Quick answer: Service members in Korea are paid in US dollars, so what your pay buys off the installation depends on the won exchange rate, and every conversion costs a spread or a fee. Use the calculator below to compare an on-base exchange, an ATM withdrawal and a card payment against the mid-market USD/KRW rate. Korea is not on the IRS list of combat zones, so the combat zone pay exclusion does not apply to duty in Korea.

This USFK money guide is for US service members, DoD civilians and family members stationed anywhere in Korea. It covers the everyday question of how to turn dollars into won without losing money on every swap, plus the tax and reporting points that trip people up: SOFA status, the combat zone myth, allowances and the FBAR.
We do not quote bank or exchange counter prices, because they change daily. Enter the rates and fees you actually see, and the calculator ranks them against the reference rate.
Loading the current USD/KRW reference rate.
Military OneSource puts it simply: you are paid in dollars, what a dollar buys depends on the local exchange rate, and you should expect a small fee whenever you convert cash dollars into local currency. That fee shows up in three forms:
If a terminal or ATM offers to charge you in dollars instead of won, that conversion is done at the machine's rate. Choose won and let your own card do the conversion, then check the result with the calculator.
| Option | Good for | Watch for |
|---|---|---|
| On-installation banking center | Cash won before going off post, converting won back before PCS | Posted buy and sell rates and buy-back limits |
| ATM off post | Cash when you need it | Operator fee, your bank's foreign ATM fee, the rate applied |
| US card in Korean shops | Larger purchases, travel | Foreign transaction fee; pay in won, not dollars |
| Korean bank account | Off-post rent, utilities, local transfers | Account opening rules; see our account guide |
Community Bank, which lists banking centers in Korea, tells customers that actual exchange rates at the banking center and ATM can differ from its online calculator and to check locally for currency buy-back rates and limits. Ask before you convert a large amount.
Overseas COLA and OHA move with the won. Military OneSource warns that OCOLA can change from paycheck to paycheck with the exchange rate and should not be treated as a fixed part of your monthly budget. Military OneSource points to the official OCOLA and OHA calculators to see current rates and the pay system exchange rate. For federal income tax, IRS Publication 3 lists housing and cost-of-living allowances abroad paid by the US government, including OHA, as excluded from gross income.
SOFA status covers members of the US armed forces, the civilian component and their dependents. Article XIV, paragraph 2 of the US-ROK SOFA, as quoted by Army MWR at Camp Humphreys, says these persons, in Korea solely for that reason, "shall not be liable to pay any Korean taxes" on "income derived from sources outside of the Republic of Korea". The same Army MWR notice says remote work by SOFA dependents for US employers is permissible and normally nontaxable under the SOFA. Income from Korean sources, such as a local job, is outside that sentence, so talk to your installation legal office before taking Korean employment.
| Topic | What applies in Korea |
|---|---|
| Combat zone exclusion | Not available for Korea; it is not on the Pub. 3 list |
| Foreign earned income exclusion | Not available to military or civilian US government employees, including exchange workers; a spouse can use it only as an independent contractor who is not a US government employee |
| OHA and overseas COLA | Excluded from gross income |
| Filing deadline | Automatic 2-month extension if your post of duty is outside the US and Puerto Rico |
| FBAR | Required if your foreign accounts together exceed $10,000 at any time in the year; due April 15 with an automatic extension to October 15 |
A Korean bank account opened off post counts toward the FBAR threshold; an account at an institution located on the installation does not. Check your position with our FBAR and FATCA threshold checker.
Because your pay already arrives in dollars, the cheapest transfer is often no transfer: keep dollars in your US account and convert only what you spend in won. Money earned in won, for example by a spouse with a local job, needs a real remittance; compare options with our transfer calculator and cheapest way to send money from Korea guide.

No. IRS Publication 3 for 2025 returns lists the Afghanistan area, the Kosovo area and the Arabian Peninsula as combat zones and the Sinai Peninsula as a qualified hazardous duty area. Korea is not on the list, so the combat zone pay exclusion does not apply to duty in Korea.
No. FinCEN instructions say an account at a financial institution located on a US military installation is not required to be reported, even if the installation is outside the United States. A Korean bank account off post does count toward the $10,000 threshold.
No. IRS Publication 3 says military and civilian employees of the US government, including exchange employees, cannot elect it. A spouse may qualify only as an independent contractor who is not a US government employee and meets the normal tests.
Army MWR at Camp Humphreys says remote work by SOFA dependents for US employers is normally nontaxable under SOFA Article XIV, which covers income from sources outside Korea. Confirm your case with the installation legal office.
Overseas COLA follows the exchange rate. Military OneSource says it can change from paycheck to paycheck with currency moves, so it should not be treated as a fixed part of your budget.
It depends on the rates and fees you face. Compare the on-base exchange spread, ATM fees plus spread, and your card foreign transaction fee with the calculator, and always choose to be charged in won.
