Tax Diversification in Retirement: Building Control Over Your Own Taxable Income

Decades of default enrollment have left many households with most of their retirement savings in tax-deferred accounts. That was often the correct decision at the time, particularly for high earners in their peak years. The consequence appears later: withdrawals are generally taxed as ordinary income, and required distributions begin on a schedule set by statute rather than by the household.

When nearly all retirement income is drawn from one treatment, taxable income becomes largely non-discretionary. A large one-time need, such as a roof or a medical event, must be funded from that same pool, potentially pushing the year's income into a higher bracket.

There is no universal target allocation, because the right mix depends on current bracket, expected retirement bracket, state of residence, time horizon, and legacy intent. The useful question is not what percentage is optimal, but whether the household has meaningful balances in more than one category.

A retiree drawing income during an early market decline is selling more shares to produce the same dollar of income. The same average return, arriving in a different order, produces different outcomes. This is sequence-of-returns risk, and it is one of the few risks that becomes more consequential precisely when accumulation ends.

Planning responses generally involve segmenting income by time horizon, so that near-term needs are not funded from assets that must be sold at an unfavorable moment. Structures vary; the principle is consistent.

Moving assets between tax treatments is a taxable event with long-lasting consequences. Whether it is appropriate depends on the difference between your current and expected future brackets, the number of years available before distributions begin, whether outside cash can pay the resulting tax, and how the change interacts with other income-sensitive thresholds.

Any of those factors can reverse the conclusion. This is a modeling exercise with your CPA, not a decision to make from a headline or a rule of thumb.

A practical annual review answers three questions: what does your balance look like across the three tax treatments, what does your projected income look like in your first five years of retirement, and which decisions available to you this year will not be available later.
