Retirement Income Distribution Strategy: Account Sequencing
Withdrawal order is choosing which of your taxable, pre-tax, and Roth accounts fund each year of retirement to manage lifetime taxes.
Retirement Income Distribution Strategy: Account Sequencing
1 / 7
The short answer
- Account sequencing means deciding each year how much to draw from taxable, tax-deferred, and Roth accounts.
- The goal is usually to manage lifetime taxes and income-based costs, not just this year's tax bill.
- A fixed rule like spending taxable first, then pre-tax, then Roth can push large RMDs into high brackets later.
- A year-by-year approach looks at bracket space, Medicare and ACA thresholds, and future RMDs together.

The short answer

How is each account type taxed?
- Taxable brokerage: only gains are taxed, and long-term gains can qualify for 0%, 15%, or 20% federal rates.
- Tax-deferred (traditional 401(k) and IRA): every dollar withdrawn is ordinary income.
- Roth: qualified withdrawals are tax-free and do not raise adjusted gross income.
- In 2026, the 0% long-term gains rate applies up to $49,450 of taxable income for singles and $98,900 for joint filers.
What does a dynamic withdrawal strategy look like?
- Each year, estimate taxable income and how much room remains before the next bracket or threshold.
- Fill lower brackets with pre-tax withdrawals or Roth conversions, often in the years between retiring and RMDs.
- Use taxable accounts for spending beyond that, where only the gain portion is taxed.
- Keep Roth assets for high-income years, late-life costs, or heirs, since Roth money has no lifetime RMDs.
How do RMDs change the picture?
- RMDs begin at 73 for people born 1951–1959 and at 75 for those born in 1960 or later.
- Large pre-tax balances can force withdrawals that raise brackets, Social Security taxation, and Medicare premiums.
- Withdrawals or Roth conversions before RMDs start can shrink future required amounts, at the cost of paying tax sooner.
- Qualified charitable distributions from IRAs after 70½ can count toward RMDs without adding to AGI.
Which income thresholds matter most in 2026?
- Medicare IRMAA surcharges for 2026 start above $109,000 single or $218,000 joint of 2024 MAGI, a two-year lookback.
- 2026 surcharges add roughly $1,100 to $6,900 per person per year for Parts B and D combined.
- Before 65, enhanced ACA subsidies expired after 2025, so income above 400% of the poverty line loses premium credits entirely.
- Up to 85% of Social Security can become taxable, and the new 65-and-older deduction phases out above $75,000 single or $150,000 joint.
Trade-offs and uncertainties
- Paying tax earlier through conversions is a bet that future rates will be similar or higher; that outcome is uncertain.
- Spending taxable assets early can reduce the step-up in basis heirs might otherwise receive at death.
- Tax law changes, such as the July 2025 law, can move brackets and thresholds after a plan is set.
- A plan revisited annually with actual income and balances tends to stay closer to its intent.
Key takeaways
- Withdrawal order is a yearly decision, not a fixed sequence set at retirement.
- The years between retirement and RMDs are often the most flexible for managing brackets.
- IRMAA, the ACA subsidy cliff, and Social Security taxation can matter as much as brackets.
- Rubric Advisors does not prepare tax returns; confirm conversion and withdrawal amounts with a CPA.
