Which Retirement Plan Is Right for You?

💡 Pro Tip: You Can Combine Strategies
Many savvy business owners use both a qualified plan (like SEP IRA) for immediate tax deductions AND a Maximum Funded IUL for tax-free retirement income. This gives you tax diversification and protection against future tax rate increases.
Key Considerations When Comparing Plans
While SEP IRAs, SIMPLE IRAs, and 401(k)s offer valuable tax deductions today, it's important to understand how each plan handles taxes, distributions, and market risk over time:
⚠️ What All Tax-Deferred Plans Have in Common
- Taxable Withdrawals: Every dollar you withdraw in retirement is taxed as ordinary income. Your effective rate will depend on your total retirement income and future tax policy.
- Required Minimum Distributions: Starting at age 73, you must take distributions whether you need the money or not, which triggers taxable events and can affect Medicare premiums (IRMAA).
- Full Market Exposure: Your retirement savings are subject to market volatility. Diversification and time horizon help manage this risk, but there's no guaranteed floor.
- Tax Rate Uncertainty: Future tax rates are unknown. With TCJA provisions set to sunset and national debt at record levels, many financial professionals believe rates may increase — though this is not certain.
How Maximum Funded IUL Addresses These Considerations
Maximum Funded Indexed Universal Life insurance takes a different approach to each of these areas:
- Tax-Free Access: Policy loans are not taxable income under current IRC §7702 rules — no income tax on distributions
- No RMDs: Keep your money growing for as long as you want — no forced distributions at any age
- 0% Floor Protection: Index crediting won't go negative in down markets, while still participating in market-linked gains
- No Contribution Limits: Fund as much as you want — no IRS caps like qualified plans
- Death Benefit: Your heirs receive a tax-free death benefit in addition to any remaining cash value
ℹ️ IUL Trade-Offs to Consider
- No Immediate Tax Deduction: Unlike SEP IRAs and 401(k)s, IUL premiums are paid with after-tax dollars
- Insurance Costs: IUL includes insurance protection costs — the Maximum Funding strategy is designed to minimize these relative to cash value growth
- Health Qualification: Medical underwriting is required to ensure appropriate coverage
- Professional Guidance: IUL works best when properly designed by an experienced professional
💡 The Strategy Most Business Owners Don't Know
You don't have to choose between a tax deduction now OR tax-free income later. Smart business owners do BOTH: contribute to a SEP IRA for immediate tax savings, and fund a Maximum Funded IUL for tax-free retirement income.
This combination gives you tax diversification—protection against future tax rate increases while maximizing today's deductions.

The best retirement plan depends on your situation. For solo business owners wanting maximum contributions, SEP IRA ($72,000) or Solo 401(k) ($72,000+) are popular. For businesses with employees who want to contribute, SIMPLE IRA or 401(k) work well. For unlimited contributions with tax-free retirement income, Maximum Funded IUL is worth exploring as a complement to qualified plans.
Small business owners can choose from: SEP IRA (up to $72,000, employer-only contributions), SIMPLE IRA (up to $16,500 employee deferrals plus match), Solo 401(k) (up to $72,000+ with catch-up), Traditional 401(k) (for businesses with employees), Defined Benefit Plans (up to $275,000/year), and Maximum Funded IUL (unlimited contributions, tax-free income).
Contribution limits vary by plan type. For 2026: SEP IRA allows $72,000, Solo 401(k) allows $72,000 (plus catch-up contributions), SIMPLE IRA allows $16,500 plus employer match, and Defined Benefit plans can allow $275,000+. Maximum Funded IUL has no contribution limits, allowing unlimited savings.
SEP IRA is the easiest qualified plan to set up—it can be established and funded up to your tax filing deadline, requires minimal paperwork, and has no annual IRS filings. SIMPLE IRA is also relatively easy but must be set up by October 1. Solo 401(k) and traditional 401(k) plans require more administration.
Yes, in some cases. You can have a qualified plan (like SEP IRA) AND a personal Roth IRA. You can also combine a qualified plan with a Maximum Funded IUL for tax diversification. However, you generally cannot have both a SEP IRA and SIMPLE IRA for the same business. Contribution limits across similar plan types may be aggregated.
Among qualified plans, Defined Benefit plans have the highest limits ($275,000+ annually). Among common plans: SEP IRA and Solo 401(k) both allow $72,000 in 2026. However, Maximum Funded IUL has NO contribution limits—you can contribute as much as you want with no caps, making it ideal for high earners who want to save more than qualified plans allow.
