What is a micro-entity?
Your UK limited company qualifies as a micro-entity if it meets at least two of the three thresholds in the Companies Act 2006 s384A: turnover not more than £1m, balance-sheet total not more than £500k, and not more than 10 employees on average. Most owner-director and contractor companies meet this.
What you must file
- Statutory accounts under FRS 105 (simplified) — filed with Companies House within 9 months of your year-end.
- Corporation Tax return (CT600) — filed with HMRC within 12 months of your year-end; tax payable within 9 months and 1 day.
- Confirmation statement (CS01) — annually, within 14 days of the review date.
Penalties for late filing
Companies House charges £150 (≤1 month late) rising to £1,500 (≥6 months). HMRC charges £100 immediately, another £100 after 3 months, and tax-geared penalties after 6 and 12 months. Directors can also be disqualified for persistent lateness.
A clean filing checklist
- Full 12-month bank statements (all business accounts).
- Sales invoices raised in the year.
- Expenses / purchase invoices and receipts.
- Dividend vouchers and board minutes.
- Last year’s filed accounts and CT600 (if any).
