Assumptions and limits2026 tax year · checked Oct 26, 2026
Figures used
- Recorded vest matches a scheduled one within
- 31 days
- Tax years
- 2026 brackets for every year
Assumed
- Future vests use today’s share price and exchange rate unless a what-if says otherwise.
- Vests are wages in dollars on the vest date for a US taxpayer, whatever currency the stock trades in.
- Future years use this year’s brackets and limits.
- One job: Social Security is figured as if it were your only one.
Not modeled
- Withholding on each vest and what you’ll owe at tax time; the RSU planner does that for one year.
- Selling shares: capital gains, cost basis and the dollar basis of foreign-currency shares.
- Foreign tax on vests, tax treaties and the foreign tax credit.
- Stock options and private-company equity (coming next).
