Ignoring Tax Planning is Like Leaving the Faucet Running - Tax Strategy Is a Multi-Year Discipline, Not a Once-a-Year Event
Key Takeaways
- Effective tax planning focuses on lifetime marginal tax rates, not just annual refunds
- Coordinating income timing, investment choices, asset location, and withdrawal sequencing can materially improve after-tax wealth outcomes
- Legislative thresholds, deduction limits, and estate exemptions should be reviewed regularly
A Thoughtful Tax Strategy is Designed To:
- Coordinate taxable income across retirement phases, including the years before and after Social Security and RMDs
- Position assets efficiently for both retirement income and legacy goals
- Avoid Medicare IRMAA surcharges when possible
- Reduce exposure to the Net Investment Income Tax (NIIT)
- Select the right income-producing investments and manage capital gains strategically
- Implement tax-loss harvesting as an ongoing, portfolio-wide process, rather than a one-time, year-end discipline, to improve after-tax results over time
Why Tax Strategy Requires a Long-Term Perspective
Tax returns document what has already happened. Tax strategy, by contrast, is the process of managing income, deductions, and portfolio structure over time to improve after-tax outcomes. Ignoring that process is a bit like leaving the faucet running—small amounts of water may not seem like much in the moment, but over time the waste adds up. In the same way, unplanned taxes can quietly erode otherwise strong investment results. In this context, tax planning becomes a multi-decade discipline, not a once-a-year filing task.
The Retirement Tax Shift Most Investors Don’t See Coming: When Social Security and RMDs Begin
Retirement income planning is not static. The years before Social Security and Required Minimum Distributions (RMDs) often look very different from the years after both begin. Failing to adjust the strategy across these phases can create several unintended tax consequences.
The Shift After Social Security and RMDs Begin
Once Social Security starts and RMDs are required, retirees typically move from a period of flexible, controllable income to one where much of their income becomes mandatory and less adjustable.
This Shift Can Create Several Planning Challenges:
Unexpectedly High Marginal Tax Brackets
RMDs are taxed as ordinary income. When combined with Social Security, investment income, or pensions, retirees may find themselves in higher brackets than anticipated—sometimes higher than during their working years.
Medicare IRMAA Surcharges
Higher reported income can trigger Income-Related Monthly Adjustment Amount (IRMAA) surcharges, increasing Medicare Part B and Part D premiums. These surcharges are based on income from prior years, meaning poor planning today can increase healthcare costs down the road.
Reduced Ability to Control Taxable Income
Before RMDs, retirees can choose how much to withdraw from different account types. After RMDs begin, a portion of income becomes mandatory each year, limiting flexibility and making tax planning more reactive.
Larger Tax Burdens on Surviving Spouses
When one spouse passes away, the survivor typically moves from married filing jointly to single filing status. This often results in higher marginal tax rates at lower income levels, especially if large RMDs are still in place.
Bottom Line
The years before Social Security and RMDs begin often provide one of the most valuable tax planning windows in retirement. During this period, retirees typically have more control over their taxable income and can take steps to reduce future RMDs, manage tax brackets, and protect the surviving spouse from unnecessary tax burdens. Even if that window has already passed, there are still strategies available to help manage taxes and improve after-tax outcomes later in retirement
Looking Beyond Yield: Why After-Tax Income Matters More Than Stated Income
Many investors focus on the stated yield of an investment and how much income it produces. But in retirement or high-income years, what matters far more is the after-tax yield and how that income affects your overall tax situation.
Not all income is taxed the same. Two investments with identical yields can produce very different after-tax results depending on how that income is classified and how it interacts with your tax brackets, Medicare premiums, and long-term planning goals.
The Spectrum of Investment Income
Investment income generally falls into several tax categories, each with different implications.
- Tax-Free Income
- Tax-Efficient Income (Return of Capital)
- Qualified Dividend Income (QDI)
- Fully Taxable Ordinary Income
Why After-Tax Yield Isn’t The Only Consideration:
The impact goes beyond the immediate tax cost. More taxable income can:
- Push you into a higher marginal bracket
- Increase taxation of Social Security
- Trigger IRMAA surcharges on Medicare premiums
- Reduce eligibility for certain deductions or credits
This is why sophisticated planning focuses on after-tax income and bracket management, not just stated yield.
Bottom Line
Not all income is created equal. The type of income an investment produces—and how it interacts with your tax brackets, Social Security, and Medicare premiums—can have a greater impact than the stated yield itself. A thoughtful investment strategy focuses on after-tax income and overall tax efficiency, not just the headline yield.
Mutual Funds vs. ETFs: Capital Gain Efficiency
Many investors overlook the structural tax differences between mutual funds and ETFs.
Mutual Funds
- May distribute capital gains annually
- Investors owe taxes even if they didn’t sell shares
- Gains are triggered by portfolio turnover or redemptions
This can create:
- Unexpected tax bills
- Loss of control over timing of gains
ETFs
- Generally more tax-efficient due to their in-kind redemption mechanisms
- Typically avoid distributing capital gains
- Allow investors to control when gains are realized
Bottom Line
Over time, this structural difference can result in meaningfully higher after-tax returns in taxable accounts.
Tax-Loss Harvesting: Ongoing Process, Year-End Exercise… or Not at All
Why Many Investors Never Benefit from Tax-Loss Harvesting
Some advisors rely on standardized, cookie-cutter models built with mutual funds or ETFs. These structures often lack the individual positions and flexibility needed to realize losses strategically. As a result, even when markets are volatile, there may be few or no opportunities to harvest losses, and the potential tax benefit is never captured.
Tax-loss Harvesting is Often Marketed as a Value-add, But the Implementation and Portfolio Structure Determine How Effective it Actually is.
Traditional Year-End Harvesting
Even when tax-loss harvesting is offered, it is often implemented as a once-a-year exercise.
Many advisors:
- Harvest losses only at year-end in November or December
- Make limited adjustments before tax reporting deadlines
This approach:
- Misses opportunities earlier in the year
- Relies on market timing late in the year
SMA Limitations: Not Always Designed for Active Harvesting
Some separately managed accounts (SMAs) advertise tax management, but the reality varies.
In many cases:
- SMAs are not actively harvesting losses throughout the year
- Harvesting only occurs if the advisor requests them
- This review typically happens in November or December or not at all
As a result, the tax management may function more like a year-end clean-up rather than a proactive, continuous process.
Continuous Tax-Loss Harvesting Strategies and “Tax Alpha Decay”
Some specialized SMA strategies are designed to harvest losses continuously. While this approach can be effective early on, it introduces another issue known as tax alpha decay.
Over time:
- The largest harvesting opportunities occur in the early years
- Future loss opportunities decline
- The incremental tax benefit diminishes
However, the additional fee for the tax-managed strategy often remains, even as the tax benefit decreases or disappears.
A More Flexible Approach: Continuous, Custom Tax-Loss Harvesting
With a custom portfolio approach:
- Individual positions are monitored throughout the year
- Losses are harvested when opportunities arise
- Harvesting occurs across the entire portfolio, not just one sleeve
This approach can:
- Capture more opportunities during market volatility
- Offset gains from other investments
- Improve after-tax returns over time
- Avoid the extra overlay fees associated with SMA structures
The Bottom Line
Tax-loss harvesting can be a valuable planning tool, but the portfolio structure and implementation approach matter.
- Some portfolios are too rigid to harvest losses at all
- Others only harvest once per year
- Some tax-managed SMAs experience declining benefits over time
A flexible, custom, tax-aware portfolio allows for ongoing harvesting opportunities and more consistent after-tax outcomes.
Managing Concentrated Stock Positions with a Low-Cost Basis
Many investors accumulate significant wealth in a single stock, often through a long career, equity compensation, or early investment success. Over time, that position can grow to represent a large portion of their net worth, frequently with a very low cost basis.
While this may reflect strong past performance, it also introduces several planning challenges:
- Elevated portfolio concentration risk
- Large embedded capital gains
- Limited ability to diversify without triggering taxes
- More complex income and retirement planning decisions
Selling the position outright may create a significant tax bill, but holding it indefinitely can leave the portfolio overly exposed to company-specific risk.
Strategic Approaches to Managing Concentrated Stock
- Staged or Systematic Sales
Rather than selling the entire position in one transaction, a more strategic approach is to:
- Sell portions of the stock over multiple years
- Coordinate sales with lower-income years
- Offset gains with harvested losses
- Manage exposure to higher tax brackets and NIIT
This approach helps smooth the tax impact and allows for gradual diversification.
- Hedging Strategies
In some cases, investors may want to reduce downside risk without immediately selling the stock.
These approaches can help:
- Limit downside exposure
- Preserve upside potential
- Create time to plan a more tax-efficient exit
- Provide income if needed
- Building a Complementary Custom Portfolio
Instead of viewing the concentrated position in isolation, the broader portfolio can be designed to balance the risk of the core holding.
This may involve:
- Reducing exposure to similar sectors or factors
- Emphasizing diversification across industries, geographies and asset classes
- Constructing a custom portfolio designed to complement the concentrated position
The goal is to create a more balanced overall allocation while allowing the investor to manage the low-basis stock strategically.
- Charitable Gifting of Appreciated Shares
For charitably inclined investors, donating appreciated stock can be one of the most tax-efficient ways to reduce concentration.
Benefits may include:
- Avoiding capital gains tax on the donated shares
- Receiving a charitable deduction for the fair market value (subject to limits)
- Reducing overall portfolio concentration
Integrating the Strategy into a Broader Tax Plan
Managing a concentrated position is not just an investment decision—it is a tax and financial planning exercise.
Key considerations include:
- Marginal tax brackets
- Net Investment Income Tax (NIIT)
- IRMAA thresholds
- Charitable goals
- Estate and legacy planning
Bottom Line
A concentrated stock position with a low-cost basis requires careful planning. Rather than making a single large decision, many investors benefit from:
- Staged, tax-aware sales
- Hedging strategies to manage risk
- Custom portfolios designed to complement the position
- Charitable gifting of appreciated shares
With the right approach, it is possible to reduce concentration risk, manage taxes, and improve long-term after-tax outcomes.
Charitable Planning as a Tax Strategy
Charitable giving can be integrated into a broader tax strategy rather than treated as a year-end decision.
Common approaches include:
Donor-Advised Funds (DAFs)
- Allow a deduction in the contribution year
- Enable grants to charities over time
- Useful for “bunching” deductions in high-income years
Gifting Appreciated Securities
- Avoids capital gains taxes on donated assets
- Provides a deduction for fair market value (subject to limits)
Qualified Charitable Distributions (QCDs)
- Available starting at age 70½
- Allow direct IRA transfers to charities
- Can satisfy part or all of RMDs without increasing taxable income
For affluent households, charitable planning often intersects with estate and legacy strategies.
Estate and Gift Planning Considerations
With the federal estate exemption currently elevated, many families are evaluating:
- Lifetime gifting strategies
- Trust structures
- Inter-generational wealth transfers
- Charitable legacy vehicles
Although most estates may not be subject to federal estate tax under current law, state-level estate taxes and future legislative changes remain important considerations.
Tax strategy should therefore align:
- Retirement income planning
- Gifting strategies
- Estate structure
- Long-term family objectives
The FINAL Bottom Line
Tax preparation records what has already occurred. Tax strategy shapes what comes next.
For many households, the most meaningful planning opportunities come from:
- Managing marginal tax brackets over time
- Coordinating portfolio structure with tax characteristics
- Sequencing retirement withdrawals thoughtfully
- Integrating charitable and estate planning decisions
When tax strategy is treated as an ongoing process rather than a once-a-year event, it can play a significant role in preserving and growing after-tax wealth over time.

Investing involves risk including the potential loss of principal. No investment strategy can guarantee a profit or protect against loss. Mutual fund values will fluctuate with market conditions and it may not achieve its investment objective. ETFs trade like stocks, are subject to investment risk, fluctuate in market value, and may trade at prices above or below the ETF's net asset value (NAV). Upon redemption, the value of fund shares may be worth more or less than their original cost. ETFs carry additional risks such as not being diversified, possible trading halts, and index tracking errors.
