所得比例減税の導入により、高所得者ほど税負担が重くなる仕組みが採用された。
With the introduction of proportional income tax reduction, a system was adopted where higher earners bear a heavier tax burden.
Commonly used in discussions about progressive taxation systems or economic policies aimed at income redistribution.
所得比例減税 is different from 定額減税 (flat-rate tax reduction), where the same amount is deducted regardless of income. The proportional system adjusts the reduction amount based on income level.
When discussing 所得比例減税, always clarify whether it refers to a reduction in tax rates or tax amounts, as both can be proportional to income but are implemented differently.
所得 (income) + 比例 (proportion) + 減税 (tax reduction). The term combines three legal/financial terms to describe a specific tax policy mechanism.
This phrase is typically used in formal economic or legislative contexts. It is not a colloquial expression and is usually found in policy documents, news reports, or academic discussions about taxation.
