How to Submit Your Company Tax Return: Filing Form CT600 with HMRC


For just £54.99 plus VAT, our Corporation Tax registration service manages the entire process for you, ensuring that your application is accurately completed and submitted promptly. Company incorporation initiates a series of ongoing annual obligations, which are legal and financial requirements that a company must fulfill to remain in good standing. These obligations include filing an annual report, holding meetings, and maintaining proper records.

After incorporation, a new company has immediate tasks, such as opening a bank account and registering its address. Additionally, it must prepare for annual obligations, which include filing for its first financial year and conducting its inaugural annual general meeting. A financial year typically spans a 12-month period for which a company prepares its accounts. Every company is required to prepare accounts that report on:

  1. The performance and activities of the company during the financial year.
  2. The financial position of the company at the end of the year.

For an existing company, the new financial year begins the day after the previous financial year ends. In contrast, for a new company, the financial year starts on the day of incorporation. Financial years are defined in relation to an accounting reference period that concludes on a specific date, known as the accounting reference date (ARD). Companies can choose to prepare their accounts for the ARD or for a date that is up to 7 days before or after the ARD.

Key Takeaways

How to file a Company Tax Return with HMRC?

The Company Tax Return is used to determine and report the profit or loss for Corporation Tax, as well as to calculate the amount of Corporation Tax owed by the business, if any. This return must be submitted to HMRC online no later than 12 months after the end of the company’s accounting period for Corporation Tax.
You should still submit your Company Tax Return, even if you don't owe any tax this year. HMRC needs your tax return to understand your tax liability, and if you fail to submit it, you could incur a fine for not informing them.

To prepare a Company Tax Return, it is essential for your limited company to accurately complete and submit form CT600 to HM Revenue and Customs (HMRC) on an annual basis. This return must be accompanied by comprehensive annual accounts that detail the financial performance of the company over the fiscal year. The CT600 serves as the official Corporation Tax Return, which all active limited companies in the UK are obligated to file each year.

This document is crucial for declaring the company’s taxable profits, ensuring compliance with tax regulations, and determining the amount of Corporation Tax owed. It’s important to ensure that all figures are precise and that any relevant tax reliefs are properly claimed to minimize tax liabilities. Failure to file the CT600 or submit accurate accounts can result in penalties and interest charges, so it’s advisable to keep thorough records throughout the year and consider consulting with a tax professional if needed.

Key Takeaways

Does a company have to file an annual return every year?

Under normal circumstances, businesses are required to submit a single Company Tax Return each year. This filing reflects the annual accounting period for the company. However, if your annual accounts extend beyond a 12-month timeframe, you must file two separate tax returns.
The first return will cover the initial 12-month period of the accounting year, and the second return will address the remaining months. This approach ensures compliance with tax regulations and provides an accurate representation of your company’s financial activities over the extended period.


A Company Tax Return is a submission that Ltd Companies must provide to HMRC after the conclusion of their financial year. The primary component of the Company Tax Return is a form called CT600.

A Ltd Company’s financial year can end on the last day of any month, typically determined by the month in which the company was incorporated. The deadline for submitting your Company Tax Return is 12 months after the end of the accounting period it covers. If you miss this deadline, you will incur a penalty.

Additionally, there is a separate deadline for paying your Corporation Tax bill, which is usually 9 months and one day after the end of the accounting period. We recommend that all our clients file their returns well in advance of either deadline to ensure they know exactly how much they need to pay and when.

You can check your company’s year-end date on the Companies House website.

What is the purpose of a Company Tax Return?
The Company Tax Return (CT600) is a critical document that provides HMRC (Her Majesty’s Revenue and Customs) with detailed information about your company's taxable profit for the accounting period. This document plays a key role in determining the precise amount of corporation tax your company is obligated to pay.

Taxable profit can differ significantly from operating profit due to various factors, including the treatment of expenses, tax allowances, and the specific accounting practices employed. For instance, certain deductions and reliefs available under tax law can reduce your taxable profit, while operational expenses recorded on your income statement might not be fully deductible.

Given the complexities involved in preparing your tax return, it is essential to possess a thorough understanding of these financial nuances. If you are not fully confident in your ability to navigate this process, it is highly advisable to consult with a qualified expert, such as Coddan, who can ensure your accounts are accurately and optimally managed. This will help you avoid costly mistakes and maximize your potential tax efficiency.

Who has to file a Company Tax Return?
All limited companies, irrespective of their size or the revenue they generate, are obligated to file a Corporation Tax Return (CT600) with HM Revenue and Customs (HMRC). This requirement is crucial for compliance with UK tax regulations. Upon registration, HMRC will issue a Notice to Deliver a Company Tax Return detailing the specific deadline by which your return must be submitted.

It is essential to verify the accuracy of this deadline, as failing to file by the prescribed date can result in penalties and interest charges. If you believe that your filing date is incorrect or requires adjustment, it is your responsibility to contact HMRC promptly to address the issue.

Additionally, there are certain limited companies that may qualify for exemption from filing a Company Tax Return if they are classified by HMRC as dormant for Corporation Tax. A dormant company typically does not engage in any business activities or generate income during the accounting period. It is vital for companies to understand their status to ensure they meet all regulatory obligations.

How do I file a Company Tax Return?
Limited companies in the UK have the option to file their Corporation Tax Return (CT600) using the HMRC website or through specialized third-party software. It’s crucial to understand that along with the CT600, you must also submit your Company Accounts to HMRC simultaneously. These accounts are required in a specific electronic format known as iXBRL (Inline eXtensible Business Reporting Language), which ensures that the data is easily readable by software used by HMRC.

While certain accounting software programs can generate iXBRL-compliant accounts, we strongly advise business owners against attempting to prepare these documents themselves unless they possess significant experience and understanding of financial reporting standards. The complexity involved in creating accurate and compliant accounts can be daunting for those without a solid background in accounting.

Engaging the services of a qualified accountant or a professional financial advisor is highly recommended. A professional will not only prepare and file your Accounts and Corporation Tax Return accurately but will also keep you informed of any changes in tax legislation that may impact your business. By relying on expert assistance, you can minimize the risk of errors and avoid costly fines or penalties imposed by HMRC for late or incorrect filings. This investment in professional services can provide peace of mind, allowing you to focus on running your business effectively.


You are required to submit your company tax return within 12 months following the conclusion of the accounting period it encompasses. Typically, the accounting period corresponds to your company’s financial year; however, exceptions may occur during your first year of trading. It is not uncommon for the initial accounting period to extend beyond 12 months, particularly if your company was established partway through a financial year.

The end date of your company’s financial year is set by Companies House, which usually coincides with the last day of the month in which your company was incorporated. If necessary, you have the option to change your year-end date; just be aware that you can only make such a change once every five years. Therefore, it is crucial to carefully evaluate whether a change in your year-end date is justifiable and beneficial in the long term.

For your first accounting period, the accounts will span from the day your company was set up until the end of the following financial year. This initial period often exceeds 12 months, which may necessitate filing two CT600 returns with HMRC to ensure compliance with your tax obligations during that first year. This dual filing requirement applies only to your first year unless you opt to change your accounting year-end date subsequently. In the following years, your financial accounts will be structured to cover the period from the start to the end of the financial year, necessitating only one CT600 corporation tax return.

Additionally, it is essential to note that the deadline for paying your corporation tax bill is generally nine months and one day after the conclusion of the accounting period, in contrast to the 12-month timeline for filing the return. As a result, you must calculate your corporation tax obligation approximately three months before your tax return is due to ensure timely payment.

Fortunately, many of our clients proactively manage their accounting processes, often completing and submitting their accounts and CT600 returns well in advance of the established deadlines. This proactive approach significantly reduces the stress associated with timing issues and ensures compliance with HMRC regulations.

Late filing Penalties for the CT600 Company Tax Return
Fines for late filing can accumulate rapidly and significantly impact your business finances. If you miss the deadline for submitting your company tax return, HMRC will impose a series of penalties as follows:

  1. One Day Late:
    You will incur a penalty of £100. This fee is automatic and applies to any return submitted after the deadline.
  2. Three Months Late:
    An additional £100 penalty is charged, bringing the total to £200.
  3. Six Months Late:
    At this stage, HMRC will add a further penalty amounting to 10% of your estimated corporation tax bill. It’s important to note that this estimate is determined solely by HMRC, and you cannot challenge or appeal against this assessment.
  4. Twelve Months Late:
    Another penalty equivalent to 10% of your estimated corporation tax bill will be imposed, compounding the financial consequences of late submissions.

The repercussions of late filing escalate with each infraction. HMRC has a strict policy regarding timely submissions, and repeated delays are not taken lightly. If your tax return is filed late for three consecutive years, the penalties will significantly increase; the initial £100 fines will rise to £500 each.

Moreover, there are separate penalties associated with late payments of your corporation tax bill, which can further increase your liability.

While HMRC does recognize a limited number of reasonable excuses that may warrant an appeal for a penalty, the criteria are stringent. In our experience, consistently filing on time is the most effective strategy to avoid complications and scrutiny from HMRC, ensuring a smoother operational process for your business.

Company formation initiates the obligation to file annual reports and other compliance documents that are essential for maintaining good standing with the state and protecting the personal assets of the owners. After your company is formed, these annual filings, such as annual reports or franchise tax returns, provide updates to the state regarding your business’s current status and operational activities. Failing to meet these obligations can lead to penalties, fines, and potentially the dissolution of the business, making the connection between formation and ongoing filing critical for the company’s survival.

Every year, you are required to file a confirmation statement to verify details with Companies House and submit annual accounts to present a financial snapshot of the company. Missing these deadlines can result in financial penalties.

The formation of a new company marks the initial step of creating a legal business entity, while the filing of annual obligations represents the ongoing legal requirements that must be fulfilled to maintain that entity’s good standing with the state. The initial formation documents include basic information and establish the company’s legal presence. However, these are followed by recurring tasks, like filing annual reports and paying annual fees, which ensure the company remains active and compliant.

To manage annual filings, it is advisable to engage a company secretarial service or package that covers the submission of your Confirmation Statement, Annual Accounts to HMRC, and your Corporation Tax Return (CT600) to avoid late filing penalties.

You can utilize an online confirmation statement filing service that offers an express and fast-track electronic filing option to Companies House within 24 hours. If you wish to express file a confirmation statement for a UK company based in Scotland, Northern Ireland, or in England and Wales, our Web-Filing services are available to assist you today.

Alternatively, you may use a formation agent or online service to file your confirmation statement on your behalf for a fee that includes the official Companies House fee. Although you can download and complete the form CS01 and mail it to Companies House, this method is generally not considered express and may incur higher costs.

Be sure to verify the pre-populated information for accuracy, including the registered office, officers, and Persons with Significant Control (PSCs), as well as to confirm the company’s registered email address. Ensure that all details on the confirmation statement are correct and that your company’s activities are lawful, along with providing the required statement of lawful purpose.
