How to Fill Out a W-4 Correctly

Filling out a W-4 is less mind-boggling than you think.

One of the first things you have to do when you get a new job is filling out a Form W-4 [Employee’s Withholding Allowance Certificate]. It is essential to complete a W-4 correctly because it determines how much tax will be withheld from your pay and how large your tax refund will be.

The first half of the form is pretty easy. You just have to fill in your name, address, and marital status.

Then you have to figure out how many allowances to claim. This number will determine the amount of your withholding.

Number of allowances to claim

Generally, the number of allowances you should claim will correspond to the number of personal and dependency exemptions you can claim on your tax return, but this is not always the case. Claiming zero allowances will result in the maximum amount of tax withheld. Every additional allowance you claim on top of that means that a little less tax is withheld.

You’re a Dependent:

If you can be claimed as a dependent on someone else’s tax return (ie: your parent’s, aunt’s, etc.), you should claim zero allowances. When you’re a dependent, the person who claims you get the benefit of your personal exemption and you, yourself, will end up owing slightly more in taxes. Hence, the tax should be withheld at the maximum rate of zero allowances.

You are Single: 

As a single taxpayer, your W-4 form is straightforward enough but you do have several options when it comes to claiming allowances.

  • If you’re single with one job, the allowances to exemptions ratio don’t exactly hold true. Most single people claim one allowance. However, this is likely to result in a refund. If you prefer the extra money after filing, then claiming one allowance is the choice for you.
  • Claiming two allowances would get you closer to your exact tax liability, but may actually result in some tax due. That being said, you would have more take-home pay throughout the year since your employer wouldn’t be withholding as much tax from your paychecks.

Essentially you can choose whether to claim one or two, depending on the rest of your tax situation, but it’s probably safer to claim one.

You are Married: 

Have you tied the knot? This can drastically change your tax situation. Don’t worry; it’s typically for the better. Being married opens up a few doors for you when it comes to tax benefits. You can now file a joint tax return. This is the absolute ideal filing status in regards to taking advantage of your benefits as a taxpayer. In most cases, being married also allows you to claim more allowances on your W-4.

  • If you are married with no children, you should claim two allowances.
  • If you are married with one child*, you should claim three allowances.
  • If you are married with two children*, you should claim four allowances.

*Check your eligibility to claim the child tax credit. This gives you more money after filing but also allows you to claim additional allowances on your W-4.

Other Situations: 

Things get a little more complicated if you have multiple jobs, your spouse works, or you intend to itemize your deductions. In these cases you should turn your attention to page two of the W-4:

  • Deductions and Adjustments Worksheet: Use this worksheet if you plan to itemize deductions on your tax return or claim adjustments to your income.
  • Two-Earners/Multiple Jobs Worksheet: You will be directed to use this worksheet from the Personal Allowances Worksheet, line h. It is only necessary if you are married and earning a combined income of over $20,000 or if you are single with two jobs earning over $50,000.

The IRS also has a withholding calculator on their website that can give you a second opinion on how many allowances to claim.

The last thing you need to do is figure out if you are exempt from withholding. For most, this is not the case. Essentially, you are only exempt from withholding if all of the following is true:

  • you aren’t a dependent,
  • you had the right to a refund of all income tax withheld last year, and
  • you are not required to file a return this year.

If you are exempt, you can write exempt in line seven. You’re done! All you have to do now is sign the form and hand it over to your employer.

Update Your W-4 For A Larger Refund or More in Your Paycheck

Even if you’ve been at your job for a while, it’s a good idea to monitor and, if necessary, update your W-4 every year. This is especially true if there’s been a major event in your life such as a marriage or the birth of a child.

The goal is to get your refund or tax due as close to $0 as possible. Getting a big refund when you file taxes is a great feeling. It can also trigger that your withholding needs to be adjusted. The reality is that you could be enjoying that money throughout the year instead of having it withheld from your paychecks.

Regardless, during tax season you’ll need to report the total earnings and tax withheld on a tax return. Use RapidTax to file your taxes without a hassle and receive the maximum refund possible!

  1. Hello,

    I got married last year and have not updated my W4 with my job. I need to update my federal w4 as well as state w4. I recently moved from Texas to Colorado last month and since Texas did not have state Tax I have no clue how to fill that out for Colorado. Here is my situation for 2017:

    Married filing jointly with no kids in state of Colorado.
    I work and my husband was unemployed at the beginning of the year, however he just recently got a job that he will start in a week or 2.
    I am paying on student loans currently but do not have access to how much interest I have paid at the moment (locked out of my account).

    How many allowances should I claim and how much should he claim when he fills out his w4s?

  2. Hello,

    I am very new to this and from reading/researching, it seems that I have been filing my taxes incorrectly. I am a single (head of the household) with 1 parent dependent. I was wondering if I should file 1 or 2 for exemption or allowance? I don’t really understand the difference and I do not mind not receiving a refund check as long as I do not owe.

    Also, how would I file my “special allowance” for my passive income with my rental home that is generating a loss every year?

    Thank you.

  3. Hi, I am single w/ one dependent & I file head of household.
    Currently I have 6 exemptions on my w4, which I think may be too much.
    I would really like to make an adjustment.. how many should I have? Thanks

    1. Please consult with your payroll department, as they will be able to better assess your situation and advise you on it. If you are indeed receiving too much of a refund every year as you have been filing with these values on your W-4, you may need to claim less allowances.

  4. I have 2 jobs I know your suppose to put 1 allowance on the highest paying job and 0 on the lowest. But my question is would it be alright if I put 0 on both. Thanks.

    1. Hello Manuel,

      You may that on your W-2. Claiming allowances is entirely up to the taxpayer. Please keep in mind that claiming zero allowances means the maximum amount of tax will be withheld from each paycheck. This will possibly result in you getting a refund.

  5. Hi, I am an international student (single) at IL and have a graduate assistant-ship for 9 month period. This summer I am going to teach a course at New York and need to fill out my W4 form along with my NY state tax form. Would you please tell me how many claims I should claim on my w4 form. If i am going to put 1 on line 5 then do I still need to fill the line 6 or I can put it blank. I appreciate your suggestions. Thanks

    1. You must consider several conditions in order to determine what allowances you should claim on your W-4 form. Here is a link to the IRS Withholding Calculator that can help you figure what you should claim on your W-4. Line 6 on your W-4 is for an additional amount that you would like to be withheld from your paycheck. This amount is optional.
