Tax Exempt Letters
The exemption letters and the University’s tax exemption number may be used only for authorized University business purposes. Personal or other unauthorized use of the tax exemption number or letter by any person may constitute a crime under 35 ILCS 120/13 and may result in disciplinary or legal action.
To obtain a tax letter, you will need to provide your SIU email address and possibly your Network ID (Dawgtag) and password to authenticate at the link below. For additional help, see the instructions.
