Retirement account order of operations

With a 401(k), IRA, HSA, Roth, traditional, and maybe a taxable brokerage to choose from, 'where do I put the next dollar' becomes a real question. Here's the consensus order for most people.

The order

1. 401(k) up to the full employer match. Free money — always first.
2. Pay off high-interest debt (anything above ~7%).
3. Fully fund an HSA if you have a high-deductible health plan. Triple tax-advantaged, best account that exists.
4. Max a Roth IRA if eligible ($7,000 in 2026, $8,000 if 50+). Tax-free growth for life.
5. Finish maxing the 401(k) up to the $23,500 limit.
6. Backdoor Roth IRA if your income is above the direct-contribution limit.
7. Mega backdoor Roth if your plan allows (advanced).
8. Taxable brokerage for anything beyond retirement caps.
9. 529 plans, I-bonds, and other goal-specific vehicles as applicable.

Why this order and not another

The list isn't arbitrary — it ranks each dollar's destination by guaranteed return, then tax advantage, then flexibility. The employer match comes first because a 50-100% instant return beats anything else in finance. High-interest debt comes second because paying off a 24% credit card is a guaranteed 24% return, tax-free and risk-free. The HSA outranks the Roth IRA because it is the only account that is tax-free on the way in, during growth, AND on the way out (for medical costs) — plus after 65 it behaves like a Traditional IRA for non-medical withdrawals. Everything after that is sorting among good options.

A worked example: $1,500 a month

Take a 35-year-old earning $90,000 with $1,500 a month to allocate, whose employer matches 50% up to 6% of salary. Step one: contribute 6% ($450/month) to the 401(k), collecting $225 of free match money. Step two: she has a $4,000 credit card balance at 26% — the next $600/month kills it in seven months. After that, the same $600 redirects to her HSA ($366/month maxes the individual limit) and the start of a Roth IRA. Step three: the remaining $450 plus the freed-up $234 finishes maxing the Roth IRA at $583/month. Every dollar has a job, and the jobs are ranked by payoff.

Common mistakes with the ladder

• Maxing the 401(k) before funding an IRA. Workplace plans often carry higher fund fees; the IRA gives you any fund on the market at rock-bottom cost. Match first, then IRA, then back to the 401(k).
• Using the HSA as a spending account. Its superpower is investing the balance and letting it compound for decades while you pay small medical bills out of pocket and bank the receipts.
• Stopping at the match. Six percent of salary plus a match is a floor, not a plan — most people need 15%+ of income saved to retire on schedule.
• Funding a 529 before your own retirement is on track. Your kid can borrow for college; you cannot borrow for retirement.
• Forgetting the spouse. A non-working spouse can fund a full spousal IRA — a second $7,000 of tax-advantaged space many couples never claim.
• Skipping the backdoor Roth out of intimidation. If you earn too much to contribute directly, the backdoor is a routine two-step at any major brokerage — but watch the pro-rata rule if you hold pre-tax IRA money.

When to deviate from the default

• Terrible 401(k) (fees above ~1% and no index options): contribute to the match, then prioritize IRA and HSA, then taxable — and lobby HR for a better plan.
• Planning to retire before 59½: after the match, a taxable brokerage moves up the list because it has no age restrictions and fills the bridge years.
• Expecting a big income jump (residency, law school, early startup years): Roth everything now while your bracket is low; you will never get these cheap tax years back.
• Self-employed: swap the 401(k) steps for a Solo 401(k), which gives you both the employee and employer contribution slots.

How the ladder changes over a career

The order isn't static across a lifetime. In your 20s, the whole ladder might be two rungs: match plus a Roth IRA, because income (and the tax benefit of Traditional deferrals) is still low. In your 40s, peak earnings usually flip the 401(k) contributions to Traditional and bring the backdoor Roth into play as income crosses the phase-out. In your 50s, catch-up contributions add roughly $8,500 of extra annual space across the 401(k) and IRA, and the HSA gains its own catch-up at 55. And in the last five to ten working years, the taxable brokerage rung quietly becomes strategic rather than residual — it's the money that funds early-retirement years and Roth conversion taxes before penalty-free account access begins.

A reasonable annual ritual: each January, confirm the match percentage hasn't changed, bump contributions by at least the year's limit increases, and ask whether any life change — marriage, a raise, a new health plan, a side business — added a rung you weren't using. Ten minutes a year keeps the whole structure current.

One more practical note: you don't need to complete each rung before starting the next. The order is about priority when dollars are scarce, not a strict sequence. Automate the match and the IRA on day one, point raises at the next rung, and re-check the ladder once a year. Most people who follow this list for a decade quietly out-save the vast majority of professional-earning households — not through cleverness, just through ordering.
