Oregon automatically grants a filing (not payment) extension to October 16, 2023 if you filed an approved federal extension and don't owe. However, if you do owe, print and mail Form 40-EXT by April 18, 2023 along with a check to avoid penalties and interest. See this TurboTax Help Article for more information.
