Which account do you tap first in retirement? The order matters more than most Utah retirees realize. A 2023 Vanguard study found that optimal tax-efficient withdrawal sequencing added an average of $187,000 in after-tax lifetime income for a median retiree versus simply draining accounts in the wrong order.
In 2026, with federal 0% capital gains brackets up to $98,900 (married), Utah's flat 4.45% state tax, and Medicare IRMAA cliffs at $218,000 of income for couples, the arithmetic of sequencing has gotten sharper. Here's the strategy that works in Utah.

The Standard Withdrawal Order (and When to Break It)
The textbook sequence is:
- Taxable brokerage accounts first
- Traditional IRA and 401(k) second
- Roth IRA last
The logic: drain taxable accounts, defer taxes on traditional accounts, and keep tax-free Roth money growing untouched as long as possible. This standard works if you're in your normal tax bracket. But in early retirement (62–72), before required minimum distributions force larger withdrawals, you're often in an artificially low bracket—and that's where the optimization wins.
The 2026 Tax Brackets That Change Everything
For married couples in 2026:
- 0% long-term capital gains rate up to $98,900 of taxable income
- 12% federal tax bracket for taxable income up to $100,800
- 22% federal tax bracket from $100,801 to $201,600
- Utah's flat 4.45% state tax on top of everything
Here's the power: if you and your spouse have $60,000 of combined income in year one of retirement, you have $38,900 of room to fill before hitting the 22% federal bracket. That's space to recognize capital gains, execute Roth conversions, or take larger traditional IRA withdrawals—all at rates far lower than you paid while working.
Why Utah's Flat 4.45% Tax Matters
Unlike many states that exempt retirement income, Utah taxes it all equally. Your IRA distributions, 401(k) withdrawals, Social Security (with a partial credit), and investment income all stack into Utah's flat 4.45% bracket. What matters is total income and federal tax efficiency.
The Roth Conversion Strategy: Fill Low Brackets Early
If you retire at 62 and don't claim Social Security until 70, your first 8 years might include just $20,000–$40,000 of annual household income. That's the window to convert traditional IRA money to a Roth:
- Take $30,000 from a taxable account to live on
- Convert $40,000 from a traditional IRA to a Roth
- Pay federal and Utah tax on the conversion at low rates (~$13,000 combined)
- That $40,000 grows tax-free in the Roth for 30+ years
The catch: the conversion counts as income two years later for Medicare IRMAA.
The Medicare IRMAA Cliff You Can't Ignore
Medicare Part B and Part D surcharges begin at $109,000 MAGI (single) or $218,000 (married) in 2026. Exceed the threshold by $1 and you pay the higher tier for the entire year. A large withdrawal or Roth conversion can cost thousands in Medicare premiums two years later.
The Net Investment Income Tax (3.8%) for Higher Incomes
If your MAGI exceeds $200,000 (single) or $250,000 (married filing jointly), an additional 3.8% tax applies to net investment income. Traditional IRA withdrawals themselves aren't subject to this tax, but they do raise your MAGI, potentially pushing your investment income into NIIT territory.
A Worked Example: Utah Couple, Ages 62 & 65
Scenario: Married couple, both retired. They have $800,000 in traditional IRAs, $200,000 in a Roth, and $150,000 in a taxable brokerage. Social Security starts at 70. They need $60,000 annually to live on.
Years 1–8 (before Social Security):
- Withdraw $40,000 from taxable brokerage (mainly gain; 0% capital gains rate)
- Withdraw $5,000 from traditional IRA
- Convert $15,000 from traditional IRA to Roth (fills 12% bracket gap)
- Total income: ~$60,000; federal tax: ~$6,000; Utah tax: ~$2,700; after-tax: $51,300
The FAQ
Should I always tap taxable accounts first?
Not if you're in a low tax bracket. If you're below the 22% federal bracket and not triggered by IRMAA, a Roth conversion or larger traditional withdrawal might be better.
What if I have company stock in a 401(k)?
The Net Unrealized Appreciation (NUA) strategy may apply: withdraw the stock and pay tax only on cost basis. Consult a CPA—this is easy to botch.
Does the withdrawal sequence matter if I'm past 73?
Yes. Once RMDs are forced, the sequence is constrained, but you still control whether to take extra traditional withdrawals, Roth conversions, or taxable account withdrawals.
Should I coordinate my Social Security claiming with withdrawals?
Absolutely. Delaying Social Security to 70 (from 62) raises your check ~76% but forces higher withdrawals in years 62–69. Use the low-income years to convert IRAs and fill the 0%/12% brackets, then let Social Security take over.
The Bottom Line
Tax-efficient withdrawal sequencing isn't one rigid order—it's a coordinated strategy that evolves as you age. In 2026 Utah, the biggest wins come in the 10 years before you claim Social Security, when you can fill low federal tax brackets with Roth conversions and taxable-account gains while staying below the Medicare IRMAA cliffs.
