Your First Salary: How a Korean Pay Slip Works, and How to Read One Elsewhere

Gross is not the amount that arrives

A first salary often surprises people because the contracted monthly figure is gross. Tax withholding and social-insurance contributions come out before the deposit. The Korean original walks a new worker through that gap. Readers outside Korea can use the same habit: read every line on the slip, then look up the official name of that deduction in their own system.

Those change by year, by income band, and sometimes by workplace size.

How a Korean slip is usually built

A typical Korean wage slip shows basic pay and any allowances, then withholding income tax and local income tax, then the worker's share of social-insurance contributions. The four social insurances, as official categories, are national pension, national health insurance (with long-term care as officially linked), employment insurance, and industrial-accident compensation insurance. The employer's share is often listed separately or only in a workplace notice.

National Tax Service and National Health Insurance Service or National Pension Service pages, and the slip itself, are the places to confirm the current worker share. A blog's remembered 'around X percent' is not a source.

How to map the same idea in another country

In the United States, a first W-2 job usually withholds federal income tax, Social Security, and Medicare, and often state tax; health insurance, if deducted, is a plan matter, not NHIS. In Japan, 所得税 withholding, 住民税 (on its own calendar), 厚生年金 or 国民年金, and 健康保険料 or 国民健康保険 appear under official names that should be read on the 給与明細 and on 国税庁 or 日本年金機構 pages. In China, individual income tax withholding and social-insurance plus housing-fund categories are set locally; use the official local bureau and the slip. In several Gulf states, a first package may have few or no income-tax lines and different end-of-service or social-insurance rules for nationals and for expatriates; read the contract and the official labor or tax page, not an assumption copied from Korea.

The comparison is a map of categories, not a claim that the burden is the same.

What to do with the first deposit

Write down the gross, each deduction, and the net. Ask payroll to explain any line you cannot name. Set aside money for a later tax settlement if your system has one. The Korean original also talks about first-month spending; the useful rule is to budget from the net, not from the contract headline.

FAQ

Why is net pay lower than the contract wage?
Because tax and social-insurance contributions are withheld or shared, as the law and the contract state. The exact amounts belong on the slip and on official rate tables for that year.
What are Korea's four social insurances, as categories?
National pension, national health insurance (with long-term care as officially linked), employment insurance, and industrial-accident compensation insurance. Contribution shares and rates change; quote a current official table, not a campus memory.
Is this tax advice?
No. It is a reading guide for a first slip. Questions about your own return belong with a tax office, a licensed adviser, or the employer's payroll contact.
