Tourist taxes: add them before comparing hotel prices
Check whether the booking includes the local tax, who must pay it and how many nights are charged. The rules vary by city.
Before comparing two room prices, check the tourist tax. It may be included in one booking and payable separately in the other. Depending on the place, the charge can be per person, per night, linked to the accommodation category or calculated another way.
Ask the property for the total for your exact guests and dates. A search result showing only the room rate is not necessarily the amount you will pay.
A worked Lisbon example
Lisbon's municipal information lists an overnight tax of €4 per guest aged 13 or over, for a maximum of seven nights per stay. Exemptions have their own conditions.
For two adults staying four nights, that is 2 × 4 × €4 = €32, unless an exemption applies. If the booking already includes and collects it, do not add it again. If it is payable at the property, keep it as a separate line in the budget.
This is a Lisbon example checked on 8 September 2026. Do not copy it into a Nice, Paris or Vienna budget: each destination has its own rules.
What to ask before arrival
Check whether the advertised amount includes the tax and whether the booking platform has already collected it. Confirm any age exemption and the documents needed to claim another exemption.
Ask how payment is taken. Do not assume all properties require cash, or that a request for payment at check-in is automatically suspicious. Compare it with the booking terms and ask for a receipt.
For a long stay, check whether the cap is per stay and how a change of accommodation affects it. A city-wide cap should not be inferred from one hotel's explanation.
If the amount looks wrong
Request a breakdown showing the rate, number of liable guests and charged nights. Compare it with the municipality's current information. A calm calculation is more useful than disputing the tax as an unexpected extra without checking whether it was disclosed.
For the rest of the trip, keep accommodation, food and transport costs separate. It makes changes to the plan easier to price and reduces the chance of counting an included charge twice.
