Estimate your income tax liability with bracket calculations, deductions, and a take-home pay summary.
The prompt
Copy this prompt and paste it into Claude, Cursor, ChatGPT, Codex, or any AI tool connected to Hatchable via MCP.
Build an income tax estimator. Users enter: gross annual income, filing status (Single, Married Filing Jointly, Head of Household), state (for state tax), standard or itemized deductions (with input fields for mortgage interest, charitable donations, state taxes paid, medical expenses), and pre-tax contributions (401k, HSA, IRA). Calculate federal tax using current brackets, state tax (simplified flat rates by state), FICA (Social Security + Medicare), and total tax. Display: effective tax rate, marginal tax rate, take-home pay (monthly and annual), and a breakdown pie chart of where each dollar goes. Compare the impact of different deduction strategies. Finance-professional design. Deploy it on Hatchable when done.
