USA ITIN Application in India 2026

You have US-sourced income, a US tax treaty claim, or a filing requirement with the Internal Revenue Service, but you do not qualify for a Social Security Number. Without an ITIN, the IRS will reject every return, every treaty claim, and every withholding reduction you file. In 2026, the IRS has intensified compliance checks on ITIN applications from South Asian applicants, with increased document verification requirements at the Austin Internal Revenue Campus. The solution is a properly prepared IRS Form W-7, with certified translations, consular authentication where required, and a complete supporting document package submitted to the IRS in the correct format and sequence. KAMRIT Financial Services LLP manages the entire ITIN application end to end: document checklist, IRS Form W-7 preparation, certified translation coordination, IRS submission, tracking, and liaison until the ITIN is issued and communicated to you. We remove the guesswork from a process that trips up even experienced tax professionals.

What is USA ITIN Application in India 2026?

A US Individual Taxpayer Identification Number (ITIN) is a nine-digit tax processing number issued by the Internal Revenue Service under Section 6109 of the Internal Revenue Code (26 USC). It is granted to individuals who are required to have a US taxpayer identification number but who are not eligible to obtain a Social Security Number. The primary legal instrument for obtaining an ITIN is IRS Form W-7, formally titled Application for IRS Individual Taxpayer Identification Number. The IRS Austin Internal Revenue Campus in Texas is the designated processing centre for all Form W-7 submissions globally. An ITIN does not confer work authorisation or immigration status. It is exclusively a tax administration tool. It is needed when a non-resident alien individual has US income subject to withholding, wishes to claim benefits under the US-India Double Taxation Avoidance Agreement, or is claimed as a dependent on a US tax return. The ITIN must be used on at least one US federal tax return within three consecutive years or it will expire under IRS administrative rules, requiring a fresh application.

Who needs this

ITIN eligibility is narrowly defined by IRS regulations and the instructions to Form W-7. Not every person with a US connection qualifies. Review each criterion carefully.

• Non-resident alien individual with US-sourced income subject to IRS withholding at source.
• Resident alien individual who does not meet the Substantial Presence Test or does not have US citizenship.
• Dependent or spouse of a US citizen or resident alien, claimed on Form 1040, 1040A, or 1040NR.
• Non-resident alien student, professor, or researcher claiming treaty benefits under the US-India DTAA.
• Individual seeking to claim the US-India tax treaty article 10 (dividends), 11 (interest), or 12 (royalties) reduced withholding rate.
• US real property owner with rental income who is not a US person and cannot obtain an SSN.
• Individual who has applied for or holds a valid US visa (B-1, B-2, F-1, H-1B, L-1, O-1) and has US filing requirements.
• Beneficiary of a US estate or trust that must file Form 1040-NR.
• Individual filing Form 4868 (Application for Automatic Extension of Time to File US Individual Income Tax Return) and needing an ITIN.

Documents required

The IRS accepts only specific original or certified documents that establish foreign status and identity. Documents must be current and unexpired unless they are a birth certificate.

• Valid passport (primary document accepted by IRS as sole supporting document for W-7) with biographical page and photo.
• National Resident Certificate or Aadhaar Card (only if passport is not available, with additional identity documents).
• Birth certificate (for dependent children under 18 years applying on Form W-7).
• US visa (F-1, H-1B, B-1, B-2, L-1, etc.) copy stamped by CBP on entry, for visa holders.
• US Tax Identification Number of the taxpayer claiming you as a dependent (SSN or ITIN of primary filer).
• IRS Form W-7 (completed, signed, and dated) with the specific reason code checked.
• IRS Form 8840 (Closer Connection Exception Statement for Aliens) if applicable, for treaty-based filing positions.
• IRS Form 8833 (Treaty Exemption Claim for US Source Income) if claiming DTAA article exemptions.
• Power of Attorney (Form 2848) if KAMRIT or a representative files on your behalf.
• IRS Form 8821 (Tax Information Authorization) authorising KAMRIT to receive correspondence.
• Certified English translation of any document not originally in English, prepared by a qualified translator.

How KAMRIT runs it, step by step

KAMRIT manages the ITIN application as a structured project from intake to delivery. Each step is designed to satisfy IRS documentary requirements and reduce the risk of rejection.

1. Eligibility Screening and Scope Definition. KAMRIT conducts a 30-minute intake call to determine the exact ITIN purpose: treaty claim, dependent filing, withholding relief, or tax return attachment. We confirm the applicable IRS Form W-7 reason code and identify whether a certified translation is required. This step prevents mismatched applications that the IRS returns without processing. Same day turnaround on eligibility confirmation.
2. Document Collection and Gap Analysis. We issue a personalised document checklist based on your profile. Our team reviews each submitted document for IRS compliance: unexpired dates, legible photographs, correct spellings matching across all forms. Any gaps are flagged within 48 hours of submission. For Indian residents, this typically involves coordination with your CPA or tax counsel in the US to confirm the tax return the ITIN will be attached to.
3. IRS Form W-7 Preparation and Review. KAMRIT prepares Form W-7 in accordance with the current IRS Publication 1915 (Understanding Your IRS Individual Taxpayer Identification Number) and the official W-7 instructions. We complete all fields including the filer category, country of birth, and the tax return attachment information (Form 1040-NR, Form 8833, etc.). Each form undergoes a two-reviewer check before submission. This step typically takes 2 to 3 business days.
4. IRS Submission via Certified Mail or IRS Acceptance Agent. The completed W-7 package is submitted to the IRS Austin Internal Revenue Campus. Submissions can be made via IRS-authorised Acceptance Agents (who can validate documents in-person and reduce processing time) or by certified mail directly to the IRS. KAMRIT recommends the Acceptance Agent route for clients who need faster processing given current IRS backlogs. Submission acknowledgement is provided within 5 business days of dispatch.
5. IRS Processing and Tracking. The IRS standard processing time for Form W-7 is 6 to 8 weeks from receipt at the Austin Campus. During this period, KAMRIT tracks the application using IRS correspondence and maintains email updates to the client every two weeks. If the IRS issues a 907C notice requesting additional documents or clarification, KAMRIT responds within the stipulated deadline, typically 45 days.
6. ITIN Issuance and Delivery. Once the IRS assigns the ITIN, the Notice 1392 (ITIN Assignment Letter) is mailed to the address on Form W-7 or to the Acceptance Agent. KAMRIT captures the ITIN, communicates it to the client with a formal confirmation letter, and updates any pending tax return filings that require the number. Digital delivery via encrypted email is provided within 24 hours of IRS confirmation.

Timeline

From kickoff to ITIN in hand, the realistic end-to-end timeline is 10 to 14 weeks. KAMRIT controls stages 1 through 3 and 5 through 6, which together take approximately 5 to 7 business days. The IRS controls stage 4 and 5 processing. The IRS Austin Internal Revenue Campus currently quotes 6 to 8 weeks for standard W-7 processing, though the IRS has acknowledged processing delays of up to 10 weeks during peak filing seasons (January through April). If the IRS issues a document request (IRS Notice 907C), add 4 to 6 weeks for response and resubmission. KAMRIT provides a firm deadline commitment on our controlled stages and communicates IRS delays proactively. The ITIN is valid for use on tax returns filed for the tax year of application and two subsequent years if the associated tax return is filed, after which it expires and requires renewal via a fresh W-7 application.

How our pricing compares

KAMRIT charges a flat engagement fee of USD 799 or INR 70,000 for the complete ITIN application service. This covers eligibility screening, W-7 preparation, document review, certified translation coordination, IRS submission management, and post-issuance support. Government filing fees are nil; the IRS does not charge a user fee for Form W-7. Competitor pricing varies considerably. ClearTax India offers basic ITIN application guidance starting at INR 15,000 to 25,000 but typically limits scope to form preparation without full document management. IndiaFilings quotes INR 18,000 to 35,000 for US tax identification services including ITIN support. Vakilsearch and LegalRaasta offer ITIN assistance in the INR 12,000 to 28,000 range, though service typically excludes certified translation coordination and IRS liaison. KAMRIT's higher fee reflects end-to-end accountability: we prepare and file, manage IRS correspondence, and ensure the ITIN is delivered ready for tax return attachment. The all-inclusive scope eliminates the risk of hidden charges for translations, courier, or follow-up correspondence that competitors add as line items.

Common mistakes KAMRIT avoids

IRS rejections of Form W-7 are common when applicants file without understanding IRS documentation rules. Most rejections are avoidable with proper preparation.

• Submitting an expired passport as the sole identity document: the IRS requires a currently valid passport unless using the Certified Copy of Passport method through an Acceptance Agent.
• Failing to attach the ITIN to a federal tax return: the IRS will not process a W-7 in isolation beyond the first year without a corresponding tax return, causing expiration.
• Checking the wrong reason code on Form W-7: using reason code B (dependent) when the applicant is actually a non-resident alien with treaty income results in immediate rejection.
• Not providing a certified English translation of documents in languages other than English: the IRS requires every foreign-language document to be accompanied by a full certified translation.
• Using Form W-7 instead of SS-4 to apply for an EIN: businesses and sole proprietors need an Employer Identification Number, not an ITIN, and applying for an ITIN for a business entity is incorrect.
• Sending Form W-7 directly without coordinating with the US-based tax return preparer: the IRS W-7 must reference the attached tax return, and a mismatch between the W-7 and the return causes processing delays.
• Missing the IRS Notice 907C response deadline: the IRS gives 45 days to respond to document requests; missing this deadline results in the application being closed without a refund.
• Assuming ITIN renewal is automatic: ITINs expire after three consecutive years of non-use on a tax return and require a fresh W-7 submission; there is no passive renewal process.
