The Oklahoma Report of Compensation Paid (Form W-2) is an annual report that employers in Oklahoma are required to send to their employees and to the Oklahoma Tax Commission. It is used to report wages, bonuses, tips, other compensation, and taxes that were deducted from the employee's wages during the course of the year. The report is used to determine the amount of Oklahoma taxes that must be paid by the employee. There are two types of Oklahoma Report of Compensation Paid. The first type is a Wage and Tax Statement, which is used to report wages paid to an employee and the taxes withheld from those wages. The second type is an Employee's Withholding Allowance Certificate, which is used to show the number of withholding allowances that an employee claimed on their tax return. Both of these reports must be filed with the Oklahoma Tax Commission before the April 15th filing deadline.
