Taxpayers filing a CBT-100, BFC-1, or CBT-100S, with an original due date of November 15, 2018, December 15, 2018, or January 2019, (i.e. fiscal tax year filers which had a tax year ending July 31, 2018, August 31, 2018, September 30, 2018, respectively) were granted an automatic extension to file their tax returns by February 15, 2019. We will not charge late filing penalties or interest if the returns were filed by the extended due date. The extension applies only to the filing of the return. It did not extend the time to make all required payments.
