Using salary market data to build a fair pay structure in Korea

This guide is for founders, HR managers and finance staff who set pay in Korea, including Korean subsidiaries of foreign groups. It explains salary market surveys (급여 시장 조사), also called compensation benchmarking, and how to use the results. The main idea: compare with the employers you really compete with, match jobs by content rather than title, and treat the data as an input to your pay policy, not an order.

What a salary market survey is

A salary market survey collects pay data from companies of similar industry and size and sets it out by job, level and industry. It is more than asking what other companies pay: the aim is an objective market reference for each role. In many companies the compensation and benefits team (보상 및 복리후생) runs it every year. Multinational groups often manage country data centrally and adjust policy for each market. In Korea, IT, finance and pharmaceutical companies, where specialist staff matter most, use it actively.

Good data helps a company to:

• avoid overpaying and avoid losing people to better offers;
• make realistic offers to new hires;
• explain pay adjustments to current staff with evidence.

How commercial surveys work

Most surveys are run by HR consulting firms with their own methods and databases. They usually work on a give-to-get basis: you submit your own data and receive the results. The more accurate and detailed your input, the more useful the output.

Typical input includes your grade structure, headcount per grade, base salary, incentive plans and other cash pay. Results show where pay sits in a range, for example low, median and high points. Good reports cover total compensation as well as base salary: bonuses, long-term incentives and equity.

Public data helps too. The Ministry of Employment and Labor (고용노동부) runs the Wage and Job Portal (임금직업포털, www.wagework.go.kr), which publishes wage information by industry, company size and occupation. It is a free reference point for companies that do not buy a survey.

Choosing the right comparison

Pick the peer group carefully. Being in the same industry is not enough. Look at company size, business model, region and growth stage, and choose firms that compete with you for the same people.

Talent markets now cross industries. A traditional financial company hiring IT staff for its digital projects has to look at tech companies' pay as well as other financial firms'.

Match jobs by content. The same title can hide different duties and responsibilities in different companies. Compare the role actually performed and the skills it needs. Consulting firms use standard job classification systems for this.

Fast-moving roles and long-term incentives

In fast-growing fields such as e-commerce, fintech and artificial intelligence, pay moves quickly. Software engineers, data scientists and AI specialists are in short supply, and one start-up's bold offer can ripple through the market. An annual survey can lag behind, so check these roles every quarter or half-year, or benchmark key roles whenever you hire.

Long-term incentives such as stock options and restricted stock units (RSUs) carry real weight in these roles, and start-ups often use equity to make up for lower cash pay. Value them as part of the package. Korean tax rules to keep in mind:

• Gains from exercising stock options while employed are employment income; options exercised after leaving produce other income.
• For venture companies, gains from options granted by December 31, 2027 are tax-free up to ₩200 million a year, with a ₩500 million limit per company, if the legal requirements are met.
• If staff of a Korean company, or of a foreign company's Korean branch, exercise stock options or receive stock-based pay from a foreign controlling parent, the company must file a statement of those transactions (주식매수선택권등 거래명세서) by March 10 of the following year.

Turning results into a pay strategy

Survey results give little value if they only sit in a file. Use them in three ways:

1. As a reality check. Managers and staff may believe "our pay is low" or "we are competitive", and the data may say otherwise. Look at each level and job, and fix the weakest areas first.
2. As a base for hiring and retention. Pay well below market makes hiring hard and pushes people out; pay well above market raises costs. Find the right level and plan any catch-up in stages.
3. As a base for a pay philosophy. No company can pay at the top of the market for every job. Decide where to compete, for example upper-market pay for critical roles and median pay for others.

Think in terms of total rewards (총보상). Lower base pay can be offset by strong benefits, flexible or remote work, sabbaticals, learning support and career growth, which some candidates value more than cash. Match the strategy to your finances and stage: a start-up may share future value through equity or profit-sharing instead of matching large-company salaries. Whatever the strategy, every pay rate must stay at or above the minimum wage: ₩10,320 an hour in 2026 and ₩10,700 from January 1, 2027. See 2027 minimum wage ₩10,700: notify workers by December 31, 2026.

Keep it current

Benchmarking is a process, not a one-off project. Markets shift, new competitors appear and demand for skills changes. Combine the annual survey with information from recruiting, exit interviews and industry networks so you can react quickly. Use the data with judgement and fit it to your own situation and strategy instead of following the market blindly.

Checklist

• Define a peer group by size, business model, region, stage and competition for talent.
• Map your jobs to the survey's levels by actual duties, not titles.
• Compare base pay and total compensation separately.
• Recheck fast-moving roles every quarter or half-year.
• Write down your pay philosophy: where you lead, match or lag the market.
• Check every pay rate against the 2026 and 2027 minimum wage.
• Value stock options and RSUs, and follow the Korean tax and reporting rules for them.
