Is there a table to figure out payroll tax withholding percentages?

A table for calculating payroll can be found in Internal Revenue Service Publication 15, the "Employer's Tax Guide." These tables are separated by duration of payroll period, so percentages may be different for employers who pay their workers weekly and employers who pay bi-weekly.

In addition to length of pay period, some other factors that affect withholding percentages are the employee's tax filing status and the range in which their take home pay for the pay period falls. Every employee who falls within a certain range must pay a set dollar amount in withholdings, as well as a percentage for every dollar they receive in excess of the minimum amount to qualify for the bracket.
