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

CT600 Tax Return Filing in Inverurie is the process of preparing and submitting your company’s Company Tax Return to HMRC, reporting its Corporation Tax position for the accounting period. We work with directors and business owners to bring together the figures from your accounting records, review the tax adjustments that may be needed to arrive at taxable profit, and prepare and file the CT600 with HMRC. It is important to understand that a CT600 is not the same as your statutory accounts filed with Companies House — the two are separate obligations, even though they often draw on the same underlying figures. Our role is to make that process clearer, more accurate and far less time-consuming, so you can meet your Corporation Tax reporting responsibilities with confidence rather than guesswork.

 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 Does CT600 Tax Return Filing Mean for a Micro-Entity Company?

CT600 Tax Return Filing is not a special process reserved for micro-entities, and there is no separate official ‘micro-entity CT600’ form. The CT600 is HMRC’s standard Company Tax Return, used by companies of all sizes to report their Corporation Tax position. What differs for a micro-entity is usually the accounting framework it applies when preparing its statutory accounts, and the level of detail that appears in those accounts — not the existence of a different tax return. If a micro-entity company is within the charge to Corporation Tax, it may still need to submit a Company Tax Return to HMRC where one is required, and the figures from its accounting records and accounts will typically form the starting point for the Corporation Tax calculation. That calculation is not automatic: taxable profit can differ from accounting profit because adjustments may be required, for example where an item is treated differently for tax purposes than it is in the accounts, or where capital allowances are claimed instead of depreciation. It is also worth separating the filing from the payment, because submitting a CT600 and settling any Corporation Tax that is due are two distinct obligations. Not every micro-entity will have a Corporation Tax liability, and whether tax is payable depends on the company’s own taxable position, so the exact outcome varies from company to company.

What is a CT600?

CT600 is the form reference for the Company Tax Return that a UK company submits to HMRC. It reports the company's Corporation Tax position for an accounting period, covering the figures that determine whether tax is due. The CT600 is filed with HMRC and not with Companies House, and it is usually supported by a Corporation Tax computation and, where required, a copy of the statutory accounts. Most companies file their CT600 online, either directly or through an accountant or tax adviser.

Who needs to file a CT600?

Broadly, a company needs to file a Company Tax Return where it is within the charge to Corporation Tax and HMRC has issued it with a notice to file. The position can vary depending on the company's circumstances — for example, whether it has been dormant, newly incorporated, or has had a period of inactivity. A company can also have an obligation to tell HMRC about its liability even where no notice has been received. If you are unsure whether a return is required for your company, it is worth checking your specific position rather than assuming, because the answer depends on your company's activity and status.

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

Yes. They are two separate documents, with different purposes and different recipients. Statutory accounts are prepared under an accounting framework such as FRS 105 or FRS 102 and filed at Companies House, where they become publicly available. The CT600 is a tax return filed with HMRC that reports the company's Corporation Tax position. The accounts often provide the starting point for the tax figures, but the CT600 needs its own computation, and the two filings are made through different systems and on different timescales.

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

A micro-entity company is still a company for tax purposes, so it may need to file a Company Tax Return where one is required. There is no separate 'micro-entity CT600' form — the CT600 is the standard return used by companies generally. Whether a return is needed depends on the company's own circumstances, including whether HMRC has issued a notice to file and whether the company is within the charge to Corporation Tax. Simpler accounts do not automatically remove a filing obligation, and equally they do not automatically mean a return is required, so the company's individual position should be checked.

Is a CT600 different from a Corporation Tax computation?

Yes. The Corporation Tax computation is the working document that starts with your accounting profit and applies the adjustments needed to arrive at taxable profit and the resulting Corporation Tax liability. The CT600 is the return itself, which reports those figures to HMRC in the required format. You will normally need the computation before the CT600 can be completed accurately, which is why the two are usually prepared together as part of the same exercise.

How is taxable profit worked out from accounting profit?

Taxable profit starts with the company's accounting profit for the period and then adjusts for items that are treated differently for tax purposes. Typical adjustments include adding back expenditure that is not allowable for Corporation Tax, claiming capital allowances in place of depreciation, and dealing with income or expenditure that falls into a different period for tax than it does in the accounts. The result is the taxable profit on which Corporation Tax is calculated. Because the adjustments depend entirely on the company's own transactions and circumstances, there is no single formula — the computation has to be built from the company's records.

Is filing a CT600 the same as paying Corporation Tax?

No. Filing the CT600 is the reporting step: it tells HMRC what the company's Corporation Tax position is for the period. Paying Corporation Tax is a separate obligation, and any amount due is based on the liability shown in the computation and return. A company can file its return and still have tax to pay, and the filing date and the payment date are not the same. Keeping the two obligations distinct helps avoid confusion, particularly where a company has no liability but still has a return to submit.

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

Yes. A director or company officer remains responsible for the accuracy of the return, but an accountant or tax adviser can prepare the CT600, build the Corporation Tax computation, review the adjustments and submit the return to HMRC on the company's behalf. To do that, they will typically need your accounting records, details of income and expenditure, information on capital purchases, and any prior-period figures or correspondence from HMRC. Professional support is particularly useful where the accounts have been prepared elsewhere, where the company's activity has changed, or where you simply want the filing handled accurately and kept properly organised.
