Indian businesses expanding into the United States, whether through subsidiary companies, branch offices, or joint ventures, face a critical first hurdle: obtaining an Employer Identification Number from the US Internal Revenue Service. This nine-digit identifier is not optional paperwork. Under the Internal Revenue Code Section 6109, any business entity engaged in US trade or business must have an EIN before opening a US bank account, filing federal tax returns, hiring American employees, or satisfying vendor verification requirements. Without it, your US operations cannot legally receive income, pay contractors, or claim deductions on Form 1120 or 1120-S returns. In 2026, the IRS processes EIN applications through Form SS-4, with online issuance available to applicants with a US Responsible Party. KAMRIT Financial Services LLP manages the complete SS-4 preparation, IRS correspondence, and follow-up on your behalf, from document collection to delivery of your confirmed EIN letter. We handle the procedural complexity so your US market entry begins on solid legal ground.
What is USA EIN Application in India 2026?
A USA Employer Identification Number is a unique nine-digit identifier assigned by the Internal Revenue Service under Treasury Regulation Section 301.6109-1. It operates like a Social Security Number for business entities and is required for federal tax reporting, banking, and regulatory compliance in the United States. The EIN confirms your entity exists for US tax purposes and links all federal filings to your organization. Indian companies establishing US subsidiaries under the Companies Act 2013 (foreign company registration under Part I of the Companies Act), LLCs formed under state statutes, or any foreign entity earning US-source income must obtain this number before conducting business. The IRS governs EIN issuance, not the MCA, SEBI, or any Indian regulatory body. The application is submitted on IRS Form SS-4, either online through the IRS Business EIN Online Assistant (available to US-based Responsible Parties), by fax to the IRS Cincinnati office, or by mail. Foreign applicants without a US Taxpayer Identification Number file via fax or mail, attaching required identity verification documents. The EIN is valid indefinitely unless the business structure changes or the entity closes.
Who needs this
Indian businesses seeking a US EIN must meet basic criteria relating to their entity formation, US activities, and Responsible Party documentation. Both newly incorporated US entities and existing foreign businesses with US operations qualify.
- Any Indian company that has incorporated a wholly-owned US subsidiary or branch office under applicable state law (typically Delaware, California, or Texas)
- LLCs or corporations registered in a US state that need an EIN for federal tax filings, including Form 1120, 1120-S, or 1065
- Foreign business entities (including Indian LLPs and companies) with US-source income exceeding the filing threshold under Internal Revenue Code Section 6041
- Indian businesses hiring US-based employees, which triggers EIN requirement for federal employment tax withholding under IRS Publication 15
- Nonprofit organizations, trusts, or estates with a US trustee or beneficiary requiring a federal tax account number
- Indian companies applying for US bank accounts, merchant processing accounts, or credit facilities that require EIN verification
- Partnerships or joint ventures between Indian and US entities where one party is a US entity
- Entities registering with the US Securities and Exchange Commission (SEC) for securities offerings or where Indian ownership exceeds reporting thresholds
- Businesses claiming US tax treaty benefits under the India-US DTAA that require a US tax registration number
- Any entity required to file informational returns such as Form 5471 (reporting of foreign corporations) or Form 8865 (reporting of foreign partnerships)
Documents required
The IRS requires specific documentation depending on whether the applicant entity is a newly formed US entity or an existing foreign business. KAMRIT prepares the complete document package to ensure first-time approval without IRS correspondence requests.
- IRS Form SS-4 (Application for Employer Identification Number) completed in full with entity details, trade name, and responsible party information
- Passport copy of the Responsible Party (the individual who controls, manages, or directs the entity and its funds)
- PAN Card and Aadhaar Card of the Indian parent company authorized signatory applying on behalf of the US entity
- Certificate of Incorporation or Certificate of Formation from the relevant US state Secretary of State
- Operating Agreement (for LLCs) or Shareholders Agreement showing ownership structure
- Board Resolution or Shareholders Resolution from the Indian parent company authorizing US entity formation and EIN application
- Memorandum and Articles of Association of the Indian parent entity (certified copy)
- US Business Address (PO Boxes are not acceptable) for the Principal Business Address field on Form SS-4
- Indian company PAN card copy and registered office address proof for correspondence record
- Letter of Authorization on company letterhead designating KAMRIT as filing agent with signature authority for IRS communications
- Trust deed or partnership agreement if applicable to entity structure
- ITIN or SSN of Responsible Party if previously issued (for online filing facilitation)
How KAMRIT runs it, step by step
KAMRIT follows a structured five-step workflow from initial consultation through final EIN confirmation letter delivery. Each stage has defined deliverables and client responsibilities.
- Initial Consultation and Entity Verification. KAMRIT reviews the US entity formation documents (Certificate of Incorporation from the state, Operating Agreement, or partnership records) and confirms the entity type and intended US business activities. We verify that the Indian parent entity authorization documents are in order. This stage also establishes the identity and role of the Responsible Party, whose name, date of birth, and Social Security Number or ITIN will appear on Form SS-4. This consultation typically takes one business day to schedule and up to three days for document review.
- Form SS-4 Preparation and Document Compilation. KAMRIT completes IRS Form SS-4 with all required fields including Legal Name of Business, Trade Name (if different), Mailing Address, Principal Business Address (physical US location), Responsible Party details, Type of Entity, Date Business Started, Highest Number of Employees Expected, and Primary Business Activity. We cross-reference every field against the supporting documents and flag any discrepancies before submission. This preparation stage takes two to four business days depending on document completeness.
- IRS Submission via Appropriate Channel. Based on the entity profile and Responsible Party availability, KAMRIT selects the optimal filing method. For US-based Responsible Parties with SSN, we file online through the IRS Business EIN Online Assistant for same-day issuance. For foreign applicants (Indian entities without US-based Responsible Party with SSN), we file by fax to the IRS Entity and Inheritance Tax Unit in Cincinnati at 859-669-5987. The responsible party must sign Form SS-4 before submission. Fax submission takes one to two business days for IRS acknowledgment.
- IRS Processing and EIN Confirmation. For fax applications, the IRS typically issues the EIN within four to five business days, confirming via fax to the number provided on Form SS-4. Online applications receive the EIN immediately upon successful submission with a confirmation summary available for download. KAMRIT monitors IRS response windows and follows up if no confirmation is received within seven business days. If the IRS issues a Letter 147C (request for additional information), we respond promptly with the required clarification.
- EIN Letter Delivery and Operational Handoff. Once the EIN is confirmed by the IRS, KAMRIT receives the official EIN Confirmation Letter (CP 575 or equivalent digital notice) and delivers it to the client with guidance on immediate next steps. This includes opening US bank accounts (most banks require the original letter), setting up payroll tax accounts with the IRS, and registering for state-level employer identification if employees will be hired. We provide a reference dossier with the EIN, application date, and next compliance deadlines.
Timeline
From the date KAMRIT receives complete documentation and the signed Form SS-4, the process moves quickly on the IRS side. Online filings through the IRS Business EIN Online Assistant yield same-day EIN issuance, typically within hours of submission, provided the Responsible Party has a valid SSN and the US address is confirmed. Fax applications to the IRS Cincinnati office take longer: the IRS acknowledges receipt within one to two business days and issues the EIN within four to five additional business days, with the confirmation fax sent to the number listed on Form SS-4. During peak periods (January through April when tax filings are highest), processing may extend to seven to ten business days. KAMRIT controls the preparation and submission stages, completing these within five business days of receiving full documents. The IRS controls the approval stage, and we monitor and follow up as needed. On the conservative end, clients should expect the EIN confirmation letter within fifteen business days from document submission. We recommend building in a buffer if bank account opening or state registrations depend on the EIN.
How our pricing compares
KAMRIT Financial Services LLP charges $599 (approximately ₹50,000) for complete USA EIN Application service, encompassing Form SS-4 preparation, IRS submission, and confirmation follow-up. This fee encompasses professional preparation, document review, submission management, and IRS correspondence handling. It does not include government fees because the IRS does not charge a fee for EIN issuance. Several India-based compliance service providers offer similar services at lower price points. IndiaFilings charges approximately ₹15,000 to ₹25,000 for EIN application as part of US company incorporation packages. Vakilsearch prices EIN assistance between ₹18,000 and ₹22,000 when bundled with state registration. ClearTax offers EIN preparation services for ₹12,000 to ₹20,000, typically as an add-on to US tax registration services. LegalRaasta markets EIN filing from approximately ₹10,000 to ₹15,000 as a standalone service. KAMRIT's higher fee reflects end-to-end accountability: we prepare and submit Form SS-4, manage all IRS correspondence, and follow through until the EIN letter is in your hands. Lower-cost providers often leave clients to handle IRS follow-ups independently. For Indian businesses unfamiliar with US federal procedures, this managed service reduces risk of rejection, missed correspondence, and operational delay.
Common mistakes KAMRIT avoids
Indian businesses applying for a US EIN frequently encounter avoidable complications that extend timelines and require additional IRS correspondence. Most errors stem from incomplete Form SS-4 fields or incorrect Responsible Party designation.
- Listing the wrong Responsible Party: The IRS requires a specific individual (not the company) who controls, manages, or directs the entity. Listing the company itself or an authorized signatory without checking IRS criteria causes rejection.
- Using a PO Box for Principal Business Address: IRS requires a physical US street address. PO Boxes are only acceptable for mailing, not for the principal business location field.
- Incorrect entity type selection: Misclassifying an LLC as a corporation or vice versa affects subsequent tax filing requirements and state registrations. The state filing determines the entity type on Form SS-4.
- Filing online without a US Responsible Party SSN: The IRS Business EIN Online Assistant requires the Responsible Party to have a US SSN or ITIN. Attempting online filing with a foreign passport and no SSN results in immediate rejection.
- Inconsistent names between IRS form and state documents: Any variation between the legal name on Form SS-4 and the Certificate of Incorporation triggers IRS verification requests.
- Not maintaining IRS correspondence capability: The EIN confirmation is sent by fax or mail to the number provided. Businesses without a US fax line or reliable international mail access may miss the confirmation entirely.
- Submitting before US entity formation is complete: Form SS-4 must reference a valid, existing entity. Submitting before the state Certificate of Incorporation is issued causes the IRS to reject the application.
- Failing to update IRS records when entity structure changes: If the business type changes (LLC converting to corporation) or ownership transfers substantially, a new EIN may be required under Treasury Regulation 301.6109-1.
