The Jersey Shore, a storied summer vacation spot, has become the newest national battleground over regulating and taxing the internet economy.

New Jersey is one of the first big states to adopt a surcharge on short-term rentals — a so-called Airbnb tax. It kicked in Oct. 1 and is causing vacationers to rethink their summer travels and stirring anxiety among the homeowners who rely on them.

The fallout over the 11.6 percent tax has inserted New Jersey into a broader debate as states and communities grapple with the explosive growth of the online home-sharing economy. A patchwork framework of local ordinances has failed to keep pace with the rapid rise of Airbnb, the largest home-sharing site, which was valued at $31 billion two years ago and has upended the rental market around the world.

Much like Uber’s dominance has caused a regulatory challenge for cities and Amazon’s ascent has prompted states to adopt internet sales taxes, the popularity of Airbnb has begun to push lawmakers to impose new rules even as they find ways to tap the enormous revenue it generates.
