Maximizing Retirement Savings with Solo 401(k) Plans: Essential Insights

What is a Solo 401(k)?
A Solo 401(k), also called an individual or Uni-401(k), is a retirement savings option designed for self-employed professionals and sole proprietors. Under Internal Revenue Code Section 401, it offers a cost-effective, tax-advantaged way to grow retirement funds. Ideal for freelancers, consultants, and real estate agents, this plan allows rollovers from traditional IRAs and other qualified retirement accounts, either via a new trust or by transferring to an existing custodian.

Advantages of a Solo 401(k):
Contributions benefit from tax advantages, allowing earnings to grow tax-deferred until withdrawal. Its flexible design reduces administrative overhead compared to traditional plans. Filing Form 5500 is needed only if assets surpass $250,000, simplifying compliance. Contributions are immediately vested with no vesting schedules. Spouses and partners can also contribute, increasing tax-deferral opportunities. Funding options include salary deferrals and profit sharing. Borrowing from the plan is permitted under specific rules.

Withdrawal rules include:
Distributions are only allowed after employment ends or at retirement. Early withdrawals before age 59½ face a 10% penalty. Distributions without RMDs are taxed at 20%. Owners with a 5% stake must start RMDs at age 70½ or face a penalty of 50%. For 2017, contribution limits are $54,000 or $60,000 for those over 60. Assets over $250,000 require filing Form 5500.
Funding deadlines involve establishing the plan by December 31 or year-end, making salary deferrals by the business’s year-end, and profit-sharing contributions by the tax filing deadline, including extensions.
