The answer to your question is that you will not be able to electronically import your W-2 statement without a Control ID Number. That is not necessarily a TurboTax program limitation, as it will apply to all competing tax preparation software packages as well.
When present, the Box D Control Number is usually located below or near
the Employer's Name and Address. It is a
code that uniquely identifies your W-2 document in your
employer's records. This number is assigned by a company's payroll
processing software, and is needed if attempting to electronically
import your W-2 into a tax software program (like TurboTax).
Your alternative to importing a W-2
document is to simply input the same information manually.
The
actual Control Number itself is not necessary in completing your tax
return, unless you wish to import your W-2 into TurboTax (or other tax
software); and it that one instance it is required. In other words, the
W-2 Control Number, whatever it is, will never increase or decrease
your actual tax refund (or your amount owed) by a single penny.
If
you type in your W-2 manually, rather than importing it
electronically, then you should not have to enter anything from Box D at
all, if you do not want to. In fact, you can simply leave the field
blank. The exceptions to that would be if you are attempting to e-file
your return and see some sort of W-2 Control Number related error; or if
the program insists on a value before allowing you to continue. In
those cases, we have a TurboTax FAQ article that can help you resolve any such problems. We've linked
this answer to that FAQ page below.
We hope this information is useful to your needs. Thanks for asking this important question.
