Which state to file irrevocable lving trust income?

Have a situation w/ an irrevocable living trust (has EIN) that will have undistributed income.  Trying to determine which state (if any) the income needs to be reported.

The trustee is a resident of MA.  The beneficiary and grantor are residents of CO.  The trust will not generate any income directly from either state and looking at the resident trust rules from both states, the trust doesn't seem to fit as a resident trust of either MA or CO.  Is it possible that the trust won't have to file state income in either state?
