Simplifying Taxation for Foreign Employees in Korea: Understanding NET Payment Contracts

In the dynamic world of global business, cross-border mobility of employees has become a norm. Many companies send their employees abroad on assignments, and South Korea is no exception. For foreign employees stationed in Korea, one common practice is the adoption of NET payment contracts. Let’s delve into the concept of NET payment contracts and how they simplify the tax landscape for both employers and employees.

Understanding NET Payment Contracts

A NET payment contract is an agreement in which the employer takes on the responsibility of paying all taxes and social insurance contributions associated with an employee’s income. This means that the employee receives their salary “NET” of all deductions, hence the term NET payment. In South Korea, where complex taxation rules can pose challenges, such contracts offer a streamlined solution for foreign employees.

Benefits for Foreign Employees

Foreign employees, especially those on expatriate assignments, often find themselves grappling with the intricacies of a new country’s tax system. The adoption of NET payment contracts by companies eases this burden significantly. Here’s how:

  1. Simplified Tax Obligations: With a NET payment contract, the company becomes the “withholding agent.” This means they withhold the necessary taxes and social insurance contributions from the employee’s gross salary before disbursing the NET salary. As a result, foreign employees are relieved from the responsibility of managing their own tax payments.
  2. Predictable Income: Employees receive a fixed NET salary, as the company takes care of the tax calculations. This predictability enhances financial planning and ensures that employees are not taken by surprise with unexpected tax obligations.
  3. Avoiding Double Taxation: In the case of expatriate assignments, where tax obligations may exist both in the home country and the host country, NET payment contracts often help avoid double taxation by ensuring proper tax credits and deductions are applied.

Benefits for Employers

Employers also stand to gain from adopting NET payment contracts:

  1. Attracting Foreign Talent: Simplified tax obligations make the company’s employment package more attractive to foreign professionals, especially in a competitive market.
  2. Minimized Administrative Burden: By taking on the responsibility of calculating and paying taxes, the administrative burden on HR and finance departments is significantly reduced.
  3. Enhanced Compliance: NET payment contracts ensure accurate and timely tax payments, reducing the risk of compliance issues for both the company and its employees.

How Does It Work?

In a NET payment contract, the company calculates and withholds the employee’s social insurance premiums, income tax, and any other mandatory contributions. These amounts are then paid to the relevant authorities on behalf of the employee. This approach streamlines the tax process and ensures compliance with Korean taxation laws.


NET payment contracts offer a win-win situation for both foreign employees and their employers in South Korea. By shouldering the tax burden, companies provide their employees with a simpler and more transparent way of handling their financial obligations. For foreign professionals navigating a new tax system, NET payment contracts serve as a valuable support mechanism, allowing them to focus on their work and personal growth without unnecessary stress about tax complexities.
