Which Account Should You Spend First? Withdrawal Order in 2026

You spent 40 years deciding how much to save and where. Almost nobody plans the reverse: the order in which they spend it down. Yet withdrawal sequencing is one of the few retirement decisions that can add years of portfolio longevity — or hand the IRS tens of thousands of dollars you didn't have to pay — without changing how much you spend or how your investments perform.

The standard advice is a tidy rule: spend taxable first, tax-deferred second, Roth last. It's a fine default. It's also wrong for a large number of retirees, because it ignores the single biggest tax event most retirees will ever face — the one that detonates at age 73.

Here's how the three account types actually behave, why the tidy rule backfires, and the smarter approach built around your 2026 brackets.

The three buckets, and how each is taxed

Every dollar you've saved sits in one of three tax treatments. The whole game of sequencing is deciding which to draw from, when.

Why the conventional order exists

The logic behind "taxable → tax-deferred → Roth" is sound as far as it goes:

• Spend taxable first because that money is already taxed; only the gains are taxable, often at 0% or 15%. Leaving it alone wastes its low-tax status.
• Let tax-deferred keep compounding because every year inside the account is a year of tax-deferred growth.
• Save Roth for last because it grows tax-free, has no RMDs, and is the best asset to leave to heirs. Spending it first throws away its most valuable feature: uninterrupted tax-free compounding.

If you only cared about the next 12 months, this order would be right. The problem is what it does to the next 25 years.

The tidy rule's fatal flaw: the RMD tax bomb

Follow "taxable first" too faithfully and you spend a decade draining your taxable account while your traditional IRA compounds untouched. Then two things happen at once in your early 70s:

1. Required minimum distributions begin at 73. The IRS forces taxable withdrawals from your traditional accounts, whether you need the money or not — and the percentage rises every year.
2. Social Security is usually flowing by then too.

Stack a large forced RMD on top of Social Security and you can trigger a cascade: more of your Social Security becomes taxable (the "tax torpedo"), you jump a bracket, and your income two years earlier may have already pushed you over a Medicare IRMAA cliff. A retiree who felt "low income" at 68 can be forced into a much higher bracket at 75 — purely because the tidy withdrawal order let the tax-deferred bucket grow into a liability.

The irony: by deferring taxes as long as possible, the naive order often maximizes lifetime taxes.

The smarter approach: fill your brackets in the gap years

The highest-value window in most retirements is the stretch between retiring and starting RMDs/Social Security — the "gap years," often ages 62–73. Income is naturally low, which means your lowest brackets are sitting empty. The tax-efficient move is to deliberately fill them.

Here are your 2026 guardrails:

Two moves fill those brackets:

• Partial Roth conversions. Instead of leaving the traditional IRA to balloon, convert a slice each gap year — enough to "fill up" the 12% bracket (or 22%, depending on your plan) at today's low, TCJA-permanent rates. You pay a little tax now to avoid a lot later, and you shrink the future RMD that would have caused the torpedo. See when a Roth conversion ladder pays and when it doesn't.
• 0% capital-gains harvesting. If your taxable income sits below the 0% long-term-gains ceiling ($49,450 single / $98,900 MFJ in 2026), you can realize long-term gains at a 0% federal rate — resetting your cost basis for free. This is a gift specific to low-income years.

The subtlety worth respecting: both moves raise your income, which interacts with the $6,000 senior deduction phase-out (starts at $150,000 MAGI for couples) and the first IRMAA threshold ($218,000 MFJ, two years later). The art is converting up to a line, not past it. That's a multi-variable optimization — exactly what a good calculator is for.

Blended withdrawals often beat strict ordering

Strict sequencing — fully draining one bucket before touching the next — creates exactly the lumpy income that causes bracket spikes. A growing body of research from Vanguard, Schwab, and Morningstar finds that a proportional or blended approach frequently produces a lower lifetime tax bill and longer portfolio life. The idea: rather than "taxable, then tax-deferred, then Roth," draw a mix each year — enough tax-deferred to use up your low brackets, topped off with taxable or Roth to reach your spending target without tipping into a higher bracket. You're smoothing income across all your retirement years instead of front-loading the low-tax years and back-loading a tax bomb. The strict order is a rule of thumb; blended withdrawal is that rule of thumb with the brackets actually in view.

When to break the conventional order

• Legacy planning. Roth is the best asset to leave heirs (tax-free, though most must empty it within 10 years). Taxable accounts get a step-up in basis at death, erasing unrealized gains for your heirs. So if leaving money matters, you may spend tax-deferred faster and preserve both Roth and low-basis taxable assets — the opposite of the tidy rule.
• The widow's penalty. When one spouse dies, the survivor files as single the following year — with roughly half the brackets and standard deduction, and lower IRMAA thresholds. A couple who saw decades of MFJ brackets can watch the survivor get pushed into a much higher rate on the same income. Front-loading Roth conversions while both spouses are alive (and both sets of brackets are available) is one of the most valuable — and overlooked — sequencing moves there is.
• A large one-time expense. Pulling a big sum from a traditional IRA in a single year can spike your bracket and your IRMAA. Where possible, split it across the calendar or source part from Roth/taxable to smooth the hit.

A related lever: asset location

Which account holds which asset compounds the benefit of getting the order right. Because tax-deferred withdrawals are all taxed as ordinary income, that's the natural home for holdings that would throw off ordinary-income tax anyway — bonds and other interest-bearing assets. Because Roth grows tax-free forever, it's the best home for your highest-expected-growth assets (stocks), so your biggest gains are the ones that never get taxed. Taxable accounts sit in between: favor tax-efficient index funds, hold them past a year for the 0/15% long-term rate, and remember they get a step-up in basis at death. Getting asset location and withdrawal order working together, rather than tuning each in isolation, is where the real efficiency lives.

One more lever many retirees miss: after age 70½, qualified charitable distributions (QCDs) let you send money straight from an IRA to charity — satisfying part of your RMD without the distribution ever landing in your taxable income (or your IRMAA MAGI). If you give anyway, giving from the IRA is almost always better than giving cash and taking the full RMD.

Worked example: the gap-year fill

Tom and Linda are both 66, retired, not yet claiming Social Security or taking RMDs. They have $900,000 in a traditional IRA, $200,000 in Roth, and $150,000 in a taxable brokerage account. They need about $70,000/year to live.

The naive path: they live off taxable and cash, leave the IRA untouched. By 73 the IRA has grown past $1.1M, RMDs start near $42,000 and climb, Social Security is flowing, and a big chunk of their benefits becomes taxable. They spend their 70s and 80s in a higher bracket than they ever saw in their 60s.

The tax-efficient path: each gap year they cover living costs from a blend of taxable and IRA, and convert additional IRA dollars to Roth — sized to keep their MAGI near $150,000 so they preserve the full senior deduction and stay comfortably under the IRMAA line. Over seven gap years they move a large slice of the IRA into tax-free Roth at 12–22% rates. By 73 the traditional balance — and the RMD it throws off — is dramatically smaller, their Social Security is taxed more lightly, and they've bought themselves flexibility no single-account strategy provides.

Same portfolio, same spending. A materially different lifetime tax bill.

Model your withdrawal order in Yearfold

The reason sequencing is hard is that every lever moves three others — brackets, the senior deduction, IRMAA, the taxation of Social Security, and future RMDs all interact across decades. In the Yearfold calculator you can test different withdrawal orders and gap-year conversion sizes and watch the lifetime effect on taxes, RMDs, and how long the money lasts. See how we model taxes and withdrawals, and pair this with sequence-of-returns risk and the 4% rule in 2026 — sequencing decides which dollars you spend; those decide how many.

Frequently asked questions

What is the general order to withdraw retirement accounts?

The common default is taxable accounts first, then tax-deferred (traditional 401(k)/IRA), then Roth last — to preserve tax-free growth. But for many retirees a blended approach that fills low brackets with Roth conversions in the gap years beats the strict order.

What is the RMD tax bomb?

Draining taxable accounts while a traditional IRA compounds untouched can leave a very large balance at 73, when required minimum distributions begin. The forced withdrawals, stacked on Social Security, can push you into a higher bracket and trigger IRMAA — often raising lifetime taxes.

Should I do Roth conversions before RMDs start?

Often yes. The low-income "gap years" between retiring and age 73 are ideal for converting traditional dollars to Roth at low rates, shrinking future RMDs. The right amount depends on your brackets, the senior-deduction phase-out, and IRMAA thresholds.

What is the 0% capital gains bracket?

In 2026, long-term capital gains are taxed at 0% while taxable income stays under $49,450 (single) / $98,900 (MFJ). Low-income years let you realize gains — or reset cost basis — at no federal tax.

What is the widow's penalty?

After a spouse dies, the survivor files as single, with roughly half the brackets and deduction and lower IRMAA thresholds. The same income can be taxed much more heavily, which is why converting to Roth while both spouses are alive can pay off.

Does withdrawal order matter if my savings are modest?

Yes — arguably more. With a smaller portfolio, a single avoidable bracket jump or IRMAA surcharge eats a bigger share of your income, and the low-income gap years are still the cheapest time to convert or harvest gains. The dollar amounts are smaller, but the percentage impact on how long your money lasts can be just as large. Sequencing isn't a high-net-worth luxury; it's a lever available to anyone who holds more than one type of account.

Where do RMDs fit into the order?

Once required minimum distributions begin at 73, they're mandatory and come out of tax-deferred accounts whether you planned to touch them or not — which is exactly why shrinking those balances during the gap years matters. After taking the required amount, you still choose where the rest of your spending comes from that year.
