Tennessee Filing Due Date: Tennessee’s individual income tax applies to individuals who receive interest (from bonds and notes) and dividends (from stock). TN individual income tax returns are due by April 15, in most years — or by the 15^th day of the 4^th month following the end of the taxable year (for fiscal year filers).

Extended Deadline with Tennessee Tax Extension: Tennessee offers a 6-month extension, which moves the individual filing deadline from April 15 to October 15 (for calendar year filers).

Tennessee Tax Extension Form: To request a Tennessee extension, file Form INC-251 by the original due date of your return. Form INC-251 can be completed and mailed, or file electronically using Tennessee’s Online Services: apps.tn.gov/etax

Tennessee Extension Payment Requirement: A tax extension gives you extra time to file. It does not give you more time to pay your Tennessee income tax. All state tax payments are due by the original deadline of the return. Any TN tax that hasn’t been paid by the proper due date will be subject to interest and penalties. You can make a Tennessee extension payment with Form INC-251, or pay electronically through TN Online Services: apps.tn.gov/etax
