RSU vs ISO vs NSO: Tax Implications for PMs at Google, Meta, and Amazon in 2026

Mistakes to Avoid

Bad: “I’ll just accept the RSU offer and ignore the ISO option.” Good: Explain how exercising ISOs within the same tax year avoids the 37 % ordinary‑income bracket, referencing the Google ECF.

Bad: “I assume Meta’s RSU tax is the same as the federal rate.” Good: Cite Meta’s TCC credit that reduces California tax from 8 % to 5 %, and show the $5 k after‑tax gain.

Bad: “I’ll wait to exercise Amazon NSOs until the share price peaks.” Good: Show the AMT liability on a 15 k‑share grant at $1,200 per share, and the cash‑flow risk if the price drops 10 % before the 90‑day window closes.

FAQ

What is the key tax difference between an ISO and an RSU for a Google PM?
ISO income is taxed at exercise, potentially at the 15 % long‑term capital gains rate, while RSUs are taxed as ordinary income at vest (22 % federal in 2026). The ISO can double after‑tax cash if exercised within the same year.

Can a Meta PM reduce state tax on RSUs?
Yes. Meta’s Total Compensation Calculator applies a tax‑gross‑up credit that trims the California tax from 8 % to 5 %, adding roughly $5 k after‑tax on a $150 k RSU package.

Is there any scenario where Amazon’s NSO is preferable?
Only when a PM has > $100 k liquid cash to cover AMT and can lock in a low share price before the 90‑day exercise window. Otherwise the AMT exposure erodes the benefit.amazon.com/dp/B0GWWJQ2S3).
