This calendar lists every deadline that applies to a company in Estonia 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.
