Companies House and HMRC deadlines for UK limited companies
Kit & Ledger monitors the Companies House and HMRC filing and payment deadlines, and the workplace pension duties, that apply to your UK limited company. This page lists each one, where its date comes from, and what we don't cover yet.
How we decide what applies
We start from your company's live Companies House record, then ask a few questions only you can answer, such as whether you're VAT-registered or run a payroll. Your list contains only the deadlines that apply to you.
Where Companies House publishes your deadline, we use its date unchanged. Where nobody publishes one, as with Corporation Tax and VAT, we work it out from the official rule and the dates you confirm.
If we don't have enough information to work a date out reliably, we show Needs information instead of guessing, and we don't send reminders for it until it's resolved.
Companies House
| Deadline | Where the date comes from | When it applies |
|---|---|---|
| Confirmation statement | Read from your company's live Companies House record and shown exactly as Companies House publishes it. | Every company we support. Shown in the free check, then monitored once you subscribe. |
| Annual accounts | Read from your company's live Companies House record and shown exactly as Companies House publishes it. | Every company we support. Shown in the free check, then monitored once you subscribe. |
| Changes to your company's record | We check your Companies House record each day and email you about changes to your registered office address, directors and company secretary, people with significant control, and company status. | Every monitored company. These are changes, not deadlines, so they arrive as notifications rather than reminders. |
HMRC
| Deadline | Where the date comes from | When it applies |
|---|---|---|
| Corporation Tax payment | 9 months and 1 day after the end of the accounting period you confirm. | Companies that don't pay Corporation Tax in quarterly instalments. |
| Company Tax Return (CT600) | 12 months after the end of the accounting period you confirm. | Companies that need to file. A dormant company that HMRC hasn't asked to file doesn't. |
| VAT return and VAT payment | 1 calendar month and 7 days after the end of each VAT period. If you pay by Direct Debit, we also show when HMRC expects to collect. | VAT-registered companies on monthly or quarterly returns, with periods that end on the last day of a month. |
| PAYE payment | The 22nd, after each tax month or tax quarter ends. | Employers who pay HMRC electronically, monthly or quarterly. |
| Full Payment Submission (FPS) | On or before each payday, from the pay schedule you give us. | Companies that run payroll. |
| Employer Payment Summary (EPS) | By the 19th of the following tax month. | Only for a month when you tell us you need to send one. |
Until you confirm your Corporation Tax accounting period end, we can only show estimated Corporation Tax deadlines, and we don't send reminders for them.
Workplace pensions (The Pensions Regulator)
| Deadline | Where the date comes from | When it applies |
|---|---|---|
| Declaration of compliance | Within 5 months of your duties start date, which you confirm. | Companies with workplace pension duties, for example because they employ staff. |
| Re-enrolment and re-declaration | Every three years, from the dates you confirm. | Companies with workplace pension duties. |
Reminders
For most deadlines we can monitor, we email you 30 days, 7 days and 1 day before they're due. Short-cycle deadlines use a shorter schedule suited to the time available. If you subscribe close to a deadline, you'll get whichever reminders are still ahead.
Reminders go to the email address you choose, and you can change it in Manage your account.
The free check shows your confirmation statement and annual accounts dates. HMRC and pension deadlines are added once you subscribe and answer a few questions about your business.
What isn't covered yet
Kit & Ledger is built for UK private limited companies that are active on the Companies House register, are owner-managed and have roughly 0–10 employees.
- PLCs, LLPs and other company types aren't supported yet.
- Some registered business activities can need specialist tax or regulatory treatment. If yours does, the free check tells you.
- Within the deadlines above, we don't calculate dates for Corporation Tax paid in quarterly instalments, the VAT Annual Accounting Scheme, VAT payments on account, VAT periods that don't end on a month end, or PAYE paid by a non-electronic method. Where one of these applies, the deadline shows as Needs information.
- We only monitor the deadlines listed on this page. Other obligations, such as the ICO data protection fee or employers' liability insurance, aren't covered.
Kit & Ledger is an organisational tool, not an adviser. For how we build and check the rules behind these dates, see our Source & Verification Framework.
