Tax-Efficient Retirement Withdrawals

Accumulating retirement savings is only half the equation. How you withdraw those savings can be just as important as how much you saved. Most retirees hold assets in multiple account types, each with different tax treatment: taxable brokerage accounts, traditional IRAs and 401(k)s (tax-deferred), and Roth IRAs (tax-free). The sequence in which you tap these accounts directly affects your tax bill, your Medicare premiums, and how long your portfolio lasts.

The Conventional Approach

The traditional withdrawal sequence begins with taxable accounts, then moves to tax-deferred accounts, and uses Roth accounts last. The logic is that taxable accounts generate annual income regardless of withdrawals (from dividends and capital gains), tax-deferred accounts grow more efficiently when left untouched, and Roth accounts benefit most from extended tax-free compounding. For many retirees, this sequence is a reasonable starting point.

Why the Conventional Approach Falls Short

The conventional approach does not account for tax bracket management. By drawing only from taxable accounts in early retirement, you may leave your tax-deferred accounts to grow unchecked, resulting in larger required minimum distributions (RMDs) at age 73 that push you into higher brackets. A more nuanced approach involves strategically drawing from tax-deferred accounts in years when your income is low, filling up lower tax brackets and reducing future RMDs.

Roth Conversions as Part of the Strategy

The years between retirement and the start of Social Security or RMDs often represent a low-income window that is ideal for Roth conversions. By converting a portion of your traditional IRA each year, you pay tax at today's lower rate and shift assets into an account that will never be taxed again. This reduces future RMDs and creates more flexibility in managing your tax bracket in later years.

Putting It All Together

An optimized withdrawal strategy considers your current and projected tax brackets, Social Security timing, healthcare costs, estate planning goals, and anticipated changes in the tax code. At Whitwell & Co., we build multi-year withdrawal projections for each client to ensure that every dollar withdrawn is done so in the most tax-efficient manner possible.
