Direct answer
The main UK limited company deadlines to track are annual accounts, confirmation statements, Corporation Tax payment and Company Tax Returns. Some companies also need VAT, PAYE, pensions or industry-specific reminders.
Limited companies often need separate reminders for Companies House accounts, confirmation statements, Corporation Tax payment and Company Tax Returns.
Companies House deadlines
Annual accounts are filed with Companies House. Confirmation statements are also filed with Companies House to confirm key company information remains accurate.
The first accounts deadline is usually 21 months after registration, while later annual accounts are usually due 9 months after the financial year ends.
HMRC deadlines
Corporation Tax payment is usually due 9 months and 1 day after the accounting period ends for companies with taxable profits up to GBP 1.5 million.
The Company Tax Return deadline is 12 months after the end of the accounting period it covers.
