Are retirement pensions taxable in MA?

[TomK]

"Income from most private pensions or annuity plans is taxable in Massachusetts. Certain government pensions, however, are exempt under Massachusetts law. In general, exempt pensions include contributory pensions from the U.S. Government or the Commonwealth of Massachusetts and its political subdivisions, and noncontributory military pensions."
