Double-check your tax return for missed deductions and credits
Use AI as a second pair of eyes to spot missed credits and math errors, and use two AIs plus a professional for anything big.
1. Copy this prompt
Paste it into ChatGPT, Claude, Gemini or Grok (the free versions work), then replace the [highlighted brackets] with your details. Leave out account numbers and SSNs.
Act as a careful tax-prep reviewer (not a substitute for a professional). My situation for tax year [YEAR]: filing status [X], income sources [W-2/1099/etc.], dependents [ages], life events [LIST], approximate AGI $[X], state [STATE]. 1) List federal and state credits and deductions I should check, with the official IRS page for each, 2) list the documents I need, 3) after I paste my draft return summary, flag anything inconsistent or missing. Say clearly when you're uncertain.

Why this works
The problem: People miss credits (education, child care, saver's credit) and deductions, or make errors that cost money.
How AI helps: AI can quiz you about life events, list credits you might qualify for, and cross-check a draft return for inconsistencies.
