Individuals who earn income are obligated to pay personal income tax, and due to the diverse sources of these earnings, the law has classified income (assessable income) into various categories to ensure fairness. The most appropriate methods of tax calculation are then determined based on these categories. Currently, the Revenue Code classifies assessable income into 8 categories, as follows:
1. Type 1 Income: Income derived from employment, including
2. Type 2 Income: Income derived from professional services or from employment duties or positions, including
3. Type 3 Income: Goodwill, rights or other benefits, annuities, or income that is in the nature of annual income resulting from inheritance, other legal transactions, or court judgment.
4. Type 4 Income: Interests, dividends, profit shares, capital reductions, capital increases, benefits from stock transfer, etc.
The law, in many cases, allows the choice to pay tax by the withholding tax method instead of combining with other income as per the general principle. This could lead to tax savings for individuals who are required to pay tax at a higher rate than the withholding tax rate.
5. Type 5 Income: Money or other benefits received from renting out properties, defaulting lease-purchase contracts, or defaulting installment sale contracts whereby the seller has repossessed the sold property without having to return the money or benefits already received.
6. Type 6 Income: Income derived from a liberal profession, such as law, medicine, engineering, architecture, accounting, creative arts, or other professions as designated by a royal decree.
7. Type 7 Income: Income derived from contract work in which the contractor must invest by providing significant assets in addition to the tools.
8. Type 8 Income: Income derived from business, commerce, agriculture, industry, transportation, real estate sale, or other activities not specified in income types 1 to 7.
