Tax Reference

ChatGPT explains capital gains tax rates in plain language and applies them to your specific transaction. It walks through the difference between short and long-term treatment, explains the 0%, 15%, and 20% rate tiers, and tells you what a specific sale will cost in tax before you execute it.

Steps

Once connected (see setup above), use the Tax Reference tool:

  1. Ask: "What are the current long-term capital gains rates?"
  2. ChatGPT returns rates with income thresholds by filing status
  3. Ask: "What rate applies to my situation?" and provide income and filing status

Example Prompt

Try this with ChatGPT using the Tax Reference tool
I am single with $95,000 of income and am planning to sell shares with a $40,000 gain. What capital gains rate applies? What would I owe? And what would I owe if I had only held them 11 months instead of 13?

Tips

  • Ask for the current 0% capital gains threshold — many people in lower brackets pay nothing on long-term gains
  • ChatGPT can explain what counts as a "qualified dividend" in context with capital gains treatment
  • Ask for the net investment income tax threshold separately — it catches higher earners who thought they were at 15%
