Indexed Universal Life Insurance (IUL): What Expats Need to Know

An IUL policy credits the cash-value account with interest based on the gain of a chosen index over a specified crediting period, commonly annual point-to-point. A cap rate limits the maximum credit in any period regardless of how high the index rises. A participation rate sets the fraction of the index gain that is credited. A floor rate, commonly 0%, means the cash value is not reduced by index losses in that period. The floor is a feature of the interest-crediting formula, not a protection against all forms of value reduction: ongoing charges including the cost of insurance continue to be deducted from cash value regardless of index performance. A crediting year at 0% in which charges exceed any credited interest still reduces the policy's cash value. The insurer can lower the cap rate and change the participation rate at its discretion on existing policies. These potential future modifications are not reflected in policy illustrations.

IUL contracts carry a layered fee structure. The cost of insurance (COI) is deducted monthly from cash value; it rises with the policyholder's age and becomes the dominant drain on cash value in later decades. Premium expense charges are deducted from each premium before crediting. Administrative and policy fees are fixed monthly or annual charges. Surrender charges are imposed if the policy is surrendered within the surrender-charge period, commonly ten to fifteen years, and can consume a significant portion of accumulated cash value in the early years. Optional rider charges are deducted for any benefits beyond the base contract. The layered structure makes the true cost of an IUL difficult to assess from a policy illustration alone. The NAIC introduced Actuarial Guideline 49 (AG49) in 2016, revised to AG49-A in 2020 and AG49-B in 2023, specifically to constrain inflated illustration assumptions in IUL sales. Despite these reforms, illustrations still use constant assumed crediting rates that do not reflect year-by-year market volatility, and caps, spreads, and participation rates can be reduced after policy issue in ways that are not shown in any illustration.

Lapse risk is a documented structural concern. If insufficient premiums are paid, or if index credits are lower than projected, or if COI charges accelerate faster than cash-value growth, the policy's cash value can be exhausted by charges. When cash value reaches zero the policy lapses. A lapse terminates the death benefit. For US persons, if a policy loan is outstanding at the time of lapse, the IRS generally treats the full loan amount as a taxable distribution in the year of lapse, potentially producing a significant and unexpected income tax liability. Policyholders who fund only the minimum premium shown on an illustration may face a lapse in later decades when COI charges increase substantially with age.

The US tax framework governing IUL is defined by IRC Section 7702 and IRC Section 7702A. Section 7702 sets out the tests a life-insurance contract must meet for its death benefit to be excluded from the beneficiary's gross income under IRC Section 101(a) and for cash-value growth to be deferred from current US income tax while it remains inside the contract. These rules apply to US domestic tax law. Section 7702A defines the Modified Endowment Contract: a contract that received cumulative premiums in the first seven policy years above the seven-pay limit becomes a MEC. A MEC retains its death benefit but distributions, including loans, are taxed as ordinary income on a last-in, first-out basis, and a 10% additional tax applies to taxable distributions before age 59½. MEC status is permanent and irrevocable. These US tax provisions apply to US persons under US domestic law. Non-US persons receive no automatic US tax benefit from holding an IUL policy; the tax treatment of distributions and death benefits in the policyholder's country of residence is governed by that country's law, and requires separate analysis by a cross-border tax specialist.
