A Guide to Tax Benefits for Start-up SMEs in South Korea
This guide provides an overview of the tax reduction and exemption benefits available to newly established Small and Medium-sized Enterprises (SMEs) in South Korea. Understanding these benefits can significantly impact your company's financial planning.
Who is Eligible for Start-up Tax Benefits?
To qualify for tax reductions as a start-up SME, your company must meet at least one of the following four conditions. Please note that for conditions 1 and 2, your business must also fall within a specific range of eligible industries.
1. SMEs Founded Outside the Seoul Metropolitan Area Overconcentration Control Zone
If your company was established outside of the designated "Overconcentration Control Zone" in the Seoul metropolitan area, it might be eligible for tax benefits.
- Youth Start-up SMEs: If the founder/representative of the corporation was between 15 and 34 years old at the time of establishment and is the largest shareholder, the company is classified as a Youth Start-up SME. Even if established within the Overconcentration Control Zone, some tax reductions may apply if the annual revenue is below 80 million KRW.
2. Companies Certified as a "Venture Company" within 3 Years of Start-up
If your company is officially certified as a "Venture Company" (벤처기업) within its first three years, it can receive significant tax benefits. A key requirement is that your R&D expenses must be at least 5% of your total revenue for the fiscal year. The tax benefits for Venture Companies are generally broader than for regular start-up SMEs, so obtaining this certification early is highly recommended.
3. Companies in "New Growth Service Industries"
This category applies to businesses operating in specific, government-designated "New Growth Service Industries" (신성장 서비스업). If your company has multiple business lines, the primary business is determined by which one generates the most revenue.
Examples of New Growth Service Industries:
- Computer programming, system integration, software development, and information services (excluding news providers).
- Creative and arts-related services, film and video production, and broadcasting.
- Engineering, professional design, and advertising (specifically copywriting and design).
- Publishing, R&D, and certain vocational training institutions.
- Logistics, tourism, and other sectors designated by the Ministry of Economy and Finance.
4. Certified "Business Incubation Center Operators"
A Business Incubation Center Operator (창업보육센터사업자) is an entity whose main purpose is to support start-ups by providing facilities, space, and business/technical support. To qualify, the operator must meet specific requirements regarding facilities, equipment, professional staff, and a business plan approved by the Ministry of SMEs and Startups.
Tax Benefits for Start-up SMEs
Eligible start-ups can receive the following tax benefits:
Corporate and Income Tax Reductions
For the first five years of business, eligible companies can receive a significant reduction in their corporate tax (for corporations) or income tax (for sole proprietors).
- Start-up SMEs: A 50% tax reduction for 5 years from the date of establishment.
- Venture Companies: A 50% tax reduction for 5 years from the date of venture certification.
Additional Reductions for Increased Employment
Companies can receive an additional tax reduction if they increase their number of full-time employees compared to the previous year. The additional reduction is calculated as half of the employment growth rate (e.g., a 20% increase in employees gives an additional 10% tax reduction). This additional reduction is capped at a maximum of 50%.
Summary of Tax Reduction Rates
The following table summarizes the tax reduction rates based on the type of company and its location.
