 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.

Micro-Entities and CT600 Tax Return Filing: What You Need to Know

A micro-entity company does not have a separate official ‘micro-entity CT600’ form. The CT600 is the standard Company Tax Return used for Corporation Tax purposes, and a company that operates as a micro-entity may still need to file one with HMRC if it has a Corporation Tax filing obligation. For directors of smaller companies, CT600 Tax Return Filing still involves the same core steps: prepare the accounts and tax calculation, check the adjustments, and submit the Company Tax Return to HMRC. The CT600 is separate from the statutory accounts filed with Companies House, although the company’s accounting records and accounts often provide the starting point for the Corporation Tax calculation. Taxable profit can differ from accounting profit because the Corporation Tax computation may require adjustments, such as adjustments for disallowable expenses or tax-specific rules. Not every micro-entity will owe Corporation Tax, and whether a return is required, whether tax is payable, and how the calculation works depend on the company’s specific circumstances. Filing the CT600 and paying any Corporation Tax are also separate obligations: submitting the return does not itself make a payment, and paying tax does not replace the need to file.

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

What is a CT600?

A CT600 is the form used to submit a Company Tax Return to HMRC. It reports the company's income, profits, gains, deductions, and overall Corporation Tax position for an accounting period. The CT600 is a tax filing, not a set of statutory accounts, and it is normally supported by a Corporation Tax computation that explains how taxable profit has been calculated.

Is a CT600 different from statutory accounts?

Yes. Statutory accounts are prepared under an applicable accounting framework and filed with Companies House. A CT600 is a Company Tax Return submitted to HMRC for Corporation Tax purposes. The two are connected because the accounts often provide the starting figures for the tax calculation, but they are separate documents, separate filings, and they go to different authorities. Completing one does not automatically complete the other.

Is a CT600 different from a Corporation Tax computation?

Yes. The CT600 is the return form sent to HMRC, while the Corporation Tax computation is the supporting calculation that starts with the company's accounting profit and applies any necessary tax adjustments to arrive at taxable profit and the Corporation Tax liability. The computation is not the same as the CT600, but its figures normally feed into the return.

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 the company otherwise has a Corporation Tax filing obligation for an accounting period. This can include companies with taxable profits, companies with no tax to pay, and some dormant or non-trading companies depending on their circumstances. The right answer depends on the company's specific position, so it is worth checking rather than assuming no return is required.

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

A micro-entity company can still have Corporation Tax obligations. There is no separate official micro-entity CT600, so where a return is required the company uses the standard CT600 process. A micro-entity may prepare simpler accounts, but those accounts are separate from the CT600 and may still feed into the Corporation Tax calculation. Not every micro-entity will owe Corporation Tax, and filing the CT600 is separate from paying any tax due, so the company's circumstances determine what is required.

How is taxable profit calculated from accounting profit?

Taxable profit is not simply the profit shown in the accounts. The calculation starts with accounting profit and then applies tax adjustments, such as adding back disallowable expenses or treating certain income differently. The result is the taxable profit used to calculate any Corporation Tax liability, which is then reported on the CT600. Because adjustments can change the figure, the accounting profit and taxable profit are often different.

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 and reporting the Corporation Tax position. Paying Corporation Tax is a separate obligation, and any liability must be paid through the appropriate HMRC process. A company can have a CT600 filing requirement even if no Corporation Tax is payable, and filing the return does not automatically make a payment.

What happens if a company files its CT600 late?

If a CT600 is filed after the deadline, HMRC may treat it as late and may apply late filing penalties under its rules. The company should submit the return as soon as possible and check whether any Corporation Tax payment is also outstanding. The exact consequences depend on the circumstances, including the length of the delay and HMRC's position, so it is best to seek advice promptly rather than leave the filing unresolved.
