 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.

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 Does CT600 Tax Return Filing Mean for Micro-Entity Companies?

For a company that qualifies as a micro-entity, CT600 Tax Return Filing is not a different or special HMRC form; it is the same Company Tax Return process that applies to companies within Corporation Tax. A micro-entity may still have Corporation Tax obligations and, where HMRC requires it or its circumstances mean a return is due, it will need to submit a CT600 to HMRC. The CT600 is separate from the statutory accounts filed with Companies House, and from other filings such as a Confirmation Statement or VAT Return. The company’s accounting records and prepared accounts often provide the starting point for the Corporation Tax computation, but the taxable profit can differ from the accounting profit because tax adjustments may be needed, for example for disallowable expenses, capital allowances, or other tax rules. Preparing accounts under a micro-entity framework such as FRS 105 does not by itself determine the Corporation Tax liability. The company’s circumstances and taxable position determine whether Corporation Tax is payable, and filing a CT600 is separate from paying any Corporation Tax that is due.

3 months late	A further £100
6 months late	HMRC estimates your tax bill and adds 10% of the unpaid tax
12 months late	A further 10% of any unpaid tax

Penalty levels are set by Companies House and may change. Separate HMRC penalties and interest apply to a late Corporation Tax return and unpaid tax. Check the updated guide here.

What is CT600 Tax Return Filing?

CT600 Tax Return Filing is the process of preparing and submitting a Company Tax Return to HMRC. The CT600 is the form used to report a company's Corporation Tax position for an accounting period. It brings together figures from the company's accounts and the Corporation Tax computation, including any tax adjustments needed to arrive at taxable profit. Filing the CT600 tells HMRC how the company's Corporation Tax position has been calculated; it is separate from filing statutory accounts with Companies House. To prepare it, an accountant usually needs the company's accounting records, draft or final accounts, and supporting tax information.

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. Not every company will have a Corporation Tax liability, but a filing requirement can still arise, and dormant or newly incorporated companies may have specific positions depending on their circumstances. If you are unsure whether your company needs to file, it is best to check the position based on HMRC notices and the company's activity.

Is a CT600 different from statutory accounts filed with Companies House?

Yes. A CT600 is a Company Tax Return submitted to HMRC and deals with Corporation Tax. Statutory accounts are prepared under the applicable accounting framework and filed with Companies House as a separate obligation. The accounts provide important figures for the tax return, but they do not replace the CT600, and filing the CT600 does not satisfy the Companies House accounts filing requirement. Other filings, such as a Confirmation Statement or VAT Return, are also separate.

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 the necessary tax adjustments to arrive at taxable profit and the Corporation Tax liability. The two are closely linked and are usually prepared together, but they serve different purposes: the computation explains the numbers, and the CT600 reports them to HMRC.

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

A micro-entity company may still need to file a CT600 if HMRC requires a Company Tax Return or if it has Corporation Tax obligations. There is no separate official micro-entity CT600; the same CT600 framework applies. The fact that a company prepares micro-entity accounts affects how the accounts are prepared, not whether a CT600 is due. The company's circumstances and taxable position determine whether Corporation Tax is payable, and filing the CT600 is separate from paying any Corporation Tax due.

How is taxable profit calculated from accounting profit?

Taxable profit is not always the same as the accounting profit shown in the accounts. The Corporation Tax computation usually starts with the accounting profit and then makes adjustments required by tax rules. These may include adding back disallowable expenses, deducting allowable expenses or reliefs, adjusting for capital allowances instead of depreciation, and taking account of losses or other reliefs where available. The result is the taxable profit used to calculate the Corporation Tax liability, subject to the company's circumstances and the tax rules in force.

Is filing a CT600 the same as paying Corporation Tax?

No. Filing a CT600 is the reporting process: it tells HMRC the company's Corporation Tax position for the period. Paying Corporation Tax is a separate obligation, and any liability normally needs to be paid according to HMRC's payment rules for the company's circumstances. A company can have a filing requirement even if no Corporation Tax is payable, and submitting the return does not itself make a payment.

What happens if a company files its CT600 late?

Filing a CT600 late can lead to consequences under HMRC's rules, which may include reminders, penalties, or other action. The exact outcome depends on the circumstances, including the reason for the delay and any reasonable excuse, so it is important to act quickly and seek advice if a return is overdue. Bringing the filing up to date and keeping HMRC informed is usually the practical first step.
