Can an employee increase the amount of Ohio tax withholding?

If an employee expects to owe more Ohio tax than will be covered through normal withholding, the employee can elect to have additional withholding deducted by claiming fewer exemptions on the Ohio IT 4 or by requesting a specific additional amount of tax be withheld each pay period by indicating the additional amount on the Ohio IT 4.
