The Order That Saves You The Most Money

You have a paycheck. You want to invest some of it. There are five or six different accounts you could use — and the order you fill them matters a lot.

Here's the ranking most financial planners agree on. Follow it from top to bottom.

1. 401(k) Up To The Employer Match

If your employer matches your 401(k) contributions, that's free money — typically a 50% to 100% instant return. Nothing else in finance comes close.

Fill this first. Even if you don't max it out, get every dollar of the match.

2. HSA (If You're Eligible) — The Quiet King

The Health Savings Account is the only triple-tax-advantaged account in the entire U.S. tax code:

• Contributions are tax-deductible (just like a 401(k));
• Growth is tax-free (just like a Roth);
• Withdrawals for medical expenses are tax-free (no other account does this).

It's basically a 401(k), Roth IRA, and FSA combined into one. And after age 65, you can use the money for anything — you just pay ordinary income tax on non-medical withdrawals (same treatment as a Traditional IRA).

2026 HSA contribution limits:

• Self-only coverage → $4,400;
• Family coverage → $8,750;
• Age 55+ catch-up → +$1,000.

The catch: you need to be enrolled in a High-Deductible Health Plan (HDHP) to contribute.

3. Max Out Your 401(k) Or Roth IRA

After the match and HSA, push toward maxing out a 401(k) or contributing to a Roth IRA, depending on your income and tax-bracket situation:

• 2026 401(k) limit → $24,500 (+$8,000 catch-up at 50+, +$11,250 super catch-up at 60–63);
• 2026 IRA/Roth IRA limit → $7,500 (+$1,100 catch-up at 50+).

Roth IRA income limits (2026): phase-out at $153,000–$168,000 single, $242,000–$252,000 joint.

4. Taxable Brokerage

After all tax-advantaged accounts are filled, anything extra goes into a regular brokerage. Less tax efficiency, but no contribution caps and no withdrawal rules.

Why The HSA Wins Long-Term

Here's the move advanced investors make:

• Contribute the max to the HSA every year;
• Don't spend it on current medical bills — pay those out of pocket;
• Invest the HSA in index funds;
• Save every medical receipt;
• Decades later, withdraw tax-free using the old receipts — or just use it as a stealth retirement account.

A $4,400 contribution invested at 7% for 30 years grows to about $33,500 — completely tax-free if used for medical expenses (and you'll have those in retirement, guaranteed).

Most people use their HSA like a debit card. They're leaving the best account in the U.S. tax code on the table.
