I had to pay this last year. I don't understand why not enough taken out. I have no deductions for myself.  How do I know how much to adjust this so I won't owe next year.

Our W-4 Calculator is a great tool.   The IRS also offers an estimator.  I also want to mention that if you have multiple jobs through the year giving you multiple W-2s, this can be an issue.  The different jobs don't know about the other jobs, so to speak.  When you work for a company, the payroll software usually looks at what you're on track to earn for the year.  Each company's software would have no idea about the other earnings.  You can adjust for this by completing the multiple jobs worksheet included with the W-4 form to arrive at a number to put on Step 4(c) for extra withholding each pay period.  Most folks just pick the highest paying job to have the extra withheld from.  

@Katheryn Hope this helps!
