Number of Federal Allowances
How many federal allowances are allowed ?
According to the US Internal Revenue Service a person can enter as many allowances as is needed in the federal W-4 form. However entering more than 9 allowances will cause the employee’â„¢s human resources department to get a request for verification from the IRS. The number will vary depending mainly on the number of dependents one has and whether employment is full or part-time.
