 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.

Understanding the CT600 for Micro-Entity Companies in Grantham

There is no separate official ‘micro-entity CT600’ form. A micro-entity company in Grantham may still have Corporation Tax obligations, and where HMRC requires it, the company must submit a Company Tax Return (CT600) to report its Corporation Tax position. The CT600 is distinct from the statutory accounts filed with Companies House, although the accounting records and accounts prepared for the company may be used as part of the Corporation Tax calculation. Taxable profit can differ from accounting profit because the Corporation Tax computation may require adjustments — for example, for disallowable expenses or capital allowances — before the taxable profit and any Corporation Tax liability are determined. Filing the CT600 and paying any Corporation Tax due are separate obligations: submitting the return does not itself make a payment, and a company may have a filing requirement even when no Corporation Tax is payable. Whether a micro-entity owes Corporation Tax depends on its own circumstances and taxable position.

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 Corporation Tax position for an accounting period, including income, gains, deductions, and reliefs. The CT600 is separate from the statutory accounts filed with Companies House. It is submitted to HMRC, typically online, and forms part of the Corporation Tax filing process.

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 has Corporation Tax obligations for an accounting period. This can include companies with taxable profits, companies that receive certain income, or companies that need to report a nil liability in some circumstances. Whether a particular company must file depends on its circumstances and HMRC's requirements. The CT600 is not limited to micro-entities.

Is a CT600 different from statutory accounts?

Yes. Statutory accounts are prepared for Companies House and for the company's members, and they follow the applicable accounting framework. A CT600 is a tax return submitted to HMRC. The accounting figures in the statutory accounts often form the starting point for the Corporation Tax computation, but tax adjustments may be needed to arrive at taxable profit. They are related but separate filings.

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 tax adjustments to arrive at taxable profit and the Corporation Tax liability. The computation is typically required to support the figures reported on the CT600. They work together, but they are not the same document.

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

A micro-entity company may need to file a CT600 if it has Corporation Tax obligations or if HMRC requires a Company Tax Return. Operating as a micro-entity, or preparing accounts under a micro-entity framework such as FRS 105, does not by itself determine whether Corporation Tax is payable or whether a CT600 is required. The company's own circumstances and taxable position determine the filing requirement. Filing the CT600 is separate from paying any Corporation Tax due.

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. Paying Corporation Tax is a separate obligation. A company may need to file a CT600 even if no Corporation Tax is payable, and filing the return does not itself make a payment. Any Corporation Tax due must be paid separately in line with HMRC's requirements.

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. A Corporation Tax computation is usually prepared to calculate taxable profit. You also need the company's Unique Taxpayer Reference (UTR) and details of the accounting period. Accurate record-keeping makes the process smoother.

What happens if a company files its CT600 late?

Filing late can lead to HMRC penalties and interest, and the exact consequences depend on the circumstances and HMRC's rules. It is best to file as soon as possible if you think you may miss a deadline, and to seek advice. Professional support can help you understand your position and take appropriate action.
