Older gentleman reviewing tax paperwork

TL;DR: Backdoor Roth IRA conversions let high-income Maryland residents access tax-free Roth accounts despite income limits. While legal and valuable, they involve IRS rules (like pro-rata treatment) and Maryland tax implications—so professional guidance is essential.

Why Use One?

  • Tax-free growth on investments.
  • No RMDs, offering greater flexibility in retirement.
  • Estate planning benefits through more tax-efficient wealth transfer.

If you’re a Maryland resident earning too much to contribute directly to a Roth IRA, you might feel like the door to tax-free retirement savings has closed. However, there’s still a way to make your retirement dollars work smarter.

It’s called a Backdoor Roth IRA conversion.

This is a little-known yet completely legal strategy designed to reopen that door for high-income earners. It uses the mechanics of the tax code to your advantage, especially when traditional contribution limits shut you out.

Join us as we cover what a Backdoor Roth IRA conversion really is, how it works specifically for Maryland residents, and what rules, deadlines, and potential pitfalls you need to be aware of.

What is a Backdoor Roth IRA Conversion?

Typically, if your modified adjusted gross income (MAGI) is too high, you’re barred fromcontributing directly to a Roth IRA. According to the most recent data available, the direct Roth IRA contribution phase-out begins at around $146,000 for single filers and $230,000 for married couples filing jointly.

This makes many Maryland professionals, such as doctors, lawyers, consultants, or D.C. federal employees, ineligible for direct Roth contributions.

A Backdoor Roth IRA conversion offers a workaround:

  1. You make a non-deductible contribution to a Traditional IRA. Since there are no income limits for non-deductible IRA contributions, anyone can do this.
  2. Then, you convert those funds to a Roth IRA. Because the contribution was made with after-tax dollars, little to no tax is owed at conversion.

Backdoor Roth IRAs are particularly beneficial for:

  • High-income professionals in Maryland’s biotech, legal, medical, and federal sectors.
  • Self-employed business owners who want more tax-advantaged retirement options.
  • Dual-income households in Howard or Anne Arundel counties who consistently exceed the Roth income thresholds.

Is a Backdoor Roth IRA a Conversion or a Recharacterization?

This is a common point of confusion. A Backdoor Roth IRA is a conversion, not a recharacterization.

  • A conversion involves intentionally moving funds from a Traditional IRA to a Roth IRA.
  • A recharacterization, on the other hand, refers to undoing or reversing a Roth contribution or conversion. This used to be more common, but has been restricted since 2018.

Why Use a Backdoor Roth IRA?

For many Maryland residents with high incomes, traditional Roth IRAs are out of reach. But with a Backdoor Roth, you can still access these long-term benefits:

1. Tax-Free Growth

Once your money is in a Roth IRA, all growth is tax-free. That includes interest, dividends, and capital gains.

2. No Required Minimum Distributions (RMDs)

Unlike Traditional IRAs, Roth IRAs have no RMDs during your lifetime. This gives you complete control over when you tap into your account. For Maryland retirees planning around Social Security timing or state income taxes, this flexibility is priceless.

3. Strategic Estate Planning

Roth IRAs are also a powerful estate planning tool. Since they grow tax-free and aren’t subject to RMDs, they can be passed on to heirs in a more tax-efficient way than Traditional IRAs.

Downsides and Risks of Backdoor Roth IRAs

While a Backdoor Roth IRA conversion can be a savvy tax strategy, it’s not without complications.

Keep in mind that this method may come with:

  • Tax complexity: Pro-rata rule, reporting requirements.
  • Unexpected tax liability: Especially if other IRAs exist.
  • Step transaction risk if done too quickly.
  • Potential audit triggers.

That being said, there are some instances when a Backdoor Roth IRA wouldn’t be the best fit. Such as in these scenarios:

  • You already have large pre-tax IRA balances.
  • You’re close to retirement and won’t benefit from long-term tax-free growth.
  • You cannot afford to pay conversion taxes from non-retirement funds.
  • You’re unsure of staying in Maryland or expect lower tax rates elsewhere.

Understanding the Backdoor Roth IRA Conversion Rules

Like with any tax strategy, it’s important to understand the Backdoor Roth IRA conversion rules that can affect the outcome. This is especially true for Maryland residents who may face added complexity with state tax treatment and documentation.

Pro-Rata & Aggregation Rules

The pro-rata and aggregation rules go hand in hand. The former accounts for how the IRS treats all your IRA balances as one big pool. In other words, you can’t pick and choose only your after-tax contributions to be converted.

The aggregation rule means the IRS views all Traditional IRAs, SEP IRAs, and SIMPLE IRAs as one combined account.

Backdoor Roth IRA Conversion Deadline

The contribution portion of a Backdoor Roth IRA must follow the same timeline as traditional IRA contributions:

  • For the 2025 tax year, contributions must be made by Tax Day—April 15, 2026 (or the IRS filing deadline, if extended).
  • This deadline applies regardless of whether you file for an extension.

One-Rollover-Per-Year Rule

This rule limits you to one IRA-to-IRA rollover within a 12-month period. Direct transfers (trustee-to-trustee) are not subject to this limitation.

Most backdoor Roth conversions are done as conversions, not rollovers, so they are not limited by this rule.

Backdoor Roth IRA Conversion Limits

While the backdoor strategybypasses income limits, it does not bypass the annual contribution limitsset by the IRS:

  • $7,000 for individuals under age 50
  • $8,000 for individuals age 50 or older (includes a $1,000 catch-up contribution)

Professional Help for Backdoor Roth IRA Conversions

As of 2025, the Backdoor Roth IRA conversion remains fully legal and available, despite previous legislative attempts like the Build Back Better Act, which sought to eliminate it but ultimately did not pass.

However, tax laws can change quickly. It’s best to stay informed and verify the rules annually with a trusted tax professional.

These professionals can also help you navigate the pro-rata rule, file forms correctly, optimize your timing, and ensure compliance on both your federal and Maryland state returns.
