Year-End Settlement for Foreign Employees

There is no separate foreign tax system and no foreign deduction table.

A foreign employee receiving Korean employment income goes through the same January settlement as everyone else: the company compares what it withheld monthly against the year’s actual liability, and collects or refunds the difference.

The differences that do exist come from four places — residence status, family living abroad, housing conditions, and whether the 19% flat rate was elected. Not from nationality.

Sort the method first. The paperwork follows from it.

The calendar is the same

The National Tax Service runs the foreign employee settlement on the same schedule and the same procedure as everyone else’s.

Where the company uses the bulk provision service, it registers its employee list with the tax office and the employee consents in Hometax to the scope of data being handed over. In the most recent cycle that consent window ran from early December to mid-January, with the company collecting the simplified data afterwards.

Not every foreign employee files the same documents

A common overstatement is that a foreign employee must submit proof of alien registration every year.

The guidance asks for it from newly hired foreign employees and those whose dependants have changed — not as a universal annual requirement.

Residence is the first fork, and it is a big one

A foreign employee who is a tax resident can, in principle, access the same structure a Korean employee does — the basic deduction, credit card usage, medical, insurance, education and donation credits, the child credit.

A non-resident cannot. The comparison is stark:

So the first question in a foreign employee’s settlement is not “are they foreign”. It is “were they a Korean tax resident for that tax period” — and that is a question about their life, answered in income tax for foreigners: resident or not.

The housing rule changed in 2021, and the old sentence is still circulating

This is the most consequential correction in the whole guide.

Older material explains that foreign nationals cannot claim housing deductions because they cannot be a head of household under the resident registration system. That stopped being the position in 2021.

A qualifying foreign resident may claim:

The rent credit turns on your registered stay address

For a foreign resident the monthly rent tax credit runs on a condition Korean employees never meet, because it does not apply to them.

What matters is not the address on a resident registration extract. It is your registered place of stay under the Immigration Act — and the decree requires the address on the lease and the registered place of stay to match.

where you actually live
  = the address on the lease
  = your reported place of stay with immigration

Which ties this deduction directly to something else with its own deadline: report a change of stay address within 15 days of moving, or these three fall out of alignment. That obligation is in keeping D-4 status, and it applies well beyond students.

Transferring the rent by bank transfer is not by itself enough — total salary, not owning a home, the property’s value and size, and whose name is on the contract all have to be satisfied too.

Housing subscription savings: still restricted, but no longer closed

Keep this one separate from the deductions above.

Because a foreign national cannot be a head of household in the ordinary sense, claiming housing subscription savings as a non-home-owning head of household is generally not available.

From contributions made in 2025, an exception opened. A foreign employee who is a Korean resident, has total salary of ₩70,000,000 or below, is the spouse of a head of household owning no home, and contributes to a qualifying housing savings account in their own name, may deduct 40% of contributions up to ₩3,000,000 a year.

So the accurate statement is neither “foreigners can” nor “foreigners cannot”:

Tracked at the housing savings exception.

Family abroad can be claimed. Money spent abroad usually cannot

These two get confused constantly, and they point in opposite directions.

Dependants living abroad — yes

A spouse in your home country can qualify for the basic deduction where the income test and the rest are met. There is no requirement that dependants live in Korea.

For parents or children abroad, you additionally have to show actual support — the guidance gives remittances of living expenses as the example.

Documents issued by a foreign government need an apostille where that country is party to the convention, or consular confirmation at the Korean mission where it is not.

relationship  +  age and other conditions  +  income  +  actual support

Build that as one file, not four separate scrambles in January.

Money spent abroad — generally no

None of these are cases of Hometax failing to collect something. They are outside the deduction, and the distinction matters:

Electing 19% changes what the paperwork is for

Elect the flat rate and the exemptions, deductions, reductions and credits are in principle not applied to that employment income. So medical, education, card and rent documents make no difference to the calculation, however many are submitted.

What you submit instead is the foreign employee flat-rate application, attached to your deduction and credit return and given to the employer as withholding agent — or to the district tax office if you are electing on an annual return.

Which method actually costs less, and why the crossover is much higher than usually quoted, is in the 19% flat rate: when it beats the brackets.

The order HR should work in

Not receipts first.

Working this way stops the commonest error, which is claiming something on the strength of a receipt for a payment that was never deductible.

The simplified service is not an approval

Its value is that it collects from hospitals, card companies, insurers and financial institutions automatically. It does not confirm that a deduction’s legal conditions are met.

A dependant’s medical expenses can appear without that person qualifying as a dependant. Housing data can appear without the ownership, income, address and loan conditions being satisfied. The employee still has to check.

The reverse holds too: a legitimate item missing from the simplified data can be claimed by obtaining the receipt or payment certificate from the institution and submitting it to the company. The guidance says so explicitly for insurance, medical, education, donation and card-related items.

January is not the last chance

Missing a deduction in the January settlement does not extinguish it. It can be picked up in the following May filing period, or through a claim for correction where the conditions are met.

The asymmetry is worth internalising: claiming something you were not entitled to can mean additional tax later, with penalties attached.

Which is why the objective for a foreign employee is not maximising the refund. It is being able to evidence every deduction claimed — and the evidence for dependants abroad in particular takes weeks to assemble from another country.

The whole thing, in order

tax residence
  → progressive or 19%
  → dependant eligibility
  → housing conditions
  → qualifying Korean expenditure
  → simplified data
  → missing evidence
  → company settlement

The largest single risk is not missing a receipt. It is using guidance written before 2021, concluding that a foreign employee cannot claim housing, and quietly giving up deductions that have been available for years.

Nationality is not what makes a foreign settlement different. What makes it different is whether residence, household, registered stay address, actual spending and the elected method all line up with each other.
