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. Is this page still being followed up on? I had a question, I’m not married an working a part time job. I claimed 0 on my W2’s. Did I fill wrong? Will i have to pay in at the end of the year? Also what kind of refund will result in claiming 0?

    1. Hi Mariah,

      Yes, we are still replying to comments throughout this entire blog. When claiming zero allowances on your W-4 form, you are allowing your employer to withhold the maximum amount of income from your paychecks to be applied to tax owed to the IRS throughout the year. If too much is withheld throughout the year, the IRS will issue a refund. Based on what you mentioned above, you will most likely receive a tax refund since the maximum is being withheld from your paychecks.

  2. I am unmarried, with one child. I work and take care of 90% of our home expenses. I prefer to have the biggest tax return i can get. How many allowances should I claim?

    1. Hi Patrick,

      In order to receive the highest refund possible from the IRS, you can claim zero allowances on your W-4. Keep in mind that the lower the amount of allowances you claim, the more is withheld from your income throughout the year; meaning that you will have less take-home pay. When excess is withheld throughout the year, that is when the IRS will issue a refund.

  3. Hi

    I am married and have twin girls. I will quit my job on the 6th of January 2017 to take care of my daughters. My husband will be the only one working for rest of the year. what is the number of allowances he should claim on his W4 moving forward ? He is also resigning from his current job on the 6th of January to start a new one on the 16th of same month.

    Thanks

    1. Hi Med,

      If you would prefer your tax situation to remain consistent (for the most part) when it comes to receiving a refund or owing after filing, then your husband should add the allowances that you were claiming on your W-4 form to his own W-4. If he would prefer to receive more take-home pay instead now that only he is earning an income, then he should increase the amount of allowances he is claiming. Keep in mind that the more allowances he claims, the less will be withheld from his income; in turn possibly causing him to owe the IRS after filing for the year.

  4. Hi,
    I would like to know what happens if we do fall in the “If you are single and have more than one job or are married and you and your spouse both work and the combined
    earnings from all jobs exceed $50,000 ($20,000 if married), see the Two-Earners/Multiple Jobs Worksheet on page 2
    to avoid having too little tax withheld” category but miss providing the details and instead fill the form with 4 and 0 claims individually

    1. Hi Sam,

      It is only suggested to complete these worksheets on your W-4 form. If you happen to forget or do not prefer an additional amount be withheld from your paychecks throughout the year, you may owe the IRS additional tax after filing your return for the year. There is no penalty for not completing the worksheet. It is 100% optional.
