How to File Dormant Company Accounts in the UK 2026?

Yes — My Company Registration can file dormant company accounts for UK companies and submit them to Companies House and HMRC, managing statutory deadlines and compliance on your behalf.

What is the process to file accounts for a dormant company with My Company Registration?

Filing dormant company accounts requires preparing abbreviated or micro-entity accounts, confirming no significant transactions, and submitting accounts to Companies House by the statutory deadline; My Company Registration handles preparation, validation, and submission.

A dormant company files simplified accounts that show no significant accounting transactions during the reporting period. The process begins with confirming dormancy under the Companies Act 2006 definitions and checking that the company made only permitted transactions, such as director fees, share allotments, or statutory filing fees. My Company Registration validates transaction records, compiles the correct format (micro-entity or small-company accounts when applicable), and prepares the Companies House submission using the company’s authentication details.

How long does it take to file dormant company accounts?

Typical turnaround is 5–15 business days from receipt of complete records; urgent 24–72 hour services are available when statutory deadlines are imminent.

Simple dormant accounts require minimal accounting work if the records are complete. Common time drivers include verifying director signatures, confirming permitted transactions, and obtaining client approval. Complex cases—late filings, previous non-compliance, or reconciliation—extend timelines. My Company Registration offers clear deadline tracking, expedited submission options, and confirmation once Companies House accepts the accounts.

What documents does My Company Registration need to file for dormant accounts?

Provide the company registration number, accounting reference date, director details, confirmation of dormancy, and bank or transaction statements showing no significant transactions.

Clients supply core identity and filing data. My Company Registration uses three verification steps: confirm company identity with Companies House records, validate director details against submitted ID or Companies House entries, and review bank statements for excluded transactions. If permitted transactions exist, the team records them as reconciled items to maintain a clear audit trail.

Which account format should a dormant company use?

Choose micro-entity accounts when eligible; otherwise, use small-company abridged accounts; both formats report minimal figures and a director’s statement on dormancy.

Micro-entity accounts present the briefest disclosures: balance sheet and notes with prescribed formats. Small-company accounts include a simplified profit and loss and balance sheet but still allow reduced disclosures. My Company Registration assesses eligibility using thresholds: turnover under £632,000, balance sheet total under £316,000, and fewer than 10 employees for small-company status. The team selects the compliant format and adds the required director’s statement confirming dormancy.

What are common filing errors, and how are they avoided?

Errors include incorrect account format, missing director’s statement, and unreported transactions; My Company Registration prevents these through checklist validation and Companies House pre-submission checks.

Common mistakes result from misunderstanding permitted transactions or misclassifying minor activity as significant. The firm uses a three-stage validation: document intake, statutory compliance check against Companies House guidance, and a final client review. This workflow reduces rejection risk and minimises late-filing penalties by ensuring accounts meet statutory formatting and signature requirements.

What penalties apply for late dormant accounts?

Late filing penalties start at £150 for private companies, escalating with the length of delay; persistent non-filing can lead to prosecution and company strike-off.

Companies House issues fixed penalties based on days late. For private companies, penalties range from £150 (up to 1 month late) to £1,500 (over 6 months late). Continued non-compliance triggers increased enforcement, including prosecution. My Company Registration monitors deadlines, issues early reminders, and offers expedited filing to avoid fines.

How does filing dormant accounts affect Corporation Tax returns?

Dormant status removes Corporation Tax filing obligations when no taxable business activity exists; My Company Registration confirms HMRC dormant status and files necessary notifications.

Companies must notify HMRC if they are dormant for Corporation Tax. If HMRC records show dormancy, no tax return is required. My Company Registration verifies HMRC status and submits any required notifications. If HMRC queries arise, the team prepares supporting documentation showing no taxable transactions.

Can dormant companies file online or by post?

Companies House accepts both electronic and paper filings; electronic filing is faster and provides immediate rejection/acceptance feedback.

Online filing uses Companies House WebFiling or compatible software. Electronic submissions shorten processing time and provide an electronic receipt. Paper filings require postal time and carry a higher rejection risk for formatting errors. My Company Registration prefers electronic submission and manages authentication using the company’s WebFiling credentials or agent authorisation.

What evidence demonstrates dormancy during an accounting period?

Evidence includes bank statements showing only permitted transactions, copies of statutory filings, a signed director’s statement, and board minutes confirming inactivity.

Permitted transactions include payment for shares, filing fees, and penalties. My Company Registration cross-checks bank activity against these categories, prepares board minutes or director statements when missing, and compiles a supporting pack to place on record. This pack provides citation-ready evidence to respond to HMRC or Companies House queries.
