401(k) + Roth IRA + IUL: The Complete Tax Diversification Strategy
No single retirement account does everything. The 401(k) gives you the employer match and a current tax deduction. The Roth IRA gives you a tax-free foundation. IUL gives you unlimited additional tax-free income with a death benefit. Together, these three create the most comprehensive, tax-diversified retirement income plan available - the gold standard for high earners serious about retirement.

Our Verdict: Who Should Choose What
High Earners ($200K+)
IUL is often the best choice
Roth IRA income limits make it inaccessible or limited. IUL has no income limits and no contribution caps.
Average Earners with Room in Roth
Max Roth IRA first, then IUL
Roth IRA is simpler and lower cost. Once maxed, IUL provides additional tax-free accumulation capacity.
Those Needing Early Retirement Access
IUL has a clear edge
IUL policy loans are available at any age with no penalty. 401(k) and traditional IRAs impose a 10% penalty before 59.5.
Estate Planning Focus
IUL wins on death benefit
IUL provides an income-tax-free death benefit to heirs, which qualified accounts do not offer.
The Bottom Line
The 401(k) + Roth IRA + IUL combination is the gold standard of tax-diversified retirement planning for anyone earning $100,000 or more. Each account plays a distinct role: the 401(k) captures free employer money and current deductions, the Roth builds the tax-free foundation, and IUL provides unlimited additional tax-free income with a death benefit. Together, they allow a retirement income strategy where the effective tax rate on total spending can be dramatically lower than any single-account approach.
IUL Advantage: For high earners and those who've maxed out qualified accounts, IUL offers unlimited contributions, no RMDs, and tax-free income through policy loans - advantages that no qualified retirement account can match.
