Form IT-4 and W-4 Explained
Purpose of these forms
The purpose of the W-4 and IT-4 is to determine the amount of tax that will be withheld from your paycheck for the IRS and State of Ohio respectively.
- The W-4 (Federal)
- The W-4 is the Employee’s Withholding Allowance Certificate. It determines the amount of taxes withheld from your paycheck for federal taxes. More information can be found on the IRS website at: http://www.irs.gov/
- The IT-4 (State)
- The IT-4 is the Ohio Employee’s Withholding Exemption Certificate and determines the number of exemptions you will claim. The more exemptions you claim, the less taxes will be withheld from your paycheck.
- The IT-4 allows you to claim exemptions for yourself, your spouse, and any dependents. The number of exemptions claimed does not determine how much you may or may not owe when you file, it only determines how much is withheld from your paycheck for you.
- You are only allowed to claim up to the number of exemptions you are entitled to. In other words, if you are only eligible for 1 exemption, you can claim 1 or 0 exemptions, but not 2 or more.
- For the IT-4, if your employer agrees, you may be eligible to have additional taxes withheld from your paycheck. Taxes will be withheld based on the number of exemptions and, if approved, the additional amount you have listed for each pay period.
- The IT-4 also asks for your school district name and number so that taxes can be withheld from your paycheck for school district income taxes. All Ohio employers are required to withhold school district income taxes if the district you listed on your IT-4 is a taxing school district.
How do I obtain these forms?
The IT-4 can be located on the Ohio Department of Taxation's website at: http://tax.ohio.gov and the W-4 can be located on the Internal Revenue Service’s website at www.irs.gov

School District Withholding Information
Many school districts in Ohio have an income tax.
- School district income tax is based on where you live, not where you work. If you live in a taxing school district, you are required to file and pay school district income taxes.
- On the IT-4, there is a place to list the school district name and 4 digit school district number.
- If you are unsure if you live in a taxing school district, you can use The Finder on the Ohio Department of Taxation’s website. The Finder allows you to input your address to see if you live in a taxing school district. Your result will show the school district name, 4 digit number, and tax rate.
