I-9 Form vs. W-9 Form: Key Differences and When to Use Each
The I-9 Form is used to verify the identity and employment authorization of individuals hired for employment in the United States. The W-9 Form is used by independent contractors to provide their tax identification number to the entity paying them.
People often mix up these forms because both are related to employment and taxes. However, the I-9 is for employees, while the W-9 is for independent contractors. The confusion arises from their similar names and the fact that both are IRS forms.
Key Differences
The I-9 Form is filled out by employees to prove their eligibility to work in the U.S., whereas the W-9 Form is completed by independent contractors to provide their taxpayer identification number to clients. The I-9 is maintained by the employer, while the W-9 is kept by the payer.
Which One Should You Choose?
Choose the I-9 Form if you are hiring an employee. Choose the W-9 Form if you are hiring an independent contractor. If you’re unsure, consider whether you control the worker’s schedule, tools, and tasks. Control suggests an employee (I-9), while independence suggests a contractor (W-9).
Examples and Daily Life
For example, if you’re hiring a full-time office assistant, you’ll need them to complete an I-9 Form. However, if you hire a freelance graphic designer for a specific project, you’ll ask them to fill out a W-9 Form.
What happens if I use the wrong form?
Using the wrong form can lead to legal and tax issues. The IRS may penalize you for incorrect classification of workers. Ensure you understand the differences to avoid these problems.
Can a worker fill out both forms?
Yes, a worker can fill out both forms if they are employed by your company and also providing services as an independent contractor. However, this is quite rare and should be carefully managed.
