Brian described the need in plain English: a 2025 federal, Ohio and Columbus refund estimate for a married couple filing jointly with one child. Claude Code asked clarifying questions and for permission to search the web for current tax tables. It then scaffolded a Vite, React, TypeScript and Tailwind app with a calculator module for each jurisdiction.
It produced a working single-page app in one sitting. It takes W-2, interest, dividend and capital gains inputs, updates refunds live, shows charts, and saves to local storage. The author did not report checking the numbers against a real return.
The author still plans to have the CPA prepare the actual return. He treats the tool as a planning estimate only, and he saved the $300 quoted for the estimate.
Build me an interactive tax refund calculator using this year's official tax tables and brackets, where I can input my income, filing status, and deductions to estimate my refund or owed amount. Make it a simple web page or script I can run locally, and stop once I can enter numbers and get a correct estimate.
An app built with Claude Code extracts vendor, date, total, tax and line items from receipts, including foreign-currency ones at historical exchange rates, for freelancers and small businesses.
