Apparently for 2019, my employer had me marked as excempt from federal taxes on my W4 since February 2019. I never even submitted a W4 with that checked off, so I'm really upset with them. For 2018 I had no tax liability and got everything back since it was my first year working, but because of the exception in 2019, I owed $316. I didn't realize any of this until I got my W2 in the mail this January. I updated my W4 the next day and filed the taxes and paid the amount due, but I read there could be a $500 fine for incorrectly claiming excempt. Since I already corrected everything, is anything likely going to come from this? Am I going to get penalized the $500? Thank you in advance, I've been worried sick ever since i discovered this problem.
