CT600 Tax Return Filing in Saffron Walden – Preparing and Filing Your Company Tax Return with HMRC

If your company needs to report its Corporation Tax position to HMRC, CT600 Tax Return Filing is the process that gets it done. We help companies in Saffron Walden and the surrounding area prepare an accurate Company Tax Return, starting with a clear review of the accounting figures, the tax adjustments that may be needed, and the supporting records behind them. The CT600 itself is a tax return submitted to HMRC and is a separate obligation from the statutory accounts filed with Companies House, even though the two draw on much of the same underlying information. That distinction matters: accounts are prepared for filing at Companies House under the relevant accounting framework, while the CT600 reports taxable profit and the resulting Corporation Tax position to HMRC. Working with a professional team takes the guesswork out of the process, keeps your records organised, and gives you a straightforward path from bookkeeping through to submission, with clear communication at each stage and transparent pricing agreed up front.

 Trustindex verifies that the original source of the review is Google. I worked with Accotx on a HMRC reclaim and overall, they did ultimately deliver on their promise, which I appreciate. The process did take longer than any of us expected, partly due to external delays with the tax authorities, and partly because there were some hiccups in communication and follow-up. However, despite those challenges, they stayed professional and stuck to the original agreed terms. If you’re considering using them, be prepared to stay in regular contact to keep things moving along. They are absolutely capable, have the expertise and willing to work with you, and overall  improving their services over time. I would certainly return for any future needs.

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

Throughout the process, he was incredibly patient, took the time to answer all of my questions, and explained everything clearly. He guided me through each step and helped rectify issues that had built up over time, making what felt like an overwhelming situation much more manageable.

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 the standard Company Tax Return used to report a company’s Corporation Tax position to HMRC, and it applies to companies generally, whatever their size. What changes for a micro-entity company is not the return itself but the accounting framework used to prepare its statutory accounts and the level of detail those accounts contain. A micro-entity company can still have Corporation Tax obligations: where HMRC requires a Company Tax Return, the company needs to prepare and submit one, and its accounting records and accounts usually form the starting point for the figures reported. It is important to separate three things here. First, the statutory accounts, which are filed with Companies House. Second, the CT600, which is the Company Tax Return filed with HMRC. Third, the Corporation Tax computation, which may adjust the accounting figures to arrive at taxable profit. Taxable profit can differ from accounting profit because the tax rules may treat certain items differently — for example, some expenses may be disallowed, or capital allowances may be claimed instead of a depreciation charge. Those adjustments are made in the Corporation Tax computation, not in the accounts themselves, and the framework a company uses to prepare its accounts does not by itself determine its Corporation Tax liability. It is also worth being clear that submitting a CT600 and paying Corporation Tax are separate obligations: the return reports the position, while payment is a distinct matter, and whether any Corporation Tax is actually payable depends on the company’s own circumstances and taxable position.

What is a CT600?

A CT600 is the Company Tax Return form used to report a company's Corporation Tax position to HMRC. It sets out figures drawn from the company's accounts and records, alongside the tax adjustments and calculations that support the taxable profit reported. In practice, most companies file their CT600 online together with a Corporation Tax computation and, where required, a copy of the statutory accounts. The CT600 is a tax return, so it is a different document from the statutory accounts a company files at Companies House.

Is a CT600 different from the statutory accounts?

Yes, they are separate documents with separate purposes and separate filing destinations. Statutory accounts are prepared and filed at Companies House and show the company's financial position and performance under the applicable accounting framework. The CT600 is a tax return submitted to HMRC and reports the company's Corporation Tax position. Even though both are built on the same underlying bookkeeping, the figures can differ once tax adjustments are applied, which is why the two should not be treated as interchangeable.

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

It depends on the company's circumstances. Being a micro-entity affects how the statutory accounts are prepared, but it does not remove Corporation Tax obligations. Where HMRC requires a Company Tax Return, the company needs to prepare and submit one, and the return must be filed even if no Corporation Tax turns out to be payable. It is also worth remembering that filing the CT600 and paying any Corporation Tax due are two separate obligations, so submitting the return does not by itself settle a tax liability.

Can a company file its CT600 without filing its accounts?

The CT600 is filed with HMRC, while statutory accounts are filed with Companies House, so the two filings are made separately and on their own timelines. Companies House accounts must normally be delivered in line with the company's filing obligations, and accounts may also need to accompany the Company Tax Return where HMRC requires this. Because the position varies between companies, it is sensible to plan both filings together so that the accounts, the computation and the CT600 remain consistent with each other.

Is a CT600 the same as a Corporation Tax computation?

No. The CT600 is the return that reports the company's Corporation Tax position to HMRC, while the Corporation Tax computation is the working paper that shows how taxable profit has been arrived at. The computation starts from the accounting profit in the accounts and then makes the adjustments the tax rules require, such as adding back disallowed expenses or reflecting capital allowances. The resulting taxable profit and the related tax position are then reported on the CT600, which is why a computation usually accompanies the return.

How is taxable profit calculated from accounting profit?

Taxable profit is calculated by taking the accounting profit shown in the company's accounts and adjusting it for items that the tax rules treat differently. Common adjustments include adding back expenses that are not allowable for tax and replacing accounting depreciation with any capital allowances that are available. Depending on the company, other reliefs or adjustments may also apply. The figures, and therefore the tax position, depend on the company's individual circumstances, so the computation should always be prepared from the actual records rather than assumed.

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

Yes. A company can appoint an accountant or tax adviser to prepare the Corporation Tax computation and CT600 and to submit the Company Tax Return to HMRC on its behalf. The company remains responsible for the accuracy of what is filed, so it is important to hand over complete and reliable records — sales, expenses, payroll information, asset purchases, and any other supporting documents. Keeping those records organised through the year makes the CT600 Tax Return Filing process far smoother when the time comes.

What information is needed to prepare a CT600?

The main inputs are the company's accounting records for the period and the accounts prepared from them, since these give the starting point for the tax calculation. It also helps to have details of any asset purchases or disposals, payroll and pension costs, loan interest, and any income or expenses that may need special tax treatment. Your accountant will normally ask for supporting documentation for anything unusual. If any information is missing, it can usually be identified early in the process, which is one advantage of planning the CT600 Tax Return Filing ahead of the deadline rather than leaving it to the last moment.
