Can Foreign Workers Claim Overseas Parents as Dependents in Korea?
You work for a Korean company and send part of your salary to your parents overseas.
When year-end tax settlement approaches, you wonder whether those payments could qualify you for a tax deduction.
Your parents have never lived in Korea. Their income records are issued by another country, and their names do not appear in Korean family registers.
Can you claim them as dependents in Korea?
Yes, potentially—but only if you are a Korean tax resident, use the ordinary income tax calculation, and meet the dependent deduction requirements.
The National Tax Service (NTS) expressly recognizes that qualifying foreign workers may claim parents living in their home country.
However, sending money to your parents does not automatically establish eligibility.

First, Check Your Tax Status and Tax Calculation Method
Before collecting documents, check two important conditions.
1. Are you a Korean tax resident?
A foreign worker who qualifies as a Korean tax resident may claim eligible dependents.
A foreign worker treated as a nonresident generally cannot claim a personal deduction for parents. Nonresidents are generally limited to the basic deduction for themselves.
Tax residency depends on the rules concerning a person's residence and living circumstances, not simply their nationality or visa type.
2. Are you using Korea's 19% flat-tax option?
Eligible foreign workers may choose a special 19% flat income tax rate under the applicable rules.
But this special calculation does not allow the ordinary personal income deductions discussed in this article.
If you elect the flat-tax method, you cannot also claim the KRW 1.5 million dependent deduction under the ordinary calculation.
Ask your payroll department which tax method is being used before preparing an overseas dependent claim.
What Are the Requirements for Claiming a Parent?
Under Article 50 of Korea's Income Tax Act, a qualifying parent may generate a KRW 1.5 million basic income deduction.
Three conditions are central.
Age
A parent must generally be at least 60 years old. Special age exceptions may apply where the dependent meets the statutory disability conditions.
Income
The parent's annual income amount must generally be KRW 1 million or less.
If the parent has only employment income, the alternative threshold is KRW 5 million or less in gross wages.
These figures refer to the relevant Korean tax-law income calculation. They should not be confused with a universal limit on every payment received abroad.
Actual support
The parent must qualify as a dependent whose livelihood you actually support.
The NTS specifically recognizes that parents living in another country may satisfy this condition.
But you need credible evidence of support rather than relying only on the fact that the person is your parent.
Does Living in Another Country Prevent the Deduction?
No.
Consider a hypothetical example.
A Filipino software engineer works in Seoul and regularly sends money to his mother in Manila to help pay for groceries, electricity, and medical expenses.
His mother is over 60 and has limited income.
The engineer may be able to claim her as a dependent if he meets the Korean taxpayer requirements and can substantiate her age, income, family relationship, and actual support.
The important distinction is between living separately and failing to support someone.
The NTS does not automatically reject qualifying parents simply because they live outside Korea.
It asks for evidence demonstrating that the legal requirements are satisfied.
What Documents Does the NTS Expect?
The NTS's January 2026 guidance identifies three main types of evidence for foreign workers claiming overseas family members.
Proof of Family Relationship
Obtain a government-issued document from your home country establishing that the person is your parent.
Depending on the country, this may be a birth certificate, family register, or comparable official record.
Foreign public documents may be authenticated through an apostille or appropriate Korean consular confirmation.
The correct method depends on the country issuing the document.
Ask your payroll department whether a Korean translation or additional certification is needed for the particular document.
Proof of Your Parent's Income
The NTS identifies income documentation issued by the foreign government as relevant evidence.
This may include an official income certificate, tax record, or other suitable government-issued statement.
Be careful with overseas pensions and other foreign income.
A foreign pension payment, rental receipt, or investment payment cannot automatically be classified as qualifying or disqualifying based only on its amount.
The treatment depends on the nature of the income and the applicable Korean tax rules.
If your parent receives these payments, ask a qualified tax professional to assess them before claiming the deduction.
Proof of Actual Support
The NTS expressly identifies living-expense remittance records as an example of evidence.
Keep bank statements or remittance confirmations showing the amounts, dates, sender, and recipient.
If you supported a parent through another arrangement, ask which supporting documents can establish the payments and their purpose.
There is no universal NTS requirement in the published guidance that every taxpayer must make exactly one transfer per month.
A remittance record helps establish actual support, but the number of transfers alone does not decide eligibility.
How Much Tax Can You Save?
The basic deduction is KRW 1.5 million per qualifying parent.
That amount is subtracted from income for tax-calculation purposes.
It is not a KRW 1.5 million refund.
Suppose both parents qualify. The total basic income deduction could be KRW 3 million.
If one parent is aged 70 or older, Article 51 may allow an additional KRW 1 million senior deduction for that parent.
In that example, the combined potential income deduction could be KRW 4 million.
Your actual tax saving depends on your taxable income, applicable rates, other deductions, and tax already withheld.
How Do You Submit the Claim?
For an employee, the normal starting point is the company's year-end tax settlement process.
Step 1 — Confirm eligibility
Ask payroll whether you are treated as a Korean tax resident and whether your tax is calculated using ordinary rates or the special flat-tax option.
Step 2 — Check each parent's details
Record their dates of birth, income sources, and whether another eligible taxpayer is claiming the same person.
Step 3 — Collect overseas evidence
Prepare family relationship records, available official income documents, and remittance records showing actual support.
Step 4 — Confirm authentication requirements
Check whether the foreign documents need an apostille, Korean consular confirmation, or translation.
Step 5 — Submit documents to payroll
Provide the dependent information and supporting documents through your employer's year-end settlement process.
Foreign documents may not appear automatically in Korea's Hometax simplified tax data. Do not assume that missing information in Hometax means the deduction is impossible.
Ask payroll how manually supplied evidence should be submitted.
Common Mistakes to Avoid
Assuming every foreign employee qualifies
Nonresidents and workers using the special flat-tax calculation cannot claim the ordinary overseas-parent deduction in the same way as resident workers using ordinary rates.
Treating every overseas pension as taxable income
The correct treatment requires examination of the payment and applicable rules.
Confusing financial gifts with actual support
Occasional transfers do not automatically prove that a parent qualifies as a dependent.
Claiming the same parent twice
The same qualifying dependent cannot generate duplicate basic deductions for multiple taxpayers.
Mistaking an income deduction for a cash refund
A KRW 1.5 million deduction reduces the tax calculation base; it does not guarantee a KRW 1.5 million payment.

Before You Meet a Tax Specialist
Bring your employment income information, the tax calculation method used by your employer, and the following documents:
Your parents' dates of birth and family relationship records.
Official information about their income and pensions.
Remittance statements or other evidence of financial support.
Any foreign-document authentication already obtained.
Ask these questions:
Am I a Korean tax resident for the relevant year?
Am I using ordinary income tax rates or the foreign-worker flat-tax option?
How should my parent's overseas pension or other income be treated?
What evidence establishes actual support in my situation?
What documents must I give my employer, and in what format?
For questions about foreign-worker year-end settlement, the NTS also provides an English-language consultation line at 1588-0560.
The Key Point
A foreign worker who is a Korean tax resident may claim qualifying parents living overseas—but not merely because money was sent home.
Eligibility depends on the taxpayer's tax calculation method, the parent's age and income, and evidence of actual financial support.
The most practical approach is to confirm your tax status first, then collect official family and income records alongside your remittance history.
