Qualified Retirement Plans
Strategy beyond the basics — 401(k), pensions, excess plans, Roth, solo 401(k), cash balance, and more.

401(k) plans
Qualified cash-or-deferred arrangements remain the default wealth engine for employees. Key 2025 reference points include employee deferral limits, catch-up paths (including SECURE 2.0 “super” catch-up ages), and the overall Section 415 limit that caps total annual additions.
- Traditional and Roth elective deferrals, employer match, and profit sharing within one integrated limit
- Plan menu design, auto-enrollment, auto-escalation, and QDIA structure
- Nondiscrimination testing (ADP/ACP) and top-heavy rules that constrain highly compensated employees when rank-and-file deferrals lag
- After-tax contributions plus in-plan Roth conversions (“mega backdoor”) when the plan allows
Common failure modes: matches set at statutory minimums instead of competitive targets; default deferrals stuck at 3% without escalation; weak investment lineups; testing failures that cap HCE deferrals.
Pension and defined benefit plans
Traditional pensions shift investment risk to the employer and provide formula-based benefits. They remain powerful where maintained, but freezes, lump-sum windows, and derisking transfers have reshaped the landscape.
- Actuarial funding, PBGC coverage (private sector), and benefit formula design
- Funding shortfalls and restrictions when funded status falls below key thresholds
- Interaction with Social Security (permitted disparity) and executive “restoration” needs
Excess and non-qualified plans
When IRC limits cap qualified benefits, SERPs, top-hat NQDC, and excess 401(k) arrangements restore flexibility for owners and key employees — at the cost of unsecured promises and strict Section 409A operational rules.
| Arrangement | Role | Notes |
|---|---|---|
| Excess 401(k) | Deferrals above 402(g) or 415 | Ordinary income at distribution; creditor exposure |
| SERP / excess pension | Benefits above 415(b) or pay cap | Employer deduction timing; 409A triggers |
| Top-hat NQDC | Broad executive deferral | Election timing and payment events are heavily regulated |
Roth options inside qualified plans
Roth elective deferrals, in-plan Roth conversions, and after-tax buckets can move tax risk to today while clearing future RMD friction — especially valuable when tax brackets are temporarily low.
- Roth 401(k) shares the same deferral limit as pre-tax; SECURE 2.0 aligned Roth 401(k) RMD treatment with policy intent
- Mega backdoor Roth: after-tax contributions to 415 cap plus in-plan Roth conversion or rollover to Roth IRA when permitted
- Pairing Roth deferrals with taxable brokerage and IRA strategies for layered tax diversification
Solo 401(k) for self-employed owners
Owner-only businesses can often stack employee deferrals with profit sharing up to the Section 415 cap, with streamlined administration until asset thresholds trigger Form 5500 filing.
- Coordination with other 401(k)s when the owner also has a day-job plan
- Roth vs. traditional election, loan features, and custom investment menus
- Pairing with a cash balance plan for materially higher deductible contributions when cash flow supports it
Cash balance and “combo” designs
Hybrid DB/DC designs can accelerate deductions for profitable practices and closely held businesses while managing IRS minimum funding pressure. They require actuarial discipline and clear ownership cash-flow planning.
Overfunded and frozen plans
Surplus assets, reversion risk, and 415 restoration issues require specialized counsel. If your business carries legacy frozen DB liabilities, proactive remediation beats crisis management.
