what do i need to do ?? Why I didn't notice is that I made more money at new job and worked a lot of overtime I just never noticed.
How unfortunate that you did not notice no tax being withheld on your pay all year. But now you owe. Change your W-4 for 2017!! If the amount you owe is really bad, you can arrange a payment plan with the IRS.
