After filing I received a corrected employer W2 box 12W

[df6512]

After filing 2022 taxes, my employer sent a corrected W2 in July. Stating box 12W/HSA contributions have been corrected. The original reported amount was 4,400, the corrected amount is 4,000.  The bottom line does not change although the corrected amount is lesser.  Do I need to submit an addendum? Thank you

12a is not the proper box to report HSA contributions. The are supposed to be reported in box 12w.  

IRS instructions for 12

A—Uncollected social security or RRTA tax on tips. Include this tax on Form 1040 or 1040-SR. See the Form 1040 instructions.

W—Employer contributions (including amounts the employee elected to contribute using a section 125 (cafeteria) plan) to your health savings account. Report on Form 8889.

are you sure it's not 12w. if was supposes to be, your employer is probably not preparing w-2's correctly. 

we can do nothing. contact your employer to get this matter resolved.

Thanks.  It is in box 12a, but it is noted as W in front.  To answer correctly, it is 12W

Huh?  Don't get confused here. 

The use of the term "12a" is just a way to indicate the first line of box 12.

My W-2 forms had multiple boxes, actually labeled 12a, 12b, 12c, 12d,   but mine only used box 12a with a code D after it, and a $$ amount......since I only have $$ sent to a 401k, and the other 12b,c,d boxes empty.

Like, a person could easily have had three lines in box 12 with the following....IN ANY ORDER:

Box    Code    Amount         (my note as to what for)

12a     D           3000                (401k Contrib)

12b    AA          2000               (Roth 401k Contrib)

12c     W          4000                 (HSA $$ )

12d

_________

So the HSA contribution could be in any of those boxes, depending on how many contributions need to be noted.

One could say they have a box 12 with a code W and a $$ amount

........or just say they have a box 12a with a code W and a $$ amount

.....essentially.....same thing...so don't get hung up on the 12a, 12b, 12c.

The only problem a few folks have, is seeing the box labeled 12a, and thinking the "code' is an A.

_______

Now, in the TTX software, TTX doesn't bother labelling the multiple boxes as 12a, 12b, etc.....just lets you enter as many separate lines for box 12 as you need for any codes and $$ you actually have on your W-2

I am sure the OP meant is was on the W-2 box 12a  CODE W and not a code A.
