High-Net-Worth Retiree Tax Strategies to Preserve Wealth

Tax strategies for high-net-worth retirees in 2026 come down to a single discipline: controlling which dollars appear on your tax return and in which year. The One Big Beautiful Bill Act kept the top individual rate at 37% and raised the federal estate and gift tax exemption to $15 million per person, which reshapes the calculus for conversions, charitable giving, and wealth transfers.¹ The strategies below work together; a Roth conversion done in isolation can raise your Medicare premiums two years later, and a charitable gift structured the wrong way can miss the deduction entirely.

What Changed for 2026

The 37% top rate applies to taxable income above $640,600 for single filers and $768,700 for married couples filing jointly. The 24% bracket runs up to $201,775 single and $403,550 joint, which becomes the practical target ceiling for many conversion decisions. The standard deduction is $16,100 single and $32,200 joint, high enough that most retirees will not itemize without deliberate bunching.¹

One OBBBA change deserves attention up front. A new charitable deduction floor disallows the portion of contributions below 0.5% of adjusted gross income. On $1 million of AGI, the first $5,000 of charitable gifts produces no deduction. This makes qualified charitable distributions and donor-advised fund bunching more valuable than they were, because QCDs bypass the deduction system entirely and larger DAF contributions push well above the floor.

The federal estate and gift tax exemption is $15 million per individual and $30 million per couple using portability, with a 40% rate on amounts above the exemption.² The annual gift tax exclusion is $19,000 per recipient.³ Roughly a dozen states impose their own estate or inheritance taxes at thresholds as low as $1 million, so the federal exemption is not the whole story.

Roth Conversions in the Pre-RMD Window

The years between stopping work and starting Social Security or required minimum distributions are the single most productive tax planning window a high-income retiree has. Taxable income falls, and lower brackets sit empty. Filling them with conversion income moves money from a traditional IRA, where it will eventually come out as ordinary income under RMD rules, into a Roth IRA, where qualified withdrawals are tax-free and there are no lifetime RMDs.

The mechanic is a bracket target. A married couple could convert enough to reach the top of the 24% bracket at $403,550 in taxable income and stop there. Going into the 32% bracket can still be defensible if projected RMDs would land there anyway, or if you plan to relocate from a no-tax state to a high-tax one. Run the projection both ways: tax paid on the conversion today against tax paid later on the same dollars pulled as RMDs.

Pay the conversion tax from a taxable brokerage account, not from the IRA. If you convert $200,000 and withhold $50,000 from the IRA to cover the bill, only $150,000 reaches the Roth, and the withheld amount is a distribution that loses its future tax-free growth. Cutting a check from outside the retirement account keeps the full amount compounding tax-free.

Each conversion carries its own five-year clock. Converted amounts withdrawn within five years by someone under 59½ can trigger a 10% early withdrawal penalty on the portion that was taxable at conversion. The clock starts January 1 of the conversion year.⁴ Every conversion needs to be reported on Form 8606 to track basis.⁵

Done consistently, conversions shrink the traditional IRA balance that will later drive RMDs, which in turn shrinks Medicare surcharges, Social Security taxation, and net investment income tax exposure. That is where the compounding value shows up.

Managing RMDs With Qualified Charitable Distributions

Required minimum distributions from traditional retirement accounts begin at age 73 and are calculated from IRS life expectancy tables.⁶ A $4 million traditional IRA at 75 produces roughly $150,000 in taxable RMDs each year, all as ordinary income, and that income drives Medicare premiums, Social Security taxation, and the NIIT.

A qualified charitable distribution redirects up to $111,000 per year from an IRA directly to a qualifying charity once you reach 70½. The transfer satisfies your RMD but never enters adjusted gross income.⁷ That distinction matters. A regular charitable deduction reduces taxable income but not AGI, so it does nothing for IRMAA, Social Security thresholds, or the NIIT calculation. A QCD reduces AGI itself.

The transfer has to move directly from the IRA custodian to the charity. Take the distribution first and then write a personal check to the charity, and the whole distribution is taxable regardless of intent. Custodians will not fix this after the fact.

Qualified Longevity Annuity Contracts

A QLAC purchased inside an IRA removes up to $210,000 from the balance used to calculate RMDs, with payments deferred up to age 85.⁸ The trade-off is liquidity: those dollars are committed to a contract, and death before payments begin leaves the payout to the contract’s death benefit terms. QLACs fit best as longevity insurance layered on top of other assets that cover near-term needs.

Donor-Advised Fund Bunching

A donor-advised fund lets you concentrate several years of charitable giving into one tax year, take the full deduction that year, and grant the money out to charities on your own schedule later. For a household that has drifted below the $32,200 standard deduction, this is often the only way to get any tax value from ongoing giving.

Consider a couple giving $40,000 a year with no other significant itemizable deductions. They lose the tax benefit every year because they take the standard deduction. Contribute $200,000 to a DAF in one year instead, and the deduction clears both the standard deduction and the new 0.5% AGI floor. In the following four years, the DAF distributes grants while the couple takes the standard deduction. Same total giving, higher total deductions.

Funding the DAF with appreciated stock rather than cash amplifies the result. You deduct fair market value up to 30% of AGI, and neither you nor the DAF pays capital gains on the built-in appreciation. Cash contributions are deductible up to 60% of AGI. Amounts above the applicable ceiling carry forward for up to five years.

Cutting the 3.8% Net Investment Income Tax

The NIIT adds 3.8% on top of ordinary rates and applies to the lesser of net investment income or the amount modified AGI exceeds $200,000 single or $250,000 joint. Those thresholds have not been indexed since the tax took effect in 2013.⁹ Most high-net-worth retirees are well past them, so the full 3.8% applies to every dollar of investment income.

Municipal bond interest is exempt from federal income tax and excluded from the NIIT calculation. A retiree in the 35% ordinary bracket who also owes NIIT faces a 38.8% combined marginal rate on taxable interest. A municipal bond yielding 3.5% delivers the equivalent of 5.7% taxable at that combined rate.

Tax-Loss Harvesting

Selling losing positions in taxable accounts offsets realized gains dollar for dollar, which reduces both the capital gains bill and the NIIT base. After gains are absorbed, up to $3,000 of remaining losses offsets ordinary income, and anything left carries forward indefinitely. The wash sale rule disallows the loss if you buy a substantially identical security within 30 days on either side of the sale. Swapping into a similar but not identical fund, such as moving from one broad index fund to a different broad index fund, keeps you invested without tripping the rule.

Material Participation

Income from a trade or business in which you actively work is not net investment income under the statute. The IRS recognizes several tests for material participation; the most straightforward requires more than 500 hours of work in the activity during the year. Retirees who manage rental real estate or stay involved in a family business can potentially move that income out of the NIIT base by meeting this threshold. Contemporaneous time records matter; the IRS challenges material participation claims routinely.

Timing Around Medicare IRMAA

Medicare Part B and Part D premiums step up through income-related monthly adjustment amounts. For 2026, the first tier begins at modified AGI above $109,000 single and $218,000 joint, and the top tier applies above $500,000 single or $750,000 joint. At the top tier, the Part B surcharge alone runs $487 per person per month, close to $11,700 per year for a married couple.¹⁰

IRMAA uses your tax return from two years earlier, so 2024 income sets 2026 premiums. That look-back cuts both ways. A large Roth conversion in 2024 can push premiums up in 2026, while a deliberately low-income year can hold premiums down for two years afterward. QCDs help here because they reduce the AGI that IRMAA reads; ordinary charitable deductions do not.

If a life-changing event such as retirement itself produces a sharp income drop, Form SSA-44 lets you ask Social Security to use a more recent year’s income instead of the two-year-old return.

Reducing Tax on Social Security Benefits

Up to 85% of Social Security benefits become taxable once combined income (AGI plus nontaxable interest plus half your benefit) exceeds $34,000 single or $44,000 joint.¹¹ Those thresholds have never been indexed for inflation, and virtually every high-net-worth retiree hits the 85% ceiling.

You cannot avoid the 85% inclusion at high income levels, but you can shape which income sources feed combined income. Roth IRA withdrawals do not appear in AGI and do not enter the combined income calculation. QCDs pull down the AGI component. The planning window is again the pre-Social Security years, when Roth conversions can shrink the traditional IRA balance that would later produce RMDs stacked on top of taxable benefits.

Where to Hold Which Investments

Account location changes the outcome of every strategy above. Assets that generate frequent ordinary income, such as high-yield bonds, REITs, and actively managed funds, belong inside traditional IRAs and 401(k) plans where the annual tax drag disappears. Tax-efficient holdings like broad-market index funds and municipal bonds fit better in taxable brokerage accounts, where you control realization timing and, for munis, keep the interest out of both regular tax and the NIIT.

Roth accounts do their best work holding the highest-expected-growth positions, because the tax-free treatment compounds most on the assets that appreciate the most. This flips the conventional advice for retirees whose Roth balances are large enough that the location decision meaningfully changes 20- or 30-year outcomes.

Moving Wealth Before the Exemption Could Change

The $15 million per-person exemption is generous by historical standards, but it is not permanent protection against a future Congress lowering it. Irrevocable transfers made now can lock in current exemption levels.²

Annual Gifts and the Step-Up in Basis

The $19,000 annual gift tax exclusion moves that amount per recipient each year with no use of lifetime exemption and no reporting below the limit. Gift splitting doubles it to $38,000 per recipient for a married couple.³

The choice of what to give during life and what to hold until death turns on the step-up in basis. Assets held at death receive a new cost basis equal to fair market value, erasing unrealized capital gains for heirs.¹² Stock with a $100,000 basis and a $1 million value gifted during life carries that low basis to the recipient. Held until death, the $900,000 of appreciation is gone from the tax base. The working rule: give cash and low-appreciation assets during life, hold highly appreciated assets for the step-up.

Grantor Retained Annuity Trusts

A GRAT transfers future investment growth to beneficiaries at a low gift tax cost. You place assets in an irrevocable trust, take annuity payments back over a fixed term, and any growth above the IRS Section 7520 rate passes to beneficiaries free of gift and estate tax. The 7520 rate in early 2026 sits at roughly 4.6%.¹³ A concentrated stock position or private business interest with strong growth prospects is a natural fit. The catch: dying during the trust term pulls the assets back into your estate as if the GRAT had never existed.

Spousal Lifetime Access Trusts

A SLAT moves assets out of one spouse’s taxable estate while giving the other spouse indirect access through trustee distributions. Couples use SLATs to lock in the $15 million exemption without giving up all practical access to the funds. Two risks structure the planning. If the beneficiary spouse dies first, indirect access ends. If both spouses set up mirror-image SLATs, the IRS can invoke the reciprocal trust doctrine and undo the estate tax benefit. Attorneys differentiate the trusts on trustees, distribution standards, and beneficiaries to avoid that outcome.

Irrevocable Life Insurance Trusts

Life insurance proceeds are income-tax-free to beneficiaries, but they land in your taxable estate if you owned the policy at death. A $5 million policy could generate $2 million in estate tax at the 40% rate. An ILIT owns the policy from the start, receives premium payments funded by your annual gifts to the trust, and collects the death benefit outside your estate. Transferring an existing policy into an ILIT requires surviving three years afterward; having the trust buy a new policy avoids the waiting period. Annual premium gifts qualify for the $19,000 exclusion when the trust grants beneficiaries withdrawal rights, commonly called Crummey powers.³
