What is Comprehensive Income Tax?

Comprehensive income tax is a tax calculated by summing up all incomes earned by an individual during the year. This tax is levied progressively based on the individual's income level, and filing occurs from May 1 to May 31 every year.

Individual incomes include earned income, business income, capital gains, interest income, and dividend income. Since the tax rates and calculation methods vary for each type of income, a proper understanding is essential.

If you fail to file or miss out on certain items, you may incur additional tax penalties, so be cautious. Therefore, it is crucial to prepare in advance for safe filing.

Filing Preparation Process

To file comprehensive income tax, you first need to prepare the necessary documents. Key documents include income withholding certificates for earned income, proof related to business income, and proof of expenditures.

Additionally, it is advisable to organize your income data from the previous year in advance. Since tax calculations depend on the type of income, organizing materials helps in efficient filing.

Utilizing digital tools when organizing data can make it even more convenient. For example, using image conversion and compression tools to organize receipts, and PDF conversion tools to manage documents easily.

Tax Calculation by Income Type

Tax calculations need to be done separately for each type of income. For earned income, taxes are deducted from salaries, while for business income, net income is calculated by deducting expenses from revenue.

Capital gains tax is calculated differently based on the duration of asset holding, while different tax rates apply for interest and dividend income. These calculations are crucial for determining comprehensive income tax.

For example, if you have business income, utilizing tax software to systematically manage income and expenses can be very helpful.
