<prompt> Human: We just received our W-2s and I started our taxes, and to my complete and total surprise, we owe along the lines of 3K this year. We have 2 kids, mortgage, student loans...all the good deduction stuff. We both claim 2 dependents on our W-2 for Federal. After a bit of crunching, I found that my wifes quarterly bonuses about 15 of her total income were not taxed properly. They took out the FICA and Medicare but not FED. It turns out the book keeper at her work treats them as one-time quarterly bonuses and wasnt taxing at her regular salary rate. So essentially 10k went untaxed. The question: Other than grin and bear it, what can we do? She took it to accounting and they recognize their mistake and will correct going forward. It just seems like we shouldnt get punished for it. I already know my wife should look at her paystubs. Her company has made it fairly obnoxious to acquire them with some website that is always breaking down. Edit Sorry: I wasnt asking if I had to pay my taxes. This was intended to be more along the lines of Wow there was a screw up that deviated me from a plan, is there something else I can do...like damn the man or something? Assistant: How are you getting punished for it? Youre paying what you owe. If you cant afford it look into setting up a payment plan with the IRS.Human: Sure, we owe it. We were just under the impression that that the bonuses were being taxed appropriately, and the company screwed up. We made a number of deliberate decisions to avoid paying in to FED this year. Then this happened, so it just feels like we are getting punished for her companys screw up.  <response>: it just feels like we are getting punishedIts not at all clear how youre being punished. You will have to pay tax on the amount of the bonus, just as you would have no matter what the company did.The IRS is not likely to charge a penalty in this circumstance, and even if they did, in this case it would be a few bucks.If this is being punished, youve had a very easy life.
