Quick Answer
Hiring employees eliminates Solo 401(k) eligibility and requires including all workers in retirement plans. A freelancer earning $100,000 who could contribute $69,000 solo might face $8,000-25,000 in annual employee retirement costs depending on the plan chosen.

Established freelancers earning $75K+ who are thinking about hiring their first employee but worried about the impact on their retirement savings
The immediate impact: Solo 401(k) is gone
The moment you hire your first non-spouse employee, you lose eligibility for Solo 401(k) plans — often the most powerful retirement savings tool for high-earning freelancers. This single change can reduce your maximum annual retirement contribution from $69,000 to as little as $7,000.
What you lose with Solo 401(k)
2026 Solo 401(k) limits (lost when you hire):
Your new options with employees
Option 1: SEP-IRA (Equal contributions required)
Option 2: SIMPLE IRA (Employee deferrals + matching)
Option 3: Traditional 401(k) (Maximum flexibility, maximum complexity)

What you should do before hiring
1. Model the total cost: Calculate retirement contributions for all prospective employees at different salary levels
2. Consider timing: You might delay retirement plan changes until you have multiple employees to spread fixed costs
3. Explore alternatives: Sometimes paying higher freelancer rates to contractors avoids employee obligations entirely
4. Plan the transition: You have until December 31 to establish most new plans
Use our deduction finder to model different hiring scenarios and see how employee costs impact your total tax savings.
Key takeaway: Hiring employees typically reduces your maximum retirement contribution while adding $2,000-25,000 in annual employee retirement costs, but the right plan choice can minimize the financial impact while maintaining competitive benefits.

Freelancers earning $150K+ who are planning to scale their business with multiple employees and need to understand long-term retirement strategy implications
Strategic retirement planning for scaling businesses
When you're earning $150K+ and planning to hire multiple employees, retirement plan selection becomes a critical business decision that affects both your personal wealth building and your ability to attract top talent.
The high earner's dilemma
As a high-earning freelancer, you likely maximized Solo 401(k) contributions of $40,000-69,000 annually. With employees, your options become more constrained but the tax benefits can still be substantial if structured properly.
Example scaling scenario:
Freelance consultant at $200K planning to hire 3 employees at $75K each over two years.
Year 1 (1 employee):
Year 3 (3 employees):
Advanced strategies for high earners
1. Phased approach: Start with SIMPLE IRA, transition to 401(k) as team grows
2. Contractor vs employee classification: Maintain key contributors as contractors when legally appropriate
3. Defined benefit plans: Consider for stable, high-income businesses with older owners
The key is modeling 3-5 year projections, not just immediate costs.
Key takeaway: High earners should plan retirement strategies around their 3-year hiring roadmap, often starting with SIMPLE IRAs and upgrading to 401(k)s as teams scale beyond 5-10 employees.
Key Takeaway: High-earning freelancers need 3-year retirement planning strategies that account for scaling employee costs, often starting with SIMPLE IRAs and upgrading as teams grow.

Married freelancers who want to hire their spouse and maintain maximum retirement flexibility while staying compliant with family business rules
The spouse exception: Keeping Solo 401(k) benefits
Hiring your spouse is the one exception that allows you to maintain a Solo 401(k) plan. This creates unique opportunities for married freelancers to maximize retirement savings while bringing their spouse into the business.
How spouse hiring works
Under IRS rules, a business owner and their spouse can participate in a Solo 401(k) as long as they have no other employees. This means:
Example: Freelance consultant earning $200K, spouse earning $50K from the business
Requirements for spouse employees
1. Legitimate work: Spouse must perform actual services for reasonable compensation
2. Payroll compliance: Must issue W-2, withhold taxes, file quarterly returns
3. Equal treatment: Cannot discriminate between owner and spouse in plan benefits
When this strategy makes sense
Cost-benefit analysis:
Key takeaway: Hiring your spouse preserves Solo 401(k) eligibility and can enable $100,000+ in annual family retirement contributions while avoiding the costs of employee retirement plans.
Key Takeaway: Married freelancers can hire their spouse to maintain Solo 401(k) benefits and potentially save $100,000+ annually in tax-deferred retirement contributions.
