A policy loan is money the insurer advances to the owner of an indexed universal life (IUL) policy, secured by the policy's own cash value, rather than a withdrawal of the cash value itself.
How a policy loan is structured
When you take a policy loan, the insurer does not hand you your own cash value back. It advances you money from its general account and holds your cash value as collateral, charging loan interest on the balance. Because it is legally a loan and not a withdrawal, it is not treated as taxable income while the policy stays in force and is not a modified endowment contract, and you can generally take it without underwriting or a credit check.
Fixed loans vs. participating loans
Most IUL contracts offer at least one loan type. A fixed loan moves the collateral amount into a separate account that credits a set rate, and the loan itself charges a related fixed rate, so the net cost to you can be small. A participating loan, sometimes called an indexed loan, leaves the collateral inside the index strategy, where it keeps earning whatever that segment credits, while the loan balance separately accrues interest owed. That structure can help you if the index outperforms the loan rate, and hurt you if it does not, since you owe loan interest regardless of what the index does that year.
The lapse tax trap
An unpaid policy loan does not sit still. Interest keeps accruing on it, and if it is never repaid, that growing balance eats into the policy's remaining net cash value year after year. If the balance eventually consumes what is left and the policy lapses, or if you surrender the policy with a loan outstanding, the IRS treats the loan as if it were distributed to you. Any amount of that "distribution" above your cost basis is taxable ordinary income in the year of the lapse, even though you receive no cash at all: the cash value that secured the loan is used to pay it off as the policy terminates. In Sawyer v. Commissioner, T.C. Memo. 2026-33 (April 2026), the U.S. Tax Court applied this rule to a taxpayer whose insurer terminated his policy once his loans exceeded its cash surrender value. He received no cash, but the court treated the value applied to his loans as if it had been paid to him and he had repaid the loans, a taxable deemed distribution of about $160,900 above his investment in the contract.
A hypothetical illustrates the size of the risk: a policy with a $40,000 cost basis lapses when its $90,000 outstanding loan has used up its $90,000 cash value. The $50,000 difference becomes taxable ordinary income that year, with no cash from the policy available to pay the tax bill.
Why this shapes how loans should be managed
Because the trap only triggers at lapse or surrender, monitoring loan balance against cash value, and paying interest out of pocket when needed, keeps the policy from ever reaching that point.
In short: a policy loan is tax-free debt against your own cash value, not tax-free income. That treatment holds only while the policy stays in force and is not a MEC; letting an unpaid loan drive the policy to lapse can turn years of tax-deferred growth into a single taxable event.
Frequently asked questions
Is a policy loan from an IUL taxable?
Generally no, as long as the policy stays in force and was never classified as a modified endowment contract. The loan is debt, not a distribution, so there is nothing to report while the policy remains active.
What is the difference between a fixed loan and a participating loan?
On a fixed loan, the amount you borrow is moved to a separate account crediting a set interest rate, and the loan charges a related fixed rate, sometimes netting close to zero cost. On a participating (or indexed) loan, the borrowed amount stays in the index strategy and keeps earning index credit, while the loan itself accrues interest separately, which can work for or against you depending on index performance.
What happens to a policy loan if I never pay it back?
The unpaid balance and its accruing interest keep reducing the policy's net cash value. If that balance ever grows large enough to exhaust the remaining cash value, the policy can lapse, and the outstanding loan can then trigger a taxable event even though you never received the money as cash.
