Retirement Plans for Gym Owners and Personal Trainers: How to Shelter $24,500 to $250,000+
Gym owners and personal trainers have no employer-sponsored retirement plan. As self-employed individuals, they must set up and fund their own plans. The advantage is that self-employed retirement plan limits are generous, far exceeding the typical employer 401(k) contribution, and the contributions reduce taxable income. Because fitness is not a specified service trade or business (SSTB), the QBI deduction compounds the tax benefit at all income levels.
Solo personal trainers (no employees other than a spouse) can use a Solo 401(k) ($24,500 employee deferral + up to 20% of SE-adjusted income as an employer contribution for 2026, maximum $72,000 combined, plus catch-up for age 50+) or a SEP IRA (up to 20% of SE-adjusted income, maximum $72,000). The Solo 401(k) is generally better below $300,000 net profit because of the flat-dollar employee deferral. Gym owners with employees (trainers, front desk, cleaning staff) cannot use the Solo 401(k) and must choose a SEP IRA (equal percentage for all), Safe Harbor 401(k) (3% nonelective or 4% match for employees), or SIMPLE IRA ($16,500 employee deferral limit for 2026, lower than the 401(k) limit). Older gym owners (55+) with consistent high income ($200,000+) can add a defined benefit plan allowing contributions of $150,000-$350,000 per year, combined with a 401(k) for maximum tax shelter. The QBI deduction (20% of K-1 income from an S-Corp or net profit from Schedule C) is fully available because fitness is not an SSTB, adding another 4-7% in effective tax savings.
What plan should a solo personal trainer use?
The Solo 401(k) is the best option for a personal trainer with no employees:
The Solo 401(k) also offers a Roth deferral option (contribute after-tax, grow and withdraw tax-free) and a loan provision (borrow up to $50,000 or 50% of balance). The SEP has neither.
What about gym owners with staff?
A gym with trainers, front desk staff, or cleaning personnel cannot use the Solo 401(k). The options are:
SEP IRA: The employer contributes the same percentage for the owner and all eligible employees. At 20% contribution rate, a front desk employee earning $30,000 receives a $6,000 SEP contribution. The equal-percentage requirement makes the SEP expensive for gyms with many lower-paid employees.
Safe Harbor 401(k): The employer makes a 3% nonelective contribution for all eligible employees ($900 per employee at $30,000 salary). Employees can defer up to $24,500 of their own salary (2026). The gym owner defers $24,500 plus receives the employer contribution. This is much less expensive than the SEP’s equal-percentage approach.
SIMPLE IRA: The employer matches up to 3% of salary or makes a 2% nonelective contribution. Employee deferral limit is $16,500 (2026), lower than the 401(k) limit. Simpler to administer than a 401(k) but limits the owner’s contributions.
Defined Benefit + 401(k): For gym owners over 55 earning $200,000+, a defined benefit plan allows contributions of $150,000-$350,000/year. Pairing a DB plan with a 401(k) maximizes the total shelter. The DB plan requires consistent annual funding and annual actuarial costs ($2,000-$5,000/year).
How does the S-Corp interact with retirement contributions?
For an S-Corp gym owner, retirement contributions are based on W-2 salary (not distributions). The employer contribution is 25% of W-2 salary. This creates the salary-optimization dynamic: the salary must be high enough to support the desired retirement contribution but low enough to maintain payroll tax savings.
Because fitness is not an SSTB, the QBI deduction on K-1 income is fully available at all income levels. A lower salary increases K-1 income and the QBI deduction. The optimal salary balances three factors: payroll tax savings, retirement contribution capacity, and QBI deduction.

What are the catch-up contribution rules for business owners over 50?
Business owners aged 50 and older can make additional catch-up contributions beyond the standard limits for most qualified retirement plans. For 401(k) plans including solo 401(k)s, the catch-up contribution is an additional $7,500 for 2025 on top of the standard $23,500 employee deferral limit. SEP IRAs don’t have catch-up provisions because contributions are employer-only and already allow up to 25% of compensation or $70,000. SIMPLE IRAs permit a $3,500 catch-up for those 50 and older, and starting in 2025, participants aged 60-63 get an enhanced catch-up of $5,000 under the SECURE 2.0 Act.
