Check this year's tax return against last year's for missed deductions (AgentPlays original)

AgentPlays original prompt based on a real case posted on X on Oct 13, 2026: Jeremy Judkins's Grok Bot noticed his 2025 return depreciated his Cybertruck on a different schedule than his 2024 return, leaving about $15,100 in deductions unclaimed, and walked him through fixing it in TurboTax. He says it saved about $2,500. This template asks for the same year-over-year check. No results claimed.

Review my tax return for missed or inconsistent deductions before I file.

What I have:
- This year's draft return: [attach PDF or export]
- Last year's filed return: [attach PDF]
- Assets I depreciate: [vehicle or equipment, purchase date, cost, business-use %]
- Tax software I use: [name and version]

Do this:
1. For each depreciated asset, compare this year with last year: method, recovery period, convention and remaining basis. Flag any change (for example, a switch from a declining-balance schedule to straight-line) and show the math both ways.
2. Check that nothing is counted twice, such as a vehicle that is depreciated and also claimed under vehicle expenses.
3. List each difference with its dollar effect on my deductions, and say what you're unsure about.
4. Tell me exactly which forms and lines to check or change in my tax software, step by step.

Don't file or change anything. I'll make the edits myself and confirm with a tax professional if the amount is large.
