At The Money: Tax Management for Investors

December 31, 2025

Key Takeaways Copied to clipboard!

  • Tax management is a controllable priority for investors, offering guidelines within the current tax code that contrast with the unpredictability of market movements. 
  • Tax diversification across pre-tax (traditional 401k), after-tax (brokerage), and tax-free (Roth) accounts provides crucial flexibility, especially in retirement planning. 
  • Strategies like the Mega Backdoor Roth conversion allow high earners to significantly increase tax-free savings, while managing concentrated equity risk requires proactive planning around capital gains and potential deferral mechanisms like 351 exchanges.

Tax Management Priority

  • Key Takeaway: Tax management offers more short-term control than asset allocation or security selection because the current tax code provides defined rules.
  • Summary: Investors can control tax outcomes based on the existing set of rules, unlike market performance which is unpredictable. Tax management is a proponent of control because the tax code provides guidelines for the foreseeable future. This control allows investors to make a tangible difference in their tax liability.
Tax Diversification Buckets

  • Key Takeaway: Tax diversification requires holding assets across pre-tax, after-tax, and tax-free buckets to maximize flexibility, especially during retirement withdrawals.
  • Summary: The three primary tax buckets are pre-tax (like a traditional 401k), after-tax (brokerage), and tax-free (Roth). Lacking tax diversification means all retirement distributions could be taxable, removing flexibility. Planning ahead to diversify these buckets provides significant options when funds are needed later in life.
Mega Backdoor Roth Conversion

(00:05:56)
  • Key Takeaway: The Mega Backdoor Roth strategy allows high earners to contribute after-tax money up to the total 401k limit (e.g., $70k in 2025) and convert it to Roth for tax-free growth.
  • Summary: This strategy involves making after-tax contributions up to the annual limit, beyond standard employee/employer contributions, and then converting that after-tax money to Roth without incurring immediate tax. This creates tax-free growth, and the Roth portion can potentially be invested more aggressively since it is the last money touched. High earners should inquire with their CFO or HR about implementing this feature in their 401k plan.
Equity Compensation Tax Traps

(00:09:13)
  • Key Takeaway: Equity compensation like RSUs and options creates taxable income upon vesting or exercise, often leading to unexpected tax bills because recipients feel stock gains as paper wealth, not cash income.
  • Summary: RSUs are taxed almost like a cash bonus upon vesting, while options (NSOs and ISOs) involve a tax component on the spread between the strike price and the share’s value. A common trap is failing to account for the tax liability generated by stock compensation, leading to a large April tax bill. Proactive tax planning is essential to manage these non-cash income sources.
Managing Concentrated Stock Risk

(00:11:08)
  • Key Takeaway: Employees with highly appreciated, concentrated stock positions should strategically plan capital gains realization to mitigate concentration risk, potentially using direct indexing or 351 exchanges.
  • Summary: If a stock position grows large enough to cause anxiety over market fluctuations, diversification is necessary, even if it means paying capital gains tax. Long-term capital gains rates (around 20% plus NIIT) are often a reasonable price to pay to reduce concentration risk. Mechanisms like direct indexing can create tax losses to offset gains, or 351 exchanges can bundle concentrated stock into a diversified ETF, though basis remains the same.
Tax Deferral Mechanisms

(00:14:19)
  • Key Takeaway: Mechanisms similar to real estate’s 1031 exchange allow investors to defer capital gains by exchanging one appreciated security position for a diversified basket, though the low basis carries over.
  • Summary: These exchange mechanisms defer tax obligations, they do not eliminate them, as the original low basis is maintained in the new asset. If an investor continually defers gains until death, heirs receive a step-up in basis, effectively solving the deferred capital gain issue. This deferral strategy is popular given the long bull market creating large, low-cost basis positions.
2025 Tax Law Changes Review

(00:15:57)
  • Key Takeaway: The most significant aspect of the 2025 tax law changes is what did not change: scheduled tax rates were set to increase but were averted by a recent act, preserving current rates.
  • Summary: Had the recent tax bill not passed, tax rates were set to increase by 3-5% across the board, with the top rate potentially rising from 37% to 39.6%. Other changes focus on the deduction side, emphasizing timing deductions like charitable giving or SALT deductions to coincide with the client’s highest income years when those deductions are most valuable.
Integrating Tax and Estate Planning

(00:17:36)
  • Key Takeaway: Strategic Roth conversions are a key integration point between income and estate planning, allowing parents to pay income tax now at their potentially lower rate rather than burdening high-earning heirs with mandatory distributions.
  • Summary: Estate tax exemptions are high, but income tax planning is relevant throughout life and impacts generational wealth transfer. Under Secure Act 2.0, inherited IRAs face a 10-year depletion rule, meaning heirs must pay tax on pre-tax money at their potentially higher marginal rates. Parents can convert pre-tax assets to Roth, paying tax at their current rate (e.g., 24%) to shield heirs from a higher future rate (e.g., 37%).
Forward-Looking Tax Strategy

(00:19:29)
  • Key Takeaway: Effective long-term tax planning centers on timing income and deductions across one’s lifetime to pay tax when marginal rates are lower, rather than focusing solely on past performance.
  • Summary: The goal is to determine when tax can be paid at a lower rate than what might be faced in the future. This involves looking forward to strategically time income and deductions to take advantage of fluctuations in lifetime income and tax rates. These marginal timing differences compound significantly over decades.
