 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.

 Trustindex verifies that the original source of the review is Google. I highly recommend Imran to anyone looking for a reliable and knowledgeable accountant. 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.

I'm very pleased with the service I've received and truly appreciate his support. If you need help with your accounts or taxes, I would highly recommend Imran.

What Is a CT600 and How Does It Relate to Micro-Entity Companies?

A CT600 is the standard Company Tax Return that a UK company uses to report its Corporation Tax position to HMRC. There is no separate official ‘micro-entity CT600’ form; micro-entity status affects how statutory accounts may be prepared and filed with Companies House, but it does not create a different HMRC return. A micro-entity company may still have Corporation Tax obligations and, where HMRC requires a return or the company has a Corporation Tax liability, it will need to complete CT600 Tax Return Filing in the normal way. The CT600 is not the same as statutory accounts, a Confirmation Statement or a VAT Return. Your accounting records and statutory accounts often provide the starting point for the Corporation Tax computation, but the taxable profit used for Corporation Tax can differ from the accounting profit shown in the accounts. That is because the computation may require tax adjustments, such as disallowable expenses, capital allowances or other tax-specific treatments. The CT600 reports the resulting Corporation Tax position, while payment of any Corporation Tax due is a separate obligation from filing the return. Not every micro-entity will owe Corporation Tax, and whether a return is required depends on the company’s circumstances and HMRC’s requirements.

6 months late	HMRC estimates your tax bill and adds 10% of the unpaid tax

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 form used to report a company's Corporation Tax position to HMRC. It sets out the company's taxable profits or losses, the Corporation Tax charged or repayable, and other information HMRC requires for the accounting period. The CT600 is submitted to HMRC, not Companies House, and it is separate from the company's statutory accounts, Confirmation Statement and VAT Returns.

Is a CT600 different from statutory accounts?

Yes. Statutory accounts are prepared for the company's members and filed with Companies House under company law. A CT600 is a tax return filed with HMRC to report Corporation Tax. The accounts often inform the tax return because the accounting profit is a starting point for the Corporation Tax computation, but the CT600 requires tax adjustments and disclosures that do not appear in the statutory accounts. Preparing accounts and filing a CT600 are related but separate processes.

Who needs to file a CT600?

A company may need to file a CT600 if HMRC has issued a notice to deliver a Company Tax Return, or if it has Corporation Tax obligations for an accounting period. This can apply even if the company has no Corporation Tax to pay. Whether a return is required depends on the company's circumstances, so it is best to check HMRC's requirements or speak to an adviser if you are unsure.

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

Not automatically. A micro-entity company can still have Corporation Tax obligations and may need to file a CT600 if HMRC requires one or if it has taxable profits or other Corporation Tax matters. Micro-entity status mainly affects how accounts are prepared and filed with Companies House; it does not create a separate HMRC return or remove Corporation Tax filing requirements. The company's specific circumstances determine whether a CT600 is needed.

Is a CT600 the same as a Corporation Tax computation?

No. The Corporation Tax computation is the working paper that starts with accounting profit and applies tax adjustments to arrive at taxable profit and the Corporation Tax liability. The CT600 is the return that reports the results to HMRC. You normally need the computation to complete the CT600 accurately, but they are separate documents. A professional CT600 Tax Return Filing service often includes preparing or reviewing the computation as part of the process.

Is filing a CT600 the same as paying Corporation Tax?

No. Filing the CT600 is the act of submitting the Company Tax Return to HMRC. Paying Corporation Tax is a separate obligation. A company may file its return and then pay any Corporation Tax due by the relevant payment date, or it may have nothing to pay if its taxable position means no Corporation Tax is due. The filing and payment deadlines and processes are distinct, so it is important to keep both in mind.

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 simply the same figure. The Corporation Tax computation may add back disallowable expenses, deduct or adjust for capital allowances, account for non-taxable income, and apply other tax-specific rules. The result is the taxable profit used to calculate Corporation Tax. Because these adjustments depend on the company's circumstances, the CT600 should be prepared using the correct figures and supporting records.

What happens if a company files its CT600 late?

If a CT600 is filed after the deadline set by HMRC, HMRC may apply late filing penalties and other consequences under its rules. The exact treatment depends on the company's circumstances, how late the return is and HMRC's requirements. If a return may be late, it is usually best to act promptly, submit the CT600 as soon as possible and speak to HMRC or a professional adviser about the position. Every situation is different, so no specific outcome can be guaranteed.
