控除 (kōjo) is a noun meaning 'deduction' or 'withholding', often used in tax contexts. The phrase is typically followed by 額 (gaku, 'amount') or 申告 (shinkoku, 'declaration') in formal usage.
控除 (kōjo) refers to the concept of deduction, while 控除額 (kōjogaku) refers to the specific amount deducted. For example, 医療費控除 (medical expense deduction) is the category, and 医療費控除額 is the calculated amount.
This phrase is specific to income tax. For other taxes (e.g., consumption tax), use different terms like 消費税の控除 (though consumption tax deductions are rare in Japan).
所得税 (shotokuzei) = 'income tax' (所得 'income' + 税 'tax'); 控除 (kōjo) = 'deduction' (控 'withhold' + 除 'exclude'). The phrase combines these terms to describe a tax reduction mechanism.
This term is commonly used in official tax filings and discussions about personal finance in Japan. It is distinct from 税額控除 (tax credit), which directly reduces tax liability rather than taxable income.
