FAQs

What is the difference between GST and VAT?

GST and VAT are functionally identical — both are multi-stage consumption taxes with input tax credits, placing the ultimate burden on end consumers. The terminology differs by country. Countries like Canada, Australia, and India use 'GST'; EU countries use 'VAT.' Some countries use both terms for different parts of a combined tax system.

Do US companies selling software to Australian businesses owe Australian GST?

Yes. Australia requires offshore suppliers of digital products and services (including SaaS, online software, streaming) to register for GST and collect it on sales to Australian consumers exceeding AUD $75,000 annually. For B2B sales, Australian businesses account for GST through the reverse charge mechanism.

What is Input Tax Credit (ITC) in a GST system?

Input Tax Credit allows a registered business to deduct the GST it has paid on business purchases (inputs) from the GST it collects on sales (outputs), remitting only the net difference to the government. This prevents 'cascading' taxation where tax is levied on tax, ensuring the effective rate equals the GST rate only at the final consumer level.

Goods and Services Tax (GST) is a comprehensive consumption tax levied on the supply of most goods and services, operating on the same value-added principle as VAT — collected at each stage of the supply chain with credits for taxes paid on inputs, so the final burden falls on the end consumer. GST is the dominant indirect tax system in many major economies including Canada, Australia, New Zealand, Singapore, and India.

In Canada, GST is a federal tax of 5%, which in most provinces is combined with Provincial Sales Tax (PST) or harmonized into the Harmonized Sales Tax (HST) that ranges from 13–15% depending on province. Quebec has its own parallel QST system. This creates significant compliance complexity for businesses operating across Canadian provinces.

Australia's GST is a flat 10% applied to most goods and services, with key exemptions for food, health, education, and charitable activities. Businesses with annual turnover above AUD $75,000 must register for GST, collect it on taxable supplies, and claim credits for GST paid on business expenses.

India's GST, implemented in 2017, is a dual structure (Central GST + State GST) with multiple rate slabs (0%, 5%, 12%, 18%, 28%) depending on the type of goods or services, creating significant complexity across 29 states and 7 union territories.

For technology companies expanding internationally, GST compliance in each target country is a material operational requirement. Digital services often have specific GST rules — Australia requires offshore digital service providers to register and collect GST on B2C sales exceeding AUD $75,000, similar to EU VAT rules.
