 New Haven has sent a property tax bill to a Whaley Avenue building owned by the Church of Scientology for the first time in 14 years. The religious group bought the former Hallux building in 2003 with plans to convert it into a house of worship, but it never happened. Church ownership granted the building tax-exempt status, but the building is not being used for religious purposes. Scientology has now been billed over $79,000 in property taxes with half due this month and the rest due in January.
