Feeling overwhelmed by complex tax codes and the ever-watchful eye of state authorities? If you’re an entrepreneur or digital nomad considering South Korea as your next base, you’re likely searching for a business structure that maximizes your freedom and minimizes bureaucratic friction. In 2025, South Korea’s Individual Business Owner (개인사업자, Gaein Saeopja) status offers a streamlined, data-backed solution for those seeking autonomy and tax efficiency.
Understanding Sole Proprietorship in South Korea: The Individual Business Owner

This status is widely accessible to both citizens and residents, allowing you to operate a business without forming a separate legal entity. Registration is straightforward and can be completed online or at local tax offices, making it a practical choice for agile entrepreneurs.

How the Individual Business Owner Status Works
As an Individual Business Owner, you can:
- Invoice clients directly under your name
- Register your business with the National Tax Service (NTS)
- Access a simplified tax regime if your annual sales are below 80 million KRW (≈$59,000)
Pro Tips for Tax Optimization in 2025
- Leverage the Simplified VAT Regime
Pro Tip: If your annual sales are under 80 million KRW (≈$59,000), you qualify for the 간이과세자 (Gani Gwaseja) regime. This means reduced VAT obligations and less paperwork. Register early to lock in these benefits for the fiscal year. - Monitor Your Income Bracket
Pro Tip: South Korea’s personal income tax is progressive, ranging from 6% to 45%. If your business is scaling quickly, plan ahead to avoid jumping into a higher bracket unexpectedly. Consider timing large contracts or expenses to optimize your annual taxable income. - Streamline Registration
Pro Tip: Registration can be completed online via the National Tax Service portal. This minimizes in-person bureaucracy and speeds up your launch.
Concrete Example: Digital Nomad in Seoul
Imagine you’re a freelance developer earning 60 million KRW (≈$44,000) in 2025. By registering as an Individual Business Owner, you:
- Qualify for the simplified VAT regime (since you’re under 80 million KRW)
- Pay personal income tax at the applicable progressive rate (well below the top 45%)
- Can invoice international clients directly, with minimal local red tape
This structure keeps your compliance burden low and your autonomy high—exactly what savvy entrepreneurs value.
