Steps

- Copilot returns structured rate data with thresholds and filing statuses
- Ask: "Generate a capital gains tax calculation function from these rates"
Example Prompt
Try this with Copilot using the Tax Reference tool
Fetch current long-term and short-term capital gains tax rates with income thresholds for all filing statuses. Return as structured JSON for use in my after-tax return calculator.
Tips
- Include the NIIT threshold in your data pull to build accurate high-income rate calculations
- Ask for both rate tables in one call — long-term and short-term — so comparison tools have both available
- Generate a gain classification function that returns the applicable rate given income, filing status, and holding period
