Who would have more federal income tax withheld from emploee's paycheck with allowances?

An employee who claims fewer allowances on their W-4 form will have more federal income tax withheld from their paycheck. This is because fewer allowances indicate a higher tax liability, leading the employer to withhold a larger portion of the paycheck for taxes. Conversely, an employee who claims more allowances will have less tax withheld, reflecting a lower tax obligation. Therefore, the number of allowances directly affects the amount of federal income tax withheld.
