation is the working document that starts with the accounting profit from the accounts and makes the adjustments needed to arrive at taxable profit and the Corporation Tax liability. The CT600 is the return form on which the results of that computation are reported to HMRC. In practice the two travel together, which is why a return prepared without a proper computation behind it is difficult to check or explain later.

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

Micro-entity status affects how a company prepares and files its accounts; it does not create a separate form or a special tax regime. If a micro-entity company is within the charge to Corporation Tax, it may still need to submit a Company Tax Return to HMRC, depending on its circumstances and whether HMRC has asked for one. Preparing simpler accounts under the micro-entity regime does not determine the company's Corporation Tax liability — that is worked out through the Corporation Tax computation, which may include adjustments to the accounting figures.

How is taxable profit calculated from accounting profit?

The starting point is normally the profit shown in the accounts, but that figure is rarely the taxable profit. The computation adds back expenditure that is not allowable for tax purposes, deducts capital allowances in place of depreciation where relevant, and takes account of reliefs, losses and other adjustments available to the company. The result is the taxable profit on which Corporation Tax is calculated. Because these adjustments depend on the company's specific transactions and circumstances, the gap between accounting profit and taxable profit can vary considerably from one company to another.

Is filing a CT600 the same as paying Corporation Tax?

No. Filing the CT600 is a reporting obligation — it tells HMRC what the company's taxable position is. Paying Corporation Tax is a separate obligation, and the two do not necessarily fall due at the same time. A company can file its return and have no tax to pay, and conversely a company can have tax to pay before its return is submitted. Filing a Company Tax Return late, or paying Corporation Tax late, can lead to penalties and interest from HMRC, with the amount depending on how late things are and the company's circumstances.

Can Micro Entity Accounts prepare and file a CT600 on behalf of a company?

Yes. We can act on your company's behalf to prepare the CT600 Tax Return Filing, build the Corporation Tax computation, review the adjustments between accounting profit and taxable profit, and submit the Company Tax Return to HMRC. To do that we typically need your accounting records or completed accounts, details of income and expenditure, information on capital purchases and any previous losses or reliefs, plus confirmation of the accounting period. We will tell you exactly what is needed once we understand your company's position.
