Q. I have a code DD deduction on my W-2. What does this mean?
A. Code DD includes cost of employer-sponsored health coverage. Information only.
Q. Where do I report it?
A. You enter your W-2 exactly as received (code DD and the amount in box 12). TurboTax will automatically report it, as needed. In the case of code DD, it's only informational and nothing about it is entered on the tax forms. Employer paid health insurance is a tax free benefit.
