Cash Balance Plans: The Best-Kept Secret for High-Income Owners

What a Cash Balance plan actually is

A Cash Balance plan is a Defined Benefit pension plan that's structured to look like a Defined Contribution account. The IRS sees it as DB; the participants see it as a 401(k)-like account. Combined with a Solo 401(k) or traditional 401(k), it dramatically increases tax-deferred shelter.

How much you can contribute

Cash Balance contributions scale with age (the older you are, the more you can shelter). 2025 approximate limits:

• ·Age 40: roughly $90,000/year
• ·Age 50: roughly $175,000/year
• ·Age 55: roughly $240,000/year
• ·Age 60: roughly $280,000/year
• ·Plus a 401(k) on top: $70,000 employee + employer

Who Cash Balance plans fit

• ·Business owners 45+ who want to catch up on retirement savings
• ·Profit consistently $250K+ (Cash Balance requires annual funding — can't skip years)
• ·Few employees (or owner + spouse — fewer participants = more goes to owners)
• ·OK with a 5+ year commitment (cash balance plans are designed for long-term, not annual flexibility)

What it costs

• ·Plan setup: $2,000-$5,000 one-time
• ·Annual administration: $2,000-$5,000/year (TPA + actuary)
• ·For high-income owners, the tax savings dwarf the cost
• ·Example: $200K Cash Balance contribution at 35% effective tax rate = $70K of tax savings. $4K admin = 17:1 return on admin cost

The 'stacked' strategy

The real magic happens when you combine a Cash Balance plan with a 401(k). Total tax-deferred shelter for a high-income owner:

• ·Cash Balance plan: $150K-$280K depending on age
• ·Solo 401(k) employee deferral: $23,500 (or $31,000 if 50+)
• ·Solo 401(k) employer profit sharing: ~$46,500
• ·Total possible: $220K-$355K+ per year tax-deferred

Things to know before setting one up

• ·Plan must be in place by Dec 31 of the tax year (can fund through tax filing deadline)
• ·Once established, you generally need to fund annually for 3+ years — not flexible like a SEP
• ·Plan needs an actuary every year — not a DIY structure
• ·Best paired with a CPA who understands DB/cash balance plans (not all do)
• ·Investments typically need to target a specific actuarial return rate (~5%) — not pure growth allocation

When NOT to use a Cash Balance plan

• ·Profit is volatile or under $200K — required funding becomes burdensome
• ·You have many employees (must benefit them proportionally)
• ·You're under 40 (limits are still lower than 401(k) capacity at younger ages)
• ·You want maximum flexibility year-to-year

The Takeaway

Cash Balance plans are one of the most powerful — and most overlooked — tax strategies for high-income business owners. For the right profile ($250K+ profit, age 45+, stable income, owner-heavy demographics), they shelter six-figure tax bills annually. The complexity is real, but the savings dwarf the admin cost. Worth a 30-minute conversation if you fit the profile.
