The Complicated Tax Rules That Can Either Make or Break Your Indexed Universal Life Strategy Completely

Key Takeaways

• Indexed Universal Life (IUL) policies offer flexible tax advantages, but the rules surrounding them are complex and can significantly impact your retirement outcomes if not carefully managed.

• Proper handling of policy loans, withdrawals, and premiums is essential to prevent unexpected taxes that can reduce the long-term value of your IUL strategy.

Looking Beyond the Surface of IUL Taxation

When you explore Indexed Universal Life (IUL) insurance as part of your retirement strategy, the tax treatment often looks appealing at first glance. Growth inside the policy accumulates on a tax-deferred basis, and with proper structuring, withdrawals and loans can provide tax-free access to cash value. However, the way the Internal Revenue Code regulates these benefits in 2025 makes it critical to understand the fine print. Tax rules can either enhance your policy’s usefulness or erode its effectiveness if you misstep.

Tax-Deferred Growth Inside an IUL

The foundation of an IUL policy’s tax advantage lies in tax-deferred growth. As long as your funds remain within the policy, you do not pay income tax on annual gains. This feature allows your cash value to compound over time without erosion from yearly taxation, similar to qualified retirement accounts. The difference is that IULs do not impose the same contribution limits or mandatory distribution rules.

Still, tax-deferred does not mean tax-free. Eventually, how and when you take money out will determine whether the IRS will require payment.

The Role of Modified Endowment Contracts (MECs)

A key risk that policyholders often overlook is the Modified Endowment Contract (MEC) classification. If your IUL is overfunded beyond IRS limits, it can cross into MEC status. Once that happens, the tax treatment of withdrawals and loans changes dramatically:

• Pre-MEC: Withdrawals are taxed on a first-in, first-out basis, meaning your contributions come out first and are not taxed until you withdraw gains.

• Post-MEC: Distributions are taxed on a last-in, first-out basis. Gains come out first and are taxable as ordinary income.

• Loans: Once classified as a MEC, policy loans lose their tax-advantaged status and become taxable.

The 7-pay test is used to determine MEC status. Exceeding the annual contribution limits for the first seven years is the most common way a policy becomes a MEC. This test continues to apply whenever material changes are made to the contract.

Loans as a Tax-Free Strategy

Policy loans are often marketed as a tax-free way to access IUL cash value. In practice, loans can remain non-taxable, provided the policy is kept in force until death. At that point, the death benefit (reduced by any outstanding loan balance) passes to beneficiaries tax-free under current U.S. tax law.

However, this strategy depends heavily on careful management:

• If the policy lapses while a loan is outstanding, the IRS treats the loan balance as a taxable distribution.

• Large loans can also increase the risk of lapse by reducing available cash value to cover ongoing policy charges.

• Interest accrues on policy loans, and while this is often offset by continued crediting inside the policy, failure to monitor the balance can cause unexpected tax consequences.

Withdrawals and Their Tax Treatment

Withdrawals from an IUL follow different rules than loans. Generally:

• Cost basis first: Withdrawals up to the amount of premiums paid are tax-free.

• Gains second: Withdrawals above the cost basis are taxable as ordinary income.

In retirement, withdrawals may work well in combination with loans, but exceeding your cost basis too early can generate taxable income before you expect it.

Premium Payments and Timing

How you fund your IUL policy has direct tax implications. Overfunding can trigger MEC rules, while underfunding can cause the policy to collapse. Striking the right balance requires:

• Staying within IRS contribution limits under the 7-pay test.

• Funding early in the policy’s life to maximize compounding benefits.

• Monitoring changes in premiums or death benefit amounts, since material changes restart the 7-pay test.

Policy Lapse and Tax Exposure

One of the most damaging outcomes for policyholders is a policy lapse with outstanding loans. In that case, the IRS considers the loan balance taxable income. For example:

• If you have taken significant loans from your IUL and the policy terminates because charges exceed cash value, the loan amount becomes fully taxable in the year of lapse.

This scenario often creates a large, unexpected tax bill in retirement, undermining the intended benefits of the strategy.

Estate and Death Benefit Taxation

While life insurance death benefits generally pass to beneficiaries free from federal income tax, they may still be included in the taxable estate if you own the policy. As of 2025, the federal estate tax exemption remains high, but future legislation could reduce it. Planning ownership of the policy within a trust or through other strategies can help mitigate estate tax exposure.

Coordinating IUL with Other Retirement Accounts

Your IUL policy does not exist in isolation. To avoid excessive taxation, coordinate its use with other accounts:

• Use IUL distributions in years when other taxable income is lower, helping manage overall tax brackets.

• Balance withdrawals with Roth IRA or traditional IRA distributions to create a tax-efficient income stream.

• Consider sequencing distributions to keep Medicare premiums and Social Security taxation thresholds under control.

Potential Legislative Changes

Tax laws governing IUL policies are not guaranteed to remain stable. Congress has adjusted contribution limits, estate tax exemptions, and retirement account rules multiple times over the past decades. Future changes could:

• Alter MEC definitions or thresholds.

• Adjust tax treatment of policy loans or death benefits.

• Change estate tax exemptions, making ownership structures more important.

Planning ahead requires monitoring legislation and updating your strategy as rules shift.

Steps to Keep Your IUL Tax-Advantaged

To safeguard your IUL’s role in retirement:

1. Avoid MEC status by tracking contributions against IRS thresholds.

2. Monitor loan balances to prevent lapses that trigger taxation.

3. Withdraw within basis before accessing gains.

4. Fund strategically early in the policy life to maximize compounding.

5. Review ownership structures to reduce estate tax risks.

6. Coordinate with other retirement vehicles for broader tax efficiency.

7. Stay current on tax law changes to adjust when necessary.

Protecting Your Retirement Vision

An Indexed Universal Life policy can serve as a powerful safe investment tool in your retirement plan, but only if you respect the tax rules that shape its performance. The same features that make IULs attractive—flexibility, tax-deferred growth, and loan-based income—can become vulnerabilities if mismanaged. That is why careful monitoring and regular adjustments are essential.
