If I use Turbo Tax to prepare my taxes with locally installed software, and specifically Turbo Tax with New York State, to prepare my returns, am I permitted to file my returns by mail and paper, or does state law require e-filing?
From New York State: E-file requirement for individual taxpayers
Who must e-file
You're required to electronically file your return if you meet all three of the following conditions:
- you use software to prepare your own personal income tax return; and
- your software supports the electronic filing of your return; and
- you have broadband Internet access.
So if using TurboTax to prepare software, than you must at least efile through the tax software. And from answer links above, efiling will require certain information being stored by Intuit.
