 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.

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

If you run a micro-entity company in Glasgow, it is easy to assume that smaller accounting requirements mean there is a separate official micro-entity CT600 form. There is not. A micro-entity is an accounting classification, while the CT600 is the Company Tax Return used to report a company’s Corporation Tax position to HMRC. Depending on the company’s circumstances and taxable position, a micro-entity company may still have Corporation Tax obligations and may need to submit a Company Tax Return as part of its CT600 Tax Return Filing. The CT600 is separate from statutory accounts filed with Companies House, although the 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 disallowable expenses or capital allowances where relevant. Filing the CT600 and paying any Corporation Tax due are also separate obligations: the return reports the position, while payment depends on whether tax is actually payable.

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.

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 for a Company Tax Return submitted to HMRC. It reports a company's Corporation Tax position for an accounting period, bringing together details such as income, allowable deductions, reliefs and the resulting Corporation Tax calculation. The CT600 is not filed with Companies House and is not the same as statutory accounts, a Confirmation Statement or a VAT Return. CT600 Tax Return Filing is the process of preparing this return, checking the figures and submitting it to HMRC.

Who needs to file a CT600?

A company that is within the scope of Corporation Tax will generally need to file a Company Tax Return if HMRC has issued a notice to deliver, or if it has taxable profits or other amounts that must be reported. Smaller companies and micro-entities are not automatically outside the CT600 system simply because they have simpler accounting requirements. Whether a particular company needs to file depends on its circumstances, its taxable position and HMRC's rules. If you are unsure, professional advice can help clarify the position before any CT600 Tax Return Filing is due.

Is a CT600 different from statutory accounts?

Yes. Statutory accounts are prepared for the company's members and filed with Companies House under the applicable accounting framework. A CT600 is a Company Tax Return submitted to HMRC and focuses on the Corporation Tax position for the accounting period. The accounts may provide the starting figures for the tax computation, but they are a separate document with a separate filing route. Completing CT600 Tax Return Filing does not, by itself, satisfy the company's Companies House obligations, and filing accounts with Companies House does not replace the CT600.

Is a CT600 different from a Corporation Tax computation?

Yes. The CT600 is the return form and supporting schedules that are submitted to HMRC, while the Corporation Tax computation is the working paper that shows how accounting profit has been adjusted to reach taxable profit and the resulting Corporation Tax liability. The computation supports the figures entered on the CT600. In practice, CT600 Tax Return Filing often involves preparing both the computation and the return so that the tax position is properly documented.

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

It may need to. A micro-entity is an accounting classification, not a separate tax regime, so there is no official micro-entity CT600 form. A micro-entity company can still have Corporation Tax obligations and may need to submit a Company Tax Return depending on its circumstances and taxable position. The accounting framework used for the accounts, such as FRS 105, does not by itself determine whether Corporation Tax is payable. Filing a CT600 and paying Corporation Tax are also separate: the return reports the position, while payment depends on whether tax is due.

How is taxable profit calculated from accounting profit?

Taxable profit usually starts with the accounting profit shown in the company's accounts, but it is not simply the same figure. The Corporation Tax computation may require adjustments, such as adding back expenses that are not allowable for tax, deducting allowable expenses, claiming capital allowances where relevant, and dealing with losses or reliefs. The result is the taxable profit used to calculate the Corporation Tax liability. Because these adjustments depend on the company's transactions and circumstances, careful review is an important part of CT600 Tax Return Filing.

Is filing a CT600 the same as paying Corporation Tax?

No. Filing a CT600 is the reporting step: it tells HMRC about the company's Corporation Tax position for the period. Paying Corporation Tax is a separate obligation, and payment is only relevant if the return shows tax is due. A company could file its CT600 and have no tax to pay, or it could have tax to pay and need to arrange payment through HMRC separately. CT600 Tax Return Filing and Corporation Tax payment should therefore be treated as distinct tasks when managing deadlines and records.

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

Yes. A company can authorise an accountant, tax adviser or agent to prepare and submit its Company Tax Return to HMRC on its behalf. The company and its directors remain responsible for the information provided and for ensuring filing obligations are met, but professional support can help with CT600 preparation, Corporation Tax computations, tax adjustment review and HMRC filing. This can be particularly useful for directors in Glasgow who want their CT600 Tax Return Filing handled alongside their wider accounting records.
