Decoding Business Taxation in Korea: Handling the Financial Terrain with Knowledgeable Guidance

Updated: Dec 30, 2023

In the complicated landscape of business operations, one of the important aspects an entrepreneur must understand is taxation. Business taxation is more than just complying with legal regulations.

It’s also a strategic move that can impact the bottom line of your business.

In this blog, we will walk through the complications of business taxation in Korea, understand its intricacies, and stress the importance of guidance in handling this important aspect of financial management.


What is Business Taxation? How does it work in South Korea?

In the simplest terms, business taxation is the taxes that a business must pay to the government as a normal part of business operations.

In South Korea, business taxation encompasses a variety of taxes, including sales tax, income tax, turnover tax as well as acquisition tax and surtax. The tax landscape in Korea is dynamic due to the changes in laws and regulations, making it important for any business to stay informed and compliant with it.

Who is Liable to Pay Taxes in South Korea?

In South Korea, the National Tax Services handles all taxation matters, particularly when it comes to corporate taxation.

Two types of corporations are subjected to business tax in Korea

Domestic Corporations:

Domestic corporations operating in South Korea are obligated to pay corporate tax. This includes companies that have a head office, a main office, or a place of actual business management within the country.

The taxation applies to both Korean-based and foreign-based income. This broad scope ensures that all businesses operating within the national borders contribute to the tax revenue, fostering economic growth and stability.

Foreign Corporations:

Foreign corporations are also subject to corporate tax if they derive income from Korean sources, known as domestic source income. For a foreign corporation to be liable for corporate tax in South Korea, it must have its head or main office located in a foreign country. The focus on Korean-based income ensures that foreign businesses benefiting from the South Korean market contribute to the national tax revenue, even if their primary operations are based abroad.



How a Corporate Taxable Income is Determined?

The corporate tax liability is determined based on the net profits a business generates from its operations over one fiscal year. This includes income from both domestic and foreign sources for domestic corporations, and exclusively from Korean sources for foreign corporations. The National Tax Services utilizes a transparent and standardized process to calculate the taxable income, ensuring fairness and accuracy in the assessment.


What is the Minimum Tax for Businesses in Korea?

Corporate taxpayers have to pay a minimum tax, which is defined as the greater of 10% (if the tax base is KRW 10 billion or less, 12% on the tax base exceeding KRW 10 billion but not more than KRW 100 billion, 17% on the tax base exceeding KRW 100 billion) of the taxable income before certain tax deductions and credits pursuant to the STTCL or the actual CIT liability after certain deductions and credits under the STTCL.

This is calculated before certain deductions and credits. Small and medium-sized enterprises (SMEs) have a minimum tax of 7% based on their taxable income, and middle-market companies, also known as 'medium-scale companies,' have an 8% minimum tax rate for the first three years after disqualification as an SME and a 9% rate for the following two years.


Understanding the Local Income Tax in Korea for Businesses

Local income tax is a different kind of income tax with its own rules. For corporations, the rates vary based on the income. It's 0.9% for the first KRW 200 million, 1.9% for income between KRW 200 million and KRW 20 billion, 2.1% for income between KRW 20 billion and KRW 300 billion, and 2.4% for anything above that.


What are the Other Corporate Taxes in Korea?


South Korea enforces various taxes and duties on property, transactions, and gifts.

·   A capital registration tax of 0.48% (1.44% in Seoul) is imposed, and property taxes range from 0.1% to 4%.

·   Comprehensive real estate holding tax varies from 0.5% to 6%. Stamp duties apply to agreements, and a securities transaction tax of 0.35% (0.2% for listed shares, 0.1% for KONEX-listed shares) is charged on share transfers.

·   Acquisition tax rates for real estate, vehicles, and equipment range from 1% to 7%. The gift tax, ranging from 10% to 50%, applies when the property increases in value.


How a Knowledgeable Tax Professional Can Help Your Business in Korea?

So you must have understood the basics of the taxation system in South Korea.

However, you still need a knowledgeable tax professional to navigate the complexities of the tax system in the nation and comply with the local tax laws as well.  Having a professional tax consultant by your side helps with the current tax laws, and regulations, and an ability to apply them strategically to benefit the business. Seeking guidance from tax professionals, such as certified public accountants (CPAs) or tax consultants, becomes essential.

These experts bring a wealth of knowledge and experience to the table, ensuring that businesses not only meet their tax obligations but also optimize their financial position. From identifying eligible deductions and credits to implementing tax-efficient strategies, knowledgeable guidance is instrumental in mitigating risks and maximizing returns.

Strategic Tax Planning:

Effective tax planning is a cornerstone of sound financial management. It involves forecasting the company's financial activities and structuring them in a way that minimizes tax liabilities. Knowledgeable tax professionals can assist in identifying opportunities for tax savings, such as leveraging tax credits, deductions, and exemptions.

Furthermore, they can guide businesses in making informed decisions regarding investments, acquisitions, and other financial transactions to optimize tax outcomes. By aligning financial goals with tax strategies, businesses can enhance their competitiveness and resilience in the market.

Compliance and Risk Mitigation:

Tax laws are ever-changing, and compliance is non-negotiable. Knowledgeable tax professionals play a crucial role in keeping businesses abreast of regulatory changes, ensuring that they remain compliant with the latest tax codes. This proactive approach not only helps in avoiding penalties but also positions the business to take advantage of new opportunities and incentives.

Additionally, tax professionals contribute to risk mitigation by conducting thorough reviews of financial records and practices. Identifying and rectifying potential compliance issues before they escalate is a proactive measure that safeguards the business from legal and financial repercussions.

The Impact on Small Businesses:

While large corporations often have dedicated teams and resources to manage their tax affairs, small businesses may find themselves at a disadvantage due to limited resources. However, the impact of taxation on small businesses is equally significant. Knowledgeable guidance becomes even more critical for small businesses, where every financial decision can have a pronounced effect on the bottom line.


Decoding business taxation is a multifaceted challenge that requires a combination of knowledge, experience, and strategic acumen. Businesses that prioritize knowledgeable guidance in handling their tax affairs are better positioned to navigate the financial terrain successfully. From strategic tax planning to compliance and risk mitigation, the role of tax professionals cannot be overstated.

In an era of evolving tax laws and economic uncertainties, businesses must recognize the strategic importance of sound tax management. By partnering with knowledgeable tax professionals, businesses can not only meet their legal obligations but also optimize their financial position, ensuring long-term success and resilience in a dynamic business environment. It can benefit their corporate tax planning to a great extent.
