Tax and compliance calendar 2026 for companies in Estonia

This calendar lists every deadline that applies to a company in Estonia in 2026: 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.

Pay Transparency: baseline duties (pay ranges, no salary-history questions, right to pay information) apply to every employer

Directive (EU) 2023/970 requires every employer in the EU, whatever its size, to give job applicants the initial pay or pay range for the role before the interview or in the job ad, and bans asking applicants about their pay history. Workers also get the right to ask, in writing, for their own pay level and the average pay level by sex for people doing the same or equal-value work.

Removal of the €150 customs duty-exemption threshold: transitional flat-rate duty on low-value parcels

Until mid-2026, parcels worth up to €150 sent to EU consumers from outside the EU were exempt from customs duty (VAT has already been due on them since 2021). Council Regulation (EU) 2026/382 removed that exemption and, from 1 July 2026, applies a flat transitional duty of €3 per item to such low-value consignments, ahead of full ad-valorem tariffs once the EU Customs Data Hub is operational (targeted around mid-2028).

Cosmetics: expanded fragrance-allergen labelling (26 to 80+ allergens) mandatory on new products

The Cosmetic Products Regulation's list of fragrance allergens that must be individually named on the label grows from about 26 to more than 80 substances, whenever present above 0.001% in leave-on products or 0.01% in rinse-off products. New cosmetic products placed on the market from 31 July 2026 must use the expanded list; stock already on the market before that date can still be sold until 31 July 2028.

Right to Repair Directive applies: manufacturers must repair on request; repaired goods get 12 extra months of guarantee

Directive (EU) 2024/1799 applies nationally from 31 July 2026. Manufacturers of products with EU repairability requirements (washing machines, fridges, dishwashers, vacuum cleaners, displays, phones, tablets, servers, e-bike batteries) must repair them at a reasonable price and time even outside the legal guarantee. When a consumer chooses repair under the guarantee, the guarantee is extended by 12 months. Sellers must offer repair when it is not more expensive than replacement.

Packaging and Packaging Waste Regulation: core obligations apply (minimisation, PFAS ban in food packaging, conformity documentation, EPR registration)

Regulation (EU) 2025/40 applies directly in all Member States. Packaging must be minimised (e-commerce parcels max 40% empty space), food-contact packaging with PFAS above limits is banned, every packaging type needs a conformity assessment and technical documentation, and producers must register for extended producer responsibility in each country where they place packaged goods. Further deadlines follow (harmonised labels 2028, recycled-content minimums 2030).

Empowering Consumers for the Green Transition: ban on vague/unsubstantiated environmental claims applies

Directive (EU) 2024/825 amends EU consumer-protection law (the Unfair Commercial Practices Directive and the Consumer Rights Directive) to ban generic environmental claims not backed by recognised excellent environmental performance (e.g. 'climate neutral', 'eco-friendly', 'green' used without substantiation), bans claims based purely on carbon-offsetting, and requires sustainability labels to come from a certification scheme or a public authority rather than being self-created. It also bans planned-obsolescence practices and requires clearer product durability/reparability information.

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.
