The Merrill Edge backdoor Roth IRA lets high earners above the 2026 income limits ($165,000 single / $246,000 MFJ) still contribute to a Roth IRA. Merrill Edge processes the conversion at $0 cost, and both your Traditional and Roth IRA balances count toward BofA Preferred Rewards. The 2026 limit is $7,000 ($8,000 if age 50+).
What Is a Backdoor Roth IRA?
The backdoor Roth IRA is a two-step legal strategy for high earners above the Roth IRA income limits:
- Make a non-deductible contribution to a Traditional IRA (no income limit)
- Convert that Traditional IRA balance to a Roth IRA
The result is effectively the same as a direct Roth contribution — after-tax money that grows tax-free — executed in two steps.
2026 Roth IRA Income Limits (Why the Backdoor Is Needed)
| Filing Status | Full Direct Contribution | Partial | Phased Out |
|---|---|---|---|
| Single or Head of Household | Under $150,000 | $150,000–$165,000 | Over $165,000 |
| Married Filing Jointly | Under $236,000 | $236,000–$246,000 | Over $246,000 |
| Married Filing Separately | Under $10,000 | $10,000–$25,000 | Over $25,000 |
If your income exceeds the phaseout ceiling ($165,000 single / $246,000 MFJ), you cannot contribute to a Roth IRA directly. The backdoor Roth is your alternative.
The Pro-Rata Rule: The Critical Complication
If you have existing pre-tax money in any Traditional IRA, SEP-IRA, or SIMPLE IRA, the IRS applies the pro-rata rule to conversions. You cannot selectively convert only your after-tax (non-deductible) dollars.
Example:
- You have $63,000 in pre-tax Traditional IRA contributions
- You add $7,000 in non-deductible contributions (total IRA = $70,000)
- Ratio: 90% pre-tax, 10% after-tax
- When you convert $7,000 to Roth: 90% ($6,300) is taxable — not tax-free
- The backdoor benefit is largely eliminated by the existing pre-tax IRA
Solution: Roll pre-tax IRA funds into your employer’s 401(k) before executing the backdoor Roth. Many 401(k) plans accept incoming rollovers.
If you have no other IRA balances, the pro-rata rule does not apply — your $7,000 non-deductible contribution converts to Roth with zero tax.
2026 Backdoor Roth Contribution Limits
| Detail | Amount |
|---|---|
| Annual limit (under 50) | $7,000 |

| Conversion deadline | December 31, 2026 (for same-year conversion) |
Convert Promptly — Do Not Let It Sit
After making the non-deductible traditional IRA contribution, convert to Roth within days. If the investment earns gains before conversion, those gains are taxable on conversion. The standard advice: contribute and convert in the same week.
Tax Reporting: Form 8606
A backdoor Roth IRA requires you to file IRS Form 8606 with your tax return. This form tracks your non-deductible contributions and the basis in your IRA, ensuring the IRS knows the conversion was from after-tax money. Without Form 8606, you may be double-taxed on conversion.
Step-by-Step: Backdoor Roth IRA at Merrill Edge
Step 1: Open a Merrill Edge Traditional IRA
Go to merrilledge.com → “Open Account” → “Traditional IRA”. The account opens with $0 minimum. If you already have a Merrill Edge Traditional IRA, proceed.
Step 2: Make a Non-Deductible Cash Contribution
Contribute up to $7,000 ($8,000 if age 50+) for 2026. Leave the contribution in cash — do not invest before converting. Note that Merrill Edge does not offer fractional shares, so staying in cash avoids any rounding complications.
Your Traditional IRA balance begins counting toward Preferred Rewards immediately.
Step 3: Convert to Roth IRA at Merrill Edge
At merrilledge.com:
- Log in and navigate to “Retirement Accounts”
- Select your Traditional IRA
- Choose the “Roth Conversion” or “Convert to Roth IRA” option
- Select your Merrill Edge Roth IRA as the destination
- Enter the full cash balance to convert
- Confirm and submit
If you cannot locate the conversion tool, call Merrill Edge at 1-888-637-3343. Merrill representatives can process the conversion over the phone at no charge.
Step 4: Invest in Your Merrill Edge Roth IRA
After conversion, invest the cash in your chosen ETFs or mutual funds. Since Merrill Edge does not offer fractional shares, select ETFs with share prices that work cleanly with your converted balance. iShares ETFs are available at various price points.
BofA Global Research is available inside your Roth IRA to help identify individual stock investments if you research stock picks alongside index funds.
Step 5: File IRS Form 8606
File Form 8606 with your 2026 federal tax return to record the non-deductible contribution and establish IRA basis. Without this form, the IRS may treat your entire conversion as taxable.
Preferred Rewards and the Backdoor Roth
A unique Merrill Edge consideration: both your Traditional IRA and Roth IRA balances count toward Preferred Rewards combined balance.
For a BofA customer near a Preferred Rewards tier threshold, the backdoor Roth IRA effectively has an additional benefit — the Roth balance continues supporting your rewards tier even after conversion.
Example: BofA customer with $30,000 in BofA checking + $18,000 Traditional IRA at Merrill = $48,000 combined (below $50,000 Platinum threshold). After a $7,000 backdoor Roth conversion: Roth IRA balance of $7,000 still counts → $55,000 combined → Platinum tier unlocked.
No other broker creates this kind of rewards-tier benefit from your Roth IRA balance.
Merrill Edge Backdoor Roth Limitations
- No fractional shares: After converting, you need full share prices to invest
- $49.95 ACAT fee: If you ever want to move your Roth IRA to another broker, it costs $49.95 to transfer out
- Online conversion tool availability: May require a phone call depending on account configuration — Schwab and Fidelity have more consistently self-service online conversion tools
Who Should Do the Backdoor Roth at Merrill Edge?
Best fit:
- BofA customers who want both their Traditional and Roth IRA counting toward Preferred Rewards
- Investors already in the Merrill Edge ecosystem who want to keep accounts consolidated
- High earners who use BofA Global Research for equity selection within their Roth
If you’re not a BofA customer, Fidelity or Schwab may be more efficient.
