 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.

Is There a Separate Micro-Entity CT600? Understanding CT600 Tax Return Filing for Micro-Entity Companies

There is no separate official ‘micro-entity CT600’ form. A micro-entity company uses the same CT600 Tax Return Filing process as other companies when it needs to submit a Company Tax Return to HMRC. Depending on the company’s circumstances, it may still have Corporation Tax obligations, and where HMRC requires a return, the company must prepare and file a CT600. The CT600 is separate from statutory accounts filed with Companies House, although the accounting records and accounts may be used as a starting point for the Corporation Tax calculation. Taxable profit can differ from accounting profit because Corporation Tax calculations may require adjustments, such as adding back disallowable expenses or claiming available reliefs. Not every micro-entity will owe Corporation Tax; the company’s taxable position and circumstances determine whether tax is payable. Filing the CT600 and paying any Corporation Tax due are also separate obligations, so it is important to manage both correctly.

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 form used to file a Company Tax Return with HMRC. It reports a company’s Corporation Tax position for an accounting period, including income, allowable deductions, and the resulting tax calculation. The CT600 is submitted to HMRC, not to Companies House, and it is separate from a company’s statutory accounts and Confirmation Statement.

What is a Company Tax Return?

A Company Tax Return is the broader return that companies submit to HMRC for Corporation Tax purposes. The CT600 is the main form within that return, and it is often accompanied by accounts and a Corporation Tax computation. The return allows HMRC to assess the company’s taxable profit and Corporation Tax liability for the period.

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. Not every company will owe Corporation Tax, but the filing requirement depends on the company’s circumstances and any notice received from HMRC. It is important to check the position for each accounting period.

Is a CT600 different from statutory accounts?

Yes. Statutory accounts are prepared for Companies House under the applicable accounting framework, while a CT600 is filed with HMRC for Corporation Tax. The two are related because the accounts often provide figures used in the tax computation, but they are separate filings with different purposes and different recipients.

Is a CT600 different from a Corporation Tax computation?

Yes. The CT600 is the HMRC form used to report the company’s tax position, while the Corporation Tax computation is the working paper that starts with accounting profit and applies tax adjustments to arrive at taxable profit. The computation supports the figures entered on the CT600 and helps explain how the liability has been calculated.

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 receives a notice from HMRC requiring a Company Tax Return. Being a micro-entity affects the accounting framework used for statutory accounts, but it does not automatically remove the need to file a CT600. The company’s specific circumstances determine whether a return is required and whether any Corporation Tax is payable.

Is filing a CT600 the same as paying Corporation Tax?

No. Filing a CT600 is the process of submitting the Company Tax Return to HMRC and reporting the company’s Corporation Tax position. Paying Corporation Tax is a separate obligation, and any payment due is made according to HMRCu2019s payment rules. A company can have a filing requirement even if no Corporation Tax is payable, and a tax liability can exist separately from the filing process.

Can someone prepare and file a CT600 on behalf of a company?

Yes. A company can authorise an accountant or tax agent to prepare and file its CT600 with HMRC. This can help ensure the return is completed accurately and that the supporting Corporation Tax computation is properly prepared. The company remains responsible for its tax affairs, but professional support can make the filing process more manageable.
