For top-tier earners—such as medical practice partners, specialized law firm partners, engineering executives, and profitable mid-market business owners—traditional qualified retirement accounts offer inadequate tax sheltering.
Under the Internal Revenue Code (IRC), conventional defined contribution limits restrict standard 401(k) and profit-sharing plans to an annual contribution ceiling ($69,000 to $76,500 with catch-ups). For an entrepreneur or medical specialist earning between $700,000 and $3,000,000 annually, sheltering under $70,000 leaves more than 90% of their earnings fully exposed to top-bracket taxation.
Between the highest marginal federal income tax bracket (37%), the uncapped Medicare tax (including the 0.9% Additional Medicare Tax), and state income tax rates reaching 9% to 13.3%+ in states like California, New York, New Jersey, and Massachusetts, high-earning partners routinely forfeit nearly half of their marginal earnings to current-year tax realization.

Conventional 401(k) / Profit-Sharing Plan Unprotected Marginal Income
• Maximum statutory deferral: ~$69,000 • $931,000 exposed to top tax brackets
• Shields less than 7% of gross earnings • Subject to 37% Federal + 2.35% Medicare
• Tax savings: ~$32,000 • Subject to 10%–13.3% State Income Tax
• CASH LOST TO TAXES: $450,000+ / year
To resolve this limitation without relying on non-qualified deferred compensation arrangements (which remain subject to corporate bankruptcy and creditor risk), high-earning business owners deploy Cash Balance Pension Plans.
Legally classified as an IRS-qualified Defined Benefit Plan, a Cash Balance plan allows business owners to contribute and deduct $150,000 to $350,000+ per partner annually above standard 401(k) limits.
When paired with a Safe Harbor 401(k) and Profit-Sharing “Combo Plan” and validated using actuarial cross-testing under IRC § 401(a)(4), this framework enables business owners to shelter hundreds of thousands of dollars in pre-tax income every year, accumulate multi-million-dollar retirement balances, and legally roll over those assets into self-directed IRAs upon retirement.
1. Defining the Cash Balance Plan: The Hybrid Architecture
To understand how a Cash Balance plan functions, one must examine its hybrid structure: it is legally governed as a Defined Benefit Plan, but operates from the participant’s perspective like a Defined Contribution Plan.
[ THE QUALIFIED RETIREMENT MATRIX ]

┌───────────────────────────────────────┼──────────────────────────────────────┐
▼ ▼ ▼
Defined Contribution Plans Traditional Defined Benefit Plans Cash Balance Pension Plans
(401(k) / Profit-Sharing) (Legacy Corporate Pensions) (Hybrid Qualified Design)
• Account balance driven • Monthly benefit for life at retirement• Hypothetical account balance driven
• Employee/Owner absorbs market risk • Actuarial formula based on tenure/pay • Employer absorbs asset volatility
• Hard statutory cap ($69k–$76k) • Complex, opaque funding formulas • Age-weighted caps ($150k–$350k+)
• Total investment transparency • Opaque to average employees • Absolute statement transparency
The Legal Framework vs. The Participant Experience
- The Regulatory Core: Under IRC § 414(j) and the Employee Retirement Income Security Act (ERISA), a Cash Balance plan is categorized as a Defined Benefit plan. The plan is maintained by the employer, backed by a pooled trust account, and subject to annual actuarial certifications under IRC § 412.
- The Hypothetical Account Balance: Unlike a traditional defined benefit pension that promises a monthly check upon retirement based on a complex final-average-pay formula, a Cash Balance plan tracks participant value using a Hypothetical Account Balance.
- Participant Transparency: Every participant receives an annual statement displaying their exact portfolio balance, similar to a 401(k) portal.
Each participant’s balance grows through two mandatory components:
$$\text{Annual Balance Growth} = \text{Annual Pay Credit} + \text{Annual Interest Credit}$$
- The Pay Credit: A contribution specified in the plan document, formulated either as a flat dollar amount (e.g., $250,000 per partner) or as a percentage of annual compensation (e.g., 25% of gross earnings up to statutory compensation caps).
- The Interest Crediting Rate (ICR): A guaranteed rate of return credited to the hypothetical balance annually, independent of the actual market performance of the underlying trust investments.
2. The Power of the “Combo Plan”: Safe Harbor 401(k) + Profit-Sharing + Cash Balance
A Cash Balance plan is rarely deployed as a standalone vehicle. Instead, wealth architects use a Tri-Tiered “Combo Plan” Architecture that stacks three distinct qualified vehicles together to maximize owner deductions while minimizing staff contribution requirements.
[ THE TRI-TIERED COMBO PLAN ARCHITECTURE ]

┌────────────────────────────────────┼────────────────────────────────────┐
▼ ▼ ▼
Tier 1: Safe Harbor 401(k) Tier 2: Discretionary Profit-Sharing Tier 3: Cash Balance Pension
• Elective deferral: $23,500 • Employer contribution: $46,000 • Actuarially defined pay credit:
• Catch-up (age 50+): $7,500 • Governed by IRC § 404(a)(7) $150,000 to $300,000+
• Funded via personal salary 25% deduction limit carve-out • Governed by IRC § 415(b)
Tier 1: The Safe Harbor 401(k) Deferral
The foundation begins with a standard Safe Harbor 401(k) plan.
- Owner Contribution: The business owner elects to defer the maximum statutory elective deferral ($23,500, plus an additional $7,500 catch-up if age 50 or older) directly from their W-2 salary or partnership earnings.
- The Safe Harbor Shield: By making a non-elective 3% employer contribution to all eligible non-owner employees (or a 4% matching contribution), the plan automatically satisfies mandatory Actual Deferral Percentage (ADP) and Actual Contribution Percentage (ACP) non-discrimination tests under IRC § 401(k)(12). This allows the owners to max out their personal deferrals regardless of how much rank-and-file employees choose to contribute.
Tier 2: The Discretionary Profit-Sharing Carve-Out
Layered directly onto the 401(k) is an employer-funded profit-sharing contribution.
- Owner Contribution: The business credits an additional discretionary profit-sharing payment to the owner’s account (typically up to the statutory limit, capping the 401(k)/Profit-Sharing bucket at $69,000 to $76,500).
- The Combined Plan Deduction Limit (IRC § 404(a)(7)): Under standard rules, when an employer sponsors both a defined contribution plan and a defined benefit plan, total deductible contributions across both plans are capped at 25% of eligible participant payroll.
- The Statutory Carve-Out (PPA 2006): Under amendments enacted in the Pension Protection Act of 2006, employer contributions to a defined contribution plan up to 6% of eligible payroll are completely exempt from the 25% combined deduction cap. This allows the business to fund a 6% profit-sharing contribution for staff while unlocking the full funding capacity of the Cash Balance plan above it.
Tier 3: The Cash Balance Pension Plan Layer
Sitting atop the defined contribution tiers is the Cash Balance plan.
- Owner Contribution: The plan credits an age-weighted pay credit ranging from $150,000 to $300,000+ directly to the owner’s hypothetical account.
- The Combined Deduction: The business deducts 100% of Tier 1, Tier 2, and Tier 3 contributions as an ordinary and necessary business expense under IRC § 404(a)(1).
3. Actuarial Age-Scaling: Why Contribution Caps Increase with Age
Unlike defined contribution plans—where contribution caps are uniform regardless of age (except for modest catch-ups)—Cash Balance plans are governed by the Maximum Defined Benefit Limit under IRC § 415(b).
[ HOW THE IRC § 415(b) ACCELERATOR WORKS ]
Statutory Benchmark:
Under IRC § 415(b), a participant can accumulate an actuarial pension capable
of paying an annual lifetime benefit of up to $275,000 to $280,000+ per year at retirement.
│

Actuarial Calculation:
To fund a maximum lifetime pension by normal retirement age (typically age 62–65),
how much capital must be contributed to the trust each year?
│
┌────────────────────────────────┴────────────────────────────────┐
▼ ▼
A 35-Year-Old Founder Has 30 Years to Fund A 55-Year-Old Partner Has Only 10 Years to Fund
• 30 years of compounding runway • Short 10-year funding window
• Needs smaller annual contributions to reach cap • Must contribute massive annual capital tranches
• Statutory Annual Contribution: ~$80,000–$120,000 • Statutory Annual Contribution: ~$280,000–$350,000+
The Mathematics of Age-Weighted Contributions
Because a defined benefit plan calculates what is required today to fund a target benefit at retirement age, the mathematical formula relies heavily on the time value of money:
$$\text{Annual Required Contribution} = f(\text{Retirement Target}, \text{Years to Retirement}, \text{Assumed Interest Rate})$$
The fewer years a participant has remaining until the plan’s Normal Retirement Age (NRA), the larger the annual contribution required to fund that benefit. Consequently, maximum allowable contributions scale aggressively as an owner ages:
[ 2026 ILLUSTRATIVE ANNUAL CASH BALANCE CONTRIBUTION CAPS ]

─────────────────────────────────────────────────────────────────────────────────────────────────────────────

Age 41 – 45 $160,000 – $195,000 $69,000 $229,000 – $264,000
Age 46 – 50 $205,000 – $240,000 $76,500 (Catch-up added) $281,500 – $316,500
Age 51 – 55 $250,000 – $295,000 $76,500 $326,500 – $371,500
Age 56 – 60 $305,000 – $345,000 $76,500 $381,500 – $421,500
Age 61 – 65+ $350,000 – $400,000+ $76,500 $426,500 – $476,500+
The Lifetime Accumulation Limit
Over an executive’s career, a Cash Balance plan can accumulate between $3.5 million and $4.0+ million in total tax-sheltered capital per partner under current actuarial thresholds. Once a partner hits this cumulative lifetime funding ceiling, the plan ceases contributions for that individual and is typically terminated or rolled over into a self-directed traditional IRA.
4. Cross-Testing and Non-Discrimination: The IRC § 401(a)(4) Gateway
A frequent question raised by business owners with staff is: If I contribute $300,000 for myself, am I legally required to contribute the same percentage (e.g., 50% of salary) for all of my employees?
The answer is an absolute no.
Under the IRS’s Cross-Testing Regulations (Treasury Regulation § 1.401(a)(4)-8), defined contribution and defined benefit plans can be tested together on the basis of equivalent retirement benefits at retirement age, rather than current-year contributions.
[ CROSS-TESTING ARBITRAGE MECHANICS ]
CURRENT YEAR CONTRIBUTIONS (What is deposited today)
• High-Earning Owner (Age 55): Receives $300,000 cash credit (50% of compensation).
• Young Employee (Age 28): Receives $3,500 cash credit (5%–7.5% of compensation).
│
▼
ACTUARIAL PROJECTION TO AGE 65 (The Cross-Testing Translation)
• The young employee's 5% contribution has 37 YEARS to compound in the market.
• The older owner's 50% contribution has ONLY 10 YEARS to compound.
│
▼
IRS NON-DISCRIMINATION DETERMINATION (§ 401(a)(4))
Actuarially, the projected annual retirement benefit of the young employee is EQUAL
TO OR GREATER THAN the projected benefit of the older owner!
THE PLAN PASSES IRS NON-DISCRIMINATION TESTING WITH 85%–90%+ EFFICIENCY!
The Gateway Contribution Test
To utilize cross-testing, the plan must satisfy the statutory Gateway Test under Treasury Regulation § 1.401(a)(4)-8(b)(1):
- The employer must provide a minimum non-elective contribution to all qualifying non-highly compensated employees (NHCEs).
- Typically, providing a 5.0% to 7.5% profit-sharing contribution to rank-and-file staff satisfies the gateway test.
Mathematical Efficiency Analysis
Consider an established medical surgical practice:
[ Medical Practice Census ]
• Partner 1 (Surgeon, Age 56): W-2 Compensation = $350,000
• Partner 2 (Surgeon, Age 52): W-2 Compensation = $350,000

- Owner Share of Contributions:$699,000 (93.5%) goes directly into the owners’ personal retirement accounts.
- Staff Overhead:$48,500 (6.5%) is distributed to employees as a retention incentive.
- Tax Savings Calculus: At a blended 42% state and federal tax bracket, the $747,500 deduction saves the business $313,950 in cash taxes.
- The Bottom Line: The owners spend $48,500 on staff contributions to capture $313,950 in tax savings, generating a net positive cash arbitrage of +$265,450 while funding $699,000 of personal retirement equity.
5. Actuarial Mechanics: Interest Crediting Rates (ICR) and Investment Governance
In a 401(k) plan, the investment performance of the underlying stocks and mutual funds belongs entirely to the employee. If the market rises 20%, the account grows 20%; if the market declines 20%, the account balance drops.
In a Cash Balance plan, the employer bears all investment risk.

[ THE ACTUARIAL RECONCILIATION (ANNUAL AUDIT) ]
• Actual Trust Assets MUST MATCH the Hypothetical Liabilities.
• If trust yields 15% ──► The Plan becomes OVERFUNDED (Traps cash).
• If trust loses -10% ──► The Plan becomes UNDERFUNDED (Forces cash in).
The Role of the Interest Crediting Rate (ICR)
The plan document establishes a fixed formula for the annual Interest Crediting Rate. Under IRS regulations (Treasury Regulation § 1.411(b)(5)-1), common ICR benchmarks include:
- Fixed Rate Option: A static rate between 3.0% and 5.0% (4.0% or 5.0% is standard; the IRS caps fixed ICRs at a maximum of 6.0%).
- Treasury Yield Peg: Pegged to the yield of the 30-Year US Treasury Bond or the 10-Year Treasury Note.
- Actual Rate of Return (ARR): Available under modern statutory rules, where the crediting rate matches the actual net investment return of the trust assets (subject to strict preservation-of-capital rules).
The Danger of Overfunding vs. Underfunding
Because the hypothetical account balance increases by the fixed ICR (e.g., 4%), the actual physical assets in the trust account must track this actuarial trajectory:
1. Underfunding Risk (Market Crash)
If the trust’s investments drop by 15% during a market correction while the plan liabilities grow by 4%, the plan develops an actuarial deficit. Under IRC § 430, the employer is legally obligated to make mandatory, out-of-pocket cash contributions over subsequent plan years to restore statutory funding levels, creating unexpected corporate cash strain.
2. Overfunding Risk (The Trap of High Returns)
If an aggressive trustee invests the Cash Balance funds into high-beta tech stocks or private equity generating a 30% return, the trust develops an excessive surplus.
- Because the hypothetical accounts of the participants are only entitled to the contractual 4% ICR, the excess capital cannot be distributed directly to owners.
- The Trap: The surplus reduces the business’s allowable tax-deductible contributions in future years. If the plan terminates with an unallocated surplus, recovering that cash incurs a 50% IRS excise tax on reversions under IRC § 4980, alongside ordinary corporate income taxes.
Asset-Liability Matching (ALM) Investment Strategy
To protect against both overfunding and underfunding hazards, experienced Cash Balance trustees avoid speculative equities. Instead, they deploy an Asset-Liability Matching (ALM) strategy:
- Target Portfolio Return: Calibrated to match the plan’s ICR plus administrative expenses:
$$\text{Target Trust Yield} = \text{ICR (e.g., 4.0\%)} + \text{TPA / Custody Expense (0.50\%)} = \mathbf{4.50\%}$$ - Portfolio Construction: Allocations are concentrated in short-to-intermediate high-grade corporate bonds, US Treasury bills, fixed-income ladders, capital-preservation cash sweeps (ICS/CDARS), and short-duration structured notes.
- Core Mandate: The goal of the Cash Balance trust is tax deduction and asset preservation, not speculative capital growth. Alpha is generated on the front end by avoiding a 45%+ tax hit, not by taking high equity beta risk inside the trust.
6. Business Eligibility and Ideal Practice Demographics
A Cash Balance plan is not universally applicable to all business models. It is designed for specific enterprise profiles where profitability is high, cash flow is consistent, and owner-to-employee demographics align.

└───────────────────────────────────────┘ └───────────────────────────────────────┘
Ideal Enterprise Profiles
- Professional Service Partnerships (Medical, Legal, Accounting): Multi-partner practices where partners earn substantial professional income and wish to maximize tax deductions independently of one another. Plans can be drafted with tiered contribution classes, allowing a 60-year-old partner to contribute $300,000 while a 34-year-old junior partner contributes $80,000.
- Solo Entrepreneurs and Independent Consultants: Independent corporate executives, 1099 medical contractors, and boutique software advisors operating as single-member S-Corporations or sole proprietorships with zero non-owner employees. The owner can claim 100% of the tax deduction without spending a single dollar on gateway staff contributions.
- Family-Owned Businesses: Closely held companies where key family members hold executive positions, enabling generational wealth accumulation within an ERISA-protected wrapper.
Unsuitable Enterprise Profiles
- Volatile Early-Stage Startups: Companies with irregular cash flows, fluctuating venture rounds, or uncertain profitability. Cash Balance plans carry statutory annual funding commitments; skipping contributions during lean years creates severe compliance penalties.
- Labor-Intensive, Low-Margin Industries: Large retail operations, restaurants, or hospitality businesses with hundreds of low-wage workers. Even a 5% gateway contribution across a 200-person staff will quickly exceed the tax savings captured by the owners.
7. ERISA Asset Protection and PBGC Regulatory Realities
Beyond tax optimization, Cash Balance pension plans offer two structural protections under federal law: absolute creditor insulation and pension insurance exemptions.

│ • Far superior to state-level IRA protections │ │ ERISA § 4021(b)(13)! │
└───────────────────────────────────────────────┘ └───────────────────────────────────────────────┘
Absolute Creditor Protection (ERISA Anti-Alienation)
For high-liability professionals (such as surgeons, obstetricians, real estate developers, and corporate directors), asset protection is a primary concern:
- The Federal Shield: Under ERISA § 206(d)(1) and IRC § 401(a)(13), qualified retirement plans contain an mandatory Anti-Alienation Clause. Plan assets cannot be assigned, attached, garnished, or seized by civil judgment creditors, bankruptcy trustees, or malpractice litigants.
- The Supreme Court Benchmark (Patterson v. Shumate): In Patterson v. Shumate, 504 U.S. 753 (1992), the US Supreme Court confirmed that ERISA-qualified plan balances are completely excluded from a debtor’s bankruptcy estate.
- Advantage over IRAs: Individual Retirement Accounts (IRAs) are governed by varying state debtor-protection statutes and capped federal bankruptcy exemptions (under the Bankruptcy Abuse Prevention and Consumer Protection Act – BAPCPA). An ERISA Cash Balance plan provides unlimited, uncapped federal asset protection.
The PBGC Exemption for Professional Service Firms
The Pension Benefit Guaranty Corporation (PBGC) is the federal agency that insures private defined benefit plans, assessing annual per-participant premiums and imposing complex administrative filings.
However, under ERISA § 4021(b)(13), Congress enacted an explicit statutory exemption:
- Any plan established and maintained by a Professional Service Employer (physicians, attorneys, dentists, architects, actuaries, engineers) that has at no time after September 2, 1974, had more than 25 active participants is completely exempt from PBGC coverage.
- Operational Benefit: Small medical and legal partnerships save thousands of dollars annually in PBGC premium surcharges and bypass complex federal reporting mandates.
8. Exit Strategies: Plan Termination, Portability, and Rollovers
A Cash Balance plan is not meant to run forever. It is an intentional wealth-accumulation vehicle designed for a three- to ten-year lifecycle. Once owners achieve their target accumulation goals, they execute a planned exit.

(Real estate, private credit, physical gold)
The Permanence Doctrine (Treasury Regulation § 1.401-1(b)(2))
Under federal tax law, an employer cannot establish a Cash Balance plan with the intention of running it for a single year purely as a one-off tax write-off.
- The Rule: The IRS mandates that a qualified plan must be established with the intent of being a “permanent program.”
- The 3-to-5-Year Safe Harbor: In practice, maintaining a plan for at least three to five consecutive years satisfies the IRS permanence doctrine.
- Legitimate Business Necessity Exceptions: A plan can be terminated earlier if the business experiences a legitimate, verifiable business change: the departure or death of a primary partner, partner retirement, an economic downturn, loss of a key commercial contract, or the sale of the business.
The Direct Rollover Protocol (IRC § 402(c))
When the plan terminates:
- Actuarial Closeout: The Third-Party Administrator (TPA) and enrolled actuary issue final benefit distribution packages and file a final IRS Form 5500.
- Trustee-to-Trustee Transfer: Under IRC § 402(c), participants elect to execute a direct qualified rollover. The entire cash balance is wired directly into each participant’s Traditional Individual Retirement Account (IRA) or an existing 401(k) account.
- Tax Neutrality: The transaction triggers zero current-year income taxes and zero early-withdrawal penalties.
- Unlocking Alternative Investments: Once inside a traditional IRA, the capital can be converted into a Self-Directed IRA (SDIRA), unlocking checkbook control to invest in private debt, real estate syndications, private equity, and physical precious metals.

10. Step-by-Step Implementation and Administration Blueprint
Establishing and administering a compliant Cash Balance Pension Plan requires coordinated execution between an enrolled actuary, a specialized Third-Party Administrator (TPA), an investment custodian, and a corporate tax CPA.

▼
[ Phase 6: Lifecycle Plan Termination & IRA Rollover Execution ]
Phase 1: Employee Census and Actuarial Feasibility Study
- Compile Census Data: Collect a three-year trailing payroll schedule covering all business personnel: exact birth dates, hire dates, W-2 compensation, ownership percentages, and family relationships.
- Commission Feasibility Modeling: The enrolled actuary models various contribution classes, testing whether the owner group can capture 85% to 90%+ of total dollars while keeping staff gateway contributions at or below 5% to 7.5%.
Phase 2: Plan Document Customization and Tiered Structuring
- Draft the Master Plan: The TPA drafts a customized plan document under IRC § 401(a), incorporating:
- Specific tiered contribution formulas (e.g., “Group A Partners receive $275,000; Group B Associates receive 3%”).
- The selected Interest Crediting Rate (e.g., Fixed 4.0% or 30-Year Treasury yield).
- Normal retirement age definitions (typically age 62 or 65) and vesting schedules (typically a 3-year cliff vesting schedule, permitted under IRC § 411(a)(13)).
Phase 3: Formal Corporate Adoption Deadlines (The SECURE Act Advantage)
- The Regulatory Shift (SECURE Act): Historically, a qualified retirement plan had to be formally adopted by December 31st of the tax year for which deductions were claimed.
- The Modern Extension: Under the SECURE Act and SECURE 2.0, an employer can adopt a Cash Balance plan up to the due date of the corporate tax return (including extensions) and still claim deductions for the preceding tax year:
- Application: An S-Corporation or Partnership can establish a plan in July or September of Year 2 and apply a $300,000 tax deduction retroactively to Year 1, providing exceptional retrospective tax planning flexibility.
Phase 4: Custodial Account Setup and Investment Calibration
- Open the Trust Account: Establish a dedicated institutional trust account chartered under the formal legal name of the plan at a premier brokerage custodian (Charles Schwab Institutional, Fidelity, Vanguard).
- Implement Asset-Liability Matching (ALM): Allocate trust assets into conservative fixed-income instruments and cash sweeps calibrated to generate the plan’s 4.0% ICR, eliminating speculative equity beta risk.
Phase 5: Annual Actuarial Testing and Tax Filing
- Annual Actuarial Valuation: Following the close of each plan year, the actuary evaluates trust assets against liabilities, issues the formal Actuarial Valuation Report, and establishes the mandatory funding range (Minimum, Recommended, and Maximum allowable deduction).
- File Form 5500 with Schedule SB: The TPA prepares and files IRS Form 5500, accompanied by Schedule SB (Single-Employer Defined Benefit Plan Actuarial Information), signed by an Enrolled Actuary (EA).
- Deliver the Tax Deduction: The business CPA deducts the certified contribution amount directly on the corporate tax return (Form 1120-S, Form 1065, or Schedule C), reducing taxable income dollar-for-dollar.
Strategic Action Checklist for Business Owners and Partners
- Audit Your Taxable Business Earnings: If your business generates consistent net taxable income exceeding $500,000 annually, evaluate a Cash Balance + 401(k) Combo Plan to increase your pre-tax deduction capacity from $69,000 to $350,000+.
- Confirm Demographic Viability: Ensure the business owner group is, on average, older than the non-owner employee base. This age asymmetry is what unlocks the power of IRC § 401(a)(4) cross-testing.
- Insist on Conservative Trust Investments: Avoid chasing high equity returns inside the Cash Balance trust. Align asset allocations directly with the plan’s Interest Crediting Rate (3.5% to 4.5%) using high-grade fixed income to prevent overfunding traps and the 50% IRS excise tax under IRC § 4980.
- Confirm PBGC Exemption Status: If you operate a medical, legal, or architectural practice with fewer than 25 participants, ensure your plan document formally claims the ERISA § 4021(b)(13) exemption, eliminating annual PBGC insurance fees and reporting overhead.
- Utilize the SECURE Act Extension: Remember that you can adopt a Cash Balance plan retroactively up to your extended corporate tax return deadline (September 15th for S-Corps/Partnerships) to offset the previous calendar year’s tax liability.
- Plan for the 5-Year Exit: Treat the plan as an intentional 3-to-5-year wealth accumulation project. Once cumulative contributions approach the IRC § 415(b) lifetime threshold ($3.5M–$4.0M), terminate the plan and roll the assets tax-free into a Self-Directed Traditional IRA.
