How IUL Can Work Alongside Your 401(k)
You may have heard IUL pitched as a “401(k) killer.” It isn’t — and anyone who says so is overselling it. But as a complement to your workplace plan, it can solve problems a 401(k) can’t. Here’s how.

Start with what your 401(k) does well
A 401(k) is a powerful tool. Contributions can lower your taxes today, the money grows tax-deferred, and many employers add a matching contribution — which is hard to beat anywhere else. Most planners suggest capturing any employer match before looking at other options.
And what it doesn’t
- Every withdrawal is taxed. Traditional 401(k) money is taxed as income when you take it out — at whatever tax rates exist then.
- The IRS decides when you withdraw. Required minimum distributions generally begin at 73 (75 for those born in 1960 or later).
- It’s exposed to the market. A downturn just before retirement can reduce what you have when you need it most.
- Contribution limits. Higher earners often hit the annual limit and need somewhere else to save.
- Early access is restricted. Withdrawals before 59½ usually face a 10% penalty on top of income tax.
Where an IUL can fill the gaps
A properly designed indexed universal life policy adds a different kind of bucket to your plan:
| Traditional 401(k) | Indexed universal life | |
|---|---|---|
| Tax on contributions | Pre-tax — lowers taxes now | After-tax |
| Tax on access in retirement | Taxed as income | Policy loans generally not taxed as income, if the policy stays in force |
| Market losses | Exposed | Protected from index losses by the floor |
| Required withdrawals | Yes, from your 70s | None |
| Employer match | Often | No |
| Death benefit | Account balance only | Income-tax-free death benefit, plus living benefits on many policies |
| Costs | Fund and plan fees | Insurance costs and policy charges |
The idea: tax diversification
Most families have nearly all their retirement savings in one tax bucket — tax-deferred. Adding a bucket that can be accessed without adding to taxable income gives you choices later: in a high-tax year, you could draw from the IUL; in a low-tax year, from the 401(k). That flexibility can also help manage how much of your Social Security becomes taxable.
Meanwhile, the policy protects your family with a death benefit — and, with living benefits, can help if you face a serious illness along the way.
An IUL used for retirement income must be designed and funded properly, kept in force, and reviewed over time. Policy loans that aren’t managed carefully can cause a policy to lapse, which can create a tax bill. This is a long-term strategy, not a quick fix.
Who this strategy may suit
Often a good fit…
- Already capturing the employer match
- Maxing out, or close to, their 401(k)
- Want tax-free income options in retirement
- Also need life insurance protection
Usually not the right fit…
- Not yet capturing the employer match
- No emergency savings in place
- May need the money in the next few years
- Can’t commit to funding it consistently
Curious what a tax-advantaged bucket could look like next to your 401(k)? We’ll show you — with conservative assumptions.
Book a free check-inGeneral education only, not tax or investment advice. Indexed universal life is life insurance, not an investment in the stock market or a retirement plan. Caps, participation rates, fees and charges apply, and illustrated values are not guaranteed. Policy loans and withdrawals reduce cash value and death benefit; if a policy lapses with a loan outstanding, taxes may be due. Consult your tax professional.
