IUL vs. 401(k): the differences and which one to use first

What each one is

A 401(k) is a retirement plan offered by your employer. You contribute part of your paycheck, sometimes your employer adds money, and what is in the account is invested in the plan’s options, so it can go up or down with the market. An IRA is a personal retirement account with similar rules.

An IUL is life insurance. It protects your family with a death benefit and builds a cash value that earns interest based on an index, with a floor and a cap. It is not an investment account: FINRA explains that it is generally not considered a security.

IUL vs. 401(k): side-by-side comparison

The differences that weigh the most:

• Purpose: a 401(k) is for retirement; an IUL is first protection for your family, with cash value as an additional benefit.
• Contribution limit: a 401(k) has an IRS limit ($24,500 in 2026, plus $8,000 if you are 50 or older and $11,250 from ages 60 to 63); an IUL has no annual dollar cap, but tax law (sections 7702 and 7702A) limits how much can be paid relative to the coverage; if it goes over the 7-pay test, it becomes a MEC.
• Employer contribution: a 401(k) can have one; a personal IUL generally does not.
• Taxes when you contribute: a traditional 401(k) lowers your taxes today; IUL premiums are paid with money that has already been taxed.
• Taxes when you use the money: traditional 401(k) withdrawals are taxable, plus an additional 10% before age 59½ in most cases; loans from an IUL that is not a MEC are generally not taxable while the policy stays in force.
• Required withdrawals: a 401(k) and a traditional IRA generally require minimum distributions starting at age 73; an IUL does not.
• Risk: a 401(k) can go up and down depending on the investments you choose; an IUL has a floor, but the cap is not guaranteed and charges are always deducted.
• If you pass away: a 401(k) passes to your beneficiaries with its balance, which is generally taxable when withdrawn if it is traditional; an IUL pays the death benefit, which is generally not taxable income.

Why you should not walk away from your employer match

According to the Department of Labor, your employer may match part of your 401(k) contributions. That contribution is money on top of your paycheck, and no life insurance policy replaces it. Also check the vesting rules: some plans give you the full employer contribution only after you have worked there for a certain amount of time.

That is why, in general, a prudent order is: first the contribution your employer matches, then an emergency fund and then, if you need lifelong protection and have enough left over to pay for it consistently, an IUL or another permanent policy. Your plan administrator can confirm your plan’s rules.

Be wary of anyone who tells you to stop contributing to your 401(k) to pay for an IUL without checking whether you lose your employer match.

Where the IRA and Roth IRA fit in this comparison

In 2026 you can contribute up to $7,500 to an IRA, plus $1,100 if you are 50 or older. A Roth IRA gives you no deduction today, but its qualified withdrawals are tax-free; in 2026 you can make the full contribution if your income is no more than $153,000 (single) or $242,000 (married filing jointly); above that, the contribution phases out until it disappears at $168,000 and $252,000.

People who earn more than those limits or already max out their retirement accounts sometimes use permanent life insurance as an additional source of money while they are alive. That decision should be made with your accountant.

When adding an IUL can make sense

An IUL can complement your retirement plan if:

• You need life insurance for your whole life, not just for a few years.
• You already take advantage of your employer match and have an emergency fund.
• You can pay more than the minimum premium for many years.
• You want a source of money while you are alive that has no required withdrawals.
• You understand that the cap is not guaranteed and that the policy should be reviewed every year.

Protection from creditors (Florida)

In Florida, the law protects from creditors both qualified retirement accounts, like a 401(k) and an IRA (Statute 222.21), and the surrender value of life insurance (Statute 222.14), with some exceptions. In other states the protection of cash value is different, so it is worth reviewing it with an attorney.
