Below is the main tax schedule for September in South Korea.
1.Withholding tax filing(9/11)
When you pay your employees a salary, it is your responsibility to deduct taxes from their salary before paying them.
*For example, if your employee has a contracted salary of 2,500,000 KRW, you must deduct 35,600 KRW for taxes, and pay your employee 2,464,400 KRW. The 35,600 KRW you deducted must be reported on a withhold tax return and paid to the tax office on behalf of your employees.
The deadline for filing the withholding tax return is the 10th day of the following month after the payment was made. So, if you paid salaries to your employees in Aug, you must file the withholding tax return by Sep10th.
It's important to understand that the requirement to file a withholding tax return is not limited to salary payments. Any payment that requires taxes to be withheld must be reported on the withholding tax return.
*For instance, if you paid a loyalty payment to a foreign entity, you must also withhold taxes and report the payment on the withholding tax return.
