Retirement Tax Myth: Why Deferring Taxes Until Retirement Helps Only 4%

David Brooks says the 'wait until retirement' tax myth only benefits about 4% of people. Learn why deferring taxes can backfire and how to plan smarter.

Many retirees have been told to 'defer, defer, defer' when it comes to taxes on retirement accounts. On the Retire SMART podcast, retirement advisor David Brooks criticized this long-standing rule of thumb: 'So many advisors have helped clients defer, defer, defer, because we all been told this myth, right? Defer your taxes because you'll be in a lower tax bracket when you retire.' Brooks argues that this advice only truly helps a small fraction of people — roughly 4% — and might hurt most others.

Why does the 'wait until you retire' tax myth fail for so many? First, required minimum distributions (RMDs) from traditional IRAs and 401(k)s can push retirees into higher tax brackets later in life. Second, a larger taxable income can increase the taxation of Social Security benefits and trigger higher Medicare premiums (IRMAA). Third, tax laws and rates change over time; expecting a permanent drop in your federal or state tax rate is risky.

Traditional tax-deferred accounts still have a place in retirement tax planning, but treating them as the only tool is short-sighted. Instead of an all-or-nothing approach, many advisors now recommend tax diversification: a mix of tax-deferred (traditional IRA/401(k)), tax-free (Roth IRA/401(k)), and taxable accounts gives retirees flexibility to manage tax brackets and withdraw strategically.

Roth conversions are one practical alternative. Converting portions of a traditional IRA to a Roth while your income is relatively low can lock in today's tax rates and produce tax-free withdrawals later. Partial Roth conversions, timed across several years, help avoid large tax spikes and reduce future RMDs. Other tactics include tax-efficient withdrawals from taxable accounts, using municipal bonds for tax-free income, and planning withdrawals around low-income years.

Bottom line: retirement tax planning should be individualized, not based on a blanket 'defer until retirement' rule. David Brooks' warning highlights that deferring taxes benefits a small minority. Work with a trusted retirement advisor, run projections of tax brackets and RMDs, and build tax diversification into your retirement plan so you can minimize taxes and protect income throughout retirement.
