Tax-Advantaged Accounts Guide
Tax-advantaged accounts are the most powerful wealth-building tool available. Using them well saves tens of thousands over a lifetime.
The Power of Tax-Advantaged Accounts
| Account Type | Tax on Contributions | Tax on Growth | Tax on Withdrawals |
|---|---|---|---|
| Traditional 401k/IRA | Deductible now | Tax-deferred | Taxed as income |
| Roth 401k/IRA | After-tax | Tax-free | Tax-free |
| HSA | Deductible now | Tax-free | Tax-free (for medical) |
| 529 | Not deductible (federal) | Tax-free | Tax-free (education) |
| Taxable brokerage | After-tax | Taxed yearly | Capital gains tax |
The Tax Advantage in Numbers
$10,000 invested for 30 years at 7%:
Taxable account (15% capital gains): ~$67,000
Traditional IRA (pre-tax, 22% bracket): ~$76,000
Roth IRA (after-tax, 22% bracket): ~$59,000
(Note: Roth is after-tax, so you start with less — $7,800 vs $10,000)HSA: $10,000 grows to ~$76,000 and can be withdrawn tax-free for medical expenses — the best of both worlds.
Account Order of Operations
- 401(k) up to employer match — Immediate 50-100% return
- HSA (if eligible) — Triple tax advantage
- Roth IRA — Tax-free growth, contribution access
- Max 401(k) — Max out to $23,500
- Backdoor Roth IRA (if income too high for Roth)
- Mega backdoor Roth (if 401k allows after-tax contributions)
- Taxable brokerage — No limits, less tax-efficient
HSA: The Ultimate Retirement Account
Health Savings Accounts are available with HDHP plans only.
| Feature | HSA | FSA (Flexible Spending Account) |
|---|---|---|
| Contribution | $4,300 (single), $8,600 (family) | $3,200 |
| Rollover | Yes (forever) | No (use it or lose it) |
| Invest | Yes (after $1,000-2,000) | No (spending account) |
| Triple tax-free | Yes (contribute, grow, withdraw tax-free) | No |
| After 65 | Use for any expense (taxed as income if non-medical) | Not available |
HSA Investment Strategy
| Balance | Action |
|---|---|
| $0-2,000 | Keep as cash for current medical expenses |
| $2,000-5,000 | Invest 50% in low-cost index fund |
| $5,000+ | Invest 80-100% in index fund |
The HSA strategy: Don’t use it for medical expenses now. Pay out of pocket, save receipts, and reimburse yourself tax-free decades later.
Backdoor Roth IRA
For high earners who can’t contribute directly to a Roth IRA.
| Step | Action |
|---|---|
| 1 | Contribute $7,000 to Traditional IRA (non-deductible) |
| 2 | Convert Traditional IRA to Roth IRA |
| 3 | Pay tax on any pre-tax IRA balance (pro-rata rule) |
Pro-rata rule: If you have $50,000 in other Traditional IRAs, the conversion is 50% taxable, not 100%.
Mega Backdoor Roth
For employees with 401(k) plans that allow after-tax contributions and in-plan Roth conversions.
| Limit | Amount (2026) |
|---|---|
| 401k elective deferral | $23,500 |
| Employer match | ~$11,000 |
| After-tax contributions | ~$31,000 |
| Total 401k limit | $66,000 (or $73,500 for 50+) |
How it works:
- Max pre-tax 401k ($23,500)
- Contribute after-tax dollars (up to $66,000 total)
- Convert after-tax to Roth (in-plan conversion or in-service distribution)
- Now you have Roth money growing tax-free — up to $42,500/year extra
Account Types Comparison
| Feature | 401(k) | IRA | HSA | 529 | Taxable |

| Loan allowed | Yes (up to $50K) | No | No | No | Yes (margin) |
