Income concept

The concept of income is an argument about what income is. Since the introduction of the income tax, it has shown various developments.

There are several ways to think of income that is subject to income tax, as described below. Today, of the threeInclusive income conceptAre dominant, while in European countriesRestrictive income conceptThe idea ofGermany,FranceIn that case, the gain on the transfer of shares is exempt from tax. In Northern European countries, focusing mainly on the inefficiency of the concept of comprehensive income, investment income and labor income are separated and the former is taxed proportionally and the latter isProgressive tax rateApplyDual income taxHas been adopted.

Restrictive income concept

The idea is that taxable income is limited to that obtained from repetitive activities, and that accidental or temporary income is not taxed. One of the so-called acquisition-type income concepts.

Industrial revolutionSince then, the independent movement of capital (Capital cycle) As a resultwage,profit,interest,dividend,RentAs a result, continuous and recurring profits have come to be produced. These were reliable and stable tax sources, and they were easy to grasp, so they encouraged the establishment of income tax. Based on this background, the theory that only income obtained from activities that repeat and focus on sources that generate profits (Income source theory) Is born. This income source theory is based on the theory of national income from the 19th century to the beginning of the 20th century.Germany(German Empire) Was revolved around.

Income tax based on the concept of restricted income is classified according to the source of income, and different tax rates and amounts are levied on each income.Classification income taxA type of tax that calculates net income by the source of income (such as United Kingdom) and sums them upComprehensive income tax(Prussia and pre-war Japan that referred to it).

Consumable income concept

The idea is that taxable income is the portion of income that is profitable from consumption. Income is measured by the total amount of a person's consumption over a period of time. While excluding savings from income, consumption by borrowing is also included in income.John Stuart Mill,Irving FisherIt is based on the theory of, and has a certain theoretical usefulness, such as being advocated by Fischer and Kaldor and still having strong support among economists.

The income tax (consumption-type/expense-type income tax, expenditure tax) that adopts the concept of consumption-type income tax isIndia,Ceylon(CurrentSri Lanka), but it did not take root. This is due to inequity caused by exclusion of savings, difficulty in grasping consumption/determining aristocrats, and deviation from common sense.

However, since the expenditure tax is similar in content to the general consumption tax, it can be seen that it is replaced by the value-added tax as a general income tax.

Inclusive income concept

Advocated by German financial scholar Georg von SchanzNet asset valuation theoryBeginning with the concept developed by American Hague (Robert M. Haig) and Simons (Herry C. Simons).Shantz-Haig-Simons concept, Taking the initials of Hayg and Simon'sHS conceptAlso known as[7][8].. The economic gain that increases the tax-bearing power is all the increase in net assets, which is the idea that it is income, and is expressed by the formula "income = accumulation + consumption". This is one of the so-called acquisition-type income concepts. Temporary and accidental gains also become income,inheritanceIs also regarded as income (inheritance taxreference).

The concept of comprehensive income conforms to the demand for fair burden (principle of burden according to tax burden),Welfare stateSince it was an income concept that was suitable for, it was widely supported. Comprehensive progressive income tax, which adopts the concept of comprehensive income, makes it possible to apply and tax all income with one progressive tax rate table, and has a national finance procurement function.Redistribution function,Economic adjustment function・The resource redistribution function can be enhanced.[9].

On the other hand, there are problems, and in reality, unrealized gains and imputed income should be subject to taxation, but it is difficult to capture or evaluate them and in many cases they are not subject to taxation. Is one of the gains of realizationCapital gainWill not be taxed if not realized[10].. Also, in the United States during the economic stagnation of the 1970s, the concept of comprehensive income tax is clear in theory, but in the actual grasp of taxation, the ambiguity of the concept cannot be dispelled and it is difficult for tax authorities to grasp income. Yes, it was criticized for its limitations. For example, it was extremely difficult to grasp income in the underground economy, and the sense of unfairness in income taxation spread in American society. Since the 1980s, the tax rate will be uniform and the tax procedure will be simplified and clarified.Flat taxThe debate about the tax bill has increased[11].

Japanese income tax

Japan's income tax is the taxable standard of total income,Retirement incomeAmount of money,Forestry incomeThere are three amounts. This is based on comprehensive income tax, but realizes separate income tax on retirement income and forest income.

Taxpayer of income tax


The calculation methods for each of the 10 types of income listed below are defined. Therefore, the result of the calculation method is the income tax amount. Hereinafter, the income tax law will be referred to as “law”.

Among these, interest income, dividend income and real estate income are asset-based income, and salary income and retirement income are labor-based income. Business income and forest income are said to be a combination of asset income and labor income. Both wealth-based income and labor-based income fall under homeostasis. In addition, transfer income and temporary income correspond to temporary income. Miscellaneous income refers to income that does not fall under any of these nine types of income.

Tax exempt income

a formula

Income tax adopts a comprehensive taxation system, which calculates income tax by totaling various annual income amounts and is calculated as follows.[15].

(Business income) + (Real estate income) + (Interest income) + (Dividend income) + (Salary income) + (Miscellaneous income) = Ordinary income

(Ordinary income) + (Short-term capital gains) + (Long-term capital gains + Temporary income) x 1/2 = Total income amount

 とTaxation standardAfter calculating, apply the income deduction.

(Total income amount)-(Income deduction amount) = Total taxable income

 After calculating, of income taxProgressive tax ratemultiply.

(Taxable gross income amount) x tax rate-(tax deduction amount) + (Special reconstruction tax)-(Withholding tax amount) = Tax return

 The special reconstruction tax amount will be levied from 2013 (25) to 2037 (Reiwa 19).Tax rate is 2.1%[16].

(Declared tax amount)-(Planned tax amount) = Income tax amount paid

Deductions and tax rates


Income tax deductions are divided into the following forms.

  • Classification by what can be drawn
    • Deductions (US): What can be deducted from the amount of income
    • Tax credits (US: Tax Credits): Tax credits that can be deducted by a certain amount from the tax amount calculated by multiplying the taxable income amount by the tax rate
  • Classification by nature
    • Human deduction: Human factors (spouse,SupportCan be deducted by
    • Physical deduction: Other than personal deduction

The types of deductions are mainly classified into income deductions and tax deductions (for convenience,Resident taxAbout)).

tax rate

For example, when the income amount is 700 million yen, the required tax amount is as follows.

 700 million yen (taxable income amount) x 0.23 (tax rate) --63 yen (quick deduction amount) = 6,000 yen (income tax) 
 In addition, a special reconstruction income tax of 20,400 yen (≈ 97 yen x 4,000%) will be added.

Separate taxable incomeIf there is, the tax rate will be calculated by applying the following tax rates to the separated taxable income instead of adding them up to the total taxable income[18].

  • (Amount of taxable forest income × 1/5) × Above tax rate × 5

    • (Amount of taxable transfer income, etc. pertaining to general stock, etc.) × 15%
    • (Amount of taxable dividend income on listed stocks, etc.) × 15%
    • (Amount of taxable miscellaneous income related to futures transactions) × 15%
