The Backdoor Roth IRA: How High Earners Bypass the Income Limit
Roth IRA income limits cut off direct contributions above $168,000 for singles. The backdoor method works legally for any income level. Here is the step-by-step.

Quick answer
The backdoor Roth IRA is a two-step process: contribute after-tax dollars to a Traditional IRA (no income limit on contributions, just deductibility), then convert that balance to a Roth IRA. In 2026, you can move up to $7,500 ($8,600 if 50+) through this strategy. The pro-rata rule complicates the math if you have existing pre-tax IRA balances — the conversion becomes partially taxable based on the ratio of pre-tax to after-tax IRA funds across all your IRAs. The cleanest execution: zero pre-tax IRA balances before contributing.

hello@workainow.comWhy high earners cannot contribute directly to a Roth IRA
The Roth IRA is one of the most tax-efficient accounts in existence — contributions grow tax-free and withdrawals in retirement are completely tax-free. Congress designed income limits to restrict this benefit to lower and middle-income earners: in 2026, single filers with MAGI above $168,000 and married filers above $252,000 cannot contribute directly to a Roth IRA.
There is, however, no income limit on converting a Traditional IRA to a Roth IRA — a rule that has existed since 2010. This creates the backdoor Roth: contribute to a Traditional IRA (where there is no income limit on contributions, only on deductibility), then immediately convert that balance to Roth.
The IRS is aware of this strategy and has not acted to prohibit it. The standard interpretation by tax professionals is that it is legally sound, though Congress could theoretically close it in future legislation. As of 2026, it remains available.
The step-by-step execution
Step 1: Confirm you have no existing pre-tax IRA balances across all Traditional, SEP, and SIMPLE IRA accounts. If you do, the pro-rata rule applies and the conversion becomes partially taxable (more on this below). Ideally start this with zero pre-tax IRA balances.
Step 2: Open a Traditional IRA if you do not already have one. Contribute the annual limit — $7,500 in 2026 ($8,600 if age 50 or older). Do not take a deduction for this contribution (it is non-deductible since you are a high earner above the deductibility phase-out range). Record this on IRS Form 8606.
Step 3: Convert the Traditional IRA to a Roth IRA immediately — within days if possible, before any investment gains accumulate (which would otherwise create a small taxable amount at conversion). Most brokerages have a simple online conversion process. Report the conversion on Form 8606 when you file your taxes.
The pro-rata rule: the most common mistake
The pro-rata rule requires that when you convert IRA funds to Roth, the taxable and non-taxable portions are calculated based on all your Traditional, SEP, and SIMPLE IRA balances — not just the account you are converting.
Example: You have $93,500 in a pre-tax Traditional IRA from previous employer rollovers, and you contribute $6,500 in after-tax dollars and then convert. Your total IRA balance is $100,000. The after-tax portion is 6.5% of the total. Therefore, only 6.5% of the conversion is tax-free — the remaining 93.5% is taxable at ordinary income rates. The $6,500 you intended to move tax-free generates a large and unexpected tax bill.
The solution: roll pre-tax IRA balances into a current employer's 401(k) plan before executing the backdoor Roth. Many 401(k) plans accept incoming rollovers. Once the pre-tax balance moves to the 401(k), it is no longer included in the pro-rata calculation, and the backdoor conversion proceeds cleanly.
