Maxed Out Your 401(k)? Here’s What to Do Next (Ranked by Priority)

Priority 1: Health Savings Account (HSA) – The Triple Tax Advantage If you have a High Deductible Health Plan (HDHP), the HSA is your best option after maxing your 401(k).

Why #1:

Tax-deductible contributions (lower taxable income)

Tax-free growth (interest, dividends, capital gains)

Tax-free withdrawals for qualified medical expenses

No other account has this triple tax advantage.

2026 contribution limits:

Individual: $4,300

Family: $8,550

Age 55+: additional $1,000

Strategy: Don’t use your HSA as a daily medical reimbursement account. Treat it as a third retirement account. Pay medical expenses from other funds. Keep the HSA invested. In retirement, you can reimburse yourself for years of prior medical expenses (keep receipts) – still tax-free.

If you can’t max it: At least contribute enough to cover your deductible.

Priority 2: Backdoor Roth IRA The problem: You earn too much to contribute directly to a Roth IRA (2026: single MAGI over $161,000, married joint over $240,000).

The solution: Backdoor Roth IRA – a completely legal two-step process.

Steps:

Contribute after-tax money to a Traditional IRA (limit $7,000, $8,000 if 50+)

Immediately (within days) convert that money to a Roth IRA

Critical: Your Traditional IRA should have no pre-tax money before doing this. If it does, the “pro-rata rule” triggers taxes on the conversion. Solution: roll pre-tax IRA money into your 401(k).

Best for: High earners who want tax-free income in retirement.

Priority 3: Spousal IRA – Use Your Partner’s Limit If you don’t work or earn very little, but your spouse works – you can still have your own IRA.

The rule: As long as you file jointly and total income is at least the sum of both IRA contributions, a non-working spouse can contribute based on the working spouse’s income.

2026 limit: $7,000 each ($8,000 if 50+). A couple can contribute $14,000-$16,000.

Example: Wife earns $200,000. Husband doesn’t work. Husband can contribute $7,000 to his own IRA. This is separate from the wife’s 401(k) and IRA.

Priority 4: 529 Education Savings Plan – If You Have or Plan to Have Kids 529 plans are tax-advantaged accounts for education expenses.

Tax benefits:

Contributions: Most states offer a state tax deduction (typically $3,000-$10,000)

Growth: Tax-free

Withdrawals: Tax-free for qualified education expenses (tuition, room, board, books)

2026 changes: 529 plans can now be converted tax-free to a Roth IRA (with conditions):

529 must be open for at least 15 years

Lifetime conversion limit of $35,000

Subject to annual Roth contribution limits

Strategy: If you have kids, contribute at least enough to capture your state tax deduction. If you don’t have kids, open a 529 for yourself – future continuing education, or transfer to future children/grandchildren.

Priority 5: Taxable Brokerage Account – No Limits, Only Taxes After you’ve exhausted tax-advantaged accounts, the extra money goes to a taxable brokerage account.

Advantages:

No contribution limits

No income limits

Withdraw anytime, no penalty

Widest investment selection (individual stocks, options, bonds, REITs, any ETF)

Tax considerations:

Dividends and interest: Taxed annually

Capital gains: Taxed when you sell. Hold for over one year for preferential rates (0%, 15%, or 20%)

Strategy: In taxable accounts, prioritize tax-efficient investments:

Index ETFs (low turnover, few capital gains distributions)

Municipal bonds (interest is tax-free)

Hold for the long term (over one year)

Avoid: High-turnover active funds, REITs (non-qualified dividends taxed at higher rates), junk bonds.

Priority 6: Mega Backdoor Roth 401(k) – If Your Plan Allows It This is the least-known feature in the 401(k) world. It allows you to make after-tax (not Roth) 401(k) contributions and convert them to Roth 401(k) or Roth IRA.

2026 total limit: $70,000 (including your $23,500 contribution + employer match + after-tax contributions)

How it works:

Make after-tax contributions to your 401(k) (not pre-tax, not Roth)

Convert those after-tax dollars to Roth 401(k) or Roth IRA

Prerequisites: Your 401(k) plan must explicitly allow:

After-tax contributions

In-plan Roth conversion

How to check: Call your 401(k) provider and ask: “Does my plan allow after-tax contributions and in-plan Roth conversions?”

If yes: You can get up to $70,000 into Roth accounts (depending on employer match). This is the most powerful tool for high earners to accumulate tax-free wealth.

Priority 7: Real Estate, Private Equity, Other Alternatives Only consider after the first 6 options are exhausted.

Why last:

Illiquid (selling a house or private equity stake takes months to years)

High minimums (many private funds require $50,000-$250,000)

High fees (private equity typically charges 2% management + 20% of profits)

Concentrated risk (one property or one deal fails = big loss)

When it’s worth it:

You already have $500,000+ in traditional investments

You understand and accept liquidity risk

You have time and management ability (for direct real estate)

Better alternative for most people: REIT ETFs (e.g., VNQ) – real estate exposure with liquidity and low fees.

$400k All of the above + 529 (if kids) + significant taxable investing Conclusion Maxing your 401(k) is a milestone. But real wealth building happens after. Putting money into the right account matters more than picking the right stock. HSA, Backdoor Roth IRA, Mega Backdoor Roth – these are tools the wealthy use. Now you can too.

Immediate action: Check if your HSA is maxed today. If not, adjust your payroll deduction.
