A Boston-based alliance known as the PILOT Action Group claim that the city’s tax-exempt nonprofit institutions aren’t paying their fair share. The group says Boston’s 49 biggest institutions owe the city over $77 million under the PILOT program. While the payments are considered voluntary, all large nonprofit organizations were expected to contribute at a standard level. However, in 2017, institutions like Harvard, Boston College, and Northeastern University paid way less than the amounts requested. The authors of a report on Boston’s PILOT program say the schools can afford to meet their obligations and are shortchanging city residents on services like new bike lanes and playground renovation.
