Massachusetts currently mandates e-filing the M-990T and MA PC, however they only allow e-filing through the "MassTaxConnect" website.
At present, they do not support submissions from third-party Software Providers through the IRS Modernized Electronic Filing (MeF) service, which means that as of now, CTRAC will not be able to support E-File for Massachusetts. Once the MA DOR approves third-party IRS MeF, we will revisit offering the M-990T e-file option.
