Should I ask my employer to revise a W2 or should I consult a tax advisor

[breychak-1]

My employer incorrectly had my status as exempt, I asked them to revise last year and they did not and only have prompted me to consult a tax advisor rather than fix my record. Now I owe ridiculous taxes due to their reporting errors I tried to correct.

They can't revise your W-2 unless shows amounts that are different than what was actually withheld  Based on your questions, it is not the problem.  The problem is they did not withhold income tax.  If you submitted a Form W-4 with something other than "exempt", then you should be able to have the penalties waived. You won't however, be able to reduce the amount of tax you owe.  The total tax on your 2021 income is not determined by your withholding status or the amount withheld.  It's based on your income.  Even if your employer was not withholding enough tax, it is your responsibility to submit a new W-4, and/or pay estimated tax.  Consulting a local tax professional would not be a bad idea.
