The order you tap your accounts can change your lifetime tax bill dramatically. Here's how to sequence withdrawals wisely.
What Is a Tax-Efficient Withdrawal Strategy?
A tax-efficient withdrawal strategy decides which accounts to spend from, and in what order, to minimize taxes across your whole retirement, not just one year. Retirees typically hold three account types: taxable (brokerage), tax-deferred (traditional IRA and 401(k)), and tax-free (Roth). The classic sequence spends taxable accounts first, then tax-deferred, then Roth last, so tax-free money compounds longest. But the most effective plans blend buckets each year, drawing enough from tax-deferred accounts to fill low brackets while preserving Roth dollars. The right sequence depends on your balances, bracket, and Required Minimum Distribution timing, and it usually shifts year to year.
How Do Roth Conversions Fit the Strategy?
The window between retiring and age 73 is the strategic heart of withdrawal planning. In these low-income years, you can convert traditional IRA funds to Roth at the 10% or 12% rate, deliberately filling those low brackets. This shrinks the traditional balance that will later trigger large Required Minimum Distributions, smoothing your income and tax rate over decades. Done well, it prevents a tax spike at 73 and reduces the taxable portion of your Social Security later. The key is sizing each conversion to avoid jumping a bracket or crossing a Medicare IRMAA threshold, which calls for a year-by-year plan rather than guesswork.
How Does Medicare Shape Your Withdrawal Plan?
Every withdrawal decision affects your modified adjusted gross income, which sets Medicare IRMAA surcharges on Part B and Part D two years later. A tax-efficient strategy keeps income smooth to avoid crossing IRMAA cliffs. Predictable healthcare spending makes this easier, which is where a Medicare Supplement (Medigap) plan helps by capping out-of-pocket costs.
