Box 12-W — Code W — Employer HSA contributions
Employer contributions to your Health Savings Account, including amounts you contributed via payroll if shown here under employer reporting rules.
What it means
Code W totals generally count toward the annual HSA contribution limit. Employer contributions are excluded from income when properly reported; your own outside contributions may still be deductible on Form 8889. Coordinate Code W with any personal deposits so you do not overfund.
