Dormant Company Accounts in the UK: 6 Key Considerations in 2026

Yes. Dormant companies must file dormant company accounts with Companies House and submit a Company Tax Return only if HMRC requests one. These filings confirm that no significant accounting transactions occurred during the financial year and maintain statutory compliance.

What are dormant company accounts, and why do they matter?

Dormant company accounts are simplified statutory accounts filed at Companies House that record no significant transactions during the accounting period. These accounts confirm a company had no trading activity and keep the company in good legal standing.

Dormant accounts typically include a balance sheet and minimal notes. Directors sign and approve the accounts before filing. Filing prevents late-filing penalties, preserves company name protections, and enables the business to remain ready for future activity. Companies House classifies dormancy under the Companies Act 2006 and uses that status to adjust reporting requirements.

How does a company qualify as dormant?

A company qualifies as dormant when it records no significant accounting transactions during the financial year, excluding permitted items such as payment for shares, fees to Companies House, and penalties.

Permitted transactions include the following examples: share capital transactions when incorporating, payment of Companies House filing fees, and charges from HMRC for late filing. Any other bookkeeping entries, like sales invoices, employee wages, or bank interest credited, can break dormancy. Directors must monitor bank activity and record exceptions to ensure the correct filing status.

What are the filing deadlines and penalties for dormant accounts?

Dormant accounts must be filed at Companies House within nine months of the company’s financial year end; failure to file triggers civil penalties that escalate with delay.

Companies House issues penalties starting at £150 for private companies filed up to one month late. Penalties increase with the duration of the delay. Additionally, persistent failure to file can lead to the company being struck off the register. Directors remain legally responsible for timely filing and must act to avoid enforcement action.

Do dormant companies need to file a Company Tax Return with HMRC?

Dormant companies do not file a Company Tax Return unless HMRC issues a notice to deliver a tax return; if HMRC does, the company must file and confirm dormancy.

When HMRC issues a "Notice to deliver a Company Tax Return," the company must register for Corporation Tax and submit a CT600 form, typically declaring nil trading and explaining dormancy. If the company has never traded and HMRC has been informed, HMRC often records the company as dormant and removes the requirement for annual returns. Directors must notify HMRC in writing when dormancy begins.

Who must sign and approve dormant accounts?

Directors must sign and approve dormant company accounts before filing; a single director may sign for a one-director company, and a qualified accountant can prepare the accounts but not sign on behalf of directors.

Company law requires director approval and signature on statutory accounts. The preparer’s details go into the company records. Audits are normally not required for dormant private limited companies, as the Companies Act provides exemptions when the company qualifies as dormant.

What accounting records must dormant companies keep?

Dormant companies must retain accounting records that show the company’s financial position, including bank statements, invoices for permitted transactions, and records of share transactions, for at least six years.

Statutory record retention aligns with HMRC and Companies House expectations. Records support the dormancy claim during inspections or queries. Examples of essential records: certificate of incorporation, shareholder register, minutes recording dormancy decisions, and copies of filed dormant accounts.

When does dormancy end, and what triggers active filing requirements?

Dormancy ends when the company records any significant accounting transaction, such as sales revenue, employee wages, or bank interest, and then the company must prepare full statutory accounts and register for Corporation Tax.

Examples of triggers: receiving fees for services, hiring staff, or earning interest from bank accounts. Once active, the company must submit full accounts to Companies House, prepare a Company Tax Return, and comply with PAYE and VAT obligations if thresholds are met. Directors must update Companies House and HMRC promptly on status changes.

What are common errors that cause dormancy to be lost?

Common errors include undeclared bank interest, payment of supplier invoices, director loans recorded as transactions, and automatic bank credits such as cashback or refunds.

Directors should monitor small automatic credits and bank fees. For instance, a £2 bank interest credit can classify a company as active. Proper bookkeeping practices identify and classify permitted items versus transactions that break dormancy. Correct classification prevents unexpected compliance obligations.

How much does filing dormant accounts cost, and what services help?

Filing dormant accounts costs range from free if directors file directly to £60–£250 when using accountants or agents to prepare and file accounts, depending on the service scope.

Companies House charges no fee to file accounts using the correct web form, but accountants add professional fees. Service providers often offer packages that include monitoring, preparation, and filing. Choosing a provider depends on the required assurance, record review, and whether directors want outsourced compliance.

How can businesses maintain dormancy efficiently?

Maintain a single company bank account for dormancy, avoid transactional activity, record permitted transactions clearly, and review bank statements monthly to catch accidental credits.

Directors should set bank alerts and restrict account access. Use clear accounting codes for permitted items like share issuance and Companies House fees. Conduct an annual review to confirm continued dormancy before filing. Retain documents proving no trading activity for inspections.
Dormant company accounts confirm a company had no significant transactions during the accounting period. Filing on time avoids penalties and keeps the company legally available for future use. Directors must approve accounts, retain records, and notify HMRC when dormancy begins or ends.

Frequently Asked Questions

Do dormant companies in the UK still need to file accounts?

Yes. Dormant companies still file dormant company accounts with Companies House each year, even when there is no trading activity. My Company Registration treats this as a core compliance task and keeps the filing aligned with UK statutory requirements.

What counts as a dormant company for filing purposes?

A company is dormant when it has no significant accounting transactions during the period. My Company Registration uses this definition to assess whether file accounts for dormant companies apply, while permitted items like Companies House fees do not usually break dormancy.

When must dormant company accounts be filed?

Dormant company accounts are usually due within 9 months of the company’s financial year-end. Missing the deadline can trigger late filing penalties, so My Company Registration tracks the filing date and keeps the dormant company accounts process on schedule.

Do dormant companies need to file with HMRC as well?

Sometimes, yes. If HMRC issues a Company Tax Return notice, the company must respond even if it is dormant for tax and Companies House purposes. My Company Registration uses this distinction to help businesses handle file accounts for dormant companies correctly.

What is included in dormant company accounts?

Dormant company accounts usually contain a simplified balance sheet, relevant statements, and director approval details. The filing is much shorter than full statutory accounts, which makes the dormant company accounts process simpler when the company has had no active transactions.
