Individual Retirement Accounts (IRAs) are essential tax-advantaged tools for US wealth building. Deciding whether to place your investment contributions into a Roth IRA or a Traditional IRA centers on your tax bracket today versus your anticipated tax bracket in retirement.
Direct Comparison Matrix

|---|---|---|

| Required Minimum Distributions (RMDs) | None during original owner’s lifetime | Mandatory starting at age 73 or 75 |
| Early Contribution Withdrawals | Contributions can be withdrawn at any time penalty- and tax-free | Subject to 10% penalty + income taxes before age 59½ |
The Backdoor Roth IRA Strategy
If your Modified Adjusted Gross Income exceeds IRS limits for direct Roth contributions, you can utilize the Backdoor Roth IRA: make a non-deductible contribution to a Traditional IRA, then immediately convert it to a Roth IRA, shielding future compounding from taxes.
Pair your IRA setup with your employer’s 401(k) contribution plan and populate your accounts with broad-market index funds and ETFs.
