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

If your company is based in Lancing and needs to report its Corporation Tax position to HMRC, CT600 Tax Return Filing is the process that gets it done. The CT600 is the Company Tax Return — a formal submission to HMRC that sets out your company’s income, allowable deductions and the resulting Corporation Tax position for an accounting period. It is not the same as the statutory accounts you file with Companies House, and it is not a Confirmation Statement or a VAT Return. Professional CT600 Tax Return Filing brings the whole process together: reviewing your accounting records, preparing the Corporation Tax computation with the adjustments needed to move from accounting profit to taxable profit, and submitting the completed Company Tax Return to HMRC on your behalf. For directors in Lancing, that means less time spent wrestling with HMRC’s filing system, clearer records supporting the figures reported, and the confidence of knowing the return has been prepared with care by people who work with Company Tax Returns every day.

 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.

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 Micro-Entity CT600 and How Does CT600 Tax Return Filing Work?

A micro-entity is a company that meets the size criteria for the smallest category of company under UK accounting rules, which means its directors may be able to prepare accounts using a simplified framework. What a micro-entity does not get is a separate, special HMRC form — there is no distinct official “micro-entity CT600”. A company that qualifies as a micro-entity still uses the same CT600 to report its Corporation Tax position, where HMRC has issued a notice to deliver a Company Tax Return or the company otherwise needs to file one. Whether a micro-entity actually owes Corporation Tax depends entirely on its own circumstances and taxable position: the filing obligation and the payment of Corporation Tax are separate matters, and a company can have a filing requirement without any tax being payable. It is also important not to confuse CT600 Tax Return Filing with statutory accounts — the accounts filed with Companies House and the Company Tax Return submitted to HMRC are two different documents serving two different purposes. That said, the accounting figures in those accounts are usually the starting point for the Corporation Tax calculation. Micro-entity accounts prepared under a framework such as FRS 105 do not by themselves determine Corporation Tax liability, because taxable profit can differ from accounting profit. The Corporation Tax computation may need adjustments — for example, adding back disallowable expenditure, removing depreciation and claiming capital allowances instead, or bringing in losses and reliefs. Accounts preparation and Corporation Tax filing are therefore related but separate processes, and getting both right is what makes CT600 Tax Return Filing worthwhile.

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 used to submit a Company Tax Return to HMRC. It reports your company's income, allowable expenses, allowances, reliefs and the resulting Corporation Tax position for a specific accounting period. Depending on the company's circumstances, additional supplementary pages may be required alongside the main form. Submitting a CT600 to HMRC is a separate obligation from filing statutory accounts with Companies House — the two serve different purposes and go to different bodies, even though the underlying figures often overlap.

Is a CT600 different from statutory accounts?

Yes, they are distinct documents. Statutory accounts are prepared under an accounting framework and filed at Companies House, where they become part of the public record and give shareholders and other readers a view of the company's financial performance and position. The CT600 is a tax return submitted to HMRC, and it focuses on the company's Corporation Tax position rather than on general financial reporting. The accounts usually provide the starting figures, but the return is shaped by tax rules, which is why a Corporation Tax computation normally sits behind it.

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

It depends on the company's circumstances. If HMRC has issued a notice to deliver a Company Tax Return, the company must file one — and that applies whether or not it qualifies as a micro-entity and whether or not any Corporation Tax is actually payable. Micro-entity status affects how the statutory accounts may be prepared, not whether a Company Tax Return is required. Some companies will not need to file a return in a given period, so it is worth checking your position rather than assuming either way.

Is a CT600 the same as a Corporation Tax computation?

No. The Corporation Tax computation is the working paper that starts with the accounting profit shown in the accounts and adjusts it to arrive at the taxable profit, applying the relevant tax rules, reliefs and allowances. The CT600 is the actual return form delivered to HMRC that reports the outcome. The computation supports and explains the figures entered on the return, so both are needed, but they are not the same thing.

How is taxable profit calculated from accounting profit?

The calculation normally begins with the accounting profit for the period and then applies tax adjustments. Expenditure that is not allowable for tax purposes is typically added back, income that is treated differently for tax is dealt with separately, and depreciation is usually replaced with capital allowances on qualifying assets. Losses brought forward, reliefs and other adjustments may also come into play. Because the adjustments depend on the company's own transactions and circumstances, taxable profit can end up higher or lower than the accounting profit.

Is filing a CT600 the same as paying Corporation Tax?

No, these are two separate obligations. Filing the CT600 is about delivering the Company Tax Return and reporting the company's Corporation Tax position to HMRC. Paying Corporation Tax is a separate matter with its own arrangements and timing. A company can file a return showing no liability at all, and equally a company can have tax to pay regardless of when the return itself is submitted. It is worth treating the two as distinct tasks so neither is overlooked.

What information is needed to prepare a CT600?

Typically you will need the company's accounting records for the period, a trial balance or draft accounts, details of income and expenditure, information on fixed asset additions and disposals, capital allowance workings, losses brought forward, and details of any reliefs being claimed. The company's Unique Taxpayer Reference, the accounting period dates and previous returns are also useful. Well-organised records make the preparation smoother and make it easier to support the figures reported if HMRC raises questions later.

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

Yes. A company can appoint an accountant or tax agent to prepare the Corporation Tax computation and submit the Company Tax Return to HMRC on its behalf. The agent can also be authorised to deal with HMRC correspondence about the return. The company itself remains responsible for the accuracy of what is submitted, which is why a proper review of the figures and supporting records matters before anything is filed.
