IRS Form W-4 for 2015 – 2016

IRS Form W-4 determines how much tax should be withheld from your Federal income tax. The amount to withhold should match the amount you will be required to pay.

UNLV is not permitted to provide tax advice to its employees. You should consult a tax consultant for details on how much to withhold from your taxes, depending on your current situation.

The IRS does provide a withholding tax calculator to aid in completing your Form W-4.

With the year winding down, you may want to take a few minutes to make sure what is being withheld from your paycheck matches your actual tax liability.

If you’re having too much tax withheld, that’s money you can’t use until you get your refund. If you’re not having enough withheld, you will owe tax at the end of the year, and you may even have to pay a penalty. Generally, a penalty will apply if your withholding and estimated tax payments total less than 90 percent of your current year’s tax liability and less than 100 percent of the previous year’s tax.

You should pay particular attention to your withholding if you received a big refund check this year or if you had to make a tax payment that was more than you could comfortably pay.


Also check your withholding if you had a significant change in your life this year, like marriage, divorce, birth or adoption of a child, purchase or sale of a home, or retirement. And there is a good chance you’re not having enough withheld if you have more than one job, your spouse works, you have income not subject to withholding, such as rent, dividends, interest or capital gains, or you owe other taxes like self-employment or household employment taxes.

You can adjust the amount withheld from your paycheck by giving your employer a new Form W-4, Employee’s Withholding Allowance Certificate.

IRS Withholding Calculator 2015 – 2016

If you are an employee, the Withholding Calculator can help you determine whether you need to give your employer a new  Form W-4, Employee’s Withholding Allowance Certificate to avoid having too much or too little Federal income tax withheld from your pay. You can use your results from the calculator to help fill out the form.

Who Can Benefit From The Withholding Calculator?

  • Employees who would like to change their withholding to reduce their tax refund or their balance due;
  • Employees whose situations are only approximated by the worksheets on the paper W-4 (e.g., anyone with concurrent jobs, or couples in which both are employed; those entitled to file as Head of Household; and those with several children eligible for the Child Tax Credit);
  • Employees with non-wage income in excess of their adjustments and deductions, who would prefer to have tax on that income withheld from their paychecks rather than make periodic separate payments through the estimated tax procedures.
