Thurgau has no statutory tourist-tax law. The applicable official visitor charge is the voluntary TourismusBeitragTG used by participating Thurgau Tourism member businesses: CHF 2.50 per person per night in hotels; CHF 1.50 at campsites, youth hostels, holiday apartments and bed-and-breakfasts. It is not a legally imposed Kurtaxe, is shown separately on the guest invoice, and is subject to 3.8% VAT. The amount is charged regardless of the purpose of the stay and accommodation type where the business participates.
Children up to 16 years are exempt from the TourismusBeitragTG. No other exemption or reduction is specified in the official information. Because this is a voluntary contribution, it applies only at participating member businesses.
No separate short-term-rental rule is published. The voluntary contribution can apply to participating holiday-apartment and bed-and-breakfast businesses, at CHF 1.50 per person per night; it is charged to overnight guests, while children up to 16 years are exempt.
