CT600 Tax Return Filing in Ilchester: Prepare and File Your Company Tax Return with HMRC

CT600 Tax Return Filing in Ilchester is the process of preparing your company’s Company Tax Return and submitting it to HMRC so your Corporation Tax position is reported accurately and on time. It is not the same as filing statutory accounts with Companies House — those accounts present your company’s financial results to the public register, while the CT600 reports your company’s Corporation Tax position to HMRC, using figures that may need adjusting before taxable profit is agreed. Professional CT600 Tax Return Filing brings clarity to that process: your accounting records are reviewed, the Corporation Tax computation is prepared, tax adjustments are considered, and the completed Company Tax Return is filed through the correct HMRC channel. You get a straightforward explanation of what has been submitted and why, without needing to become an expert in Corporation Tax terminology. If you would rather spend your time running the business than working through the detail of a Corporation Tax Return, our team can handle the preparation, the computation and the filing, and keep your Corporation Tax records organised along the way.

 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 Micro-Entity CT600 and How Does It Relate to CT600 Tax Return Filing?

There is no separate official “micro-entity CT600” form — the CT600 is HMRC’s Company Tax Return, and the same return is used by companies of different sizes, including companies that meet the micro-entity criteria for accounting purposes. What changes for a micro-entity is the accounting framework it uses to prepare its accounts, not the existence of a special Corporation Tax Return. A company that qualifies as a micro-entity may still have Corporation Tax obligations, and where HMRC requires a Company Tax Return, that company will need to complete and submit a CT600. The CT600 is separate from the statutory accounts, which are filed with Companies House under a different regime, although the two are connected: the figures in your accounts and accounting records usually form the starting point for the Corporation Tax calculation. Taxable profit is not automatically the same as accounting profit. Corporation Tax computations commonly require adjustments — for example, adding back certain disallowable expenses or accounting for items treated differently for tax — before taxable profit and any Corporation Tax liability can be determined. Preparing accounts and filing a Company Tax Return are therefore related but separate processes, and filing a CT600 is not the same as paying Corporation Tax; the filing obligation and the payment obligation are handled separately. Not every micro-entity will owe Corporation Tax, because whether tax is payable depends on the company’s own circumstances and taxable position, and whether a return is required at all is something HMRC will confirm based on those circumstances.

6 months late	HMRC estimates your tax bill and adds 10% of the unpaid tax
12 months late	A further 10% of any unpaid tax

Penalty levels are set by Companies House and may change. Separate HMRC penalties and interest apply to a late Corporation Tax return and unpaid tax. Check the updated guide here.

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 form HMRC uses for a Company Tax Return — the return a company submits to report its Corporation Tax position. When people refer to CT600 Tax Return Filing, they mean completing that return and submitting it to HMRC, usually alongside a Corporation Tax computation and, where relevant, a copy of the statutory accounts. The CT600 pulls together information about the company's income, allowable deductions and the resulting Corporation Tax position for the accounting period covered by the return.

Is a CT600 the same as a Corporation Tax computation?

No. They work together, but they are different documents. The Corporation Tax computation is the working paper that starts from your accounting profit and applies the tax adjustments needed to arrive at taxable profit and the associated Corporation Tax liability. The CT600 is the actual return submitted to HMRC, and it reports the figures that flow out of that computation. A good CT600 Tax Return Filing service will therefore prepare the computation first and use it to complete the return accurately.

Is a CT600 different from statutory accounts?

Yes, and the distinction matters. Statutory accounts are prepared under an accounting framework and filed at Companies House, where they become part of the public record. A CT600 is a Company Tax Return submitted to HMRC for Corporation Tax purposes. The two are prepared for different audiences and serve different legal obligations. That said, your accounts and accounting records are normally the starting point for the Corporation Tax computation that supports the CT600, which is why keeping clear records makes both filings easier.

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

A company that meets the micro-entity criteria for accounting purposes may still have Corporation Tax obligations, and where HMRC requires a Company Tax Return, that company will need to file a CT600. There is no separate micro-entity version of the CT600 — it is the same Company Tax Return used across companies, with the size of the business affecting the accounts framework rather than the existence of the return. Not every micro-entity will owe Corporation Tax, because whether tax is payable depends on the company's taxable position and circumstances, and filing a return is separate from paying any tax due.

Can a company file its CT600 without filing its accounts?

Filing a CT600 and filing statutory accounts are two separate obligations with different recipients, and meeting one does not automatically satisfy the other. The Company Tax Return is submitted to HMRC, while statutory accounts are filed with Companies House. In practice the figures are closely linked, because the Corporation Tax computation usually begins with the results shown in the accounts. Because requirements can vary depending on the company's circumstances, it is worth checking your position, particularly if you are filing for the first time or have changed your accounting framework.

How is taxable profit calculated from accounting profit?

Taxable profit is not simply the profit shown in your accounts. The Corporation Tax computation normally starts with the accounting profit and then applies adjustments — for example, adding back expenses that are not allowable for tax purposes, or accounting for income and deductions that are treated differently under tax rules. Once those adjustments are made, the result is the taxable profit on which Corporation Tax is calculated, if any is due. The nature and size of the adjustments depend entirely on the company's own transactions and circumstances.

Is filing a CT600 the same as paying Corporation Tax?

No — these are separate obligations. CT600 Tax Return Filing is about reporting your company's Corporation Tax position to HMRC, whereas paying Corporation Tax is about settling any liability that arises from that position. A company can have a filing obligation even where no tax is payable, and a company with tax to pay still needs to submit the return. It is important to keep both the filing and the payment in view, and to keep Corporation Tax records organised throughout the year rather than scrambling at the last moment.

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

Yes. A company can appoint an accountant or tax agent to prepare the Corporation Tax computation and the CT600 and to submit the Company Tax Return to HMRC on its behalf, with the company remaining responsible for the accuracy of the information provided. This is often the simplest route for directors who want the Corporation Tax position reviewed properly without working through the technical detail themselves. If you are considering CT600 Tax Return Filing support in Ilchester, it helps to have your accounting records, details of income and expenses, and any previous returns to hand so the work can begin promptly.
