What is simplified GST/HST registration and who can use it?
It is the sales-tax registration route built for non-resident businesses selling digital products or services to Canadian consumers, and for the platforms that facilitate those sales. It is lighter to operate than full registration: less to administer, a narrower set of obligations, and a process designed for a business with no establishment in Canada. The trade is input tax recovery, of which it gives none. Eligibility is therefore the easy half of the question. Whether the route suits the business depends on what that business spends in Canada.
Should I use simplified registration or register the normal way?
Model it rather than default to the lighter option. Simplified registration is easier to operate and gives no input tax recovery, so for a business with Canadian costs it is the wrong trade: the tax on hosting, contractors, warehousing or event spend stays with the business. Full registration costs more to run and opens that recovery. The decision is a modelling exercise against your actual cost base and customer mix, not a preference about paperwork, and it is awkward to revisit once the route has been taken.
Can I use simplified registration if I sell to Canadian businesses too?
The route is built around supplies to Canadian consumers. Where customers are registered businesses the analysis differs, because a registered customer accounts for the tax differently and the supplier position changes with it. A mixed customer base is where the simple answer stops being simple: the split between consumers and registered businesses, and how reliably you can evidence it, drives both the route and the return. Establish the mix from the sales data before choosing, rather than from an assumption about who buys the product.
Does my marketplace have to register if the sellers already have?
Platform operators are within these rules on their own account. Where a platform facilitates supplies of digital products or services to Canadian consumers, the rules can treat the platform as making the supply, which puts the registration and the collection obligation on the platform rather than on the seller. Two registered parties both collecting on the same supply is a real outcome and it surfaces as tax charged twice. Reach one conclusion with your sellers, write it into the terms, and report consistently with it.
Can I switch from simplified to full registration later on?
Changing route is not a setting to be toggled. It is a fresh registration decision with consequences for the periods either side of it, for the tax already collected and reported, and for what can be recovered on Canadian costs. That is why the choice deserves the modelling at the outset. If the business expects Canadian expenditure to grow, whether staff, premises or an event programme, that expectation belongs in the original calculation rather than in a later change of mind.
We sell only a few digital subscriptions in Canada, does this apply?
Volume is part of the registration test, so a small trade can sit outside it, but the test looks at your Canadian sales rather than your global business, and a product that sells quietly for a long time can cross it without anyone looking. Two things are worth doing: establish where you stand against the test on your own sales data, and set a point at which somebody checks it again. The obligation is decided by the facts, so it can arrive with no change in how the business operates.
How would a foreign tax authority know I am resident there?
Mostly from information you or your bank already provided. Account-opening forms ask you to self-certify tax residence, and that certification is reported between authorities under the Common Reporting Standard or, for US accounts, under the FATCA framework. Beyond that: employer and payroll filings, property registries, immigration records and the tax filings of anyone who paid you. The realistic planning assumption is that the data arrives. See FATCA and information reporting.
What happens if I have not filed for several years?
Missed years are handled as one package, not one at a time, because the route chosen for the first year determines the relief available for the rest. Each country has a disclosure or relief programme with its own conditions, and entering the right one — before the authority contacts you — is usually what keeps penalties down. Filing quietly outside a programme forfeits that protection. See catching up on missed returns.
