Navigating taxes as a small business owner can be overwhelming, especially when it comes to the Harmonized Sales Tax (HST). Whether you’re just starting your venture or looking to stay compliant, understanding what is HST in Ontario? is crucial for running a successful business.

If you’ve found yourself searching for clear advice on HST filing for small businesses in Peterborough, you’re in the right place. This comprehensive guide will demystify everything from HST registration to audits — helping you avoid pitfalls and take control of your tax obligations.

What is HST in Ontario?

The Harmonized Sales Tax (HST) in Ontario is a combination of the federal Goods and Services Tax (GST) and the provincial sales tax (PST), resulting in a single tax rate of 13%. This streamlined system simplifies the process for businesses that collect and remit sales taxes.

Breakdown of HST in Ontario:

5% Federal GST
8% Ontario PST Total: 13% HST

HST applies to most goods and services sold in Ontario. As a business owner, understanding sales tax in Ontario is fundamental to remaining compliant and avoiding costly penalties.

Who Needs to Register for HST?

Understanding HST registration rules helps determine when and if you need to collect HST.

You are required to register for HST if:

You make more than $30,000 in taxable sales annually (small supplier threshold).
You operate as a sole proprietor, partnership, corporation, or non-profit with taxable goods/services.
You want to claim Input Tax Credits (ITCs) on business expenses (even if under $30,000).

You can voluntarily register for HST before reaching $30,000 to take advantage of ITCs sooner.

For step-by-step guidance through the HST registration process, contact Hunt Solutions Group’s tax specialists.

The Process of HST Registration

If your business meets the criteria, registering for HST is relatively straightforward.

How to register:

Apply online via CRA’s Business Registration Online (BRO) service.
Register by phone, mail, or in-person with the CRA.
Receive your HST number, which must appear on all invoices.

Key documentation required:

Business number (BN)
Business structure details (sole proprietorship, corporation, etc.)
Business activity description
Estimated sales figures

HST registration isn’t just a legal obligation — it can also unlock Input Tax Credit opportunities that improve cash flow. Hunt Solutions Group can guide you through optimal timing and filing structures.

Understanding Input Tax Credits (ITCs)

A major benefit of registering for HST is the ability to claim Input Tax Credits (ITCs). ITCs allow businesses to recover the HST paid on business-related purchases and expenses.

Eligible ITC claims include:

Office supplies
Rent and utilities
Business equipment
Advertising and marketing services
Professional services (like accountants or consultants)

How to Collect and Charge HST Correctly

Once registered, you are legally obligated to charge HST on taxable goods and services.

Key guidelines:

Include your HST number on all invoices.
Clearly separate the base price and HST amount.
Indicate the 13% rate explicitly.

For businesses providing both taxable and exempt services, consult Hunt Solutions Group to ensure accurate compliance.

HST Remittance: How and When to Pay

HST remittance is the process of sending the collected HST to the CRA. Your remittance schedule depends on your revenue.

Filing frequency:

Annual: Revenues under $1.5M (optional quarterly)
Quarterly: Revenues $1.5M - $6M
Monthly: Revenues over $6M

How to remit HST:

Online through CRA’s My Business Account
Through your financial institution
By mail using CRA remittance forms

Accurate and timely HST remittance avoids penalties and ensures business compliance.

Frequent late filings
Large ITC claims
Inconsistencies between income tax and HST filings

Preparation tips:
