Regular readers of this blog are familiar with the tax competition battle, which largely revolves around high‐​tax governments attempting to track — and tax — economic activity that migrates to lower‐​tax jurisdictions. But this is not just a global fight between decrepit welfare states such as France and fiscal havens such as the Cayman Islands. American states also compete with each other, and there are numerous examples of high‐​tax states such as California and New York trying to grab money from people who escape to zero‐​income tax states such as Nevada and Florida. The fight even exists at the local level, and a good example is the attempt by politicians to tax faraway online travel agencies. The Orange County Register opines about these extraterritorial tax grabs:

A recent legal victory for some Texas cities against online travel companies over hotel taxes may have given Anaheim officials hope for their own case, but they shouldn’t start celebrating just yet. Other cities have not fared as well in similar lawsuits. …Here’s what Fairview Heights, Anaheim and other cities wanted to change: In a typical transaction, a traveler picks a hotel and books a room, stays there, and pays the hotel a room charge plus a local occupancy tax based on the room charge. The hotel keeps the room charge and forwards the tax money to the government. Enter online travel companies like Expedia, Hotels​.com, Orbitz, Priceline and Travelocity, which allow travelers to sort through hotels and book a room on a central Web site. These companies do not reserve or resell hotel rooms, but act as intermediaries to facilitate the transaction between hotel and traveler. The hotel receives an amount for the room, on which the city’s hotel tax is based. Let’s say I search a Web site and book a $100 hotel room. The online company charges me $10 for their service. Anaheim argues that hotel occupancy tax should be paid not only on the $100 room charge, but also on the $10 service fee. …A federal bill is pending to limit hotel taxes to amounts collected by a hotel for occupancy purposes, excluding service fees and markups by intermediaries. The Constitution permits Congress to pass such laws if there is a danger that state and city laws are interfering with interstate commerce. Hotel taxes are attractive to local politicians because they are a way to shift the tax burden to “outsiders.” But because every U.S. city has a hotel tax, we’re all somebody else’s “outsider.” The net result is that everyone is taxing everyone else in an unaccountable way, and unless the cities and their lawyers are stopped, in an unpredictable way, too.
