Employers in Oklahoma must conform with these state rules relating to income tax withholding and administration.
General Withholding Requirement: Oklahoma income tax generally must be withheld from wages paid to resident employees for services performed either within or without the state and from wages paid to nonresident employees for services performed in the state. However, a resident employee's wages are not subject to withholding if the wages are earned in another state that requires withholding.
Employee Withholding Exemption Forms: Oklahoma does not have a state withholding exemption certificate. However, Federal Form W-4, which must be completed by each employee to determine the appropriate level of federal income tax to withhold from earnings, also should be used for state withholding purposes.
Reciprocal Agreements: None.
