I recognize W-4s are for calculating how much an employer should withhold from an employee for tax purposes. More allowances, less withheld. Less allowances, more withheld. This is the gist of it?
At my company, some employees have filled out W-4s while others have not. I'm confused at what the benefit of this is for the employee vs. the employer?
I honestly didn't realize that some employees do not have to fill out W-4s when on-boarding a job.
