Tax Withholdings and Forms

If you identify any errors in your withholding, please contact the Cornell Payroll Office at (607) 255-5194 for assistance. If you have any general federal or state withholding tax questions, or if you are living or working in a state other than New York and would like to discuss state tax withholding based on your individual circumstances, you should consult your personal tax adviser.

Federal and New York State Withholding Allowance Forms

Employees can use make changes to their federal and state withholding allowances using Workday.

Employees are responsible to ensure that any applicable additional local income taxes are withheld. If the correct taxes are not being withheld, you might have unexpected personal income tax liabilities at year-end or be required to file a tax return in additional states to request a refund of tax that was withheld by Cornell.

If you need assistance beyond the provided instructions, contact your unit's payroll representative or University Payroll at 377 Pine Tree Road (behind the East Hill P&C), or call (607) 255-5194.

Out-of-State Employees and Nonresident Aliens

If you are an out-of state (non-NY resident) employee or a nonresident alien, you are not eligible to use Workday to update your withholdings and must submit paper forms to Payroll, either in person or by mail.

If you have any questions, contact Payroll at (607) 255-5194 or


Keeping Your Workday Addresses Current

Employees: Please review your Workday home and work addresses and ensure that they are current and correct; the Payroll office uses both of these addresses to determine what state and local income tax is required to be withheld.
If you find that either address is incorrect, please update this field in Workday. If you have any trouble updating your home or work address in Workday, please reference the support materials available on the Employee Self Service page, or contact the HRIS Helpdesk at

Students: All address changes must be done through Student Center. Remember that it's your responsibility to ensure, on an ongoing basis, that your home and work addresses in Workday or Student Center are current and correct. Failing to update your addresses can cause income tax to be withheld in the wrong states or local jurisdictions.


Federal and State Tax Allowances

If your marital status or withholding allowances have changed, or will change for the next tax year, the IRS recommends that you submit a new Form W-4. You can update your withholding forms in Workday.

Social Security Wage Base

The 2015 Social Security taxable wage base has increased to $118,500. The tax rate is 6.2% and, therefore, the total tax withheld for employees that meet or exceed the wage base is $7,347.


Medicare Tax and Additional Medicare Tax

The Medicare tax rate remains 1.45%. Additional Medicare tax applies to taxable Medicare wages of $200,000 or more; the tax rate is 0.9%. There is no maximum cap on taxable Medicare wages.


Local Taxes

If you reside in New York City or Yonkers, your earnings are subject to local income tax. If local taxes are not currently being withheld from your check, please complete an IT-2104 Employee’s Withholding Allowance Certificate.

For instructions, see How to Update Your Federal and State Withholding Allowances (PDF, 636 KB).

Note: Workday does not automatically set up resident taxes based on the residence address; this must be done manually by the employee. Payroll cannot collect local withholding taxes based on Workday alone.
