Day-trippers will be charged a daily tax of 3 euros ($3.40) for the rest of 2019, starting at a date in May still to be determined. The charge would double next year. But it also would vary on low- and high-traffic days beginning in 2020, with the tax ranging from 3 euros to 10 euros.
The city also adopted more than 20 exemptions to the tax. Among the people who won't have to pay are individuals born, living, working or studying in Venice, children under age 6 and people visiting relatives.
The tax applies to visiting Venice's historic center and any of the lagoon's nearly 50 islands. City officials said it can be paid at transportation and tourism agencies. It will be included in the price of some travel systems, such as a train ticket to Venice Santa Lucia station, and people eligible for exemptions will have a chance to prevent charges.
The city plans to experiment this year on the best ways to enforce the tax, a spokesman said. Scofflaws face fines of up to 450 euros.
