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 am married and with 1 child. My husband is the head of household and claims both myself and our child. I am going to start working part-time. Can I still claim myself, my husband, and our child if I want more taxes withheld?

    thank you.

    1. If you are legally married within the year that you are filing, you must choose married filing jointly or married filing separately as your filing status. The head of the household claim is no longer a qualified status that you can take. You will only need to file one tax return in the case of choosing married filing jointly, where you and your spouse will be the taxpayers with one dependent child claimed.

  2. Hello…. I am married and a non resident alien and nobody can claim me as a dependent.
    I got a job at my school and was confused on what to fill concerning the total allowance. So I just filled 1…. should I have filled 2 or 1?
    Considering that my spouse can not fill married because I am a non resident alien
    Should I have ticked single and not married?
    Please what’s the right thing for me to do?
    I am so confused.

  3. I am divorced in 2016. I changed my filing status as single on federal W-4 because it doesn’t have head of household status like state W-4. My exemptions are 2 for state and 2 for federal. I am two children’s primary custodian. I noticed I pay a lot more federal taxes now than before or my married co-workers. I do get tax returns but what should be my number of allowance if I want to break even or minimum refund. Also, is this correct that I changed my filing status as single on federal W-4 after divorce?

  4. Hi tax advisor,

    Last year is already said and done and moving forward we would like to change our W4 starting this January so that next year we are prepared. We were married in 2016, bought a house in 2017 and had a child August of 2017. We both claim 0 (not ideal but we just didn’t know ) my husband and I both work and he makes more money than I do. How should we be completing our W4? Who who carry the child as a dependent?

    Thank you!

    1. If you are unsure of whether you will end up owing or having a refund, it always best to claim conservatively when it comes to your number of allowances.

      From the situation that you have outlined, if you are filing married filing jointly, with your child, the number of allowances that you would be able to claim would be around 3-4.

      You can also utilize the IRS’s Tax withholding calculator as well for additional assistance.

      1. 3-4 allowances each? Myself and my husband both can have 3-4 allowances on each of our W-4’s? Or total?
