What is Backdoor Roth IRA?
Backdoor Roth IRA is a IRS-sanctioned strategy that allows high-income earners to fund a Roth IRA even when their income exceeds the IRS direct contribution limits.
The process involves two steps:
- Step 1: Contribute to a non-deductible Traditional IRA (no income limit for contributions)
- Step 2: Convert the Traditional IRA to a Roth IRA (no income limit for conversions)
Since you didn't deduct the initial contribution, the conversion is tax-free (only the growth, if any, is taxed). You now have money in a Roth IRA that can grow tax-free and be withdrawn tax-free in retirement.
đĄ Key Insight: Backdoor Roth is explicitly allowed by the IRS. In 2018, the IRS clarified in Notice 2018-54 that this strategy is legal and accepted.
2026 Roth IRA Income Limits
You need Backdoor Roth if your Modified Adjusted Gross Income (MAGI) exceeds these limits:
| Filing Status | Phase-Out Range (2026) | Cannot Contribute Directly |
|---|---|---|
| Single / Head of Household | $150,000 - $165,000 | âĨ $165,000 |
| Married Filing Jointly | $236,000 - $246,000 | âĨ $246,000 |
| Married Filing Separately | $0 - $10,000 | âĨ $10,000 |
Example: If you're single with MAGI of $180,000, you cannot contribute directly to Roth IRA. You must use the Backdoor Roth strategy.
Step-by-Step Backdoor Roth Process (2026)
Step 1: Open a Traditional IRA
Open a Traditional IRA at your preferred brokerage (Fidelity, Vanguard, Schwab, etc.). Choose "non-deductible" as the contribution type.
Step 2: Contribute $7,000 (or $8,000 if 50+)
For 2026, the contribution limit is $7,000 (or $8,000 if you're age 50 or older). Contribute this amount to your Traditional IRA.
â ī¸ Important: Do NOT invest the money yet! Leave it in a money market fund or settlement fund.
Step 3: Wait 1-2 Days for Funds to Settle
Wait for the contribution to "settle" (usually 1-2 business days). This avoids any growth that would be taxed on conversion.
Step 4: Convert to Roth IRA
Log in to your account and request a Traditional IRA â Roth IRA conversion. Select "Convert entire balance." Most brokerages allow this online with 1-2 clicks.
Step 5: File IRS Form 8606
When you file your taxes, complete Form 8606 to report the non-deductible contribution and the conversion. This ensures the IRS knows the contribution was already taxed.
Result: You now have $7,000 in a Roth IRA. It will grow tax-free, and you can withdraw it tax-free in retirement!
Pro-Rata Rule: The Tax Trap to Avoid
The Pro-Rata Rule is the biggest tax trap in Backdoor Roth. It says that when you convert Traditional IRA to Roth, the conversion is not proportional to deductible vs non-deductible contributions.
â ī¸ Warning: If you have any pre-tax money in any Traditional/SIMPLE/SEP IRA, the Pro-Rata Rule applies!
Example of Pro-Rata Tax Trap:
- You have $93,000 in a pre-tax Traditional IRA (from old 401(k) rollover)
- You contribute $7,000 to a new non-deductible Traditional IRA
- Total Traditional IRA balance: $100,000 ($93,000 pre-tax + $7,000 after-tax)
- You convert $7,000 to Roth â 93% is taxable! ($6,510 is taxed as ordinary income)
How to Avoid Pro-Rata Rule:
- Solution 1: Roll your pre-tax Traditional IRA into your current 401(k) (if your 401(k) allows reverse rollovers)
- Solution 2: Convert the entire Traditional IRA balance to Roth in one year (pay taxes now to avoid Pro-Rata forever)
- Solution 3: Only use Backdoor Roth if you have $0 in pre-tax IRAs
Backdoor Roth vs Roth Conversion: What's the Difference?
| Factor | Backdoor Roth | Roth Conversion |
|---|---|---|
| Purpose | Contribute new money to Roth | Convert existing pre-tax money to Roth |
| Tax Due? | Usually $0 (if no growth) | Yes, ordinary income tax on converted amount |
| Best For | High-income earners (cannot contribute directly) | Anyone wanting to move money from Traditional to Roth |
| Pro-Rata Rule? | â Applies (if you have pre-tax IRAs) | â Applies (if you have pre-tax IRAs) |
Frequently Asked Questions
Q: Can I do Backdoor Roth every year?
A: Yes! You can contribute $7,000 (or $8,000 if 50+) every year and convert it. This is a great way to build a large Roth balance over time.
Q: Can my spouse do Backdoor Roth too?
A: Yes! If you're married filing jointly, both spouses can do Backdoor Roth (total $14,000/year, or $16,000 if both 50+). Each spouse needs their own Traditional IRA and Roth IRA.
Q: What if the market drops after I contribute but before I convert?
A: Good news! If your Traditional IRA balance drops (e.g., $7,000 â $6,500), you only convert $6,500. The $500 "loss" is not tax-deductible, but you also don't pay tax on the conversion. Convert as soon as the funds settle to avoid this risk.
