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

If your company needs to report its Corporation Tax position to HMRC, professional CT600 Tax Return Filing in Leicester takes the guesswork out of the process. We work through your accounting records, identify the tax adjustments that turn accounting profit into taxable profit, prepare a Corporation Tax computation to support the figures, and submit the Company Tax Return to HMRC on your behalf, keeping a clear record of what has been filed. It is worth remembering that the CT600 is a separate filing from the statutory accounts you send to Companies House — even when both are prepared from the same underlying figures, they serve different purposes and follow different rules. Our approach is straightforward: accurate preparation, transparent fixed-fee options, and practical support so directors understand exactly where their company stands.

 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.

Micro-Entities and the CT600: What Company Tax Return Filing Means for Smaller Companies

There is no separate official “micro-entity CT600” form. A CT600 is simply the Company Tax Return that a UK company uses to report its Corporation Tax position to HMRC, and it applies to companies of all sizes — including those that qualify as micro-entities for accounts purposes. A micro-entity company may still have Corporation Tax obligations, and where HMRC requires a Company Tax Return, the company needs to submit a CT600 reporting its income, allowable deductions and resulting tax position. The CT600 is separate from the statutory accounts filed with Companies House, although the two are linked: the figures in your accounting records and prepared accounts are normally the starting point for the Corporation Tax calculation. Because tax rules do not always follow accounting treatment, taxable profit can differ from accounting profit. Disallowable expenses, capital allowances, and other adjustments may need to be added back or deducted before the taxable profit and any Corporation Tax liability are determined, and that calculation sits behind the figures reported on the CT600. Not every micro-entity will owe Corporation Tax — whether anything is payable depends on the company’s own circumstances and taxable position. It is also important not to confuse filing with payment: submitting a CT600 to HMRC and paying any Corporation Tax due are separate obligations with separate processes.

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 formal name for the Company Tax Return that a UK company submits to HMRC. It sets out the company's income, deductions and reliefs for the accounting period, and reports the resulting Corporation Tax position. The CT600 is usually supported by a Corporation Tax computation and, in most cases, by a copy of the statutory accounts. It is a tax document filed with HMRC — not a Companies House document, and not a VAT Return or Confirmation Statement.

Who needs to file a CT600?

A company normally needs to file a Company Tax Return if HMRC has issued a notice to deliver one, or if the company has a Corporation Tax liability for the period. Whether a specific company must file in a given year depends on its circumstances, and HMRC can require a return even where no tax turns out to be payable. If you are unsure about your company's position, it is worth checking with an accountant rather than assuming no return is required.

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 for shareholders, Companies House and HMRC, and follow the applicable accounting framework. The CT600 is the Company Tax Return submitted to HMRC to report the company's Corporation Tax position. In practice the accounts are often attached to or referenced within the tax filing, and the accounting figures usually feed into the Corporation Tax calculation, but the obligations themselves remain distinct and have their own preparation requirements.

Is a CT600 different from a Corporation Tax computation?

They are related but not the same thing. The Corporation Tax computation is the working schedule that starts with accounting profit, makes the necessary tax adjustments, and arrives at taxable profit and the Corporation Tax figure. The CT600 is the return form on which those results are reported to HMRC. A well-prepared computation is what makes the figures on the CT600 defensible and easy to explain if HMRC asks questions later.

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

There is no separate micro-entity version of the CT600, and no automatic exemption simply because a company qualifies as a micro-entity for accounts purposes. A micro-entity company may still have Corporation Tax obligations and may be required to submit a Company Tax Return to HMRC. Whether a return is needed, and whether any Corporation Tax is actually payable, depends on the company's own circumstances and taxable position rather than its accounting size category alone.

Can a company file its CT600 without filing its accounts?

The two obligations run alongside each other, and the accounts figures normally underpin the tax figures reported on the CT600. In most cases the statutory accounts accompany the Company Tax Return, so preparing the return generally means having the accounts finalised first. There are limited situations where a company with no trading activity and no income sources to report can use certain simplified arrangements, but whether that applies is specific to the company, so it is worth taking advice before relying on it.

How is taxable profit calculated from accounting profit?

Accounting profit is your starting point, not the final answer. The Corporation Tax computation adjusts that figure — for example by adding back expenditure that is not allowable for tax, deducting items that are treated differently for tax, and applying available reliefs and allowances. The result is the taxable profit on which any Corporation Tax is calculated. Because these adjustments depend on the nature of your income and expenses, two companies with identical accounting profits can end up with quite different tax positions.

Is filing a CT600 the same as paying Corporation Tax?

No — filing and payment are separate. Filing is the act of submitting your Company Tax Return and computation to HMRC so your tax position is on record. Paying is the act of settling any Corporation Tax that is due. A company can file its return on time and still have a payment to make, or file a return showing no tax payable. Filing late or paying late can lead to HMRC penalties and interest under its published rules, so it is worth keeping both dates firmly in view.
