FAQ

What types of GST regimes are there in Canada?

Canada runs a dual-structure GST system, so the final GST on a transaction depends on both federal and local (provincial) rules. For example, a taxable supply in Quebec attracts two rates: federal GST and Quebec Sales Tax. A supplier with sales both inside and outside Quebec files two returns: a GST/HST return for sales elsewhere in Canada, and a QST return for Quebec sales.

How complicated is the GST registration process in Canada?

It depends on your situation, mainly whether you’re a local business operating in Canada or a non-resident with no establishment there. In most cases registration is transparent, fast and online. We have extensive experience with GST registration and compliance in Canada for both.

Is GST imposed on accommodation services supplied via a digital platform in Singapore?

GST and/or PST usually applies when a digital marketplace facilitator enables the supply of accommodation services between providers and customers in the country. Confirming taxability requires reviewing the terms between platform and provider, and the platform operator’s main activity, which we assess for you.

Does Singapore have different GST registration requirements for resident and non-resident digital service providers?

It depends on whether the supplier has a physical presence in the country. Singapore’s tax authority runs a simplified GST registration and filing framework for non-resident digital service providers.

Is the GST return filing process unified across Canada’s provinces and territories?

No. Canada’s dual GST system means federal and provincial rates combine to set the rate on a supply. Some provinces use a Harmonized Sales Tax (HST) unifying federal GST and local PST, while others run PST independently. Registration requirements and filing procedures differ between GST/HST and PST returns, and between provinces that handle PST separately.

What are the penalties for non-compliance with GST in Canada, India and Singapore?

They vary by jurisdiction. In Canada, penalties and interest often result from late GST registration and filing, and provincial rules differ by place-of-supply. In India, late-filing penalties can start at ₹100 per day. In Singapore, non-resident digital service providers under the simplified regime face the same penalty and compliance rules as domestic GST-registered persons.

What is the GST threshold for non-resident e-commerce suppliers in Singapore?

Registration for non-resident suppliers and e-marketplace operators rests on two cumulative conditions: global turnover, and B2C supplies of remote services and imported low-value goods where the place of supply is Singapore.

We operate a digital platform expanding into Singapore. Must we register for GST, and collect and remit on behalf of underlying suppliers?

Yes. A GST-registered non-resident digital platform operator must collect and remit GST for third-party non-resident digital service providers supplying through its platform.

We supply SaaS worldwide and recently expanded into Canada. Do we register once and file one return, or are there separate provincial requirements?

It depends where your Canadian customers are. If they’re in provinces outside the unified GST/HST regime, you’ll also need to register for provincial sales tax, for example in British Columbia or Manitoba.
