What government form must be filled out accurately, or it may be sent back?

The I-9 form is crucial for verifying the identity and employment authorization of individuals hired for work in the United States. It requires the employee to provide specific documentation that proves their eligibility to work, such as a driver's license and social security card or a passport. If this form is not filled out accurately or completely, it could lead to significant delays in processing and may result in the form being returned for correction. This form is mandated by federal law, and employers must maintain correct and complete records to comply with immigration laws. Therefore, ensuring that the I-9 is filled out correctly is essential to avoid any operational setbacks.

The other forms serve different purposes: W-2s document wages earned and taxes withheld for employees, 1099s report income earned by independent contractors, and W-4s indicate the employee's tax withholding preferences. While accuracy is important for all these forms, the I-9 specifically requires careful attention to detail regarding the authorization to work, making it distinct in this context.
