On a recent episode of the Money Guy Show titled “Van Life Millionaires Are Leaving Millions on the Table,” co-host Bo Hanson discussed a couple, Robert and Carrie, who had been diligent savers and had built a healthy portfolio. However, when their planner ran the numbers forward, they discovered a potential tax bomb waiting for them in retirement.
The key issue facing couples with large traditional 401(k) and IRA balances is the ‘tax bomb’ that occurs at age 75 when Required Minimum Distributions (RMDs) begin. This can result in a significant jump in tax brackets, potentially going from 12% to 32% or higher. To mitigate this tax burden, strategic Roth conversions between retirement and age 75 can save individuals $1.3 million in taxes and add $3.5 million in assets over a lifetime.
Hanson warned that many savers underestimate the impact of RMDs on their retirement income. Traditional 401(k) and IRA balances are pre-tax, meaning that every dollar withdrawn is taxed as ordinary income. Once individuals reach age 75, the IRS mandates RMDs, forcing them to withdraw a certain percentage of their balance each year, which can push them into higher tax brackets.
To illustrate the potential impact, Hanson provided an example of a couple with $1.5 million in a traditional 401(k) at age 45. By age 75, their balance could reach $6 million to $8 million, resulting in significant RMDs that could push them into higher tax brackets.
The solution lies in executing strategic Roth conversions between retirement and the start of RMDs. By converting funds at today’s lower tax brackets, individuals can avoid higher tax rates in retirement and pass on tax-free assets to their heirs. This can result in significant tax savings and asset accumulation over time.
It is crucial to consider the variable of marginal tax brackets when deciding on Roth conversions. If individuals are projected to retire into a lower tax bracket than they currently live in, conversions may not be beneficial. However, if their projected RMD bracket is higher than their conversion-year bracket, converting at the lower rate can provide significant tax savings.
In conclusion, it is essential for individuals to assess their tax strategies and consider implementing Roth conversions to optimize their retirement income and minimize tax liabilities. By planning ahead and taking proactive steps, individuals can ensure a more secure financial future in retirement.
