 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.

 Trustindex verifies that the original source of the review is Google. I have really impressed to date with all dealings with Accotax highly enough. 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 CT600? Micro-Entity Companies and CT600 Tax Return Filing in Kirkwall

A CT600 is the Company Tax Return that a UK company submits to HMRC to report its Corporation Tax position. For CT600 Tax Return Filing in Kirkwall, the key point is that there is no separate official ‘micro-entity CT600’ form; micro-entity companies use the same CT600 framework where HMRC requires a Company Tax Return. A micro-entity company may still have Corporation Tax obligations and, depending on its circumstances and taxable position, may need to prepare and file a CT600. Micro-entity status can affect how statutory accounts are prepared, but it does not automatically determine whether Corporation Tax is payable. The CT600 is separate from the statutory accounts filed with Companies House. Your accounting records and accounts often provide the starting point for the Corporation Tax calculation, but taxable profit can differ from accounting profit because the computation may require tax adjustments, such as adding back disallowable expenditure or allowing reliefs and capital allowances where relevant. For companies in Kirkwall, it is important to treat accounts preparation and Corporation Tax filing as related but separate processes. Filing the CT600 and paying any Corporation Tax due are also separate obligations: the return reports the position, while payment depends on whether tax is payable.

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 the company's tax figures, including the calculation of taxable profit and the resulting Corporation Tax liability, alongside other required disclosures. The CT600 is submitted to HMRC, not Companies House. It is a tax filing, so it is separate from the statutory accounts that a company may need to prepare and file under company law. Depending on the company's circumstances, the CT600 may be supported by a Corporation Tax computation and other records.

Who needs to file a CT600?

A company may need to file a CT600 if HMRC requires it to submit a Company Tax Return. This can apply to companies with Corporation Tax obligations, and in some cases a return may still be required even if no Corporation Tax is payable. Whether a particular company must file depends on its circumstances, including whether it is within the scope of Corporation Tax and whether HMRC has issued a notice to deliver a return. If you are unsure about your company's position, professional advice can help clarify the requirement.

Is a CT600 different from statutory accounts?

Yes. A CT600 is a Company Tax Return submitted to HMRC, while statutory accounts are the financial statements prepared under company law and generally filed with Companies House. The two are related because the accounts often provide figures used in the Corporation Tax calculation, but they serve different purposes and are filed with different bodies. Statutory accounts do not replace a CT600, and a CT600 does not replace statutory accounts. A company may have separate filing obligations for both.

Is a CT600 different from a Corporation Tax computation?

Yes. The CT600 is the return form submitted to HMRC, while the Corporation Tax computation is the supporting calculation that starts with accounting profit and makes the tax adjustments needed to arrive at taxable profit. The computation shows how the figures in the CT600 were derived, including items such as disallowable expenditure, capital allowances and other tax adjustments where relevant. The computation is often prepared alongside the CT600 to support the figures and explain the tax position properly.

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

A micro-entity company may need to file a CT600 if HMRC requires it to submit a Company Tax Return. There is no separate official micro-entity CT600 form. Micro-entity status affects how the statutory accounts may be prepared, but it does not automatically determine whether Corporation Tax is payable or whether a return must be filed. If the company has taxable income or HMRC has issued a notice to deliver a return, a CT600 may be required. Filing the return and paying any Corporation Tax due are separate obligations, and not every micro-entity will owe Corporation Tax.

What information is needed to prepare a CT600?

To prepare a CT600, you usually need the company's accounting records for the relevant period, including income, expenses, assets and liabilities. Statutory accounts, a trial balance or management accounts can provide the starting figures, along with details of any tax adjustments such as disallowable expenses, capital expenditure, capital allowances, losses or reliefs. You may also need company registration details, the company's Unique Taxpayer Reference and information from previous returns or computations. The exact information depends on the company's circumstances and the complexity of its tax position.

How is taxable profit calculated from accounting profit?

Taxable profit starts with the accounting profit shown in the company's accounts, but it is not always the same figure used for Corporation Tax. The Corporation Tax computation may require adjustments, such as adding back expenditure that is not allowable for tax, deducting allowable items that are not in the accounts, replacing accounting depreciation with capital allowances where relevant, and accounting for losses or reliefs. The result is the taxable profit on which Corporation Tax is calculated according to the rules that apply to the company. Because adjustments can increase or decrease the profit figure, taxable profit can differ from accounting profit.

Is filing a CT600 the same as paying Corporation Tax?

No. Filing a CT600 is the process of submitting the Company Tax Return to HMRC to report the company's Corporation Tax position. Paying Corporation Tax is a separate obligation and only applies if the company has a liability to pay after the taxable profit and available reliefs are calculated. A company may need to file a CT600 even when no Corporation Tax is payable, and filing the return does not automatically settle any tax due. Payment deadlines and methods depend on HMRC's rules and the company's circumstances.
