You still own the officetel in Seoul. A tenant pays rent into your Shinhan account every month, and none of it ever touches a US bank. Once you’re a US tax resident — green card holder, someone who passes the Substantial Presence Test, or a citizen — that Korean rental income belongs on your US tax return anyway. Worldwide income rules don’t care where the property sits.
Most people who miss this aren’t hiding anything. They assume a foreign rental only matters once money crosses the Pacific. It doesn’t work that way. The mechanics of reporting it — currency conversion, depreciation, and credit for tax already paid in Korea — trip up people who file correctly every other year.
Reporting Korean Rental Income on Schedule E
A rental property in Korea gets reported the same way a US rental would: on Schedule E, attached to your Form 1040. You list gross rent received, then subtract allowable expenses. The result is net rental income or loss. Location doesn’t change the form.
Expenses that reduce your reportable Korean rental income typically include:
- Korean property tax (재산세) paid on the unit
- Management or building maintenance fees
- Repairs and routine upkeep
- Mortgage interest, if the property carries a Korean loan
- Depreciation, calculated separately below
Check the IRS’s Schedule E instructions for the full list of allowable categories. Not every Korean expense maps cleanly onto a US line item.
Takeaway: Korean rental income goes on Schedule E exactly like a domestic rental, with the same categories of deductible expenses.
Currency Conversion for Korean Rental Income
Won-denominated rent has to become dollar figures somewhere on the return. The method matters. A common simplified approach converts all Korean rental income and related expenses for the year using the IRS’s annual average exchange rate, applied once to the full year’s totals.
The alternative is converting each transaction at the rate on the date it happened. That’s more precise but far more work for a single rental unit. Consistency matters more than which method you pick. Use the same approach for income and expenses in a given year, and don’t switch methods without a reason.
Here’s a worked example. Annual rent totaled 24,000,000 KRW. Monthly management fees paid by the tenant added another 3,600,000 KRW for the year, which counts as additional gross rent before expenses. The average rate that year was 1,320 KRW to the dollar. Reported gross rental income would land around $20,909 for the year, before subtracting property tax, management costs, and depreciation.
Takeaway: Convert Korean rental income using a consistent method — average annual rate is simplest — rather than mixing rates on one return.
Depreciation Rules for a Rental Property in Korea
US rental property is normally depreciated over 27.5 years. A foreign residential rental, including a unit in Korea, follows a different and longer recovery period under the rules for foreign real property. The annual depreciation deduction ends up smaller than it would for an identical US property.
A few points catch people off guard:
- The depreciable basis is the property’s cost basis converted to dollars, not its current market value
- Land value still isn’t depreciable, same as with a US rental
- A longer recovery period shelters less of your Korean rental income each year, compared to a similarly priced US rental
Find a preparer who has actually handled foreign rental property before. The recovery period differs enough from domestic rules that a generalist can easily apply the wrong schedule. Ask specifically whether they’ve filed Schedule E for a foreign property before, not just a domestic rental — the two use different depreciation tables entirely.
Takeaway: A Korean rental property depreciates over a longer period than a US property, which shrinks the annual deduction against that income.
Foreign Tax Credit on Korean Rental Income
Korea taxes rental income earned within its borders. The same income can get taxed twice — once by Korea, once by the US — without something to offset it. The Foreign Tax Credit exists for exactly this. Tax you’ve already paid to Korea on that rental income can generally offset US tax owed on the same income, dollar for dollar up to certain limits.
Claiming the credit requires documenting what was actually paid to Korean tax authorities, converted to dollars using a consistent method. Keep the Korean tax receipt or withholding statement, since the IRS may ask for it if the credit gets reviewed. Skip the credit, and the same rental income effectively gets taxed at both countries’ rates combined. That’s rarely the correct outcome under the US-Korea tax treaty framework.
Takeaway: The Foreign Tax Credit prevents Korean rental income from being taxed twice, but only if you claim it and document the Korean tax paid.
FBAR and FATCA on the Account Collecting the Rent
The rent itself lands somewhere — usually a Korean bank account in your name. That account raises a separate reporting question from the Schedule E filing. Once the aggregate value of your Korean accounts crosses $10,000 at any point in the year, FBAR applies. Higher FATCA thresholds can apply too, depending on your filing status and total foreign assets.
This catches people who correctly report Korean rental income on Schedule E but never realize the account holding that rent triggers its own filing. It’s easy to assume the Schedule E filing is the whole story, especially when a tax preparer only asks about the rental and not the bank account behind it. Our FBAR vs FATCA breakdown covers the full set of thresholds, forms, and penalties. The rules differ meaningfully from the income tax side.
Takeaway: Reporting rental income on Schedule E doesn’t cover FBAR or FATCA — the account collecting that rent needs its own separate check.
FAQ
Do I have to report Korean rental income if the money stays in Korea?
Yes. US tax residents report worldwide income regardless of where it’s earned or held. Korean rental income counts even if the rent never leaves the Korean bank account it’s deposited into.
What exchange rate should I use to convert the rent?
The IRS’s annual average exchange rate is a commonly used, simplified method for converting a full year of Korean rental income and expenses. Whichever method you choose, apply it consistently across the return.
Can I deduct Korean property tax and management fees?
Generally, yes. Korean property tax, management fees, repairs, and mortgage interest on the property typically reduce reportable rental income on Schedule E, similar to a US rental property. Keep receipts and statements in Korean; you can translate the key figures for your own records rather than the whole document.
Do I need to file FBAR for the Korean account that collects rent?
If the account, combined with any other Korean accounts, exceeded $10,000 at any point during the year, yes. That’s separate from reporting the rental income itself, with its own deadlines and penalties. A modest rental deposit plus a few months of accumulated rent can cross that threshold faster than people expect.
Quick Summary
- Korean rental income is reportable on Schedule E for any US tax resident, even if the rent never leaves Korea
- Convert income and expenses using a consistent exchange rate method, such as the IRS annual average
- Foreign rental property depreciates over a longer recovery period than a US property
- The Foreign Tax Credit offsets Korean tax already paid, and FBAR/FATCA apply separately to the account holding the rent
