A 401(k) is a qualified retirement plan companies offer employees as part of their benefits package. Through this plan, an employer matches an employee’s contribution towards their retirement fund. Though it is not legally required, many companies offer 401(k) plans to become eligible for tax benefits. Employers are, in many cases, given exemptions for state and payroll taxes, whereas the contributions made by the employee are considered deductions from their federal income tax.  Common mistakes people make with their 401(k) plan 1. Not knowing the different 401(k) accounts Before signing up for a 401(k) plan, it is important to know the characteristics and features of the different 401(k) accounts so that one can plan one’s savings accordingly. This scheme offers two types of accounts – Traditional 401(k) and Roth 401(k). One can choose the account that is suitable for one’s needs. The basic difference is that in a traditional 401(k), the contributions are made with pre-tax income, while in a Roth 401(k), it is made after-tax income. Roth 401(k) is currently more popular as it offers better tax benefits and wider investment options. 2. Withdrawing early from the 401(k) The 401(k) plan is designed to be a retirement-support fund; hence, checks and balances are in place to deter the use of the funds before retirement.
