FixKit AIHome / Use case
โI want to get my tax return mostly ready before I file or see my preparer.โ
AI can gather income and deduction figures from your documents and fill a worksheet for you or your preparer to review. Check this year's rules โ not tax advice. You file it.
Using these documents [list, IDs blacked out], build a tax worksheet for [year]: each income item, deduction and credit, with the source document for every number. List items that need a decision or more paperwork. Note which rules I should double-check for this year. Not tax advice โ don't file or submit anything. Stop after the worksheet.
Fill in the [brackets]. Each prompt says when the AI should stop, so it doesn't wander off.

Black out account and card numbers before sharing anything. Never give an AI your bank password โ export statements instead. AI drafts; you approve and send. Not financial, legal or tax advice.
