How to Minimize Taxes in Retirement: 7 Strategies for 2026

For many retirees, taxes — not investment returns — are the biggest variable in how long their money lasts. A household with $1.5M in traditional IRA assets paying 22–24% on every dollar of withdrawal faces a very different outcome than the same household paying 12% by planning ahead. The good news: in retirement you have more control over taxable income than at any point in your working life. Seven strategies determine how much of that opportunity you capture.

Why retirement taxes are uniquely controllable

During your working years, your employer determined when and how much income you received. In retirement, you choose which accounts to draw from, when to take Social Security, how much to convert to Roth, and when to realize capital gains. Each choice affects your taxable income for that year — and those choices compound over 20 to 30 years.

The federal tax system creates several windows that don't exist for workers: a 0% long-term capital gains rate, a low-bracket window before RMDs begin, and the ability to exclude charitable distributions from income entirely. Retirees who understand these windows and plan around them can legally keep far more of their savings than those who don't.

Strategy 1 — Master your withdrawal order

The standard advice — spend taxable accounts first, then traditional IRA, then Roth last — is a reasonable default, but most retirees benefit from a more nuanced approach. The core principle: match each dollar of spending to the lowest-taxed source available in that year.

• Taxable brokerage accounts: Long-term gains taxed at 0–15–20% depending on your total income. In the 0% window ($98,900 MFJ taxable income in 2026¹), selling appreciated shares costs nothing in federal tax. These accounts also receive a stepped-up cost basis at death, making them ideal to hold for heirs.
• Traditional IRA / 401(k): Every dollar is ordinary income. The goal is to withdraw enough to fill your lowest brackets — without spilling into higher ones unnecessarily.
• Roth IRA: Qualified withdrawals are 100% tax-free and don't appear in MAGI — meaning they don't trigger IRMAA surcharges, don't affect Social Security taxation, and don't count toward RMD amounts. Reserve Roth dollars for years when other income is elevated.

See the full mechanics in the tax-efficient withdrawal order guide, including IRMAA interaction and the bracket-fill technique.

Strategy 2 — Fill tax brackets before RMDs force you to

In 2026, the 12% federal bracket tops out at $100,800 of taxable income for married couples ($50,400 for single filers).¹ With the $32,200 standard deduction for married couples, that means up to ~$133,000 of gross income stays at 12% or below — with the first ~$57,000 (standard deduction + 10% bracket) taxed at 10% or nothing.

If your current income — Social Security, pensions, dividends — leaves room below that ceiling, you have an opportunity: withdraw extra dollars from your traditional IRA now, at 12%, rather than waiting for RMDs to force those withdrawals at a higher rate.

Whether those extra withdrawals are spent, reinvested in taxable accounts, or converted to Roth is a secondary decision — but the rate difference compounds either way. Use the RMD calculator to see what forced distributions will look like at 73 or 75, and the Roth conversion calculator to model partial conversions in the same window.

Strategy 3 — Roth conversions in the 60–73 window

Between retirement and RMD age, most retirees pass through the lowest-bracket years of their financial lives: earned income has stopped, Social Security may not have started (or is partially deferred), and RMDs haven't begun yet. This window — roughly ages 60 to 73 — is typically the only time you can move large sums from traditional to Roth at your lowest rate.

The mechanics: you withdraw from a traditional IRA and either spend the dollars or reinvest in Roth (paying tax now). The converted amount reduces future RMDs and shifts future growth to tax-free.

The 2026 conversion math for married couples:¹

• 12% bracket fills to $100,800 taxable income ($133,000 gross after $32,200 standard deduction)
• 22% bracket: $100,800–$211,400 taxable income
• IRMAA Tier 1 threshold: $218,000 MAGI (MFJ)² — a cliff that adds $1,948/year per person in Medicare surcharges

Most conversion analysis targets filling the 12% or 22% bracket annually — but no more than the IRMAA cliff allows. Converting $400,000 in a single year to "get it done" usually results in a large chunk taxed at 24–32%, while spreading the same amount over 10 years at 12–22% saves tens of thousands.

See the full year-by-year example and mistake list in Roth Conversions in Retirement: The 60–75 Window.

Strategy 4 — Harvest capital gains at 0%

Most retirees don't realize that the federal government taxes long-term capital gains at 0% for households with taxable income below $98,900 (MFJ) or $49,450 (single) in 2026.¹

Tax-gain harvesting is the deliberate act of selling appreciated shares in low-income years to realize gains while they're free — then rebuying the same (or similar) shares to step up your cost basis. The result: you convert a future taxable gain into a tax-free gain, permanently.

The critical caveat: realized gains count toward MAGI. A large harvest can push you over an IRMAA threshold ($109,000 single / $218,000 MFJ) two years later, triggering Medicare surcharges. Coordinate gain harvesting and Roth conversions in the same year carefully — you usually can't maximize both simultaneously. See the capital gains tax in retirement guide and IRMAA calculator.

Strategy 5 — Give charitably via QCD, not cash

If you're charitably inclined and over 70½ with an IRA, a Qualified Charitable Distribution (QCD) is the most tax-efficient way to give in retirement. You transfer money directly from your IRA to a qualifying charity. The amount — up to $111,000 per person in 2026⁴ — is excluded from gross income entirely.

Compare that to a cash donation: you withdraw from your IRA (ordinary income), get the charitable deduction, but only if you itemize — and only 60% of AGI. Most retirees take the standard deduction, so cash donations produce zero tax benefit. QCDs work regardless of itemizing, because the income never appears in the first place.

The three-layer tax advantage of a QCD vs. a cash donation:

1. Income exclusion: QCD amount doesn't hit your AGI at all.
2. SS taxation: Lower AGI reduces the taxable portion of Social Security (the "tax torpedo" explained in the Social Security tax calculator).
3. IRMAA tier: Lower MAGI may keep you in a lower Medicare surcharge bracket — worth $2,000–$5,000+/year per person.

If your RMD is $30,000 and you'd give $15,000 to charity anyway, a QCD for $15,000 reduces your taxable RMD to $15,000 — with full credit toward the year's RMD. Full mechanics at the QCD guide with tax savings calculator.

Strategy 6 — Stay below IRMAA cliffs

Medicare IRMAA surcharges are among the most underappreciated tax costs in retirement. A single dollar of MAGI above a threshold can add $974 to $5,844 per person per year in Medicare Part B surcharges, plus additional Part D surcharges.²

2026 IRMAA thresholds (based on 2024 MAGI):²

Key planning moves to manage IRMAA:

• Use QCDs to satisfy RMDs without raising MAGI.
• Use Roth withdrawals instead of traditional IRA when near a tier boundary — Roth doesn't count toward MAGI.
• Coordinate large Roth conversions carefully — they raise MAGI and the IRMAA penalty hits two years later.
• File an SSA-44 if your income dropped significantly from the look-back year (e.g., you retired in 2025 and are being assessed on your 2023 working income). Life-change events qualify.
• Avoid straddling tiers — if a Roth conversion of $80K would push you $2K over a tier, stop at $78K. The tier is a cliff, not a slope.

See the full bracket table and tier-avoidance strategies at the Medicare IRMAA calculator.

Strategy 7 — Coordinate Social Security timing with income sources

Social Security timing affects taxes in two distinct ways that most retirees don't fully account for:

Effect 1 — Every year you delay SS is a year the Roth conversion window is wider

If you delay claiming to 70, you can retire at 62–66 with essentially no Social Security income. During those years, your taxable income may consist entirely of IRA withdrawals or Roth conversions — giving you the full bracket width to convert at 12% rather than competing for bracket space with SS income. Delaying SS from 62 to 70 increases your benefit 77%, creates up to 8 additional years of maximum conversion opportunity, and locks in a larger SS income for life.

Effect 2 — SS income itself may be taxable, and the "torpedo" compounds with other income

Up to 85% of Social Security benefits are taxable if your combined income (AGI + half of SS) exceeds $34,000 (single) or $44,000 (MFJ).³ For most retirees with moderate traditional IRA balances, every additional dollar of IRA withdrawal effectively taxes $0.85 of Social Security — meaning the marginal rate on IRA withdrawals is actually 18.5% in a 22% bracket, not 22%. Strategies that reduce traditional IRA distributions (Roth conversions, QCDs, gain harvesting) also reduce the SS torpedo.

Use the Social Security claiming calculator to model how delay changes lifetime benefits and the SS tax calculator to see the torpedo effect at different income levels.

Putting it all together: what coordinated planning looks like

These seven strategies interact — each one changes the constraint set for the others. Here's a simplified illustration of how a retirement-income specialist might layer them for a 65-year-old couple with $2M in traditional IRA, $200K in taxable, $100K in Roth, delaying SS to 70:

Over 25 years, the combination of strategies can produce a difference of $200,000–$600,000 in lifetime tax paid — on identical savings and identical spending. The range reflects the value of professional scenario modeling: identifying the exact conversion amounts, the gain-harvest windows, and the IRMAA cliff distances that matter for your specific account balances, SS benefit, and state tax situation.

What advisors do that calculators can't

Each calculator on this site handles one variable at a time. A retirement income specialist models all seven strategies simultaneously, over a 20–30 year horizon, updated annually as tax law changes. They account for:

• Coordination between Roth conversions, capital gain harvesting, and IRMAA in the same year
• State income taxes — the optimal federal strategy can trigger unexpected state tax in some states
• Future legislative uncertainty — how OBBBA provisions interact with your plan under different scenarios
• RMD shock mitigation — running conversions long enough to actually reduce the 73-or-75 required distributions
• Estate optimization — whether to leave traditional IRA assets or Roth assets to heirs (inherited IRA 10-year rule), and how step-up basis affects the taxable-account decision
