 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.

CT600 Tax Return Filing for Micro-Entity Companies: What It Means in Practice

A micro-entity company can still have Corporation Tax obligations, and where HMRC requires a Company Tax Return, the company will need to submit a CT600. There is no separate official ‘micro-entity CT600’ form; the CT600 is the standard Company Tax Return used to report a company’s Corporation Tax position, regardless of its size. 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. Taxable profit can differ from accounting profit because the Corporation Tax computation may require adjustments, such as disallowable expenses or capital allowances. Whether a micro-entity actually owes Corporation Tax depends on its own circumstances and taxable position. It is also important to remember that filing the CT600 and paying any Corporation Tax due are separate obligations, each with its own requirements.

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

─── 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 your company's Corporation Tax position for an accounting period, including income, profits, gains, deductions, reliefs, and any Corporation Tax due or repayable. It is filed with HMRC, not Companies House, and may be required even if no Corporation Tax is payable.

Is a CT600 the same as statutory accounts?

No. Statutory accounts are prepared under company law and filed with Companies House. A CT600 is the Company Tax Return submitted to HMRC. The figures in your statutory accounts are often used as the starting point for the Corporation Tax computation, but they are not the same document as the CT600 and serve different legal and tax purposes.

Who needs to file a CT600?

A company generally needs to file a Company Tax Return if HMRC has issued a notice to deliver a return, or if the company has taxable profits, gains, or other circumstances that require a return. Not every company will owe Corporation Tax, but filing obligations depend on HMRC's notice and the company's specific situation. If you are unsure, it is best to check your position or seek professional advice.

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

A micro-entity company can still have Corporation Tax obligations and may need to file a CT600 if HMRC requires a Company Tax Return or if the company has taxable profits or other chargeable amounts. Being a micro-entity affects how you prepare and file your accounts, but it does not automatically remove the need to file a Company Tax Return with HMRC. Whether Corporation Tax is actually payable depends on the company's taxable position.

Is a CT600 different from a Corporation Tax computation?

Yes. A Corporation Tax computation is the calculation that starts with your accounting profit and makes the necessary tax adjustments to arrive at taxable profit and the Corporation Tax liability. The CT600 is the form used to report those figures to HMRC. You generally need a completed computation to fill in the CT600 correctly, but the two are separate parts of the process.

Can a company file its CT600 without filing its accounts?

CT600 filing and statutory accounts filing are separate obligations. A company may need to file its statutory accounts with Companies House and its Company Tax Return with HMRC. It is possible to prepare a CT600 using your accounting records even if the accounts have not yet been filed, but the accounts and tax return should be consistent and based on accurate information. The exact requirements depend on your company's circumstances.

What information is needed to prepare a CT600?

To prepare a CT600, you typically need your company's accounting records, statutory accounts or draft accounts, details of income and expenses, capital allowances, tax adjustments, losses, and any other relevant tax information for the accounting period. You also need the company's registration details and the accounting period dates. Complete and accurate records help ensure the return is prepared correctly.

Is filing a CT600 the same as paying Corporation Tax?

No. Filing the CT600 is the act of submitting your Company Tax Return to HMRC. Paying Corporation Tax is a separate obligation with its own timetable. A company may need to pay Corporation Tax before or after filing the return, depending on the amount due and HMRC's rules. The CT600 reports the liability, but the payment is handled separately.
