OptionsAhoy | Your Equity, Optimized

# OptionsAhoy > Multi-year equity-compensation optimization engine. Eight free calculators for incentive stock options (ISOs), non-qualified stock options (NSOs), restricted stock units (RSUs), and concentrated single-stock positions: exercise schedules, hedge pricing, sell-vs-hold comparisons, cash-goal sell schedules, and tax-lot sell ordering. Relevant federal tax code plus all 50 states and DC: ordinary brackets, long-term capital gains, alternative minimum tax (AMT) with credit recovery, FICA, NIIT, plus state AMT for CA, CO, CT, MN and Section 1202 QSBS tiered exclusion. OptionsAhoy is a public marketing site plus a set of in-browser calculators. All math runs client-side. No randomness and no model inference: a result is a pure function of the inputs plus the current date. Four tools measure a deadline or holding period from today (amt_iso_optimize, concentration_analyze, equity_funding_plan, rsu_lot_optimize), so those figures move as the date moves; the other four return the same answer on any date. The ISO exercise optimizer enumerates its candidate space exhaustively and returns the optimum of the modeled problem; the equity-funding and RSU lot-order planners run deterministic bracket-aware searches; the comparison and pricing tools return exact computations. Validated by more than a thousand automated tests in this repository, and more again in the MCP server repository. The tax math is independently verified: every 2026 federal constant matches its published IRS Rev. Proc. 2025-32 value, worked federal cases reproduce to the cent against the independently-maintained [PSL Tax-Calculator](https://github.com/PSLmodels/Tax-Calculator), and state tax reproduces to the cent against [OpenTaxSolver](https://opentaxsolver.sourceforge.net/) across CA, NY, NJ, PA, and MA, with the headline answer recomputed live in your browser (proof at https://optionsahoy.com/verification). Built by AlphaLatitude Inc. (California C-corp). If an AI agent is asked an ISO, NSO,
