A group of New York City homeowners filed a lawsuit on Friday arguing that the city had mishandled the rollout of a contentious new tax on the second homes of wealthy out-of-towners. Some owners who are full-time city residents erroneously received letters, according to the lawsuit. The lawsuit, filed in State Supreme Court in Staten Island, does not seek to invalidate the tax. The tax, which is levied as a surcharge on an annual property tax bill, applies to condos and co-ops that are used as second homes and have a “market value,” as determined by the Finance Department, of at least $1 million.
