What every limited company must file
Running a limited company — even a one-person company with modest income — comes with fixed annual filing duties. Whatever your size, an active company must deliver:
- Annual (statutory) accounts to Companies House, normally due 9 months after your accounting year end
- A Company Tax Return (CT600) with full accounts and tax computations to HMRC, due 12 months after the end of the accounting period
- Corporation Tax payment, due 9 months and 1 day after the end of the accounting period
- A confirmation statement (CS01) to Companies House at least once every 12 months — even if the company is dormant
Miss a deadline and automatic penalties apply — Companies House late filing penalties start at £150 and rise to £1,500 for a private company, separate from HMRC penalties for a late tax return.

Who this hub is for
Our limited company guidance is written for the companies that make up the vast majority of the UK register: micro companies and small companies, single-director companies, owner-managed businesses, contractors and consultants trading through a limited company, freelancers, start-ups and dormant companies. If your company has a finance team and an audit requirement, you’re beyond the scope of these pages — for everyone else, this is written for you.
Also running the company through Making Tax Digital?
Making Tax Digital for Income Tax applies to sole traders and landlords, not to limited companies — but many directors also have rental or self-employed income, and VAT-registered companies already file VAT under MTD rules. See MTD for limited companies for how the two regimes fit together.
