The accommodation price is not always the complete overnight total. Andorra applies an accommodation tax at regulated tourist properties, with a rate that varies by category and a separate IGI calculation.
The clock stops at seven
Age changes the room arithmetic
The official visitor information applies the tax from age 16. A family should therefore calculate the taxable guests, not simply multiply the room count by the number of nights.
Category changes the nightly rate
Five-star accommodation, four-star properties, tourist-use housing, two- and three-star accommodation and other regulated stays sit in different bands. Confirm the property's official category rather than guessing from the booking site's presentation.
The tax and IGI are separate lines
Andorra's official notice states that 4.5% IGI is added to the tourist-tax amount. A booking page that says "taxes may be payable at the property" deserves one precise question before arrival.
Eight nights do not create eight taxable nights
The charge is capped at seven nights for one stay. Longer stays should not keep extending the same tax clock indefinitely, although a new booking arrangement may need confirmation with the accommodation.
Turn a vague extra into a known number
Ask the property for the nightly rate, number of taxable guests, number of taxable nights and whether IGI is already included. Four small facts convert a surprise at checkout into a planned line in the travel budget.
