How do I check my tax return for mistakes with AI?

Jeremy Judkins's Grok Bot compared his 2025 return with his 2024 one and found his Cybertruck was being depreciated on a different schedule, leaving about $15,100 in deductions unclaimed. It walked him through fixing it in TurboTax, and he says it saved him about $2,500.

Steps

  1. Gather this year's draft return, last year's filed return and a list of assets you depreciate with dates and costs.
  2. Ask your AI to compare how each asset is depreciated across the two years and show the math both ways.
  3. Ask it to check nothing is claimed twice, like a vehicle that's depreciated and also listed under vehicle expenses.
  4. Have it list each difference with its dollar effect and the exact forms and lines to check.
  5. Make the edits yourself and confirm with IRS instructions or a tax professional before filing.

Here are this year's draft tax return and last year's filed return. For each asset I depreciate, compare the method, recovery period and remaining basis across both years, flag any change and show the math both ways. Check nothing is claimed twice, list each difference with its dollar effect, and tell me which forms and lines to check. Don't file or change anything.
