UK compliance,
handled end to end.
A UK limited company has more than a dozen statutory deadlines a year across Companies House and HMRC. We map every one of them, prepare and review every filing, and submit on time, so you never pay a late penalty again.
What is due, when, and what it costs to miss
The main obligations for a UK limited company. We track each one for you and send reminders well before every deadline.
| Obligation | Who it applies to | When it is due | If it is late |
|---|---|---|---|
| Annual accounts Companies House | Every limited company | 9 months after the financial year end (first accounts: 21 months after incorporation) | £150 to £1,500 depending on how late, doubled if late two years running |
| Confirmation statement Companies House | Every company | At least once every 12 months, within 14 days of the review date | Filing fee £50. Not filing is an offence and can lead to the company being struck off |
| Director identity verification Companies House | All directors and people with significant control | Existing directors by 18 November 2026. New directors before they are appointed | An appointment without verification is not valid, and it is an offence not to verify |
| Corporation Tax payment HMRC | Companies with taxable profits | 9 months and 1 day after the year end for most companies | Interest charged from the due date |
| Company Tax Return (CT600) HMRC | Every company, even with no profit | 12 months after the year end | £200, another £200 at 3 months, then 10% of unpaid tax at 6 and 12 months. £1,000 each if late three times running |
| VAT returns HMRC, Making Tax Digital | VAT registered businesses (registration required above £90,000 taxable turnover) | Usually 1 month and 7 days after each quarter | Penalty points for late returns, then a financial penalty once the points limit is reached, plus late payment charges |
| Payroll (RTI) HMRC | Every employer, including director only payrolls | On or before each payday | £100 to £400 every month, depending on employee numbers |
| PAYE payment HMRC | Every employer | 22nd of the following month if paid electronically | Late payment penalties and interest |
| Self Assessment HMRC | Directors and individuals with untaxed income | 31 January after the end of the tax year (online) | £100 immediately, rising the longer it is late |

Three changes UK businesses need to act on now
Companies House identity verification deadline
Every existing director and person with significant control must have verified their identity by this date. New directors must verify before they are appointed. We can check your company's status and guide each director through verification.
IFRS 18 comes into force
Every IFRS reporter must present the income statement in five new categories, with restated 2026 comparatives. Read our IFRS 18 guide.
Making Tax Digital for Income Tax
Sole traders and landlords must keep digital records and send quarterly updates to HMRC. It started in April 2026 for gross income above £50,000, extends to above £30,000 from April 2027 and above £20,000 from April 2028.
