The Roth IRA vs Traditional IRA decision comes down to one question: do you pay taxes now, or later? Both accounts grow tax-advantaged. But they tax you at opposite ends of your investing life. Getting this decision right can save you tens of thousands of dollars over a career.

The Core Decision: Tax Now vs Tax Later
Choose a Roth IRA if:
- You are early in your career and currently in a low tax bracket
- You expect your income and tax rate to increase
- You want tax-free income in retirement regardless of future tax law
- You want flexibility: Roth contributions can be withdrawn anytime, penalty-free
Choose a Traditional IRA if:
- You are in a high tax bracket now and expect lower in retirement
- You want to reduce your taxable income this year
- You earn too much to contribute to a Roth IRA

The Backdoor Roth IRA for High Earners
If you earn too much to contribute directly to a Roth IRA, you can use the backdoor Roth strategy:
- Contribute $7,000 to a Traditional IRA (non-deductible)
- Convert it immediately to a Roth IRA
- No income taxes owed if no earnings accumulated before conversion
This is legal and widely used. Consult a tax advisor if you have other pre-tax IRA money (the pro-rata rule may apply).
Which Do Most Advisors Recommend?
For people under 40 earning under $100,000, most advisors recommend the Roth IRA. The reasoning: tax rates are historically low right now, young earners are typically in their lowest bracket, and tax-free retirement income has enormous value if tax rates increase over 30 years.

The Bottom Line
Young and lower income: Roth IRA. High income now with lower expected income in retirement: Traditional. If uncertain, the Roth is usually the safer hedge. The worst decision is not contributing to either.
