You must pay estimated income tax if you are self employed or do not pay sufficient tax withholding. Estimated tax payments must be sent to the Oklahoma Department of Revenue on a quarterly basis. For more information about the Oklahoma Income Tax, see the Oklahoma Income Tax page.

Oklahoma may also allow you to e-file your Form OW-8-ES instead of mailing in a hard copy, which could result in your forms being received and processed faster. For more details, read more about the Oklahoma e-filing program.
