Tax planning / PLANNING GUIDE

Make the tax conversation happen before the transaction.

Realized gains, business income, deductions, residency and coordinating investment decisions with tax advice.

THE PERIMETERReviewed September 19, 2026Guide · Questions · Checklist

A tax decision often begins outside a tax return: a sale, grant, relocation, distribution or charitable commitment. The useful question is which choices remain available before the event becomes irreversible.

Build an event map

List expected stock sales, option exercises, business transactions, retirement distributions and moves between states. Identify the owner, account and expected date for each event. Bring this map to a qualified tax professional before implementation.

Compare after-tax outcomes

Ask for scenarios that include federal, state and local treatment where applicable. Include the effect of other income and the possibility that timing changes a result. A strategy that reduces one tax can create another cost or a loss of flexibility.

Coordinate responsibilities

Have the investment advisor and tax preparer agree on what they will each model, execute and document. Confirm deadlines and assumptions in writing. Proposed legislation and news commentary are different from rules that apply to an actual transaction.

Four questions for a better conversation

  1. Which decisions need to be made before I sign, sell, exercise or move?
  2. What facts determine whether a particular tax treatment applies to me?
  3. How will withholding or estimated payments be coordinated?
  4. Who checks the transaction against the final tax return?
