What is global income tax?
- Global income tax is the tax you pay on the income you earned from economic activities over the past year. This includes income from POSTYPE as well as all income generated from interest income, dividend income, employment income, business income, other income, and pension income, which are all combined and taxed together.
- Individual creators and individual business creators who earn income on POSTYPE must file and pay global income tax directly during the global income tax 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 the review process for bank loans, please contact the relevant institutions directly.
- For questions related to tax filing, please contact the National Tax Service Hometax website or the National Tax Consultation Center (dial 126 without an area code).
Filing and paying global income tax
Filing period
- Every year, during the month of May
Filing basis
- For the 2026 filing year, the income subject to filing is the income for which withdrawal was requested from January 2025 (actually deposited in February 2025) to 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 your gross sales (income). Fees and value-added tax are excluded; instead of the final paid amount, you must treat the full amount of income requested for withdrawal as sales when filing your taxes.
- If you have earned income on POSTYPE but have not requested a withdrawal, the tax standard for how you should file global income tax is not clearly defined. Unfortunately, POSTYPE is not authorized to provide tax advice for individual cases, and any such guidance would not have legal effect. Please contact your local tax office or a nearby tax accountant’s office for detailed advice.
-
You can view everything at a glance by going to [Income] > [Withdrawal history], selecting the year, and downloading your withdrawal history.
- For example, if you request a withdrawal of 500,000 KRW in income on May 1, a fee of 50,000 KRW (10%) and value-added tax of 5,000 KRW (10% of the fee) will be deducted, and 445,000 KRW will be deposited on May 10. In this case, the creator’s sales amount for April is 500,000 KRW, not 445,000 KRW.
