How to Fill Out or Complete a W-4

W-4 Form

The W-4 form or Tax Withholding form is an important part of your paycheck and tax return planning. Your W-4(s) determine, to a great extent, if you can expect a tax refund or if you might owe taxes with your next tax return. A W-4 form is required for each wage or salary earning job and can be changed, adjusted, and submitted to an employer as often as needed. During 2021, the IRS - not eFile.com - delayed many tax return payments, thus managing your tax refund has become even more important. W-4 and Tax Refund details:

  • Manage or reduce your tax withholding throughout the year via the W-4 form and keep your money now and throughout the current year. If you do not optimize your withholding, you are handing over too much in YOUR tax withholding to the IRS only to get YOUR MONEY back again next year via your tax return refund.
  • Did you know that in 2018 over 113 million tax returns resulted in tax refunds in the amount of over $331 billion dollars1)? Tax refunds is not "free" IRS or government money, but it is too much of taxpayer's money handed over to the IRS as a result of too much paycheck tax withholding, which is the result of insufficient W-4 form planning: Reap what you sow, thus get started sowing with proper W-4 or tax withholding planning.
  • Thus, we consider most taxpayer's tax return refunds a self-inflicted financial penalty or wound by the taxpayer.
  • On top of that, according to the IRS, about 1.2 billion dollars in tax refunds are not being claimed by taxpayers each tax year.

Complete, Submit a W-4

If your situation applies to at least one of the following statements, we have the tool for you to complete your W-4:

  • I don't know why I have to fill out a W-4.
  • The W-4 is too complicated, I don't know what to enter.
  • I do not know how the W-4 impacts my tax return.
  • I'm a Tax Geek, just give me the tools and I can do this.
  • Why is this W-4 so complicated?

We at eFile.com believe the W-4 is designed in a way that makes it confusing and complicated for a taxpayer to complete the W-4 to make the outcome transparent.

  • The form is not driver-less!
  • For example, the form does not allow a taxpayer to enter a fixed, per pay period tax withholding amount!
  • Plus, even if you complete the form, it does not tell you what your paycheck tax withholding amount will be.
  • The eFile.com W-4 Adjust and W-4 Pro tools are addressing all these points unlike the W-4 Basic (not intended for it).

Thus, select any of the four W-4 tools based on your personal tax planning needs and comfort level.

Important: The W-4 is your planning tool to manage your tax withholding per paycheck. You submit your W-4 ONLY to your employer for any one given job for the purpose of IRS tax withholding. The W-4 is NOT submitted to the IRS or state tax agency! If you and/or your spouse have multiple jobs at any given time, complete a W-4 for each job separately. In addition, check the state tax withholding requirements for the state where you reside or work.

Since the W-4 is a planning tool, you can adjust your entries for tax withholding purposes. In comparison, you can NOT do this on your tax return as a tax return must be accurate (number of dependents, deductions, income, etc.).

Privacy Statement: The data you enter on the W-4 will NOT be stored or shared with anybody!

Since employees and taxpayers have different experience levels when it comes to the W-4, we have created a solution for each scenario. Start with one of the options listed below. If you are not sure, contact an eFile.com Taxpert® so we can guide you through this.

In summary, we at eFile.com recognize the complexity of the design of the W-4 Form and we are here to assist you at every level. We consider the W-4 Form an important part of your financial and tax return planning. For many reasons, taxpayers have experienced IRS related tax return processing delays in 2021 - not eFile.com delays. These delays have held up tax refund payments for too many taxpayers, thus W-4 planning is important as taxpayers create their own tax return refunds if they withhold too much in taxes per pay period. Manage or reduce your tax withholding now via the W-4 and keep your money now and throughout the current year instead of handing over too much in your tax withholding to the IRS. At the end of the year, you are only to getting that same money back again via your tax return refund.

We sympathize with you: If you think that completing a W-4 Form is worse than a dental root canal procedure, we totally get IT! Unfortunately, we do not do root canals and can only help you with the W-4 forms.
