401(k), IRA, HSA, or Taxable Account? A Sensible Order for Your Next Dollar
October 21, 2026
When you have limited money to save, the order in which you fill different accounts affects your long-term results. A widely used sequence for US savers ranks accounts by the size of their tax advantage and the certainty of the benefit. First, contribute to your employer retirement plan enough to get the full match. Second, build a basic emergency fund and pay off high-interest debt. Third, contribute to a health savings account (HSA) if you are eligible. Fourth, fund a Roth or traditional IRA. Fifth, return to the 401(k) and contribute up to the limit. Sixth, invest in a taxable brokerage account.
The rationale is straightforward: each step offers the next-best combination of return and tax benefit. Limits change annually, so check current figures.

A match is free money: if your employer matches 50% of the first 6% of salary you contribute, saving 6% of an $80,000 salary ($4,800) brings $2,400 from your employer, an immediate 50% return. No other investment can match that. Make sure you contribute enough to capture the full match, and check whether there is a vesting schedule. Include this before paying down moderate-interest debt, though credit card debt above about 15% to 20% is a competing priority, since paying it off gives a guaranteed return of the same amount.
Steps 2 and 3: Safety Net and HSA
An emergency fund of at least one month of expenses, building toward three to six months, prevents you from needing to take on debt or tap retirement accounts. With a qualifying high-deductible health plan, an HSA's triple tax benefit (deductible contributions, tax-free growth, tax-free medical withdrawals) makes it among the best accounts. Even if you pay medical costs out of pocket, the funds can be invested for the long term.
Steps 4 to 6: IRA, Full 401(k), and Taxable
IRAs usually offer broader investment choices and lower fees than many 401(k) plans. A Roth IRA is attractive if you expect higher taxes in retirement or want flexibility; income limits apply. Once you have used the IRA, return to the 401(k) until you reach the annual limit, taking advantage of the pre-tax or Roth benefits. If your 401(k) is high-cost, consider prioritizing the IRA before contributing more beyond the match. After tax-advantaged accounts are full, use a taxable brokerage account with tax-efficient index funds, which offers flexibility and favorable long-term capital gains rates.
| Priority | Account | Why it ranks here |
|---|---|---|
| 1 | 401(k) up to the employer match | Immediate 50% to 100% return |
| 2 | Emergency fund and high-interest debt | Protection and guaranteed returns |
| 3 | HSA (if eligible) | Triple tax advantage |
| 4 | Roth or traditional IRA | Tax advantages, wider choices, lower costs |
| 5 | 401(k) up to the limit | Large tax-advantaged capacity |
| 6 | Taxable brokerage account | Flexibility, no limits |
A Numeric Example
Suppose you can save $1,500 a month on an $80,000 salary with a 50% match on 6%. First, $400 a month (6% of salary) goes to the 401(k) for the match, bringing $200 a month from your employer. Then $300 builds the emergency fund until it reaches your target. Next, $300 a month goes into an HSA (about $3,600 a year, within typical family limits for some plans; check the current ones). Then $500 a month into a Roth IRA ($6,000 a year, near the typical IRA limit). Once the emergency fund is full, its $300 can go back to the 401(k). The details depend on limits, eligibility, and goals.
At 7% for 30 years, the $400 a month plus the $200 employer match grows to about $732,000, and the match alone accounts for about $244,000 of that.
When to Deviate
If your 401(k) offers no match and has high fees, an IRA may come first. If you expect to need money before retirement, a taxable account or Roth contributions (which you can withdraw without penalty) offer more flexibility. If you are close to a tax bracket boundary, weigh traditional versus Roth contributions. Business owners, high earners, and those with other situations may have additional options like solo 401(k)s and backdoor Roth IRAs. Consult a financial adviser for specifics.
