Filing your Harmonized Sales Tax (HST) return in Ontario is an essential responsibility for businesses registered for HST. Properly submitting your HST return ensures compliance with tax laws, helps avoid penalties, and keeps your business in good standing with the Canada Revenue Agency (CRA). Whether you're a new business owner or looking to streamline your process, this comprehensive guide will walk you through each step of how to file your HST return in Ontario efficiently and accurately.
Understanding HST and Its Importance in Ontario
The Harmonized Sales Tax (HST) in Ontario combines the federal Goods and Services Tax (GST) of 5% with the provincial sales tax of 8%, resulting in a total rate of 13%. Businesses that make taxable sales, leases, or other supplies in Ontario are required to register for HST if their revenues exceed the threshold set by CRA.
Filing your HST return is not just a legal obligation; it is also a way to report your collected taxes and claim input tax credits (ITCs) for the HST paid on eligible business expenses. Accurate reporting and timely filing help you maintain compliance and optimize your cash flow.
Who Needs to File an HST Return in Ontario?
- Businesses registered for HST with CRA, regardless of size
- Businesses that have registered voluntarily for HST
- Businesses that make taxable supplies in Ontario and exceed the registration threshold
If your business is registered for HST, you are required to file periodic returns, which can be monthly, quarterly, or annually, depending on your total taxable supplies and your choice upon registration.
Preparing to File Your HST Return
Before filing, gather all necessary documentation and records to ensure accuracy. Here’s what you need to prepare:
- Sales invoices and records of taxable sales made in Ontario
- Purchase invoices and receipts showing HST paid on business expenses (input tax credits)
- Previous HST returns and payments made or refunds received
- Details of any adjustments or corrections from previous filings
Proper record keeping is essential. Maintain organized records for at least six years, as CRA may request to review your documentation.
Steps to File Your HST Return in Ontario
1. Access the Canada Revenue Agency My Business Account Portal
The easiest way to file your HST return is through CRA’s online portal, My Business Account. If you haven't registered yet, you can do so on the CRA website. Online filing offers convenience, faster processing, and secure access to your tax information.
2. Log In to Your CRA Account
Use your CRA user ID and password or Sign-In Partner login credentials to access your account. If you do not have an account, set one up following CRA’s registration procedures.
3. Select the Appropriate Reporting Period
Identify the correct period for which you are filing. This could be monthly, quarterly, or annual, depending on your registration choice or CRA’s requirements.
4. Fill Out the HST Return Form
The online form will prompt you to enter:
- Total sales and other revenues subject to HST in Ontario
- Total eligible input tax credits (ITCs) for HST paid on business purchases
- Adjustments or corrections, if any
Ensure all figures are accurate and correspond to your records to avoid discrepancies or audits.
5. Calculate Your Net Tax
The system will automatically compute your net tax payable or refundable based on the provided data. If your collected HST exceeds your ITCs, you owe the difference. Conversely, if your ITCs are higher, you may be eligible for a refund.
6. Submit Your Return
Review all entries carefully before submitting. Once satisfied, submit your HST return electronically through CRA’s portal. You will receive a confirmation receipt. Save or print this receipt for your records.
7. Make Your Payment
If you owe taxes, arrange to make your payment by the deadline, which is typically one month after the reporting period ends. CRA offers multiple payment options:
- Online banking via your financial institution
- CRA’s My Payment service
- Pre-authorized debit
- Mailing a cheque or money order
Ensure your payments are made on time to avoid interest and penalties.
Filing HST Returns Manually (Paper Filing)
While online filing is recommended, you can also submit a paper HST return if necessary. Obtain the appropriate form (GST34 – Goods and Services Tax/Harmonized Sales Tax Return) from CRA or your accountant.
Fill out the form carefully, attach supporting documents if required, and mail it to CRA’s designated address. Remember that manual processing may take longer, so plan accordingly.
Deadlines and Penalties for Late Filing
Timely filing is crucial. The deadline for submitting your HST return depends on your reporting period:
- Monthly filers: within one month after the end of the month
- Quarterly filers: within one month after the end of the quarter
- Annual filers: within three months after the fiscal year-end
Failing to file on time can result in penalties and interest charges. CRA may impose a penalty of 5% of the amount owing, plus 1% for each month overdue, up to a maximum of 12 months.
To avoid penalties, set reminders and ensure your filings are submitted before the deadline.
Tips for Simplifying Your HST Filing Process
- Keep detailed and organized records of all sales and expenses
- Use accounting software compatible with CRA’s system
- Consult a tax professional for complex transactions or uncertainties
- Review previous filings to identify recurring errors or discrepancies
- Set up reminders for upcoming filing deadlines
- Stay updated on any changes in CRA’s filing procedures or tax rates
Understanding Input Tax Credits (ITCs) and How to Claim Them
Input Tax Credits (ITCs) are the amounts of HST paid on eligible business expenses that you can recover when filing your return. Properly claiming ITCs reduces your net tax payable or increases your refund.
To claim ITCs:
- Ensure expenses are related to commercial activities
- Keep supporting documents such as invoices and receipts
- Verify that the supplier is registered for HST
- Report the total eligible ITCs accurately on your return
Incorrect or missing documentation can delay your refund or lead to audits, so meticulous record-keeping is vital.
Common Mistakes to Avoid When Filing HST in Ontario
- Submitting inaccurate figures due to poor record-keeping
- Missing filing deadlines, resulting in penalties
- Failing to claim eligible input tax credits
- Incorrectly calculating the net tax payable
- Not updating CRA with changes in business information
Being attentive to detail and maintaining organized records will help you avoid these common pitfalls and ensure a smooth filing process.
When to Seek Professional Help
If your HST situation involves complex transactions, multiple jurisdictions, or you’re unsure about eligible expenses, consulting a tax professional can be a wise investment. An accountant or a tax advisor can help you:
- Ensure compliance with CRA regulations
- Optimize your input tax credits
- Prepare and review your returns for accuracy
- Handle audits or disputes with CRA
Professional assistance can save you time, reduce errors, and potentially save money by maximizing your credits and deductions.
