Backdoor Roth IRA: 2 Key Mistakes High-Income Earners Must Avoid

‍

If your income exceeds certain thresholds in 2024, contributing directly to a Roth IRA may not be an option. However, there is still a way for high-income earners to enjoy the benefits of a Roth IRA—the backdoor Roth IRA. While this strategy can be a valuable tool for retirement planning, it’s important to execute it carefully to avoid costly mistakes. In this guide, we’ll cover two critical errors that could derail your backdoor Roth IRA strategy and explain how to avoid them.

‍

What Is a Backdoor Roth IRA?
‍

For those unfamiliar, a backdoor Roth IRA is a workaround that allows high-income earners to contribute to a Roth IRA despite exceeding income limits. Here’s how it works:
‍

1. Make a non-deductible contribution to a traditional IRA—Traditional IRAs have no income limits for non-deductible contributions.
2. Convert that contribution to a Roth IRA—This conversion is permissible regardless of income.
   ‍

While the concept is simple, the execution can be tricky. Let’s dive into the common mistakes to avoid.
‍

Mistake 1: Ignoring the Pro Rata Rule
‍

The pro rata rule can create unexpected tax liabilities if you’re not careful. Here’s how it works:
‍

• The IRS views all your traditional IRA balances as one account.
• When you convert funds to a Roth IRA, the IRS calculates the taxable portion of the conversion based on the ratio of pre-tax to post-tax contributions across all your IRAs.
  ‍

Example of the Pro Rata Rule
‍

Let’s say:

• You have $95,000 in a traditional IRA (all pre-tax).
• You contribute $5,000 (non-deductible) to a new traditional IRA for the backdoor Roth.
  ‍

When you convert the $5,000 to a Roth IRA, the IRS doesn’t see it as entirely non-taxable. Instead, 95% of the conversion ($4,750) will be taxable because 95% of your total IRA balances consist of pre-tax funds.
‍

‍

Solution: Rolling Pre-Tax Funds Into an Employer Plan
‍

To avoid the pro rata rule:

• Roll your pre-tax IRA funds into a 401(k) or 403(b): Employer-sponsored plans are not subject to the pro rata rule, so transferring pre-tax IRA funds into one removes them from consideration.
• Check with your employer: Not all plans allow incoming rollovers, and you typically need to be an active employee.
  ‍

By clearing out pre-tax IRA balances, you can convert non-deductible contributions to a Roth IRA without incurring additional taxes.
‍

Mistake 2: Failing to File IRS Form 8606
‍

Proper documentation is crucial for a backdoor Roth IRA. When you make non-deductible contributions to a traditional IRA, you’ve already paid taxes on that money. To avoid being taxed again during the conversion, you must file IRS Form 8606.
‍

Why Form 8606 Matters
‍

• Tracks non-deductible contributions: This form lets the IRS know you’ve already paid taxes on the converted funds.
• Prevents double taxation: Without this form, the IRS could mistakenly treat your conversion as fully taxable.
  ‍

Filing Tips
‍

• File Form 8606 for every year you make a non-deductible contribution or perform a backdoor Roth conversion.
• It’s a straightforward one-page form but crucial to your tax strategy.
  ‍

Bonus Mistake: Forgetting to Invest Your Roth IRA Funds
‍

Once your money is in the Roth IRA, don’t forget to invest it. Until you choose investments, your funds will sit in cash, missing out on potential growth.
‍

Action Steps
‍

• Choose investments that align with your retirement goals, such as index funds, ETFs, or stocks.
• If you’re unsure, consult a financial advisor or use a platform that provides automated investment options.

‍

Recap: Avoiding Backdoor Roth IRA Pitfalls
‍

To successfully execute a backdoor Roth IRA strategy:
‍

• Avoid the pro rata rule: Roll pre-tax IRA funds into a 401(k) or 403(b) if possible.
• File Form 8606: Ensure you’re not taxed twice on non-deductible contributions.
• Invest your funds: Maximize the growth potential of your Roth IRA.
  ‍

By following these steps, high-income earners can take full advantage of the backdoor Roth IRA strategy, securing tax-advantaged growth for retirement.
