Does anybody know of affordable tax prep software for a very small business that enables a partnership to e-file in Massachusetts? Specifically, my son needs to file Massachusetts Form 3 (the MA equivalent of the federal 1065) for an LLC. Apparently, they are required to e-file because they have at least one out-of-state partner. He is having a hard time finding what he needs. He talked to a couple of the big ones (including TurboTax), but their software does not support this. It looks like Taxworks might have it, but at a prohibitively high price. TIA.
