Summary

  • Ohio employers must withhold state income tax from the pay of employees who are Ohio residents. For employees who are Ohio residents but work in another state, the employer must withhold for the other state's taxes, unless the other state does not require withholding. Withholding is required on work performed by a nonresident within Ohio, unless a reciprocal agreement is in effect with the nonresident's state of residence or the nonresident is considered a short-term business traveler. Ohio has reciprocal agreements with Indiana, Kentucky, Michigan, Pennsylvania and West Virginia. Expatriates are subject to withholding on foreign earned income. See Withholding on Residents, Nonresidents and Expatriates.
  • Form IT-4 is used by employers to determine the number of exemptions that employees are entitled to claim and how much Ohio income tax to withhold from employees' pay. See Employee's Withholding Allowance Certificate.
  • Employers must withhold on supplemental wages at a flat rate of at least 3.5 percent.See Supplemental Wages.
