Tax-Aware Retirement Withdrawals

In retirement, which account you withdraw from — and when — can matter as much as how much you withdraw. The same dollar of spending can cost very different amounts in taxes depending on its source. Tax-aware withdrawal planning is about keeping more of what you withdraw for yourself.

This is educational information, not tax advice. Tax laws change, and individual circumstances vary. Consult a qualified tax professional regarding your specific situation.

The three account types

Most retirees have assets in three kinds of accounts, each taxed differently:

• Tax-deferred accounts (traditional IRA, 401(k), 403(b)). Withdrawals are taxed as ordinary income. These accounts are generally subject to Required Minimum Distributions (RMDs).
• Taxable brokerage accounts. Only the growth is taxed, generally at long-term capital gains rates, which are usually lower than ordinary income rates.
• Roth accounts. Qualified withdrawals are tax-free, and there are no RMDs for the original owner.

There is no universal "best" order

A common question is which account to draw from first. There is no single right answer. The optimal sequence depends on your tax bracket, your account balances, your age, your RMDs, your Social Security taxation, your Medicare IRMAA tier, and your legacy goals.

Rules of thumb exist, but they are only starting points. What works for one retiree can be costly for another. This is why withdrawal sequencing is best done as part of a coordinated plan, not in isolation.

Social Security taxation

Up to 85% of your Social Security benefit may be taxable, depending on your combined income — which includes tax-deferred withdrawals. Large withdrawals from a traditional IRA can push more of your Social Security into taxable territory. Sometimes spreading withdrawals across years, or drawing from taxable or Roth accounts in certain years, can reduce this.

RMDs and their ripple effects

Traditional tax-deferred accounts generally require withdrawals beginning at a certain age. RMDs are calculated as a percentage of your account balance, so they can be substantial — and they are taxed as ordinary income. An RMD you do not need for spending can still create a tax bill and can push you into a higher bracket or a higher IRMAA tier.

Some retirees manage this by drawing down tax-deferred accounts earlier in retirement — before RMDs begin — to smooth the tax impact over several years rather than concentrating it later.

IRMAA: the hidden tax on retirement withdrawals

Medicare Part B and Part D premiums are income-based through IRMAA, using your income from two years prior. A large withdrawal or Roth conversion can raise your income enough to increase your Medicare premiums for a year. This is one of the more overlooked consequences of withdrawal decisions. (See our guide on Medicare before 65.)

Roth conversions

A Roth conversion moves money from a tax-deferred account to a Roth account, with the converted amount taxed as ordinary income in the year of conversion. The trade-off: pay tax now in exchange for tax-free growth and withdrawals later, no RMDs, and often tax-advantaged inheritance for beneficiaries.

Conversions can be valuable in lower-income years — early retirement before Social Security and RMDs begin, for example. But they are not free: the conversion itself is taxable and can trigger IRMAA. Whether and how much to convert depends on your current and expected tax rates, your time horizon, and your legacy goals.

Capital gains vs. ordinary income

Long-term capital gains rates are generally lower than ordinary income rates. For some retirees, realizing gains in taxable accounts in years when income is low can be efficient. The interaction between capital gains, the standard deduction, and your other income is where careful planning pays off.

Withdrawal sequencing is a multi-year plan

Tax-aware withdrawals are not a one-time decision; they are a multi-year strategy. Looking ahead several years — at RMDs, Social Security, IRMAA, and conversions — lets you smooth income and avoid preventable tax costs. The right sequence is the one that fits your numbers, your tax situation, and your goals.
