How do I change my tax withholding?

Tax is withheld in accordance to the tax status you claim on your W-4 form. An employee may change the exemptions they claim on their W-4 form at any time and as often as they want. The W-4 form may be completed online but must be printed, signed and then sent to the Payroll office (AQU 202). It may also be scanned and emailed.

Please note that empoyees may need to complete a Federal and MN W-4 depending on what is being claimed.

What should I claim on my form W-4 Employee's Withholding Allowance Certificate?

The number of exemptions you claim on your W-4 form is different for each individual. The Payroll Department cannot advise you of what you should claim on your W-4 form, only your tax accountant can do that. The W-4 form has a worksheet attached to it to help people calculate what they should claim on their W-4 form. If you need any assistance in completing the W-4 form please contact the Payroll Department via email at

When are the W-2 annual statements sent?

W-2 tax statements are mailed once a year to the employee’s home address by no later than January 31st of the following year. You can also access a copy of your W-2 via Murphy Online at approximately the same time.

What do I do when my citizen status or Visa type change?

When an international employee becomes a citizen they must notify Human Resources and Payroll immediately.  A new W-4 form needs to be processed for Payroll and the I9 form needs to be updated for Human Resources.

When an international employee changes their VISA type, they should notify Payroll.  This may or may not affect their tax status but it is always best to confirm this with the Payroll Department.

How do I update my W-2 mailing address?

If you have moved, it is important that you update your address in Murphy Online.  The deadline to update addresses to reflect where your W-2’s will be mailed is the second Friday in January.  If you do not update your address by the second Friday in January, your W-2 will be mailed to the incorrect address.  It is your responsibility to make sure your addresses are up to date in Murphy Online.
