1. Required Items and Points (225 Points): At least one item is required.

  • Intellectual property ownership (registration)
  • Intellectual property application
  • Co-inventor of owned (registered) intellectual property rights

Company types

These are the different Korean company types:

  • Sole proprietorship or Private Business (사업자 or “sa-eob-ja”)
  • Partnership Companies (합명회사 or “hab-myeong hwe-sa”)
  • Limited Partnership Companies (합자회사 or “hab-ja hwe-sa”)
  • Corporation or Stock Companies (주식회사 or “joo-shik hwe-sa”)
  • LLC or Limited Companies (유한회사 or “yu-han hwe-sa”)

Sole proprietorship

If you are thinking of a sole proprietorship, you only need to drop by a district tax office (지방세무) with the lease contract of your office and your Korean ID card (alien registration card: 외국국적등표, or 외국인 체재증) to get a business license. If your landlord agrees you can register your company at your house. Also, it is possible to register more than one person at a sole proprietorship. If you have revenue of around 50,000 USD or more, the tax rate can be quite high for a private business.


As for a corporation, you set a foundation capital and incorporate the company first to apply for a business license. For incorporation, you should go to the Seoul Global Center (서울글로벌센터) office after making an appointment or contact a local lawyer.

Seoul Global Center 38 Jong-ro, Jongno-gu, Seoul, 110-792, Korea, 110-792 서울특별시 종로구 종로 38 (서린동) 서울글로벌센터, TEL  +82 2 2075 4139  l  FAX  +82 2 723 3206

Joint stock companies are the best choice for startups, because it is relatively easy to add shareholders and issue loans like convertible bonds. Minimum starting capital for a corporation is 1 million won, roughly 1,000 US dollar. Another thing is that if you have partners you may want to sign a founders’ agreement so when things don’t go as planned you have security.

Finally, it is very important which categories (e.g. service, with sub category advertising agency) you choose to put your company under. It is quite a hassle and expensive to add categories (업태) and sub categories (종목) later. For example, you need minutes of the shareholder meeting. And, you need to go the central tax office in Gangnam.


It is not legally necessary to have an accountant as a (stock) company, but it is highly recommended. Because when you are incorporated you have to submit income tax every year, VAT returns every quarter, payroll and electronic invoices every month or you get a penalty. A Korean speaking accountant usually costs 100,000 KRW (100 USD) per month. An English speaking one often costs around 150K won.

Korean companies directory

If you are looking for a Korean companies directory, there are several:

Business registration number search

If you want to look up more info about a Korean company, most websites are in Korean. Example: Dart. Also the ones that offer data in English often do not have a database of all companies in Korea. Example: BizInKorea.

To find out if any company in Korea is active, you can check the Hometax website, officially run by the governmental National Tax Service (NTS). Hometax is where people and businesses in Korea pay / receive their tax (returns) and send electronic invoices. Unfortunately the website is only in Korean. Below are screenshots to find the status of the company in Korea. You need to input the business registration number.

  1. Dear Sir,

    Do universities in South Korea also have Certificate of business registration?

    As a foreigner invited to speak in Korea, my invitation from Chonnam National University was not enough without the Certificate of business registration.

    pls. advise

    Thank you.

    1. Hi Myra, thank you for your comment. Yes, universities also have a business registration. The Korean name spelling is: 대학교 사업자 등록증. You can find images on Google if you type that search query.

  2. Is it possible to obtain a Business registration number if my visa is D-2. I am a student but I would like to sell handmade products on Gmarket. Is there any ways to do it?

  3. Hi, how to know where exactly to find the Business Registration No. in a Korean Business Registration Cert?

  4. Hello. I want to become e-commerce (re-seller) in Korea, but wondering if only ID and Contract of office is enough. Any recommendations or info please advise) business model is in short [ finding customer through Alibaba profile > receiving an order from them > fulfilling their orders directly from China ] – I do it in SK, and receive money from customers and send to suppliers. Thanks

  5. Hi JK Song, do the same things apply for starting an online business? For example selling on Etsy? And being able to receive payments through PayPal? Thank you.

  6. Hi,
    I’m currently holding a D2 visa. Can I change it to D8-4 visa with points and then register a business with the D8-4 visa? After holding D8-4 visa for a year, it can be converted to F2-7 visa with points?
    Do you suggest sole proprietorship or company if it’s a one person ecommerce business? Would the tax amount be high?

    1. Hi Izzy, for specific questions about visa it is probably better to contact Seoul Global Center or the immigration office. Contact details of SGC are below. The corporate tax rate is lower than for sole proprietorship, but this is only when you have yearly revenue above 20-30K USD. But you may want to double check with an accountant or tax lawyer.

    1. Hi KK, if you have the company name, yes you should be able to get more info about the company in one of the directories.

  7. Hi, i want to look for a company for the shareholder ownership, may i know which website should i visit to get the information?

    Thanks so much for your help!

    1. Hi Sandy, if the company is private I think it will be very difficult to find out the shareholders. As far as I know no website publishes this info. If the company is public (stock listed), you can probably find shareholder info in their annual reports or on websites that cover these kind of companies (Yahoo/Google/Naver Finance, for example).

  8. Hey,

    Thanks for the post! Very helpful. I wanted to know how to check the license number of a Korean employment/recruiting agency?

  10. Hi – How long does it take to get a business registration number from the day all information is submitted? Thanks

    1. Hi Maryann, it could take a few days. But like all government agencies, there can be exceptions. Perhaps better to call the (local) tax office or Seoul Global Center!

      1. Thank you! I have another question, I have received a certificate, however it has a different layout than the sample above. What is the best way to confirm that the one I have is authentic.

        1. Hi Maryann, there can be different layouts for different (type of) companies as far as I know. As long as it is from the tax office I am pretty sure it is authentic.

  11. Hi Sir,

    Thanking you very much
    With regards

  13. Interesting article. However, I have a slightly different issue about which I hope you may be able to give some insight.
    I hold an F3 Spouse visa and am trying to determine how (if it is at all possible) to register a non-profit (not-for-profit) charity in Korea. Any insights on this would be greatly appreciated.

  14. Found your article very helpful. How does the VAT process works if you have a register business as a sole proprietor under f6 but have not launch your business for about a year yet or generated revenue?
    Thanks for your very informative article

    1. As long as you don’t have revenue, you don’t have to report taxes. But you may want to check with an accountant.

  15. Hi,

    I have an F-6-1 visa, and I need to get a Korean certificate of business registration. What is the lease of agreement that is needed too along with my ID?

      1. Hi,

        If i own my own place in Korea, do i bring the document of property ownership that is under my name?

        Thank you.

        1. In that case you don’t have to bring anything I think, but you may have to contact the (local) tax office. Maybe you can just tell them the address, that could be enough. Then they will verify the ownership of the property.

  16. Hi,
    Thank you for this article. If someone were to sell food online in Korea (F6 visa holder), what would be needed? I know I would have to register as a business but do I need special certificates for selling food online?
    Extras fees? If you know the answer or have a link, that would be great. Thank you.

  17. Hi. How can I find the registration number of a korean university? I need this number, but the univ didn’t reply me yet. Chungnam National University.I have found a certificate that has ‘충남대학교산학협력단’, I get confused with the 산학협력단. Is there any chance the number of this certificate is the university registration number?
    Thank you.

    1. Not sure if Korean universities have business registration numbers. But 충남대학교산학협력단 is probably not what you are looking for. You can try asking the university.

        1. Hi Romeo, I am not an expert in immigration services or an attorney. So perhaps better to ask the immigration office or Seoul Global Center.

  18. Hi there! this is amazing information! I was wondering how the tax works then for sole propiertorship with an F visa.

  19. Good day!

    Thank you so much for this wonderful article. I was wondering is it possible for someone on an E-2 visa to sell products on G-Market…etc if their business is registered under a Korean national? Would this be considered legal?
