CT600 Tax Return Filing in Limavady – 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 Limavady gives you a clear, structured route from your accounting records through to a submitted Company Tax Return.

 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 Limavady?

There is no separate official ‘micro-entity CT600’ form. A CT600 is simply the Company Tax Return that a UK company uses to report its Corporation Tax position to HMRC, and it is the same core return whether the company is large, small, or a micro-entity. What differs is the surrounding detail: a micro-entity may prepare simpler statutory accounts under a reduced disclosure framework, but that has no bearing on whether a CT600 is required or on how the Corporation Tax liability is calculated. Where a company is within the charge to Corporation Tax and HMRC has issued a notice to deliver a return, it will generally need to submit a Company Tax Return, which includes the CT600 and the supporting accounts and computations. Importantly, the CT600 is separate from the statutory accounts filed with Companies House — these are two distinct filing obligations with two different bodies. The accounting records and accounts prepared for the company may feed into the Corporation Tax calculation, but the figures often need adjustment. Accounting profit and taxable profit are not automatically the same: items such as disallowable expenditure, capital allowances, and other tax-specific treatments can mean the taxable profit differs from the profit shown in the accounts. Finally, filing a CT600 and paying Corporation Tax are separate matters. A return may be filed even where no Corporation Tax is payable, depending on the company’s circumstances and taxable position, and submitting the return does not by itself settle any liability that may be due.

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 form used to submit a Company Tax Return to HMRC. It sets out the company's Corporation Tax position for an accounting period, including details such as the company's turnover, the profit figure used for tax purposes, and the tax that is due or repayable. It is filed electronically with HMRC alongside the supporting accounts and a tax computation, and it is the return HMRC relies on to assess the company's Corporation Tax position.

Who needs to file a CT600?

A company will generally need to file a Company Tax Return where HMRC has issued a notice to deliver one. This applies to most active limited companies, and in some circumstances it can also apply to a company that has been dormant or has made no profit. Because the requirement depends on the company's circumstances and on whether a notice has been issued, it is worth checking your position rather than assuming you can skip the return. If you are unsure whether a CT600 is needed for a particular accounting period, we can review your situation for you.

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

Yes — they are separate obligations handled by separate bodies. Statutory accounts are filed with Companies House and provide a public, statutory view of the company's financial position and performance. A CT600 is filed with HMRC and reports the company's Corporation Tax position. The two are related because both draw on the same underlying accounting records, but the format, purpose, and recipients are different, and neither filing removes the need for the other.

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

A micro-entity company can still have Corporation Tax obligations, and where HMRC has issued a notice to deliver a return, the company will generally need to submit a Company Tax Return. There is no separate 'micro-entity CT600' — the same CT600 is used. Simpler accounts under a micro-entity framework do not remove the need to report to HMRC, and they do not automatically determine the Corporation Tax liability. It is also worth remembering that filing a return is not the same as owing tax: whether any Corporation Tax is payable depends on the company's circumstances and its taxable position.

How is a Corporation Tax computation different from the CT600 itself?

The CT600 is the return form; the Corporation Tax computation is the working paper that supports it. The computation starts with the accounting profit from the company's accounts, adds back items that are not allowable for tax, deducts reliefs and allowances where they apply, and arrives at the taxable profit and the resulting Corporation Tax figure. The CT600 then reports that outcome to HMRC. Getting the computation right is what makes the figures on the CT600 defensible, which is why the two are prepared together.

How is taxable profit calculated from accounting profit?

Accounting profit is the starting point, but it usually needs adjusting before it becomes taxable profit. Common adjustments include adding back expenditure that is not allowable for tax purposes, such as certain entertaining costs, and deducting tax-specific reliefs such as capital allowances in place of the depreciation charged in the accounts. Other adjustments may apply depending on what the company has done during the period. Because these adjustments depend on the individual company's transactions, taxable profit often differs from the profit shown in the accounts — sometimes by a small amount, sometimes by considerably more.

Is filing a CT600 the same as paying Corporation Tax?

No, they are separate. Filing the CT600 is about reporting the company's Corporation Tax position to HMRC, while paying Corporation Tax is about settling any liability that is due. A company can file its return and have no payment to make, or it can have a liability that must be paid under the applicable payment rules. Keeping the two distinct helps avoid the common mistake of assuming that submitting the return has dealt with the tax itself.

What happens if a company files its CT600 late?

If a Company Tax Return is filed after the due date, HMRC may apply penalties and could charge interest on any tax paid late. The exact consequences depend on how late the return is, whether tax is outstanding, and the company's history, so the position is specific to each case. If you think a return may be late, or you have received correspondence from HMRC about a missing return, it is usually best to act quickly: we can help you prepare the outstanding CT600, get the filing sorted, and explain what steps may be available to you.
