Cash Balance Plans: The Best-Kept Secret for High-Income Owners
How profitable business owners shelter $150K-$280K+ per year on top of a 401(k)
Quick answer
A Cash Balance plan is a pension that lets a high-income business owner shelter $150,000 to $280,000 or more a year from taxes, on top of a 401(k). It fits owners 45 and older with steady profit over $250,000 and few employees. The plan must be set up by December 31 of the tax year.
Most business owners know about Solo 401(k)s. Some know about SEP IRAs. Very few know about Cash Balance plans — the retirement structure that lets high-income owners shelter $150K-$280K+ per year on top of a 401(k). For the right profile, it's the single most powerful tax strategy in the code.
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
Frequently asked questions
What is a Cash Balance plan?
A Cash Balance plan is a defined benefit pension that is structured to look like a 401(k) account. The IRS treats it as a pension, but you see a personal account balance. Paired with a 401(k), it sharply increases how much a business owner can set aside tax-deferred each year.
How much can I contribute to a Cash Balance plan?
Contributions scale with age — the older you are, the more you can shelter. Rough yearly limits are about $90,000 at age 40, $175,000 at age 50, $240,000 at age 55, and $280,000 at age 60, plus a 401(k) on top.
Who is a Cash Balance plan right for?
It fits business owners 45 and older who want to catch up on retirement savings, have steady profit over $250,000, have few employees or just an owner and spouse, and are comfortable funding the plan for at least five years.
How much does a Cash Balance plan cost to run?
Setup runs about $2,000 to $5,000 one-time, and administration runs about $2,000 to $5,000 a year for the TPA and actuary. For high-income owners the tax savings dwarf the cost — a $200,000 contribution at a 35% rate saves about $70,000, roughly a 17-to-1 return on the admin cost.
When do I have to set up a Cash Balance plan?
The plan must be in place by December 31 of the tax year, though you can fund it through the tax filing deadline. Once set up, you generally need to fund it every year for at least three years, so it is not as flexible as a SEP IRA.
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.
