Hiring a business interpreter in Korea is a procurement decision with published prices, defined team sizes, and, once a dispute or a deed is involved, a statutory role. University interpreting centres list day rates by language and duration, simultaneous work takes two interpreters, and your commercial meetings sit outside all of it. Brief the interpreter properly and they carry your position. Skip that and they carry an approximation of it.
The room the interpreter works in is described in the wider guide to Korean business culture and how deals get done. This piece covers the instrument itself: where interpreters come from, what a quote contains, how to brief one, and the settings where Korean law decides who interprets.
Who Actually Interprets for Business in Korea?
Two populations do this work. Conference interpreters come out of Korea’s interpreting graduate schools and are priced by the day; bilingual staff, agency generalists and partner employees fill everything below that. Decide which one you are buying. Your own bilingual employee suits exploratory meetings and technical working sessions, where continuity and product knowledge outweigh linguistic precision. Buy a professional once numbers, terms, exclusivity or termination are on the table, once several people speak at once, or once the record may matter later.
Ewha Womans University’s Graduate School of Translation and Interpretation runs Korean-English, Korean-French, Korean-Chinese and Korean-Japanese interpreting majors. At Hankuk University of Foreign Studies, the conference interpreting major requires passing both the consecutive and the simultaneous paper. Ask which major, and ask for the language direction.
Korea’s only statutory interpreting qualification is the tourist guide interpreter licence, which Article 38 of the Tourism Promotion Act requires travel agencies serving foreign tourists to use, with a fine of up to 5 million won under Article 86(1) for guiding without it. Conference and business interpreting carries no equivalent, so a qualification claim resolves to a school, an association, or a client list you can check.
How Do You Source and Vet a Business Interpreter in Korea?
Four channels supply the market. The university interpreting centres take direct enquiries: the Ewha Center for Interpretation and Translation and the HUFS Center for Interpreting and Translation both assign from their own graduate pools and publish price lists. Ewha’s centre supplies English, Japanese, Chinese and French directly; expect a longer lead time outside those four. Agencies sit above the freelance market and add coordination. Direct freelance hire runs through the AIIC directory, searchable by city and by the A, B and C classification that tells you which direction an interpreter works into. For anything within reach of a contract or a deed, the fourth route is to have your Korean counsel supply or approve the interpreter, because the Notary Public Act puts that choice on the party requesting the deed.
Vet on four questions. Which school and which major, so you know whether simultaneous is in scope. Which sectors they have worked in, because semiconductor process, pharmaceutical regulatory and financial vocabulary are separate competences. Whether they have worked for your counterpart. And whether they will sign your confidentiality agreement. Article 2 of AIIC’s 2022 Code of Professional Ethics binds members to the strictest secrecy at any gathering not open to the public, and the obligation you can enforce is the one you put in writing, so name the meeting, the materials and the retention period.
Consecutive or Simultaneous, and What Does Each Cost You?
Consecutive suits negotiation, simultaneous suits presentation, and the difference shows up in your agenda before your invoice. Consecutive means the speaker and the interpreter alternate, so budget close to double the speaking time. Simultaneous runs in real time from a booth, at the cost of a second interpreter and equipment.
Team size follows published practice. AIIC’s professional standards bar an interpreter from working alone in a simultaneous booth as a general rule. Both Korean university centres publish a two-person simultaneous team as the minimum, and Ewha’s centre adds a third at eight hours or high difficulty. Ewha puts consecutive at one interpreter and says a second may also be required for meetings of four hours or more or of high difficulty, so treat four hours as the point where team size becomes a question to settle in the quote.
Equipment is a separate purchase from a separate supplier. The interpreting centre supplies people, while the booth, console, transmitter, receivers and on-site technician come from the venue or an AV rental vendor. Large Korean venues attach booths to their bigger rooms: COEX lists a simultaneous interpretation booth among the facilities of its third-floor conference rooms from 207 square metres, with room 308 expressly excepted, and two booths in the 489 square metre Grand Conference Room 401 on the fourth floor, on venue pages read in September 2026. Specify the booth when you book the room. A function room without one usually means a mobile booth brought in, and ISO 4043:2016 is the specification to hand the vendor. For a small audience and a short session there is a cheaper answer: HUFS prices guide-equipment simultaneous without a booth, for an audience of three or more, at 150 percent of the interpreting fee, with one interpreter up to two hours and two beyond that.
What Does a Korean Interpreter Day Rate Actually Cover?
It covers one interpreter, in Seoul, for a defined number of hours, and very little else. Two Korean university centres publish checkable tables.
The Ewha Center for Interpretation and Translation lists English at 1,000,000 won per interpreter per day for up to six hours in Seoul, with 200,000 won per hour beyond that, applying since 1 December 2023. The HUFS centre grades by experience, read as of September 2026: English, German and French at 900,000 won up to six hours under two years out and 1,000,000 won at two years or more, VAT excluded. Both are per interpreter, so simultaneous doubles it.
Ask for the short-duration tier by name. The day rate is the default when nobody asks for anything else, and both tables carry shorter units: HUFS publishes a one-hour rate for each language it covers, 600,000 won for an English interpreter under two years out and 700,000 won at two years or more, and Ewha lists French at 600,000 won up to two hours. A ninety-minute meeting bought as a full day is the easiest overspend in this line item, and agency and freelance quotes move around these tables.
Outside the day rate, quotes diverge. Both centres charge cancellation on the same scale once the interpreter is booked: 30 percent of the base fee at four to seven days out, 40 percent at two to three days, 50 percent the day before, and 100 percent on the day. Both charge for a separate-day pre-meeting, Ewha at a full day rate and HUFS at 200,000 won per interpreter per hour. Recording needs the interpreter’s prior consent and costs 50 to 100 percent more at Ewha. Night hours and out-of-Seoul travel carry their own lines.
A two-day Seoul negotiation at the Ewha English table assembles like this. Six-hour days sit past Ewha’s four-hour mark, where a second interpreter may be required, and the rate is per interpreter per day, so two interpreters across two days is 4,000,000 won. A separate-day pre-meeting at 100 percent of the base day rate adds 1,000,000 won, for a Seoul total of 5,000,000 won. Hold each meeting to four hours and one interpreter covers it, which brings the same trip to 3,000,000 won. That four-hour mark is the line to design the agenda around. Ewha’s rate, service and enquiry pages carry no VAT line, so confirm on the quote whether the 1,000,000 won is gross or net. Outside Seoul the HUFS table adds travel: two days at its senior English rate is 2,000,000 won, travel-time compensation for the day before is 400,000 won, and the 200,000 won daily allowance across two meeting days is 400,000 won, giving 2,800,000 won plus VAT, which HUFS publishes as excluded, plus transport and a hotel room. That leg prices one interpreter, because the four-hour rule is Ewha’s and HUFS publishes no consecutive team size on its rate or service pages.
A centre or agency bills as a registered business, so expect VAT at 10 percent under Article 30 of the Value-Added Tax Act and a tax invoice under Article 32(1). Paying a Korean individual freelancer moves the mechanics to withholding at source, and two questions decide what that means for you.
The first is whether you are the withholding agent at all. Article 127(1) of the Income Tax Act attaches the duty to a person paying the listed income 국내에서, in Korea, and Article 184(3) of its Enforcement Decree limits the payer for withholdable business income to businesses, corporate taxpayers, the State and local governments, and bodies treated as legal persons. A foreign company with no Korean entity, settling a Seoul freelancer’s invoice from abroad, sits outside that: it holds no Korean business registration number to file a withholding return against, and it cannot remit. The mechanism runs through your Korean subsidiary, your Korean counsel, or an agent acting as the payer. Pay directly from overseas and you settle the gross invoice, and the interpreter declares the income themselves.
The second is which kind of income the fee is, and that turns on the interpreter’s own trade. Interpreting supplied as a continuing business is business income, which Article 19(1)21 of the Income Tax Act describes as activity carried on continuously and repeatedly for profit, and Article 129(1)3 withholds 3 percent on withholdable business income. Article 184(1) of the Enforcement Decree defines that category as the personal services Article 26(1)15 of the Value-Added Tax Act exempts from VAT, and Article 42(1) of that Act’s Enforcement Decree lists translation, with similar services, supplied by an individual holding no premises and employing nobody, without listing interpreting by name. With local income tax at 10 percent of the income tax under Article 103-13(1) of the Local Tax Act, that is the 3.3 percent Korean freelancers quote, and the interpreter’s own filing is what puts a fee inside it. Personal services supplied on a one-off basis by someone whose living is not interpreting are other income under Article 21(1)19, withheld at 20 percent under Article 129(1)6(d), and Article 87, subparagraph 1-2 of the Enforcement Decree treats 60 percent of the payment as expenses, which makes it 8 percent plus local income tax, so 8.8 percent. A conference interpreting graduate working through a centre or running a freelance practice is the first case, and the bilingual specialist you engage once for a single meeting can be the second. Ask which the interpreter files as before you agree any net figure.
How Do You Brief an Interpreter and Build the Glossary?
Send the materials in advance and pay for a pre-meeting. AIIC’s code of professional ethics requires members to ask for working documents in advance and to request a briefing session where appropriate, and Korean courts run the same discipline. The Supreme Court’s guideline on interpreting, translation and the handling of foreign-national cases (통역ㆍ번역 및 외국인 사건 처리 예규, 재일 2024-1), amended on 26 August 2026 and in force from 7 September 2026, requires the participating clerk at Article 4 to forward filed pleadings and party and witness examination questions to the interpreter so the interpreting can be prepared in advance. Build a bilingual glossary short enough to be used: product and process terms with the Korean rendering you want, expanded acronyms, the counterpart’s organisation with each title in Korean, as set out in the guide to Korean company hierarchy, and any term you refuse to have paraphrased. Korean groups large figures in units of ten thousand and one hundred million, so repeat every commercial figure in digits.
Then brief the person. Say what the meeting is for, which of your sentences are positions and which are exploration, and what you plan to leave unanswered. An interpreter who knows which sentences are positions renders them at full strength and flags the ones that landed badly, instead of smoothing all of them equally.
Half the performance is yours. Speak in short complete units and pause at clause boundaries instead of mid-sentence. Drop idiom, sports metaphor and wordplay, which consume the interpreter’s time and produce nothing. And never ask a negative question: a Korean yes to “You do not need the samples?” confirms the negative, and the English rendering will invert it.
How Do Honorifics and Hierarchy Change What an Interpreter Can Say?
Korean encodes relative status in verb endings and forms of address, so every sentence rendered into Korean makes a status choice on your behalf, and by default your interpreter makes the safe one. Manage that default directly. Tell the interpreter where you sit relative to each person in the room, and that a refusal is to be delivered as a refusal. Experienced interpreters soften hard messages to protect the room, so ask for your position at full strength with a flagged aside if it landed badly. How indirect Korean answers are read is covered in the guide to nunchi in business, and what silence and pace mean sits in the guide to negotiating with Korean companies.
Agree that the interpreter never answers on your behalf, and that they interpret side conversations they overhear. And do not accept the counterpart’s employee as the interpreter for both sides, a point the guide to Korean business etiquette makes about junior staff and which holds at any rank: the person rendering your position should not report to the company across the table.
Where Does Korean Law Decide Who Interprets?
None of this reaches the meeting you are buying an interpreter for. A commercial negotiation, a factory audit or a trade-show meeting is unregulated: you choose, and the only rules are the ones in your contract. The provisions below start once you are in a courtroom, in front of a notary, under immigration questioning, or in an arbitration whose language was never agreed.
Korean law decides in four settings. Courts and immigration officers appoint without reference to you. In notarisation and arbitration the choice is yours, and both are settled before the day arrives.
Courts come first. Article 62 of the Court Organization Act makes Korean the language of the courtroom and requires interpretation where a party does not command it. Article 180 of the Criminal Procedure Act and Article 143(1) of the Civil Procedure Act require an interpreter for statements and oral argument. The same Supreme Court guideline runs the appointment: Article 16(1) has each court compile a candidate list of two or more interpreters per language by the end of January, Article 17(1) vets those candidates through documentary review, an interview and a criminal record check, and Article 20(1) has the clerk select from that list for the case. Article 25, subparagraph 1 fixes the fee at 70,000 won for the first thirty minutes and 50,000 won for each further thirty.
Notarisation runs the other way, and this is the one you control. Article 28 of the Notary Public Act requires the notary to use an interpreter where the person requesting the deed does not understand Korean, Article 33(1) puts the choice with the requesting party or their agent, and Article 35(9) records the interpreter’s name and address in the deed. The trigger is the requester. Where a Korean-speaking representative director of your Korean subsidiary requests the deed, Article 28 never engages; where you request it yourself, it does, and Article 33(1) is then your lever.
Immigration reaches one setting. Article 48(6) of the Immigration Act requires an interpreter where an officer questions a suspect in an investigation, which is an enforcement interview, and it does not attach to a routine visa filing. Arbitration is a drafting question: Article 23 of the Arbitration Act lets the parties agree the language and falls back to Korean absent a tribunal designation, while Article 29 of the KCAB 2026 International Arbitration Rules has the tribunal weigh the language of the contract. Settle language in the contract, alongside the points in the guide to Korean contract law essentials.
What to Settle Before Your Next Korea Meeting
Two weeks is enough lead time for an ordinary Seoul meeting in an open week. Allow six to twelve weeks for anything falling in an exhibition week at COEX or KINTEX or in conference season, when the senior end of the Seoul market commits early, and check the lunar holiday dates before you fix travel, because Seollal and Chuseok move against the solar calendar each year and take availability out entirely. Put confidentiality, recording rights and the cancellation scale in writing before the interpreter is confirmed. Keep the same interpreter across the relationship, because the second meeting is where the glossary starts paying. Inquivix’s Korean trade show and exhibition management service covers the on-site bilingual staffing that runs alongside a booked interpreter, and the sequencing in the guide to SEMICON Korea for foreign suppliers applies to interpreter scheduling too.
Frequently Asked Questions
How much does a business interpreter cost in Korea? The Ewha Center for Interpretation and Translation lists English interpreting at 1,000,000 won per interpreter per day for up to six hours in Seoul, effective from 1 December 2023, and the HUFS Center for Interpreting and Translation lists 900,000 to 1,000,000 won by experience, VAT excluded, as published in September 2026. Agency and freelance quotes vary around those published tables.
Can I use my Korean counterpart’s employee to interpret? Treat that as a last resort. The person rendering your position would report to the company across the table, which puts them in an impossible position and gives you no way to check what was said. Korean courts appoint from their own candidate list, screened under the Supreme Court’s foreign-national case guideline, for the same structural reason. Bring your own interpreter, and accept theirs only as an addition.
Is a business interpreter in Korea required to be certified? No. Korea’s Tourism Promotion Act licenses tourist guide interpreting for travel agencies serving foreign tourists, with a fine of up to 5 million won for guiding without it, and conference or business interpreting carries no equivalent state licence. Verification comes from the graduate school and major, sector experience, association membership, and references you can call.
Getting the Language Layer Right
An interpreter is a cheap line in a Korea travel budget with an outsized effect on the outcome, and the one most often bought last and briefed never. Decide the mode, buy the right number of people, and set the register expectation out loud.
Inquivix works with global B2B companies entering Korea, across partner selection, localization and demand generation, and can sit in the room when the language layer carries commercial weight.
