401(k) Plan Eligibility

Generally, any business may have a 401(k) plan. In establishing a plan, the employer sets the eligibility requirements. For example, employees under the age of 21 or who have not accrued one year of service may be excluded.

Tax Advantages

As an employer, you normally can deduct contributions you make on behalf of your employees from your business expenses.

Any eligible employees may elect to defer part of their salary and direct that money into 401(k) accounts. Because these contributions are deferred before certain taxes are withheld, they actually reduce contributing employees’ taxable income. Any earnings within the account enjoy tax-deferred growth until withdrawn.

Solo 401(k) Spotlight:

Employer contributions to a Solo 401(k) are tax-deductible, plus salary deferrals are deductible, benefiting both your business and you!

Employees can also elect to defer part of their salary into a Roth 401(k) account.  Roth 401(k) account contributions do not reduce an employee’s taxable income, however qualified distributions (including earnings) are tax-free.

Establishment Deadlines

Employers who want to establish a 401(k) plan must do so by the last day of the plan year (usually the calendar year).

Safe-harbor plans must be established by October 1st.
