01 / How it works

One input, every deadline.

Modelled on the actual rules HMRC and Companies House apply, not a generic small-business calendar.

UK limited companies have to track at least seven separate cycles of deadlines: accounts, Corporation Tax, VAT, PAYE, P11D, Confirmation Statement, and (from April 2026) Making Tax Digital for Income Tax for property landlords above £50k. Most owners keep this in three browser tabs and a calendar reminder.

Tell us your year-end and a couple of yes/no questions. We map every deadline that flows from those answers into one calendar, dated to your company, exportable as .ics so your calendar app handles the alerts.

02 / Your details

Tell us about your company.

Just enough to map the deadlines accurately. Nothing leaves your browser.

When does your accounting year end? Most UK Ltds default to 31 March or 31 December. Check your last set of accounts.

If you turn over more than £90,000 in any rolling 12 months, registration is mandatory. Voluntary registration below threshold is also common.

Including yourself if you draw a salary as a director through the company payroll.

From April 2026, MTD for Income Tax applies to landlords (and sole traders) with combined gross income over £50,000. Quarterly digital updates required.

The month your CS is due each year, usually the anniversary of incorporation. Skip if unsure.

This calendar is built from the standard UK Ltd compliance rules as of April 2026. It assumes a standard 12-month accounting period, no late filing penalties applied, and standard VAT stagger groups. Confirmation Statement dates, P11D obligations, and Self Assessment dates depend on your exact circumstances. For a high-stakes filing, confirm with your accountant or check directly via gov.uk and Companies House. Educational tool, not tax advice.
