Tax Treatment Deep Dive

Tax-DEFERRED (Traditional 401K & IRA)

  1. 1.Contribute pre-tax dollars → reduce taxable income today
  2. 2.Money grows tax-deferred → no annual taxes on gains
  3. 3.Withdraw in retirement → pay ordinary income tax on EVERYTHING

Example: $500,000 401K at retirement

Your contributions: $200,000

Growth: $300,000

Taxes at 25%: -$125,000

Net to you: $375,000

Tax-FREE (Roth 401K, Roth IRA, IUL)

  1. 1.Contribute after-tax dollars → no deduction today
  2. 2.Money grows tax-free → no annual taxes on gains
  3. 3.Access tax-free → qualified withdrawals (Roth) or loans (IUL)

Example: $500,000 Roth or IUL at retirement

Your contributions: $200,000

Growth: $300,000

Taxes: $0

Net to you: $500,000

Difference: $125,000 more in your pocket.

Contribution Limits Comparison

The limits you can contribute matter significantly over time. IUL has no statutory cap— only limited by your death benefit structure.

401K$23,000$575,000$1,580,000
Roth IRA$7,000$175,000$475,000
Combined 401K + Roth$30,000$750,000$2,055,000
IUL ($50K/year)$50,000$1,250,000$3,200,000

Forced Withdrawals You Can't Control

Required Minimum Distributions

Starting at age 73, you MUST withdraw a percentage from Traditional 401K & IRA:

AgeRMD PercentageOn $1,000,000
733.77%$37,700
754.07%$40,700
805.35%$53,500
856.76%$67,600
908.77%$87,700

Problems with RMDs:

  • Taxable income whether you need it or not
  • Can push you into higher tax brackets
  • Triggers Social Security taxation
  • Increases Medicare premiums (IRMAA)

Roth IRA & IUL: No RMDs. You control when you access your money.

Why Tax Diversification Matters

Nobody knows future tax rates. With $34 trillion in debt and entitlement funding challenges, tax rates could rise significantly. Having money in different tax buckets gives you flexibility—pull from tax-free when rates are high, tax-deferred when rates are low.

Optimal Strategy by Income Level

Under $100K Income

  1. 1.401K up to employer match (free money)
  2. 2.Roth IRA (if under income limit)
  3. 3.Max 401K (Roth if available)
  4. 4.Taxable brokerage for additional savings

$100K - $200K Income

  1. 1.401K up to employer match
  2. 2.Roth IRA (if under income limit)

  4. 4.Begin exploring IUL for tax diversification

$200K - $400K Income

  1. 1.401K up to employer match
  2. 2.Backdoor Roth IRA ($7K)
  3. 3.Mega Backdoor Roth (if plan allows)
  4. 4.IUL for significant tax-free capacity

$400K+ Income

  1. 1.401K up to employer match (diminishing value)
  2. 2.IUL as primary tax-free vehicle
  3. 3.Taxable brokerage for liquidity

Matt Nye's Recommendation

20+ Years in Financial Services

1. Get the 401K match. Period. It's 50-100% instant return.

2. Fund a Roth IRA if you qualify. Simple, cheap, tax-free. Do it.

3. DON'T automatically max your 401K beyond the match. You're filling a tax bucket that will be emptied later at unknown rates.

4. For high earners ($200K+), use IUL for serious tax-free capacity. It's the only vehicle without income limits OR contribution caps.

Frequently Asked Questions

It depends on your current tax bracket vs. expected retirement bracket. High earners in peak years often benefit from Traditional. But having SOME Roth is valuable for tax diversification.
Yes! Most high earners should have 401K (for match), Roth IRA (for simple tax-free), IUL (for serious tax-free capacity), and brokerage (for liquidity).
Use Traditional 401K to the match, then prioritize Roth IRA and IUL for tax-free growth.
Key factors: current income, expected retirement income, state taxes, risk tolerance, time horizon, and estate planning goals. A personalized analysis is worth the time.
Health Savings Accounts are excellent (triple tax advantage). If eligible, max these too. They can function as stealth retirement accounts after age 65.
