Quick Answer
A backdoor Roth IRA lets high earners contribute to a Roth IRA by making a non-deductible traditional IRA contribution and immediately converting it. In 2026, single filers earning over $153,000 and married couples over $228,000 can use this strategy to bypass Roth IRA income limits.

How the backdoor Roth IRA strategy works
A backdoor Roth IRA is a two-step process that allows high earners to contribute to a Roth IRA despite exceeding income limits. In 2026, direct Roth IRA contributions phase out for single filers earning $138,000-$153,000 and married filing jointly earning $218,000-$228,000.
The strategy works by exploiting a gap in tax law: while there are income limits for Roth IRA contributions, there are no income limits for converting traditional IRA funds to a Roth IRA.
Step-by-step backdoor Roth process
Step 1: Make a non-deductible contribution to a traditional IRA. In 2026, you can contribute up to $7,000 ($8,000 if age 50+) regardless of income level.
Step 2: Immediately convert the traditional IRA funds to a Roth IRA. Since you made a non-deductible contribution, there's minimal or no tax on the conversion.
Example: $200,000 earner using backdoor Roth
Sarah earns $200,000 as a single filer in 2026. She's above the $153,000 Roth IRA limit but wants tax-free retirement growth.
If Sarah's traditional IRA grows to $7,050 before conversion, she pays taxes on the $50 gain only.
Key factors that affect backdoor Roth success
The pro-rata rule trap
This is where many people get caught. If you have existing traditional IRA funds with pre-tax dollars, the IRS requires you to convert proportionally from all accounts.
Example: You have $93,000 in pre-tax traditional IRA funds and make a $7,000 non-deductible contribution (total: $100,000). When you convert $7,000:
This significantly reduces the backdoor Roth benefit.
What you should do
1. Check for existing traditional IRA balances before attempting backdoor Roth
2. Consider rolling old 401(k)s into your current employer's plan instead of an IRA to avoid pro-rata issues
3. Execute the conversion within days of the contribution to minimize growth
4. File Form 8606 to track your non-deductible IRA basis
5. Use our return scanner to ensure you're not missing other high-earner strategies
Key takeaway: Backdoor Roth IRAs let high earners contribute $7,000 annually to a Roth IRA regardless of income, but existing traditional IRA balances can complicate the strategy through the pro-rata rule.

Best for people with complex retirement account situations who need to navigate the pro-rata rule
Navigating backdoor Roth with existing accounts
If you have existing traditional IRA, SEP-IRA, or SIMPLE IRA accounts, the backdoor Roth becomes more complex due to the pro-rata rule. The IRS treats all your traditional-style IRAs as one big account for conversion purposes.
Strategic account consolidation
Before executing a backdoor Roth, consider these moves:
Rollover strategy: Move existing traditional IRA funds into your current employer's 401(k). Most plans accept rollovers, and this removes funds from the pro-rata calculation.
Example: James has $45,000 in a traditional IRA from an old job and earns $180,000. Instead of a backdoor Roth:
1. He rolls the $45,000 into his current 401(k)
2. Now his traditional IRA balance is $0
3. He can execute a clean backdoor Roth with no pro-rata complications
Timing considerations for complex situations
The pro-rata rule looks at your IRA balances on December 31st of the conversion year. This creates planning opportunities:
State tax complications
Several states don't follow federal Roth conversion rules, creating additional complexity:
Key takeaway: Existing retirement accounts don't prevent backdoor Roth strategies, but they require careful planning and potentially rolling funds into employer plans first.

Backdoor Roth for retirees and near-retirees
Even in retirement, backdoor Roth conversions can be valuable for estate planning and tax diversification. Unlike regular IRA contributions, there's no age limit for backdoor Roth strategies.
Estate planning benefits
Roth IRAs have significant advantages for wealth transfer:
Example: Margaret, 72, has $500,000 in traditional IRAs and takes required distributions. She also has $200,000 in taxable investments earning dividends. By using backdoor Roth ($7,000 annually) and regular Roth conversions, she gradually shifts wealth to tax-free accounts for her heirs.
Managing retirement tax brackets
Retirees often have lower tax brackets than their working years, making Roth conversions more attractive:
Coordination with other strategies
Backdoor Roth fits into broader retirement tax planning:
Qualified Charitable Distribution (QCD): Use QCDs from traditional IRAs to satisfy RMDs while keeping taxable income low for larger Roth conversions
Health Savings Account maximization: If you're still eligible for HSA contributions, prioritize those over backdoor Roth for the triple tax advantage
Key takeaway: Retirees can use backdoor Roth strategies indefinitely for estate planning, often at lower tax brackets than during their working years.
