This should clear up any confusion you have regarding 1099's, Massachusetts, and the Federal Government in respect to tax laws.

As you can clearly see that outlined in Subsection 3 paragraph 4 this is clearly a state 1099 not a federal 1099.
Payments subject to Massachusetts reporting but not to federal reporting
Where a TPSO has a Massachusetts Form 1099-K reporting obligation but is not required to file Form 1099-K with the IRS, a TPSO may file with the Department using Massachusetts Form 1099-K or IRS Form 1099-K.
Further more under said program using the state DOR program
Submission of Forms 1099-K to DOR using the Combined Federal/State Filing Program
Where amounts paid in settlement to a payee in a calendar year meet both the IRS and Massachusetts Form 1099-K thresholds, a TPSO may use the Combined Federal/State Filing Program to file Form 1099-K with the Department. Where amounts paid in settlement in a calendar year to a payee meet the Massachusetts threshold but not the IRS threshold, a TPSO should submit Form 1099-K to the Department directly using MassTaxConnect (MTC).
