Small business owners have more retirement plan choices than ever. The key is finding the option that fits your business size, cash flow, and long-term goals while keeping administrative burdens manageable.
1. Traditional and Roth IRAs
Best for: Solo entrepreneurs without employees
Individual Retirement Accounts (IRAs) are the simplest retirement savings option. Traditional IRAs offer immediate tax deductions but require RMDs at age 73. Roth IRAs use after-tax dollars but provide tax-free withdrawals in retirement.
- 2025 Limits: $7,000 ($8,000 if age 50+)
- Pros: Easy setup, wide investment choices, no employer requirements
- Cons: Low contribution limits, income restrictions for Roth
2. SEP IRA (Simplified Employee Pension)
Best for: Self-employed individuals and small businesses wanting higher contribution limits
SEP IRAs allow employers to contribute up to 25% of compensation or $70,000 (whichever is less) for 2025. All eligible employees must receive the same percentage contribution.
- Pros: High contribution limits, flexible funding, minimal paperwork
- Cons: Mandatory equal contributions for all employees, no catch-up contributions
3. SIMPLE IRA
Best for: Businesses with up to 100 employees wanting a low-maintenance plan
SIMPLE IRAs combine employee salary deferrals with required employer contributions—either matching up to 3% or a 2% non-elective contribution for all eligible employees.
- 2025 Employee Limit: $16,500 ($20,000 if age 50+)
- Pros: Easy setup, no Form 5500 filing, employee-owned accounts
- Cons: Lower limits than 401(k)s, mandatory employer contributions
4. Solo 401(k) Plan
Best for: Business owners with no employees (except spouse)
Solo 401(k)s offer the highest contribution potential by combining employee deferrals ($23,000 + $7,500 catch-up) with employer contributions (up to 25% of compensation), totaling up to $76,500 for those 50+.
- Pros: Highest contribution limits, Roth options, loan provisions
- Cons: Form 5500-EZ required when assets exceed $250,000
5. Safe Harbor 401(k) Plan
Best for: Small businesses with employees wanting to avoid nondiscrimination testing
Safe Harbor 401(k)s automatically pass IRS testing by meeting minimum employer contribution requirements—either matching up to 4% or 3% non-elective contributions.
- Pros: No testing headaches, higher participation rates, startup tax credits
- Cons: Mandatory annual contributions, higher admin costs
6. Profit-Sharing Plan
Best for: Businesses with variable cash flow wanting flexible contributions
Profit-sharing plans let employers make discretionary contributions up to 25% of each participant’s compensation, with no obligation to contribute every year.
- Pros: Complete contribution flexibility, can reward key employees
- Cons: Unpredictable benefits, potential underfunding
7. Cash Balance Plan
Best for: High-earning business owners near retirement
Cash Balance Plans combine features of pensions and 401(k)s, often allowing contributions exceeding $200,000 annually for older, high-income owners.
- Pros: Massive contribution potential, predictable growth formula
- Cons: Complex administration, requires annual actuarial valuations
8. Defined Benefit Plan
Best for: Owners wanting guaranteed retirement income and maximum tax deductions
Traditional pensions promise specific retirement benefits, with contributions determined by actuarial calculations. Older owners can often contribute $200,000+ annually.
- Pros: Guaranteed retirement income, substantial tax deductions
- Cons: High costs, rigid funding requirements, complex compliance
9. Pooled Employer Plan (PEP)
Best for: Small businesses wanting 401(k) benefits without administrative burden
PEPs let multiple unrelated employers join a single plan managed by a Pooled Plan Provider, sharing costs and compliance responsibilities.
- Pros: Reduced administration, economies of scale, professional management
- Cons: Less customization, dependence on provider quality
10. Employee Stock Ownership Plan (ESOP)
Best for: Owners planning succession while rewarding employees
ESOPs give employees company stock ownership, serving as both a retirement plan and succession strategy with significant tax advantages for selling shareholders.
- Pros: Tax-efficient ownership transition, aligns employee interests
- Cons: Requires annual valuations, concentrates retirement savings risk
Choosing Your Strategy
Consider these factors when selecting a plan:
- Business size and employee count
- Cash flow consistency
- Desired contribution levels
- Administrative capacity
- Tax planning objectives
Many owners combine multiple plans to maximize benefits. For example, pairing a 401(k) with profit-sharing or adding a Cash Balance Plan for additional savings.
