VAT vs GST: What's the Difference? Complete 2025 Guide

1. Introduction to Indirect Taxes

Value Added Tax (VAT) and Goods and Services Tax (GST) are both forms of indirect consumption taxes levied on the sale of goods and services. While they share similar objectives—generating government revenue and ensuring tax compliance—they differ in structure, implementation, and administration.

Understanding these differences is crucial for:

Business Owners: Proper tax compliance and pricing strategies
Consumers: Understanding what you're paying for
International Traders: Cross-border tax implications
Investors: Tax considerations in different markets

Quick Comparison

VAT:	Used in 160+ countries including UK, EU, China
GST:	Used in 40+ countries including Canada, Australia, India

2. What is VAT (Value Added Tax)?

VAT is a multi-stage tax levied on the value added at each stage of production and distribution. Introduced in France in 1954, it has become the world's most common form of consumption tax.

How VAT Works

VAT operates on a credit-invoice method:

Output Tax: Tax charged on sales to customers
Input Tax: Tax paid on purchases from suppliers
Net VAT: Output Tax minus Input Tax = Amount owed to government

Example: VAT Chain

Manufacturer:

Buys raw materials for $100 + $20 VAT (20%) = $120
Sells to wholesaler for $200 + $40 VAT = $240
Pays government: $40 - $20 = $20

Wholesaler:

Buys for $200 + $40 VAT = $240
Sells to retailer for $300 + $60 VAT = $360
Pays government: $60 - $40 = $20

Retailer:

Buys for $300 + $60 VAT = $360
Sells to consumer for $400 + $80 VAT = $480
Pays government: $80 - $60 = $20

Total VAT collected: $20 + $20 + $20 = $60 (15% of final price)

VAT Rates Around the World

Country	Standard Rate	Reduced Rates
UK	20%	5%, 0%
Germany	19%	7%
France	20%	10%, 5.5%, 2.1%
Italy	22%	10%, 5%, 4%
China	13%	9%, 6%

VAT Registration Thresholds

Businesses must register for VAT when their taxable turnover exceeds certain thresholds:

UK: £90,000 per year
Germany: €22,000 per year
France: €85,800 (goods) / €34,400 (services)
EU Average: €10,000 - €100,000

3. What is GST (Goods and Services Tax)?

GST is a comprehensive, multi-stage, destination-based tax levied on every value addition. While similar to VAT in principle, GST typically has a more unified structure and often replaces multiple indirect taxes.

How GST Works

GST operates on the same credit-invoice method as VAT but often with additional features:

Comprehensive Coverage: Replaces multiple taxes (sales tax, service tax, excise duty)
Destination-Based: Tax collected where goods/services are consumed
Input Tax Credit: Similar to VAT's input tax deduction
Digital Compliance: Often requires electronic filing and invoicing

Types of GST (India Example)

India's GST system has three components:

CGST (Central GST)

Collected by central government on intra-state supplies

SGST (State GST)

Collected by state government on intra-state supplies

IGST (Integrated GST)

Collected by central government on inter-state supplies and imports

GST Rates by Country

Country	Standard Rate	Special Features
Canada	5% (Federal)	+ Provincial sales tax
Australia	10%	Broad-based, few exemptions
India	5%, 12%, 18%, 28%	Multiple slabs
Singapore	9%	Simple, single rate
New Zealand	15%	Minimal exemptions

4. Key Differences Between VAT and GST

Aspect	VAT	GST
Full Name	Value Added Tax	Goods and Services Tax
Tax Base	Value addition at each stage	Supply of goods and services
Structure	Often coexists with other taxes	Usually replaces multiple taxes
Rates	Typically 1-3 rates	Can have multiple slabs
Compliance	Varies by country	Often digital/online
Prevalence	160+ countries	40+ countries

Naming Differences

The choice between VAT and GST is often historical and political rather than technical:

VAT: Emphasizes the "value added" concept, popular in Europe
GST: Broader term covering both goods and services, popular in Commonwealth countries
Functionally: Both achieve the same goal of taxing consumption

💡 Important Note

Some countries use both terms! For example, Australia calls it GST but it functions like VAT. The terminology matters less than understanding how the tax works in your specific jurisdiction.

5. Country-Specific Examples

UK VAT System

The UK's VAT system is one of the most established:

Standard Rate: 20% on most goods and services
Reduced Rate: 5% on domestic fuel, children's car seats
Zero Rate: 0% on food, books, children's clothes
Exempt: Insurance, education, health services
Registration: Required if turnover exceeds £90,000

Canada GST/HST System

Canada uses a dual system:

Federal GST: 5% nationwide
Provincial Sales Tax (PST): Varies by province (0-10%)
Harmonized Sales Tax (HST): Combined federal + provincial in some provinces (13-15%)
Registration: Required if revenue exceeds CAD $30,000

Australia GST System

Australia's GST is known for its simplicity:

Single Rate: 10% on most goods and services
GST-Free: Basic food, health, education, exports
Input Tax Credits: Businesses can claim back GST paid
Registration: Required if turnover exceeds AUD $75,000

India GST System

India's GST is the most complex, with multiple rates:

0%: Essential items (grains, milk)
5%: Household necessities
12%: Processed foods
18%: Most goods and services (standard)
28%: Luxury items, sin goods
Registration: Required if turnover exceeds INR 40 lakhs (goods) or 20 lakhs (services)

6. How to Calculate Each

VAT Calculation Formula

To Add VAT:

VAT Amount = Price × (VAT Rate / 100)

Total Price = Price + VAT Amount

Example (20% VAT):

Price: £100
VAT: £100 × 0.20 = £20
Total: £100 + £20 = £120

To Remove VAT:

Price Without VAT = Total Price / (1 + VAT Rate)

VAT Amount = Total Price - Price Without VAT

Example (20% VAT):

Total Price: £120
Price Without VAT: £120 / 1.20 = £100
VAT Amount: £120 - £100 = £20

GST Calculation Formula

GST calculation is identical to VAT:

Example (10% GST - Australia):

Price: AUD $100
GST: $100 × 0.10 = $10
Total: $100 + $10 = $110

7. Compliance and Registration

When to Register

Both VAT and GST require registration when your business turnover exceeds certain thresholds. Key considerations:

Mandatory Registration: When turnover exceeds threshold
Voluntary Registration: Can register below threshold to reclaim input tax
Penalties: Late registration results in fines and back-taxes
Monitoring: Track turnover monthly to avoid missing registration deadline

Filing Requirements

VAT Returns (UK Example)

Quarterly filing (every 3 months)
Online submission via Making Tax Digital
Payment due within 1 month and 7 days
Records must be kept for 6 years

GST Returns (India Example)

Monthly filing (GSTR-1, GSTR-3B)
Annual return (GSTR-9)
Electronic filing mandatory
E-invoicing for large businesses

8. Which System is Better?

Neither system is inherently "better"—effectiveness depends on implementation and local context:

VAT Advantages

Proven track record (70+ years)
Widely understood internationally
Established compliance frameworks
Easier cross-border trade (EU VAT system)

GST Advantages

Can replace multiple taxes (simplification)
Often more comprehensive coverage
Modern digital compliance systems
Clearer terminology for consumers
