Klarbon keeps the start date of every e-invoicing and e-reporting obligation it tracks, country by country, each with its official source. This page puts those dates in the calendar you already use, and gives you the same register as data. Subscribe once: when a date moves in the register, it moves in your calendar.

What is in the calendar?

One all-day event for each obligation with a date, in law or announced: who must receive, send or report e-invoices, and from when. Each event says whom it covers and links the official source and Klarbon's guide to the country. A date from a bill or a government announcement is marked as not yet law. Dates that have passed stay in, so the calendar shows the whole timeline, not only what comes next.

Which calendar apps work?

Google Calendar, Outlook and Apple Calendar subscribe in one step. Any other app that reads iCalendar (.ics) files can subscribe to the file's address, or import the file once.

What does it not tell me?

Whether a date applies to your own business. Am I affected? answers that in up to five questions, and e-invoicing by country has the rules in full. None of this is tax advice.

Use the data

The same register as data: one row per obligation, with its official source and the date the source was last read. The files change only when the register does.
