Common questions about BOX 12DD
Can I deduct Box 12DD?
No. It's purely informational — your share is already pre-tax (excluded from Box 1) via the payroll deduction.
Why is Box 12DD so high?
It includes your employer's contribution. Most employers pay 70–80% of the premium, so seeing $20,000+ for family coverage is normal.
