The Withdrawal Order That Can Save You Six Figures in Retirement Taxes

You spend forty years carefully saving and investing for retirement.

Then, on the way out, one overlooked decision quietly decides how much of it you keep.

It is the order you withdraw from your accounts, and getting it wrong can cost six figures in taxes you never owed.

Almost everyone obsesses over how to save: Roth or traditional, this fund or that one. Almost nobody plans how to un-save. Yet the sequence you tap your accounts in retirement can swing your lifetime tax bill by more than the price of a house. The IRS does not send a warning. It just quietly collects the difference.

Here is how the sequence works, and how to keep far more of what you built.

First, know your three buckets

Every dollar you have saved lives in one of three kinds of accounts, and each is taxed completely differently when you withdraw.

Taxable accounts, like a regular brokerage account, are the most flexible. You already paid tax on the money going in, so you only owe tax on the gains, usually at the lower long-term capital-gains rates, and you control exactly when to realize them.

Tax-deferred accounts, your traditional 401(k) and IRA, are the opposite. You got a deduction going in, and now every dollar you pull out counts as ordinary income, taxed at your regular rate.

Tax-free accounts, your Roth, are the prize. Qualified withdrawals are completely tax-free, and there are no required withdrawals ever.

The order you draw from these three is the entire game.

The default order, and why it usually works

The classic rule of thumb is simple: spend your taxable account first, your tax-deferred accounts second, and your Roth last.

The logic is sound. You drain the account with the lowest tax cost early, since capital gains are taxed gently. Meanwhile your tax-deferred and Roth accounts keep compounding, and you preserve the tax-free Roth for as long as possible, because every extra year it grows is a year of gains the IRS will never touch.

And to be clear, arranging your affairs to pay less is entirely legitimate. As Judge Learned Hand wrote in a famous 1934 ruling:

Anyone may arrange his affairs so that his taxes shall be as low as possible; he is not bound to choose that pattern which best pays the treasury.

This is planning, not evasion. The default order is a fine starting point. The trouble is what it quietly sets up if you follow it too literally.

The tax bomb waiting at 73

Here is the flaw in draining taxable first and leaving your traditional 401(k) untouched.

While you spend down the other accounts, that big pre-tax balance keeps growing. Then, at age 73, the government forces you to start pulling it out through required minimum distributions, whether you need the money or not. By then the account can be so large that those mandatory withdrawals shove you into a higher bracket than you were ever in, spike the taxation of your Social Security, and trigger surcharges on your Medicare premiums.

That pre-tax balance was never entirely yours. As retirement expert Ed Slott likes to say:

Your IRA is a joint account with the IRS.

You just do not know what the government’s share will be until you withdraw, and RMD rules mean the government eventually decides the timing for you. Follow the default order too strictly and you march straight into that trap, having done everything you were told.

The golden window between 60 and 73

This is where the real money is made, and it is the part most retirees miss.

There is often a stretch of years, after you stop working but before Social Security and RMDs kick in, when your taxable income falls unusually low. That window, sometimes a decade long, is a gift. Your low income means you have room to pull money out of that pre-tax account cheaply, filling up the low brackets on purpose, instead of waiting for RMDs to force it out expensively later.

The same window lets you take advantage of the 0% long-term capital-gains rate. In 2026 a married couple with taxable income under roughly $96,000 pays zero on long-term gains. Zero. You can realize gains from your taxable account, or convert part of your traditional IRA to Roth, at rock-bottom rates during these years.

So instead of one bucket at a time, you blend. Each year you deliberately draw a mix, some from tax-deferred to fill the low brackets, some tax-free from Roth, some gains from taxable at the 0% rate, keeping your total taxable income under control every single year. That blend, repeated across a decade, is what quietly saves six figures.

Picture two retirees with identical savings. The first follows the old rule, lives off the taxable account, and lets the traditional IRA balloon untouched until 73 forces huge, highly taxed withdrawals. The second spends those same early years deliberately drawing down and converting that pre-tax balance at 10 or 12%. By the time RMDs arrive, the second retiree has a much smaller pre-tax balance, smaller forced withdrawals, a lower bracket, less Social Security taxed, and no Medicare surcharge. Same money saved. A wildly different lifetime tax bill, decided entirely by sequence.

One order does not fit everyone

One reason the Roth usually comes last deserves its own mention. Because it has no required withdrawals and never gets taxed, it is the most valuable dollar to keep growing and the best one to leave behind. Spend it too early and you waste its biggest advantage. Save it, and it becomes both your cushion for expensive late-life years, like long-term care, and the cleanest inheritance you can pass on, since your heirs receive it tax-free.

That said, there is no single sequence that is right for everybody, and anyone who says otherwise is selling something.

Your ideal order depends on how big your pre-tax balance already is, your other income, your bracket now versus later, and how much you care about leaving money to heirs. Someone with almost everything in a traditional 401(k) has a very different job than someone who saved mostly in Roth. A big pension changes the math again.

The point is not to memorize one rule. It is to stop withdrawing on autopilot and start deciding, every year, which dollars to pull so your income lands where you want it. That yearly decision is the difference between a plan and a surprise.

The Best Proven Paths to Achieve Financial Independence Within 10 Years

You do not need to solve your whole retirement today. You just need to know your map.

So take ten minutes and sort your savings into the three buckets: taxable, tax-deferred, and tax-free. Add up each one. If nearly everything you own sits in a traditional 401(k) or IRA, that is your early warning: you have a large silent partner in the IRS, and a tax bomb quietly building for age 73. The fix, started years early, is to build up the other two buckets and use those low-income years well.

The saving was the hard part, and you did it. Do not hand a fortune back at the end simply because nobody told you the order matters.
