What Is a W-9 Form and How Is It Used? A Guide

IRS Form W-9, Request for Taxpayer Identification Number and Certification, is used by businesses to get tax information from external parties. The information provided on Form W-9 informs the company of what information to include in the Form 1098 or Form 1099.

Let’s take a look at who is required to fill out a W-9, what information is required, and the purpose of the form.

Purpose of Form W-9

The purpose of a W-9 is to gather tax information from a vendor. When a company pays a non-employee or other entity money more than $600 in a year for their service, the company must file an information return. To ensure the information return is accurate, the purpose of a W-9 is to gather all required information directly from the vendor.

While some information is publicly available, Form W-9 protects the company trying to obtain the information by requiring the other party to sign the filled-out form. The signature certifies:

• the tax identification number (TIN) being provided is correct.
• the other party is not subject to backup withholding.
• the other party is claiming exemption from backup withholding.
• the FATCA code used by the vendor (and the vendor’s exemption status)

Businesses use the name, address, and Social Security number or tax identification number contractors provide on Form W-9 to complete that information return. Neither the sender nor the recipient should send a copy to the IRS. In addition, the business requesting the tax information must safely secure copies of the form.

Uses of Form W-9

The Form W-9 is used to prepare a range of various informational returns to the IRS. The most common situation occurs when an independent contractor completes work for a company and receives payments. If that independent contractor receives more than $600 in a calendar year, they are required to be sent a Form 1099-MISC and self-report their own taxes.

The purpose of a Form W-9 extends beyond just this single situation. A bank or financial institution relies on the receipt of taxpayer information in order to property report Form 1099-INT, 1099-DIV, or 1099-B. A taxpayer may also be asked to furnish a Form W-9 for cancel debt, student loans, or real estate transactions.

Who Needs To Fill Out Form W-9

If you’re an employee, your employer will withhold income taxes, withhold and pay Social Security and Medicare taxes, and pay unemployment tax on your wages. You’ll receive a W-2 that summarizes your earnings. Instead of filling out a Form W-9, new hires are often asked to fill out a W-4 to provide their taxpayer information to their employer.

If you’re an independent contractor, it won’t. That means you’ll be responsible for the employer’s share of Social Security and Medicare taxes, and that you won’t be eligible for unemployment compensation if you are laid off. To report some of this related information to the IRS, independent contracts, freelancers, and other non-employees that received payments should fill out a Form W-9.

Financial institutions may ask a new client to fill out a W-9 as it is a useful way of collecting and recording a customer’s details. Real estate businesses may also ask tenants to complete a W-9 as a method of storing their information as well.

Information Needed on Form W-9

Form W-9 asks the independent contractor for eight pieces of information:

• Line 1, Name. This is the name that is shown on the individual’s tax return. This field is required. This field is either the name of an individual, although it can be the name of the owner of a sole proprietor. The taxpayer can also list the name of a partnership or other entity.
• Line 2, Other Business Name. This line is only required if the taxpayer has a business name, trade name, DBA name, or disregarded entity name.
• Line 3, Federal Tax Classification. The taxpayer must select whether they are a corporation, individual, sole proprietor, single-member LLC, limited liability company, partnership, or trust/estate. The taxpayer must only select one of the options provided.
• Line 4, Exemptions. The taxpayer must select whether they are exempt from backup withholding or FATCA reporting.
• Line 5 and Line 6, Address. The taxpayer must enter their address, city, state, and ZIP code. This is where
• Line 7, Account Numbers. This option field is where the taxpayer can enter in additional information at the requestor’s ask. For example, a bank or brokerage firm may ask the client to enter into their client information here.
• Part I, Tax Identification Number. The purpose of a W-9 is mainly to obtain this tax number from the taxpayer. This may be a Social Security number of an Employee Identification Number.

Upon the completion of the information above, the taxpayer must sign the form under Part II (Certification). As Form W-9 requires listing a tax ID or Social Security number, both the person filling it out and the company receiving the completed form must guard it carefully during transmission and after receipt to protect against identity theft.

Penalties for Non-Compliant Form W-9 Use

The IRS has outlined several penalties for failure to furnish or comply with the reporting requires of Form W-9. If the taxpayer fails to furnish a correct tax number, the taxpayer is subject to a $50 file for every instance of non-compliance of tax law and regulation. This penalty can be waived if the taxpayer can prove the non-compliance was not due to willful neglect.

A taxpayer can also be subject for civil penalty for providing incorrect information that leads to incorrect withholding. If the taxpayer makes a false statement that results in no backup withholding, they’re subject to a penalty up to $500. Penalties get worse upon further non-compliance, as the taxpayer can be subject to criminal penalty in certain cases. Willfully falsifying any information or affirmations subjects the taxpayer to fines or imprisonment.

The requestor of the taxpayer information is not exempt from penalties either. If the requestor discloses or uses the the taxpayer’s TINs in violation of federal law, the requestor may be subject to civil or criminal penalties.

Other Considerations

An independent contractor who receives an unexpected W-9 should hesitate before filling it out and research whether the requester has a legitimate reason to ask for this form. Financial institutions sometimes use Form W-9 to request information from a customer when they need to report dividends or interest. Be careful here: The financial institution should probably already have your tax ID number from when you opened the account.

Another situation in which you should hesitate before filling out Form W-9 is if the company asking you to do so is your employer and you are supposed to be classified as an employee, not an independent contractor.

An unscrupulous or financially struggling employer might try to classify an employee as an independent contractor to save money. If you’re classified as an independent contractor, your employer’s tax “savings” will come out of your pocket as self-employment tax. You’ll also become responsible for calculating and paying your estimated taxes four times a year and filling out Schedule C when you file your annual tax return.

The Bottom Line

W-9 forms are used in may different situations, often for independent contractors or freelancers. It’s important to fill out the form correctly as you may be subject to penalties if it is completed incorrectly. However, all of the information should be relatively easy for you to obtain. Be mindful of how you distribute the form to the requesting party, and take care of protecting your sensitive information and accurate tax reporting status.
