Frequently Asked Questions

What is a backdoor Roth IRA?

A backdoor Roth IRA is a legal strategy that allows high-income earners (like physicians who exceed the Roth IRA income limit of $161,000 single / $240,000 married in 2026) to contribute to a Roth IRA by first making a non-deductible Traditional IRA contribution and then converting it to Roth. The result: tax-free growth and tax-free withdrawals in retirement on up to $7,000 per year per person.

Is the backdoor Roth IRA legal?

Yes, it is completely legal. The IRS has repeatedly acknowledged this strategy, and it has been widely used since the income limit on Roth conversions was removed in 2010. While Congress has proposed eliminating it in past legislation (Build Back Better Act), it remains legal as of 2026. Financial advisors and CPAs routinely recommend it for high-income professionals.

What is the pro-rata rule and how does it affect physicians?

The pro-rata rule requires that if you have any pre-tax Traditional IRA funds, your Roth conversion is taxed proportionally based on the ratio of pre-tax to after-tax funds across ALL your Traditional IRAs. For example, if you have $93,000 in a rollover IRA (pre-tax) and contribute $7,000 (after-tax) for a backdoor Roth, only 7% of your conversion would be tax-free. Solution: roll any pre-tax IRA funds into your 401(k) before executing the backdoor Roth.

How much can I contribute to a backdoor Roth IRA in 2026?

$7,000 per person ($7,500 if age 50+). If married, both spouses can each do $7,000 for a combined $14,000 per year. While the annual amount seems small, $14,000/year invested in a Roth for 25 years at 8% returns grows to approximately $1.1 million in completely tax-free money.

What is a mega backdoor Roth?

A mega backdoor Roth allows after-tax 401(k) contributions (above the $23,500 pre-tax limit) to be converted to Roth — up to an additional $46,000 in 2026. This requires your employer 401(k) plan to allow both after-tax contributions and in-plan Roth conversions. Not all plans offer this, but it is increasingly common at large healthcare systems. Combined with the standard backdoor Roth, you could contribute up to $76,500 to Roth accounts annually.

Step-by-step guide to the backdoor Roth IRA for high-income physicians. Avoid the pro-rata trap, understand the mega backdoor option, and maximize tax-free retirement savings.

Key Takeaways

The backdoor Roth IRA lets physicians bypass the $240,000 income limit and contribute $7,000/year ($14,000 for couples) to a Roth IRA
It is a 3-step process: contribute to Traditional IRA → convert to Roth → report on Form 8606
The pro-rata rule can trigger unexpected taxes — roll any pre-tax IRA money into your 401(k) first
$14,000/year invested for 25 years at 8% grows to ~$1.1 million in TAX-FREE money
The mega backdoor Roth adds up to $46,000 more in Roth space if your 401(k) plan allows it

If you earn over $240,000 (married filing jointly) or $161,000 (single) in 2026, you cannot contribute directly to a Roth IRA. But you can still get money into one through the backdoor Roth IRA strategy — a perfectly legal workaround that every high-income physician should use.

Step-by-Step: How to Execute a Backdoor Roth IRA

Step 1: Verify You Have No Pre-Tax IRA Funds

Check all your Traditional IRA, SEP-IRA, and SIMPLE IRA accounts. If any contain pre-tax funds (prior deductible contributions or rollovers), you must roll those into your 401(k) or 403(b) before proceeding. This avoids the pro-rata rule tax trap.

Step 2: Contribute to a Traditional IRA (Non-Deductible)

Open a Traditional IRA (if you do not already have one) and contribute $7,000 ($7,500 if 50+). Do NOT take a tax deduction for this contribution — it must be non-deductible since you have a workplace retirement plan and exceed the income limit for deductible Traditional IRA contributions.

Step 3: Wait Briefly, Then Convert to Roth

Convert the entire Traditional IRA balance to your Roth IRA. Some advisors recommend waiting 1-2 days between contribution and conversion to avoid the appearance of a "step transaction," though the IRS has never ruled against same-day conversions. Most brokerage firms (Fidelity, Vanguard, Schwab) make this a simple online process.

Step 4: Invest the Roth IRA Funds

Once the money is in your Roth IRA, invest it according to your investment portfolio strategy. The funds will grow tax-free and can be withdrawn tax-free in retirement.

Step 5: Report on Your Tax Return (Form 8606)

File IRS Form 8606 with your tax return to report the non-deductible Traditional IRA contribution and the Roth conversion. Your tax software (or CPA) will handle this, but make sure it is not missed — failing to file Form 8606 can result in a $50 penalty and confusion in future years.

The Pro-Rata Rule: The Trap Most Physicians Fall Into

The pro-rata rule is the most common mistake physicians make with backdoor Roth conversions. Here is how it works:

If you have any pre-tax money in any Traditional IRA (including SEP-IRA or SIMPLE IRA), the IRS treats ALL your Traditional IRA accounts as one pool when calculating the tax on your conversion. The conversion is taxed proportionally based on the pre-tax percentage of the total pool.

Scenario	Pre-Tax IRA	New Contribution	Tax-Free %	Tax on $7K Conversion
Clean (no pre-tax)	$0	$7,000	100%	$0
Small rollover IRA	$21,000	$7,000	25%	~$1,940 (at 37%)
Large rollover IRA	$93,000	$7,000	7%	~$2,405 (at 37%)

The fix: Roll any pre-tax IRA funds into your 401(k) or 403(b) before December 31 of the year you do the conversion. Most employer plans accept incoming rollovers. This zeros out your pre-tax IRA balance and makes the entire conversion tax-free.

Mega Backdoor Roth: The Supercharged Version

If your employer's 401(k) plan allows after-tax contributions AND in-plan Roth conversions (or in-service withdrawals to a Roth IRA), you can contribute up to an additional $46,000 beyond the standard $23,500 employee limit. This is the mega backdoor Roth.

Combined contribution potential in 2026:

Account	Amount	Tax Treatment
401(k) pre-tax/Roth	$23,500	Tax-deferred or Roth
Mega backdoor Roth (401k)	Up to $46,000	Roth (tax-free growth)
Backdoor Roth IRA	$7,000	Roth (tax-free growth)
Total Roth potential	Up to $76,500	Tax-free growth forever
