Roth vs. Traditional: which is better?
One tax-rate comparison decides it.

The Roth IRA

You contribute money you have already paid income tax on. The account grows tax-free. You withdraw tax-free in retirement. Contributions (but not earnings) can come out at any time without penalty. That flexibility makes it the single most powerful account for early-career savers.

The annual contribution limit is $7,500 for 2026, with a $1,100 catch-up for savers aged 50 and older. Contributions can be made up until the tax filing deadline (mid-April) for the prior year. Open the account at Fidelity, Schwab, or Vanguard (no account fees, no commissions on index funds). Invest the contribution in a total-market fund (VTI, FSKAX, FZROX) or a target-date fund. Do not leave the cash sitting in the settlement fund.

The 401(k)

The 401(k) is an employer-sponsored plan with a much higher contribution limit: $24,500 for 2026, plus an $8,000 catch-up at age 50+, replaced (not supplemented) by $11,250 for ages 60–63 if the plan permits ^[1]. Contributions come directly from payroll before income tax is calculated, so a $10,000 contribution reduces this year's taxable income by $10,000.

Most employers match a portion of contributions. Typical matches are 50 percent of the first 6 percent of salary, or 100 percent of the first 3 percent. The match is the highest-return investment in personal finance: a dollar that doubles on contact. Capture the full match before doing almost anything else.

Many plans now offer a Roth 401(k) option, which has the same $24,500 limit but uses after-tax dollars for tax-free growth (compared with a Roth IRA: higher limit and no income restriction, but contributions cannot be withdrawn anytime without tax or penalty). Self-employed people can open a Solo 401(k) with the same limit plus an employer-side contribution on top.

Roth vs Traditional: how to choose

The rule of thumb: choose Roth when your current tax rate is lower than your expected retirement tax rate; choose Traditional when your current rate is higher. In practice, that means early-career and moderate-income savers typically favor Roth, while high earners in peak years often prefer Traditional for the immediate deduction.

The HSA as stealth retirement account

If you are enrolled in a High-Deductible Health Plan (HDHPHigh-Deductible Health Plan (HDHP)A health-plan category with statutory deductible and out-of-pocket rules.

After age 65, non-medical withdrawals work like a Traditional IRA (income tax, no penalty).

The withdrawal rules, clearly

From a Roth IRA, you can take out everything you contributed at any time, for any reason, with no tax and no penalty. Only the growth has restrictions.

Exceptions to the 10 percent penalty on earnings:

• First home purchase (up to $10,000 lifetime).
• Disability.
• Substantially equal periodic payments (72(t)).
• Death (beneficiarybeneficiaryThe person or entity you name to receive an account or insurance policy when you die. distributions).
