Quarterly estimates with all 50 state brackets, NIIT, safe-harbor guidance, and wash-sale flagging — so April never ambushes you.
Simulation Only · Advanced & PremiumTradeCraft runs a quarterly estimated-tax simulation on your realized net P&L: all 50 state brackets plus federal, filing-status aware, with Net Investment Income Tax and IRS safe-harbor guidance built in. It exists to answer one question all year long: how much of this is actually mine?

Trading the same names repeatedly? Advanced plans get wash-sale risk alerts when a loss looks like it may be disallowed; Premium adds the full wash-sale detail table — every flagged pair, dates, and amounts, so nothing surprises you in February.
Brackets change; the simulator keeps up. The built-in tax-bracket updater fetches current federal and state brackets so estimates always use the current year's numbers.
Why: it's a simulation, and it says so — in the app and in the legal terms. Plan your withholding; let your CPA file.
Every plan includes the full journal, unlimited accounts, and 10 AI grades a day — no API key needed.
