A company may be considered dormant when it has stopped trading and has no other income. However, being dormant does not mean that all company filing responsibilities automatically disappear.
For UK company directors, one of the most common questions is: Does a dormant company need to file a tax return?
The answer depends on whether the company is dormant for Corporation Tax purposes and whether HMRC has asked the company to submit a Company Tax Return. Companies House also has separate requirements for dormant companies.
This guide explains the key dormant company tax return UK rules for 2026, including Corporation Tax, annual accounts, confirmation statements and accounting responsibilities.
What Is a Dormant Company?
A company can be dormant when it is not carrying on business and has no other income, such as investment income.
However, the definition of dormant can differ between HMRC and Companies House. A company may be dormant for Corporation Tax purposes but still have filing obligations with Companies House.
This distinction is important because directors should not assume that declaring a company dormant removes every legal responsibility.
Does a Dormant Company Need to File a Tax Return?
Generally, if HMRC has officially treated your company as dormant for Corporation Tax, you do not normally need to pay Corporation Tax or file Company Tax Returns for the dormant period.
If your company has stopped trading and has no other income, you can tell HMRC that the company is dormant for Corporation Tax purposes. HMRC may also contact you and confirm that it considers the company dormant.
However, if HMRC has issued a notice requiring the company to file a Company Tax Return, the company may still need to submit one. Therefore, simply stopping trading is not enough to assume that no tax return is required.
Dormant for Corporation Tax vs Dormant for Companies House
One of the biggest areas of confusion is that there are two different concepts of dormancy.
Dormant for Corporation Tax
A company can be dormant for Corporation Tax when it is no longer trading and has no other income.
HMRC can treat the company as dormant, meaning it generally does not have to pay Corporation Tax or file Company Tax Returns while it remains dormant.
Dormant for Companies House
Companies House considers a company dormant when it has had no significant transactions during the financial year.
Certain transactions, such as Companies House filing fees, late filing penalties and payments for shares when the company was incorporated, do not normally prevent the company from being considered dormant.
Because the definitions are different, a company can be dormant for Companies House purposes but still have Corporation Tax obligations with HMRC.
Does a Dormant Company Still Need to File Annual Accounts?
Yes.
A dormant limited company generally still needs to file annual accounts with Companies House. Companies House confirms that all limited companies must deliver accounts, whether they trade or not, although specific exemptions can apply to certain dormant subsidiaries.
Dormant company accounts are usually simpler than accounts for a trading company.
For example, dormant accounts filed with Companies House generally do not need to include a profit and loss account or directors' report. Instead, they normally include a balance sheet, relevant notes and the required dormant-company statements.
What Is the Filing Deadline for Dormant Accounts?
Dormant companies have the same filing deadlines as other companies for Companies House accounts.
For a private limited company, annual accounts are generally due 9 months after the end of the company's financial year. The same late filing penalties can apply to dormant accounts.
For example, if a dormant company's financial year ends on 31 December 2025, its annual accounts would generally be due by 30 September 2026.
Directors should therefore track the Companies House deadline even when the company has no trading activity.
Does a Dormant Company Need to File a Confirmation Statement?
Yes. Dormant status does not generally remove the requirement to keep Companies House information up to date.
A company normally needs to file a confirmation statement at least once every 12 months, even if there have been no changes.
The confirmation statement helps Companies House confirm that key company information remains correct.
What Happens If a Dormant Company Starts Trading Again?
A company stops being dormant for Corporation Tax purposes when it begins trading or otherwise becomes active.
HMRC must be informed when a dormant company starts trading again. This allows the company to be set up for Corporation Tax and ensures that the correct tax obligations are applied.
Directors should also keep accurate accounting records from the date the company becomes active.
For example, if a company starts selling products, providing services or receiving taxable business income, its accounting and tax responsibilities may change immediately.
What Transactions Can Affect Dormant Status?
Directors should be careful about transactions through the company's bank account.
Examples of activity that could affect dormancy include:
Receiving sales income
Paying business expenses
Paying employee salaries
Receiving investment income
Paying suppliers
Conducting commercial transactions
Receiving interest or other income
Certain administrative transactions may be disregarded when determining whether a company is dormant for Companies House purposes. However, the Corporation Tax position can be different.
This is why businesses should review their circumstances with an accountant rather than assuming that every small transaction is harmless.
What About Accounting and Bookkeeping for a Dormant Company?
A dormant company may have very little bookkeeping, but directors should still maintain appropriate accounting records.
Keeping organised records can help demonstrate why the company qualifies as dormant and make it easier to prepare annual accounts.
Useful records can include:
Bank statements
Share information
Companies House filings
HMRC correspondence
Previous accounts
Confirmation statements
Details of any company transactions
Good bookkeeping also makes it easier to identify when a dormant company becomes active again.
What If HMRC Sends a Tax Return Notice?
If HMRC sends a notice requiring your company to submit a Company Tax Return, do not simply ignore it because the company has stopped trading.
Check the company's Corporation Tax status and determine whether HMRC has officially recognised the company as dormant.
If a return is required, it should be submitted within the relevant deadline. HMRC can impose penalties for late filing.
If the company has genuinely become dormant, contact HMRC to update its status and clarify whether further Company Tax Returns are required.
What Happens If You Want to Close the Dormant Company?
Some directors keep a company dormant because they may want to use it again in the future. Others decide that maintaining the company is no longer worthwhile.
If you want to close the company, you may be able to apply to have it struck off the Companies House register, provided the company meets the relevant conditions.
Before closing a company, directors should check outstanding tax, accounting and filing obligations.
A company should not simply be abandoned because it is not trading.
2026 Dormant Company Compliance Checklist
If your company is dormant in 2026, consider the following checklist:
Confirm whether the company is dormant for Corporation Tax.
Check whether HMRC has issued a notice to file a Company Tax Return.
File dormant annual accounts with Companies House.
File the confirmation statement when due.
Keep appropriate accounting records.
Monitor the company's bank account.
Record any transactions correctly.
Tell HMRC if the company starts trading again.
Keep Companies House information accurate.
Consider professional accounting advice if you are unsure about your obligations.
Why Professional Accounting Support Can Help
Dormant companies may have fewer transactions than trading companies, but their compliance responsibilities should not be overlooked.
An accountant can help determine whether the company is dormant for Corporation Tax, prepare dormant accounts, maintain bookkeeping records and monitor important filing deadlines.
This can be particularly useful if the company previously traded, has outstanding transactions or is expected to restart business activities.
Accurate accounting also helps directors avoid unnecessary penalties and administrative problems.
Final Thoughts
So, does a dormant company need to file a tax return in the UK?
Not necessarily. If HMRC has treated the company as dormant for Corporation Tax and there is no requirement to submit a Company Tax Return, a dormant company generally does not need to file a Corporation Tax return for the dormant period.
However, being dormant does not mean the company has no compliance obligations. Dormant limited companies generally still need to file annual accounts with Companies House and maintain their required company information.
The most important point is to understand the difference between being dormant for HMRC Corporation Tax purposes and being dormant for Companies House purposes.
