Get your taxes done using TurboTax

Ask your employer or HR dept.  You might not be making enough on each paycheck to have withholding taken out.  They did reduce the withholding tables to give you more back in your paychecks but then you get a less refund (or owe) on your tax return.   

 

You can increase your quarterly estimated payments to cover it.  Or have more withheld on your other W2 job.
