Tax-Advantaged Account Hierarchy
If you have limited money to invest, prioritize in this order:
1. 401(k) to get full employer match (mandatory; free money) 2. Max out HSA (if available; most tax-efficient) 3. Max out IRA (Traditional or Roth) 4. Max out 401(k) (up to $23,500 annual limit) 5. Max out 529 (if you have kids for college) 6. Taxable brokerage account (whatever remains)
Let's explore each account type.
401(k): Employer-Sponsored Plan
Contribution limit (2024): $23,500/year ($30,500 if age 50+)
Key features:
- Pre-tax contributions (reduce taxable income)
- Tax-deferred growth
- Employer match (free money)
- Loans available in emergencies
- Vesting schedule (match may not be yours if you leave early)
Tax benefit example:
- Contribute $23,500 to 401(k)
- Taxable income reduction: $23,500
- Tax savings (24% bracket): $5,640
- Your actual cost: $23,500 - $5,640 = $17,860
The government subsidizes your retirement savings by $5,640 through the tax deduction.
IRA: Individual Retirement Account
Contribution limit (2024): $7,000/year ($8,000 if age 50+)
Two types:
Traditional IRA:
- Pre-tax contributions
- Tax-deferred growth
- Taxed on withdrawal
- Required Minimum Distributions at age 73
Roth IRA:
- Post-tax contributions
- Tax-free growth
- Tax-free withdrawals forever
- No Required Minimum Distributions
Income limits for Roth:
- Single: Can contribute fully if income below $146,000 (2024)
- Married filing jointly: Can contribute fully if income below $230,000
High earners use "backdoor Roth" (contribute to Traditional, immediately convert to Roth).
Combined limit: $7,000 across all IRA accounts (Traditional + Roth combined)
You can't contribute $7,000 to Traditional and $7,000 to Roth; total is $7,000.
HSA: Health Savings Account (Most Overlooked)
The HSA is the most tax-efficient account available.
Contribution limit (2024):
- Individual: $4,150/year
- Family: $8,300/year
Three tax advantages (triple tax advantage):
- Contributions are pre-tax (reduce taxable income)
- Growth is tax-free
- Withdrawals for qualified medical expenses are tax-free
Worked example: HSA tax efficiency
You contribute $4,150/year to HSA for 30 years at 8% returns.
- Total contributions: $124,500
- Investment growth: ~$535,000
- Total value: ~$659,500
- Withdraw for medical expenses: ~$659,500 completely tax-free
If you put the same $4,150/year in a taxable brokerage account:
- Total value: Same ~$659,500
- Capital gains tax on growth (15%): ~$80,000
- Net after-tax: ~$579,500
HSA advantage: $80,000+ in tax savings over 30 years
Eligibility requirement: Must be enrolled in High Deductible Health Plan (HDHP)
- Typically plans with $1,500+ deductible (individual) or $3,000+ (family)
- Many employer plans offer HDHP option
Withdrawal rules:
- For qualified medical expenses: Tax-free anytime
- For non-medical expenses before age 65: Taxed + 20% penalty
- For non-medical expenses after age 65: Taxed (no penalty)
- Can reimburse yourself tax-free for past medical expenses (keep receipts)
529: Education Savings Plan
Contribution limits:
- Annual gift tax exclusion: $18,000/year per donor per beneficiary (2024) without filing gift tax return
- Aggregate limit: $235,000 per beneficiary across all 529 accounts
Tax benefits:
- Contributions: Not federally tax-deductible (but some states offer deduction)
- Growth: Completely tax-free
- Withdrawals: Tax-free if used for qualified education expenses
Qualified expenses:
- Tuition and fees
- Room and board
- Books and supplies
- Computer and equipment
- Up to $35,000 lifetime for K-12 private school
- Up to $35,000 lifetime rollover to Roth IRA (for beneficiary)
Example: 529 growth
Parent of newborn opens 529 with $5,000/year contribution for 18 years (until college).
- Total contributions: $90,000
- Investment growth (7% return): ~$71,000
- Total value at age 18: ~$161,000
- Use for tuition: All $161,000 withdrawn tax-free
- Tax savings: ~$24,000 (15% capital gains rate on growth)
Drawback: Non-qualified withdrawals (not used for education) are taxed + 10% penalty on growth.
New rule (2024): Can roll up to $35,000 from 529 to beneficiary's Roth IRA (converting education savings to retirement savings).
Coverdell ESA: Education Savings Account
Contribution limit: $2,000/year per beneficiary
Tax benefits:
- Post-tax contributions (no deduction)
- Tax-free growth
- Tax-free withdrawals for qualified education expenses (K-12 and college)
Less common than 529 because:
- Much lower contribution limit ($2,000 vs. $235,000 aggregate)
- Income phase-out (can't contribute if income too high)
When to use: If 529 isn't available in your state or you want K-12 education flexibility.
Dependent Care FSA: Pre-Tax Childcare
Contribution limit: $5,000/year
How it works:
- Pre-tax contributions for childcare expenses
- Reduce taxable income
- Use funds to pay daycare, after-school care, summer camp
Example:
- Childcare expenses: $8,000/year
- Dependent Care FSA contribution: $5,000 (reduce from taxable income)
- Tax savings (24% bracket): $1,200
- Pay remaining $3,000 from after-tax income
- You save $1,200 in taxes on the childcare you're already paying
Comparing Contribution Limits
Annual contribution limits (2024):
| Account | Limit | Age 50+ |
|---|---|---|
| 401(k) | $23,500 | $30,500 |
| Traditional IRA | $7,000 | $8,000 |
| Roth IRA | $7,000 | $8,000 |
| HSA Individual | $4,150 | $5,150 |
| HSA Family | $8,300 | $9,300 |
| 529 | $235k aggregate | $235k aggregate |
| Dependent Care FSA | $5,000 | $5,000 |
| Total possible | ~$48,650 | ~$62,150 |
You can max everything if you have sufficient income and family situation.
Worked Example: Maximizing Tax-Advantaged Accounts
Scenario: Married couple, both age 35, earning $200k combined
Has one child (age 5), high deductible health plan.
Step 1: 401(k) to employer match (mandatory)
- Both max employer match at 3%: $7,200 combined
- Tax savings: $1,728
Step 2: Max HSA
- Family HSA: $8,300
- Tax savings: $1,992
Step 3: Max IRA (both)
- Two Roth IRAs (they're young, likely in lower bracket): $14,000
- No tax savings on Roth, but future growth is tax-free
Step 4: Max 401(k) (both)
- Both contribute to full 401(k) limit: $47,000
- Tax savings: $11,280
Step 5: Max 529
- Contribute $15,000 to child's 529 (can gift to multiple beneficiaries if more kids)
- No federal deduction (state varies)
Step 6: Dependent Care FSA
- Contribute $5,000 (they pay $10k/year childcare)
- Tax savings: $1,200
Total annual tax-advantaged contributions: ~$96,500 Total tax savings: ~$16,200 Out-of-pocket cost: ~$80,300
They've reduced taxable income from $200k to $103,500, reducing tax burden significantly.
Employer Match in Multiple Plans
Question: Can I get employer match in both 401(k) and Roth 401(k)?
Answer: Yes, but with limits.
- You can contribute to both Traditional and Roth 401(k) simultaneously
- Combined limit: $23,500 total
- Example: $12,000 Traditional + $11,500 Roth = $23,500 (at limit)
- Employer match (usually 3%): Applied to total, not split
Strategic Account Order in Withdrawal
In retirement, withdraw in this tax-efficient order:
- Taxable brokerage account first (no taxes on contributions, only capital gains)
- Roth IRA second (completely tax-free)
- Traditional IRA/401(k) last (all taxed as ordinary income)
This minimizes tax impact in retirement.
Action Items: Maximize Tax-Advantaged Accounts
- Enroll in 401(k): To at least get full employer match
- Check for HDHP availability: If available, max HSA (most overlooked account)
- Choose IRA type: Roth if young (tax-free growth), Traditional if high income now
- Open 529 if you have kids: Even small amounts compound significantly
- Coordinate with spouse: Both can have separate IRAs and HSAs
- Track contribution limits: Hit them all if possible
- Adjust W-4 accordingly: As contributions reduce taxable income, adjust withholding
Using tax-advantaged accounts is one of the highest-return strategies available. Every dollar contributed is a dollar earning investment returns without taxes.
