UK COMPANY ACCOUNTS FILING
MicroFiler files confirmation statements online for a fixed fee of [£XX] plus the £50 Companies House digital filing fee, with submission completed within one to two working days of receiving your details.
THE PROCESS
A confirmation statement is the annual filing UK limited companies and LLPs submit to Companies House to verify that the public register holds accurate company information. It replaces the old annual return (form AR01) and is filed on form CS01 for companies or LL CS01 for LLPs.
It is separate from annual accounts and the corporation tax return as these are three distinct filings with three different deadlines. Filing a confirmation statement does not involve any financial information; it is purely a register-of-companies update.

SERVICE SCOPE
Our confirmation statement filing service covers the full CS01 submission process, from reviewing your existing Companies House record to confirming acceptance with you by email. You provide the latest details for any changes, and we handle every step of the submission.
Before filing, your current Companies House record is reviewed to identify any details that may need updating. Common items checked include directors and secretaries, registered office address, registered email address (mandatory since March 2024), shareholders, share capital, and SIC codes describing the nature of business.
Any changes to directors, shareholders, or people with significant control (PSCs) are submitted as part of the confirmation statement. Where appointments, resignations, or PSC changes need to be filed separately on forms AP01, TM01, or PSC01, we file those alongside the CS01 to keep your record fully current.
SIC codes describe the nature of your company's business and are confirmed each year on the CS01. Where your activities have changed, new SIC codes are selected from the Companies House list and submitted with the confirmation statement.
The CS01 form is prepared with your confirmed details and submitted online to Companies House through our authorised agent account. Submission is usually accepted within minutes; in practice, the digital service rejects only filings with incomplete identity verification or unresolved register inconsistencies.
The £50 Companies House digital filing fee is paid as part of our service and itemised on your invoice. You do not pay Companies House directly, one invoice covers both the service fee and the statutory fee.
WHO NEEDS TO FILE
Active limited companies file a confirmation statement annually to confirm directors, shareholders, PSC details, and registered office. The statement is filed in addition to annual accounts and the corporation tax return, on a separate deadline.
Active limited companies file a confirmation statement annually to confirm directors, shareholders, PSC details, and registered office. The statement is filed in addition to annual accounts and the corporation tax return, on a separate deadline.
Dormant limited companies must file a confirmation statement every year, even with no trading activity. A company struck off the register for failing to file a confirmation statement loses its registered status and any assets pass to the Crown as bona vacantia, regardless of whether it was dormant or trading.
Limited liability partnerships file a confirmation statement on form LL CS01, covering members, designated members, and PSC details. Community interest companies (CICs), limited partnerships, and Scottish limited partnerships have equivalent annual filing obligations.
KEY DATES
The confirmation statement is due once every 12 months, with a 14-day filing window after the end of each review period. Companies that miss the window face strike-off action, not financial penalties, which makes the deadline more urgent than late accounts filings in practical terms.
The confirmation date is the anniversary of your company’s incorporation, or the anniversary of your last confirmation statement, whichever is later. A company incorporated on 15 June 2024 has a first confirmation date of 14 June 2025 and an annual filing window opening on that date each year.
You have 14 days after the confirmation date to file the statement. Filing on the confirmation date itself or earlier is permitted. The 14-day window is firm as Companies House does not extend it for individual companies.
A newly incorporated company files its first confirmation statement no later than 14 days after the first anniversary of incorporation. The first confirmation statement is identical in form and content to subsequent statements; there is no simplified version for new companies.

HOW IT WORKS
Filing a confirmation statement requires confirmation of 6 categories of information held on the public register. Any changes since the last filing are submitted alongside the CS01.
1
We collect your company and director details, run anti-money-laundering identity checks, and send your engagement letter for signing. Setup completes within one to two working days.
2
Share your bookkeeping records by email or invite us into your accounting software (Xero, QuickBooks, FreeAgent). Bank statements and invoice copies are sufficient without accounting software.
3
A dedicated accountant prepares your statutory accounts and calculates your corporation tax. Most micro and dormant company filings complete within 3 to 5 working days.
4
Draft accounts and CT600 are sent to you for approval. Once approved by email, we file directly with Companies House and HMRC and send you the confirmation receipts.
WHAT YOU'LL NEED
Filing requires complete financial records of your company’s transactions for the accounting period. The seven record types below cover most micro and small company filings.
Records can be sent as PDF email attachments, shared from cloud storage, or made available through your accounting software.
LATE FILING
Late filing triggers automatic financial penalties from both Companies House and HMRC. Penalties apply even when no corporation tax is due, and they increase the longer the filing remains overdue.
Companies House late filing penalties
Penalties double if accounts are filed late in two consecutive years. Persistent late filing can lead to the company being struck off the register.
A micro company is a UK limited company that meets at least two of three conditions: annual turnover of £632,000 or less, balance sheet total of £316,000 or less, and 10 or fewer employees. Micro companies file simplified accounts under FRS 105 with reduced disclosure.
Dormant companies are not normally required to file a CT600 if HMRC has formally confirmed dormant status. They must still file dormant accounts (form AA02) with Companies House every year to stay on the register.
Companies House and HMRC accept direct filings from company directors. Most directors use an accountant because the iXBRL tagging, CT600 computations, and capital allowance claims require accounting software and tax knowledge.
Most micro and dormant company filings complete within 2 to 7 working days from the date your records reach us. Small companies and those with complex transactions may take longer, but the timeline is confirmed at onboarding.
Annual accounts report your company’s financial activity for the year and are filed with both Companies House and HMRC. A confirmation statement updates Companies House on your registered details including directors, shareholders, and registered office. Both are mandatory but filed separately.
Yes. Switching is straightforward — your new accountant contacts your previous one and arranges secure transfer of records. There is no fee or penalty from HMRC or Companies House for changing agents.
No. The fixed fee covers the full filing service regardless of when records arrive. Late records may push completion beyond the standard 7-day window, but the price remains the same.
HMRC requires a company to register for corporation tax within 3 months of starting to trade. Late registration triggers a £100 penalty and may attract further enquiries. We handle backdated registration as part of onboarding for new clients in this position.
