The Oklahoma Tax Commission has published its 2019 Income Tax Withholding Tables, Packet OW-2. The new tables become effective January 1, 2019.
The only change is that employers with Oklahoma withholding/wage details must submit W-2 and W-3 for tax year 2019 by January 31, 2020. Previously, including tax year 2018 (due in 2019), the due date was February 28.
