Account Comparison Matrix

401(k) Plans

Traditional 401(k)

Employer-sponsored plan with pre-tax contributions.

2025 Limits:

• Employee contribution: $23,500
• Employer match: Up to 100% of first 3-6% (typical: 4%)
• Catch-up (50+): Additional $7,500
• Total possible: $70,000

Tax Benefits:

• Contributions reduce current taxable income
• $10,000 contribution = ~$2,400 tax savings (24% bracket)
• Growth is tax-deferred
• Pay taxes when withdrawing in retirement

Employer Match Example:

Company offers 100% match up to 4% of salary:

Scenario 1: Employee contributes 4%

• Salary: $60,000
• Employee contribution: $2,400
• Employer match: $2,400
• Total to account: $4,800
• Employee investment: $2,400 (employer gives $2,400 free)
• Instant 100% return on investment!

Scenario 2: Employee contributes 0%

• Missing out on $2,400 free money per year
• Over 10 years: $24,000+ in lost employer contributions
• This is the easiest wealth-building opportunity

Roth 401(k)

Employer plan with post-tax contributions, tax-free growth.

Key Differences from Traditional:

Best For:

• Younger workers (more growth potential)
• Expect higher tax bracket in retirement
• Don’t need current tax deduction

Roth 401(k) Advantage:

• Can withdraw contributions (not earnings) anytime
• Larger limit than Roth IRA ($23,500 vs. $7,000)

401(k) Withdrawal Rules

Penalty-Free Withdrawals (Before 59.5):

• Disability or serious illness
• Substantially equal periodic payments (SEPP)
• Separation from service at 55+

Standard Withdrawal (59.5+):

• Tax on traditional contributions + all growth
• No penalty

Loan Option:

• Borrow up to $50,000 or 50% of balance
• Repay over 5 years (longer if home purchase)

• Risk: If you leave job, loan must be repaid quickly

IRA Accounts

Traditional IRA

Individual retirement account with tax-deductible contributions.

2025 Limits:

• Annual contribution: $7,000
• Catch-up (50+): Additional $1,000
• Total: $8,000 maximum

Deductibility Rules:

You can deduct full contribution IF:

• You have no workplace 401(k), OR
• Your income is below phase-out range

Phase-out ranges (2025):

• Single: $77,000-$87,000 (full below $77k, partial, none above $87k)
• Married: $123,000-$143,000

Example: Single earner making $60,000 with no workplace plan

• Can deduct full $7,000 contribution
• Tax savings: ~$1,680 (24% bracket)

Required Minimum Distributions (RMD):

• Begin at age 73
• Calculated as: Account balance ÷ life expectancy factor
• Example: $500,000 at age 73 = ~$18,000 required withdrawal
• Penalty for not withdrawing: 10% of shortfall (reduced from 25%)

Roth IRA

Individual account with after-tax contributions, tax-free growth.

2025 Limits:

• Annual contribution: $7,000
• Catch-up (50+): $1,000
• Income phase-out (single): $146,000-$161,000

Key Advantages:

1. No RMDs - Keep growing your money tax-free for life
2. Tax-free withdrawals - All growth is free from taxes
3. Early withdrawal flexibility - Can withdraw contributions anytime
4. Backdoor option - High earners can use backdoor Roth strategy

Backdoor Roth Strategy:

For those earning too much for direct Roth contribution:

1. Contribute $7,000 to Traditional IRA (non-deductible)
2. Immediately convert to Roth IRA
3. Pay minimal taxes on conversion
4. Result: $7,000 more in Roth (legal tax loophole)

Roth Conversion Timeline:

Traditional vs. Roth IRA Decision

Choose Traditional IRA if:

• Need current tax deduction
• Expect lower tax bracket in retirement
• Want to minimize current year income

Choose Roth IRA if:

• Expect higher tax bracket in retirement
• Want complete tax-free withdrawals
• Want flexibility (RMD-free)
• Young with decades to grow

Example Comparison:

Worker A (Traditional):

• Contributes $7,000 (deduction saves $1,680 in taxes)
• Account grows to $100,000 over 20 years
• Withdraws in retirement: $100,000 is income, taxed at ~24%
• Pays ~$24,000 in taxes

Worker B (Roth):

• Contributes $7,000 post-tax (costs $9,240 with taxes)
• Account grows to $100,000 over 20 years
• Withdraws in retirement: $100,000 tax-free
• Pays $0 in taxes
• Better if tax rates increase or you live long life

HSA - The Triple Tax Advantage

Health Savings Account is the most tax-advantaged account available.

2025 Limits:

• Individual: $4,150
• Family: $8,300
• Catch-up (55+): Additional $1,000

Triple Tax Advantage:

1. Contribution is deductible - Reduces current taxable income
2. Growth is tax-free - Investments grow without tax drag
3. Withdrawals are tax-free (for qualified medical expenses)

Result: Unlike any other account, HSAs offer complete tax exemption at three stages.

HSA Eligibility

Must have:

• High-deductible health plan (HDHP)
• HDHP 2025: Deductible $1,650+ (self-only) or $3,300+ (family)
• Cannot have other health coverage
• Cannot be claimed as dependent

Not HSA Eligible:

• Traditional health insurance with low deductibles
• Medicare recipients
• Covered under spouse’s non-HDHP plan

HSA Investment Strategy

Most People Underutilize HSAs:

Mistake: Keep HSA in cash earning 0%

• $4,150 annual contribution over 30 years = $124,500 at 0% return

Smart Strategy: Invest HSA money

• Same $124,500 invested at 6% = $347,000
• Tax-free withdrawal for medical expenses
• Difference: $222,000 more wealth!

Recommended HSA Investment:

1. Keep $1,500-$2,000 cash for immediate medical needs
2. Invest remaining $2,000-$2,650 in index funds
3. Treat as retirement account (can pay medical out-of-pocket, let HSA grow)
4. Withdraw tax-free for medical expenses after 65 (becomes like IRA if not medical)

Employer Match - Free Money

Why Employer Match is Critical

Free Money Analysis:

Employer offers 100% match up to 4%:

Over 30-Year Career:

• Contribute $2,400/year to get match
• Employer contributes $2,400/year
• Total $4,800/year × 30 years = $144,000
• Growth at 6%: ~$600,000+
• Cost to you: Only 4% salary reduction

This is the single easiest path to wealth.

Contribution Sequencing Strategy

If you have limited money for retirement savings, use this order:

Step 1: Employer 401(k) Match

• Most important: Get free money first
• Contribute enough to capture full match
• Typical: 4-6% of salary

Step 2: Max HSA (if eligible)

• Triple tax advantage
• Only account with three tax benefits
• $4,150-$8,300 annually

Step 3: Max IRA

• $7,000 annually
• Choose Roth vs. Traditional based on situation
• More control than 401(k)

Step 4: Max 401(k)

• Contribute remaining to 401(k) up to $23,500
• Tax-advantaged growth with employer match

Step 5: Taxable Investment Account

• After maxing tax-advantaged accounts
• Remaining investment money
• Less tax-efficient but unlimited

Example Income Allocation

Gross Income: $80,000

Result: $24,350 saved for retirement from $80,000 salary, with $4,164 tax savings.

Withdrawal Strategies in Retirement

The Roth Conversion Ladder

Strategy to retire early (before 59.5) without penalties:

1. Convert Traditional IRA to Roth IRA
2. Wait 5 years (Roth conversion rule)
3. Withdraw conversion amount penalty-free at 59.5 or earlier
4. Build “ladder” with annual conversions

Benefits:

• Access retirement funds before 59.5
• Pay taxes during low-income years
• Minimize lifetime tax burden

Example:

• Age 50: Convert $50,000 traditional to Roth (pay taxes on conversion)
• Age 55: Can withdraw $50,000 conversion penalty-free
• Create ladder with multiple $50,000 conversions
• By age 59.5, have access to ladder of conversions

Required Minimum Distributions (RMD) Planning

Starting Age 73:

RMD = Account balance ÷ IRS life expectancy factor

2025 Example:

• Traditional IRA balance: $500,000
• Age 73: RMD factor = 27.4
• Required withdrawal: $18,248

RMD Planning Strategies:

1. Take excess distributions early (build Roth balances)
2. Use distributions to fund charitable donations
3. Do Qualified Charitable Distributions (QCD) to avoid taxable income
4. Plan Social Security coordination

Penalty for Missing RMD:

• Reduced from 25% to 10% of shortfall (2024 rule)
• Better to over-withdraw than under-withdraw

Tax Loss Harvesting in Taxable Accounts

While tax-advantaged accounts are priority, taxable accounts benefit from tax loss harvesting.

Strategy:

• Sell losing positions
• Realize loss for tax deduction
• Immediately buy similar (not identical) investment
• Deduct $3,000 loss against ordinary income
• Carry forward remaining losses

Example:

• Bought $10,000 stock, now worth $8,500
• Sell for $1,500 loss
• Buy similar company stock (not identical)
• Deduct $1,500 loss
• Tax savings: ~$360 (24% bracket)

Case Study: Three Retirement Plans

• Roth IRA: $7,000/year
• Total: $19,000/year × 30 years
• Growth: 6%
• Final balance: $1,537,000
• Total contributed: $570,000

Worker C: All Tax-Advantaged (401k + IRA + HSA)
