Corporate Tax Filing for Companies in India

Introduction: Corporate Tax Filing for Foreign-Owned Companies in India

Corporate tax is the single largest recurring cost for any company operating in India. Getting it right — choosing the optimal tax regime, paying advance tax on schedule, correctly withholding on cross-border payments, and filing an accurate return — directly impacts the profitability and cash flow of your Indian operations. For foreign-owned companies, the stakes are higher because errors in corporate tax filing can cascade into FEMA violations, transfer pricing disputes, and complications in the home country's tax filings.

India's corporate tax system has become significantly more competitive since the 2019 reforms that introduced the concessional regime now in section 200 read with section 205(1) of the Income-tax Act, 2025 (section 115BAA of the Income-tax Act, 1961). At an effective rate of 25.17%, India now sits in a reasonable range compared to major economies — lower than the US federal rate (21% plus state taxes), comparable to the UK (25% from 2023), and competitive with key Asian hubs. For foreign-owned Indian subsidiaries, this rate is particularly attractive compared to the 36.4%-38.22% rate that applies to branch offices of foreign companies.

However, the favorable rate comes with compliance complexity. The Indian tax system requires quarterly advance tax payments, continuous TDS obligations, a mandatory tax audit, and — for companies with cross-border transactions — transfer pricing documentation with CA certification. Each of these elements has its own deadline, its own penalty structure, and its own set of forms. Coordinating all of them while running a business demands either deep in-house tax expertise or a reliable compliance partner.

What is Corporate Tax Filing?

Corporate tax filing is the process of computing a company's taxable income under the Income-tax Act, 2025, determining the tax liability at the applicable rate, and filing the income tax return (Form ITR-6) with the Central Board of Direct Taxes (CBDT) through the Income Tax Department's e-filing portal. The filing covers one financial year (April 1 to March 31) and is due in the following assessment year.

The governing legislation includes:

• Income-tax Act, 2025 — Section 4 (charge of income tax), the business-income provisions beginning at section 26 (sections 28 to 44 of the Income-tax Act, 1961), sections 200 and 201 read with section 205 (concessional rates; sections 115BAA and 115BAB of the 1961 Act), section 206 (MAT; section 115JB of the 1961 Act), section 63 (tax audit; section 44AB of the 1961 Act), sections 161 to 173 (transfer pricing; sections 92 to 92F of the 1961 Act), section 263 (filing obligation; section 139 of the 1961 Act), and sections 423, 424 and 425 (interest for defaults; sections 234A, 234B and 234C of the 1961 Act). The Income-tax Act, 1961 continues to apply to tax years beginning before 1 April 2026, so both sets of numbers are live law.
• Income Tax Rules 1962 — Prescribe forms (ITR-6, 3CA-3CD, 3CEB), computation methods, and procedural requirements
• Taxation Laws (Amendment) Act 2019 — Introduced sections 115BAA and 115BAB of the Income-tax Act, 1961 (now sections 200 and 201 of the Income-tax Act, 2025), fundamentally changing the corporate tax landscape
• Double Taxation Avoidance Agreements — Over 94 bilateral treaties that override domestic withholding rates where they provide a lower rate

Who Must File ITR-6?

Every company registered under the Companies Act 2013 or any previous Companies Act must file ITR-6. This includes:

• Private limited companies (including wholly-owned subsidiaries of foreign companies)
• Public limited companies
• One Person Companies
• Companies limited by guarantee
• Foreign companies with a branch office or project office in India

Companies claiming exemption under Section 11 (charitable/religious trusts) file ITR-7 instead of ITR-6.

Eligibility and Requirements

Tax Regime Options

Every domestic company must choose between two tax regimes:

Recommendation for foreign-owned companies: The majority of foreign-owned Indian subsidiaries — particularly in technology, services, consulting, and trading — should opt for section 200. These companies rarely claim section 138 (section 80-IA of the 1961 Act) or additional depreciation, and the simpler compliance (no MAT computation, lower rate) outweighs any theoretical benefit of the old regime. Companies with significant SEZ operations or R&D expenditure under section 45 of the Income-tax Act, 2025 (section 35 of the Income-tax Act, 1961) should model both scenarios before deciding.

Foreign Company Tax Rate

A foreign company that operates in India through a branch office or permanent establishment — without incorporating a separate Indian entity — is taxed at 35% base rate (reduced from 40% by Finance Act 2024) plus surcharge (2% if income exceeds INR 1 crore, 5% if income exceeds INR 10 crores) plus 4% cess. The effective rate ranges from 36.4% to 38.22%. This is why most foreign companies choose to incorporate an Indian subsidiary rather than operate as a branch — the tax differential alone (25.17% vs 36.4%+) justifies the additional compliance burden of maintaining a separate company. See our domestic company vs foreign company comparison for detailed analysis.

Step-by-Step Corporate Tax Filing Process

Step 1: Advance Tax Estimation and Payment (Throughout the Year)

Advance tax is the system of paying income tax in installments during the year, rather than as a lump sum after year-end. If a company's estimated tax liability (net of TDS credits) exceeds INR 10,000, advance tax is mandatory.

The quarterly schedule for FY 2026-27:

Each payment is made electronically using Challan ITNS 280 on the tin-nsdl.com portal. The company must retain the challan counterfoil (BSR code, challan serial number, date of payment) for claiming credit in the tax return.

Practical tip for foreign-owned start-ups: First-year companies often have highly variable income. Re-estimate your tax liability before each installment date and adjust payments accordingly. Overpaying advance tax ties up cash; underpaying triggers interest. A rolling quarterly forecast, shared with your tax advisor, prevents both extremes.

Step 2: TDS Compliance on Cross-Border Payments (Section 393(2))

Every payment from the Indian company to a non-resident that is chargeable to tax in India requires TDS deduction under section 393(2) of the Income-tax Act, 2025 (Table, Sl. No. 17; section 195 of the Income-tax Act, 1961). This covers:

• Royalties — 10% under most DTAAs; 20% under domestic law if no DTAA applies
• Fees for technical services (FTS) — 10% under most DTAAs; 20% domestically
• Interest on loans from foreign parent — 5-15% under DTAAs; 20% domestically for non-corporate borrowers
• Dividends to foreign shareholders — 5-15% under DTAAs; 20% domestically
• Management fees/cost recharges — Classified as FTS or business profit depending on DTAA and nature of service

For each payment, the company must:

1. Determine the applicable rate (domestic or DTAA, whichever is lower)
2. Obtain TRC and Form 41 from the non-resident recipient
3. Obtain Form 146 certification from a CA
4. File Form 145 on the Income Tax portal
5. Deduct TDS and deposit it with the government within 7 days
6. File quarterly return on Form 144
7. Issue TDS certificate (Form 16A) to the recipient

Under section 35(b)(ii) of the Income-tax Act, 2025 (section 40(a)(i) of the Income-tax Act, 1961), if TDS is not deducted on a payment to a non-resident, the entire payment is disallowed as an expense. This effectively means the company pays tax on that amount as if it were profit — a severe consequence that can dramatically increase the tax bill.

Step 3: Tax Audit (Section 63)

The tax audit is a separate requirement from the statutory audit under the Companies Act. The CA examines the company's tax computation — depreciation (using Income Tax Act rates, which differ from Companies Act rates), disallowed expenses, TDS compliance, and special provisions. The output is:

• Form 3CA — The audit report (used when the company is already audited under another law, which all Companies Act companies are)
• Form 3CD — A detailed statement of particulars covering 44 clauses, including depreciation schedules, Section 35 of the Income-tax Act, 2025 (section 40 of the Income-tax Act, 1961) disallowances, section 37 of the Income-tax Act, 2025 (section 43B of the Income-tax Act, 1961) provisions, and details of international transactions

The tax audit report must be e-filed by October 31 of the assessment year (one day before the ITR-6 due date). Failure to get the accounts audited attracts a fee of INR 75,000 / INR 1,50,000 under section 428(c) of the Income-tax Act, 2025 (section 271B of the Income-tax Act, 1961); the earlier 0.5%-of-turnover penalty no longer applies.

Step 4: Transfer Pricing Documentation (Sections 161 to 173)

This step applies to any company with international transactions with associated enterprises. The transfer pricing framework requires:

• Documentation — A contemporaneous report analyzing each international transaction, applying the most appropriate method (Comparable Uncontrolled Price, Resale Price, Cost Plus, TNMM, or Profit Split), and benchmarking against comparable transactions or entities.
• Form 48 — CA certification filed by 31 October, one month before the 30 November ITR deadline for transfer-pricing cases, listing every international transaction and confirming the arm's length price.
• Master File — Required if the parent group has consolidated revenue exceeding INR 500 crores, filed by November 30.
• Country-by-Country Report (CbCR) — Required if the parent group has consolidated revenue exceeding INR 6,400 crores (approximately EUR 750 million; updated from INR 5,500 crores effective April 1, 2021), filed on Form 3CEAC/3CEAD/3CEAE.

The Indian Transfer Pricing Officer (TPO) has broad powers to adjust the arm's length price, and adjustments are common in assessments. Robust documentation is the strongest protection. Consider applying for an Advance Pricing Agreement (APA) if your company has recurring, significant international transactions — this provides certainty for up to 5 years.

Step 5: ITR-6 Preparation and Filing

The ITR-6 form is extensive. Key schedules include:

• Schedule BP — Computation of business income
• Schedule HP — Income from house property (if the company owns real estate)
• Schedule CG — Capital gains
• Schedule OS — Income from other sources (interest, dividends received)
• Schedule MAT — MAT computation under Section 206 (not required for Section 200 companies)
• Schedule TP — Transfer pricing details
• Schedule SH — Shareholding pattern
• Schedule FA — Foreign assets (if the company has any overseas holdings)
• Schedule ESR — Details of income distributed as dividend

The return must be e-filed and verified using the director's Digital Signature Certificate (DSC). After filing, the system generates an acknowledgment (ITR-V). The CPC at Bengaluru processes the return under section 270(1) of the Income-tax Act, 2025 (section 143(1) of the Income-tax Act, 1961), and an intimation is sent typically within 3-6 months — either confirming the return or raising adjustments.

Documents Required

For All Companies

• Audited financial statements with schedules and notes
• Tax audit report (Form 3CA-3CD)
• Depreciation chart showing both Companies Act and Income Tax Act depreciation
• Bank statements for all accounts
• TDS certificates (Form 16A, Form 168 (formerly Form 26AS)/AIS reconciliation)
• Advance tax challans with BSR codes
• GST returns reconciled with books
• Board resolution approving the tax return filing

Additional for Foreign-Owned Companies

• Transfer pricing study and benchmarking report
• Form 48 (CA certificate for international transactions)
• Inter-company agreements — management services, royalty, technical services, loans
• TRC and Form 41 from non-resident recipients of payments
• Forms 145 and 146 records for all outward remittances
• Form 144 (quarterly TDS return for non-resident payments)
• DTAA treaty articles being relied upon for reduced withholding
• FC-GPR and share capital records to verify the capital structure reported in ITR-6

Key Regulations and Legal Framework

Income-tax Act, 2025 — Key Sections

DTAA Framework

India has signed Double Taxation Avoidance Agreements with over 94 countries. Key treaty partners for foreign investors include Singapore, Mauritius, the US, the UK, the Netherlands, Japan, Germany, and the UAE. DTAAs typically reduce withholding tax rates on dividends (5-15%), interest (10-15%), and royalties/FTS (10-15%) compared to domestic rates of 20%. The treaty benefit is claimed by the non-resident recipient, but the Indian company (as the payer and withholding agent) must verify eligibility and apply the correct rate.

Foreign-Specific Considerations

Section 200 vs Foreign Company Rate

This distinction cannot be overstated: an Indian-incorporated company with 100% foreign ownership pays 25.17% under section 200. A foreign company operating through a branch in India pays 36.4% to 38.22%. The difference on INR 10 crore of taxable income is approximately INR 1.1 crores per year. This is why most foreign companies setting up in India incorporate a separate wholly-owned subsidiary rather than register a branch office.

Transfer Pricing Exposure

Foreign-owned Indian companies are prime targets for transfer pricing scrutiny by the Income Tax Department. If your Indian subsidiary pays management fees, royalties, or technical service fees to the foreign parent, the TPO will examine whether these payments are at arm's length. Common adjustments include:

• Reduction or elimination of management fees on grounds that equivalent services are not being received
• Adjustment of royalty rates using comparable license agreements
• Recharacterization of guarantee fees paid to the parent
• Adjustment of interest rates on inter-company loans

Each adjustment directly increases taxable income in India. An Advance Pricing Agreement or Safe Harbour Rules can provide certainty, but require advance planning.

DTAA Treaty Benefit Claims

When the Indian company makes payments subject to withholding tax, it must determine whether a DTAA provides a lower rate. This requires the non-resident recipient to provide a valid Tax Residency Certificate and Form 41. Indian tax authorities have heightened scrutiny of treaty benefit claims — particularly for entities in Mauritius, Singapore, and other jurisdictions historically used for treaty shopping. The GAAR provisions (sections 178 to 184 of the Income-tax Act, 2025; sections 95 to 102 of the Income-tax Act, 1961) can be invoked to deny treaty benefits if the arrangement lacks commercial substance.

Double Taxation Relief

Corporate tax paid in India is generally creditable against the tax liability in the foreign shareholder's home country. However, the mechanics differ by jurisdiction — the US uses a foreign tax credit system, the UK uses credit relief, and some countries use exemption methods. The Indian company's tax computation documents are essential for the foreign parent's home-country tax filing.

Dividend Withholding and Repatriation

Since April 2020, dividends are taxed in the hands of shareholders, not the distributing company. When an Indian company pays dividends to foreign shareholders, it must withhold tax at 20% (domestic rate) or the applicable DTAA rate (commonly 10-15%). The company must file Forms 145 and 146 for each dividend remittance. The authorized dealer bank verifies compliance before processing the outward remittance.

Benefits and Advantages

1. India's competitive 25.17% effective rate positions foreign-owned subsidiaries favorably against branch offices and many competing jurisdictions. Proper tax filing ensures you actually receive this benefit.
2. Loss carry-forward preservation — Filing on time is the only way to carry forward business losses for up to 8 years. For start-ups expecting profitability in later years, this is critical.
3. DTAA credit maximization — Accurate Indian tax computation enables maximum credit utilization in the foreign parent's home country, reducing the overall global tax cost of Indian operations.
4. Transfer pricing certainty — Proactive documentation protects against TP adjustments that can add crores to taxable income.
5. Advance tax optimization — Proper quarterly planning prevents both interest charges (from underpayment) and cash flow drain (from overpayment).
6. Refund acceleration — Accurately computed returns with proper TDS credits result in faster refund processing from the CPC.
7. Reduced assessment risk — Clean returns with full disclosures are less likely to be selected for scrutiny assessment.
8. Dividend distribution readiness — Only a company with filed returns and no outstanding tax demands can smoothly distribute and repatriate dividends to foreign shareholders.

Common Mistakes to Avoid

• Not deducting TDS on payments to the foreign parent — This is the most expensive mistake. Under section 35(b)(ii) of the Income-tax Act, 2025 (section 40(a)(i) of the Income-tax Act, 1961), the entire payment is disallowed as an expense. A INR 50 lakh management fee without TDS becomes INR 50 lakh of additional taxable income — resulting in approximately INR 12.58 lakh in extra tax plus interest and penalty.
• Opting for Section 200 without analyzing MAT credit impact — Companies that have paid MAT in prior years accumulate MAT credit. This credit cannot be used under section 200 and lapses permanently. If the accumulated credit is substantial, staying on the old regime until the credit is exhausted may be more tax-efficient.
• Missing advance tax installments — Start-ups and newly established subsidiaries sometimes pay all tax at year-end. This triggers Section 425 interest on each missed installment. Even if you are unsure of your tax liability, paying conservative estimates on time is cheaper than the interest.
• Incorrect DTAA article citation in Form 146 — Citing the wrong article of the DTAA when withholding tax on cross-border payments can result in the lower rate being challenged during assessment. Each type of payment — dividend, interest, royalty, FTS — has a specific DTAA article.
• Not reconciling Form 168/AIS with books — The Annual Information Statement (AIS) contains TDS credits, advance tax payments, and transaction data reported by third parties. Mismatches between AIS data and the tax return trigger automated adjustments by the CPC.
• Late filing leading to loss of carry-forward — Under section 121 of the Income-tax Act, 2025 (section 80 of the Income-tax Act, 1961), business losses can only be carried forward if the return is filed on or before the due date. A belated return filed after October 31 forfeits this right — devastating for start-ups with initial-year losses.
• Ignoring Form 48 for 'small' international transactions — There is no minimum threshold for transfer pricing. Even a INR 1 lakh management fee to the parent company triggers the Form 48 requirement. Non-filing results in a fee under section 428(d) of the Income-tax Act, 2025 (section 271BA of the Income-tax Act, 1961) of INR 50,000, rising to INR 1,00,000.

Timeline and What to Expect

The core tax filing work — computation, audit report, transfer pricing documentation, and ITR-6 filing — is concentrated in September through November. Companies that maintain clean books throughout the year and reconcile TDS quarterly experience a much smoother filing season.

Comparison with Alternatives

Subsidiary vs Branch Office Tax Filing

A subsidiary files ITR-6 at 25.17% effective tax rate; a branch office files at 36.4%-38.22%. The branch office return is technically simpler (no separate Indian entity accounts), but the tax cost is dramatically higher. Additionally, a branch office creates a permanent establishment by definition, which the parent company may want to avoid in other contexts.

Company vs LLP Tax Filing

An LLP files ITR-5 at a flat 30% rate (plus 12% surcharge if income exceeds INR 1 crore, plus 4% cess) — with no concessional regime equivalent to section 200. The effective LLP tax rate ranges from 31.2% to 34.94%, compared to 25.17% for a company under section 200. LLPs have a simpler compliance structure but a higher tax cost. For foreign investors, the restriction on FDI in LLPs in certain sectors further limits the LLP option.

Old Regime vs New Regime

The choice between old and new regime should be modeled numerically. Create a spreadsheet with your company's specific income, deductions claimed under the old regime, MAT credit balance, and expected future income. If the deductions foregone under section 200 amount to less than the rate differential (approximately 1-10 percentage points depending on income level), the new regime wins. For most services and technology companies, this is a straightforward decision in favor of section 200.
