A 401(k), which is a savings account that is set up by a business to help employees or self-employed people save for retirement, and to take advantage of tax benefits offered to both the owner and employees, is called a 401(k). Flexible features in a 401k can be tailored to meet a wide range of retirement planning goals. Every individual has the option to decide how much of their paycheck will be deposited into their account 401(k), before taxes are deducted, and how they will invest those dollars. Many companies match employees' contributions to help their retirement savings grow faster. A 401(k), in addition to financial security, provides tax benefits for both the employer and employees. This includes tax deductions, tax deferred earnings and tax credits. When an employee saves in the 401(k), it is taken from their paycheck before income taxes.
