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

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.
