Thank you for this insight. What if the amount that our employer entered in box 12, code W is $1000 higher than the amount they subtracted from our Gross Pay in the W2 worksheet on the right side of the W2? Might this be because the employer also contributed $1000 to our HSA that year--would that total number be included in box 12? Or is the discrepancy an error? (The higher number, from Box 12, is the same as the number of "Total Contributions" shown on our 5498-SA.)
