CT600 Tax Return Filing in Tyne & Wear — Preparing and Filing Your Company Tax Return with HMRC

CT600 Tax Return Filing in Tyne & Wear gives your company a clear, professionally supported route from year-end figures to a Company Tax Return submitted to HMRC. We help you pull together your accounting records, review the numbers and prepare the Corporation Tax computation, including the adjustments that turn your accounting profit into taxable profit. From there, the CT600 is prepared and filed with HMRC on your company’s behalf. It is worth being clear that a CT600 is not the same thing as your statutory accounts: statutory accounts are filed with Companies House, while the Company Tax Return is filed with HMRC. Many directors find that separating the two — and letting an experienced team handle the Corporation Tax side — makes the process more accurate, easier to follow and far less of a drain on their time. Our approach is straightforward: clear communication, transparent pricing and a proper explanation of the figures, not jargon.

 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 Is a CT600, and What Does It Mean for a Micro-Entity Company?

There is no separate official “micro-entity CT600” form. A CT600 is simply the Company Tax Return that a UK company submits to HMRC to report its Corporation Tax position — and it is the same core return used by companies of all sizes. Where micro-entities come in is in how the underlying figures are prepared. A company that qualifies as a micro-entity may prepare its statutory accounts under a simplified accounting framework, but that choice affects the accounts, not the existence of a Corporation Tax obligation. If your company is within the charge to Corporation Tax, or HMRC has issued a notice requiring a return, a Company Tax Return will generally need to be filed — although whether any Corporation Tax is actually payable depends on the company’s own circumstances and taxable position. It is also important to keep the CT600 separate from the statutory accounts filed with Companies House. The two are related but distinct obligations. Your accounting records and accounts usually feed into the Corporation Tax calculation, and the figures may need adjustments, which means taxable profit can differ from the accounting profit shown in the accounts. Finally, filing the CT600 and paying any Corporation Tax due are separate obligations — submitting the return does not itself settle the 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 formal name for the Company Tax Return that a UK company files with HMRC. It reports the company's Corporation Tax position for an accounting period, covering details such as the period covered, the company's turnover and trading activity, and the Corporation Tax calculation that supports the amount due. The CT600 is submitted electronically to HMRC and is a different document from the statutory accounts a company files with Companies House, even though the figures behind both often come from the same underlying accounting records.

Who needs to file a CT600?

A company generally needs to file a Company Tax Return if it is within the charge to Corporation Tax, or if HMRC has issued a notice requiring it to deliver a return. That will not apply in every situation, and whether a return is required can depend on the company's own circumstances, its activity during the period and any notice it has received. If you are unsure whether your company is expected to file, it is worth checking your position rather than assuming either way — and a professional can confirm what applies to you.

Is a CT600 different from statutory accounts?

Yes, and this is one of the most common points of confusion. Statutory accounts are prepared under an accounting framework and filed with Companies House. A CT600 is a tax return filed with HMRC. They serve different purposes, go to different bodies, and follow different rules. That said, they are closely connected: the figures in your accounts normally form the starting point for the Corporation Tax computation, which is then reflected in the CT600. Preparing accounts and preparing a Company Tax Return are related but separate processes.

Is a CT600 different from a Corporation Tax computation?

They are related but not the same thing. The Corporation Tax computation is the working document that starts with your accounting profit, applies the relevant tax adjustments, and arrives at your taxable profit and the Corporation Tax liability. The CT600 is the return in which those results are reported to HMRC. In practice you prepare the computation first, then use it to complete the return — which is why a well-built computation makes the CT600 far more straightforward to complete and review.

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

Possibly, depending on the company's circumstances. Being a micro-entity affects how you may prepare and file statutory accounts; it does not create a separate or different Company Tax Return. If the company is within the charge to Corporation Tax, or HMRC has required a return, a CT600 will generally need to be filed. Not every micro-entity will owe Corporation Tax — the company's own taxable position determines whether any tax is payable. Filing the return and paying any tax due are also separate obligations, so a nil or low liability does not automatically mean there is nothing to file.

What information is needed to prepare a CT600?

A typical CT600 preparation starts with your accounting records and the accounts for the period, including the profit and loss account and balance sheet. From there, we need details of income, expenses, fixed assets and any additions or disposals, plus information on matters that commonly require tax adjustments, such as depreciation, business entertaining, and other items treated differently for tax. Company details, the accounting period dates, and any relevant notices from HMRC are also needed. The exact list varies by company, and where records are incomplete we will tell you what is missing before we start rather than guessing.

How is taxable profit calculated from accounting profit?

Taxable profit normally begins with the accounting profit shown in your accounts, and then the Corporation Tax computation adjusts it. Some expenses deducted in the accounts are disallowed or restricted for tax purposes, and certain deductions or reliefs may reduce the taxable figure. Depreciation is a common example: it is charged in the accounts but normally replaced with the appropriate capital allowances treatment for tax. Because of these adjustments, taxable profit frequently differs from accounting profit, and the computation is the document that shows the bridge between the two.

Is filing a CT600 the same as paying Corporation Tax?

No. Filing the CT600 is the act of reporting your company's Corporation Tax position to HMRC, while paying Corporation Tax is a separate obligation that is settled through a separate payment. Submitting the return does not pay the tax, and the two can fall due at different points. It is therefore important to keep both in view: getting the return filed accurately, and making sure any liability is dealt with through the correct channel and in good time.
