Taxpayers are limited in the annual amount they can contribute to a Roth IRA. The maximum contribution for 2024 is $7,000 ($8,000 if age 50 or older), but the allowable 2024 contribution for joint-filing taxpayers phases out at an adjusted gross income (AGI) between $230,000 and $240,000 (or an AGI between $0 and $9,999 for married taxpayers filing separately). For unmarried taxpayers, the phase-out is between $146,000 and $161,000. The contribution limits and phase-out limitations are inflation adjusted annually.

However, higher-income taxpayers can circumvent the phase-out income limitations by first making a traditional IRA contribution and then converting it to a Roth IRA, which is commonly referred to as a “back-door Roth IRA.” But, without advance planning, serious pitfalls associated with this maneuver can result in unexpected taxable income.

Converting a traditional Individual Retirement Account (IRA) to a Roth IRA is a financial strategy that many Americans – even those not in the higher tax brackets – consider for its potential long-term tax benefits. However, this decision is not without its complexities and should be approached with a thorough understanding of its implications, benefits, and drawbacks. This article will delve into the process of converting a traditional IRA to a Roth IRA, examining taxability, benefits, pros and cons, age considerations, and other tax-related issues.

Understanding Traditional and Roth IRAs - Before diving into the conversion process, it's essential to understand the fundamental differences between traditional and Roth IRAs. A traditional IRA allows individuals to make pre-tax contributions, reducing their taxable income for the year the contribution is made. The funds in the account grow tax-deferred, but withdrawals are taxed as ordinary income.

Conversely, Roth IRA contributions are made with after-tax dollars, meaning there's no tax deduction for contributions. However, the significant advantage of a Roth IRA is that the earnings grow tax-free, and qualified withdrawals are also tax-free. This feature makes Roth IRAs an attractive option for those who anticipate being in a higher tax bracket during retirement and those creating Roth accounts when they are younger.

The Conversion Process - Converting a traditional IRA to a Roth IRA involves transferring some or all the funds from a traditional IRA into a Roth IRA. When you convert, you must pay income taxes on the amount converted as if it were income for the year. This taxability is a critical consideration, as it can result in a substantial tax bill, depending on the amount converted and your current tax bracket.

Benefits of Converting

Tax-Free Withdrawals: The most significant benefit of a Roth IRA is the ability to withdraw your money tax-free in retirement, or earlier in some cases, providing a hedge against future tax rate increases.

No Required Minimum Distributions (RMDs): Roth IRAs do not require the owner to take minimum distributions starting at age 73, unlike traditional IRAs, allowing for more flexible retirement planning.

Estate Planning Advantages: Roth IRAs can be passed on to heirs, who can also benefit from tax-free withdrawals, making it an effective tool for estate planning. Inherited Roth IRA accounts are subject to the same RMD requirements as inherited traditional IRA accounts, but generally the distributions will be tax free.

Pros and Cons of Converting

Pros:

  • Potential for tax-free growth and withdrawals.

  • No RMDs while the owner is alive, offering more control over your retirement funds.

  • Can provide tax diversification in retirement.

Cons:

  • Upfront tax bill on the converted amount.

  • Conversion could push you into a higher tax bracket for the year.

  • If you are a Medicare beneficiary, the conversion could cause an increase in your Medicare premiums two years later, as the premiums are based on income from the tax return two years prior.

  • Increased adjusted gross income for the year can trigger limitations on other tax benefits that are reduced or eliminated for higher income taxpayers.

  • No reversal – once converted to a Roth IRA, you cannot recharacterize back to a traditional IRA.

Age Considerations - Age plays a significant role in deciding whether to convert a traditional IRA to a Roth IRA. Younger individuals who expect their income (and consequently their tax bracket) to increase over time may benefit more from conversion, as the tax-free withdrawals from a Roth IRA could outweigh the initial tax hit. For older individuals closer to retirement, the decision becomes more nuanced. They must consider whether they have enough time for the benefits of tax-free growth to offset the conversion tax bill.

Other Tax-Related Issues

Non-Deductible Traditional IRAs: Contributions to traditional IRAs can be either pre-tax (tax deductible) or post-tax (not tax deductible). Deductible contributions and earnings are taxable when converted whereas nondeductible contributions are not taxable when converted. When IRA funds are converted, they are considered withdrawn ratably from the taxable and nontaxable portions of the IRA. In addition, all traditional IRAs of a taxpayer are considered one, meaning an IRA with the most nondeductible contributions can’t be singled out for conversion. Thus, a careful analysis is required in advance to establish the taxable percentage when determining how much to convert.      

Conversion Income: The amount converted is added to your taxable income for the year, potentially increasing your tax liability or even pushing you into a higher tax bracket. When considering whether to convert to a Roth IRA, the impact on various tax benefits due to increasing AGI by the taxable conversion amount must be carefully considered. For instance, a conversion may cause the taxpayer to lose part of or all certain tax benefits for the conversion year, like: 

  • American Opportunity Tax Credit

  • Lifetime Learning Tax Credits

  • Earned Income Tax Credit (EIC)

  • Child Tax Credit

  • Saver’s Credit

  • Adoption Credit

  • Higher Education Interest Deduction

  • Medicare B & D Premiums – 2 Years Later

  • Medical Itemized Deductions

  • Miscellaneous Itemized Deductions (in years after 2025)

  • Nontaxable Social Security

  • Favorable Tax Brackets

  • Capital Gains Rates

  • Loss Allowance for Rental Real Estate

Net Investment Income Surtax: Higher-income taxpayers face a potential additional tax related to the Affordable Care Act (health care) provisions: the 3.8% net investment income surtax applies when modified AGI exceeds certain thresholds. A higher AGI due to a Roth conversion could push the taxpayer over the threshold. Also, the additional income from a conversion could negatively impact taxpayers who might otherwise be eligible for credits for health care insurance premiums.

Paying the Tax on a Conversion - Where does the money come from to pay this tax liability on a conversion to a Roth? The taxpayer can pay the liability from other funds or from IRA funds. However, if the tax is paid from IRA funds, those funds are not part of the rollover (conversion) and therefore are not only taxable, but also subject to 10% early withdrawal penalties if the taxpayer is under 59½ at the time of the withdrawal.

Tax Strategy: Strategic tax planning, such as spreading the conversion over several years or timing it during years of lower income, can mitigate the tax impact.

Converting a traditional IRA to a Roth IRA can offer significant benefits, particularly for those who anticipate higher tax rates in retirement or who value the flexibility. However, the decision to convert should not be taken lightly. It requires a careful analysis of your current financial situation, tax implications, and long-term retirement goals. Consulting with this office is highly recommended to navigate the complexities of this decision and to tailor a strategy that best suits your individual needs.
