IUL is permanent life insurance with index-linked interest crediting, policy expenses, and long-term funding responsibilities.
Key takeaways
- An index crediting floor does not prevent policy charges from reducing value.
- Caps and participation rates can change within contractual limits.
- Illustrated values and future income are not guaranteed.
- Loans, underfunding, and MEC status can change the financial and tax result.

Understand what you are buying
is a form of permanent life insurance. It can provide a death benefit and cash value, with interest credited using a formula linked to an external index. You do not own the stocks in that index through the policy. IUL is not a stock market investment.
Start with the insurance need. Who requires the death benefit, how long is the need expected to last, and what payment can the household maintain? Cash value projections should follow those questions. A proposal that begins and ends with an attractive retirement-income number leaves too much unexplained.
A , or life insurance retirement plan, is a strategy built on permanent life insurance. It is not a separate insurance product or an IRS term. An IUL may be used in such a strategy, but the label does not create special government approval, a guaranteed return, or unconditional tax-free income.
Cap, floor, and participation rate
The cap limits the interest credit for an index segment. The participation rate determines the portion of index movement used in the formula. The floor is the minimum index credit under that formula. Other features, such as spreads, bonuses, or index charges, can complicate the calculation.
Consider a simplified hypothetical account with a 0% floor, an 8% cap, and an 80% participation rate. If the measured index rises 10%, multiplying by 80% produces 8%, so the credit is 8%. If the index rises 15%, the preliminary result is 12%, but the cap limits the credit to 8%. If the index falls 10%, the floor produces a 0% index credit.
| Hypothetical index change | After 80% participation | Credit after 8% cap and 0% floor |
|---|---|---|
| 5% | 4% | 4% |
| 10% | 8% | 8% |
| 15% | 12% | 8% |
| -10% | -8% | 0% |
This example ignores charges, timing differences, and other product features. It is not a quote or illustration of an available policy. A 0% floor does not prevent insurance and administrative charges from reducing cash value. Securian’s IUL explanation describes index-based crediting and the possibility of changing caps and participation rates.
Caps can change while the policy is in force, subject to contractual limits. Ask which elements are guaranteed, which can change, and how segment renewals work. Past index performance does not predict future crediting. Even the same index result can produce different policy credits under different contract settings.
Funding is a long-term commitment
A cash-value strategy is long-term, often 10 to 20 years or longer. Early policy charges and surrender charges can be significant. Request a year-by-year schedule showing premiums paid, account value, cash surrender value, death benefit, and charges.
Keep emergency funds and money for near-term goals outside the policy. If you expect to need the premium dollars soon, the timing may not fit. Ask how the plan behaves if you miss a year of funding, reduce contributions, or need to surrender during an expensive period of life.
A flexible premium is not permission to ignore funding. Lower interest credits, increasing insurance costs, or withdrawals can create a need for additional payments. Review the contract’s guarantees and obtain updated illustrations rather than relying indefinitely on the original sales document.
MEC limits and policy access
Funding beyond applicable IRS limits can cause a policy to become a , or MEC. The seven-pay test is defined in Internal Revenue Code section 7702A. MEC status changes the tax treatment of distributions and removes the usual tax-favored treatment of policy loans.
Under the MEC rules, loans can be treated as distributions, with taxable income considered before basis; additional tax may apply depending on age and exceptions. See Internal Revenue Code section 72. Have the insurer confirm allowable funding before an extra payment, benefit reduction, or other material change.
Loans and withdrawals reduce cash value and the death benefit. Loans also accrue interest. Heavy policy borrowing can cause a lapse, and a lapse with gain can create a tax bill even when little or no cash is received at that moment. “Tax-free income” is therefore an incomplete description of a strategy that depends on ongoing policy management.
Read illustrations as scenarios
Illustrations are not guaranteed. Ask for guaranteed values and several conservative non-guaranteed scenarios, including lower credits, reduced caps, missed premiums, and loan interest exceeding credited interest. Examine whether coverage survives and how much additional funding would be required.
Do not judge the plan only by its largest illustrated cash value. Compare the annual premium commitment, surrender restrictions, death-benefit need, and the consequences of abandoning the strategy. Also compare other ways to fund retirement and maintain liquid savings.
Guarantees depend on the claims-paying ability of the issuing insurer. Review that insurer’s financial strength and the exact legal entity issuing the policy. Products and riders vary by state. This article is educational, not tax or legal advice; personal tax and legal questions belong with qualified advisers who can review the actual contract and circumstances.
Frequently asked questions
Can an IUL lose cash value in a year with a 0% floor?
Yes. The floor concerns the index crediting formula. Policy charges, loan interest, and withdrawals can still reduce value. Ask for an illustration showing a zero-credit year after all relevant deductions.
Does an 8% cap mean I earn 8% each year?
No. It is a ceiling in the simplified example, not a promised return. The index result, participation rate, timing, other terms, and charges determine the outcome. Actual caps also may change under the contract.
Is a LIRP an IRS retirement account?
No. It is a planning label for using permanent insurance in a retirement strategy. It does not replace the legal definitions, contribution rules, or protections of an IRA or employer retirement plan.
Can I stop paying once loans begin?
Do not assume so. The policy must continue meeting its funding and coverage requirements. Request an updated illustration showing the planned loans and payments, and review the results regularly as actual experience develops.
Who should review the tax assumptions?
A qualified tax adviser should examine basis, MEC status, proposed distributions, and possible lapse or surrender consequences. The insurer can provide policy records and calculations, but a general marketing illustration is not individualized tax advice.
