Summary: written with AI from the case record.
What it's about
The Supreme Court upheld the Treasury Department’s rule treating residents as full-time employees who do not qualify for that exemption, agreeing with the Eighth Circuit.
The dispute turned on whether the federal payroll-tax law’s student exemption covered medical residents.
Question presented
Can the Treasury Department categorically exclude all medical residents who meet the FICA definition of student and who would be subject to the FICA student exemption?
What the Court decided
Holding
The Treasury Department’s full-time employee rule is a reasonable construction of §3121(b)(10). 568 F. 3d 675, affirmed.
- Result
- Affirmed
The Court's reasoning
The Court concluded that Treasury’s rule was a reasonable reading of the federal tax law’s student exemption. The rule treats medical residents as full-time employees, so they do not qualify for that exemption.
The vote
- Majority author
- John G. Roberts, Jr.
What's next
The Eighth Circuit’s ruling remains in place, and Mayo Foundation and the University of Minnesota’s refund claims do not succeed under that ruling.
