Slovak Advertising Rules 2026: How They Differ from Austria

30-second takeaway: Slovakia has no advertising tax (Austria: 5%), stricter language requirements for mass-market ads, and different rules for misleading advertising, health claims, and comparative advertising. Expanding from AT to SK? Know these 4 points.

1. Advertising tax: AT 5%, SK 0%

The biggest underrated difference. Austria charges 5% advertising tax on paid advertising services — adyoutiser adds it automatically on bookings on Austrian screens. Slovakia has no equivalent.

A €5,000 Vienna campaign costs €250 extra. Bratislava: €0. On cross-border bookings, tax applies only to the AT portion — automatically calculated on our platform.

2. Language rules: SK stricter for mass-market

Slovakia's State Language Act requires mass-market advertising to be primarily in Slovak. English, German, and others are allowed — but the main message for the general public should be Slovak.

Works: multilingual tourism ads, B2B in English, brand names in any language. Problem: German or English mass-market at commuter sites without Slovak version.

3. Health claims, alcohol, gambling

Health claims are EU-regulated, but SK enforces stricter at national level. Functional foods, supplements, and cosmetics claims need local legal review before SK launch.

Alcohol: allowed with limits, school proximity matters. Gambling: SK has separate licensing for advertising providers.

4. Comparative and misleading advertising

Both follow EU directives. SK consumer protection authority (SOI) is more active on cross-border ads with price comparisons, "best in SK" claims, and comparisons against local competitors.
