Explain a tax concept prompt
A copy-and-paste prompt for ChatGPT, Claude or Gemini that gets a professional explain a tax concept on the first try, plus the cheapest model that does it well.
What most people type
explain the difference between an LLC and an S corp for taxes, I make about 90k profit a year
It works, but the AI has to guess your country and state, current LLC tax classification and other income, so the first answer usually needs another round. The version below asks for exactly what a professional would deliver.
The better prompt
Explain the tax difference between an LLC and an S corp for my situation: I make about 90k profit a year. Context: [country and state], [current LLC tax classification, e.g. single-member LLC, or not yet formed], [self-employed income only or other income too], [filing status]. Cover: - How each is taxed (pass-through treatment, self-employment tax vs. payroll tax, and what an S corp election changes for an LLC). - A side-by-side comparison at about 90k profit. Show your math and state your assumptions, including a placeholder reasonable salary that I can adjust. Calculate the figures yourself rather than quoting rates you can't verify, and tell me which rates or thresholds I should check against current rules. - Extra costs and obligations of an S corp (payroll, separate tax return, state fees, bookkeeping) that could offset the savings. - Whether the S corp election is likely worth it at this income, and what would change the answer. - Questions to ask a CPA or tax professional. Format: a short explanation, then a comparison table, then a brief conclusion. This is general information, not tax advice. Don't invent specific rates or rules that depend on my location.
Replace the [brackets] with your details before you send it: country and state, self-employed income only or other income too, filing status.
