UK Small Business Tax & Compliance Calendar
Build a tailored planning calendar for your recurring tax, payroll and company-administration deadlines, then export it to your own calendar.
This planner turns standard deadlines into a practical reminder list. It does not replace the deadlines in your HMRC or Companies House accounts: first-year accounts, large-company Corporation Tax, special VAT schemes, payment method and business circumstances can change the date that applies to you.
Select your obligations
Your planning reminders
Review every generated date against your official online accounts before relying on it.
| Date | Reminder | Why it appears |
|---|---|---|
| 15 Aug 2026 | Confirmation statement filing deadline Companies House: Confirmation statement guidance | File within 14 days of the confirmation date shown in your Companies House record. |
| 31 Dec 2026 | Companies House annual accounts deadline GOV.UK: Prepare annual accounts | Established private companies usually file accounts 9 months after their financial year end. First accounts have different rules. |
| 1 Jan 2027 | Corporation Tax payment planning date HMRC: Paying Corporation Tax | For many companies, Corporation Tax is due 9 months and 1 day after the accounting period ends. Different rules can apply, including for large companies. |
Use a calendar for planning, not a substitute for an official account
A calendar is most useful when it is paired with a monthly finance review: reconcile records, set aside tax cash, check documents are complete and look for upcoming payment pressure. Link the result to your cash-flow forecast so VAT, payroll and Corporation Tax do not appear as surprises.
HMRC and Companies House show the actual filing and payment dates for your business. This tool deliberately uses standard planning rules and does not assess penalties, extensions, company size, first accounts or special schemes.
