Roth vs Traditional IRA Basics for Investors
Traditional IRA contributions may be deductible now with taxable withdrawals later; Roth contributions are after-tax with qualified withdrawals potentially tax-free. Eligibility, limits, and conversions are year-specific. Use this vocabulary guide, then the U.S. accounts desk.
Timing of the tax bite
Traditional IRAs often defer tax: possible deduction going in, ordinary income coming out. Roth IRAs flip the timing: no upfront deduction, potential tax-free qualified withdrawals. Which is “better” depends on rates now vs later, not a slogan.
Limits and phaseouts
Contribution limits, income phaseouts for Roth contributions, and deduction limits if you have a workplace plan change with legislation. Confirm the current IRS numbers before funding.
Conversions
Moving traditional value to Roth usually creates taxable income in the conversion year. “Backdoor” style strategies are paperwork-sensitive and not universal advice.

Simple illustration
Educational numbers only - not your return.
Two investors contribute $1 (simplified). One uses a deductible traditional IRA and pays tax decades later on withdrawal. The other uses a Roth and pays tax on the contribution year wages instead. Future rate assumptions drive the comparison.
Common mistakes
- Contributing to a Roth when income exceeds limits without a valid workaround.
- Ignoring required distribution rules that may apply to traditional accounts.
- Converting a large balance without checking estimated taxes and brackets.
- Treating IRA rules as identical to 401(k) rules.
