Maximizing Retirement Wealth: The ROTH IRA Conversion Tax Strategy

February 15, 2024

As a financial advisor, one of my primary goals is to ensure my clients maximize their retirement wealth while minimizing tax liabilities. One powerful strategy I often recommend is the ROTH IRA conversion. It can be used in a wide variety of financial situations, but I will map out an example of using it for a married couple. In this example, we will look at John and Sue, who are looking to secure their financial future in retirement.

Let's delve into the concept of the ROTH IRA conversion strategy and how it can significantly benefit John and Sue.

Understanding ROTH IRA Conversion

A ROTH IRA conversion involves transferring funds from a Traditional IRA (or other tax-deferred retirement accounts) into a ROTH IRA. This transaction is a taxable event because money is being moved out of a tax-deferred account, but taxes are not withheld from the converted amount. Instead, they are paid out of pocket. Tax-deferred accounts can be wonderful when you have high job income and are trying to lower your tax burden during working years, but they can end up becoming a ticking tax timebomb due to Required Minimum Distributions(RMD) later on in retirement. RMDs would start at age 73 in John's case.

The Scenario: John and Sue's Retirement Plan

John, aged 65, has just retired, while Sue, aged 63, is a homemaker. They reside in California and are keen on optimizing their retirement savings. Here's their financial snapshot:

  • John's Traditional IRA: $2 million
  • Joint investment account: $400,000
  • Social Security Delay: John plans to delay receiving Social Security benefits until age 70.
  • They plan to spend roughly $100,000 every year in retirement

Implementing the ROTH IRA Conversion Strategy

Given their circumstances, the plan is for John to begin converting $100,000 annually from his Traditional IRA to a ROTH IRA starting at age 65 and continuing until age 70.

Benefits and Savings

  1. Tax Efficiency: By gradually converting funds into a ROTH IRA, John and Sue can potentially reduce their future tax liabilities.

  2. From age 65 to 70, their taxable income will be lower due to using withdrawals from their joint investment account to fund those years of retirement. We will take advantage of their lower tax bracket in those years by doing the ROTH conversions then.

  3. Mitigating RMDs: Converting a portion of John's Traditional IRA now helps mitigate Required Minimum Distributions (RMDs) later. A person's RMD is based on the account value of their pre-tax account(s). By reducing the account balance of John's Traditional IRA early on, his RMD amounts are decreased throughout his retirement time. This proactive approach can prevent a significant tax burden for both John and Sue if either of them passes away before the other because the surviving spouse will transition to single filing tax brackets.

  4. Wealth Accumulation: By deferring Social Security benefits until age 70 and strategically executing ROTH IRA conversions, John and Sue stand to accumulate substantial wealth over their retirement years. In this hypothetical scenario, the estimated tax savings could exceed $190,000 throughout their retirement and the potential additional investment growth could exceed $2.8 million over their lifetime due to the converted money growing tax-free in John's ROTH IRA.


The ROTH IRA conversion strategy is a powerful tool for married couples like John and Sue to optimize their retirement wealth while minimizing tax liabilities. By strategically planning conversions and considering factors such as Social Security timing and future tax implications, couples can secure a financially sound retirement.

Again, this is not only a tool for married couples. In my experience, it has been a useful tool in a variety of client scenarios.
