Roth vs. Traditional: What's the Difference?

1The One Difference That Drives Everything

Roth and Traditional accounts hold the same investments and grow the same way. The only difference is when the IRS collects taxes.

• Traditional: you contribute pre-tax dollars, which lowers your taxable income today. Every dollar you withdraw in retirement comes out as ordinary income and is taxed at your rate at that time.
• Roth: you contribute after-tax dollars — money you've already paid tax on. No tax break today. But the money grows completely tax-free, and qualified withdrawals in retirement are 100% tax-free.
• You never pay tax on Roth growth, no matter how large the account becomes.

2Roth vs. Traditional: The Same Logic Across All Account Types

The Roth vs. Traditional choice is not unique to IRAs. The same pre-tax/after-tax structure appears in workplace plans too. A Roth 401(k) works exactly like a Roth IRA in terms of tax treatment — after-tax contributions, tax-free growth, tax-free withdrawals — but inside an employer-sponsored 401(k) plan with much higher contribution limits. A Traditional 401(k) uses pre-tax contributions, reduces your taxable income now, and taxes withdrawals as ordinary income in retirement. The same structure applies to 403(b) plans (common in public schools, hospitals, and nonprofit organizations) and 457 plans (offered to many government employees and some nonprofit workers). Whether your plan is a 401(k), 403(b), or 457, the Roth vs. Traditional distinction works the same way — the difference is always and only about when taxes are paid.

• Roth IRA / Roth 401(k) / Roth 403(b) / Roth 457: after-tax contributions, tax-free growth, tax-free qualified withdrawals
• Traditional IRA / Traditional 401(k) / Traditional 403(b) / Traditional 457: pre-tax contributions, tax-deferred growth, ordinary income tax on withdrawals
• Workplace plans (401k, 403b, 457) have much higher contribution limits than IRAs
• Not every employer plan offers both options — check your plan documents
• Roth 457 plans are available in many government plans; confirm your plan type with your HR department

3Pre-Tax: Lower Taxes Now, Pay Later

When you contribute to a Traditional account, that money comes out of your paycheck before income tax is calculated. If you earn $70,000 and put $5,000 into a Traditional 401(k), you only pay income tax on $65,000 that year. The $5,000 goes in untaxed, grows untaxed, and gets taxed when you withdraw it in retirement. This works well when you expect to be in a lower tax bracket in retirement than you are today — you get the deduction at your higher current rate and pay the tax at your lower future rate.

4After-Tax (Roth): Pay Now, Never Again

When you contribute to a Roth account, you use money you've already paid tax on. No deduction today. But the money grows completely tax-free, and when you withdraw it in retirement, you owe nothing — no income tax on the growth, no tax on the balance you've built. For workers earlier in their careers who are in a lower tax bracket now than they expect to be at their peak, the Roth approach often produces better long-term results.

• No tax deduction today on Roth contributions
• Money grows completely tax-free inside the account
• Qualified withdrawals in retirement are 100% tax-free
• Roth IRA: no Required Minimum Distributions — the money can stay invested as long as you want
• Roth 401(k)/403(b)/457: currently subject to RMDs, but can often be rolled to a Roth IRA to avoid them
• Roth IRA contributions (not earnings) can be withdrawn at any time without penalty — added flexibility

5The Tax Uncertainty Factor

One honest reason many workers lean toward Roth accounts is uncertainty about future tax rates. Nobody knows for certain what tax rates will look like in 20 or 30 years. A Roth account locks in your tax cost at today's rates and removes future tax rate uncertainty from the equation entirely for that portion of your savings. This isn't a political prediction — it's simply a planning consideration.

6How Employer Plans Work: 401(k), 403(b), and 457

Workplace retirement plans — 401(k), 403(b), and 457 — are separate from IRAs and have much higher contribution limits. In 2024, you can contribute up to $23,000 to a workplace plan ($30,500 if you're 50 or older). The Roth vs. Traditional choice applies here too, but not every plan offers both options.

• Always capture the full employer match first — that match is an immediate return on your money that no other option can match.
• Check your plan documents or ask HR what Roth and Traditional options are available. Not all plans offer both.
• Union workers with access to annuity funds or defined benefit pensions may have different plan structures — review your specific plan documents or speak with your plan administrator.

7Which Approach Makes Sense for You

There's no single right answer — but there are useful patterns based on where you are in your career.

• Early-career workers (apprentices, young journeymen) not yet at peak earnings: Roth contributions are often better. You pay tax at a lower rate now, and decades of tax-free compounding follows.
• Mid-career workers at peak earnings: a mix often makes sense — Traditional contributions through a workplace plan to reduce taxable income today, and Roth contributions through an IRA for long-term tax-free flexibility.
• Workers close to retirement in their highest-earning years: Traditional contributions may be more beneficial, capturing the deduction at their peak rate.
• In all cases, understanding your plan's options, your current income, and your expected retirement income are the key inputs. A qualified financial professional or your plan administrator can help you think through your specific situation.
