Harvard doesn't have to pay tax but Harvard and MIT have made tens of millions of dollars in "voluntary" contributions to the municipalities they reside in over the last decade. The situation is weird but Harvard and MIT give enough money to make property tax in Cambridge dirt cheap. I'm only paying ~0.375% for example.
