How a Traditional IRA Works
- Contributions: You contribute pre-tax dollars. Your contributions may be tax-deductible in the year they are made, depending on your income level and whether you or your spouse are covered by a workplace retirement plan (like a 401(k)).
- Growth: Your investments grow tax-deferred. You pay no taxes on earnings or gains year-over-year.
- Withdrawals: All withdrawals—both contributions and earnings—are taxed as ordinary income in retirement.

- High Current Earners: People currently in their highest career-earning years and therefore in a high tax bracket. The deduction provides immediate, significant tax relief.

The Roth IRA: Tax-Free Income in Retirement
The Roth IRA flips the script, operating on the principle of “Pay Tax Now, Tax-Free Later.” It is designed for investors who benefit most from eliminating taxes in the future.
How a Roth IRA Works
- Contributions: You contribute after-tax dollars. No tax deduction is granted on contributions in the year they are made.

- Early Access: You can withdraw your contributions (the principal you put in) at any time, for any reason, without taxes or penalty. This offers a unique emergency fund flexibility not found in a Traditional IRA.
- RMDs (Required Minimum Distributions): Unlike the Traditional IRA, the Roth IRA does not require minimum distributions during the original owner’s lifetime. This allows for maximum tax-free compounding and flexibility in legacy planning.
Who Benefits Most from the Roth IRA?
- Younger Investors: Early-career individuals with low current incomes (low tax bracket now) who have decades of maximum tax-free compounding ahead.
- Expected Higher Tax Bracket in Retirement: Those who anticipate their income or tax rates will be higher in the future.
