Indexed Universal Life (IUL) and the Roth IRA are both prized for the same reason: tax-free income later. But they are built differently, and for most people the honest answer is not "either/or", it is "in what order."
The Roth IRA
- Funded with after-tax dollars; qualified growth and withdrawals are tax-free
- No lifetime RMDs for the original owner
- 2024 contribution limit is $7,000 ($8,000 if 50+), and high earners are phased out by income
- Simple, low-cost, fully invested, and fully exposed to market losses
Indexed Universal Life
- Permanent life insurance with cash value linked to an index and a 0% floor
- No IRS income limits and no set contribution cap (within IRS funding rules)
- Tax-free access to cash value via policy loans, plus a tax-free death benefit
- Costs of insurance and caps on growth are the trade-off for the protection
How to choose
If you qualify for a Roth and want low-cost market growth, fund the Roth first, it is hard to beat. If you are a high earner phased out of the Roth, want downside protection, need more tax-free capacity than the Roth allows, or want a death benefit and legacy component, IUL can extend your tax-free bucket where the Roth stops.
The wealthiest retirement plans usually use both: the Roth for efficient growth, the IUL for protected, uncapped-contribution tax-free income and legacy. The right split depends on your income, health, and time horizon, which is exactly the conversation to have before you commit.
