The deadline for filing state taxes in Tennessee typically aligns with the federal tax filing deadline, which is generally April 15th. However, if this date falls on a weekend or a holiday, it may shift to the following business day. Tennessee does not impose a personal income tax, but it does have other taxes, such as the sales tax and franchise and excise taxes for businesses. It is important for taxpayers to check for any updates or specific changes to deadlines that may occur in any given year. For precise information regarding deadlines and requirements, it is advisable to refer to the current web page of the Tennessee Department of Revenue, which provides updated details and guidance.
