Tax planning is not an afterthought — it’s a core part of preserving and maximizing wealth, especially as you approach or enter retirement. For high-net-worth investors with $500,000–$5 million in investable assets, proactive tax optimization can meaningfully improve after-tax returns and preserve more wealth for income, legacy, and peace of mind.
Below are practical strategies tailored for investors like you — married couples, pre-retirees, and retirees who want to keep more of what they earn without chasing gimmicks.
Portfolio construction decisions are just one piece of the puzzle. Long-term results improve when investment strategy is coordinated with comprehensive tax planning for retirees, especially during the transition from accumulation to distribution.
2026 Long-Term Capital Gains Tax Rates & Thresholds
In 2026, long-term capital gains (on assets held more than one year) remain subject to 0%, 15%, or 20% federal rates, depending on taxable income. These thresholds are slightly adjusted for inflation:
| Tax Rate | Taxable Income (Single) | Taxable Income (Married Filing Jointly) |
|---|---|---|
| 0% | Up to ~$49,450 | Up to ~$98,900 |
| 15% | ~$49,451–$545,500 | ~$98,901–$613,700 |
| 20% | Over ~$545,500 | Over ~$613,700 |
These figures apply to federal capital gains tax — state taxes may also apply.
This structure means gains are marginally taxed (like ordinary income), and timing can dramatically affect your liability.
1. Asset Location — Put the Right Holdings in the Right Accounts
Asset location is the practice of placing investments in accounts based on how they’re taxed:
- Tax-inefficient assets (e.g., high-turnover mutual funds, REITs) belong in tax-deferred or tax-free accounts
- Tax-efficient assets (e.g., broad index ETFs) are often best in taxable accounts
- High-growth assets often go in Roth IRAs so future gains are tax-free
This strategy reduces the drag of taxes over time and is especially important for high-net-worth portfolios.
2. Tax-Loss Harvesting — Use Losses to Offset Gains
Tax-loss harvesting involves selling securities at a loss to offset realized capital gains. The IRS allows:
- Capital losses to offset capital gains dollar-for-dollar
- Up to $3,000 of excess losses against ordinary income annually
- Unlimited carryforward of unused losses to future years
The wash-sale rule prevents repurchasing identical securities within 30 days before or after the sale, but you can strategically swap into similar positions to maintain exposure. This works great with ETFs.
This is one of the most direct ways to reduce your current and future tax bills.
3. Long-Term Holding — Lower Your Effective Tax Rate
Holding assets longer than one year shifts gains into the long-term category, which often carries significantly lower rates than short-term gains — which are taxed as ordinary income.
This is a simple yet powerful discipline for reducing overall tax exposure, particularly for investors in or near retirement.
4. Charitable Giving & Donor-Advised Funds
Donating appreciated securities is highly tax-efficient:
- You avoid capital gains on the donated shares
- You generally receive a deduction equal to the fair market value
- Donor-Advised Funds (DAFs) allow you to “front-load” charitable giving in high-income years
If you’re age 70½ or older, Qualified Charitable Distributions (QCDs) let you give up to a set limit directly from an IRA to charity — reducing adjusted gross income (AGI) without itemizing. These can also lower Medicare IRMAA exposure if coordinated with income planning.
5. Coordinating Roth Conversions
Strategic Roth conversions shift assets from tax-deferred accounts to tax-free accounts. Done in lower-income years (for example, before Social Security and Required Minimum Distributions begin), this can:
- Lock in tax treatment at current (often favorable) brackets
- Reduce future RMDs, which can push income into higher capital gains and IRMAA brackets
- Provide tax-free income later in retirement
Because conversions increase Modified Adjusted Gross Income (MAGI), they can affect Medicare costs and surtaxes like the 3.8% Net Investment Income Tax (NIIT). Planning timing and staging is key — and part of a broader tax-efficient retirement strategy.

6. Managing the Net Investment Income Tax (NIIT)
High-net-worth investors often face the 3.8% NIIT on net investment income when MAGI exceeds certain thresholds (e.g., $250,000 for married couples filing jointly). This surtax can effectively raise your top capital gains rate to approximately 23.8%.
Strategies to manage NIIT include:
- Holding tax-efficient assets in tax-advantaged accounts
- Timing distributions and conversions
- Reducing MAGI through deductions and income sequencing
7. Estate and Legacy Planning
Estate strategies can significantly reduce tax burdens for beneficiaries:
- Step-up in basis at death eliminates unrealized capital gains for heirs
- Gifting strategies, including annual gift exclusions, reduce future estate tax exposure
- Irrevocable trusts and life insurance trusts can preserve wealth tax-efficiently
Well-structured estate planning prevents unnecessary capital gains and income taxes for the next generation.
8. Integrating Tax Planning with Income Sequencing
Tax planning does not happen in a vacuum. How you time distributions, RMDs, Social Security, IRA conversions, and capital gains interacts with:
A comprehensive plan considers these connections. For example, combining tax‐efficient withdrawal strategies with Guardrails for Retirement Income and How to Reduce IRMAA improves both cash flow and after-tax outcomes. Tax-efficient portfolio design becomes especially important once withdrawals begin, which is why it should be coordinated with overall retirement income planning.
