GST/HST Exempt vs Zero-Rated: Key Differences
The distinction between exempt and zero-rated supplies is the single most consequential GST/HST classification decision a Canadian business makes — because it determines whether you can recover the HST you pay on your expenses. This guide explains the difference, covers out-of-scope transactions, walks through industry examples and shows the dollar impact of getting it wrong.
The Core Difference: ITCs Are the Entire Story
Both exempt and zero-rated supplies result in no HST being charged to your customer. From the customer's perspective, the outcome looks identical — they pay no tax. But from the business owner's perspective, the difference is enormous because it determines whether you can claim Input Tax Credits (ITCs) to recover the 13% HST you pay on your business expenses in Ontario.
If your supply is zero-rated, you charge 0% HST on your sales but you remain fully entitled to claim ITCs on all related business purchases. You recover every dollar of HST you spend on rent, supplies, equipment, software, professional fees and vehicle expenses. If your supply is exempt, you charge no HST on your sales and you cannot claim ITCs on the expenses related to those exempt supplies. The HST you pay on your business expenses becomes a permanent cost — it stays buried in your expenses and never comes back.
For a business spending $120,000 per year on HST-taxable expenses in Ontario, the ITC recovery is worth $15,600 per year (13% of $120,000). A zero-rated business recovers that $15,600 every year through its GST/HST return. An exempt business absorbs that $15,600 as an additional operating cost. Over five years, the classification difference represents $78,000 in permanently lost tax recovery for an exempt business.
The Three GST/HST Supply Categories — Plus Out of Scope
Zero-Rated (0%)
HST applies at 0%. You do not charge HST to your customer, but your business is fully in the HST system. You can claim ITCs on all related business expenses. CRA effectively refunds you the HST you pay on your inputs.
This is the most favourable category for a business because you recover all input HST while charging nothing to customers.
Exempt
HST does not apply. You do not charge HST to your customer and you cannot claim ITCs on related business expenses. The HST you pay on your inputs is a permanent cost absorbed by your business.
This is the least favourable category from a cash-flow perspective because HST paid on expenses is never recovered.
Out of Scope
The transaction is completely outside the GST/HST system. It is not a taxable supply, not an exempt supply and not a zero-rated supply. These are transactions that do not involve the provision of goods or services for GST/HST purposes.
Examples: salary and wages, dividends, bank transfers, loan repayments, shareholder loan transactions.
Taxable Supplies (the fourth category): Most goods and services in Canada are taxable at the full HST rate (13% in Ontario, 15% in Atlantic provinces). Taxable supplies are not covered in detail in this guide because the classification question arises only when a supply is not taxable at the standard rate. For taxable supplies, you charge HST and claim ITCs — the straightforward case.
Master Comparison: Taxable vs Zero-Rated vs Exempt vs Out of Scope
| Category | HST Charged on Sale? | ITCs on Related Purchases? | Reported on GST/HST Return? | Must Register for HST? |
|---|---|---|---|---|
| Taxable (standard rate) | Yes — 13% in Ontario | Yes — full recovery | Yes — Line 101 (sales) and Line 106/108 (ITCs) | Mandatory at $30,000 revenue |
| Zero-Rated (0%) | No — 0% rate | Yes — full recovery | Yes — Line 101 (sales at 0%) and Line 106/108 (ITCs) | Mandatory at $30,000 revenue (recommended voluntarily) |
| Exempt | No | No — ITCs generally not claimable | No — exempt revenue not reported on Line 101 | Not required (but see mixed-supply rules below) |
| Out of Scope | No — not a supply | N/A — outside HST system | No | N/A |
Common Zero-Rated Supplies in Canada
Zero-rated supplies are listed in Schedule VI of the Excise Tax Act. The following are the most common categories that Ontario businesses encounter.
| Zero-Rated Supply | HST Charged | ITCs Claimable | Key Notes |
|---|---|---|---|
| Basic groceries (milk, bread, fresh produce, raw meat, eggs) | 0% | Yes | Must be unprocessed or minimally processed. Heated, portioned or ready-to-eat food is taxable at 13%. |
| Prescription drugs | 0% | Yes | Must have a Drug Identification Number (DIN). OTC drugs with DIN may be zero-rated. NHP with NPN is taxable. |
| Certain medical devices (hearing aids, artificial teeth, wheelchairs, pacemakers) | 0% | Yes | Listed in Schedule VI Part II. Cosmetic devices are taxable. |
| Feminine hygiene products | 0% | Yes | Zero-rated since July 1, 2015. |
| Exports of goods and services | 0% | Yes | Most goods shipped outside Canada and services provided to non-resident clients are zero-rated. Documentation required. |

Common Exempt Supplies in Canada
Exempt supplies are listed in Schedule V of the Excise Tax Act. The following are the most common categories that Ontario businesses encounter.
| Exempt Supply | HST Charged | ITCs Claimable | Key Notes |
|---|---|---|---|
| Residential rent (one month or more) | No | No | Long-term residential rental is exempt. Short-term accommodation (under 30 days) is taxable. |
| Most health, dental and medical services | No | No | Services performed by licensed physicians, dentists, optometrists, chiropractors, physiotherapists for medical reasons. Cosmetic procedures are taxable. |
| Child care services | No | No | Care and supervision for children 14 and under, less than 24 hours per day. |
| Educational services | No | No | Vocational courses leading to a certificate/diploma, tutoring following school curriculum. Private tutoring not following curriculum may be taxable. |

| Most charity and public institution supplies | No | No (but PSB rebate may apply) | Public service bodies may claim a partial rebate instead of ITCs. |
| Music lessons | No | No | Provided to individuals. Group lessons through a non-profit may be treated differently. |
| Legal aid services | No | No | Services provided under a legal aid plan. |
The Dollar Impact: What Misclassification Actually Costs
The financial consequence of incorrect classification is not theoretical. The following worked examples show the exact dollar impact for Ontario businesses.
Scenario 1: Grocery Store — Misclassifying Zero-Rated as Exempt
A Scarborough grocery store sells $800,000 per year in basic groceries (zero-rated) and spends $200,000 on HST-taxable business expenses (rent, equipment, packaging, utilities). The store's bookkeeper codes all sales as "exempt" in QuickBooks instead of "zero-rated."
Correct treatment: Zero-rated sales of $800,000 reported on Line 101. ITCs of $26,000 (13% of $200,000) claimed on Line 108. CRA refund of $26,000.
Incorrect treatment: Exempt sales not reported. No ITCs claimed. $26,000 in recoverable HST permanently lost.
Annual cost of misclassification: $26,000 per year in lost ITC recoveryScenario 2: Dental Practice — Claiming ITCs on Exempt Services
A North York dental practice provides exempt dental services and generates $600,000 in revenue. The practice spends $150,000 on taxable expenses (rent, dental supplies, equipment, insurance). The bookkeeper codes all purchases as "taxable" and claims ITCs of $19,500 on the GST/HST return.
Correct treatment: Dental services are exempt. No ITCs claimable on expenses related to exempt services. The $19,500 in HST paid on expenses is a permanent cost.
CRA audit result: CRA reverses the $19,500 in ITCs and assesses interest at 8% per year on the amount owing from the filing date.
CRA assessment: $19,500 reversal + $1,560 interest (one year) = $21,060Scenario 3: IT Exporter — Zero-Rated Exports With Full ITC Recovery
A Vaughan IT consulting company provides software development services to a US-based client. Revenue is $500,000 (zero-rated export). The company spends $100,000 on HST-taxable expenses in Ontario (office rent, hardware, internet, professional fees).
Correct treatment: Export services reported as zero-rated on Line 101. ITCs of $13,000 (13% of $100,000) claimed. CRA issues a refund of $13,000 because the company collected $0 in HST but paid $13,000 in HST on inputs.
Annual ITC refund: $13,000 — the business receives more from CRA than it remitsMixed-Supply Rules — When Your Business Provides Both Taxable and Exempt
Many Ontario businesses provide a combination of taxable (or zero-rated) and exempt supplies. A healthcare clinic that provides exempt medical services and taxable cosmetic procedures, a financial advisor who provides exempt investment management and taxable financial planning, or a non-profit that provides both exempt educational services and taxable event catering — all face the mixed-supply ITC allocation problem.
When you make both taxable and exempt supplies, you cannot claim ITCs on 100% of your expenses. You can only claim ITCs on the portion of expenses that relate to your taxable (including zero-rated) supplies. CRA accepts two methods for allocating ITCs in mixed-supply situations.
| Method | How It Works | Best For |
|---|---|---|
| Direct allocation | Identify each expense as directly related to either taxable or exempt supplies. Claim ITCs only on the taxable-supply expenses. For shared expenses (rent, utilities), allocate based on a reasonable method (square footage, revenue ratio, time spent). | Businesses where taxable and exempt activities are clearly separated (separate departments, floors, staff) |
| Pro-rata allocation | Calculate the percentage of total revenue that is taxable (including zero-rated). Apply that percentage to all shared expenses to determine the ITC-eligible portion. | Businesses where taxable and exempt activities are intermingled and direct allocation is impractical |
CRA Audit Trigger — Overstated ITCs on Mixed Supplies: CRA actively audits businesses that provide both taxable and exempt supplies and claim 100% of their ITCs. If you provide any exempt supplies, CRA expects to see an ITC allocation methodology in your records. Not having a documented allocation method is itself an audit trigger. We prepare ITC allocation schedules for every mixed-supply client as part of our GST/HST filing engagement.

Out-of-Scope Transactions — Completely Outside the HST System
Out-of-scope transactions are not supplies of goods or services for GST/HST purposes. They are not taxable, not exempt and not zero-rated — they simply do not exist within the HST framework. These transactions must be coded separately in your accounting software to prevent them from appearing on your GST/HST return.
| Transaction | Why It Is Out of Scope |
|---|---|
| Salary, wages and employee benefits | Employment is not a supply of goods or services under the Excise Tax Act |
| Dividends paid to shareholders | A distribution of profits, not a supply |
| Shareholder loan advances and repayments | Financial transaction between related parties, not a supply |
| Bank account transfers between your own accounts | Internal movement of funds, not a supply |
| Loan principal repayments to a bank | Repayment of debt, not a supply (interest on loans is an exempt financial service) |
| Capital contributions by shareholders | Equity investment, not a supply |
| Goodwill in a business acquisition | Treated separately under section 167 elections |
Bookkeeping Impact: In QuickBooks Online and Xero, out-of-scope transactions must use the "Out of Scope" tax code. If coded as "Exempt" or "No Tax," they may appear on the GST/HST return in the wrong section and distort your filing. Payroll transactions are the most commonly miscoded — ensure all salary expense accounts use the Out of Scope tax code, not Exempt.
Setting Up GST/HST Codes Correctly in QuickBooks Online and Xero
Correct GST/HST classification starts at the bookkeeping software level. If your default tax codes are wrong on products, services and expense accounts, every transaction inherits the wrong classification — and your GST/HST return will be incorrect from day one.
| Setup Action | QuickBooks Online | Xero |
|---|---|---|
| Set default tax code on each product/service | Products and Services → Edit → Sales Tax Category (Taxable, Zero-rated, Exempt) | Products and Services → Edit → Tax Rate (GST on Income, Zero Rated, Exempt) |
| Set default tax code on expense accounts | Chart of Accounts → Edit each account → Default Tax Code | Chart of Accounts → Edit → Tax Rate on Purchases |
| Set payroll accounts to Out of Scope | Salary expense accounts → Tax Code: Out of Scope | Wages account → No Tax (purchases) |
| Set customer default tax codes | Customer → Edit → Tax exempt (for zero-rated export customers) | Contact → Tax settings → Applicable rate |
| Set bank rules with correct tax codes | Banking → Rules → Assign tax code per recurring vendor | Bank Rules → Assign tax rate per recurring transaction |
Gondaliya CPA Bookkeeping Setup: For every new client, we configure QuickBooks Online or Xero with the correct GST/HST tax codes for their industry from day one. Zero-rated products get the Zero-Rated code. Exempt services get the Exempt code. Payroll and shareholder transactions get Out of Scope. Bank rules are set per vendor. This prevents classification errors from entering the system in the first place. Bookkeeping Services →
CRA Audit Triggers Related to Exempt vs Zero-Rated Misclassification
CRA's GST/HST audit teams specifically look for classification errors because they represent some of the highest-value adjustments. The following are the most common audit triggers related to exempt vs zero-rated misclassification.
| Audit Trigger | What CRA Looks For | Typical Assessment |
|---|---|---|
| Healthcare practice claiming ITCs on exempt services | Dental, medical or optometry practices claiming ITCs without a mixed-supply allocation | Full ITC reversal + 8% interest + potential gross negligence penalty (50% of the ITC amount) |
| Grocery/food business with incorrect food classification | Heated, portioned or ready-to-eat items coded as zero-rated instead of taxable | HST assessed on misclassified sales + interest |
| Residential landlord claiming ITCs | Landlord with long-term residential tenants claiming ITCs on maintenance, repairs and utilities | Full ITC reversal + interest |
| Insurance/financial services claiming ITCs | Insurance broker or financial advisor claiming ITCs on all expenses without allocation | ITC reversal on exempt-supply portion + interest |
| Export zero-rating without documentation | Business claiming zero-rated export status without proof of export (bill of lading, proof of non-resident status, contract) | 13% HST assessed on all "exported" sales retroactively + interest |
