CT600 Tax Return Filing in Buxton – Prepare and File Your Company Tax Return with HMRC

If your company needs to report its Corporation Tax position to HMRC, CT600 Tax Return Filing is the step that turns your accounting records into a submitted Company Tax Return. Our Buxton team supports limited companies through the whole process — reviewing the figures from your annual accounts, preparing the CT600, checking that the numbers agree with the underlying records, and submitting the return to HMRC. It is important to understand that a CT600 is not the same as the statutory accounts filed with Companies House. Statutory accounts are a separate filing obligation, and the CT600 reports your company’s Corporation Tax position to a different authority. Corporation Tax figures often need adjusting from the accounting profit shown in the accounts before the taxable profit is calculated, and that is where careful preparation really pays off. Whether you run a micro-entity, a small company or a growing business in and around Buxton, professional CT600 Tax Return Filing gives you accuracy, clarity and the convenience of having the return handled properly.

 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.

What Is a CT600 and How Does It Work for Micro-Entity Companies?

There is no separate official ‘micro-entity CT600’ form. A CT600 is the Company Tax Return that a UK company submits to HMRC to report its Corporation Tax position, and the same return is used regardless of the size of the company — what changes is the level of detail your figures and computations require. A micro-entity company preparing accounts under a small-company framework such as FRS 105 may still have Corporation Tax obligations, and where HMRC requires a Company Tax Return, one still needs to be submitted. The accounting framework used for your accounts does not by itself determine whether Corporation Tax is payable or how much is due; that depends on your company’s taxable profit and its particular circumstances. It also helps to keep two processes separate in your mind. Preparing the accounts is one job, and CT600 Tax Return Filing is another. They are closely related, because the figures in your accounts usually form the starting point for the Corporation Tax computation, but they are not the same thing. That computation may adjust your accounting profit — adding back disallowable expenses, allowing capital allowances instead of depreciation, and dealing with other tax-specific items — so taxable profit can differ from the profit shown in your accounts. Not every micro-entity will owe Corporation Tax, and the filing obligation and any Corporation Tax liability are separate matters that should be considered independently.

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 a UK company uses to file its Company Tax Return with HMRC. It reports the company's Corporation Tax position for an accounting period, setting out figures such as turnover, trading profits, and the Corporation Tax chargeable after any reliefs or adjustments that apply. The CT600 is submitted to HMRC, not to Companies House, and it sits alongside — but separate from — your statutory accounts.

Is a CT600 the same as statutory accounts?

No. Statutory accounts are prepared for the company's members and filed at Companies House, and they show the financial performance and position of the business. A CT600 is a tax return submitted to HMRC reporting the Corporation Tax position. The two documents are often based on the same underlying records, and the accounts figures usually feed into the Corporation Tax computation, but they serve different purposes, go to different authorities, and carry their own filing requirements.

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

It depends on the company's circumstances. A micro-entity that trades as a limited company may still have Corporation Tax obligations, and HMRC can require a Company Tax Return to be submitted where one is due. Being small, or preparing simpler accounts under a micro-entity framework, does not automatically remove the need to file where HMRC has issued a notice to deliver. Equally, filing a CT600 does not automatically mean Corporation Tax is payable — whether there is a liability depends on the company's taxable profit and the reliefs and adjustments that apply.

Is a CT600 different from a Corporation Tax computation?

Yes, although the two work together. The Corporation Tax computation is the working document that starts from your accounting profit and adjusts it to arrive at the taxable profit and the Corporation Tax due. The CT600 is the return that reports those results to HMRC. In practice, a well-prepared CT600 filing is supported by a clear computation, because HMRC may ask how the figures in the return were arrived at.

What information is needed to prepare a CT600?

Typically we need your company's accounting records and annual accounts for the period, details of income and expenses, information on any capital purchases or disposals, records of any reliefs or allowances claimed, and the company's registration details for HMRC. Bank statements, invoices, payroll information and details of any other income also help. If we already prepare your accounts, much of this will be on file already — and where something is missing, we will let you know exactly what is required.

How is taxable profit calculated from accounting profit?

The starting point is usually the profit shown in the accounts, but that figure is not automatically the taxable profit. The computation may add back expenses that are not allowable for tax, deduct capital allowances instead of depreciation, and account for income or expenditure that is treated differently for tax purposes. Adjustments can increase or reduce the profit figure, so the taxable profit and the accounting profit often differ. The exact adjustments depend on the company's activities and transactions.

Is filing a CT600 the same as paying Corporation Tax?

No — the filing obligation and the payment obligation are separate. Submitting a CT600 reports the Corporation Tax position to HMRC, while paying Corporation Tax is a separate step with its own timing and method. A company can have a filing requirement even where no Corporation Tax is payable, and the amount and timing of any payment depends on the company's circumstances and HMRC's published guidance.

What happens if a company files its CT600 late?

HMRC can apply penalties and interest where a Company Tax Return is filed after the deadline, and how those build up depends on how late the return is. Because the consequences vary with the company's circumstances, it is best to check HMRC's current guidance or speak to us as soon as you know a return is going to be late. Getting the return prepared and submitted as early as possible generally makes the situation easier to manage.
