Cash Balance plan vs. 401(k): which fits your business?
Both are qualified retirement plans. The choice usually comes down to age, free cash flow, employee demographics, and how aggressively you want to accelerate tax-deductible retirement savings.
| Feature | Cash Balance Plan | 401(k) + Profit Sharing |
|---|---|---|
| Plan type | Defined benefit (hybrid) | Defined contribution |
| 2025 owner contribution (age 50) | ~$170,000+ (age-weighted) | $77,500 ($23,500 + $7,500 catch-up + employer) |
| 2025 owner contribution (age 60) | ~$280,000+ (age-weighted) | $81,250 (with §414(v) higher catch-up) |
| Age weighting | Strongly favors older owners | Equal % of pay |
| Annual funding | Required (actuarial) | Discretionary |
| Investment risk | Plan sponsor (employer) | Participant |
| Required staff cost | Typically 5–7.5% of staff pay | Typically 3% safe harbor + match |
| Setup complexity | Higher (actuary required) | Lower (TPA managed) |
| Best fit | Owners 45+, stable cash flow | Any size, variable cash flow |
| Can be combined? | Yes — usually paired with 401(k) | Yes — usually paired with CB |
Common questions about this comparison
Can I have both a Cash Balance plan and a 401(k)?
Yes — and most owners using a Cash Balance plan also keep a profit-sharing 401(k). Combined, the structures can allow $200,000+ in annual pre-tax contributions for an owner age 50+, depending on plan design and demographics.
Who is a Cash Balance plan a bad fit for?
Owners under age 40 with limited free cash flow, businesses with highly variable income, and owners who do not want the multi-year funding commitment. The plan must be funded annually.
Are Cash Balance contributions guaranteed deductible?
Subject to actuarial limits and IRC §415, yes — and SECURE 2.0 added flexibility. But the contribution must be funded by the deadline and the plan must follow nondiscrimination testing.
What about employees?
A Cash Balance plan typically requires meaningful employer contributions to non-owner staff (often 5–7.5% of pay). Plan design balances owner-deductible dollars against staff cost.
