What GLACIER is

GLACIER is an online tax compliance system for institutions that host or pay foreign nationals. It helps determine tax residency and treaty eligibility, manage paperwork, and prepare IRS reporting. The system calculates the substantial presence test, reviews applicable income tax treaties for possible exemptions, and prepares relevant withholding and treaty forms, plus year-end Forms 1042 and 1042-S for paper or electronic submission. Federal e-filing is supported, and recipient delivery is available both ways. Administrators can invite foreign nationals to enter information directly; GLACIER tracks missing details and sends email reminders. Standard and ad-hoc reports can cover treaty exemption dates, residency changes, missing SSNs or ITINs, and immigration status expirations. The maker describes it for universities, colleges, research institutes, hospitals, foundations, exchange organizations, and government agencies. It runs in a current web browser and needs internet access and a printer, with no client installation. Arctic says it uses TLS, database encryption, firewalls, daily backups, and weekly offsite backup rotation. Pricing is available on request; plans are billed annually on a calendar-year basis, with a one-time setup fee and annual tax training also applying. A free trial is offered, with no duration stated.
