W-4 Tax Withholding Form

At, we cover everything you want to know about Form W-4 in the following four pages:

So What does W-4 mean? It might mean:

  • A waffle 4-pack OR
  • A brand of washing machines OR
  • A herd of four warthogs OR
  • A place to enter your dependents on a tax return?

Actually, it is none of those things! It is most likely that the "W" in W-4 stands for "withhold" or "withholding", (to take out) but we do not know what the "4" means (or why it is there in the first place!). The W-4 is a tax form that you complete and give to your employer (not the IRS) for federal tax (and some state tax) withholding. It tells your employer how much federal and/or state tax you wish to have withheld from each paycheck in a pay period. Your W-4 affects how big a refund you will get, or how much tax you will owe, when you file a tax return on Tax Day. Withholding is good because it keeps you from paying all your taxes at once when you file your tax return. You can think of it as a "pay-as-you-go" system!

Here is a common myth about tax withholding:

Tax Myth: A Taxpayer has no control over a tax refund or taxes owed amount on a tax return.

Tax Truth: You can change your tax refund or taxes owed amount by adjusting your withholding on a W-4!

There are two reasons why you have to complete a Form W-4:

1. Your employer is required to obtain a Form W-4 from you for payroll purposes. He or she uses the W-4 information to complete and give you Form W-2 so you can prepare and file your tax return. 

2. You can use the form to control how much tax dollars are removed from your paycheck. The amount that is taken out from your paycheck will determine your tax refund or taxes owed by Tax Day.

When to Complete or Update a Form W-4

You can update or complete a Form W-4 one or more times throughout the year. Consider this common myth about when to complete and/or update a Form W-4: 

Tax Myth: You can only complete a W-4 when you start a new job.

Tax Truth: You may prepare or update a W-4 anytime during the year, such as whenever your situation changes or you want to update your withholding adjustments.

Your employer will ask you to complete a W-4 whenever you start a new job. However, there are various life-changing situations which may encourage you to adjust (or update) your withholding, including:

  • Marriage, separation, or divorce
  • Buying a house
  • Having children
  • Losing a dependent
  • Having more than one job
  • Receiving a pay raise
  • Winning the lottery (or another large financial gain)
  • Owing too much in taxes
  • Getting a refund that is too large

Adjust Your Tax Withholding

Adjust your paycheck withholding by claiming allowances (number of withholdings) on your W-4. An allowance helps you determine your tax refund or taxes owed on your tax return. It can also help you determine whether or not you qualify for tax deductions or tax credits.

To determine how many allowances to claim on your W-4 depends on whether you want a tax refund, owe taxes, or be tax balanced (no refund or taxes owed). You may want to start by increasing or decreasing your current allowances by 1 or 2, and then give your employer the new W-4 showing the tax withholding that matches your tax goals. 

If you are not sure if you want a tax refund, owe taxes, or be tax balanced (no refund or taxes owed) when you file your tax return? Use our free W-4 Tax Withholding Assessment Tool. Simply answer a few simple questions and the tool will tell you how to complete your W-4 based on your tax goals! 

More W-4 Information

Check out the topics below so that you will not be saying to yourself, "What is the W-4 For?"

What Your W-4 Information Tells Your Employer

The information OR allowances you enter on the W-4 form tells an employer how much federal (and some state) money to withhold from your paycheck. The money that is withheld pays for federal income taxes. This information will help calculate your net paycheck or how much money you will keep every pay period, after taxes are withheld. You could also earn a tax refund if you end up paying more taxes than you owe annually.

Your employer will use the number of allowances you report on your W-4 to calculate how much income tax to withhold from your paycheck. This withholding is based on your salary and financial situation. For example, if you are married and have one child, you can take two allowances.

The allowances will not only affect the size of your paycheck, it makes an impact on how much you owe to the IRS or how much your tax refund will be at the end of the year.

What Is a W-4 Allowance?

It is a withholding amount you claim on a W-4 form. It helps you determine two things:

  • Your tax refund or taxes owed on your tax return (the primary step to control paycheck withholding)
  • Whether or not you qualify for tax credits or deductions

Types of W-4 Allowances

You can take allowances for yourself, your spouse, and each of your dependents--but that is not all! You may also wish to take allowances for other things, including:

Listing Dependents On Your W-4

This is a common misconception about listing withholding allowances on the W-4. You can claim allowances for other things besides dependents (see list of W-4 allowance items above). That is why the W-4 is called a "Withholding Allowance Certificate," not a "Withholding Dependents Certificate."

How Much Tax to Withhold From Your Paycheck

Let our free withholding calculator help you figure this out! Just enter your tax information (income, filing status, tax credits/deductions, etc.) and the calculator will guide you in determining how many allowances to put on your W-4. That way, you:

  • receive a larger refund (get more of your money at the end of the year) or a smaller refund (get more of your money throughout the year),
  • have little or no taxes due the next time you file your tax return, OR
  • do not owe tax or get a refund.

Get More Money in Your Paycheck

You might want to increase your allowances. However, if you increase your allowances too much, you will end up owing taxes at the end of the year because you did not have enough money withheld.

Get More Money in Your Tax Refund

You might want to decrease your allowances. Whatever you do not owe in taxes you will get back in the form of a tax refund.

But here is something to remember...

A refund is like an interest-free loan to the government. Some people like to use the IRS as a sort of savings account and get a big tax refund, but you could earn more money by simply putting your money into an interest-bearing bank account (the IRS will pay you 0% interest on your money). Furthermore, the value of a dollar will be less next year than it is now, due to inflation.

Get a Refund and Not Pay Taxes

You might want to consider balancing your withholding. This way, your tax refund will come from refundable tax credits and other tax breaks, not from having too much money withheld. Balancing your withholding may require you to adjust your allowances several times during the year.

Allowances to Claim Based on Your Tax Situation 

More allowances = less tax withheld from your paycheck - Try and remember the phrase "More or Less"

Less allowances = more tax withheld from your paycheck - Try and remember the phrase "Less is More"

You do not need a new job to complete or adjust your W-4. However, you might want to consider adjusting it often. Theoretically, you can adjust your W-4 with your current employer as often as you want, but for practical purposes, you should only do this once each pay period (at the most). Your employer might think that adjusting your W-4 more than once per pay period is a bit much.

If you have more than one job you might want to complete each W-4 with the same number of allowances, or report a different number of allowances on each W-4. It generally depends on how much money you want withheld from each paycheck.

If your employer receives a lock-in letter from the IRS denying the amount of allowances claimed on your W-4, your employer is required to use the IRS calculation of allowances instead of the allowances you reported on your W-4. This must be put into place no more than 60 days after your employer receives the letter.

However, if you submit a new W-4 with more taxes that are calculated than what is reported in the IRS lock-in letter, you will be able to claim the allowances you reported on your W-4. Please be aware that this is a very rare exception.
