Would 12b DD of $8004.10 be considered additional contributions?

[MichelleT · Accepted solution]

No. 

W-2 box 12 code DD :  this has no effect on your tax return.

DD—Cost of employer-sponsored health coverage. The amount reported with Code DD is not taxable.

Code DD in Box 12 is the cost that your employer/and/or you, paid for your Health Insurance.

It is informational but it is not included in your tax filing.  You can enter it in the W-2 Box 12 drop down menu - it is found after z.
