Your total tax bill is your total tax bill. What was withheld during the year was an estimate based on how you filled out your withholding forms. You had too little withheld. You can increase your withholding. It won't lower how much you pay each year in taxes, but it will help you avoid a year-end surprise. Beyond that, you can try to make more money, advocate for lower taxes (and fewer government services as a result), or try to take advantage of more tax incentives.
