 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.

Understanding CT600 Tax Return Filing for Micro-Entity Companies

A micro-entity company may still have Corporation Tax obligations, and where HMRC requires it, the company needs to submit a Company Tax Return (CT600). There is no separate official ‘micro-entity CT600’ form — the CT600 is the same Company Tax Return used by companies to report their Corporation Tax position, though micro-entities may have particular accounting and reporting considerations. The CT600 is separate from the statutory accounts filed with Companies House, although the company’s accounting records and accounts often form the starting point for the Corporation Tax calculation. It is important to note that taxable profit can differ from accounting profit because the Corporation Tax computation may require adjustments, such as adding back disallowable expenses or claiming available reliefs. Not every micro-entity will owe Corporation Tax; whether tax is payable depends on the company’s circumstances and taxable position. Also, filing the CT600 and paying any Corporation Tax due are separate obligations.

3 months late	A further £100
6 months late	HMRC estimates your tax bill and adds 10% of the unpaid tax
12 months late	A further 10% of any unpaid tax

Penalty levels are set by Companies House and may change. Separate HMRC penalties and interest apply to a late Corporation Tax return and unpaid tax. Check the updated guide here.

─── FAQs

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 the company's Corporation Tax position, including taxable profits and any Corporation Tax due. It is not a separate form for micro-entities; it is the standard Company Tax Return that applies to companies within the scope of Corporation Tax. The CT600 is separate from statutory accounts, which are filed with Companies House.

Who needs to file a CT600?

A company usually needs to file a CT600 if HMRC has issued a notice to deliver a Company Tax Return, or if the company has taxable profits or other circumstances that require a return. Not every company will need to file one, so it is important to check HMRC's requirements based on your company's specific situation. If you are unsure, professional advice can help clarify your obligations.

Is a CT600 different from statutory accounts?

Yes. A CT600 is a Corporation Tax Return submitted to HMRC, while statutory accounts are the financial statements filed with Companies House. They serve different purposes and go to different authorities. The figures in your statutory accounts may be used to prepare the CT600, but tax adjustments are often needed to arrive at the taxable profit reported to HMRC.

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

A micro-entity company may need to file a CT600 if HMRC requires it or if the company has a Corporation Tax liability or other reporting obligation. Being a micro-entity affects the accounting framework used for statutory accounts, but it does not automatically remove the need to file a Company Tax Return. Whether a CT600 is required depends on the company's circumstances, so it is best to confirm with HMRC guidance or a professional adviser.

What information is needed to prepare a CT600?

To prepare a CT600, you typically need the company's accounting records, statutory accounts or draft accounts, details of income and expenses, capital allowances information, and any other tax adjustments. You may also need information about payments already made, reliefs claimed, and any relevant correspondence from HMRC. Accurate records make the preparation process smoother and help ensure the return reflects the company's 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. Corporation Tax calculations may require adjustments, such as adding back expenses that are not allowable for tax, deducting capital allowances, or accounting for other reliefs and exemptions. The result is the taxable profit used to calculate Corporation Tax. Because these adjustments can be technical, professional support with the CT600 Tax Return Filing process can help.

Is filing a CT600 the same as paying Corporation Tax?

No. Filing a CT600 is the act of submitting the Company Tax Return to HMRC, which reports the company's Corporation Tax position. Paying Corporation Tax is a separate obligation, and any tax due must be paid according to HMRC's payment deadlines. Filing the return and making payment are distinct steps, so it is important to keep both in mind.

What happens if a company files its CT600 late?

If a CT600 is filed late, HMRC may take action, and the company could face penalties or interest. The exact consequences depend on the circumstances and HMRC's rules. It is always best to file on time or contact HMRC as soon as possible if you are having difficulty. Professional support can help you manage the filing process and avoid unnecessary delays.
