Getting Started in Glacier Tax Compliance

Last updated Tuesday, May 16, 2023

On This Page:


Glacier Tax Compliance is a secure, web-based application used by the UW to determine the correct taxation on wages for Foreign National employees. Only Foreign Nationals present in the US should submit information in Glacier Tax Compliance.

Information that a Foreign National must provide in Glacier Tax Compliance includes:

  • Visa start and end dates
  • Passport page with visa stamp
  • Country of residence
  • Country of citizenship
  • U.S. address
  • Foreign address
  • Social Security number or ITIN

Based on this information, the UW is then able to determine if the Foreign National:

  • Is eligible for any federal withholding tax exemptions via a tax treaty
  • Has passed a substantial presence test
  • Has become an alien resident for U.S. tax purposes
  • Is exempt from FICA taxes (Social Security/Medicare) based on USCIS NRA rules

Failure to complete Glacier Tax Compliance information and provide documents to the ISC Payroll Office may result in inaccurate tax withholding and/or loss of tax treaty exemptions.

Tax Treaties – Eligibility, Paperwork, and Renewal

A tax treaty is an agreement negotiated between the United States and a foreign country to reduce double taxation on residents of the foreign country. The information you provide in Glacier Tax Compliance will help the ISC determine if you are eligible for any tax treaties that will exempt you from having to pay federal withholding taxes.

  • Lists of current wage tax treaties and Scholarship/Fellowship tax treaties are available in IRS Publication 901. Carefully review the eligibility criteria specified, including in footnotes.
  • Refer to IRS Publication 519 for information regarding taxes for nonresident aliens.
  • Information on which countries have tax treaty agreements and the tax treaty details are available on the IRS website.

Generating your tax treaty eligibility paperwork
Glacier Tax Compliance generates the tax treaty-related paperwork that you need to include in your Glacier packet:

  • IRS Form 8233 Glacier Tax Compliance will generate Form 8233 and a Form 8233 attachment that is a verification of your tax treaty eligibility. Both forms must be signed and dated, if you have wage payments that have been determined to be exempt from federal withholding tax.
  • IRS Form W-8BEN – Glacier Tax Compliance will generate this form if you are determined to be eligible for a Scholarship/Fellowship tax treaty.

There are several requirements to be eligible for a tax treaty benefit for federal withholding taxes. If Glacier Tax Compliance determines that you are not eligible for a tax treaty, no tax treaty-related forms will be generated. However, you can still claim the exemption as part of the personal tax return you file with the IRS.

  • Tax treaty eligibility paperwork must be renewed.
    For your federal taxation to continue to be appropriately reduced:
    ⇒ IRS Form 8233 must be renewed every calendar year.
    ⇒ IRS Form W-8BEN must be renewed every three calendar years.

Every November, foreign nationals who might again qualify for a federal withholding tax exemption on their wages must renew their Form 8233 (and the required attachment) for the upcoming year and send that paperwork to the ISC for processing. Note that, to be eligible to renew your Form 8233, you must:

  • Have a social security number or ITIN entered in Glacier Tax Compliance, and
  • Be a nonresident alien for tax purposes at the beginning of the new calendar year, and
  • Have work authorization status that has not expired, or will not expire before the end of the current year.

Glacier will notify you via email when the renewal period has opened. The email you receive will provide you with step-by-step instructions for renewing your paperwork via Glacier Tax Compliance.

To ensure processing in time for your first paycheck in January, your paperwork must be:

  • printed single-sided, and
  • signed where indicated, including the Tax Summary Report Update cover page, and
  • received by ISC Payroll by the deadline indicated in the renewal email. Refer to step 9 of the Accessing Glacier Tax Compliance and Assembling Your “Glacier Packet” section above for the mailing address.

Frequently Asked Questions

Getting Help

Enter your information in Glacier Tax Compliance even if you don’t yet have an SSN or ITIN – refer to the step-by-step procedure in the “Accessing Glacier Tax Compliance and Assembling Your ‘Glacier Packet'” section, above.

If you are receiving payments through UW Payroll, you must apply for a Social Security Number (SSN) as soon as possible; if you are not able to receive an SSN, you must apply for an Individual Taxpayer Identification Number (ITIN):

Then, once you receive your SSN or ITIN, you must take the following actions to ensure the appropriate systems and records are updated:

  1. Contact your department’s HCM Initiate 2 to ask them to enter your SSN/ITIN in Workday.
  2. Log into Glacier Tax Compliance (see “Accessing and Using Glacier Tax Compliance,” below) and enter your SSN or ITIN. This will allow Glacier to recalculate your tax status and determine if you are eligible for a federal withholding tax exemption through any tax treaties. You will need to print, sign, and send an updated Glacier packet, including a copy of the SSN card or ITIN notice, to the ISC Payroll Office.
  3. Lastly, if you are a student, the UW Registrar’s Office will need your SSN/ITIN for tuition reporting purposes. Contact them at; DO NOT include your SSN in your email.

In Glacier Tax Compliance, select the “online help” icon in the lower right section of the screen.

You can also email Glacier Tax Compliance support at Note that it may take up to 2 business days to receive a response.

Please contact the ISC, using the subject “Glacier Tax Compliance help.”

First, you will need to update your information in Glacier Tax Compliance with the new work authorization information and send the new Glacier-generated paperwork to the ISC Payroll Office.

Next, contact your department’s I-9 Coordinator for assistance to update your Form I-9 in Workday. Refer to the Completing Form I-9 in Workday section of the Foreign Nationals Payment & Tax Information page for instructions.

If you are a student, please contact the UW International Student Services Office.

If you are academic personnel (faculty, research scholar, etc.), please contact the UW International Scholars Office.

Using Glacier Tax Compliance

Yes. All foreign nationals receiving payments through Workday must use Glacier Tax Compliance to verify the tax status and to track work authorization documents. The Glacier Tax Summary Report and the required documents are kept for IRS audit purposes.

No. Only foreign nationals present in the US should complete Glacier Tax Compliance. Foreign nationals with nonresident alien tax status, working outside the US will need to work with their department to complete the Certificate of Foreign Status and Department Confirmation letter. Instructions and links to the required forms can be found in the “Ensuring Correct Taxation If Working Outside the US” section of the Foreign Nationals Payment & Tax Information page.

Yes. DACA recipients are foreign nationals for immigration purposes. The citizenship status is not as a permanent resident or US citizen. The UW requires all foreign national employees working in the US to complete Glacier Tax Compliance. Contact the ISC if you need help completing Glacier Tax Compliance.

Note that Glacier Tax Compliance requires a foreign address. If a permanent foreign address is not available, DACA recipients should enter N/A in the street address line, and choose their city and country of origin.

If you have received the I-797C receipt from USCIS, contact the ISC to confirm that the extension applies to your work authorization. The ISC Payroll Tax and Accounting team will provide specific instructions on the dates to enter in Glacier Tax Compliance and the documents that must be sent to the ISC Payroll Office.

A list of work authorization documents eligible for a 180-day extension is available on the USCIS website.

No. The information in Glacier Tax Compliance is confidential and not shared with other agencies. Access to the information in Glacier Tax Compliance is only available to the UW department Glacier Administrator and the UW ISC Payroll Office.

No. The information in Glacier Tax Compliance should NOT be changed. This is the information that is on file while you were working at the UW. Any changes to the information in Glacier Tax Compliance will result in changing the status of your Glacier account and a new Glacier paperwork will have to be sent to the ISC Payroll Office.

Tax Treaties

The UW follows the guidelines set by Glacier. The ISC applies any tax treaty-based federal withholding tax exemptions to foreign nationals’ paychecks as a courtesy. Even if Glacier doesn’t indicate an exemption, you can still claim the exemption when you file your personal tax return with the IRS.

No. Only paper version of the tax treaty forms with your original handwritten signature are accepted; paperwork cannot be sent as an email attachment or uploaded to a file sharing service for retrieval.

Please mail your paperwork to the ISC as soon as possible – refer to step 9 of the Accessing Glacier Tax Compliance and Assembling Your “Glacier Packet” section above for the mailing address.

Your exemption will be applied to your paycheck for the pay period after your forms have been received and reviewed.

The notice you received is about renewing your tax treaty exemption for next year. The Form 8233 and 8233 attachment must be renewed each year.

If you want to apply the tax treaty exemption for your pay in 2023, log into Glacier Tax Compliance, and select “Complete My Information for Tax Treaty.” Print the forms as single-sided (one per page) and sign, and date all forms with your handwritten signature. Send the signed tax treaty forms to ISC Payroll by the deadline listed in the notification.

Review your record in Glacier Tax Compliance as well as the information in the Tax Treaties – Eligibility, Paperwork, and Renewal section above.

If you still have questions, contact the ISC with the subject line “Tax Treaty Renewal.”

No. The Form W-9 is issued to resident aliens for tax purposes if there is an agreement between the US and their home country. Your W-9 does not need to be renewed each year.


Glacier Tax Compliance will determine your tax status. The Tax Summary Report will show the tax status in the section titled Tax Residency Status.

Note: Being a resident alien for tax purposes does not change your immigration status. Non-US citizens/permanent residents are foreign nationals regardless of tax status.

Social Security and Medicare taxes, also called FICA tax exemptions, are determined by Glacier Tax Compliance based on the tax status as a nonresident alien or resident alien for tax purposes.

For questions regarding FICA tax deductions, contact the ISC.

The UW does not refund federal withholding taxes deducted before the tax treaty forms are received. However, you can claim the federal withholding tax exemption when you file your personal tax return with the IRS. Any refunds will be issued to you by the IRS.

FICA tax (Social Security and Medicare) refunds are determined after the Glacier Tax Compliance paperwork has been received in the ISC Payroll Office.

If you are a foreign national (not a U.S. citizen/permanent resident), you are considered a nonresident alien for tax purposes unless you meet the substantial presence test for the calendar year (January 1-December 31). The tax status is determined based on time spent in the US and visa type. Additional information is available on the IRS website.

Information For Administrators


Departments that enter Foreign National employees (staff, faculty, students) into Workday should designate a Glacier Administrator. The Glacier Administrator is responsible for:

  • Adding new Foreign National employees* to Glacier Tax Compliance
  • Monitoring whether a Foreign National employee has submitted their required information to ISC Payroll

*Foreign Nationals that will not be receiving payments through Workday (i.e. Contingent Workers, Unpaid Academics, individuals with 100% PDR compensation) do not need to complete Glacier Tax Compliance.

Obtaining Administrator Access to Glacier Tax Compliance

Due to the sensitive information in Glacier Tax Compliance, ISC Payroll provides access to one Administrator per department; exceptions are made on a case-by-case basis.

Training is required before administrator access will be provided. To arrange a 30-45 minute training session, contact the ISC with the subject “Glacier Admin Training Request.” Please include your unit/department name, and whether you will be replacing your unit’s current Glacier Tax Compliance Administrator.

Using Glacier Tax Compliance

After completing the required training, Glacier Administrators can refer to the Glacier Tax Compliance Guide for Administrators for step-by-step instructions on adding employees and determining the status of their Glacier paperwork.

Glacier Tax Compliance is not the same as Glacier Tax Prep. The latter is used for filing tax returns.

US naturalized citizens and permanent residents should NOT complete Glacier Tax Compliance.

If your residency status has changed to U.S. Citizen or Permanent resident, please:

  1. Complete a new Form I-9 in Workday to update your immigration status.
  2. Contact the ISC so we can update your citizenship status in Workday.

As a reminder, the ISC cannot provide tax advice.
