Categories of taxable revenues

Most kinds of revenues are subject to the Japanese Income tax, and only very few ones are exempt from the taxation. Commonly seen non-taxable revenues are capital gains from used goods in case they are sold after the sellers' daily use. Reselling of used goods by consumers has become popular the rapid spread of useful internet services. Meanwhile, gains from resale of goods purchased for the resale from the beginning, are taxable. The gains fall into the General Capital Gains.

Profits from receiving gifts from individuals and inheriting properties are not subject to the Income tax. Instead, they are subject to the Gift tax / Inheritance tax in accordance with the Inheritance Tax Act.

The following chart shows major categories of taxable revenues and calculation formula of the taxable amount.

"Employment Income deduction" and "Public Pension Income Deduction" is not well imaginable, I am afraid. They are mere estimated and provisional figures, taking various intentions into consideration in the long history. I will explain the detail of the "Employment Income Deduction" because employment income is the most common type of taxable revnues.

Employment Income Deduction
Total of Full-year salaries/bonuses Employment Income Deduction
~1,625,000yen 550,000yen
1,625,000yen ~ 1,800,000yen revenues amount × 40% - 100,000yen
1,800,000yen~ 3,600,000yen revenues amount × 30% + 80,000yen
3,600,000yen~ 6,600,000yen revenues amount × 20% + 440,000yen
6,600,000yen~  8,500,000yen revenues amount × 10% + 1,100,000yen
8,500,000yen~ 1,950,000yen

The range painted in blue in the following chart shows the amount of the Employment Earnings beyond the Employment Deduction amount, and the amount is taxable. The deduction amount increases as the Employment Earnings amount goes larger. But the deduction amount reaches the maximum when the earnings amount is 8.5 million yen and stay 1,950,000 yen after that. This means the proportion of the taxable range goes larger along with the earnings amount.

給与所得控除や公的年金控除はうまくイメージができないかもしれません。これらは、長い歴史のなかでいろいろな思惑を反映して設定された数値にすぎないからです。 給与所得は、もっとも一般的な所得区分ですので、給与所得控除について具体的に説明します。

年間の給与等の合計額 給与所得控除
~1,625,000円 550,000円
1,625,000円 ~ 1,800,000円 収入金額 × 40% - 100,000円
1,800,000円~ 3,600,000円 収入金額 × 30% + 80,000円
3,600,000円~ 6,600,000円 収入金額 × 20% + 440,000円
6,600,000円~  8,500,000円 収入金額 × 10% + 1,100,000円
8,500,000円~ 1,950,000円

給与収入の内で課税される部分の割合は、上表の形式で表現することができます。 青に塗られた部分、つまり給与の収入金額の内、給与所得控除額を超える部分が、課税対象となります。 給与所得控除額は、給与の収入金額が増えるにつれて増加しますが、年間の給与額が850万円となったときに限度額に達し、それ以降は1,950,000円のまま一定となります。つまり、給与額が増えるにつれて、課税される部分の割合も増えていくことになります。
