How to File Accounts at Companies House: What Every UK Business Must Know
Filing annual accounts at Companies House is a legal requirement for every company registered in England and Wales under the Companies Act 2006. This applies whether your business qualifies as a micro-entity, small company, large company, or even a dormant company. Timely, accurate submissions place your company’s key financials and governance statements on public record, underpinning trust with creditors, partners, and HMRC.
As a director, you have a personal legal duty to ensure accounts are submitted accurately and by the deadline. Non-compliance can lead to automatic late filing penalties, currently ranging from £150 to £1,500, and risks your business being struck off the register. Persistent breach could even expose directors to prosecution.
There are three main filing options:
- WebFiling: Most private companies submit accounts online using the secure Companies House portal.
- Software Filing: Many businesses opt for professional accounting software that files directly to Companies House in iXBRL or GAAP-compliant formats. This will soon become mandatory for all.
- Paper Filing: Only allowed in select cases (some LLPs or for reasonable adjustment), but being phased out as Companies House moves to 100% digital filing by 2027.
When Do You Need to File? Understanding Companies House Deadlines
Meeting Companies House deadlines is non-negotiable. Here’s what you need to know:
- Private limited companies: File annual accounts within 9 months after the accounting reference date (ARD)—that’s your “year end.”
- First accounts: Due within 21 months of incorporation.
- Public companies (PLCs): Must file within 6 months of the ARD.
Step-by-step: How to Find Your Company Filing Deadline
- Search for your business on the Companies House Service.
- Note your ARD (displayed as your company’s year end).
- Add 9 months (private) or 6 months (public) to mark your statutory deadline.
- Mark this in your business calendar and set reminders.
| Scenario | Companies House Deadline |
|---|---|
| 1st accounts (new co) | 21 months from incorporation |
| Private company annual | 9 months from ARD |
| Public company annual | 6 months from ARD |
Which Type of Company Accounts Do I Need to File? (Micro, Small, Full & Dormant)
Selecting the right type of accounts isn’t just about saving time—it’s vital to ensure legal compliance and avoid loss of audit exemptions.
| Category | Turnover Max | Balance Sheet Max | Employees Max | Typical Requirements |
|---|---|---|---|---|
| Micro-entity | £632,000 | £316,000 | 10 | Simplified accounts, minimal notes |
| Small Company | £10.2 million | £5.1 million | 50 | Simpler format, audit exemption if eligible |
| Full (Medium+) | Above small limits | Above small limits | >50 | Full disclosures, usually requires audit |
| Dormant | No significant transactions | N/A | 0 | Abbreviated format, no trading |
A company must meet at least two out of the three thresholds for a category. Reassess your position every year, as growth or changes can require upgrading your filing type.
What Information and Documents Do I Need Before Filing Company Accounts?
Gathering the right documents before you start streamlines the process and reduces errors.
| Document / Info | Why It Matters |
|---|---|
| Company number | Verifies your company’s identity for Companies House. |
| Authentication code | Required for secure WebFiling access—never share externally. |
| ARD (“year end” date) | Determines statutory reporting period. |
| Signed balance sheet | Must be signed by a director—shows financial health and accountability. |
| Profit and loss account | Records your trading performance for the year. |
| Directors’ report | Details company activity and governance—often mandatory. |
| Confirmation statement | Required annually, but submitted separately from accounts. |
| Previous year’s accounts | Provides continuity and enables checks for changes/errors. |
| Auditor’s report (if required) | Only for audited companies; confirm if legally needed. |
| Notes to the accounts | Explains accounting policies or figures—required for most entities. |

Step-by-Step Guide: How to File Company Accounts at Companies House Online
Filing online through Companies House WebFiling is now the default, reducing errors and processing times.
Filing Using WebFiling: Authentication & Security
- Register for WebFiling: Head to the Companies House WebFiling portal and sign up using your email address.
- Get Your Authentication Code: This secure, 6-digit code is posted to your registered office after incorporation. You’ll need it for all submissions—request a new code early if misplaced.
- Prepare Accounts: Make sure your accounts are in GAAP or iXBRL format, according to your company’s requirements.
- Log In: Enter your company number and authentication code to unlock your dashboard.
- Input Data Carefully: Manually input required account data, upload a scanned, signed balance sheet, and supporting documents.
- Review Every Entry: Cross-check financials, director details, and dates before submitting.
- Submit and Confirm: Send your accounts. Companies House will email you a receipt and notify you of acceptance.
How to File Micro-Entity or Dormant Company Accounts
Micro-entity and dormant company accounts come with reduced disclosure, but attention to detail is just as important.
- Log in to WebFiling or an approved compatible software platform.
- Micro-entities: Submit minimal disclosures—a simplified balance sheet, basic notes, and directors’ signature.
- Dormant companies: File the dormant company accounts template (if no significant transactions occurred). If the company bank account earns interest or has any trading activity, dormant status cannot be claimed.
- Only use paper filing if you genuinely cannot file online—Companies House is moving to digital-only.
| Account Type | Online Filing Allowed | Audit Exemption | Paper Allowed* |
|---|---|---|---|
| Micro-entity | Yes | Yes | Rare exceptional cases |
| Dormant company | Yes | N/A | Yes, but being phased out |
Common Mistakes When Submitting Annual Accounts—and How to Avoid Them
Avoiding common errors protects your business from fines, rejection, or exposure to regulatory scrutiny.
| Mistake | Risk/Consequence | How to Prevent/Fix |
|---|---|---|
| Missed filing deadline | £150–£1,500 penalty, strike-off risk | Set deadline reminders, use a filing calendar |
| Unsigned balance sheet | Rejection, compliance notice | Scan/sign sheet before upload |
| Wrong accounts category | Filing rejected, compliance issues | Confirm eligibility every year |
| Expired authentication code | Access denied, costly delay | Request new code before it expires |
| Filing on paper (when not allowed) | Risk of missing deadline | Always file online if possible |
| Typos or mismatches in data | Rejection, director accountability | Use review checklist and verify data |
