What is the GST/HST rate in Ontario?

Ontario uses the Harmonized Sales Tax (HST) at a combined rate of 13%. This includes 5% federal GST and 8% provincial portion. HST is collected as a single tax — businesses do not charge GST and PST separately in Ontario.

Which provinces have HST in Canada?

Five provinces use HST: Ontario (13%), New Brunswick (15%), Nova Scotia (15%), Newfoundland and Labrador (15%), and Prince Edward Island (15%). The remaining provinces and territories charge GST separately, with some also charging a provincial sales tax (PST, RST, or QST).

What is the small supplier threshold for GST/HST?

The small supplier threshold is $30,000 in revenue over any 4 consecutive calendar quarters, or $30,000 in a single calendar quarter. If your taxable supplies exceed this amount, you must register for GST/HST within 29 days and begin collecting tax. Below the threshold, registration is voluntary.

What is the Quick Method for GST/HST?

The Quick Method is a simplified accounting option for small businesses with revenue under $400,000. Instead of tracking Input Tax Credits (ITCs), you remit a flat rate of GST collected: 3.6% of taxable supplies for service businesses or 1.8% for goods resellers. This often results in lower GST/HST remittances and simpler bookkeeping.

How to Use This Calculator

Tab "Add/Remove Tax"

Enter an amount, select your province or territory, and choose whether to add tax or remove tax from a tax-inclusive amount. The calculator shows the GST, HST, PST/QST/RST breakdown and total amount. Useful for invoicing, pricing, and expense verification.

Tab "Small Business Threshold"

Enter your annual revenue and business type to check if you exceed the $30,000 small supplier threshold.

Tab "GST/HST Credit"

Enter your adjusted family net income, filing status, and number of children under 19. The calculator estimates your annual GST/HST credit and quarterly payment amount, showing the clawback calculation if your income exceeds the threshold.

The Formulas

Adding tax:
Tax = Amount × (GST rate + PST rate) or Amount × HST rate
Total = Amount + Tax

Removing tax (tax-inclusive):
Before tax = Total ÷ (1 + combined rate)
Tax = Total - Before tax

2025 GST/HST rates by province:
Alberta, Yukon, NWT, Nunavut: GST 5%

Small supplier threshold:
Registration required if revenue > $30,000 in any 4 consecutive quarters or single quarter

Quick Method remittance:
Service businesses: Revenue × 3.6%
Goods/retail: Revenue × 1.8%

GST/HST credit (2024-25):
Base: Single $519, Married $680, + $179/child
Clawback: 5% × max(0, Family net income - threshold)
Annual credit = max(0, Base + child credits - clawback)

Example

Sarah — Freelance Designer in Toronto, Invoice $5,000

Sarah invoices a client $5,000 for design work. She is in Ontario (HST 13%) and her annual revenue is $48,000.

Amount before tax$5,000.00

HST (13%)$650.00

Total invoice$5,650.00

Registration required?Yes — $48K exceeds $30K threshold

Quick Method remittance (3.6%)$1,728 vs $2,400 GST collected

Sarah must be registered for GST/HST since her $48,000 annual revenue exceeds the $30,000 threshold. Using the Quick Method, she remits only $1,728 instead of collecting $2,400 in HST and tracking ITCs — saving $672 and simplifying her bookkeeping.

Frequently Asked Questions

What is the difference between GST and HST?▼

GST (Goods and Services Tax) is the 5% federal sales tax applied across all of Canada. HST (Harmonized Sales Tax) combines the federal GST with a provincial portion into a single tax rate — 13% in Ontario, 15% in New Brunswick, Nova Scotia, Newfoundland & Labrador, and PEI. In HST provinces, businesses collect and remit one combined tax instead of separate federal and provincial taxes.

Do I need to register for GST/HST?▼

You must register if your taxable revenue exceeds $30,000 over any 4 consecutive calendar quarters, or $30,000 in a single quarter. This is called the small supplier threshold. Once exceeded, you have 29 days to register and must begin collecting GST/HST. Below the threshold, registration is voluntary but may be beneficial if you want to claim Input Tax Credits on business expenses.

How does the Quick Method work?▼

The Quick Method is a simplified way to calculate GST/HST remittance for small businesses (revenue under $400,000). Instead of tracking Input Tax Credits (ITCs) on every expense, you remit a flat percentage of your taxable supplies including GST/HST collected: 3.6% for service businesses or 1.8% for goods resellers. You still charge the full GST/HST rate to customers. The difference between what you collect and what you remit is additional income. This method reduces bookkeeping but you cannot claim ITCs on most purchases.

Who qualifies for the GST/HST credit?▼

The GST/HST credit is available to Canadian residents aged 19 or older (or those with a spouse/common-law partner or child). It is based on your adjusted family net income from the previous year's tax return. For the 2024-25 payment year, the maximum credit is $519 for singles, $680 for couples, plus $179 per child under 19. The credit is reduced by 5% of income above the applicable threshold. You must file a tax return to receive the credit — it is paid automatically in quarterly installments.

Is PST included in HST?▼

Only in HST provinces (Ontario, NB, NS, NL, PEI), where the provincial tax is merged with federal GST into a single HST rate. In British Columbia (7% PST), Saskatchewan (6% PST), and Manitoba (7% RST), provincial sales tax is collected separately and is not part of the federal GST system. Quebec's QST (9.975%) is also separate, administered by Revenu Quebec. PST/RST/QST paid on business expenses generally cannot be claimed as Input Tax Credits on your GST/HST return.
