Employee & Dependent Education Assistance Taxation

Ohio State employees who take advantage of tuition benefits provided by the university (either for themselves or dependents) should be aware of the tax consequences.

This page provides a summary of IRS regulations related to tuition benefits so that you can plan ahead.

Employee benefit- Based on IRS regulations, you should expect to be taxed on any graduate tuition benefit that exceeds $5,250 in a calendar year. (This also means that the first $5,250 in tuition assistance that the university provides to faculty and staff each calendar year for graduate-level courses is not subject to taxation.)

We recommend that you prepare ahead of time for the tax consequences of your academic coursework. The university cannot provide tax advice to individual employees, so we would encourage you to discuss your particular circumstances with a tax professional.

Dependent benefit- Please note that tuition assistance for dependents, including spouse, same sex domestic partner, or dependent children, who are taking graduate-level courses, is subject to taxation. Dependent undergraduate tuition assistance is taxable to the employee if the dependent is not eligible to be claimed on the employee’s federal tax return for that calendar year. (See questions on the Application for Dependent Tuition Assistance on the Office of Human Resources website).

Additional tax for the tuition assistance benefit is based on the employee's current W-4 on record at the time of taxation. The W-4 can be accessed through Employee Self Service, under Time and Pay, W-4 tax Information.

Biweekly paid employees are taxed over six pay periods for the Spring and Autumn semesters and four pay periods for the Summer semester.

Monthly paid employees are taxed over three pay periods for the Spring and Autumn semesters and two pay periods for the Summer semester.

The months to be taxed for Spring semester: March, April, and May; for Summer semester: August and September; and for Autumn semester: October, November, and December. This timeframe may vary slightly depending upon payroll processing dates. An email notice is sent to employees prior to the first pay to be taxed, stating the specific pay periods and the additional taxable income benefit on which they will be taxed.

Paycheck Modeler, located in Employee Self Service under Other Payroll Information, may be used to estimate a net check by adding the tuition assistance taxable amount per pay to the Earnings step, then continuing through the Deductions and Taxes steps to calculate a net pay check. The Taxes step will also allow hypothetical changes to the W-4 exemptions and recalculate the check using the changed information. To request W-4 exemption changes within the payroll system, please use the W-4 Tax Information page in Employee Self Service.

How much additional tax is withheld depends on:

  • What your W-4 marital status and exemptions are in the payroll system, which can be updated at any time during the year;
  •  Your salary; and
  •  Your education assistance taxable income for the pay period; which may put you into a higher tax bracket for the pay periods that are taxed


Example #1: Check stub for a Monthly paid employee without current Education Assistance in the pay. There is a year-to-date amount from a previous semester where the employee has exceeded the $5,250.00 exempt limit. Gross pay is $6,353.00 and net is $3,963.79.

Example #2: Check stub for the same Monthly employee with Education Assistance taxable income of $4,783.50 added. The gross pay is still $6,353.00, and the net is $2,323.23. The difference in the two net pays is the additional taxes on the education assistance. (This is for summer semester when the employee is taxed over 2 pay periods).

Form W-2 / Year End

Ohio State is required to furnish all employees with a Form W-2 showing their compensation and tax withholding amounts for the calendar year by January 31 of the following year. You will use the W-2 to complete your yearly tax return by April 15.

University employees may choose to access their W-2 statement electronically through Employee Self Service (preferred) or to receive a paper copy mailed to their home address on file.

The benefits of receiving an online W-2 form are:

  • Faster access than through the mail
  • Significantly less risk that your W-2 may be lost or stolen, compared with mailed delivery
  • Available on demand from any location with internet availability
  • Environmental impact

Employers must comply with specific Internal Revenue Service (IRS) regulations (26 CFR 31.6051-1) to issue electronic W-2s, and employees must provide their consent to receive an electronic W-2 instead of a paper copy. 

How to access your W-2 electronically

To access your W-2 online for 2013 and onward, you must provide your consent through Employee Self Service. There is a W-2 Consent section with a Consent Now button. Alternatively you can look for the Tax Information folder under the Time and Pay section and click on the W-2/W-2c Consent link.

Once you have signed up for electronic forms, you can print copies of your W-2s for tax years 2013 and onward at any time. To access our forms, log on to Employee Self Service and under the Tax Information folder in the Time and Pay section, click on the View W-2/W-2c Forms link. The most recent tax year forms will display. To view your tax forms for a different year, click on the View a Different Tax Year link.

Disclosure Statement

  • Scope and Duration of Consent: An employee’s consent to receive a W-2 form in electronic format is effective only for all future tax years until consent is withdrawn. Payroll Services will notify employees each year when the W-2 Forms are available for access online.
  • Procedure for Obtaining Paper W-2s After Consent Given: After giving consent, an employee may still request a paper Form W-2 by contacting Payroll Services in writing (either by email to or by U.S. mail to (901 Woody Hayes Dr., Blankenship Hall, 2nd Floor, Columbus Ohio 43210). The request for a paper Form W-2 will not terminate consent to receive W-2 Forms electronically in the future.
  • Withdrawal of Consent: An employee may withdraw his or her consent at any time. Consent withdrawn by employees is only effective for W-2s not yet issued, and does not apply to previously issued Forms W-2. To withdraw your consent, you may change your selection in Employee Self Service to receive a paper copy or send a request to
  • Terminated Employees: All terminated employees regardless of consent will no longer be able to access the electronic W-2. A paper W-2 will be sent to all terminated employees. Terminated employees can contact Payroll Services at (614) 292-2311 for instructions on updating personal information.
  • Updating Information for Active Employees: It is the employee’s responsibility to notify Payroll Services of any changes to personal information such as social security number or name by submitting a Change of Record form. Address changes must be made via Employee Self Service. It is Payroll Services responsibility to notify employees of changes to the University’s contact information.
  • Hardware and Software Requirements: The hardware and software requirements needed to access, print and retain Form W-2 electronically include an internet connection, web browser, and Adobe Acrobat Reader.
  • Inaccessible W-2s or Technical Problems: If an employee consents to accessing an electronic W-2 and is unable to access their form online due to a technical problem, incorrect login or password, or incorrect e-mail address, the employee may request a paper copy.

Form W-4: Employee's Withholding Allowance Certificate

All Ohio State employees are required to complete a Form W-4 when they are hired. You will also need to review your Form W-4 and make appropriate changes if you have had a major life change, such as marriage or divorce, death of a spouse, or birth/adoption of a child.

  • To complete or make changes to your Form W-4, log into Employee Self Service, select the W-4 Tax Data option, and follow the instructions on the screen.
  • For more information, see Withholding: About Your W-4 below or try the IRS Withholding Calculator.

Withholding: About Your W-4

Withholding is the amount of taxes that are taken from your paycheck based on factors such as whether or not you are married, have children, or have multiple jobs. It makes sense to take a few minutes to make sure that what is being withheld from your paycheck matches your actual tax liability. If you're having too much tax withheld, that's money you can't use until you get your refund. If you're not having enough withheld, you will owe tax at the end of the year, and you may even have to pay a penalty. Generally, a penalty will apply if your withholding and estimated tax payments total less than 90 percent of your current year's tax liability and less than 100 percent of the previous year's tax.

Reasons to Recheck Your W-4

You should pay particular attention to your withholding if you received a big refund check this year or if you had to make a tax payment that was more than you could comfortably pay. Also check your withholding if you had a significant change in your life this year, like marriage, divorce, birth or adoption of a child, purchase or sale of a home, or retirement. There is a good chance you're not having enough withheld if you have more than one job, if your spouse works, if you have income not subject to withholding, such as rent, dividends, interest or capital gains, or if you owe other taxes like self-employment or household employment taxes.

How to Find Out if You Are Withholding Enough

Need help in figuring out whether you are withholding enough? You can review How Do I Adjust My Tax Withholding? (IRS Publication 919). You can also use the IRS Withholding Calculator. With the help of current pay stubs and a copy of last year's tax form, you can check to see if you are withholding the right amount, then use the calculator results to change your W-4 tax data through Employee Self Service.

How to Adjust the Amount of Withholding

You can adjust the amount being withheld from your paycheck by changing your W-4 tax data through Employee Self Service.
