How you withdraw money in retirement matters almost as much as how much you have. Withdrawing from the wrong accounts in the wrong order can cost you thousands in unnecessary taxes every year — and over a 25-30 year retirement, those mistakes compound dramatically.

The Three Account Types and Their Tax Treatment

Account Type Examples Tax Treatment on Withdrawal
Taxable accounts Brokerage, bank accounts Capital gains tax on gains (0/15/20%); dividends taxed as earned
Tax-deferred Traditional IRA, 401(k), 403(b), SEP IRA Ordinary income tax on full withdrawal
Tax-free Roth IRA, Roth 401(k) Tax-free (after age 59½ and 5-year rule)

The Standard Withdrawal Order

Step 1: Take all Required Minimum Distributions (non-negotiable — penalty if skipped)
Step 2: Cover remaining expenses from taxable accounts (favorable capital gains rates)
Step 3: Cover remaining needs from traditional IRA/401(k)
Step 4: Use Roth IRA last (tax-free growth; no RMDs; valuable to preserve)

Account After-Tax Cost of $1 Why in This Order
Taxable (0% LTCG bracket) $1.00 Tax-free for many low-income retirees
Taxable (15% LTCG bracket) $0.85 Preferential rate; basis partially returned
Traditional IRA (22% bracket) $0.78 Ordinary income; higher cost
Roth IRA $1.00 Tax-free; preserve as long as possible

When to Deviate: Bracket Management

The standard order is a starting point. Sophisticated planning often involves deviating for bracket management:

Fill Low Brackets With Traditional IRA Withdrawals

Situation Action
You’re in the 12% bracket with significant traditional IRA funds Draw extra from traditional IRA to fill 12% bracket — cheap taxes now vs. more expensive later
You’ll be in a higher bracket at 73 due to RMDs Withdraw from traditional IRA now at lower rate
Portfolio is 90% traditional IRA with minimal Roth Accelerate traditional IRA spending early to balance account types

Fill Low Brackets With Roth Conversions

Converting traditional IRA to Roth in low-bracket years accomplishes the same goal as drawing from traditional IRA — with the difference that converted funds stay in the tax-free Roth vs. being spent. See Roth Conversion in Retirement for full detail.

Capital Gains Tax Rates: A Key Advantage of Taxable Accounts

Long-term capital gains rates (for assets held >1 year) are much lower than ordinary income rates:

2026 Taxable Income (MFJ) Ordinary Income Rate LTCG Rate
Up to $96,950 10-12% 0%
$96,951-$583,750 22-35% 15%
Over $583,750 37% 20%

Key: Many retirees with modest income qualify for the 0% LTCG rate. A couple with $80,000 total income (including $10,000 in long-term capital gains) pays 0% on those gains.

Tax Gain Harvesting

If you’re in the 0% LTCG bracket, deliberately realize long-term capital gains:

  • Sell appreciated securities
  • Rebuy immediately (no wash sale rule for gains)
  • This “resets” your cost basis higher — reducing future taxable gains

Example: A couple with $75,000 taxable income has $50,000 unrealized long-term gains in a taxable account. They’re below the $96,950 0% LTCG ceiling. They can realize $21,950 of gains tax-free this year, resetting basis. Future sale of those shares will have higher basis, resulting in less taxable gain.

Social Security Taxation: The 85% Inclusion

Social Security benefits are taxable based on your “provisional income” (AGI + tax-exempt interest + 50% of SS benefit):

Filing Status Provisional Income SS Taxable %
Single Under $25,000 0%
Single $25,000-$34,000 Up to 50%
Single Over $34,000 Up to 85%
Married (MFJ) Under $32,000 0%
Married (MFJ) $32,000-$44,000 Up to 50%
Married (MFJ) Over $44,000 Up to 85%

Only 85% of SS is ever taxable — meaning 15% is always tax-free.

Impact on withdrawal order: Every dollar you withdraw from a traditional IRA increases your provisional income, which increases the taxable percentage of Social Security — essentially a “stealth tax” on withdrawals.

The IRMAA Thresholds: Medicare Surcharges

IRMAA surcharges apply when MAGI exceeds thresholds (2026):

MAGI (MFJ) Part B Monthly Premium Part D Surcharge
≤ $212,000 $185/month $0
$212,001-$266,000 $259/month +$12.90/month
$266,001-$334,000 $369/month +$33.30/month
$334,001-$400,000 $479/month +$53.80/month
> $400,000 $590/month +$74.20/month

Staying below $212,000 (MFJ) or $106,000 (single) is a key objective for most retirees.

High-value tactic: Plan large Roth conversions or IRA withdrawals to stay just under IRMAA thresholds.

Year-End Tax Review for Retirees

Before December 31 each year:

Action Purpose
Estimate current year MAGI Know where you are relative to brackets and IRMAA
Check remaining low-bracket room Fill with traditional IRA withdrawals or Roth conversion
Review unrealized gains/losses in taxable account Harvest losses to offset gains; harvest gains at 0% if in range
Confirm RMD has been taken Avoid 25% penalty
Check if QCD makes sense Reduce MAGI with charitable giving from IRA
Consider bunching deductions Itemize in high-income years; standard deduction in lower years

Tax-Efficient Withdrawal by Account Balance Scenario

Portfolio Mix Recommended Approach
Mostly traditional IRA (80%+) Aggressive Roth conversions in tax window; spend taxable first; preserve Roth
Balanced (40% traditional, 30% Roth, 30% taxable) Standard order; moderate Roth conversions to fill 22% bracket
Mostly Roth (60%+) Enviable position; spend taxable first, traditional for large one-time expenses, Roth last
All taxable (no retirement accounts) No RMD concern; focus on capital gains management and deferral
All traditional IRA (no taxable or Roth) Aggressive Roth conversions; QCDs for charitable giving; QLAC to reduce RMDs

Common Tax Withdrawal Mistakes

Mistake Tax Cost
Withdrawing from Roth first Taxing money that could have grown tax-free longer
Ignoring 0% LTCG bracket Missing free tax gain harvesting opportunity
Not doing Roth conversions in the tax window Potentially thousands more in lifetime taxes
Large IRA withdrawal in one year Bracket spike into 24-32%; IRMAA surcharge triggered
Taking SS early just to avoid portfolio withdrawals Smaller SS benefit for life; misses the portfolio withdrawal opportunity at low rates
