CT600 Tax Return Filing in Lechlade — 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 Lechlade can take the pressure off. The CT600 is the Company Tax Return itself — the form used to report your company’s income, allowable deductions and resulting Corporation Tax position to HMRC. It is a separate filing obligation from the statutory accounts you send to Companies House, even though the two are closely related and often prepared from the same underlying records. Our approach is built around accuracy and clarity: we review the accounting figures, consider where tax adjustments may be needed to arrive at taxable profit, prepare the Corporation Tax computation that supports the return, and submit the CT600 to HMRC on your behalf. That means fewer loose ends, a clearer picture of your company’s tax position, and the convenience of having the whole process handled by people who do this work regularly. Whether you are filing for the first time, catching up on overdue periods, or simply want your accounts and Corporation Tax filing dealt with together, we can help you approach your HMRC filing obligations with confidence.

 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 Apply to a Micro-Entity Company?

There is no separate official form called a “micro-entity CT600” — the CT600 is simply the standard Company Tax Return used by companies of all sizes to report their Corporation Tax position to HMRC. Where a company operates as a micro-entity, it may still have Corporation Tax obligations, and if HMRC requires a Company Tax Return, the company will ordinarily need to complete and submit a CT600 covering the relevant accounting period. It is important to understand that the CT600 is not the same thing as statutory accounts. Statutory accounts are prepared under an accounting framework and filed with Companies House, while the CT600 is a tax return submitted to HMRC. The two documents are related, but they serve different purposes and go to different authorities. In practice, a micro-entity’s accounting records and accounts often provide the starting point for the Corporation Tax calculation, but the figures usually need to be reviewed and adjusted before taxable profit is confirmed. Some items of income or expense are treated differently for tax than they are in the accounts, so taxable profit can differ from accounting profit. Equally, the fact that a company prepares micro-entity accounts, or uses a particular accounting framework such as FRS 105, does not by itself determine its Corporation Tax liability — the tax position depends on the company’s own circumstances, profits, reliefs and allowances. Preparing the accounts and filing the CT600 are therefore related but separate processes, and it is also worth remembering that filing a CT600 and paying any Corporation Tax due are two distinct obligations with their own timelines.

What is a CT600?

A CT600 is the form HMRC uses for a Company Tax Return in the UK. It is the mechanism by which a company reports its income, allowable deductions and Corporation Tax position for a given accounting period. The CT600 is submitted to HMRC, not to Companies House, and it is normally supported by a Corporation Tax computation that shows how taxable profit has been calculated from the company's accounting figures. The return also captures other information HMRC requires, such as details of the company, the period covered and any relevant reliefs or allowances claimed.

What is a Company Tax Return?

A Company Tax Return is the formal submission a company makes to HMRC to report its Corporation Tax position for an accounting period. The CT600 form is the core of that return, but the return as a whole usually includes the supporting tax computation and, depending on the circumstances, other schedules or supplementary pages. Filing a Company Tax Return is separate from filing statutory accounts with Companies House, and it is also separate from paying any Corporation Tax that may be due — the filing obligation and the payment obligation run on their own timelines.

Who needs to file a CT600?

Broadly speaking, a company needs to file a Company Tax Return when HMRC has issued a notice to deliver one, which commonly happens after a company is incorporated or begins trading. Some companies may be in a position where no Corporation Tax is ultimately payable, but that does not automatically remove the requirement to file if HMRC has asked for a return. Because the obligation depends on the company's own circumstances and on what HMRC has requested, it is worth checking your position rather than assuming a return is or is not needed.

Is a CT600 different from statutory accounts?

Yes. Statutory accounts are prepared under an accounting framework and filed with Companies House, where they become part of the public record. A CT600 is a tax return submitted to HMRC to report the company's Corporation Tax position. They are prepared from much of the same information, and the accounts often form the starting point for the tax work, but they are distinct documents with different audiences and different purposes. Filing one does not satisfy the obligation to file the other.

Is a CT600 different from a Corporation Tax computation?

They are closely connected but not the same thing. The Corporation Tax computation is the working document that starts with the company's accounting profit and applies the necessary tax adjustments to arrive at taxable profit and the resulting Corporation Tax liability. The CT600 is the return form on which those results are reported to HMRC. In practice the computation supports the figures entered on the CT600, which is why careful preparation of both matters.

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

There is no separate micro-entity version of the CT600 — the same form is used. A company that qualifies as a micro-entity may still have Corporation Tax obligations, and if HMRC has issued a notice requiring a Company Tax Return, the company will normally need to complete and submit a CT600 for the relevant period. It does not automatically follow that Corporation Tax will be payable; that depends on the company's taxable position after adjustments, reliefs and allowances. Preparing micro-entity accounts and filing a CT600 are related but separate processes.

What information is needed to prepare a CT600?

As a starting point, you will typically need the company's accounting records and finalised accounts for the period, details of income and expenditure, information on capital expenditure and any claims for reliefs or allowances, and the company's registration details. Where the company has more complex affairs, additional information may be needed. It also helps to have a clear record of any items that may be treated differently for tax than in the accounts, since these drive the adjustments between accounting profit and taxable profit.

Is filing a CT600 the same as paying Corporation Tax?

No. Filing the CT600 is about reporting the company's Corporation Tax position to HMRC, while paying Corporation Tax is a separate obligation with its own due date. A company can submit its return and still have tax to pay, or submit a return showing no tax due while still needing to meet the filing requirement. It is important to treat the two as distinct so that neither is overlooked, and to keep your records organised so both can be dealt with properly.
