Tax Scenario Lab · master calculator · 2025

See your tax picture.
Then play "what if."

A real 2025 tax estimate — capital gains, every major phase-out by filing status, passive-loss rules, and a "which status should you file?" check. Then toggle what-ifs and watch your bill move. No bank upload. The free checkup behind PilePilot.
