Understanding Your GST/HST Obligations as a Canadian Business

If you run a business in Canada, you should know about your GST/HST obligations. GST stands for Goods and Services Tax, and HST means Harmonized Sales Tax. These are indirect taxes that apply to most goods and services sold here.
What is GST/HST?
The Goods and Services Tax (GST) charges 5% on many goods and services across Canada. Some provinces mix this with their own sales tax, making the Harmonized Sales Tax (HST). The HST rate is usually higher than just GST alone.
Who Needs to Register?
You must register for a GST/HST account with the Canada Revenue Agency (CRA) if your business makes more than $30,000 a year from taxable supplies. This lets you collect tax from your customers for the government. CRA GST/HST Registration
Reporting Periods
Your reporting period shows how often you file your GST/HST returns:
- Annual if your business earns less than $1.5 million.
- Quarterly if it makes between $1.5 million and $6 million.
- Monthly if it earns over $6 million. Knowing this helps you file on time.
Filing Deadlines
Deadlines depend on your reporting period:
- Annual filers must file by June 15 of the next year.
- Quarterly filers file one month after each quarter ends.
- Monthly filers file by the end of the month after their reporting period. Missed deadlines can lead to penalties or interest.
Input Tax Credits (ITCs)
You can claim input tax credits for any GST/HST paid on things you buy for your business. So, if you pay GST or HST on supplies or services, you can get some of that money back when filing—this lowers your costs.
Common Errors to Avoid
Watch out for these mistakes when filing:
- Not keeping clear records of sales and purchases.
- Mixing up exempt supplies with zero-rated supplies.
- Forgetting to claim available ITCs.
- Missing filing deadlines causing fines. Good records make audits easier and reduce errors.
Importance of Accurate Record-Keeping
Keeping good records helps you follow business tax obligations in Canada. It also makes it easier to match sales and purchases when you prepare reports or financial statements.
By keeping up with GST/HST compliance, Canadian businesses can handle their duties smoothly and avoid issues with CRA checks or fines.

Registering for a GST/HST Number and Determining Your Reporting Period
Registering for GST/HST
If your business in Canada makes over $30,000 in revenue during four calendar quarters, you have to register for a GST/HST number with the Canada Revenue Agency (CRA). This lets you collect and pay the Goods and Services Tax (GST) or Harmonized Sales Tax (HST) on your sales.
Even if your income is less than $30,000, you can still sign up voluntarily. Doing this lets you claim back input tax credits (ITCs) on things you buy for your business.

- Fill in info about your business type and what you do.
- Get your special GST number that links to your account. Register soon so you don’t get in trouble with the law. Remember, after you register, you must file returns regularly—even if you didn’t sell anything that period.
Determining Your Reporting Period
The CRA sets your reporting periods based on how much tax you owe yearly. This decides how often you send GST/HST returns:
- $1,500,000 or less: Annually
- More than $1,500,000: Quarterly
- Large businesses: Monthly Most small businesses send returns every year or every three months. Big businesses with lots of sales send them every month.
When payments are due depends on this:
- Monthly: Due one month after period ends.
- Quarterly: Due one month after each quarter.
- Annually: Due three months after year end. Picking the right reporting period helps keep your cash flow steady and paperwork easy. You can check or change it through CRA My Business Account or call CRA directly.
Keep good records no matter what. Track all sales and buys carefully so your returns match reality.
Knowing how to do GST registration and choosing the right reporting period helps Canadian businesses handle taxes easier and follow the rules well.
Collecting and Calculating Your GST/HST
Knowing how to Collect GST/HST from Customers
You need to charge GST or HST on most taxable goods and services sold in Canada. Here’s the lowdown:
- GST Collection Process: When you sell a product or service that’s taxable, add the right GST or HST rate for your province.
- Business Revenue Threshold: If your total money made goes over $30,000 in four quarters in a row, you have to register for a GST/HST account and start charging tax.
- Taxable Supplies: Most things you sell are taxable unless they are zero-rated (taxed at 0%) or exempt supplies.
- Invoicing Requirements: Your bills must clearly show how much GST/HST you charged. Also, include your business number (BN) from the CRA. Charging the correct tax keeps your records straight when you file your returns.
Calculating GST/HST Owed: Input Tax Credits (ITCs) and Net Tax

To know how much GST/HST you owe, subtract your ITCs from the total tax collected.
- Calculate Total Collected Tax: Add up all the GST/HST you charged customers during the reporting time.
- Input Tax Credits (ITCs): These let you get back tax paid on business stuff like office supplies, equipment, rent, utilities, and professional fees.
- To claim ITCs:
- Keep good receipts showing taxes paid.
- Make sure expenses are tied to business activities.
- Net Tax Calculation: Take away total ITCs from collected taxes. What’s left is what you pay CRA or get back if ITCs are more than what you charged. It’s super important to keep clear sales invoices and purchase receipts to match these numbers right every time.
Follow these steps — charge the right tax from customers and claim legit input tax credits — so your returns match CRA rules. Gondaliya CPA can help businesses file their GST/HST returns on time and reduce audit risks by doing careful calculations and record keeping.
