Can You Do a Roth Conversion After 65?
Yes, there is no age limit for Roth conversions. You can execute a Roth conversion after 65, at 75, or even into your 80s and beyond. The IRS does not restrict conversions based on age. What changes at 65 is not your ability to convert, but rather the tax and financial consequences of doing so, those consequences become more complex and interconnected if you don't plan carefully.
At Tax-Free Me, we specialize in implementing proven strategies such as Roth conversions and Social Security optimization to help clients effectively reduce their tax burden during retirement. The real question isn't whether you can convert after 65, it's whether you should, how much you should convert, and when you should do it.
Roth IRA Conversion Tax Implications
When you convert funds from a traditional IRA or 401(k) to a Roth IRA, the amount converted is treated as ordinary income in the year of conversion. The converted amount gets added to your other income for the year. If you earn $60,000 from work and convert $50,000 from a traditional IRA, your taxable income for that year is $110,000. Your tax bracket, Medicare premiums, and Social Security taxation all shift upward based on that $110,000 figure.
How Conversion Amount Affects Your Tax Bracket
The size of your conversion directly determines how much of your income falls into higher tax brackets. Your conversion doesn't stay within a single bracket, it pushes your income upward, and the top portion of your conversion may be taxed at 24%, 32%, or higher, depending on your total income and filing status.
A common mistake is converting too much in a single year and accidentally pushing yourself into a higher bracket for the entire year. The solution is to spread conversions across multiple years or to size each conversion to stay within a specific tax bracket threshold.
Ordinary Income Treatment and Tax Liability
Every dollar you convert is taxed as ordinary income, which means conversions are taxed more heavily than long-term capital gains or qualified dividends. The timing of a conversion relative to other income sources creates your total tax liability. A conversion in a year when you're still working will be taxed more heavily than a conversion in a year when you've retired and have no earned income.
Impact of Roth Conversion on Medicare Premiums
A Roth conversion after 65 can significantly increase your Medicare premiums through Income-Related Monthly Adjustment Amounts, or IRMAA. Medicare uses your modified adjusted gross income (MAGI) from two years prior to determine your premiums. If you convert $100,000 from a traditional IRA in 2026, your 2026 MAGI increases by $100,000. In 2028, when Medicare looks back at your 2026 income, it will charge you higher premiums for Part B and Part D.
The surcharge can be substantial. A couple converting $200,000 could see their combined monthly Medicare premiums increase by $500 to $1,000 or more, depending on their other income sources.
Understanding IRMAA Thresholds
IRMAA thresholds are the income levels at which your Medicare premiums begin to increase. For 2026, the thresholds are:
- Individual filers: $97,000 MAGI
- Married filing jointly: $194,000 MAGI (cms.gov)
Once you exceed these thresholds, you enter a tiered surcharge system with significant jumps in monthly costs. Since Medicare looks back two years, you need to plan your conversions around the income years that will be evaluated.
Planning to Minimize Medicare Surcharges
The strategy is to keep your MAGI below the IRMAA threshold in the years that Medicare will use to calculate your premiums. If you're 65 in 2026 and enrolling in Medicare, the IRS will use your 2024 income to set your 2026 premiums. Your 2025 income determines your 2027 premiums. This two-year lag creates a planning window where you can execute conversions in years when your other income is low.
Five-Year Rule for Roth Conversions
The five-year rule is actually two separate rules that apply to different situations. The first five-year rule applies to earnings in your Roth IRA. If you convert funds to a Roth and those funds generate investment gains, you cannot withdraw those earnings tax-free until you've held the Roth for five tax years and meet other conditions (age 59½, disability, death, or first-time home purchase up to $10,000) (irs.gov).
The second five-year rule applies specifically to conversions. When you convert a traditional IRA to a Roth, that converted amount is subject to a five-year holding period before you can withdraw it penalty-free if you're under 59½. After 65, this rule is less relevant because you're already past 59½, so you can withdraw converted amounts penalty-free immediately. However, the five-year rule for earnings still applies.
The practical implication: converted funds can be withdrawn tax-free and penalty-free after conversion if you're over 59½. Earnings on those converted funds must remain in the Roth for five years from the conversion date before they can be withdrawn tax-free.
Roth Conversion vs. Traditional IRA Withdrawal
The choice between a Roth conversion and a traditional IRA withdrawal comes down to timing and tax management. A traditional IRA withdrawal removes funds from your tax-deferred account and you pay income tax on the full amount withdrawn. A Roth conversion removes funds from your traditional IRA, you pay income tax on the full amount converted, and the funds then grow tax-free in a Roth IRA.
The difference is what happens next. With a withdrawal, you have the cash but no ongoing tax-deferred or tax-free growth. With a conversion, the funds continue to grow inside a Roth, and all future growth is tax-free. If you don't need the cash and you want to continue building retirement savings with tax-free growth, a conversion is often the better option.
Required Minimum Distributions and Conversion Strategy
Required Minimum Distributions, or RMDs, are mandatory annual withdrawals from traditional IRAs and 401(k)s that begin at age 73 (irs.gov). These distributions are fully taxable as ordinary income. A Roth conversion after 65 interacts with RMD planning in critical ways. If you have a large traditional IRA balance, your future RMDs will be substantial. A conversion before your RMDs begin can reduce the size of your future RMDs by moving funds out of the traditional account and into a Roth, where no RMDs are required during your lifetime.
How RMDs Interact With Conversion Sizing
Your RMD is calculated by dividing your traditional IRA balance on December 31 of the prior year by a life expectancy factor from the IRS table. If you convert $100,000 before your first RMD year, your RMD calculation is based on a lower balance, which reduces the amount you must withdraw and the taxes you owe. If you're 64 and your first RMD year will be at 73, you have a window to execute conversions before those mandatory withdrawals begin.
The trade-off is that you pay taxes on the conversion today instead of paying taxes on the RMD withdrawal later. Whether this makes sense depends on your tax bracket today versus your expected tax bracket when RMDs would begin, and on whether you can afford to pay the conversion taxes without withdrawing from your retirement accounts.
Timing Conversions Around RMD Withdrawals
Once your RMDs begin, the IRS requires that you take the full RMD for the year before you can do a conversion. You cannot use a conversion to avoid or reduce your RMD in the same calendar year. However, you can time conversions strategically relative to your RMD by taking your RMD early in the year, then executing a conversion later in the year.
The key is to plan the combination of RMDs and conversions together, not to treat them as separate decisions. Your conversion strategy should account for the RMDs you'll be required to take.
Estate Planning and Beneficiary Benefits
A Roth conversion after 65 has significant estate planning implications. When you pass away, your heirs inherit your accounts. Traditional IRA and 401(k) beneficiaries are required to withdraw and pay income tax on inherited funds. In most cases, the funds must be withdrawn within 10 years, and the beneficiary pays income tax on every dollar withdrawn.
Roth IRA beneficiaries inherit tax-free growth. They must take distributions from the inherited Roth, but those distributions are tax-free. By converting a portion of your traditional IRA to a Roth before you pass away, you shift the tax burden from your heirs to yourself. Your heirs inherit a larger Roth balance that grows tax-free and passes to them tax-free. This is particularly valuable if you have substantial assets and want to maximize the wealth you pass to your family.
Executing a Roth conversion after 65 requires careful coordination with your overall retirement income plan. The tax implications, Medicare premium impact, and interaction with RMDs and Social Security are complex and interconnected. At Tax-Free Me, we specialize in mapping out these relationships and structuring conversions that minimize your lifetime tax burden while protecting your Medicare eligibility and Social Security benefits. If you're considering a conversion, work with a financial advisor who understands how all these pieces fit together.
Frequently Asked Questions
Does a Roth conversion after 65 affect my Medicare premiums?
Yes. Roth conversions increase your modified adjusted gross income (MAGI), which can trigger IRMAA surcharges on Medicare Part B and Part D premiums. The impact depends on your MAGI threshold and how much you convert. Planning conversion size and timing carefully can minimize this effect. Consider spreading conversions across multiple years or coordinating with other income sources to stay below IRMAA thresholds.
What is the five-year rule for Roth conversions?
The five-year rule requires you to wait five tax years from the conversion date before withdrawing converted funds penalty-free. If you withdraw converted amounts before five years pass, you may face a 10% early withdrawal penalty, even after age 59½. Each conversion has its own five-year clock, so multiple conversions require tracking separate timelines. This rule does not apply to contributions, only conversions.
How much tax will I owe on a Roth conversion after 65?
Tax owed equals the converted amount multiplied by your marginal tax rate. A $50,000 conversion in the 22% tax bracket costs approximately $11,000 in federal taxes. However, the conversion also increases your MAGI, potentially pushing you into a higher bracket or triggering IRMAA surcharges. The actual tax cost depends on your total income, filing status, and other deductions. Work with a tax professional to model your specific situation.
Should I do a Roth conversion if I'm still working at 65?
Working at 65 can complicate conversions because your earned income increases your tax bracket and MAGI. However, conversions may still make sense if you expect lower income in future years or want to build tax-free assets before RMDs begin. The decision depends on your total compensation, employer plan rules, and long-term retirement income goals. A comprehensive analysis comparing your current versus projected future tax brackets is essential.
