CT600 Tax Return Filing in Leatherhead – Prepare and File Your Company Tax Return with HMRC

CT600 Tax Return Filing is the process of preparing and submitting a company’s Company Tax Return to HMRC so that its Corporation Tax position is reported accurately. If your company is based in Leatherhead or the surrounding Surrey area, professional support with CT600 Tax Return Filing means the figures behind your return are properly reviewed, the Corporation Tax computation is put together with care, and the return is filed through HMRC’s online service on your behalf. It is important to understand that a CT600 is not the same as your statutory accounts. Statutory accounts are prepared and filed separately with Companies House, while the CT600 is a tax return submitted to HMRC. The two are connected because the accounts usually form the starting point for the Corporation Tax calculation, but they serve different purposes and follow different rules. Good CT600 Tax Return Filing brings accuracy and clarity: your accounting profit is reviewed, any tax adjustments are identified, and your taxable profit and Corporation Tax position are set out in a way that is easy to follow. It also brings convenience, because the administrative work of gathering information, checking disclosures and dealing with HMRC’s filing requirements is handled for you, leaving you free to run the business.

 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 a CT600 Means for Companies Operating as Micro-Entities in Leatherhead

There is no separate official “micro-entity CT600” form. A CT600 is the standard Company Tax Return used by companies to report their Corporation Tax position to HMRC, and it is the same return whether a company prepares full statutory accounts or takes advantage of the simpler reporting options available to smaller companies. A company that meets the criteria to operate as a micro-entity may still have Corporation Tax obligations, and where HMRC requires a Company Tax Return, that return still needs to be prepared and filed. This is distinct from the company’s statutory accounts, which are a separate filing obligation and, depending on the company’s circumstances, may be filed with Companies House. Where a CT600 is required, the company’s accounting records and accounts often provide the starting point for the Corporation Tax calculation, but they are not the end of the process. Accounting profit and taxable profit can differ, because Corporation Tax calculations may require adjustments — for example, to add back certain expenses that are not allowable for tax, or to account for items treated differently under tax rules. It is also worth stressing that filing a CT600 and paying Corporation Tax are two separate obligations: submitting the return reports the position, while any liability that arises depends on the company’s own taxable profits and circumstances. Not every micro-entity will owe Corporation Tax, and not every company will be required to file a return in the same way.

Let Us Handle Your CT600 Tax Return Filing in Leatherhead

Preparing a Company Tax Return can quickly become complicated.

Add to that the record-keeping, the HMRC filing requirements and the need to keep everything separate from your statutory accounts, and it is easy to see why many directors would rather hand the whole exercise to someone who does it regularly.

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 name of the Company Tax Return form used to report a company's Corporation Tax position to HMRC. It brings together details of the company's income and expenditure, the tax adjustments made to the accounting figures, and the resulting taxable profit, together with any Corporation Tax due or repayable. In practice, the CT600 is usually submitted online and is supported by a Corporation Tax computation and, in most cases, a copy of the statutory accounts. It is a tax document, not a Companies House filing.

Who needs to file a CT600?

A company needs to file a Company Tax Return when HMRC has issued a notice to deliver one, which is commonly sent shortly after the company is incorporated or begins trading. Even a company that has made no profit, or no taxable profit at all, may still be required to submit a return to confirm that position. Because the requirement depends on HMRC's notice and the company's own circumstances, it is always worth checking your position rather than assuming a return is or is not needed.

Is a CT600 different from statutory accounts?

Yes, they are two separate documents with two separate purposes. Statutory accounts are the company's formal financial statements, prepared in line with the applicable accounting framework and filed with Companies House where required. The CT600 is a Company Tax Return submitted to HMRC. The figures in the accounts are often used as the starting point for the tax calculation, but the accounts themselves do not report a tax liability to HMRC in the way the CT600 does.

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

There is no separate CT600 for micro-entities. If a company operates as a micro-entity, it may still be within the Corporation Tax system and may still be required to file a Company Tax Return where HMRC has issued a notice to deliver one. Preparing simpler accounts under a micro-entity framework does not remove the obligation to report to HMRC, and it does not automatically determine what Corporation Tax, if any, is payable. Whether a return is required, and whether any tax is due, depends on the company's circumstances.

What is the difference between a CT600 and a Corporation Tax computation?

The Corporation Tax computation is the working paper that starts with the company's accounting profit and adjusts it to arrive at the taxable profit, explaining each adjustment along the way. The CT600 is the return form that reports the outcome of that work to HMRC. In other words, the computation is the calculation and the CT600 is the submission. In many cases the computation is filed alongside the CT600 as supporting information.

How is taxable profit worked out from accounting profit?

The starting point is normally the profit shown in the company's accounts. From there, the calculation may need adjustments — for example, adding back expenses that are not allowable for tax purposes, deducting items that are treated differently under tax rules, or allowing capital allowances in place of depreciation. The result is the taxable profit, which is the figure used to determine the Corporation Tax position. Because the adjustments depend on the specific transactions and records, taxable profit often differs from accounting profit.

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 position is. Paying Corporation Tax is a separate obligation that arises only where the company has a liability based on its taxable profits. A company can file a return showing no tax payable, and a company with tax to pay still needs to settle that liability separately, usually by a different deadline. Keeping filing and payment timings distinct is important.

What happens if a company files its CT600 late, and can someone file it on the company's behalf?

If a return is filed after the date HMRC requires it, HMRC can apply penalties and may also charge interest on any tax paid late; the amount depends on how late the return is and on HMRC's published rules, so the specific consequences vary. As for who files it, a company can authorise an accountant or agent to prepare and submit the CT600 on its behalf, which is a common arrangement — many directors find it helpful to have the accounts data, the tax adjustments and the return itself handled by one consistent process.
