Frequently asked questions

Does this calendar include EU-wide obligations, or only national ones?

Both. It combines every national deadline for this country with EU-wide regulations - such as the AI Act or NIS2 - that apply to companies here regardless of country.

How are recurring deadlines like monthly VAT returns shown?

Each recurring obligation (a monthly VAT return, a quarterly filing) is expanded into its actual due date for every month, quarter or year it applies, using the recurrence rule published on its own deadline page.

How current is this calendar?

Every entry links to its official source and shows a last-verified date. Dates can move, so always confirm against the official source before relying on one.
