What Is a Roth IRA Conversion and How Does It Work?
What Is a Roth IRA Conversion?
A Roth IRA conversion is the process of transferring money from a traditional IRA into a Roth IRA. Because traditional IRA funds are generally taxed when withdrawn, converting those funds typically means paying the applicable taxes now. In exchange, you may be able to receive tax-free qualified distributions in retirement, along with other benefits associated with Roth IRAs. (1)
How Does a Roth IRA Work?
A Roth IRA can offer several potential benefits, including:
Tax-free income in retirement: Qualified withdrawals can be tax-free, which may give you greater control over your tax liability during retirement. (1)
Potential tax savings: If your current tax rate is lower than the rate you expect to pay in retirement, paying taxes now may potentially reduce your future tax burden. (1)
Access to contributions: Roth IRA contributions can generally be withdrawn before retirement without taxes or penalties, provided applicable rules are followed. (1)
No lifetime RMDs for the original owner: Roth IRAs do not require the original account owner to take required minimum distributions (RMDs), allowing assets to potentially remain invested and grow tax-free for a longer period. (1)
A potentially tax-free asset for heirs: Roth IRA assets can provide a tax-advantaged inheritance for beneficiaries. (1)
Roth IRA Contribution Eligibility
To contribute directly to a Roth IRA, you generally need earned income and must fall within the income limits established by the IRS. For 2026, the phase-out range for single filers is $153,000 to $168,000. For married couples filing jointly, the phase-out range is $242,000 to $252,000. If your income falls below the applicable range, you may contribute up to the annual limit of $7,500 in 2026, or $8,600 if you are age 50 or older. There is no age limit for making Roth IRA contributions as long as you have qualifying earned income. (2)
If your income is too high to make a direct Roth IRA contribution, you may still be able to move money from a traditional IRA into a Roth IRA through a Roth conversion, sometimes referred to as a “backdoor Roth IRA.” Taxes will generally be due on the amount converted, but qualified future withdrawals from the Roth IRA can be tax-free. (2)
How Does a Roth IRA Conversion Work?
A Roth IRA conversion is permanent. After funds have been converted from a traditional IRA to a Roth IRA, you cannot reverse or undo the transaction. Before converting, it is important to understand the potential tax consequences and broader financial impact. (1)
In most cases, converting pre-tax assets to a Roth IRA creates a taxable event. You pay taxes on the amount converted in the year of the conversion in exchange for the potential to take tax-free qualified distributions later. (1)
A 10% penalty may apply in certain situations when converted assets are withdrawn early. If you are under age 59½ and take a distribution from converted Roth IRA assets before satisfying the applicable five-year holding period, the distribution may be subject to a 10% tax penalty unless an exception applies. The five-year holding period is calculated separately for each Roth conversion you make. (1)
The deadline for a Roth IRA conversion to apply to a particular tax year is December 31. This differs from the deadline for an IRA contribution, which generally follows the tax-filing deadline. (1)
Why Would You Want to Convert to a Roth IRA?
Tax-Free Withdrawals in Retirement
Withdrawals from a traditional IRA or another pre-tax retirement account generally create taxable income. That can include taxes on investment earnings as well as contributions that were previously deducted from your taxable income. (2)
A Roth IRA can provide tax-free qualified withdrawals in retirement, assuming applicable requirements are met. (2)
Leave a Tax-Free Inheritance to Your Heirs
Beneficiaries who inherit a Roth IRA generally must take required distributions, but those withdrawals can be free of federal income tax if the account has been open for at least five years. (2)
No Limits on the Amount You Can Convert
There is no dollar limit on the amount you can convert from a traditional IRA to a Roth IRA. (3)
Flexibility
After five years, converted assets, excluding earnings, can generally be accessed without a penalty for any reason. (3)
What to Consider Before Making a Conversion
Upfront Tax Payment
Depending on the amount you convert, the resulting tax liability could be significant. You may need to have enough money available to cover those taxes, which are generally associated with the calendar year in which the conversion takes place. (3)
You May Not Be Able to Access the Assets Immediately
If you are under age 59½ and withdraw converted funds before the applicable five-year period has passed, you may owe a 10% penalty to the IRS. (3)
You May Face Additional Taxes
Because money converted from a traditional IRA to a Roth IRA is generally included as income for the year of the conversion, the additional income could affect other aspects of your tax situation. For example, high-income earners may become subject to the net investment income tax, taxes on Social Security benefits, and/or higher Medicare surcharges. (3)
The Bottom Line
A Roth IRA conversion can be one strategy to consider if you expect to be in a higher tax bracket later in life. The process involves moving money from a traditional IRA or another eligible retirement account into a Roth IRA, allowing the converted assets to potentially benefit from tax-free growth and qualified tax-free withdrawals. Roth IRAs may also provide benefits such as no lifetime RMDs for the original account owner and the potential to leave tax-advantaged assets to heirs.
However, a Roth conversion can create a tax liability in the year the conversion takes place. Understanding the immediate tax cost, withdrawal rules, potential impact on other taxes, and your long-term retirement strategy is important before making a decision. A qualified financial professional can help you evaluate the potential costs and benefits of a Roth conversion and determine how it may fit into your broader retirement plan.
Frequently Asked Questions About Roth IRA Conversions
What is a Roth IRA conversion?
A Roth IRA conversion involves moving money from a traditional IRA into a Roth IRA. The converted amount is generally taxable in the year of the conversion, but qualified withdrawals from the Roth IRA can be tax-free in the future. (1)
Can I convert a traditional IRA to a Roth IRA if my income is too high to contribute directly?
Yes. Income limits apply to direct Roth IRA contributions, but they do not prevent you from completing a Roth IRA conversion. This strategy is sometimes referred to as a “backdoor Roth IRA.” (2)
How much can I convert to a Roth IRA?
There is no limit on the amount you can convert from a traditional IRA to a Roth IRA. However, the amount you convert generally counts as taxable income for the year of the conversion. (3)
Is a Roth IRA conversion taxable?

Can I undo a Roth IRA conversion?
A Roth IRA conversion is generally irreversible. Once the funds have been converted, the transaction cannot be undone or reversed. (1)
When is the deadline for a Roth IRA conversion?
A Roth IRA conversion must generally be completed by December 31 for it to count toward that tax year. This is different from the deadline for making an IRA contribution. (1)
How long do I have to wait before withdrawing money from a Roth conversion?
Converted funds are subject to a five-year holding period for purposes of avoiding the applicable early-withdrawal penalty. Each Roth conversion has its own five-year holding period. If you are under age 59½, withdrawing converted funds before the applicable period may result in a 10% penalty unless an exception applies. (1)

Qualified Roth IRA withdrawals can be tax-free. Roth IRAs can therefore provide tax-free income in retirement when the applicable requirements are met. (1)

Beneficiaries generally must take required distributions from an inherited Roth IRA, but withdrawals can be free of federal income tax when the account has been open for at least five years. (2)
What should I consider before converting to a Roth IRA?
Consider the tax liability created by the conversion, whether you will need money to cover those taxes, the five-year rules for converted funds, and whether the additional income could affect other taxes or Medicare surcharges. (3)
