Step 1: Open a Roth IRA
If you don't already have one, open a Roth IRA at a custodian such as:
Charles Schwab
Fidelity Investments
Vanguard
Step 2: Request the Conversion
Contact your custodian or initiate the transaction online.
You instruct the custodian to transfer assets from:
Traditional IRA → Roth IRA
You can convert:
cash,
mutual funds,
ETFs,
stocks,
or the entire account.
No sale is required if the assets can be transferred "in kind."
Step 3: Pay the Income Tax
The amount converted is generally added to your ordinary taxable income for the year.
For example:
Traditional IRA balance: $2,800,000
Conversion amount: $100,000
If you're in a 24% federal bracket:
Additional federal tax ≈ $24,000
Plus any applicable state taxes
Many advisors prefer paying the tax from a taxable account rather than withholding it from the IRA, allowing more money to remain invested in the Roth.
Step 4: Invest Inside the Roth IRA
Once the assets arrive in the Roth IRA, you invest them according to your allocation strategy.
Future qualified growth and withdrawals are generally tax-free.
Example
Consider the couple from your earlier scenario:
Age 58
Retired
$2.8M Traditional IRA
$900K taxable account
$500K Roth IRA
A planner might evaluate converting:
$50,000
$100,000
$150,000
or more annually
between retirement and the start of:
Social Security,
Medicare-related income surcharges,
and Required Minimum Distributions.
The objective is often to fill up a desired tax bracket (e.g., 22% or 24%) each year without unnecessarily pushing income into much higher brackets.
What makes a good Roth conversion candidate?
Typically someone who:
Has substantial pre-tax retirement assets.
Expects future tax rates to be similar or higher.
Can pay the conversion tax from non-retirement assets.
Wants to reduce future RMDs.
Values tax flexibility later in retirement.
For many affluent retirees, Roth conversions between retirement and age 73 are among the most effective lifetime tax-planning strategies available.
