CT600 Tax Return Filing in Jarrow — Prepare and File Your Company Tax Return with HMRC

CT600 Tax Return Filing is the process of preparing your company’s Corporation Tax position and submitting a Company Tax Return to HM Revenue & Customs. It is a separate obligation from the statutory accounts you file with Companies House, even though both start from the same underlying accounting records. Professional support can help you pull the figures together accurately, work through the Corporation Tax computation, and file the CT600 on time, so you are not trying to decipher HMRC’s requirements in the middle of running a business in Jarrow. Our approach is straightforward: we review the accounts, consider the tax adjustments that may be needed to arrive at taxable profit, prepare the return, and submit it to HMRC on your behalf. You keep a clear record of what has been filed and why, with fixed-fee options and clear, transparent pricing rather than a bill that grows as the questions do.

 Trustindex verifies that the original source of the review is Google. We worked with a few different accountants before finally settling with Accotax, and we’re really glad we did. Their team is great. Abdul is responsive and easy to reach whenever I have a question, which makes a big difference. They take the time to understand how our business works and what our needs are. They are very knowledgeable, and when they don’t have the answer straight away, they take the time to look into it and get back to us quickly. Anum, who looks after our account on a day-to-day basis, including reconciling invoices and preparing the annual accounts, is amazing. She is professional, efficient, and follows the processes we have put in place together. She's also very quickin getting back to us whenever needed. We’re very happy to work with her and hope to continue doing so for as long as possible. Overall, Accotax has made our accounting experience much smoother and easier. We see them as a long-term partner as our business continues to grow. I would 100% recommend them.

 Trustindex verifies that the original source of the review is Google. I have really impressed to date with all dealings with Accotax highly enough. From day one, they've made what can often be a complicated and stressful part of running a business feel straightforward and hassle-free. A special mention has to go to Anum, who has been friendly, incredibly responsive, and genuinely cares about providing the best possible service. No question is ever too much trouble, and she consistently goes above and beyond to make sure everything is dealt with efficiently. I wouldn't hesitate to recommend you to anyone looking for an accountant they can genuinely trust.

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

There is no separate official form called a micro-entity CT600. A CT600 is simply a Company Tax Return — the return that a company submits to HMRC to report its Corporation Tax position. The term is sometimes used informally to describe CT600 Tax Return Filing for companies that prepare their accounts under the micro-entity regime, because those companies often have particular accounting considerations even though they file the same type of Corporation Tax Return as any other company. If your company is a micro-entity, it may still have Corporation Tax obligations, and where HMRC requires a Company Tax Return to be filed, the CT600 is the route for reporting that position. Whether Corporation Tax is actually payable depends on the company’s own circumstances and taxable position — not every micro-entity will owe tax. The CT600 is also separate from the statutory accounts filed at Companies House and from the Corporation Tax payment itself. Your accounting records and the accounts you prepare are usually the starting point for the Corporation Tax calculation, but taxable profit can differ from accounting profit, because the tax computation may need adjustments for items such as disallowable expenditure or capital allowances. Preparing the accounts and filing the CT600 are related but distinct processes, and it is the adjusted taxable profit that drives the Corporation Tax liability.

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 name of the form used to submit a Company Tax Return to HMRC. It sets out the company's Corporation Tax position for an accounting period, including details such as the company's turnover, profit figures and the tax due, along with the tax computation and other supporting information that HMRC requires. It is a Corporation Tax document, not a Companies House document.

Who needs to file a CT600?

A company registered at Companies House is generally expected to notify HMRC when it starts to carry on business activity, and HMRC will then issue a notice to deliver a Company Tax Return where one is required. Whether a specific company must file a CT600 depends on its own circumstances and on whether HMRC has issued a notice to file. If you are unsure about your company's position, it is worth checking with HMRC or with an accountant rather than assuming you are exempt.

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

Yes — they are two separate filings with two different bodies. Statutory accounts are prepared under an accounting framework and filed at Companies House, while the CT600 is the Corporation Tax return submitted to HMRC. Even though both are built from the same accounting records, the figures on the CT600 may not match the accounts exactly, because the Corporation Tax computation can adjust the accounting profit to arrive at taxable profit.

Is a CT600 the same as a Corporation Tax computation?

No. The Corporation Tax computation is the working paper that starts with the company's accounting profit and makes the adjustments needed to reach taxable profit and the resulting Corporation Tax liability. The CT600 is the return form itself, which reports those figures to HMRC. In practice, the computation usually accompanies the return, but they are distinct pieces of work and it is the computation that explains how the liability was arrived at.

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

Not automatically, and not simply because it qualifies as a micro-entity. Being a micro-entity affects how the accounts are prepared and what is filed at Companies House — it does not create or remove a Corporation Tax filing obligation. If HMRC has issued a notice to deliver a Company Tax Return, the company is expected to comply, and where the company has taxable profits, Corporation Tax may be payable. This is why accounts preparation and Corporation Tax filing are best treated as two related but separate jobs.

Can a company file its CT600 without filing its accounts?

The CT600 is filed with HMRC and the statutory accounts are filed with Companies House, so they are separate submissions under separate rules. In most cases, the figures on the CT600 are drawn from the prepared accounts, so the accounts normally need to be finalised first. A company's filing obligations at Companies House do not disappear because the tax return has been submitted, and vice versa — both need to be dealt with.

How is taxable profit calculated from accounting profit?

Taxable profit usually begins with the accounting profit shown in the prepared accounts and is then adjusted. Typical adjustments include adding back expenditure that is not allowable for tax purposes, deducting capital allowances instead of depreciation, and accounting for any income or expenses that are treated differently for tax. The result is the taxable profit on which the Corporation Tax liability is calculated. Because those adjustments depend on the company's transactions, the taxable figure can be higher or lower than the accounting profit.

Is filing a CT600 the same as paying Corporation Tax?

No — filing and paying are separate obligations. Submitting the CT600 reports the company's Corporation Tax position to HMRC, while the payment of any Corporation Tax due is handled separately through HMRC's payment arrangements. A company can have a filing obligation even where no Corporation Tax is payable, and a company that owes tax still needs to submit its return. Your accountant can help you keep track of both.
