Clear Up Tax-Filing "Don't-Knows" with AI

Tax filing is an area with high jargon and procedure walls. AI helps with understanding the system and sequencing prep, but finalize the actual filing with the official tool (e-Tax) or a tax accountant.

Typical Questions AI Can Answer

  • "I'm an employee but side income exceeds 200k yen. Is filing needed? What documents?"
  • "Difference between medical-expense deduction and the self-medication tax system?"
  • "Furusato-nozei one-stop vs tax filing—which should I use?"
  • "General thinking on what can/can't be an expense?"

Usage Pattern

I'm [employee/sole proprietor/freelancer]. This year [side job/started a business/high medical expenses]. Give the procedures and documents needed for tax filing, step by step for a beginner. Also list official info to reference at each step.

Always Observe

  1. Don't swallow tax/deduction figures: AI's calculation errs. Recalculate in the NTA's filing-form preparation corner
  2. Don't input personal info: My Number/account/name unneeded. Tell only the situation
  3. Confirm the latest year's system officially: tax rules change yearly; AI's knowledge may be old
  4. Take uncertain issues to a tax accountant: tax-saving schemes/business determination are an expert's domain

Prep Is the Biggest Bottleneck

Asking "make a needed-documents checklist" and "steps to organize receipts by this classification" greatly eases the prep stage that's more troublesome than filing itself.
