Tax-Efficient Withdrawal Order

Does the order you tap your accounts in retirement really change anything, if you’re spending the same amount either way? It changes your lifetime tax bill, sometimes by six figures. The dollars you spend are the same. The taxes you pay to free them are wildly different depending on which account you drain first, and the conventional advice usually leaves money on the floor.

The old rule, and where it breaks

The textbook order is simple: spend your taxable accounts first, then tax-deferred (traditional IRA and 401(k)), then Roth last. The logic is to let the tax-sheltered accounts compound as long as possible.

It isn’t wrong, exactly. It’s incomplete. Follow it blindly and you spend your 60s in a low tax bracket while your traditional IRA quietly balloons. Then RMDs hit at 73 or 75, the forced withdrawals land on top of Social Security, and you’re suddenly in a higher bracket in your late 70s than you ever were while working. The rigid order wins the early years and loses the war.

Think in brackets, not buckets

The better frame is to stop thinking about which account and start thinking about which tax bracket you’re filling. Every year you have low-bracket room going unused is a year you wasted cheap tax space you’ll never get back.

The move that flows from this: in low-income years, deliberately pull income into the cheaper brackets even if you don’t need the cash. That usually means partial Roth conversions in your 60s, before RMDs and often before Social Security begins. For 2026, a married couple filing jointly stays in the 12% bracket on taxable income up to $24,800 and in the 22% bracket up to $100,800. Filling that room on purpose, year after year, shrinks the traditional balance that would otherwise be force-fed to you later at a higher rate.

Done well, this is the opposite of the old rule. You touch the tax-deferred account early, on your terms, instead of letting it grow into a problem the IRS controls.

Watch the cliffs the brackets hide

Income in retirement triggers more than income tax, and the withdrawal order has to respect the tripwires:

• Social Security taxation. Once your provisional income clears $32,000 for a married couple ($25,000 single), more of your benefit becomes taxable, up to 85% of it. These thresholds are fixed in law and don’t rise with inflation, so they catch more people every year.
• Capital gains rates. For 2026, a married couple with taxable income up to $98,900 pays 0% on long-term gains. Sequencing income to stay under that line can let you harvest gains tax-free.
• IRMAA. Push your MAGI over $218,000 (married) or $109,000 (single) for 2026 and you trigger IRMAA, the income-based Medicare surcharge, on a two-year lookback. The withdrawal that saved you 2% in tax can cost you a Medicare tier two years later.

If your accounts are large

For a $3M+ household, the danger is concentration. A large traditional IRA throws off a large forced RMD, and that income only climbs as the balance compounds. The whole point of a multi-year withdrawal plan at this level is to bleed the tax-deferred account down through your 60s, using conversions and strategic withdrawals, so the eventual RMD lands at a manageable size instead of a punishing one.

This is also where asset location and a bucket strategy start working together. The order you withdraw and the place you hold each asset are the same decision viewed from two angles.

The withdrawal order isn’t a fixed sequence you set once. It’s a yearly decision: how much income to recognize, in which bracket, before the next cliff. Spend with one eye on the tax return, and you keep money that the autopilot rule would have handed to the IRS.
