What is comprehensive income tax?
- Comprehensive income tax is the tax you pay on the income you earned through economic activities during the previous year. This includes income from POSTYPE as well as interest income, dividend income, employment income, business income, other income, and pension income. All such income is added together and taxed.
- Individual creators and individual business creators who earn income on POSTYPE must file and pay comprehensive income tax themselves during the filing period, regardless of the amount of income.
- If you are concerned about whether accumulating income and filing taxes may affect company policies on side jobs, or financial institution loan reviews, please contact the relevant institution directly.
- For questions related to tax filing, please contact the National Tax Service Hometax website or the National Tax Consultation Center (no area code needed, dial 126).
Filing and paying comprehensive income tax
Filing period
- Every year, for the entire month of May
Filing basis
- For the 2026 filing, the taxable income is the income for which a withdrawal was requested from January 2025 (actually deposited in February 2025) through December 2025 (actually deposited in January 2026).
-
If you have been withdrawing your income from POSTYPE every month through automatic withdrawal, the filing basis is the gross sales amount (income). Fees and value-added tax are excluded; instead of the final amount actually paid out, you must treat the full amount of income for which withdrawal was requested as sales and use that as the basis for filing your taxes.
- If income was generated on POSTYPE but you did not proceed with any withdrawals, it is not clearly defined from a tax perspective what basis should be used for filing comprehensive income tax. Unfortunately, POSTYPE is not authorized to provide tax advice for individual cases, and any such guidance would not have legal effect. Therefore, we recommend that you consult your local tax office or a nearby tax accountant’s office.
-
Go to [Income] > [Withdrawal history], select the year, and download your withdrawal history to view it at a glance.
- For example, if you request a withdrawal of 500,000 KRW on May 1, you will actually receive 445,000 KRW on May 10 after deducting a 50,000 KRW fee (10%) and 5,000 KRW value-added tax (10% of the fee). In this case, your income for April as a creator is 500,000 KRW, not 445,000 KRW.
