CCH ProSystemfx does as many years as you want to file. The only ones you can paperfile are ones that BSA won't accept. I had one client who was a US citizen without an SSN but at the time of filing was no longer a US citizen. Because he WAS a US citizen, he had to have an SSN for that timeframe. Because he was no longer a US citizen, he could only apply for an ITIN. The proramme couldn't handle something so wierd so I sent paper ones for that guy. There were two for trusts that couldn't be processed since it was confused as to whether an EIN or SSN was required. All the rest were e-filed under the new system through CCH.
