This one gives Claude 39 local tax tools covering federal brackets, state comparisons, quarterly estimates, credits (EITC, CTC, AOTC), deductions (itemized vs standard, SALT caps), retirement accounts, AMT, capital gains, and self-employment tax. Everything runs on your machine with zero network calls or data persistence. You can ask it to calculate your federal tax with dependents, compare filing statuses, check W-4 withholding per paycheck, evaluate Backdoor Roth strategies, or run full federal plus state tax scenarios. Built for the 2025 tax year with One Big Beautiful Bill Act changes baked in. Includes detailed disclaimers since it's estimates only, not professional advice.
