Retirement Plans for Coaches: Sheltering Income While Managing the SSTB Threshold
Coaches, whether business coaches, executive coaches, life coaches, or wellness coaches, have the same retirement plan options as any self-employed person. The Solo 401(k) offers the highest contribution limits for solo coaches, and the SEP IRA is simpler for those who want minimal administration. What makes coaching different is the SSTB classification: coaching falls under “consulting” in the IRC 199A regulations, which means the QBI deduction phases out above $191,950 single / $383,900 MFJ. Retirement contributions can push taxable income below the phase-out threshold, serving a dual purpose.
Solo coaches can use a Solo 401(k) ($23,500 deferral + approximately 20% employer contribution for 2025, maximum $70,000 combined, plus catch-up). The Solo 401(k) offers a Roth option and loan provision. A SEP IRA is limited to approximately 20% of net SE income (no flat deferral, producing smaller contributions below $300,000). Because coaching is an SSTB, retirement contributions reduce taxable income, which can pull the coach below the QBI phase-out threshold ($191,950 single / $383,900 MFJ) and preserve the full 20% QBI deduction. A $23,500 Solo 401(k) deferral for a coach at $210,000 taxable income drops taxable income to $186,500, moving from partial QBI to full QBI, saving an additional $3,000-$5,000 in taxes beyond the retirement contribution’s own deduction. For high-income coaches ($300,000+) above the phase-out range, the QBI deduction is zero regardless, and the retirement plan’s purpose simplifies to tax deferral. Older coaches (55+) can add a defined benefit plan ($150,000-$350,000/year) for maximum shelter.
How does the dual purpose work?
What about coaches with group programs and employees?
A coaching business that grows to include associate coaches, program managers, or administrative staff can’t use the Solo 401(k). The plan must cover eligible employees.
The Safe Harbor 401(k) with a 3% employer contribution is the most cost-effective option: $1,200 per employee at $40,000 salary. The coach defers $23,500 and receives the employer contribution, while the employee cost is modest.
For coaches running group programs with contract facilitators (1099 contractors), the contractors aren’t employees of the coaching business. The Solo 401(k) remains available for the coach, and each contractor establishes their own plan.

What happens if I contribute more than the allowed limit to my retirement plan?
Excess contributions are subject to a 6% excise tax each year they remain in the account (IRC 4973 for IRAs, IRC 4979 for 401(k) plans). For IRAs, you can withdraw the excess plus attributable earnings before the tax filing deadline (including extensions) to avoid the penalty for that year. For solo 401(k) plans, excess deferrals must be corrected by April 15 of the following year. Excess employer contributions can be corrected through plan amendment. The contribution limits are aggregate across all plans of the same type, so if you contribute to both an employer 401(k) and a solo 401(k), the employee deferral limit is shared.
What retirement deadlines matter for a coach near the SSTB threshold?
A coach often doesn’t know whether taxable income clears the SSTB threshold until the year closes, so the after-year-end deadlines matter most. SEP and Solo 401(k) employer contributions for 2025 can go in until your return due date with extensions, which is October 15, 2026 for a sole proprietor who files Form 4868.
The employee deferral is tighter. In an existing Solo 401(k) you have to elect it by December 31, though the deposit can wait until the extended due date. A sole proprietor with no employees who opens a new Solo 401(k) after year-end can still make 2025 deferrals, but only until April 15, 2026. Coaches who work through an S corporation don’t get that first-year option, and their SEP or profit-sharing deadline follows the S corp return, due March 16, 2026 for 2025 unless extended.
- A defined benefit plan can be adopted as late as the extended due date and treated as in place for the prior year. Its minimum required contribution is due 8.5 months after the plan year ends.
