Year-end tax settlement for foreigners, increasing refunds with 12 months of spending

If you miss this one line, you will have to pay additional tax.

Key Summary

• The criteria are expenditures from 1/1 to 12/31 and family/contract information.

• The company recalculates last year's taxes once a year (Jan-Feb).

• Even if missed, it can be supplemented within 5 years through a corrected return.

Terms Explained in One Line

• Year-end tax settlement: The process where the company recalculates last year's taxes in January-February.

• Deduction: An amount subtracted from taxable income.

• Tax credit: An amount directly subtracted from the calculated tax.

• Corrected return: A request to recalculate, made within 5 years after filing.

• Simplified data: A collection of receipts for medical, education, donations, and card expenses compiled by Hometax.

30-Second Check

• Are your card and cash receipts used consistently throughout the year?

• Can you gather your lease agreement and transfer records with matching names?

• Do you have dependents (spouse, children, parents) eligible for deductions?

• Have you secured receipts for medical expenses, education expenses, and donations?
  👉 If yes to 3 or more items, the possibility of a refund is high.

Points That Change

• Differences in documentation can lead to refunds varying by tens of thousands to hundreds of thousands of won.

• The settlement is once a year. Recording now will finish it in one go.

• If classifications or documents are mismatched, you may face additional payments or require document correction.

Case Comparison

• Applicability: Case A: Documents/Names Match vs Case B: Missing Documents/Name Mismatch

• Key Difference: If proof is missing, the corresponding deduction is treated as 0 won.

• Actual Impact: A difference of tens of thousands to hundreds of thousands of won in the refund amount.

What to Do Now

1. Prepare for Hometax simple authentication/joint certificate.

2. Gather card, cash, medical, education, donation, and rent receipts into one folder.

3. Check your most recent payslip for markings in the non-taxable and deduction sections.

4. Obtain the latest version of your Family Relations Certificate/Resident Registration Copy.

5. If renting, verify the lease agreement and bank transfer records match.

Practical Examples

• Case A: Single-person household, significant card spending, no rent → Refund of tens of thousands of won.

• Case B: Spouse + 1 child, rent of 600,000 won per month, medical expenses incurred → Refund of hundreds of thousands of won.

Confusing Points

• "Foreigners are not subject to year-end tax settlement" → If you have earned income, proceed through your company.

• "Year-end tax settlement always results in a refund" → You could potentially pay additional tax.

• "If it appears in simplified data, it's done" → You need to personally check for missing items or name mismatches.
