The New York State Department of Taxation and Finance has announced it is now accepting e-filed 2015 partnership returns containing Forms IT-204.1, New York Corporate Partners' Schedule K, and IT-204-CP, New York Corporate Partner's Schedule K-1. If a partnership with corporate partners filed Form IT-370-PF, had a short 2015 tax year, and were not able to e-file before the extended due date because the required forms were not available, then they have until June 27, 2016 to e-file its 2015 partnership return without penalty for late filing.
