Medical Expense Tax Credit in Korea for Foreign Workers
Year-End Settlement
Who this guide is for
- Foreign employees with Korean medical costs
- Workers supporting eligible family members
- Employees with missing Hometax medical data
- People comparing progressive tax with the flat tax
Quick Answer
Foreign employees using Korea's normal progressive tax calculation may claim eligible medical expenses through year-end settlement when the statutory conditions are met. The credit calculation can depend on total salary, the patient, expense type, reimbursements, and supporting evidence; the foreign-worker flat tax generally does not combine with ordinary deductions and credits.
Key points
- Eligibility depends on who received and who paid for treatment.
- A salary-based threshold can affect the credit.
- Reimbursed amounts should not be double counted.
- Some treatments and wellness purchases are excluded.
- Missing simplified-service data may be supported separately.
Detailed explanation
Check the tax method first
Ordinary income deductions and credits are generally relevant when the employee uses progressive taxation. A worker choosing the special foreign-worker flat tax should compare the full result because that method normally replaces ordinary deductions and credits.
Match the patient and payment
Create a list showing the patient, relationship, provider, amount paid, reimbursement, and whether the item appears in the simplified service. Rules can differ for the employee, older or disabled family members, and other eligible dependents.
Reconcile Hometax with receipts
Simplified-service data is a starting point, not proof that every displayed item is claimable or that every eligible item is displayed. Obtain receipts for missing eligible expenses and remove reimbursements or excluded items.
Preserve the calculation
Keep the employer submission, receipts, reimbursement evidence, and a short worksheet explaining the amount claimed. This helps if the employer requests clarification or the deduction is reviewed later.
