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

Our CT600 Tax Return Filing service in Loanhead helps limited companies pull together their Corporation Tax position and submit a Company Tax Return to HMRC with confidence. We work through your accounting records, review the tax adjustments that turn accounting profit into taxable profit, and prepare the CT600 so the figures reported to HMRC are accurate and supported. It is worth being clear from the outset that a CT600 is not the same as your statutory accounts. Statutory accounts are a separate filing obligation, normally submitted to Companies House, and the two documents serve different purposes even where they draw on the same underlying bookkeeping. Whether you are a director filing for the first time or an established company looking for a straightforward, well-organised return, we aim to make the process clear and convenient, with transparent pricing and practical support at every stage.

 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.

I'm very pleased with the service I've received and truly appreciate his support. If you need help with your accounts or taxes, I would highly recommend Imran.

What Is a Micro-Entity CT600 and How Does It Fit With CT600 Tax Return Filing?

There is no separate official “micro-entity CT600” form. The CT600 is the form HMRC uses for a Company Tax Return, and it is the same core return used by companies of all sizes. What differs for a micro-entity company is the accounting side: a company that qualifies as a micro-entity may prepare and file micro-entity accounts under a simpler reporting framework, but that does not change the fact that the company may still have Corporation Tax obligations. Where HMRC requires a return, the company needs to submit a Company Tax Return (CT600) covering the relevant accounting period. The CT600 is separate from the statutory accounts filed with Companies House, and it is also separate from the Corporation Tax computation that usually sits behind it. The accounting figures in your accounts are the starting point, but taxable profit is not automatically the same as accounting profit. Corporation Tax calculations may require adjustments — for example for disallowable expenditure, capital allowances or other tax-specific treatments — before the taxable profit and any Corporation Tax liability are confirmed. Equally, not every micro-entity will owe Corporation Tax; whether tax is payable depends on the company’s own circumstances and taxable position. Filing the CT600 and paying any Corporation Tax due are also two distinct obligations, so it is worth keeping both in view.

3 months late	A further £100
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.

Make CT600 Tax Return Filing in Loanhead Straightforward

We can prepare your CT600, build and review the Corporation Tax computation and the tax adjustments behind it, and handle the HMRC filing on your behalf, so you have a clear record of what has been submitted and why.

What is a CT600 and what is it used for?

A CT600 is the form used to submit a Company Tax Return to HMRC. It reports the company's Corporation Tax position for an accounting period, including the figures that support the taxable profit calculation and any tax due. The CT600 is an HMRC document, which is why it is completely separate from anything you file at Companies House. In practice, the CT600 is usually prepared alongside a Corporation Tax computation that shows how the company's accounting profit has been adjusted to arrive at taxable profit.

Who needs to file a CT600 Tax Return with HMRC?

It depends on the company's circumstances. A company that is within the charge to Corporation Tax will generally need to notify HMRC and, where a return is required, submit a Company Tax Return for the relevant accounting period. Dormant or non-trading companies may have different requirements, and some companies are asked by HMRC to file a return even when no tax is expected to be payable. Because the position varies, it is sensible to check your company's own situation rather than assuming one rule applies to everyone — we can help you work out what is required.

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

Yes, they are separate documents with separate purposes and separate destinations. Statutory accounts are prepared for the company's members and filed at Companies House under the applicable reporting framework. A CT600 is a Company Tax Return submitted to HMRC and deals with Corporation Tax. The two overlap in that the accounts figures are normally the starting point for the tax computation, but they are not interchangeable, and filing one does not satisfy the obligation to deal with the other.

Is a CT600 the same as a Corporation Tax computation?

No. The computation is the working paper that starts with the company's accounting profit and makes the tax adjustments needed to arrive at taxable profit and the resulting Corporation Tax figure. The CT600 is the return form on which those results are reported to HMRC. You can think of the computation as the explanation and the CT600 as the submission — both usually need to be prepared, and they need to agree with each other.

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

A micro-entity company may still need to file a Company Tax Return, even though it can prepare simpler micro-entity accounts. Qualifying as a micro-entity affects how the accounts are prepared and filed; it does not by itself determine whether the company has a Corporation Tax filing obligation, and it does not determine the company's Corporation Tax liability. It is also important not to assume that every micro-entity owes Corporation Tax — whether tax is payable depends on the company's taxable position and its own circumstances.

What information is needed to prepare a CT600?

Typically we need the company's accounting records and finalised accounts for the period, details of income and expenditure, any capital purchases or disposals, information about expenses that may not be deductible for tax purposes, and records of any tax already paid or credits to be claimed. Company and accounting period details are needed as well. The exact list depends on the nature of the business, and where something is missing we will tell you what is required rather than guessing at figures.

How is taxable profit calculated from accounting profit?

Taxable profit is not simply the profit shown in the accounts. The calculation starts with accounting profit and then applies the tax adjustments that are relevant to the company. These can include adding back expenditure that is not allowable for tax, deducting allowable items that were not treated as expenses in the accounts, and dealing with capital allowances and other tax-specific treatments. Once those adjustments are made, the taxable profit and the Corporation Tax position can be determined and reported on the CT600.

Is filing a CT600 the same as paying Corporation Tax?

No — filing and payment are separate obligations. The CT600 reports the company's Corporation Tax position and is submitted to HMRC, while payment of any Corporation Tax due is made separately according to HMRC's rules and the company's own payment schedule. A company may need to submit a return even where no tax is payable, and a company with tax to pay still needs to deal with the return itself. Keeping both in view avoids unnecessary surprises.
