1. What is International Taxation?

International taxation refers to how different countries apply tax rules to cross-border transactions involving individuals, companies, and organizations. It answers questions such as:

  • Who pays tax on international income?
  • Which country gets the tax?
  • How to prevent double taxation?

📋 Key Terms for Students: Cross-border income, tax liability, source jurisdiction, tax residence

2. Key Concepts: Residence vs. Source Rule

Countries use two main rules for taxation:

  • Residence Rule: A country taxes its residents on their worldwide income.
  • Source Rule: A country taxes only the income generated within its borders.

🎓 Quick Tip: Learn how different countries (like India, USA, UK) apply these rules in exams.

3. Understanding Double Taxation

Double taxation happens when the same income is taxed twice:

  • Once in the country where income is earned (source country)
  • Again in the country where the taxpayer resides

Solutions to Avoid Double Taxation:

  • Tax Credit System
  • Tax Exemption System
  • Double Taxation Avoidance Agreements (DTAAs)

📋 Exam Focus: DTAAs are frequently asked in B.Com/M.Com and UGC NET Paper 2 Commerce.

4. The Role of Tax Treaties (DTAAs)

DTAAs (Double Taxation Avoidance Agreements) are signed between countries to prevent unfair taxation. They:

  • Clarify which country taxes what type of income
  • Lower withholding tax rates
  • Promote global investment

📖 For Students: Study the India-USA DTAA or India-Mauritius DTAA to understand how tax savings happen in real life.

5. Introduction to Transfer Pricing

Transfer pricing refers to the pricing of goods/services between associated enterprises in different countries (like a parent company and its foreign subsidiary).

Why It Matters:

  • Prevents profit shifting to low-tax countries
  • Ensures fair taxation of multinational companies

📋 For MBA & M.Com: Important topic in international business taxation modules.

  • Job Opportunities: High demand for international tax experts in MNCs, Big 4 firms, and government
  • Competitive Exams: Topics on DTAAs and global tax rules are now part of UGC NET Commerce and SET exams

7. Practical Example: DTAA in Action

Case:
An Indian freelancer earns $10,000 from US clients.

  • USA (Source Country): Withholds 10% tax = $1,000
  • India (Residence Country): Taxes 30% on global income = $3,000

Thanks to DTAA: India allows a tax credit of $1,000.
So, freelancer pays only $2,000 more in India (not full $3,000).

📋 Learnings: This case is useful for answering real-world application questions in case study-based exams.
