1. Key Definitions in International Taxation

Before diving into rules and treaties, understanding these fundamental concepts is essential. International taxation rests on a precise vocabulary — a single word can change your entire tax liability.

🏠
Residence
Tax Residency
The country where a taxpayer (individual or company) is considered "at home" for tax purposes. Residents are taxed on worldwide income; non-residents are taxed only on source-country income.
📍
Source Rule
Source Country
The country where income originates or is derived from — e.g., where services are performed, where property is located, or where a payer is resident. Source countries have a primary taxation right.
🏢
PE
Permanent Establishment
A fixed place of business through which a foreign enterprise carries out business in a country. The trigger point for taxing business profits in the source country. Includes offices, factories, construction sites exceeding thresholds.
🤝
DTAA
Double Tax Avoidance Agreement
A bilateral treaty between two countries that allocates taxing rights to prevent the same income from being taxed twice. Also called Tax Treaties or Double Tax Treaties (DTTs).
💱
TP
Transfer Pricing
The pricing of transactions between related entities (e.g., parent-subsidiary) across borders. Tax authorities require these prices to follow the Arm's Length Principle — as if the parties were unrelated.
💸
WHT
Withholding Tax
Tax deducted at source by the payer on payments like dividends, interest, royalties, and fees paid to non-residents. DTAA treaties typically reduce WHT rates significantly.
🛡️
BEPS
Base Erosion & Profit Shifting
Tax planning strategies used by multinationals to shift profits to low-tax jurisdictions and erode the tax base of high-tax countries. The OECD's 15-action BEPS plan combats this.
🌍
GloBE
Global Minimum Tax (Pillar Two)
OECD's 2021 framework ensuring large MNCs pay a minimum effective tax rate of 15% globally. Countries with low-taxed profits face a "top-up tax" to bridge the gap.
🔍
FATCA
Foreign Account Tax Compliance Act
US law requiring foreign financial institutions to report US person accounts to the IRS. Non-compliant FFIs face a 30% withholding on US-sourced payments.
🔗
CRS
Common Reporting Standard
OECD's global standard for automatic exchange of financial account information between tax authorities. Over 100 countries participate, sharing data annually on foreign account holders.
🏛️
MAP
Mutual Agreement Procedure
A dispute resolution mechanism in tax treaties allowing the competent authorities of two countries to resolve double taxation or treaty interpretation disputes through negotiation.
📋
ALP
Arm's Length Principle
The internationally accepted standard for transfer pricing — transactions between related parties must be priced as though they were conducted between unrelated parties under comparable circumstances.
🎯
LOB
Limitation of Benefits Clause
A treaty anti-abuse provision that restricts treaty benefits to residents who have a genuine economic connection to a treaty country — preventing "treaty shopping" by third-country residents.
📊
CbCR
Country-by-Country Reporting
BEPS Action 13 requirement for MNCs with revenue ≥ €750 million to file a CbC report showing revenue, profit, taxes paid, and employees in each jurisdiction of operation.
⚖️
GAAR
General Anti-Avoidance Rule
A domestic law provision allowing tax authorities to override transactions that lack commercial substance and are primarily designed to obtain a tax advantage. India's GAAR is in Chapter X-A of the Income Tax Act.
🏦
FFI
Foreign Financial Institution
Non-US banks, brokers, investment funds, insurance companies, and similar entities that are subject to FATCA compliance requirements when they hold US person accounts.

2. DTAA & International Tax Treaties

A Double Tax Avoidance Agreement is a bilateral contract between two sovereign nations that determines which country has the right to tax various categories of income. Without DTAAs, a company earning income abroad could be taxed twice — once in the source country and again in the residence country.

💡 The India Advantage: India has signed over 94 comprehensive DTAAs and 22+ limited treaties (for shipping/air transport). Treaty rates often reduce withholding tax on dividends from 20%–30% domestic rates down to 5%–15%, sometimes even lower.

⚠ Treaty Shopping Watch: Since the OECD MLI (Multilateral Instrument) came into force, treaty shopping through intermediate holding companies (Mauritius, Singapore, Netherlands route) has been severely curtailed. The Principal Purpose Test (PPT) in MLI can deny treaty benefits if a key purpose of the arrangement was to obtain treaty advantages.

Methods to Eliminate Double Taxation

🚫
Exemption Method
The residence country exempts foreign-source income from tax entirely. The source country taxes, and the resident keeps the difference. Common in territorial tax systems (Netherlands, Singapore).
💳
Credit Method
The residence country taxes worldwide income but gives a credit for taxes paid in the source country. The credit is limited to the residence country's tax on that income. Used by USA, UK, India.
➗
Deduction Method
Foreign taxes paid are deducted as a business expense (not a direct credit). Less favourable than the credit method, but sometimes used as a fallback when no treaty exists.

3. Permanent Establishment (PE) Rules

Permanent Establishment is the gateway concept. A source country can only tax a foreign enterprise's business profits if that enterprise has a PE in the source country. This makes PE determination one of the most contested issues in international tax.

🚨 Digital Economy Alert: Traditional PE rules were built for physical presence. In the digital economy, companies like Google, Amazon, and Netflix earn billions without any physical PE. BEPS Action 7 and Pillar One aim to address this gap with new nexus rules.

Types of Permanent Establishment

Fixed Place

Fixed Place of Business PE (Article 5(1) OECD)

A place of business through which the business of an enterprise is wholly or partly carried on — office, factory, workshop, mine, oil well, quarry. Must be fixed (specific location), must be "of the enterprise" (not temporary use), and must be a place "through which business is carried on".

Construction

Construction Site PE (Article 5(3) OECD)

A building site, construction, or installation project constitutes a PE only if it lasts more than 12 months (OECD Model). Many India DTAAs use 6 months or 9 months threshold. Artificially splitting contracts to stay below the threshold is addressed by BEPS Action 7.

Agency

Agency PE (Article 5(5)/(6) OECD)

When a person (agent) habitually exercises authority to conclude contracts on behalf of a foreign enterprise, that enterprise is deemed to have a PE through that agent. Independent agents acting in the ordinary course of their business are excluded.

Service

Service PE (India-specific)

Many of India's DTAAs include a "Service PE" provision — if a foreign enterprise provides services in India for more than a threshold period (typically 90–183 days in 12 months), a PE is triggered. This is beyond the standard OECD model and is common in India-US, India-Singapore treaties.

Digital

Significant Economic Presence (India's Digital PE)

India introduced "Significant Economic Presence" (SEP) in 2018 (Section 9 of IT Act) — a non-resident has SEP in India if transactions exceed ₹2 crore or it has 300,000+ users. This goes beyond traditional DTAA PE rules and targets digital businesses.

PE Exceptions — Safe Harbours

Article 5(4) of the OECD Model Treaty lists activities that specifically do not create a PE:

  • Using facilities solely for storage, display, or delivery of goods
  • Maintaining a stock of goods solely for storage, display, or delivery
  • Maintaining a fixed place solely to purchase goods or collect information
  • Maintaining a fixed place solely for advertising, supply of information, scientific research, or other preparatory/auxiliary activities
  • Any combination of the above activities, if the overall activity remains preparatory or auxiliary in character
⚠ Post-BEPS Change: BEPS Action 7 added an "anti-fragmentation rule" — if multiple entities of the same group have complementary functions and, taken together, go beyond preparatory/auxiliary, none of them can claim the Article 5(4) exemption. This prevents artificial fragmentation of a single business operation.

4. Transfer Pricing

When a company in India sells goods to its subsidiary in Singapore, what price should it charge? If the price is artificially low, profits shift to Singapore where taxes may be lower. Transfer Pricing rules prevent this by requiring the Arm's Length Price (ALP) — the price that independent parties would agree on in similar circumstances.

The Arm's Length Test
Transfer Price (Actual) =?= Arm's Length Price (Comparable Market)
If Actual Price < ALP → Income is adjusted upward (addition to income)
If Actual Price > ALP → Usually no downward adjustment (asymmetric rule)

Prescribed Transfer Pricing Methods

MethodAbbreviationBest Used ForHow It Works
Comparable Uncontrolled Price CUP Commodities, simple goods Compare price in related-party transaction with price in comparable uncontrolled transaction
Resale Price Method RPM Distribution/wholesale Start with resale price to independent buyer; subtract gross margin; residual is ALP
Cost Plus Method CPM Manufacturing, services Start with cost of goods/services; add appropriate markup; result is ALP
Profit Split Method PSM Highly integrated operations, intangibles Split combined profits of related parties in proportion to their relative contributions
Transactional Net Margin Method TNMM Most common method globally Compare net profit margin of tested party to comparable independent companies
Other Methods (Residual) Other Unique situations Any method that gives the most reliable measure of ALP where above methods are inapplicable

India's Transfer Pricing Thresholds & Documentation

Form 3CEB

Mandatory TP Report — All International Transactions

Any taxpayer undertaking international transactions with associated enterprises must get a TP Report (Form 3CEB) certified by a Chartered Accountant and file it with the income tax return. Threshold: international transactions exceeding ₹1 crore in aggregate.

CbCR

Country-by-Country Report — Revenue ≥ ₹5,500 Crore

Indian ultimate parent entities of multinational groups with consolidated revenue ≥ ₹5,500 crore (approx. €750M) must file CbCR (Form 3CEAD). Shared with other tax authorities under automatic exchange agreements.

APA

Advance Pricing Agreement — Certainty Tool

Taxpayers can enter into an APA with the CBDT to fix the ALP methodology for future transactions for up to 5 years. Bilateral APAs (BAPAs) involve two countries and provide the highest certainty. India has concluded 400+ APAs as of 2024.

🌍 Global Context — Pillar One on Profit Allocation: OECD's Pillar One (Amount A) proposes to reallocate 25% of the residual profit of the largest MNCs (revenue > €20B, profitability > 10%) to market jurisdictions based on sales — regardless of physical presence. This represents the most radical change to international profit allocation rules since 1920s.

5. Withholding Tax (WHT) on Cross-Border Payments

When an Indian company pays interest, dividends, royalties, or technical service fees to a foreign company, it must withhold tax at source. The applicable rate depends on whether a DTAA applies and which rate is lower — domestic rate or treaty rate.

✅ Key Rule — Section 90(2) of IT Act: Under Indian law, a non-resident taxpayer can choose the more beneficial of the domestic tax rate or the applicable DTAA rate. Always compare both and apply the lower of the two.
Payment TypeDomestic Rate (Section)Typical DTAA RateWith PAN / TRC
Dividends 20% + Surcharge 5%–15% DTAA rate available with TRC + Form 10F
Interest (general) 20% + Surcharge 10%–15% DTAA rate available
Royalties / FTS 20% + Surcharge 10%–15% DTAA rate available
Capital Gains (STCG on listed) 15% Varies by treaty Mauritius/Singapore pre-2017: NIL
Technical Service Fees (Sec 194J) 10% (domestic) 10%–15% Many treaties don't have FTS clause
No PAN furnished Higher of 20% or applicable rate DTAA benefit denied Sec 206AA override

How to Claim Treaty WHT Benefits — Checklist

  • Obtain a valid Tax Residency Certificate (TRC) from the foreign payee's home country tax authority
  • Collect Form 10F self-declaration from the payee (as per CBDT requirements)
  • Verify PAN or provide certificate under Section 195(2)/(3) for reduced deduction
  • Ensure payee is the "Beneficial Owner" of the income — not merely a conduit
  • Check LOB / PPT clause in the relevant DTAA — ensure treaty shopping protection is met
  • Deduct at applicable rate and file TDS return with Form 27Q within due dates
  • Issue Form 16A (TDS certificate) to the foreign payee

6. BEPS — The 15 Action Plan

The OECD's Base Erosion and Profit Shifting (BEPS) project, launched in 2013 and delivering outputs by 2015, is the most significant reform to international tax rules in a century. It consists of 15 Action points designed to close gaps exploited by MNCs.

🔑 The MLI — A Game Changer: The Multilateral Convention to Implement Tax Treaty Related Measures to Prevent BEPS (MLI) allows countries to amend thousands of their existing bilateral tax treaties simultaneously by ratifying a single instrument. As of 2025, 137+ jurisdictions have signed the MLI. India has adopted the MLI with reservations, including opting into the mandatory arbitration provision.

7. OECD Pillar Two — Global Minimum Tax (15%)

The most dramatic shift in international taxation since the 1920s. Under the Two-Pillar Solution agreed by 140+ countries in October 2021, large MNCs will pay a minimum effective tax rate of 15% in every country they operate in.

📌 Who Does It Apply To? Pillar Two (GloBE rules) applies to MNC groups with annual consolidated revenue ≥ €750 million. The rules began phasing in from January 2024 for early adopter countries (EU, South Korea, Japan, UK). India is expected to implement its own Qualified Domestic Minimum Top-up Tax (QDMTT) soon.
COMPONENT 01
Income Inclusion Rule (IIR)
Parent company pays a top-up tax on the low-taxed income of its subsidiaries. Applied first at the ultimate parent level, cascading down through intermediate parents.
COMPONENT 02
Undertaxed Profit Rule (UTPR)
Backstop rule — if the parent jurisdiction doesn't apply the IIR, other group jurisdictions can collect the remaining top-up tax through denying deductions or making equivalent adjustments.
COMPONENT 03
Qualified Domestic Minimum Top-up Tax (QDMTT)
Countries can introduce their own domestic minimum tax at 15%. The domestic tax gets "credit" against IIR/UTPR — keeping the revenue in the source country rather than letting it flow to the parent's jurisdiction.
EXCLUSION
Substance-Based Income Exclusion (SBIE)
Carve-out for genuine substance: 5% of payroll costs + 5% of tangible assets are excluded from GloBE income (reducing to 5% each by 2033). Rewards real economic activity.
COMPUTATION
Effective Tax Rate (ETR) Calculation
ETR = Covered Taxes / GloBE Income. Computed jurisdiction-by-jurisdiction (not entity-by-entity). Top-up Tax = (15% − ETR) × Excess Profit above SBIE exclusion.
SAFE HARBOUR
Transitional CbCR Safe Harbour
For FY2024–2026: If a jurisdiction's CbCR shows ETR ≥ 15%, or profit is de minimis, or it's a loss jurisdiction — simplified calculations apply, reducing compliance burden.
GloBE Top-Up Tax Formula
Effective Tax Rate (ETR) = Covered Taxes ÷ GloBE Net Income
Top-Up Tax % = MAX(0, 15% − ETR)
Excess Profit = GloBE Net Income − Substance-Based Income Exclusion
Top-Up Tax Amount = Top-Up Tax % × Excess Profit
🇮🇳 India's Position: India has not yet enacted domestic GloBE legislation (as of 2025), but the Finance Ministry has indicated intent to implement a QDMTT to retain revenue. India's BEPS implementation through domestic law (Equalisation Levy, SEP rules, Master File/CbCR) continues to evolve. Businesses operating in India must monitor developments closely.

8. FATCA & CRS — Global Information Sharing

The era of banking secrecy is over. FATCA (a US law) and CRS (an OECD standard) create a global web of automatic information exchange, meaning your offshore bank account details are shared with your home country's tax authority annually.

🇺🇸
FATCA (2010)
Foreign Account Tax Compliance Act
Who: US persons with foreign accounts. What: FFIs must identify and report US person accounts to the IRS. Non-compliant FFIs face 30% WHT on US payments. India signed FATCA IGA in 2015.
🌍
CRS (2014)
Common Reporting Standard
Who: Anyone with offshore accounts. What: 110+ countries automatically exchange account information annually. Financial institutions report foreign account holders' details to their own government, which shares with the account holder's residence country.

What Information Is Exchanged?

  • Account Holder Details: Name, address, date of birth, TIN (Tax Identification Number)
  • Account Information: Account number, account balance or value at year-end
  • Income Payments: Interest, dividends, and other income credited to the account
  • Gross Proceeds: Proceeds from sale of financial assets flowing through the account
  • Controlling Persons: For entities — details of beneficial owners / controlling persons
🚨 Indian Black Money Law: Non-disclosure of foreign assets under FATCA/CRS data leads to proceedings under the Black Money (Undisclosed Foreign Income and Assets) and Imposition of Tax Act, 2015. Penalties: 300% of undisclosed asset value + ₹10 lakh additional penalty + possible prosecution.

These landmark cases have shaped how international tax law is interpreted and applied globally and in India. Click the links to access official/reporting sources.

India · SC

Vodafone International Holdings BV v. Union of India (2012)

Vodafone's acquisition of Hutchison's Indian telecom business through a share transfer in the Cayman Islands — could India tax the capital gains? Supreme Court held that the transaction was structured outside India and India had no jurisdiction to tax it under the then-existing law. Led to the controversial retrospective amendment to Section 9(1)(i) of the IT Act, and ultimately the 2021 reversal.

✅ Ruling: No jurisdiction to tax offshore share transfer of foreign holding company. Led to Pillar One discussions globally.

Engineering Analysis Centre of Excellence Pvt. Ltd. v. CIT (2021)

Whether payments made by Indian companies to foreign companies for purchase of software (copyrighted articles) constitute "royalties" taxable in India. Supreme Court held in a landmark 5-judge bench ruling that such payments are NOT royalties — they are payments for copyrighted articles, not use of copyright. This reversed a decade of conflicting AAR and High Court rulings.

✅ Ruling: Software purchase payments ≠ Royalty. Massive relief for Indian IT industry and foreign software companies.

India · Delhi HC

DIT v. Morgan Stanley & Co. Inc. (2007) — Supreme Court

Morgan Stanley's Indian subsidiary (MSAS) was a captive service provider to the US parent. The question was whether MSAS itself could be a PE of Morgan Stanley, and whether the stewardship activities of visiting US employees created an additional PE. SC held that MSAS being compensated at arm's length would not create any further tax liability (no attribution beyond ALP); but stewardship functions beyond mere supervision did constitute agency PE.

✅ Ruling: Arm's length compensation to Indian sub = no further PE attribution. Stewardship ≠ PE trigger.

India · AAR

Azadi Bachao Andolan v. Union of India (2003) — Supreme Court

The constitutional validity of the India-Mauritius DTAA and the infamous "Mauritius route" for capital gains exemption was challenged. SC upheld the DTAA and the capital gains exemption, famously saying that "treaty shopping is not something that the legislature in India has prohibited." This kept the Mauritius route alive until the 2016 renegotiation.

✅ Ruling: Mauritius DTAA valid; treaty shopping not prohibited at that time. Spurred later renegotiation (2016).

Supreme Court ↗
EU · ECJ

Apple Inc. v. European Commission (ECJ, 2024)

The European Commission in 2016 ordered Apple to repay €13 billion in allegedly illegal state aid to Ireland, claiming Ireland's tax rulings allowed Apple to pay an effective tax rate of 0.005%. After lengthy litigation, the European Court of Justice (Grand Chamber) in September 2024 upheld the Commission's ruling, ordering Apple to repay the full €13 billion. A landmark victory for the principle that preferential tax deals can constitute illegal state aid.

✅ Ruling: Apple must repay €13B to Ireland. Landmark for EU state aid and transfer pricing.

ECJ ↗
OECD / UN

Google LLC — French DST & Permanent Establishment (France, 2019–2022)

French tax authority argued Google had a PE in France through its Irish subsidiary's digital activities. The Paris Administrative Court initially found no PE (2019). However, France separately enacted a Digital Services Tax (DST) in 2019, taxing digital revenues at 3% — outside the treaty framework — leading to disputes that later influenced OECD Pillar One negotiations for market jurisdiction taxation rights.

⚠ Outcome: No PE found under traditional rules; prompted Pillar One reform for digital taxation globally.

OECD BEPS ↗
India · SC

Union of India v. Cairn Energy (Retrospective Tax Settlement, 2021)

Following the controversial retrospective amendment to Section 9(1)(i) (post-Vodafone), India taxed Cairn Energy's 2006 internal restructuring. Cairn won international arbitration under the India-UK DTAA; the arbitral tribunal awarded €1.2 billion in damages against India. India eventually repealed the retrospective amendment in 2021 (Taxation Laws (Amendment) Act 2021) and refunded all taxes collected under it — a landmark retreat on fiscal sovereignty vs. treaty obligations.

✅ Ruling: India repeals retrospective tax; refunds collected tax. Major precedent on treaty arbitration vs. sovereign taxation.

CBDT ↗
USA · Tax Court

Coca-Cola Company v. Commissioner (US Tax Court, 2023)

The IRS argued that Coca-Cola's royalty payments from its foreign affiliates for use of Coca-Cola's intangibles (formula, brand, marketing) were underpriced, understating US taxable income. US Tax Court ruled largely in the IRS's favour, upholding billions in transfer pricing adjustments and highlighting the difficulty of valuing unique intangible assets under the arm's length standard.

✅ Ruling: IRS adjustments largely upheld; intangible valuation remains the hardest TP problem globally.

10. Sample Case Studies — International Tax in Action

These real-world scenarios illustrate how international tax principles play out in practice. Understand the facts, the tax issue, and the outcome.

Case Study 01 · Withholding Tax & DTAA
TechIndia Ltd pays ₹10 Crore Software License Fee to US Company
India–USA DTAA · Royalty · Section 195
1
The Facts
TechIndia Ltd (Bengaluru) pays ₹10 crore per year to SoftCorp Inc. (Delaware, USA) for a perpetual license to use its enterprise software. SoftCorp does not have any office, employees, or operations in India.
2
The Tax Issue
Is this payment a "royalty"? If yes, TechIndia must withhold tax before paying SoftCorp. Under Indian domestic law (Section 115A), royalties are taxed at 20% (+ surcharge/cess ≈ 21.84%). Under the India-US DTAA, the rate is 10%/15% depending on the type of royalty.
3
Post Engineering Analysis (SC 2021) Position
If TechIndia is buying the right to use the software (i.e., not just buying a copy), the payment qualifies as royalty. If it's merely buying a copy of a copyrighted article, post-Supreme Court ruling in Engineering Analysis, it is NOT royalty. Assume here it's a license for commercial exploitation — qualifies as royalty.
4
Tax Calculation
SoftCorp provides TRC (Tax Residency Certificate) from US + Form 10F.
DTAA Rate: 15% on royalties (India-US treaty).
Domestic Rate (Sec 115A): ≈ 21.84% (with surcharge & cess).
Apply lower: 15% × ₹10 Cr = ₹1.5 Crore to be withheld.
Outcome TechIndia deducts ₹1.5 Crore WHT, pays ₹8.5 Crore net to SoftCorp, files Form 27Q, issues Form 16A. SoftCorp claims credit in its US return. Net tax cost: 15% — saving ₹6.84 lakh vs. domestic rate. DTAA saves ₹68.4 lakh annually.
Case Study 02 · Transfer Pricing
PharmaCo India sells APIs to its German Parent at Below-Market Price
Transfer Pricing · TNMM Method · Section 92 IT Act
1
The Facts
PharmaCo India (wholly owned by PharmaCo GmbH, Germany) manufactures Active Pharmaceutical Ingredients (APIs) in Hyderabad and sells 100% of its production to the German parent at ₹500/unit. Independent API manufacturers sell comparable APIs to unrelated parties at ₹800/unit.
2
The Transfer Pricing Risk
By selling at ₹500 instead of ₹800, PharmaCo India underreports ₹300/unit of income. On 10 lakh units/year, this represents ₹30 crore in potentially underreported income — which reduces India's tax base and shifts profits to Germany.
3
TPO Scrutiny & Adjustment
The Transfer Pricing Officer (TPO) using CUP method finds ₹800/unit as ALP. TP Adjustment = (₹800 − ₹500) × 10 lakh = ₹30 crore added to income. At 30% tax rate, additional tax = ₹9 crore. Plus interest (Sec 234B) and penalty (100%–300% of tax avoided under Sec 270A).
4
Safe Harbour Alternative
PharmaCo India qualifies for Safe Harbour Rules (Rule 10TD) if its net operating margin is at least 8.5% on international transactions (for contract manufacturers). If margins are above the safe harbour threshold, no TP adjustment would be made — simplifying compliance.
Lesson Always price inter-company transactions at arm's length. Maintain contemporaneous TP documentation. Consider filing an APA with CBDT for pricing certainty. The bilateral APA between India and Germany would also provide protection from double taxation on the adjustment.
Case Study 03 · Permanent Establishment
UK Consulting Firm Sends Employees to India for 200 Days
Service PE · India-UK DTAA · Article 5
1
The Facts
ConsultCo Ltd (London) wins a ₹50 crore IT consulting contract with an Indian bank. It sends 10 employees to India for 200 days to deliver the project at the client's Mumbai office. ConsultCo has no office, bank account, or registration in India.
2
Is There a PE?
Under the India-UK DTAA, a Service PE arises if employees of the foreign enterprise furnish services in India for more than 90 days in any 12-month period. ConsultCo's employees spend 200 days in India → Service PE is triggered.
3
Tax Consequence
ConsultCo must attribute profits to the Indian PE — typically calculated as a proportion of overall contract profits attributable to Indian operations. The PE's profits are taxable at the applicable rate in India (currently 40% for foreign companies + surcharge). ConsultCo must also register under GST if it provides taxable services in India.
4
Planning Strategy
Could ConsultCo have stayed below 90 days? Potentially — but post-BEPS Action 7 anti-fragmentation rules prevent artificial splitting of a single project across time. A better strategy: set up an Indian subsidiary to execute the contract (separate entity, not a PE) — though this has its own TP considerations.
Outcome Service PE established. Profits attributable to Indian PE taxed in India at 40%+. ConsultCo can claim a tax credit in the UK for taxes paid in India under the India-UK DTAA to avoid double taxation. Lesson: Always assess PE risk before sending employees abroad for extended periods.
Case Study 04 · Pillar Two / GloBE Rules
MegaCorp's Irish Subsidiary Pays 7% ETR — GloBE Top-Up Tax Applies
OECD Pillar Two · IIR · GloBE · 2024 onward
1
The Facts
MegaCorp Inc. (headquartered in the USA) has a subsidiary in Ireland that holds valuable IP. The Irish subsidiary earns €500 million of profit annually, taxed at an effective rate of 7% (Irish corporate rate: 12.5%, but after IP deductions). MegaCorp's total revenue exceeds €10 billion — well above the €750 million GloBE threshold.
2
GloBE ETR Calculation for Ireland
GloBE Income: €500 million
Covered Taxes paid: €35 million (7% ETR)
Substance Exclusion: 5% × payroll (€10M) + 5% × tangible assets (€5M) = €0.75M
Excess Profit: €500M − €0.75M = €499.25M
Top-Up Tax %: 15% − 7% = 8%
Top-Up Tax = 8% × €499.25M ≈ €39.9 Million
3
Who Collects the Top-Up Tax?
If Ireland enacts a QDMTT: Ireland collects €39.9M in additional domestic tax, keeping the revenue in Ireland.
If Ireland has no QDMTT: The US parent applies the IIR and pays the top-up tax in the USA — the revenue flows to Washington instead of Dublin.
4
Business Impact
MegaCorp's effective global tax rate on Irish profits rises from 7% to effectively ~15%. The IP holding structure in Ireland no longer provides the same tax benefit — driving companies to reconsider where IP is held, and encouraging genuine substance in low-tax jurisdictions.
Outcome Pillar Two raises the minimum tax to 15% on €499M of profit — additional tax ≈ €39.9M annually. The Irish QDMTT (enacted since 2024) keeps this revenue in Ireland. This is precisely the intended outcome: eliminating the incentive for profit-shifting to low-tax jurisdictions through paper arrangements without genuine economic substance.
Case Study 05 · Individual Taxation · NRI
An NRI in UAE Sells Indian Shares — Capital Gains Tax?
India-UAE DTAA · Capital Gains · FEMA · NRI Taxation
1
The Facts
Rahul is an Indian national living and working in Dubai (UAE) for 5 years. He is a Non-Resident Indian (NRI). He sells listed Indian shares on the NSE, making a long-term capital gain (LTCG) of ₹25 lakhs. UAE has no income tax on individuals.

The Tax Issue
Under Indian IT Act Section 112A, LTCG on listed shares exceeding ₹1 lakh is taxable at 10% (+ surcharge/cess) in India. As a non-resident, Rahul's India-source income is taxable in India. UAE has no tax on capital gains, so there's no double taxation concern in UAE. Can the India-UAE DTAA help?

DTAA Analysis
The India-UAE DTAA assigns taxing rights on capital gains from shares in an Indian company to India (as the source country). UAE being a nil-tax country, there's no relief available from UAE side. Rahul cannot use the DTAA to escape Indian tax here — India retains full taxing rights on gains from Indian shares.

Tax Calculation
LTCG = ₹25 lakhs
Exemption: First ₹1 lakh exempt
Taxable LTCG: ₹24 lakhs
Tax @ 10%: ₹2.4 lakhs
Health & Education Cess @ 4%: ₹9,600
Total Tax Payable in India: ₹2,49,600
Outcome Rahul pays ₹2.49 lakh in India. No tax in UAE (no income tax there). No double taxation. The DTAA doesn't help eliminate Indian tax here — it merely confirms India's right to tax. Lesson: Being an NRI in a nil-tax country does not eliminate Indian-source income tax — it only eliminates UAE tax.

11. International Tax Compliance Checklist

A practical checklist for Indian companies and MNCs operating cross-border. Use this before each financial year-end.

For Indian Companies Making Payments Abroad

  • Collect TRC and Form 10F from all foreign payees before making cross-border payments
  • Check applicable DTAA treaty rate vs. domestic rate; apply the lower of the two
  • Deduct WHT under Section 195 at the correct rate; deposit by 7th of next month
  • File TDS return in Form 27Q quarterly
  • Issue Form 16A (TDS certificate) to foreign payees within 15 days of due date
  • Obtain a Chartered Accountant certificate (Form 15CB) for all remittances exceeding ₹5 lakh in a financial year
  • File Form 15CA online before making the remittance
  • Check FEMA compliance for capital account transactions

For MNCs with Transfer Pricing Obligations

  • Prepare contemporaneous TP documentation (Master File + Local File) before filing tax return
  • File Form 3CEB (TP Report certified by CA) for international transactions > ₹1 crore
  • File CbCR (Form 3CEAD) if group revenue ≥ ₹5,500 crore; file Form 3CEAC (notification) for Indian constituents
  • Review inter-company agreements — ensure they reflect actual functions, assets, and risks (FAR analysis)
  • Benchmark inter-company transactions using TNMM/CUP/RPM; maintain benchmark comparables set
  • Consider filing Advance Pricing Agreement (APA) for recurring high-value inter-company transactions
  • Monitor safe harbour rule thresholds (Rule 10TD) to simplify compliance where possible

For MNCs Subject to BEPS / Pillar Two

  • Assess GloBE applicability — is consolidated group revenue ≥ €750 million?
  • Compute jurisdiction-level ETR for each country of operation; identify low-ETR jurisdictions
  • Prepare GloBE Information Return (GIR) for jurisdictions that have enacted Pillar Two rules
  • Check transitional CbCR safe harbour eligibility to reduce compliance burden for 2024–2026
  • Review existing tax incentive structures (IP boxes, holiday regimes) for continued viability post-Pillar Two
  • Monitor India's QDMTT legislative progress — be ready to comply once enacted
  • Ensure FATCA/CRS compliance — Foreign Financial Institutions must identify and report relevant accounts

12. Penalties & Enforcement Risks

International tax non-compliance carries severe penalties in India and globally. Here are the key risks to understand.

100%–300%
Transfer Pricing Penalty (Section 270A)
Penalty for under-reporting income due to TP adjustments. 200%–300% for misreporting. Plus 12%–18% p.a. interest on under-paid tax.
2% p.m.
WHT Default Interest (Section 201)
For failure to deduct or deposit WHT on time — interest at 1–1.5% per month plus potential prosecution under Section 276B.
₹5 Lakh
CbCR / Master File Penalty
Failure to file Country-by-Country Report (Form 3CEAD) or Master File (Form 3CEAA). ₹5,000/day for continued default.
300%
Black Money Act Penalty
On undisclosed foreign assets: 300% of the undisclosed asset value plus ₹10 lakh flat penalty + possible 3–10 years imprisonment.
30%
FATCA Non-Compliance WHT
Foreign Financial Institutions non-compliant with FATCA face 30% withholding on US-sourced payments — a severe commercial sanction.
₹2 Lakh
Form 3CEB Non-Filing Penalty
Penalty for failure to furnish Transfer Pricing Report (Form 3CEB) is 2% of the value of each international transaction. Can be very large.

13. Frequently Asked Questions

No. Section 90(4) of the Income Tax Act makes it mandatory for a non-resident to furnish a TRC from their home country's tax authority to claim DTAA benefits. Additionally, CBDT requires Form 10F self-declaration. Without these documents, the payer must deduct WHT at the higher domestic rate. Note: the Supreme Court has ruled that mere absence of TRC doesn't deny treaty benefits if the non-resident can otherwise prove residency — but this is exceptional and litigation-prone.
Residence-based taxation: The country of residence taxes its residents on their worldwide income regardless of where it's earned (India, USA, UK use this). Source-based taxation: The country where income arises taxes that income regardless of where the recipient lives (the "source" country). Most countries use a combination of both — taxing their residents on worldwide income AND taxing non-residents on income sourced within their borders. DTAAs allocate and limit these overlapping rights.
Treaty shopping occurs when a resident of a third country (Country C) routes investments through a resident of Country A to take advantage of a favourable A-B treaty. For example, a US company sets up a paper entity in Mauritius solely to benefit from the India-Mauritius DTAA. Post-BEPS, the MLI's Principal Purpose Test (PPT) allows tax authorities to deny treaty benefits if one of the principal purposes of a transaction was to obtain treaty advantages. India's GAAR also applies to such arrangements.
No. An NRI (Non-Resident Indian) is taxable in India only on income that is received in India, accrues in India, or is deemed to accrue in India under Section 5(2) of the IT Act. Foreign income earned and received outside India is not taxable in India for NRIs. However, once a person qualifies as "Ordinarily Resident" under Section 6, global income becomes taxable. RNOR (Resident but Not Ordinarily Resident) is an intermediate status providing some protection for foreign income.
An APA is an agreement between a taxpayer and the CBDT (and potentially a foreign tax authority in bilateral APAs) that pre-agrees the TP methodology for specific inter-company transactions for up to 5 years, with a rollback of 4 years possible. APAs provide certainty, eliminate audit risk, and reduce litigation. They are highly recommended for companies with large, recurring, complex inter-company transactions (e.g., manufacturing captives, IP licensing, shared services). The CBDT charges an application fee of ₹10–20 lakh. Processing typically takes 1–3 years.
If you're an Indian company that is part of a multinational group with global revenue ≥ €750 million, and you operate in countries that have already enacted GloBE rules (EU, UK, Japan, South Korea, etc.), you need to provide data for GloBE computations to your group's parent entity. Even if India hasn't enacted its own GloBE rules yet, your data flows into your group's global top-up tax calculation. As India's QDMTT enactment approaches, large Indian MNCs will need to compute their own ETR in India and potentially pay top-up taxes.
India's Equalization Levy is a 6% tax on digital advertising payments to non-resident companies (introduced in 2016) and a 2% levy on e-commerce supply of goods/services by non-resident e-commerce operators (introduced in 2020). The 2% e-commerce levy was repealed effective August 2024 following US pressure and the OECD Pillar One negotiations. The 6% digital advertising levy remains. This is separate from income tax and is a "digital tax" India imposes even without a PE.
