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

CT600 Tax Return Filing in Ilkeston gives your company a clear, professionally supported way to report its Corporation Tax position to HMRC. We work through your accounting records for the period, identify the tax adjustments that may be needed, calculate the taxable profit and prepare and submit the Company Tax Return on your behalf. It is worth being clear from the outset that a CT600 is a separate filing obligation from the statutory accounts you send to Companies House, and from your Confirmation Statement, VAT Returns and other company filings — they serve different purposes and go to different bodies. Working with a professional team helps keep your figures consistent, reduces unnecessary back-and-forth with HMRC and keeps your filing responsibilities under control, so the whole process is accurate, clearly explained and as convenient as possible.

He helped me sort out a very complicated backlog of accounts and prepared my overdue tax returns with professionalism and attention to detail.

 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 Does a Micro-Entity CT600 Mean for Your Company?

If your company qualifies as a micro-entity, it may still have Corporation Tax obligations — and where HMRC requires it, that means submitting a Company Tax Return, which is prepared on the CT600. There is no separate official “micro-entity CT600” form: the CT600 is the same Company Tax Return used by companies generally, and what differs for a micro-entity is the way the underlying accounts are prepared and the options available under the applicable accounting framework, not the return itself. The CT600 is also not the same thing as your statutory accounts. Those accounts are prepared and filed under the relevant company law regime, while the CT600 is submitted to HMRC as part of your CT600 Tax Return Filing. In Ilkeston and across the UK, the starting point is usually the company’s accounting records, but the figures in the accounts are not automatically the figures used for tax. The Corporation Tax calculation may require adjustments — for example adding back disallowable expenditure, claiming capital allowances and dealing with other timing differences — so the taxable profit reported can differ from the accounting profit shown in the accounts. Whether a micro-entity actually owes Corporation Tax depends on its own circumstances and taxable position, and a company with no tax to pay may still have a filing obligation. Filing the return and paying any Corporation Tax due are also two separate obligations, so a submitted CT600 does not by itself mean the tax has been settled.

Let Us Take Care of Your CT600 Tax Return Filing in Ilkeston

The figures in your accounts rarely tell the whole story, and turning them into a Corporation Tax computation — with the adjustments, allowances and disclosures a Company Tax Return calls for — is often where the real time disappears. Keeping a clean record of how taxable profit was arrived at matters just as much as submitting the return itself, particularly if HMRC later asks questions. Micro Entity Accounts can take that work off your desk: we prepare the CT600, review the tax adjustments, set out a clear Corporation Tax computation and complete your CT600 Tax Return Filing with HMRC, so you have a properly documented trail behind the numbers. Get in touch to talk through your accounting period and see how straightforward the process can be.

Micro-Entity CT600 FAQs

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 HMRC uses for a Company Tax Return. It summarises a company's income, profits, gains, deductions, allowances and reliefs for a specific accounting period and sets out the resulting Corporation Tax position. It is submitted electronically to HMRC rather than to Companies House, and it normally sits alongside a Corporation Tax computation that shows how the figures were arrived at. The CT600 is the standard return used by companies generally — it is not a niche form reserved for any particular size of company.

Who needs to file a CT600?

A CT600 is filed by companies and other organisations that are within the scope of Corporation Tax. In practice, HMRC will normally issue a notice requiring a Company Tax Return, and the obligation follows from that notice and from the company's own circumstances rather than from its size. Dormant or non-trading companies can have different or reduced reporting requirements, so the position is not identical for every business. If you are unsure whether your company needs to file, it is worth checking rather than assuming. An accountant or tax agent can prepare and submit a CT600 on a company's behalf through HMRC's online services, which is how much of our CT600 Tax Return Filing work is carried out.

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

Yes — they are two separate documents with two separate purposes. Statutory accounts are prepared under the applicable accounting framework and filed at Companies House as part of the public record. The CT600 is a tax return submitted to HMRC to report the company's Corporation Tax position for an accounting period. The two are closely related because they both draw on the same underlying accounting records, but the figures are not always identical, and filing one does not discharge the obligation to file the other. Deadlines and formats differ too, so it is best to treat them as distinct tasks.

Is a CT600 different from a Corporation Tax computation?

They are related but not the same thing. The Corporation Tax computation is the supporting calculation that starts with the accounting profit in the accounts and adjusts it to arrive at the taxable profit and the Corporation Tax figure. The CT600 is the actual return that carries the summary figures to HMRC. In practice the two are usually prepared together, because the boxes on the return need to reflect the computation, and a clear computation is what allows the figures on the return to be explained and checked later.

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

It can do. Micro-entity status affects how the statutory accounts are prepared; it does not automatically remove a company from the Corporation Tax system. Where a company is within the scope of Corporation Tax and HMRC requires a return, a CT600 will normally be needed, even if the company has no Corporation Tax to pay for that period. Equally, the accounting framework a company uses does not by itself decide its Corporation Tax liability — that depends on the company's taxable profits, income and reliefs, which is why a proper computation matters.

What information is needed to prepare a CT600?

Typically you will need the company's accounting records for the period, including sales and purchase records, bank statements, invoices, payroll and subcontractor information, details of fixed asset additions and disposals, other income received, and any expenses you want taken into account. It also helps to have the previous year's return and computation, any brought-forward losses, details of any HMRC correspondence, and the company's Unique Taxpayer Reference and registration details. Accurate accounting period dates are essential, because the return is prepared for a specific period.

How is taxable profit calculated from accounting profit?

The starting point is usually the accounting profit shown in the company's accounts. From there, the Corporation Tax computation adds back items that are not allowable for tax, such as depreciation and certain disallowable expenses, and deducts items that are allowable but not yet reflected in the accounts, such as capital allowances, along with reliefs and any brought-forward losses. The result is the taxable profit, which is then used to work out the Corporation Tax position. Because of these adjustments, the taxable profit can be higher or lower than the accounting profit, and the difference is one of the main reasons a computation is prepared alongside the return.

Is filing a CT600 the same as paying Corporation Tax?

No. Filing the return and paying any Corporation Tax due are separate obligations with separate timetables. Submitting a CT600 tells HMRC what the company's position is; it does not automatically settle the liability, and in some cases Corporation Tax is payable before the return is filed. If a company has nothing to pay, it may still need to file, and if it has tax to pay, the filing does not remove the requirement to make payment. It is worth planning for both parts of the process rather than treating them as one step.
