Overview

AI-generated overview

Calculates South Korea 2026 payroll and tax figures — net pay, social insurance, severance, leave, and jobless or parental benefits.

What you can do
  • Compute take-home pay and withheld income tax plus local income tax for a monthly wage
  • Break down the four major social insurances, with employee deductions and employer contributions
  • Calculate statutory severance pay and the retirement income tax on it, including the IRP pension reduction
  • Work out paid annual leave days, remaining days, next accrual and payout value of unused leave
  • Estimate unemployment benefit amounts and days, and month-by-month parental leave benefit including the 6+6 scheme
When to use it
Useful for HR, payroll and finance work involving Korean employees, or for quickly checking what a given monthly wage, hire date or leave balance means under 2026 Korean rules.
Requirements
Remote MCP endpoint at api.kkuldogu.com over streamable HTTP; no packages, environment variables or headers are declared, and no authentication is declared.
Before you install
Results are calculations based on 2026 rates and a simplified withholding table, so they are estimates rather than official payroll or tax advice; verify against NTS and insurance guidance before using them for real payments or filings. Wage, hire date and pay history you submit go to a third-party server.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.dooolmang%2Fkkuldogu-korea-payroll/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.
