filed exempt on w4 and shouldn't have
I'm 17 and entered exempt on my w4 because I didn't think I would earn more than 10K. once I discovered I was going too, I tried to change my W2 but my employer wouldn't change it right away because they were changing payroll systems. I ended up earning over $15K but my W2 says less than $1K. What do I do to make sure I pay the correct taxes?
