Choosing Between Capital Gain Harvesting & Roth Conversions

Investors who hold highly appreciated positions or large pre-tax retirement accounts often face a similar challenge: how to reduce risk today while also improving their long-term tax outlook. Two strategies frequently rise to the top—realizing capital gains and converting traditional retirement assets to a Roth. Both can be powerful, but each accelerates tax payments in different ways.

The central question becomes how to manage the trade-off: is it more advantageous to recognize additional ordinary income, additional capital gains, or a blend of both?

A structured decision process helps clarify the path forward. When evaluating these strategies, several factors typically shape the outcome:

Key Considerations

  • Purpose and timing of future asset use. Whether the funds are intended for near-term spending, long-term growth, or legacy planning influences which tax costs make sense to accelerate.
  • Current tax bracket and sensitivity to added income. Additional ordinary income from a Roth conversion or extra capital gains can push a client into higher marginal brackets or trigger phaseouts.
  • Projected future income and tax expectations. Anticipated changes in earnings, required minimum distributions, or future tax law shifts can make paying taxes now more or less appealing.
  • Ripple effects on other financial areas. Higher income in the current year may affect Social Security taxation, Medicare IRMAA surcharges, and broader wealth transfer goals.

The decision matrix or flowchart can help visualize these trade-offs and guide toward a balanced approach that aligns with their risk tolerance, tax outlook, and long-term objectives.
