A 401(k) is a deferred tax saving plan where the employees of an organization/business save a part of their salary in 401(k) funds, for which she/he will not be required to pay taxes until the age of retirement. Here, both the employer and the employee will be allowed to make contributions into the fund. An individual 401(k) plan covers only the business owners, partners and their spouses thus freeing them from the complexities of the ERISA rules.

The contributions under this plan are similar to a general 401(k) plan where the profit sharing contribution is made by both the employer and the employee. Different contribution caps are available for different types of businesses. But, since in most cases, both the employer and the employee are the same, the contribution can be slightly higher. Also, provisions are available for additional contributions for plan holders who are above 50 years of age.

Basic qualification for an individual 401(k)

• An individual claiming to qualify for this plan must have some self-employed income either part-time or full-time.
• This plan can be claimed by an individual from any type of business- single owner, self-employed, partnership, company with limited liability, corporations etc. where she/he should have at least 5% share in the business.

Types of individual 401(k) plans
These are classified based on the documents and the agreement that states and controls the operations of the plan. The employer can customize the plan agreement according to the options available in the basic plan offered by a plan sponsor. A plan sponsor is a company that offers a plan to the employer, either as an individual designed plan or a prototype plan. There are two types of solo 401(k) plans where an investor can select a plan based on her/his investment goals, asset preferences, fee schedules and the level of control desired.
