Pro Tip

Remembering the term

Think of 累進 (ruishin) as 'accumulating steps'—each step (income bracket) increases the rate, like climbing stairs.

Gold Rule

Progressive vs. Regressive

Progressive taxation (累進課税) increases with income. Regressive taxation (逆進性) decreases with income. Proportional taxation (比例課税) stays flat.

Word Origin

課税 (kazei, taxation) + の (no, possessive) + 累進性 (ruishinsei, progression). 累進 (ruishin) combines 累 (accumulate) and 進 (advance), indicating a step-by-step increase.

Usage Notes

Used in academic, legal, and financial contexts. Often contrasted with 比例課税 (proportional taxation) and 逆進性 (regressive taxation). The term emphasizes the structural property of the tax system rather than the act of taxation itself.
