Pick the parts of UK tax that apply to you and Calcify will turn the main HMRC dates into one clean list. You can also download a basic calendar file to import into Apple Calendar, Google Calendar or Outlook.
It turns scattered HMRC dates into one list that matches your setup instead of everyone else's.
Add prep reminders before filing dates so you are not only reminded on the last day.
Quarterly VAT dates vary by stagger. This tool gives planning prompts, not your exact HMRC account dates.
Source-led from HMRC and GOV.UK guidance on Self Assessment, VAT, Corporation Tax, PAYE year end and Companies House. Always verify exact filing windows in your own HMRC or Companies House account before submitting anything.
