To a customer, an exempt sale and a zero-rated sale look identical: the invoice shows no sales tax either way. To the business issuing that invoice they are opposites, and the gap between them shows up in your bank account every quarter. Which label applies decides whether the GST you paid on your own costs ever comes back.
Key Takeaways
- Zero-rated means taxed at 0 per cent, so credits survive.
- Exempt means outside the system, so the tax you pay is stranded.
- Zero-rated revenue counts toward the $30,000 threshold; exempt revenue does not.
- Businesses that make both must split their credits on a fair and reasonable basis.
- Exporters with no tax to collect are often the ones who most need to register.
The Differences Between Zero-Rated Supplies and Exempt Supplies
Both types of supplies are defined by list, not by principle. Schedule VI of the Excise Tax Act (ETA) holds the list of zero-rated items. Schedule V sets out which supplies are exempt. Nothing lands in either column because it feels essential or unprofitable. Specific supplies are named, and a good or service is on a list or it is not. Everything else is subject to the GST at the ordinary GST rate of 5 per cent, plus the provincial portion in a harmonized province.
| Feature | Taxable | Zero-rated | Exempt |
|---|---|---|---|
| Tax you charge | 5, 13, 14 or 15 per cent | 0 per cent | None |
| Credits on your costs | Yes | Yes | No |
| Counts toward the $30,000 threshold | Yes | Yes | No |
| Where it is defined | Everything not listed | Schedule VI | Schedule V |
That third row is the one owners miss. A zero-rated supply is still a taxable supply, charged at a nil rate, which keeps you in the system with every right that comes with it. An exempt sale is outside the system entirely, so where a sale is exempt you never collect the GST and never claim the GST back.
Zero-Rated Supplies Still Earn You Input Tax Credits
Because you remain a registrant making taxable supplies, every dollar of tax on your rent, software, equipment and professional fees stays recoverable through an input tax credit. Businesses whose sales are mostly zero-rated therefore file returns claiming more than the GST collected on their sales, and they receive money back rather than sending it.
What that is worth. A Mississauga manufacturer ships $800,000 of goods to buyers abroad, all zero-rated, and pays $95,000 for Ontario inputs plus $12,350 of tax on them. It charges customers nothing and can recover the GST in full, all $12,350 of it. The amount of GST it collects is nil, and the amount it reclaims is not. A practice note that costs nothing to act on: businesses in a steady refund position should ask about monthly filing rather than quarterly, because the same refund arriving three times as often is a real cash-flow gain.
Exempt Supplies Strand the Tax You Already Paid
Reverse the position and the arithmetic turns hostile. A landlord renting apartments on twelve-month leases makes only exempt supplies and cannot claim input tax credits on any of it, so the $5,200 of harmonized sales tax on a $40,000 roof replacement in Ontario is a cost of doing business, not a credit. Expenses related to making exempt supplies carry no recovery at all, and the tax on inputs acquired to provide these supplies stays exactly where it lands. Nothing recovers it, and no election fixes it, because you cannot register in respect of exempt activities that sit outside the tax base.
This is why the same building can behave in two completely different ways depending on how it is rented. Our guide to Airbnb and short-term rental tax covers the point where residential property crosses out of the exempt column, and the change-of-use bill that arrives with it.
Examples of Zero-Rated Supplies You Might Be Making
Zero-rated supplies are goods and services the Act keeps inside the tax base at a nil rate. Zero-rated supplies include basic groceries and exports, and these supplies are taxed at 0 per cent rather than left untaxed. Exports of goods are typically zero-rated, and a service supplied to a non-resident may be zero-rated as well. That is why the zero-rated list matters so much to anyone selling from it.
- Basic groceries, which covers most unprepared food and excludes snacks, restaurant meals and carbonated drinks
- Prescription drugs and dispensing services
- Medical and assistive devices, including hearing aids, wheelchairs and artificial limbs
- Most agricultural and fishing products sold in bulk
- Exports of goods shipped out of Canada
- Most services supplied to a non-resident person
- International freight transportation
Zero-rated goods leaving the country need export evidence on file, and exports are the category most likely to catch a service business by surprise. A supply of goods shipped abroad qualifies only where the conditions are met, and they are narrower than they look. Supplies made outside Canada never enter the system, while supplies made in Canada do, so which province, or which country, a sale belongs to is settled by the place of supply rules before you classify anything.
Common Exempt Goods and Services in Canada
Examples of exempt supplies include long-term housing, health care and financial services. Services dominate that list, though a handful of goods appear on it too. The exempt categories are narrow and specific, so read them before you treat any sales as exempt.
- Residential rent where the same individual has continuous occupancy of at least one month
- Sales of previously occupied homes by someone who is not a builder
- Most health, dental and medical services provided by licensed practitioners
- Child care for children 14 and under
- Most educational courses leading to a certificate, diploma or licence
- Financial services, including most lending, insurance and account fees
- Municipal transit and legal aid services
- Many supplies made by charities and public institutions
New housing is the trap inside that list. A previously occupied home sold by an individual is generally exempt, while a newly built one carries the full rate, which is the whole reason the new housing rebate exists. Watch the edges elsewhere too, because an exempt financial service can sit beside a chargeable administration fee, and medical supplies can be zero-rated while the service that fits them is exempt.
Mixed Businesses: When You Charge GST on Some Sales and Not Others
Plenty of businesses make more than one kind of supply. A physiotherapy clinic provides exempt medical treatment, sells zero-rated braces and runs workshops that carry the full rate, all from one location and one lease. Taxable and exempt revenue inside one business is normal, not a red flag.
Section 141.01 of the ETA requires you to allocate inputs to each activity using a method that is fair and reasonable and applied consistently. Rent gets split, equipment gets split, and the credit you claim reflects only the commercial share. Auditors rarely dispute that a split exists; they dispute the method behind it and the absence of any written support for it. In our CRA representation files, the clinics and schools that lose are the ones claiming a round 50 per cent nobody can trace back to floor space, revenue or hours.
Resist the opposite error too. Where a customer buys one thing, splitting the invoice into taxed and untaxed parts does not make it two supplies. The Agency looks at what was actually provided, and an artificial split usually collapses on review. Firms that provide exempt supplies alongside commercial ones should record the exempt classification for each revenue line as it is created, not at year end.
How a GST Exemption Changes Your $30,000 Threshold
Only taxable revenue, including zero-rated supplies, counts toward small supplier status. Services that are taxable count, and so do goods, while exempt supplies cannot be counted at all. So a consultancy earning $600,000 entirely from foreign clients is nowhere near a small supplier, must register, and will still never charge a cent of tax to anyone.
The registration question turns on which supplies of property and services you make. Zero-rated sales are considered taxable supplies for that test, while certain supplies drop out of it. No GST applies to exempt revenue, and the GST paid on the costs behind that revenue is gone for good. Everything else is subject to GST at the applicable rate.
That is the counterintuitive result worth remembering: the business with nothing to collect is often the one with the strongest reason to register, because registration is the only route to recovering the tax on its own costs. Meanwhile a residential landlord earning $600,000 in rent counts none of it, and gains nothing by registering. The mechanics of registering, charging and filing sit in our guide to HST for small business, and smaller mixed businesses should also price out the Quick Method of accounting, which handles the two categories differently.
Zero-Rated and Exempt Supplies: Common Questions
Are exempt and zero-rated the same?
No. Both mean the customer pays no tax, but only zero-rated sales let the seller recover the tax on its own purchases. Exempt sales strand that tax permanently, which makes exempt the more expensive category to operate in.
What is the difference between zero-rated and non-taxable?
Zero-rated sales are taxable supplies charged at a rate of 0 per cent, so they keep you inside the system. Supplies that are simply outside the scope, such as a transaction made entirely outside Canada, never enter it and carry no recovery rights at all.
What does GST exempt mean?
It means the supply appears in Schedule V of the ETA, so no tax applies and no credits may be claimed on the inputs used to make it. Residential rent, most health care and most financial services are the common examples.
What is exempt from GST in Canada?
The common examples of GST exempt supplies in Canada are long-term residential rent, resales of used homes by non-builders, most medical and dental care, child care for children 14 and under, most tuition-style education, financial services and many charitable supplies. The full list sits in Schedule V.
Zero-rated vs exempt: why are zero-rated supplies important?
A zero-rated supply is a taxable supply carried at a nil rate, so it protects your right to recover the tax on every input behind it. Exempt revenue removes that right. For an exporter or a grocer, that single distinction decides whether the business runs a refund position or absorbs a permanent cost.
Do I need a GST number if I only provide exempt services?
No. Exempt revenue never counts toward the $30,000 small supplier threshold, and registering brings no recovery because the credits are unavailable either way. Register only if you start making taxable or zero-rated sales as well.
What records must a business keep to support a zero-rated or exempt supply claim?
Keep the evidence that puts each sale on its list: export documents and shipping records for exports, practitioner licensing for health services, and lease terms for residential rent. Keep your allocation method in writing too. Exempt vs zero-rated is decided on the file, and the burden of proof sits with you.
Can one business have taxable, exempt and zero-rated revenue at once?
Yes, and many do. You charge the correct treatment on each sale and allocate your costs between commercial and exempt activity on a fair and reasonable basis. Document the allocation method when you adopt it, not when an auditor asks.
The Bottom Line
Classification is not a labelling exercise. It decides whether the tax you pay on your own costs comes back.
- Check the schedules before treating a sale as exempt or zero-rated.
- Treat zero-rated revenue as taxable revenue for registration purposes.
- Budget stranded tax into pricing wherever your revenue is exempt.
- Write down your allocation method the day you start making both kinds of supply.
- Revisit the classification whenever your product mix changes.
Most classification disputes we see began as a reasonable assumption that nobody tested against the schedules. If your revenue mix has shifted, or a new product line does not fit neatly into either column, our corporate tax advisory team can map it before the filing does it for you.
