What does TaxNinja do?

1. 1

   Step 1

   Gather your documents

   Whatever you received for the year. Photos and PDFs are fine.

   • 源泉徴収票 (withholding slip) from your employer
   • Receipts and invoices
   • Insurance, pension and iDeCo certificates
   • ふるさと納税 (hometown tax donation) receipts

   Step 2

   TaxNinja does the work

   Pick the tool that fits. Each one fills in the same return, and you confirm every amount.

   NinjaBot is with you in every tool

   Ask anything, give it your figures or a document, and it fills them in for you to confirm and shows you where to click.

   Katana

   Talk through your year or send photos, and Katana sets up your return.

   Step-by-step screens for income, deductions and your 源泉徴収票 (withholding slip).

3. Optional, before you print

   Have a 税理士 (licensed tax accountant) look first

   Want a professional to check your figures before anything is printed? Send them the draft.

   1. 1Download the draft package (PDF)
   2. 2Send it to your own 税理士 (tax accountant) to check
   3. 3Fix anything they flag in TaxNinja, then print the final version

   Step 3

   Print your filing package

   Your 申告書 (tax return form), pages 1 and 2 (第一表, 第二表), and the attachments, filled in on the official NTA layouts, with a checklist of what to sign and what to attach.

   Step 4

   Hand it in, your way

   The deadline is 15 March. A return that only claims a refund can be filed later too, for up to five years. Choose how you file:

   or

   File it yourself

   Take the package to your tax office (税務署). TaxNinja tells you which one and its address.

   Hand it to a 税理士 (licensed tax accountant)

   They check the printed package. Then:

6. Done

   Keep your copy (控え) with the reception stamp. A refund usually reaches your bank account within one to one and a half months.

TaxNinja prepares your return; you sign and file it. Not tax advice.
