CT600 Tax Return Filing in Gravesend — Prepare and File Your Company Tax Return with HMRC

CT600 Tax Return Filing is how a UK limited company reports its Corporation Tax position to HMRC. It involves more than typing figures into an online form: the accounting profit shown in your accounts often needs to be adjusted before taxable profit, and therefore the Corporation Tax due, can be worked out. Our approach in Gravesend is to take the figures from your bookkeeping and accounts, review them for the tax adjustments that apply, prepare the Corporation Tax computation, and submit the CT600 to HMRC accurately and on time. It is important to be clear that a CT600 is not the same as statutory accounts filed with Companies House. Statutory accounts are a separate filing obligation with a different audience and a different format, and filing one does not discharge the other. Professional support gives you a clear, documented picture of your company’s tax position, removes the guesswork from the calculation, and lets you get on with running the business while the paperwork is handled properly.

 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 CT600, and What Does It Mean for a Micro-Entity Company?

There is no separate official “micro-entity CT600” form — the CT600 is the standard Company Tax Return used by UK companies to report their Corporation Tax position to HMRC, and a micro-entity company uses exactly the same return as any other company. What differs is the accounting side: a company preparing accounts under a micro-entity framework produces simpler statutory accounts, but those accounts still feed into the tax process. Where a company is within the charge to Corporation Tax, it may need to submit a Company Tax Return, and the figures from its accounting records and accounts are typically the starting point for the Corporation Tax computation. From there, adjustments may be required, so the taxable profit used for Corporation Tax can differ from the accounting profit shown in the accounts — common examples include disallowable expenses, capital allowances instead of depreciation, and items treated differently for tax than for accounting purposes. A micro-entity company is not automatically exempt simply because it prepares simpler accounts, and equally it is not automatically liable to pay Corporation Tax: whether any Corporation Tax is payable depends on the company’s own circumstances and taxable position. It is also worth separating two ideas that often get muddled — filing the CT600 and paying any Corporation Tax are distinct obligations, and submitting the return does not by itself settle the tax due. Finally, remember that the CT600 submitted to HMRC is separate from the statutory accounts filed with Companies House, and the figures used for tax may need adjusting even where the accounts themselves are prepared on a straightforward basis.

Let Us Take CT600 Tax Return Filing Off Your Desk

Preparing a Company Tax Return is rarely as simple as copying the profit figure from your accounts. Adjustments, allowances, disallowable costs and the distinction between accounting profit and taxable profit all have to be worked through before the CT600 can be completed accurately — and Corporation Tax records still need to be kept organised for HMRC. Micro Entity Accounts helps companies in Gravesend and across the UK with the practical side of this: CT600 preparation, Corporation Tax computation, a review of the tax adjustments relevant to your figures, and submission of the Company Tax Return to HMRC. If your accounts are also due at Companies House, we can make sure the two processes are handled as the separate obligations they are. The result is a clearer, better-supported tax position and less time spent wrestling with paperwork. Get in touch to discuss your CT600 Tax Return Filing requirements and we will talk you through the next steps.

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 formal Company Tax Return that a UK company submits to HMRC to report its Corporation Tax position for an accounting period. It brings together details of the company, the period covered, the company's tax calculations and the resulting Corporation Tax liability, along with the supporting computations and information HMRC expects. It is a tax return, not a set of accounts, and it is filed with HMRC rather than Companies House.

Is a CT600 different from statutory accounts?

Yes, and the distinction matters. Statutory accounts are prepared under an accounting framework and filed with Companies House as part of the company's public filing obligations. The CT600 is the tax return submitted to HMRC. They are separate documents, with separate purposes and separate recipients, and the figures used for tax may need adjusting away from the accounting figures, so the two will not always match line for line. Filing your accounts does not mean your CT600 has been filed, and vice versa.

What is the difference between a CT600 and a Corporation Tax computation?

The Corporation Tax computation is the working paper that starts from the accounting profit in the accounts and adjusts it to arrive at taxable profit, applying the tax rules that are relevant to the company's circumstances. The CT600 is the return form that reports the outcome of that process to HMRC. In practice the computation usually accompanies the return, which is why a CT600 without a properly reasoned computation can leave questions unanswered if HMRC reviews the figures.

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

There is no separate micro-entity CT600 — the same CT600 is used by companies generally. Whether a particular company needs to submit a Company Tax Return depends on its own circumstances and its Corporation Tax position, and preparing micro-entity accounts does not by itself remove that obligation. It is also worth being clear that a micro-entity company is not automatically liable to pay Corporation Tax simply because it is small; liability depends on the taxable position for the period. If you are unsure where your company stands, the sensible step is to have the position reviewed before assuming either way.

Can a company file its CT600 without filing its accounts?

The two are separate obligations owed to different bodies, and they are not dependent on one another in the way many directors assume. However, the CT600 still needs to be supported by accounts, computations and records that are consistent and complete, because the return is built on those figures. In practice, preparing the accounts first is the cleanest route to an accurate return, even though the Companies House filing itself is a distinct exercise.

What information is needed to prepare a CT600?

Typically you will need the company's accounting records and finalised accounts for the period, the trial balance or profit and loss detail, a breakdown of expenses so that disallowable items can be identified, details of fixed asset purchases and disposals, information on any other income, and any earlier-period losses, reliefs or figures carried forward that affect the current computation. Bank statements, invoices and payroll records help substantiate the numbers. The exact list depends on the company's activities and circumstances.

How is taxable profit calculated from accounting profit?

The starting point is usually the accounting profit shown in the accounts, but that is not automatically the taxable profit. Adjustments are made for items treated differently for tax purposes — for example, adding back expenditure that is not allowable for tax, replacing accounting depreciation with capital allowances, and accounting for income or expenditure that falls into a different period for tax. The result is the taxable profit, which is then used to determine the Corporation Tax position. Because the adjustments depend on the specific transactions, the same headline profit figure can lead to different taxable results for different companies.

Is filing a CT600 the same as paying Corporation Tax?

No. Filing the CT600 and paying any Corporation Tax that is due are two separate obligations, each with its own process. Submitting an accurate return does not in itself settle the tax, and the amount payable is determined by the figures in the return once the taxable profit has been calculated. It is worth understanding both elements of your company's position rather than treating the filing as the end of the matter.
