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

CT600 Tax Return Filing in Kirriemuir gives your company a clear, organised route to reporting its Corporation Tax position to HMRC. The CT600 is the Company Tax Return itself — a formal submission that sets out your company’s income, allowable deductions, tax adjustments and resulting Corporation Tax liability for the accounting period. It is a separate obligation from the statutory accounts you file with Companies House, even though the two are closely connected: the figures in your accounts normally form the starting point, and tax adjustments are then applied to arrive at taxable profit. Professional support means your accounting records are reviewed properly, the Corporation Tax computation is prepared with care, and the return is submitted accurately and on time. If you would rather not spend evenings wrestling with software, deadlines and disclosure boxes, we can handle the preparation and filing while keeping you informed of what has been submitted and why.

 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 Micro-Entity CT600? How CT600 Tax Return Filing Works for Smaller Companies

There is no separate official “micro-entity CT600” form. A CT600 is simply the Company Tax Return that companies use to report their Corporation Tax position to HMRC, and it applies to companies of all sizes, including those that qualify as micro-entities under the small companies regime. What differs for a micro-entity is usually the accounting framework and the level of detail in the statutory accounts, not the existence of a distinct tax return. If your company is within the charge to Corporation Tax, it may need to notify HMRC and, where required, submit a Company Tax Return for the relevant accounting period — but whether Corporation Tax is actually payable depends on your company’s own circumstances and taxable position, and a micro-entity will not automatically owe tax. It is also important to separate two things that are often confused. The statutory accounts prepared for Companies House are one filing obligation, while the CT600 is submitted to HMRC and reports the Corporation Tax calculation. Your accounting records and accounts normally feed into that calculation, but the taxable profit used for Corporation Tax can differ from the accounting profit shown in your accounts. This is because the Corporation Tax computation may include adjustments — for example, adding back disallowable expenditure or claiming available reliefs and allowances — before the final taxable profit and any Corporation Tax liability are determined. Filing the CT600 and paying any Corporation Tax due are also separate steps: submitting the return does not itself settle the tax.

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 Company Tax Return that a UK company submits to HMRC to report its Corporation Tax position for an accounting period. The return brings together the company's income, allowable deductions, any tax adjustments and the resulting Corporation Tax liability, along with supporting information and declarations. It is a tax filing rather than a set of accounts, and it is submitted to HMRC rather than to Companies House.

Who needs to file a CT600?

Whether a company needs to file a CT600 depends on its circumstances. Generally, a company that is within the charge to Corporation Tax and has been issued with a notice to deliver a Company Tax Return must complete and submit one for the relevant accounting period. Companies that are dormant, newly incorporated, or not trading can have different obligations, so it is worth checking your specific position rather than assuming a return is or is not required.

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. A CT600 is a tax return submitted to HMRC. The two are related, because the figures in your accounts normally provide the starting point for the Corporation Tax calculation, but they are separate documents, separate filing obligations and separate recipients. Submitting one does not discharge the other.

Is a CT600 different from a Corporation Tax computation?

They are different things, although they go together. The Corporation Tax computation is the working calculation that starts with your accounting profit and applies tax adjustments to arrive at taxable profit and the Corporation Tax liability. The CT600 is the return in which those results are reported to HMRC. A well-prepared computation underpins an accurate CT600, so the two are usually prepared side by side.

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

Being a micro-entity affects the accounting framework and the level of disclosure in your statutory accounts; it does not remove Corporation Tax obligations. There is no separate official micro-entity CT600 form — the same Company Tax Return applies. If your company receives a notice to deliver a return, or is within the charge to Corporation Tax in the relevant period, it may need to file one. Not every micro-entity will have Corporation Tax to pay, as that depends on the company's own taxable position.

How is taxable profit calculated from accounting profit?

Taxable profit normally begins with the accounting profit shown in your accounts, but it is rarely the same figure. The Corporation Tax computation adjusts for items that are treated differently for tax purposes — for example, expenditure that is not allowable as a deduction, income that is taxed in a different way, capital allowances, and any reliefs or losses available to the company. The result is the taxable profit on which any Corporation Tax liability is based, and those adjustments are reported through the CT600.

Is filing a CT600 the same as paying Corporation Tax?

No. Filing the CT600 and paying Corporation Tax are two separate obligations with their own processes. Submitting the return tells HMRC what your company's position is; it does not automatically settle any tax due, and the amount payable may differ from the final liability once the return is submitted. You should treat the filing and the payment as distinct tasks and keep records to support both.

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 CT600 to HMRC on its behalf. This usually involves an authorisation process so the agent can act for the company and file online. The company remains responsible for the accuracy of the information provided and for ensuring any Corporation Tax due is paid.
