What is the minimum percentage of income that will be withheld from a employers paycheck?

The minimum percentage of income that can be withheld from an employee's paycheck varies based on several factors, including federal, state, and local tax laws, as well as employee benefits and deductions. Typically, federal income tax withholding is based on the employee's earnings and exemptions claimed on their W-4 form, and can range from 0% to a higher percentage. Additionally, Social Security and Medicare taxes are also withheld at fixed rates (6.2% and 1.45%, respectively). Therefore, there isn't a single minimum percentage, as it depends on individual circumstances.
