Backdoor Roth IRA: The High Earner's Workaround

If your income exceeds $161,000 single / $240,000 married in 2024, you cannot contribute directly to a Roth IRA. But you can still get there.

The backdoor Roth conversion is explicitly permitted by the IRS and has been used by millions of high earners since 2010. Here is exactly how it works.

Who Should Use This Strategy

Single Filers
MAGI above $161,000 in 2024
Married Filing Jointly
MAGI above $240,000 in 2024
No Existing Pre-Tax IRA
Or you have a plan to deal with the pro-rata rule

Step-by-Step Instructions

1
Open a Traditional IRA if You Do Not Have One
Any major brokerage works: Fidelity, Schwab, Vanguard, or a robo-advisor. The account setup takes about 10 minutes online. You do not need to invest the money immediately.
2
Make a Non-Deductible Contribution
Deposit up to $7,000 ($8,000 if age 50 or older) into the Traditional IRA. When prompted for the tax treatment, choose non-deductible. Do not take a deduction on your tax return. Your after-tax cost basis is $7,000.
3
Wait for the Funds to Clear
Most brokerages require 3 to 7 business days before you can convert. Check your account for a pending hold. Moving too fast can cause the conversion to fail.
4
Convert to Roth IRA
Log into your brokerage and find the Roth conversion option. Select the full Traditional IRA balance and convert it to a Roth IRA. If you contributed in cash and no earnings have accrued, you will owe $0 in taxes on the conversion.
5
Invest the Roth IRA Balance
Now that the money is in your Roth IRA, invest it according to your strategy. Index funds, target-date funds, or individual stocks — whatever fits your plan.
6
File IRS Form 8606 With Your Tax Return
This is the step most people forget. Form 8606 documents your non-deductible contribution and the conversion. Without it, the IRS may treat the conversion as fully taxable when you withdraw in retirement. Keep every Form 8606 you file.

The Pro-Rata Rule: The Catch You Need to Know

The pro-rata rule is the biggest complication for the backdoor Roth. If you have ANY pre-tax money sitting in a Traditional IRA, SEP IRA, or SIMPLE IRA, the IRS treats all of it as one pool when calculating your conversion taxes.

Example:

You have $63,000 in a pre-tax Traditional IRA and you contribute $7,000 (non-deductible). Your total IRA balance is now $70,000. Of that, $7,000 / $70,000 = 10% is after-tax. So only 10% of your conversion is tax-free. You would owe taxes on 90% of the $7,000 you convert.

The most common solution: roll your pre-tax Traditional IRA balance into your employer's 401(k) plan (if your plan accepts rollovers). With $0 in pre-tax IRAs, the pro-rata rule has nothing to apply to, and your backdoor Roth conversion is 100% tax-free.

Mega Backdoor Roth: Even More Room

If your 401(k) plan allows after-tax contributions and in-service withdrawals or in-plan Roth conversions, you can use the mega backdoor Roth to contribute up to $46,000 more per year (2024) into a Roth account.

The total 401(k) limit in 2024 is $69,000. After your $23,000 pre-tax contribution, the remaining $46,000 can be made as after-tax contributions and then converted to Roth. Not all 401(k) plans allow this. Check with your HR department.
