Tax Filing for US Companies in India
Every American company operating in India through a wholly-owned subsidiary, branch office, or project office must file an annual income tax return with India's Income Tax Department. For US-owned Indian subsidiaries — which are treated as domestic companies under Indian tax law — the applicable form is ITR-6, filed electronically through the Income Tax Department's e-filing portal.
The India-US economic relationship is one of the largest bilateral corridors in the world. Over 1,600 American companies have subsidiaries or offices registered in India, spanning technology, manufacturing, financial services, and pharmaceuticals. Each of these entities must navigate India's multi-layered tax compliance framework, which includes corporate income tax, advance tax payments, tax deducted at source (TDS), goods and services tax (GST), and — critically for US-owned companies — transfer pricing documentation for every intercompany transaction with the US parent.
India's corporate tax rate for domestic companies (including subsidiaries of foreign corporations) stands at an effective 25.17% under Section 115BAA, which is competitive with global hubs like Singapore (17%) and Hong Kong (16.5%). However, companies opting for this concessional rate must forgo certain deductions and exemptions — a trade-off that requires careful analysis during each financial year's tax planning.
How the India-US DTAA Affects Tax Filing
The Double Taxation Avoidance Agreement between India and the United States, in force since 1989, is one of the most consequential treaties for American companies operating in India. The treaty governs how income is taxed across both jurisdictions and provides mechanisms to avoid paying tax on the same income twice.
For US-owned Indian subsidiaries, the DTAA impacts tax filing in several critical ways. Dividend payments from the Indian subsidiary to the US parent are subject to a maximum withholding tax of 15% under the treaty where the US parent holds at least 10% of the voting stock of the Indian company; the rate is 25% in all other cases. Without the treaty, India's domestic withholding rate would apply.
Fees for technical services and royalty payments from the Indian subsidiary to the US parent are capped at 15% under the treaty. This is particularly relevant for technology companies and those with licensing arrangements, where the Indian entity pays the US parent for use of intellectual property, software licenses, or technical know-how.
Interest payments on intercompany loans from the US parent to the Indian subsidiary are also capped at 15% withholding under the DTAA. To claim these reduced rates, the US parent must provide a valid Tax Residency Certificate (TRC) — specifically IRS Form 6166 — along with Form 10F filed on India's e-filing portal.
The treaty also addresses permanent establishment (PE) risk. If a US company's activities in India create a PE — through a fixed place of business, a dependent agent, or a service PE (where employees spend more than 90 days in India in any 12-month period) — the profits attributable to that PE become taxable in India regardless of whether a subsidiary exists.
Document Requirements from the US
US companies claiming DTAA benefits for their Indian operations must provide several authenticated documents. Since both India and the US are signatories to the Hague Apostille Convention, all documents require Apostille authentication rather than embassy attestation.
The primary document is IRS Form 6166, which serves as the US Tax Residency Certificate. To obtain Form 6166, the US parent must file IRS Form 8802 (Application for United States Residency Certification) with the IRS. Processing typically takes 4-6 weeks, and the form must be apostilled through the US Department of State in Washington, D.C., as it is a federal document signed by a Department of Treasury official.
Additional documents required include the Board Resolution from the US parent company authorizing the Indian subsidiary's tax filing, the Certificate of Incorporation of the US parent (apostilled), intercompany agreements for transfer pricing purposes, and the US parent's audited financial statements for the relevant period.
For Form 15CA/15CB compliance — required for every cross-border remittance from the Indian subsidiary to the US parent — a Chartered Accountant's certificate confirming the applicable DTAA rate must be obtained before each payment is made.
Step-by-Step Tax Filing Process
The tax filing process for a US-owned Indian subsidiary follows a structured annual cycle aligned with India's April-to-March financial year.
Step 1: Tax Regime Selection (April) — At the start of each financial year, determine whether the company should opt for the concessional tax regime under Section 115BAA (effective rate 25.17%) or continue under the old regime with available deductions. This decision is made by filing Form 10-IC and is irrevocable once exercised.
Step 2: Advance Tax Payments (Quarterly) — Pay advance tax in four installments: 15% by June 15, 45% by September 15, 75% by December 15, and 100% by March 15. Interest under Section 234C applies at 1% per month for any shortfall. Payments are made through Challan ITNS 280 on the e-filing portal.
Step 3: TDS Compliance on US Payments (Ongoing) — For every payment to the US parent or US-based vendors, deduct TDS under Section 195 at the applicable rate (domestic rate or DTAA rate, whichever is lower). File Form 15CA online and obtain Form 15CB from a Chartered Accountant before each remittance. File quarterly TDS returns on Form 27Q.
Step 4: Transfer Pricing Documentation (Year-End) — Prepare contemporaneous transfer pricing documentation for all international transactions with the US parent, including management fees, royalties, cost-sharing arrangements, and intercompany loans. File Form 3CEB — the accountant's report on international transactions — by the extended due date.
Step 5: Tax Audit and Return Filing (October-November) — Complete the statutory tax audit under Section 44AB and file the audit report by September 30. File ITR-6 by October 31 (or November 30 if transfer pricing provisions apply). Reconcile advance tax paid, TDS credits on Form 26AS, and compute final tax payable or refund due.
Timeline and Costs
The complete tax filing cycle for a US-owned Indian subsidiary spans the entire financial year, with key milestones and associated costs.
IRS Form 6166 processing: 4-6 weeks from filing Form 8802, plus 2-3 weeks for apostille through the Department of State. Plan to initiate this by January for the following assessment year.
Advance tax installments: June 15, September 15, December 15, March 15 — failure to pay on time triggers interest at 1% per month under Section 234C.
Tax audit report filing: Due by September 30 of the assessment year. The statutory audit fee for a US-owned subsidiary typically ranges from INR 2-5 lakhs depending on turnover.
ITR-6 filing deadline: October 31 for most companies; November 30 for companies with international transactions requiring transfer pricing reporting. Late filing attracts a fee of up to INR 5,000 under Section 234F.
Transfer pricing documentation: Form 3CEB filing deadline aligns with the ITR due date. Professional fees for transfer pricing study and documentation typically range from INR 3-10 lakhs depending on transaction volume and complexity.
Overall professional fees: Annual tax compliance for a mid-sized US subsidiary, including corporate tax filing, transfer pricing, TDS compliance, and GST, typically costs INR 5-15 lakhs per year.
Common Challenges for US Companies
US companies face several India-specific challenges in their tax filing obligations that differ from their experience in other jurisdictions.
Transfer pricing scrutiny: India has one of the most aggressive transfer pricing regimes globally. US-India intercompany transactions — particularly management fees, cost-sharing arrangements, and IP licensing — are frequently challenged by Indian tax authorities. Companies should maintain robust arm's-length pricing documentation and consider filing for an Advance Pricing Agreement (APA) for recurring high-value transactions.
PE exposure: US employees traveling to India for extended periods or US parent involvement in Indian operations can inadvertently create a permanent establishment, triggering additional tax obligations. The 90-day service PE threshold under the India-US DTAA requires careful tracking of employee days in India.
TRC timing: IRS Form 6166 must be obtained well in advance of TDS payment deadlines. Late TRC submission results in the Indian subsidiary withholding at the higher domestic rate rather than the treaty rate, leading to excess withholding that must be recovered through a refund claim — a process that can take 12-24 months.
New Income Tax Act 2025: India has enacted the Income-tax Act, 2025, replacing the six-decade-old Income-tax Act, 1961, effective from April 1, 2026. US companies must prepare for changes in return forms, compliance timelines, and assessment procedures under the new law.
Controlled Foreign Corporation (CFC) rules: US companies must also consider the implications of the US Global Intangible Low-Taxed Income (GILTI) regime, which taxes certain income of controlled foreign corporations — including Indian subsidiaries — at the US parent level.

Frequently Asked Questions
What tax return form does a US-owned Indian subsidiary file?
A US-owned Indian subsidiary that is incorporated in India as a private limited company files ITR-6. The subsidiary is treated as a domestic company for income tax purposes and is subject to the same filing requirements as any Indian company, including tax audit under Section 44AB if turnover exceeds the prescribed threshold.
Can a US parent company claim credit in the US for taxes paid by its Indian subsidiary?
Yes. Under the India-US DTAA and US domestic tax law, the US parent can claim a foreign tax credit for taxes paid by or on behalf of the Indian subsidiary. This includes corporate income tax, withholding tax on dividends, and any other taxes paid to the Indian government. The credit is claimed on the US parent's federal tax return.
What is the withholding tax rate on dividends paid to a US parent company?
Under the India-US DTAA, the maximum withholding tax on dividends is 15% if the US parent holds at least 10% of the voting stock (which is virtually always the case for a subsidiary). Without the treaty, India's domestic withholding rate would be higher. The US parent must provide a valid TRC (IRS Form 6166) to claim the treaty rate.
How does transfer pricing work for US-India intercompany transactions?
India requires that all international transactions between associated enterprises — including the US parent and Indian subsidiary — be conducted at arm's-length prices. The Indian subsidiary must maintain contemporaneous documentation, obtain a Chartered Accountant's certificate on Form 3CEB, and file it by the ITR due date. India recognizes six methods for determining arm's-length price, with the Comparable Uncontrolled Price (CUP) and Transactional Net Margin Method (TNMM) being most commonly used.
What happens if we miss the ITR-6 filing deadline?
Late filing of ITR-6 attracts a fee under Section 234F (up to INR 5,000), interest under Section 234A (1% per month on unpaid tax), and potential loss of the ability to carry forward business losses to future years. In extreme cases, the Assessing Officer may initiate prosecution proceedings under Section 276CC.
Is GST filing separate from income tax filing?
Yes. GST compliance is entirely separate from income tax compliance. The Indian subsidiary must file monthly or quarterly GST returns (GSTR-1, GSTR-3B) depending on turnover, and an annual GST return (GSTR-9). GST is administered by the Goods and Services Tax Network (GSTN), while income tax is administered by the Central Board of Direct Taxes (CBDT).
Do we need a separate PAN for the Indian subsidiary?
Yes. The Indian subsidiary will have its own Permanent Account Number (PAN) obtained at the time of incorporation. This PAN is used for all income tax filings, TDS payments, and advance tax payments. The US parent company may also need to obtain a separate PAN in India if it directly receives income from Indian sources beyond the subsidiary.
