GST/HST on Mandatory Catering Service Charges in Ontario, BC and Alberta
How CRA treats mandatory catering service charges for GST/HST in Ontario, British Columbia and Alberta, plus voluntary gratuities and compliant invoices.
What to take away
- CRA treats mandatory service charges as part of the taxable sale, so GST/HST applies to them.
- Voluntary tips that customers choose and employees keep are generally not taxable.
- Ontario charges 13% HST, BC applies 5% GST plus PST where the food or drink is taxable, and Alberta charges 5% GST only.
- A compliant invoice shows the caterer's GST/HST number, the rate applied, and the tax amount separately.
- Failing to collect on mandatory service charges can lead to CRA assessing the uncollected tax plus interest and penalties.
The CRA rule that pulls service charges into the tax base
Canada Revenue Agency administers GST/HST under the Excise Tax Act. Its rule is simple: a mandatory service charge is part of the consideration for a taxable catering supply.
The customer has no choice about paying it, so it cannot be a voluntary gratuity. CRA's guidance on GST/HST rates and when to charge them confirms the tax applies to the total amount paid for the taxable supply. That total includes food, beverage, room rental for a served event, and any mandatory service percentage you add. A caterer who splits these on an invoice does not change the tax base. The same logic covers delivery, set-up, and cleaning fees if they are part of the catering price.
Mandatory service charge vs voluntary gratuity
A service charge is mandatory when the contract adds a fixed percentage, the menu states it, or the event order requires it. A voluntary gratuity is different. The customer decides the amount, and the server or bartender keeps it directly. CRA looks at who controls the amount and who controls distribution.
CRA's working distinction: a charge is taxable if it is mandatory, set by the caterer, or distributed by the caterer. A charge is not taxable if the customer chooses the amount and the employee keeps it.
If you pool tips and share them according to a house formula, CRA may still see a service charge. A line on the invoice that says 'gratuity' does not decide the tax treatment. The facts about control do. For a quote, separate the taxable service charge from any optional tip line. A clear catering quote template separates taxable charges from optional gratuities before the contract is signed.
How GST/HST applies in Ontario, BC, and Alberta
Rates differ because provinces choose whether to combine with the federal GST or keep a separate sales tax. CRA's place of supply rules decide which province's rate applies to a catered meal. Generally the rate follows where the meal is served, not where the client's office is.

Tax treatment of mandatory service charges
- Ontario
- Included in the taxable total
- British Columbia
- Included where the underlying sale is taxable
- Alberta
- Included in the taxable total
Ontario's 13% HST already combines federal and provincial parts. BC does not use HST. It adds PST on most prepared food and drink sold by caterers. Alberta has no provincial sales tax, so only the 5% federal part applies.
A caterer working in one province for a client in another must use the rate for the province where the meal is served. This follows the place of supply rules, not the client's billing address. Do not apply an HST rate in Alberta or a PST exemption in BC unless the item is explicitly exempt. The same tax treatment applies to a Banquet Beverage Package when a mandatory service charge on drinks appears on the invoice.
What a compliant invoice and record file carries
Your invoice is the label for tax purposes. A compliant invoice carries your nine-digit GST/HST registration number, the rate applied to each taxable supply, and the tax amount shown separately. Keep copies of event contracts, signed change orders, tip distribution records, and remittance forms. CRA can ask for records that show why a charge was not taxed. A stock control checklist links inventory withdrawals to taxable meals and supports your input tax credit claims.
Keep these records for six years from the end of the tax year. CRA may ask for the contract, the invoice, and proof that any tip was voluntary. A missing record for a mandatory charge will not protect you from assessment.
What happens if you skip collection
A caterer who fails to collect GST/HST on mandatory service charges can be assessed the uncollected tax plus interest and penalties. CRA can also deny input tax credits for related purchases if the records do not support the taxable supply. Repeat failures can lead to a compliance audit that covers all years open for assessment.
The assessment is not limited to the one event. CRA can go back through multiple years if it finds a pattern. Penalties for failure to collect are not deductible as business expenses. A Plated Dinner vs Buffet comparison may hide service charges in a per-guest total, but CRA still assesses the uncollected tax when the charge is mandatory. This consequence does not change with menu style.
