Tax Services

Most clients fall into one or two categories based on how they earn, invest, or move.
Below are the most common drivers of tax complexity.

Equity Compensation

RSUs · ISOs · ESPPs

We handle basis adjustments, AMT modeling, QSBS eligibility, and capital gains planning for stock comp events.


This is for you if:

  • Your W-2 includes RSU income

  • You exercised ISOs or sold company stock

Year-End Tax Moves for Equity, Crypto, and Remote Work

There’s still time to act before December 31 — but not much.

If 2025 brought any financial changes — like selling stock, exercising options, moving across state lines, or realizing crypto gains — you may still have ways to reduce what you owe. But many tax strategies have strict year-end deadlines.



Common Triggers That Warrant Action Now:


  • Stock option exercises or RSU vesting: AMT exposure, 83(b) timing, basis tracking — all time-sensitive.

  • Significant crypto gains or losses: Loss harvesting and accurate 8949 filing depend on correct year-end treatment.

  • Moved states or worked remotely across borders: Split residency, income sourcing, and tax credits all require advance planning.

  • Secondary sales or startup exit: QSBS eligibility, installment treatment, and timing of recognition can impact liability.

  • Capital gains from investments: Harvesting losses, estimated tax adjustments, and donation strategies are on the table.
