What happens if I file my annual accounts late?

Late filing penalties range from £150 for accounts up to 1 month late, to £1,500 for accounts more than 6 months late. Companies House may also start compulsory strike-off proceedings if accounts are significantly overdue.

How do I calculate my annual accounts filing deadline?

Add 9 months to your company's accounting reference date (year-end). For new companies, the first accounts deadline is either 21 months from incorporation or 3 months after the first accounting reference date, whichever is later.

Can I change my accounting reference date?

Yes, you can change your accounting reference date by filing form AA01 with Companies House. However, you can only shorten your accounting period once every 5 years without special permission.

What's included in annual accounts?

Annual accounts typically include a balance sheet, profit and loss account, notes to the accounts, and a directors' report. Micro-entities may file abbreviated accounts with just a balance sheet.

Do dormant companies need to file accounts?

Yes, dormant companies must still file annual accounts and a confirmation statement with Companies House, though they may qualify for dormant company accounts which are simpler to prepare.

How does GoForma help with annual accounts filing?

GoForma's accounting packages include annual accounts preparation and filing, with dedicated accountants handling the entire process and proactive reminders to ensure you never miss a deadline.

Can I file annual accounts myself?

Yes, you can file accounts yourself through Companies House WebFiling service, but professional preparation ensures accuracy, compliance with accounting standards, and maximises available reliefs and allowances.

The company accounts filing deadline for UK limited companies is 9 months after the company's year-end date, with late filing resulting in automatic penalties from Companies House starting at £150, making timely submission crucial for avoiding unnecessary costs and maintaining good standing with HMRC and Companies House.
