Tax and compliance calendar 2028 for companies in the EU
This calendar lists every deadline that applies to a company in the EU in 2028: national tax and reporting duties alongside EU-wide regulations - such as the AI Act, NIS2 and the Cyber Resilience Act - that apply across the whole EU.
Recurring obligations - monthly VAT returns, quarterly filings, annual reports - are expanded into their individual due dates for the year using the rule shown on each deadline's own page. This calendar does not shift dates that fall on a weekend or public holiday; always check the linked official source for the exact filing deadline.

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.
