How to fill out the W-9 Form: Steps and common mistakes


The W-9 Form is one of the many forms requested by the IRS (Internal Revenue Service) for those who are self-employed. For example, if you are an independent contractor, it is not always necessary to fill out the W-9 form for employees, as it depends on the amount of annual salary you receive.

What is the W-9 form?

As mentioned above, the W-9 form is a document that is used by self-employed workers to show the IRS all the information about service providers, such as the name of the company or person in charge, their address or tax identification number.

IMPORTANT: This form should be completed only by employers of a business.

How to obtain the W-9 form?

You can obtain your W-9 form from the same company where you work and provide services, or from the financial institution where you have an account or applied for a loan. These are the agencies in charge of providing you with the IRS form for you to complete with the required data.

This way, you will be able to keep a record of all the payments you made to the employee, and, in addition, it serves to file taxes. To do this, as an employer, you will need to gather all of your employees’ W-9 forms and fill out your 1099-MISC form.

On the other hand, you may be asked for this document when buying or renting an apartment. Also, financial institutions, such as banks, may ask you to fill out the W-9 form in order to inform the IRS about the amount of money you receive for dividends and interest, or when you need to open a bank account, apply for a loan or a credit card.

At irsofficenearme.com we have prepared a list for you so that you can avoid the most common mistakes that people make when filling out the W-9 form. Let’s take a look at some of the most common mistakes below:

  • Mistakes when spelling your name or DBA (Doing Business As), if you are a business. These mistakes could end up in an audit because, to the IRS, you would not have reported your tax return on your 1099-MISC form when you send it in later.
  • Email address errors. It is important that you verify that your e-mail address is correct, since you will later receive the 1099-MISC form through this means. This is why, if you misspelled your e-mail address, you will not receive the PDF of the form.
  • Typing errors when entering your Social Security Number (SSN) or Employer Identification Number (EIN).

REMINDER: Your employee will not be aware of these errors, as he or she does not have access to verify the data you have entered on the W-9 form.

  • Make sure you have entered all the information correctly to avoid possible problems, even with the courts.
  • Once you complete your information properly, you will be able to make sure that the payments are reported to the IRS correctly and without errors.
  • In case you have doubts regarding any of the fields to complete, we recommend that you consult a specialized financial advisor.
