The day after the Oklahoma Tax Commission followed the previous guidance issued by the Internal Revenue Service to allow taxpayers to defer income tax payments but not filing requirements, U.S. Treasury Secretary Steven Mnuchin announced on Twitter that the IRS will extend the individual tax filing deadline until July 15, 2020.

Oklahoma statutes provide that individual income tax returns based on the calendar year are due on April 15 (returns filed electronically have until April 20). Provided, if the Internal Revenue Code provides for a later due date for returns of individuals, the statutes direct the Tax Commission to accept returns filed by individuals by later date set by the IRS and such returns shall be considered as timely filed. With the latest announcement from the Treasury Secretary, the due date for Oklahoma individual income tax returns is July 15, 2020.

Corporate and partnership income tax returns based on the calendar year are due 30 days after the due date established under the Internal Revenue Code. If the IRS does not extend the due dates for corporations and partnerships, those returns will still be due on May 15, 2020.
