That's actually okay, and you can still easily file your tax return without one. Not all W-2s have Control Numbers associated with them, or printed on them. Please allow us to explain.
Form W-2 (wage statement) Box D
is a Control Number field. It is usually located below the Employer's Name and
Address.
The Box D Control Number is a code
that identifies your unique Form W-2 document in your employer's records.
This number is assigned by the company's payroll processing software, and is
needed if attempting to electronically import your W-2 into a tax software
program (like TurboTax). Please note that not all W-2s (or employers)
will necessarily include a Box D number. Your alternative to importing a
W-2 document is to simply input the same information manually.
The actual Control Number
itself is basically irrelevant to completing your tax return, unless you
wish to import your W-2 into TurboTax; 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. In fact,
you should be able to 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. I've linked this answer to that FAQ page below.
I hope this information is useful to
your needs. Thanks for asking this question.
