Who needs a W9 tax form?

Those who should fill out a W 9 are those who are working as independent contractors or freelancers, because the W-9 is the form used by the IRS to help gather information about such workers. The W-9 form is an informational reporting tax form, meaning that it provides information to the IRS about taxable entities.
What happens if I don’t fill out a W9?
If you don’t fill out a W-9 duly requested by an employer, partner or other entity duly entitled to your taxpayer ID information, you may be penalized $50 for each instance. You may also be subject to backup withholding, which means the payor will withhold 28 percent of your check and forward the proceeds to the IRS.
Where does the income come from on a W9 form?
All the data presented on a W-9 form comes from IRS tax form 1099, which lists any income paid out to an individual that otherwise would be recorded on an IRS W-2 tax form. This W-9 form is meant for self-employed workers like freelancers, independent contractors and consultants.
When do I need to submit a new W-9 form?
You will also have to submit new W-9 forms any time you change your name, business name, address or tax ID number. Most of the time, a company or financial institution will send you a blank W-9 form to complete before you begin business with them. If you need to issue the form, you can download a W-9 from the IRS website.
What’s the purpose of the IRS Form W-9?
Use Form W-9 to request the taxpayer identification number (TIN) of a U.S. person (including a resident alien) and to request certain certifications and claims for exemption. (See Purpose of Form on Form W-9.) Withholding agents may require signed Forms W-9 from U.S. exempt recipients to overcome a presumption of foreign status.
Do you need a tin to file a W-9?
