But this is what the MA tax law says "A Massachusetts resident may deduct income received from a contributory annuity, pension, endowment or retirement fund of another state or its political subdivisions if:
the other state has a specific income exclusion for pension income which applies to Massachusetts state or local contributory public employee pension plans; or
the other state has a specific deduction or exemption for pension income which applies to Massachusetts state or local contributory public employee pension plans; or
the other state has no income tax." It's a little confusing
