GST Registration for South Korean Companies in India
South Korea and India share a robust economic partnership, formalized through the Comprehensive Economic Partnership Agreement (CEPA) signed in 2009. Bilateral trade between the two nations surpassed US$27 billion in 2024-25, with major Korean conglomerates like Samsung, Hyundai, LG, and Kia having established significant manufacturing and commercial operations across India. As more Korean SMEs and technology companies follow these industry leaders into the Indian market, understanding GST registration requirements becomes essential.
India's Goods and Services Tax mandates that every foreign company supplying taxable goods or services within India must register, regardless of turnover. Unlike domestic Indian businesses that enjoy threshold exemptions (₹40 lakhs for goods, ₹20 lakhs for services), Korean companies must register from their very first taxable transaction. This obligation applies whether your company operates through a wholly owned subsidiary, a branch office, a liaison office, or as a Non-Resident Taxable Person (NRTP).
Korean manufacturers investing in India under the Make in India initiative need regular GST registration from the outset, as their permanent establishment status requires full compliance with monthly GSTR-1 (outward supplies), GSTR-3B (summary return), and annual GSTR-9 filings. Korean companies providing services without a fixed place of business in India may qualify for NRTP registration under Form GST REG-09, which offers temporary 90-day registration with a security deposit equal to estimated GST liability.
How South Korea's DTAA Affects GST Registration
The India-South Korea DTAA, revised in 2015 and effective from April 2017, provides preferential withholding tax rates that complement your GST compliance strategy. The revised treaty reduced rates from 15% to 10% on royalties, fees for technical services (FTS), and interest income, making India operations more cost-effective for Korean companies.
For GST purposes, the DTAA's permanent establishment definition is critical. If your Korean company's activities in India — such as having employees working on-site for more than 183 days, a fixed place of business, or a dependent agent — trigger PE status under the treaty, you must register for regular GST rather than the more limited NRTP registration. The revised 2015 DTAA tightened PE definitions, particularly around service PEs and construction PEs.
Korean companies should also note that withholding tax at 10% on FTS under the DTAA applies to payments made by Indian entities to Korean companies for technical or consultancy services. This withholding is on gross income (direct tax), while GST (indirect tax) applies separately on the value of the service supplied. Both taxes operate independently — the DTAA does not reduce your GST obligations, but it does reduce the overall tax cost of doing business in India.
To claim DTAA benefits, Korean companies must obtain a Tax Residency Certificate (TRC) from the Korean National Tax Service and file Form 10F with Indian tax authorities. This is especially important for transfer pricing arrangements between Korean parent companies and their Indian subsidiaries.
Document Requirements from South Korea
South Korea has been a member of the Hague Apostille Convention since 2007, which simplifies document authentication for GST registration in India. All Korean corporate documents can be apostilled through the Korean Ministry of Foreign Affairs, eliminating the need for Indian embassy attestation.
Required documents for GST registration include:
- Certificate of Incorporation (사업자등록증) from the Korean company, apostilled by the Ministry of Foreign Affairs
- Business Registration Number (사업자등록번호) — Korea's equivalent of a Tax Identification Number
- Passport and visa details of the authorized signatory (must be an Indian resident with valid PAN and Aadhaar)
- Authorization letter or Power of Attorney appointing the Indian signatory, notarized in Korea and apostilled
- PAN card and Aadhaar of the authorized Indian signatory
- Proof of place of business in India — rental agreement, utility bill, or NOC from the property owner
- Bank account details — Statement or confirmation letter from an Indian bank branch
- Board resolution (이사회 결의) authorizing India operations and signatory appointment, apostilled
- Digital Signature Certificate (DSC) — Class 2 or Class 3, issued to the authorized Indian signatory
Korean-language documents must be translated into English by a certified translator. The apostille process in Korea typically takes 3-5 working days and costs approximately ₩20,000-50,000 per document.
Step-by-Step GST Registration Process
Follow this process for GST registration as a South Korean company:
- Determine registration type — Assess whether your Korea entity has or will have a permanent establishment in India. Companies with PE (subsidiary, branch, project office) apply for regular registration. Those without PE use NRTP registration.
- Appoint an authorized Indian signatory — Select an Indian resident with valid PAN and Aadhaar. This person will be the primary point of contact for the GST department and is legally responsible for compliance.
- Obtain a Digital Signature Certificate — The Indian signatory must obtain a Class 2 or Class 3 DSC from authorized certifying agencies (eMudhra, Sify, or CDAC).
- Prepare Korean documents — Collect the Certificate of Incorporation, Board Resolution, and Power of Attorney. Have all documents translated into English and apostilled through Korea's Ministry of Foreign Affairs.
- Access the GST portal — Navigate to www.gst.gov.in and select "New Registration." Choose Form GST REG-01 (regular) or Form GST REG-09 (NRTP).
- Complete Part A of the application — Enter the Indian signatory's PAN, mobile number, and email address. Complete OTP verification to receive a Temporary Reference Number.
- Fill Part B — Enter complete business details including the principal place of business in India, nature of business activity, HSN/SAC codes, and details of authorized signatories and promoters.
- Upload supporting documents — Attach all apostilled Korean documents, signatory identification proofs, address proofs, and bank details.
- Deposit GST liability (NRTP only) — If registering as NRTP, deposit the estimated GST liability for the 90-day period via the electronic cash ledger on the GST portal.
- Submit and sign with DSC — Review the application, sign electronically using the DSC, and submit. Track the Application Reference Number (ARN) on the portal.
- Await approval — Under the November 2025 GST 2.0 reforms, applications with successful Aadhaar verification receive approval within 3 working days.
Timeline and Costs
Expected timeline and costs for Korean companies registering for GST in India:
| Stage | Timeline | Estimated Cost |
|---|---|---|
| Document preparation and apostille in Korea | 5-7 days | ₩100,000-300,000 (₹6,000-18,000) |
| Certified English translation | 3-5 days | ₹5,000-12,000 |
| DSC procurement | 1-2 days | ₹1,500-3,000 |
| GST portal application filing | 1-2 days | ₹5,000-10,000 (professional fees) |
| GST officer review and approval | 3-7 working days | Nil |
| NRTP security deposit (if applicable) | Same day | Equal to estimated GST liability |
The total process takes approximately 3-5 weeks end-to-end. Korea's efficient apostille system and the November 2025 GST portal reforms make this one of the faster registration timelines among Asian countries.
Professional fees for a GST compliance specialist in India typically range from ₹10,000 to ₹25,000 for end-to-end registration support, depending on the complexity of the business structure.
Common Challenges for South Korean Companies
Korean companies frequently encounter these specific challenges during GST registration in India:
- Chaebol subsidiary structures — Large Korean conglomerates with multiple Indian subsidiaries may need separate GST registrations for each entity and each state of operation. The multi-layered corporate structure can complicate the identification of the correct registering entity.
- Manufacturing PE triggers — Korean manufacturers establishing production lines, quality control teams, or technical supervision in India often inadvertently create a PE. This can shift them from NRTP to regular GST registration mid-project.
- Input tax credit optimization — Korean companies importing capital goods and raw materials into India must carefully structure their input tax credit (ITC) claims. Customs duty IGST paid on imports is claimable as ITC, but only if the GST registration is properly set up with correct HSN codes.
- E-invoicing compliance — Companies with annual turnover above ₹5 crore must generate e-invoices through the Invoice Registration Portal (IRP) from October 2020. Korean companies scaling up quickly in India sometimes miss this threshold trigger.
- State-wise registration complexity — India requires separate GST registration in each state where a company has a place of business. Korean electronics and automotive companies with pan-India operations may need 10-20+ state registrations.
- FEMA reporting integration — Korean FDI into India requires FEMA compliance alongside GST. The Annual Return on Foreign Liabilities and Assets (FLA) and GST annual return timelines must be coordinated.
