Your IRA Could Become a Future Tax Challenge. Here's Why RMD Planning and Roth Conversions Are Increasingly Important
Written By Bret Mooney
One of the most common planning conversations today centers around large traditional Individual Retirement Accounts (IRAs) and what they may mean for retirement income, taxes, and legacy planning.
For many households, retirement accounts have become one of their largest assets. While that often reflects years of disciplined saving, it also introduces an important consideration: tax deferred accounts do not stay tax deferred forever.
As Required Minimum Distributions (RMDs) begin under current IRS rules, large IRA balances may create tax implications not only for retirees, but also for the wealth they eventually pass on.
Large IRA Balances and the Tax Pressure That Can Build Over Time
Traditional IRAs and 401(k)s allow for tax deferred growth, but withdrawals are generally taxed as ordinary income.
Once RMDs begin, retirees typically lose flexibility over the timing and amount of required withdrawals. For larger retirement accounts, these distributions can increase taxable income and may contribute to:
Higher marginal tax brackets
Increased Medicare Income Related Monthly Adjustment Amount (IRMAA) premiums
Greater taxation of Social Security benefits
Reduced flexibility in managing annual income
According to IRS guidance, RMDs must generally be withdrawn annually once an individual reaches the applicable RMD age. Because these distributions are taxable in most situations, they can affect multiple areas of a retiree's financial picture.
The Legacy Planning Connection
Many families focus on how retirement assets will support their own retirement, but fewer consider how those assets may affect future generations.
Under current rules, many non spouse beneficiaries must distribute inherited IRAs within 10 years. Those distributions are generally taxable to the beneficiary.
For heirs already in peak earning years, inherited IRA distributions may create additional taxable income, potentially reducing the after tax value of inherited assets.
As a result, retirement income planning and legacy planning are often more connected than many investors realize.
Why Roth Conversions Continue to Gain Attention
A Roth conversion involves moving assets from a traditional IRA into a Roth IRA and paying taxes on the converted amount.
While this creates a current tax obligation, it may provide greater flexibility later. As discussed in VestGen Wealth Partners' article, Your Guide to Roth Conversions in 2026, Roth conversions are often evaluated as part of a broader tax planning strategy rather than a standalone decision.
Depending on individual circumstances, Roth conversions may help support:
Reduced future RMD exposure
Greater tax diversification
Increased retirement income flexibility
More efficient wealth transfer opportunities
Because Roth IRAs are not currently subject to lifetime RMDs for the original owner, they may offer additional planning flexibility.
Final Thoughts
For many households, the question is no longer simply how much has been saved for retirement, but how those assets will be taxed, distributed, and ultimately transferred.
Thoughtful management of Required Minimum Distributions (RMDs), Roth conversion strategies, and beneficiary planning may help create greater flexibility over time. Evaluating these areas together can support a more coordinated approach to retirement income, tax planning, and long term wealth transfer goals.
