Backdoor Roth vs Taxable Investing

A **backdoor Roth** (non-deductible traditional IRA then convert) shelters growth from future taxes when executed correctly. A **taxable brokerage** is flexible but pays annual dividends and capital gains tax along the way.

Step by step

1. Avoid pro-rata

Roll pre-tax IRA balances before backdoor to prevent tax mess.

2. File Form 8606

Document basis on non-deductible contribution.

3. Hold tax-efficient funds

Taxable account favors index ETFs over high turnover.

Backdoor Roth vs taxable
