 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.

What Is a Micro-Entity CT600? Understanding CT600 Tax Return Filing for Small Companies

There is no separate official ‘micro-entity CT600’ form. Every UK company that has to deliver a Company Tax Return to HMRC uses the same CT600 — the form on which a company reports its Corporation Tax position. What differs for a micro-entity is not the tax return itself but the way the statutory accounts are prepared. A company that qualifies as a micro-entity may prepare its accounts under the micro-entity regime, which keeps the reporting requirements simple, but the accounting framework used does not by itself determine the company’s Corporation Tax liability. Accounts preparation and Corporation Tax filing are related but separate processes. Through CT600 Tax Return Filing in Barnstaple, we take the accounting profit shown in your records and review it for the adjustments HMRC expects — such as disallowable expenditure, capital allowances and other items that move accounting profit towards taxable profit. Whether any Corporation Tax is actually payable depends on the company’s own circumstances and taxable position. Filing the CT600 and paying any Corporation Tax that is due are also separate obligations, so a company may still need to submit a return even where no tax is payable.

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.

Let Us Take Care of Your CT600 Tax Return Filing in Barnstaple

A Company Tax Return rarely matches the accounts sitting in front of you. Working out which expenses are allowable, how accounting profit becomes taxable profit, and which records need to be kept and kept organised can quickly eat into the time you would rather spend running the business. Micro Entity Accounts takes that work off your desk, covering CT600 preparation, Corporation Tax computations, a review of the tax adjustments behind the figures, and submission of the return to HMRC. We keep the process clear and the explanations jargon-free, so you understand your Corporation Tax position before anything is filed. If your CT600 is due, or you simply want a careful second pair of eyes on the numbers, get in touch and we will talk you through the next steps.

What is a CT600?

The CT600 is the form HMRC provides for a company to report its Corporation Tax position for an accounting period. It brings together the company's figures, the tax adjustments made to them, and the resulting Corporation Tax liability, and it is submitted to HMRC alongside the supporting computations. When we talk about CT600 Tax Return Filing, we mean preparing that return properly and delivering it to HMRC by the deadline that applies to your company.

Who needs to file a Company Tax Return?

A company normally needs to file a Company Tax Return when HMRC has issued a notice to file, and there are other circumstances in which a return may be required, such as when a company has profits that are chargeable to Corporation Tax. Being dormant, being a micro-entity, or having no tax to pay does not automatically remove the obligation if HMRC has asked for a return. The position depends on each company's own circumstances, so it is worth checking before you assume nothing needs to be sent.

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

Yes, they are two separate filings with two different organisations. Statutory accounts are prepared under an accounting framework and filed with Companies House. The CT600 is a Company Tax Return submitted to HMRC and reports the company's Corporation Tax position for the period. They commonly start from the same accounting records, but they are prepared for different purposes and the figures on each are not necessarily identical — which is why accounts preparation and Corporation Tax filing are treated as related but distinct pieces of work.

Is a CT600 different from a Corporation Tax computation?

Yes. The computation is the working that starts with accounting profit and adjusts it to arrive at taxable profit and the Corporation Tax liability. The CT600 is the return form on which those results are reported to HMRC, supported by the computation. A well-prepared CT600 is usually built on a clear computation, which is why our CT600 Tax Return Filing service includes reviewing the adjustments — such as disallowable expenditure, depreciation and capital allowances — rather than simply copying the accounts across.

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

It may do. The micro-entity accounting regime affects how the statutory accounts are prepared; it does not create a special or separate tax return. A micro-entity company that has received a notice to file, or that has profits chargeable to Corporation Tax, will generally need to deliver a Company Tax Return to HMRC. Whether any Corporation Tax is actually payable depends on the company's taxable position and its own circumstances, and filing the CT600 is not the same thing as paying any tax that is due.

How is taxable profit calculated from accounting profit?

Taxable profit starts with the accounting profit shown in the company's records and is then adjusted for tax purposes. Typical adjustments include adding back expenditure that is not allowable for tax, removing depreciation charges, and claiming capital allowances where they are available, along with any other items HMRC expects to be treated differently. The result is the taxable profit on which Corporation Tax is calculated. The adjustments needed vary from company to company, so the computation should reflect your actual transactions rather than a standard template.

Is filing a CT600 the same as paying Corporation Tax?

No. Filing the return and paying any tax due are separate obligations with their own arrangements. A company can file its CT600 and find that no Corporation Tax is payable, and a company can owe Corporation Tax that must be paid regardless of when the return is submitted. We handle the preparation and submission of the return; we will also make sure you know what the computation shows so you can plan for any payment that follows.

What happens if a company files its CT600 late?

HMRC applies its own rules to returns that are filed after the deadline, and those rules can involve penalties and interest, with the outcome depending on the circumstances and how late the return is. We would rather help you avoid that situation than unpick it afterwards, so we work to a clear timetable once your records are with us. If you are already behind, the practical first step is to get the information together and bring the return up to date — we can guide you through that process.
