Retirees Who Spend From the Wrong Account First Run Out About Three Years Sooner. Here’s the Order That Adds Six Figures.

The sequence in which you pull from your retirement accounts matters far more than most retirees realize, and a mistake made in the early years can quietly shrink a portfolio in ways that only become visible decades too late.

This is also only one modeled scenario, and the outcome is highly sensitive to the assumptions behind it. Take a 65-year-old couple with $1.5 million split roughly a third each across a taxable brokerage, a traditional IRA, and a Roth. They spend about $78,535 a year, which is the average consumer expenditure for households in that age range, and they earn a 6% return with 2.5% inflation. Filing jointly in the 12% bracket, a naive withdrawal sequence can shorten portfolio longevity by about three years, while an optimized strategy preserves six figures of additional wealth over a 30-year retirement.

Change any of those inputs, including the asset mix, the spending level, or the tax bracket, and both numbers shift significantly. A retiree with nearly everything concentrated in a single account type will see almost no impact at all.

That caveat matters because the common advice is a strict order: taxable first, then tax-deferred (traditional IRAs and 401(k)s, taxed as ordinary income on withdrawal), and Roth last. The logic makes surface-level sense. Tax-advantaged accounts get more years to compound, and taxable withdrawals often qualify for long-term capital gains rates, which are lower than ordinary income rates.

Why the Simple Order Backfires

Draining the brokerage first while the traditional IRA keeps growing sets up a larger problem later. Required minimum distributions, the IRS-mandated annual withdrawals from tax-deferred accounts, now begin at age 73 for those born between 1951 and 1959, and at age 75 for those born in 1960 or later. A larger IRA at 73 means a larger forced withdrawal, which can push a retiree from the 12% bracket into the 22% bracket. That 22% rate starts at $100,800 of taxable income for joint filers in 2026.

The same income spike can trigger a Medicare surcharge. The income-related monthly adjustment amount (IRMAA) uses a two-year lookback on modified adjusted gross income. In 2026, a joint filer crossing $218,000 pays an extra $81.20 per month on Part B, rising to $487 above $750,000, with Part D surcharges from $14.50 to $91 stacked on top. A single large RMD can trip those cliffs for an entire calendar year.

Bracket Filling: The Better Answer

The more sophisticated approach uses the low-income window between retirement and age 73 to deliberately fill the lower brackets each year. That can mean pulling from the traditional IRA up to the top of the 12% band, or executing a Roth conversion to the same ceiling, while covering remaining spending from the brokerage. With the 2026 standard deduction of $32,200 for joint filers, a couple can realize meaningful income before any tax hits. Couples where both spouses are 65 or older also benefit from an additional $1,650 per person in standard deduction, plus a new $6,000 per-person deduction available under current law for those under the income phase-out threshold, further widening the room to convert or withdraw at low rates. (We sized up that pre-RMD conversion window in detail in a free Roth guide.)

Retirees in the 12% ordinary bracket also sit in the 0% long-term capital gains bracket, one of the most valuable and least used provisions in the code. Harvesting gains in the taxable account at 0% resets the cost basis without triggering any federal tax liability.

Special Cases That Change the Order

Roth accounts carry no RMDs for the original owner, allowing them to compound and pass to heirs income-tax-free. Qualified charitable distributions, available at age 70½ and capped at $111,000 per person in 2026, let a retiree satisfy an RMD by sending money directly to charity. That amount stays entirely out of adjusted gross income and away from IRMAA calculations.

A large embedded gain in the brokerage account is often worth preserving rather than selling, because heirs receive a step-up in basis at death that wipes out the built-in capital gains tax. Meanwhile, a surviving spouse who transitions to single filing faces compressed brackets, where the 22% rate kicks in at just $50,400 in 2026. Front-loading Roth conversions while both spouses are alive is one of the clearest ways to protect the survivor from that future single-filer tax squeeze.

An Ordered Framework

1. Cover baseline spending with Social Security and any pension. The SSA officially set the 2027 COLA at 3.6%, the largest increase since 2023, effective January 2027.
2. Fill the 12% bracket with traditional IRA withdrawals or Roth conversions in the pre-RMD window.
3. Take the rest from the taxable account, harvesting gains at 0% when eligible.
4. Use QCDs after 70½ to blunt RMDs.
5. Preserve Roth balances for late-life spending and heirs.

The right sequence is personal. It depends on account mix, spending, state tax, and health. Paying a fee-only planner to model it once and revisit it after any large market move or tax-law change is one of the highest-return decisions a retiree can make.
