Withdrawal Order Explained

You’ve got money in three kinds of accounts. Which one do you spend first? Most people grab the taxable account out of habit and leave real money on the table, because the order you withdraw in is one of the biggest tax levers you control in retirement.

Your three buckets

Retirement savings usually sit in three tax buckets, and each is taxed on a different clock. Taxable accounts, where you owe tax on gains and dividends as they happen. Tax-deferred accounts like traditional IRAs and 401(k)s, where every withdrawal is ordinary income. And tax-free Roth accounts, where qualified withdrawals cost nothing.

The textbook order is taxable first, tax-deferred next, Roth last. That sequence stretches the tax shelter as long as possible and lets the Roth keep compounding untouched. The full logic is laid out in tax-efficient withdrawal order.

Why the lazy order costs you

Spend down the taxable account first and you buy yourself a stretch of artificially low income. That low-income valley is the most valuable real estate in your whole retirement, and most people burn it without noticing.

Why does it matter so much? Because a low-income year is when Roth conversions get cheap and long-term capital gains can be taxed at 0%. Drain the taxable account too fast and you skip straight to ordinary-income withdrawals, surrendering the cheap years you could’ve used to shrink future tax bills.

The second-order trap

Here’s the move the simple rule misses. Leave a big traditional IRA untouched all the way until required minimum distributions hit at 73 or 75, and that account has quietly grown into a tax problem. The forced withdrawals can be large enough to spike your bracket and lift your Medicare premiums two years later through IRMAA, the income-based surcharge.

So the smarter play often isn’t pure taxable-then-deferred. It’s blending. You spend from taxable while deliberately converting or withdrawing just enough from the IRA each year to fill up a low bracket. You’re smoothing income across decades instead of starving early and feasting late.

Don’t optimize taxes into a crash

One caution. Chasing the perfect tax order can quietly wreck your downside protection. If your spending plan forces you to sell stocks in a bad market to hit a tax target, you’ve traded a tax win for sequence-of-returns risk, the danger that early losses while you’re withdrawing do permanent damage. Keep enough safe money that the market never dictates your tax moves.

The order you spend in is a dial, not a default. Turn it on purpose and it can add years to how long your money lasts. Leave it on autopilot and you’re tipping the IRS for nothing.
