If you live in the state of Tennessee, the Hall Tax is due April 17, 2018. Turbotax incorrectly states it was due April 15, 2018. I received the following from the TN Dept of Revenue. Please note the link to the PDF file.
“The Due Date for Calendar Year 2017 Tax Returns Is April 17, 2018 Rather Than April 15, 2018 Due dates for certain Tennessee franchise and excise tax returns, business tax returns and Hall income tax returns will be April 17, 2018, to be consistent with the Internal Revenue Service (“IRS”) federal income tax filing deadline.”
On a side note. There is no facility that I know of to quickly contact Intuit to inform them of their mistake. Unfortunately, I believe many will overpay their taxes in TN because Turbotax has the due date wrong in their software. People will pay an additional 5% tax penalty that they do not owe.
