I held 2 jobs in 2023.
Job1 a small business I started in 2022, quit in summer 2023.
Job2 a large business I started in early 2023, still working there.
When I was entering my W2 numbers of the 2 jobs. I entered numbers from
job2 first, and it showed that my federal/state return would be
$1700/$1400 respectively. When I then entered numbers from job1, the
return amounts drop to $200/$800 for fed/state, a $1500 and $600 drop
respectively, meaning I owe the government $2100.
I went to job1's office and asked to see the original papers I filled
out. Turns out on the W4, in section 3 claim dependent, since I do have
an adult dependent, I entered 500 per the instruction "multiply the
number of other dependent by $500"; On the W4 for the state, I entered 1
each on line A-no one can claim me as dependent, line B-single and only
1 job (when I signed up for job1 in 2022 I only had that one job), line
D-number of dependent I will claim on my tax return, and line E- filing
as head of household.
Everything was filled out truthfully.
I cross checked my numbers on the 2023 W2 with an ex-coworker at job1,
who worked just for 4 months in 2023. He grossed $10000 and had $900 for
federal withhold. Alas, my gross was $22000 and I had just $950 for
federal withhold. I can see here I was under-withheld for federal and I
can understand if I owed the government $1000ish in tax money, but $2100
is substantial.
BTW, since I started job1 in 2022, my 2022 return was also ~$1500 short
as soon as I entered the W2 numbers from job1. (I held a few other
short-terms jobs in 2022 subsequently)
Job1 uses Quickbook for payroll, and upon my inquiry about the original
papers the manager showed me in the software where they put down $500
following what I had put down on the W4. I don't remember what the
screen says specifically, just the $500 number.
My intuition on this is unfortunately heavily influenced by the extreme
negative working experience at job1 which was why I quit, but I have
also brought the issue to a pro-bono tax professional in town here, who
acknowledges that they didn't withhold enough, but opined that there is
probably no wrongdoing or fraud on the employer's part.
I have not filed my 2023 tax return just yet.
Any advice or opinions?
