Sole proprietors in South Korea are subject to two main types of taxes: value-added tax (VAT) and income tax. Regardless of whether your business is profitable or not, it is crucial to fulfill your tax obligations.

VAT is applicable to most businesses, but there are some exemptions depending on the nature of your business activities. This includes considerations such as the purpose of your business, which can impact the portion of the income you retain. For example, certain services like translations may be exempt from VAT.

VAT filing for sole proprietors is conducted every six months. The standard VAT rate in South Korea is 10%, which is applied to the taxable value of your goods or services.

Income tax is another tax that sole proprietors must pay. Yearly income tax returns for sole proprietors are due on May 31st. The tax rate for income tax varies based on the amount of income earned. Here is a breakdown of the tax rates based on income brackets:

  • Up to KRW 12 million: 6%
  • KRW 12 million to 46 million: 15%
  • KRW 46 million to 88 million: 24%
  • KRW 88 million to 150 million: 35%
  • KRW 150 million to 300 million: 38%
  • KRW 300 million to 500 million: 40%
  • Over KRW 500 million: 42%


  • Full Control and Decision-Making – In a sole proprietorship, the owner have full control over and discretion over the company. They don’t need the approval of partners or shareholders to take independent actions or execute any idea.
  • Lower Costs – Compared to other business structures, creating and maintaining a single proprietorship in South Korea is typically less expensive. The owner won’t be required to pay additional fees for incorporating or fulfilling certain compliance requirements.
  • Direct Profits – The owner gets to retain every profit the company makes as its single owner. There is no requirement to distribute profits to partners or shareholders, allowing them to enjoy the financial benefits entirely.
  • Privacy – Another benefit of sole proprietorships is privacy. They are subject to fewer disclosure requirements than corporations. This implies that their financial and commercial interests can be private.
  • Easy Dissolution – The process of closing or dissolving a sole proprietorship is typically less complicated and time-consuming than winding up a corporation. If wanted, they have the liberty to quickly end activities and start new businesses.


  • Unlimited Liability – As a sole proprietor, all of the company’s debts and responsibilities are their own to bear. This implies that personal assets are in danger if the firm experiences financial setbacks or legal problems. It is essential to thoroughly evaluate and manage any potential risks connected to business operations.
  • Limited Access to Capital – Compared to other business structures, sole proprietorships may have trouble obtaining funds. Since the company only uses the owner’s personal funds or borrowing capacity, obtaining financing or luring investors can be more difficult. The potential for growth and expansion of the company may be hampered by this restriction.
  • Lack of Continuity – In a solo proprietorship, the owner is the heart of the business. The company may run into difficulties if the proprietor falls ill, becomes incapable of working, or dies. There is no independent legal entity, unlike companies, that can run the business on its own. The long-term survival of a single proprietorship depends on planning for business succession and enabling an easy transition.
  • Limited Specialisation – The owner might experience restrictions as a solo proprietor in terms of specific knowledge and expertise. Many different skill sets are generally needed to run a business, and as sole owners, they could have to manage multiple aspects of the company themselves. This can be challenging.
