Why Claude? This tool was tested and engineered specifically for
Claude (claude.ai). In our testing across multiple AI platforms, Claude consistently produced the most accurate bracket-level tax calculations and correctly identified credit interactions that other platforms missed. The free version works well — just make sure to select the latest version of
Sonnet as your model. If you have a paid subscription, even better — use the most powerful model available. This tool also works with
Gemini and
ChatGPT, though results may be less precise.
Important: The AI output is an excellent preparation tool, not a replacement for professional advice. Bring your results to a qualified CPA, tax strategist, or Enrolled Agent for verification before making changes.
How this works: Start with the first tab (W-2, Retirement & Investments) — everyone fills that in. If you also have a side business or rental property, click those tabs and fill them in too. When you click Generate My Tax Analysis, the tool collects data from all sections you filled in and builds one complete prompt. You only need to copy and paste once.
