Tax-Efficient Withdrawals in 2026
The 2025 One Big Beautiful Bill Act made 2017 tax rates permanent — 2026 brackets stay at 10/12/22/24/32/35/37%. Here's how to tier withdrawals tax-efficiently under current law.
This scenario covers
ContextWhy 2026 Rates Stayed the Same
The Tax Cuts and Jobs Act (2017) temporarily lowered federal tax brackets through 2025, with a scheduled reversion to higher, pre-2018-style rates in 2026. That reversion never happened: the One Big Beautiful Bill Act (OBBBA), signed July 2025, made the TCJA's seven brackets — 10%, 12%, 22%, 24%, 32%, 35%, and 37% — permanent, with routine inflation adjustments each year. For most retirees, 2026 marginal rates are the same brackets they've planned around since 2018, just with higher inflation-adjusted thresholds.
| 2026 Taxable Income (single) | Rate |
|---|---|
| $0–$12,400 | 10% |
| $12,400–$50,400 | 12% |
| $50,400–$105,700 | 22% |
| $105,700–$201,775 | 24% |
ImpactHow Account-Type Composition Affects Your Tax Bill
A retiree drawing $80,000/year in total spending pays dramatically different federal tax depending on which accounts fund it — even though the 2026 brackets themselves didn't change. Traditional IRA withdrawals and Social Security are largely taxable; Roth withdrawals are not, and keeping other income low can also keep Social Security itself untaxed.
| Income composition | Federal tax (2026) |
|---|---|
| $80K total ($30K Social Security + $50K Traditional IRA) | $7,780 |
| $80K total ($30K Social Security + $50K Roth) | $0 |
StrategyThe Ongoing Case for Roth Conversions
Because OBBBA made the 12% and 22% brackets permanent, there's no year-end deadline pressuring retirees to convert before rates rise. But the underlying strategy is still valuable every year: converting Traditional IRA funds while your current bracket is lower than the bracket your future RMDs will land you in.
- For retirees currently in the 12% bracket: Converting up to the top of that bracket ($50,400 taxable income, single, 2026) locks in a 12% rate on funds that would otherwise be taxed at 22%+ when RMDs force them out later.
- For retirees approaching RMD age (73): Pre-converting reduces the Traditional IRA balance and future RMDs — permanent rate certainty makes this easier to plan around than when a rate change loomed.
- Interaction with SS taxation: Higher income increases the portion of SS benefits subject to tax (from 0→50→85%). Conversions should account for this threshold effect regardless of bracket levels.
ExecutionTax-Tiered Withdrawal Strategy
A tax-tiered approach sequences withdrawals to minimize annual taxes across all years — not just the current year. The goal is to "smooth" taxable income across brackets rather than taking large taxable withdrawals that push into higher rates.
| Tier | Source | Tax rate | Use when |
|---|---|---|---|
| 🥇 Tier 1 (free) | Roth IRA, Roth 401k | 0% | Always beneficial; first priority for large expenses |
| 🥈 Tier 2 (low) | Taxable brokerage (LTCG) | 0–15% | After Roth; especially when in 12% bracket |
| 🥉 Tier 3 (ordinary) | Traditional IRA / 401k | 10–37% | Fill remaining bracket; minimize year-by-year |
| 📅 SS income | Social Security | 0–85% includable | Use other tiers first to minimize SS taxation |
Verdict: How Much Can Strategic Tiering Save?
Over a 25–30-year retirement, a tax-tiered withdrawal strategy consistently saves $50,000–$150,000 in lifetime taxes vs. a naive "withdraw from IRA as needed" approach. With 2026 rates now permanently set at the same 10–37% structure retirees have planned around since 2018, there's no rush — but converting at today's known rates still beats deferring into higher RMD-forced brackets later. The strategy starts with understanding your account mix and a few hours of planning.
