An employer typically needs a new employee to fill out a W-4 form for federal tax withholding, an I-9 form to verify their eligibility to work in the US, and any other forms required by state and local government agencies. Additionally, the employer may ask for direct deposit information, emergency contact information, and signed copies of company policies or agreements.
