Supported Forms
These are the core Japanese income-tax forms and schedules we reference across the FreeTaxJapan experience. The names are real, the layout is polite, and the old A/B vocabulary is still hanging around in collective memory.
Current terminology
People still say Form A and Form B, but current individual income tax filing centers on the unified return and attached schedules. Tax season keeps its old nicknames longer than it keeps some actual forms.
Core return
The primary filing flow revolves around the numbered return tables and the right schedules.
Schedules
Medical expenses, donations, business income, and breakdown sheets all travel with the return.
Legacy vocabulary
We acknowledge the old terms so people do not have to fight both forms and memory at once.
A quick working list of the forms FreeTaxJapan talks about most often for annual filing.
| Form / table | Name | Typical use | Category |
|---|---|---|---|
| 第1表 / 第2表 | Final return main sheets | Used by most filers to report income, deductions, tax credits, and the final settlement. | Core return |
| 第3表 | Return for separated taxation | Used when certain gains or income items are taxed separately from ordinary income. | Core return |
| 第4表 | Return for loss reporting | Used when carrying losses or reporting situations that need the fourth table. | Core return |
| 青色申告決算書 | Blue return bookkeeping statement | Used by blue-return filers to summarize business income and expenses. | Attachment |
| 収支内訳書 | Income and expense statement | Used by many sole proprietors who prepare the white-return business statement. | Attachment |
| 医療費控除の明細書 | Medical expense deduction statement | Attached when claiming the medical expense deduction. | Attachment |
| 寄附金控除に関する明細書 | Donation deduction statement | Used for donation deductions, including the furusato nozei paperwork stack. | Attachment |
| 所得の内訳書 | Income breakdown sheet | Used to list income sources when the main return needs a cleaner supporting breakdown. | Attachment |
Historically, individual filers often talked about 確定申告書A and 確定申告書B. Current filing materials center on the unified return instead. We keep the old words nearby so nobody has to pretend they never heard them from an employer, parent, or accountant in 2019.
Practical tip
Salary income alone is usually calm. Business income, medical deductions, and furusato nozei receipts are how the paperwork begins multiplying.
