About VestingStrategy

We help tech professionals understand and optimize their equity compensation taxes. No jargon, no fluff—just clear, accurate, actionable guidance.

Our Mission

Equity compensation is one of the most valuable—and most misunderstood—parts of tech compensation. A single mistake on an 83(b) election or a misunderstanding of California's tail tax can cost tens of thousands of dollars.

VestingStrategy exists to bridge the gap between complex tax law and practical decision-making. We translate IRS publications and treasury regulations into guides you can actually use.

Our Principles

Accuracy First

Every guide is researched using primary sources: IRS publications, treasury regulations, and official government guidance. We cite our sources.

Global Perspective

Equity compensation crosses borders. We cover US federal, state-specific rules (especially California), and international tax treaties.

Built for Tech Professionals

Created by people who've navigated RSU vesting, ISO exercises, and 83(b) elections firsthand. We understand the complexity.

Legal Optimization Only

We promote legal tax optimization strategies. Tax evasion is illegal and never recommended. Always consult a qualified professional.
