Roth IRA vs. Traditional IRA: Which Wins?

1The Core Difference: When You Pay Tax

Both a Roth IRA and a Traditional IRA are individual retirement accounts with the same annual contribution limit ($7,000 in 2024, $8,000 if you're 50 or older). Both grow tax-deferred inside the account. The difference is in when the IRS takes its cut. With a Traditional IRA, you contribute pre-tax money — contributions may be deductible, lowering your taxable income today — and you pay income tax when you withdraw in retirement. With a Roth IRA, you contribute after-tax money — no deduction today — but your money grows tax-free and qualified withdrawals in retirement are completely tax-free.

2Traditional IRA: Pay Taxes Later

The Traditional IRA is beneficial when you expect to be in a lower tax bracket in retirement than you are today. If you're in a high-earning period now and expect lower income in retirement, the deduction today saves you money at your current higher rate, and you pay tax in retirement at your lower rate. Workers at peak earning years — journeymen in their 40s and 50s at the top of their scale — may benefit from Traditional contributions during those high-income years. Deductibility phases out at higher incomes if you or your spouse also have a workplace retirement plan.

• Contributions may be tax-deductible today (subject to income limits)
• Grows tax-deferred — no annual tax on gains
• Withdrawals in retirement taxed as ordinary income
• Required Minimum Distributions (RMDs) starting at age 73
• Best if you expect lower tax rates in retirement than today

3Roth IRA: Pay Taxes Now, Never Again

The Roth IRA is beneficial when you expect to be in the same or higher tax bracket in retirement, or when tax rates in general may be higher in the future. For younger workers — apprentices and early journeymen who aren't yet at their peak earning years — the Roth is almost always the better choice. You're in a lower tax bracket now, so you pay tax at a lower rate on your contributions, and then never pay tax on the growth or withdrawals, no matter how large the account grows. A Roth IRA that grows from $10,000 to $500,000 over 35 years generates $490,000 in completely tax-free income in retirement.

• Contributions made with after-tax money — no deduction today
• Grows tax-free — no annual tax on gains
• Qualified withdrawals in retirement are completely tax-free
• No Required Minimum Distributions — the money can stay invested
• Contributions (not earnings) can be withdrawn penalty-free at any time
• Best if you expect the same or higher tax rates in retirement, or are in a lower bracket now

4Income Limits and Eligibility

The Roth IRA has income limits. In 2024, the ability to contribute phases out at $146,000–$161,000 for single filers and $230,000–$240,000 for married filing jointly. If your income is above those thresholds, you can't contribute directly to a Roth IRA (though a 'backdoor Roth' strategy exists for higher earners). The Traditional IRA has no income limit for contributions, but the deductibility phases out if you're covered by a workplace retirement plan. Check current IRS limits, as they adjust for inflation annually.

5The Roth Advantage: Flexibility

Beyond the tax-free retirement income, the Roth IRA has a flexibility advantage: you can withdraw your contributions (not earnings) at any time without penalty or taxes. This makes the Roth IRA a hybrid between a retirement account and an accessible savings vehicle. It also has no Required Minimum Distributions, meaning you can leave the money invested and growing through your 70s and beyond, or pass it to heirs tax-free. These features don't affect the retirement math directly, but they make the Roth a more versatile account for people who value financial flexibility.

6What About a 401(k) or Union Annuity?

Many workers have access to a workplace 401(k) or union annuity on top of (or instead of) an IRA. These are separate accounts with separate contribution limits. If your employer offers 401(k) matching, contribute enough to capture the full match before funding any IRA — matching is an immediate 50–100% return that nothing else beats. After capturing the full match, many financial planners recommend funding a Roth IRA next (for the tax-free benefit), then returning to the 401(k) for additional contributions.

7Making the Decision

If you're an apprentice or early-career journeyman, the Roth IRA is almost certainly your best option. You're in a lower tax bracket now than you will be at your peak earning years, and decades of tax-free growth is worth more than a small deduction today. If you're a mid-career journeyman at your peak earning years, a mix of Traditional (through your 401(k)) and Roth (in an IRA) may be the right approach to hedge your tax exposure. If you're within 10–15 years of retirement and in high-earning years, the Traditional deduction may be worth prioritizing. When in doubt, the Roth is the safer bet for most working people.
