What Is the Best Withdrawal Order for Taxable, Traditional IRA, 401(k), and Roth Accounts?

The withdrawal order that often gets tested first is taxable brokerage cash, then traditional IRA and pretax 401(k) money, with Roth accounts later. That sequence is a starting sketch, not a rule. The better order is the one that pays your bills, keeps this year's taxable income in a range you accept, and does not leave you with a huge required withdrawal later. For some households, spending some Roth money earlier, or converting IRA money instead of only spending it, is the stronger plan.

Taxable, traditional, and Roth accounts are taxed differently when you spend them. A 401(k) that was funded with pretax dollars behaves, once rolled to an IRA or withdrawn, much like a traditional IRA. A Roth 401(k) is closer to a Roth IRA, with its own rollout details. Treat "401(k) versus IRA" as a question about pretax versus Roth, plus any plan-specific rules, not as four unrelated products.

How each bucket is usually taxed when you spend it

Account	What a withdrawal often does
Taxable brokerage	You may owe tax on interest, dividends, and capital gains. Spending cash or selling shares with little gain can raise living money without a large ordinary-income hit. Selling shares with a large gain is different.
Traditional IRA and pretax 401(k)	Withdrawals are generally ordinary income. After RMD age, a minimum amount must come out whether you need it or not.
Roth IRA and Roth 401(k)	Qualified withdrawals are generally tax-free. Spending them early saves tax today and gives up tax-free dollars you might have wanted at 85.

Those sentences hide exceptions: early withdrawal penalties, Roth five-year rules, basis in a nondeductible IRA, and employer stock in a 401(k). IRS Publication 590-B is the reference for IRA withdrawals. Read it when the account is not a simple pretax balance.

Why "taxable, then traditional, then Roth" is only a sketch

Spending taxable assets first lets pretax and Roth accounts keep growing. It can also leave a large traditional IRA in place, so required minimum distributions later are larger and more of your Social Security becomes taxable. Spending only from the Roth account first does the reverse: this year's tax bill looks wonderful, and the pretax account is still waiting, often with a bigger RMD problem.

A blended year is common. You might spend dividends from the taxable account, withdraw enough from the IRA to fill a bracket, and leave the Roth account alone. Or you might withdraw from the IRA for spending and also convert an additional slice, which is the topic of how much to convert to Roth. Conversion is not a withdrawal for spending. It moves money and creates tax without giving you cash unless you withhold or set money aside.

How long the portfolio lasts, discussed in how long retirement money lasts, depends on this choice. Two households with the same balances can run out at different times if one pays much more tax on every dollar of spending.

Tradeoffs by decade

Before required withdrawals, you have the most choice. You can favor the taxable account, take IRA money on purpose, or convert. After RMDs start, the traditional account sends a minimum amount first. You still choose what to do above that minimum: spend it, convert additional amounts only after the RMD is satisfied, or use Roth and taxable money for the rest of the budget. A surviving spouse who will file alone may face higher brackets on the same income, which is a reason some couples spend or convert pretax money while both are alive.

Reducing taxes in retirement is the result you are aiming at. Withdrawal order is the method.

Common mistakes

Rolling every 401(k) to an IRA without checking whether the 401(k) had a feature you needed, such as penalty-free access at 55 after leaving that employer, is a mistake people cannot easily undo. Another is selling highly appreciated taxable shares in the same year as a large IRA withdrawal and being surprised that both show up on the return. A third is treating a Roth account as untouchable even when spending a little of it would keep Medicare premiums or a tax bracket in a better place. And some people forget that a 401(k) loan or a hardship withdrawal is not a retirement income plan.

What this means for your retirement plan

Write down the four buckets you actually have, not a textbook set. Note which dollars are pretax, which are Roth, and which are already taxed. Then pick this year's spending from the mix that keeps income, Medicare, and the later RMD in view. Revisit the order when Social Security starts or a spouse's income changes. Analyze a withdrawal plan using your own account mix, taxes, and income needs.

Frequently asked questions

Should I always withdraw from taxable accounts first?

Not always. It is a reasonable default when it keeps ordinary income lower and the taxable account holds cash or high-basis shares. It is weaker if it leaves a traditional IRA so large that later required withdrawals become the tax problem.

Is a 401(k) withdrawn before an IRA?

Pretax 401(k) and traditional IRA withdrawals are both generally ordinary income. The order between them depends on fees, investment choices, plan rules, and whether one account has a required withdrawal. Tax character matters more than the logo on the statement.

When should Roth money be spent?

Often later, so tax-free dollars are available when RMDs, medical costs, or a surviving spouse's tax return are harder. Spending some Roth money earlier can still help if it prevents a costly tax or Medicare threshold.

Does withdrawal order change how long my money lasts?

It can. Taxes paid are dollars that do not stay invested. A more tax-efficient mix can leave a larger balance, but only if the spending level itself is sustainable.
