IUL vs Roth IRA for tax-free retirement income
Both are marketed as tax-free retirement income. Compare 2026 Roth IRA limits and income phase-outs with IUL loans, costs, access rules and risks.
A Roth IRA and an indexed universal life policy can both deliver retirement money free of income tax, but they are built differently. A Roth IRA is a low-cost investment account with a 2026 contribution limit of $7,500 and income limits. An IUL has no annual contribution cap but carries insurance charges, caps on gains and lapse risk. For most savers, the Roth IRA is the first stop and IUL a possible addition for those with a real life insurance need.
2026 Roth IRA rules
According to the IRS (Notice 2025-67, November 2025), for 2026:
| Item | 2026 |
|---|---|
| IRA contribution limit | $7,500 |
| IRA catch-up, age 50 and over | $1,100 |
| Roth income phase-out, single or head of household | $153,000 to $168,000 (modified AGI) |
| Roth income phase-out, married filing jointly | $242,000 to $252,000 |
The limit applies to all your IRAs combined and requires earned income at least equal to the contribution. Above the phase-out range, you cannot contribute directly to a Roth IRA. Some higher earners use a "backdoor" conversion; the tax treatment depends on other IRA balances, so ask a tax professional.
Roth IRA contributions (not earnings) can be withdrawn at any time without tax or penalty. Earnings are tax-free when the distribution is qualified: generally after age 59 1/2 and after the account has been open five years. A Roth IRA has no required minimum distributions during the owner's life.
How IUL "tax-free income" works
An IUL is funded with after-tax premiums. Cash value grows tax-deferred. Money comes out in three ways, covered in how cash value is taxed: withdrawals, loans and surrenders:
- Withdrawals up to the amount of premiums paid (your basis) are generally tax-free, but reduce the cash value and the death benefit.
- Policy loans are generally not taxable income when the policy is not a modified endowment contracts and the 7-pay test, because they are loans. Interest accrues, and the loan is repaid from the death benefit if unpaid.
- Surrender is taxable to the extent proceeds exceed basis.
The "tax-free" claim therefore depends on keeping the policy in force until death. If it lapses or is surrendered with gains or large loans outstanding, the taxable amount can arrive with no cash to pay it. Overfunding too fast creates a MEC, in which loans and withdrawals are taxed gains-first and may carry a 10% additional tax before 59 1/2. See life insurance policy loans: how they work and what they risk and using life insurance for retirement income.
Side by side
| Roth IRA | IUL | |
|---|---|---|
| Primary purpose | Retirement savings | Life insurance with cash value |
| Funded with | After-tax contributions | After-tax premiums |
| 2026 annual limit | $7,500 ($8,600 at 50 and over) | No IRS cap; limited by section 7702 and MEC tests |
| Income limit | Yes, phased out | None |
| Ongoing costs | Fund expenses, often low | Cost of insurance, fees, loads; surrender charges for 10 to 15 years |
| Investment return | Whatever the investments earn, including losses | Index credit after cap, participation rate and spread; floor usually 0% |
| Access before 59 1/2 | Contributions anytime; earnings may be taxed and penalized | Loans and withdrawals any time, subject to policy terms |
| Required distributions | None for the owner | None |
| Creditor/estate | Account balance passes to beneficiaries | Death benefit passes income-tax-free |
| Main risk | Market losses | Charges, non-guaranteed terms, lapse |
Where the pitch breaks down
Cost drag. The Roth IRA's growth is the investments' growth less small fund fees. IUL's growth is a capped credit less insurance and administrative charges. In the early years, much of each premium goes to charges, and surrender charges can last 10 to 15 years. The tax advantage has to outrun those costs.
Illustrated vs actual. IUL pitches often compare a steady illustrated rate with a Roth IRA's volatile historical returns. NAIC Actuarial Guideline 49 limits illustrated rates and loan leverage, and the 2026 amendment (effective April 1, 2026, per Lincoln Financial's summary) restricts side-by-side comparisons of historical averages with the maximum illustrated rate. Ask for the guaranteed column and a lower-rate version. See IUL illustrations and Actuarial Guideline 49.
Loan mechanics. A policy loan is not a free withdrawal. Interest is charged, indexed loans can forgo credits on the borrowed amount, and the loan balance can cause the policy to lapse. overloan protection riders: how they prevent a taxable lapse can help in some designs.
Different jobs. A Roth IRA gives you flexible savings; IUL gives you a death benefit. If you need coverage to age 90 or beyond, you are paying for that either way.
A hypothetical comparison
Say a 40-year-old with a $6,000 annual budget can either fund a Roth IRA or an IUL premium. This is an illustration of the arithmetic, not a forecast. In the Roth IRA, the whole $6,000 is invested, and the balance reflects market results. In the IUL, a portion pays the cost of insurance and fees each month, and the remainder earns capped, floored credits. If the IUL's illustration shows a higher value, check which assumptions produce the difference, how it changes at a 4% to 5% illustrated rate, and what the death benefit provides that the Roth does not.
A sensible order
- Capture any employer 401(k) match (IUL vs 401(k): why the comparison misleads).
- Fund a Roth IRA if you are within the income limits, or a traditional IRA otherwise.
- Compare term-plus-investing with permanent coverage if you have a lifelong need; see buy term and invest the difference: does it hold up.
- Consider IUL only after steps 1 to 3 and only if you can fund it for many years.

Key takeaways
- Roth IRA 2026 limit is $7,500 ($1,100 more at 50 and over), with income phase-outs of $153,000 to $168,000 single and $242,000 to $252,000 joint.
- IUL has no IRS annual cap, but charges, caps and surrender periods weigh on early results.
- IUL loans are generally tax-free only if the policy stays in force and is not a MEC; a lapse can create a tax bill.
- Compare using guaranteed and lower-rate illustrations, not the steady-rate projection alone.
