Oklahomans now have until June 15, 2021 to pay their 2020 individual and business income taxes, and their first quarter 2021 estimated income tax payments. As a result of the recent disaster declaration issued by FEMA, the IRS announced the tax deadline extension for all individuals who reside or own a business in all of Oklahoma’s 77 counties to provide relief for those affected by February’s historic winter storms. Following the announcement from the IRS, the Oklahoma Tax Commission ordered the payment deadline extension to provide further relief to Oklahoma taxpayers. The Oklahoma Tax Commissioners elected to adjust the payment deadline extension from April 15 to June 15 for all individuals that reside or own a business in Oklahoma.

Due dates for other tax types, including sales and withholding, remain the same.
