Plan for the tax bill, not just the balance

The three buckets and why the mix matters

Taxable

Brokerage accounts and cash. Flexible and fully liquid, taxed on gains and income as they occur.

Tax deferred

401(k), 403(b), traditional IRA. Deduction today, ordinary income tax later, plus required minimum distributions that force withdrawals whether or not you need the money.

Tax advantaged

Roth accounts and, for some people, properly structured cash value life insurance. Funded with after-tax dollars, with the potential for tax-favored access later under current law.

The goal is not to declare one bucket best. It is to avoid having only one.

Where Indexed Universal Life may fit

Indexed Universal Life is a permanent life insurance policy whose cash value is credited based in part on the movement of a market index, subject to a floor and a cap or participation rate set by the carrier. The floor is designed to limit losses in negative index years; the cap limits participation in strong ones.

For a household that has already used available qualified plan space and wants an additional bucket with different tax and market characteristics, a properly designed IUL is one option worth understanding. For a household that has not yet captured an employer match, it usually is not.

• Cash value growth is generally tax deferred under current law
• Access is generally taken through policy loans and withdrawals, which can be tax-favored while the policy remains in force and properly structured
• No income phase-outs and no contribution limits of the kind that apply to IRAs, though funding is constrained by IRS definitional limits for life insurance
• A death benefit that generally passes to beneficiaries income-tax free
• Costs of insurance, policy charges, caps and participation rates are set by the carrier and can change over time

IUL is a life insurance contract, not an investment in the market. It does not pay dividends of an index and it does not participate directly in index gains.

How index crediting actually works

This is the part that gets described loosely, so here is the mechanism. The carrier does not invest your cash value in the index. It holds the bulk of the premium in its general account to support the guarantee, and uses a smaller portion to buy options on the index. What those options return determines the credit.

The floor

Typically 0%, meaning a negative index year credits nothing rather than a loss. Policy charges still apply during that year, so cash value can still decline even when the credit is zero. A 0% floor is not the same as a 0% year.

The cap

The maximum credited in a period. If the cap is 9% and the index returns 20%, you are credited 9%. Caps are set by the carrier, are not guaranteed for the life of the policy, and move with the cost of the options the carrier is buying.

Participation rate and spread

Some designs credit a percentage of index movement instead of, or alongside, a cap, and some subtract a spread before crediting. Read which combination applies before comparing two products by their cap alone.

The crediting period and reset

Most designs measure annually from a starting point that resets each year. The reset is why a recovery year can credit fully after a down year — and also why a mid-year peak you never captured does not count.

Dividends of the index are not included

Index crediting generally tracks price movement only. Over long periods, dividends have been a meaningful share of total index return. Any comparison to "the market" that ignores this is not a fair comparison.

None of this makes IUL good or bad. It makes it a specific instrument with specific behaviour, which is the only basis on which anyone should decide about it.

The risks that deserve equal airtime

• Illustrations are projections, not promises. Ask to see the guaranteed columns, not only the illustrated ones.
• Underfunding a permanent policy is the most common way these strategies fail. Design and funding discipline matter more than the index chosen.
• Policy charges reduce cash value, particularly in early years and at older ages.
• Caps, participation rates and crediting methods can be changed by the carrier within contractual limits.
• Tax treatment depends on current law and on the policy not becoming a modified endowment contract.

Sequence of returns is the risk people underestimate

Two retirees can average the same annual return over thirty years and end up in very different places, purely based on the order those returns arrive. A significant loss in the first few years of drawing income does damage that later gains may not repair, because withdrawals are being taken from a shrinking base.

Having a non-correlated bucket to draw from during down years is one way people attempt to manage this. Whether that is appropriate for you depends on your income needs, other assets, time horizon and risk tolerance.
