A Quick HST Guide for Small Business Owners in Ontario


Navigating taxes can be one of the most challenging aspects of running a business. One of the most common and essential taxes that businesses in Ontario deal with is the Harmonized Sales Tax (HST). But what exactly is HST, and how does it impact your business operations?

Whether you’ve just started your business or are looking to streamline your tax process, understanding HST is key to avoiding penalties and maximizing tax savings. From registration to filing, and even claiming Input Tax Credits (ITCs), there’s a lot to know. But don’t worry—this guide is designed to break it all down in simple terms, so you can focus on what matters most—growing your business.

What is HST?

Harmonized Sales Tax (HST) is a consumption tax that combines both the federal Goods and Services Tax (GST) and the provincial sales tax (PST) into a single tax. The purpose of HST is to simplify the taxation process by applying one standard rate across a variety of goods and services in Ontario.

How HST Works
  • Taxable Goods and Services: HST applies to most goods and services sold or provided in Ontario, including physical products, digital goods, professional services, and even some rental arrangements.
  • Collection and Payment: Businesses collect HST from their customers at the point of sale, and then remit it to the Canada Revenue Agency (CRA).
  • Tax Filing: Businesses must regularly file HST returns with the CRA, detailing the amount of HST collected from customers and the amount of HST paid on business expenses. The difference must be paid to or refunded by the CRA.

The Registration Threshold
  • If your business’s annual taxable sales exceed $30,000, you are legally required to register for HST with the CRA.
  • This threshold applies to businesses in Ontario, and it includes all sales of goods and services, excluding sales of used goods.
Voluntary Registration
  • If your business’s taxable sales are below $30,000, you can still voluntarily register for HST. Voluntary registration allows you to claim Input Tax Credits (ITCs) on eligible expenses, which can help reduce your overall tax burden.
Who Should Register?
  • New businesses should plan for HST registration if they anticipate reaching the $30,000 threshold.
  • Sole proprietors, partnerships, and corporations in Ontario are all subject to the same rules when it comes to registering for HST.

Understanding HST Rates in Ontario, Canada

In Ontario, Canada, the standard HST rate is 13%, consisting of the 5% federal GST and 8% provincial sales tax (PST). Understanding how this rate applies to your products and services is vital for accurate pricing and tax compliance.

The HST Rate Breakdown
  • Standard Rate: Most goods and services are subject to the full 13% rate.
  • Zero-Rated Goods and Services: Certain goods and services are taxed at a 0% rate, meaning no HST is charged. Examples include basic groceries, prescription drugs, and medical devices.
  • Exempt Goods and Services: Some goods and services are exempt from HST altogether, such as health care services, educational services, and certain financial services.
Impact on Pricing
  • As a business owner, it’s crucial to know which of your products or services are subject to the full 13% HST rate, and which are either zero-rated or exempt. This knowledge allows you to set accurate pricing and avoid overcharging your customers.

What Are Input Tax Credits (ITCs)?

Input Tax Credits (ITCs) allow businesses to recover the HST they pay on expenses related to their business activities. By claiming ITCs, businesses can reduce their overall tax burden and ensure that they’re only paying tax on the value they add to goods and services.

What Can Be Claimed as an ITC?
  • Eligible Business Expenses: ITCs can be claimed on various business expenses, such as office supplies, rent, utilities, and business-related travel.
  • Capital Costs: ITCs can also be claimed on capital items like computers, vehicles, and equipment used in the course of business operations.
How to Claim ITCs
  • When filing HST returns, businesses must keep accurate records of all HST paid on eligible expenses. The total amount of ITCs claimed is subtracted from the HST collected on sales, resulting in the amount to remit to the CRA or a refund if ITCs exceed HST collected.

How to File HST Returns

Filing HST returns is an essential part of complying with Ontario’s tax laws. Here’s a general overview of the filing process:

Filing Frequency
  • Annual Filing: If your business earns less than $1.5 million in annual taxable supplies, you’ll generally file your HST return once a year.
  • Quarterly Filing: If your business earns between $1.5 million and $6 million in taxable supplies, you’ll file quarterly.
  • Monthly Filing: Businesses with more than $6 million in taxable supplies must file their HST returns on a monthly basis.
Filing Steps
  1. Gather Your Records: Collect all invoices, receipts, and documentation that show the HST you’ve collected from customers and the HST you’ve paid on business expenses.
  2. Complete the HST Return: Using CRA’s online portal or paper forms, complete your HST return, including the amount of HST collected and ITCs you are claiming.
  3. Submit the Return: Submit your return to the CRA and remit any balance owed or request a refund if applicable.
Tips for Accurate Filing
  • Maintain organized records throughout the year to avoid scrambling at tax time.
  • Double-check your math when calculating HST collected versus ITCs claimed.

Common HST Mistakes to Avoid

While managing HST can seem straightforward, small business owners often make common mistakes that can lead to penalties or missed tax-saving opportunities. Here are some mistakes to avoid:

  1. Failing to Register on Time: If your taxable sales exceed $30,000, registering late can result in fines and interest charges.
  2. Incorrectly Applying HST Rates: Misapplying the HST rate to exempt or zero-rated items can lead to costly errors.
  3. Not Claiming Eligible ITCs: Businesses often miss out on potential savings by not claiming ITCs for eligible expenses.
  4. Late Filing: Not filing your HST return on time can lead to late fees and interest on unpaid amounts.
  5. Incomplete Records: Inadequate or incomplete records can make it difficult to file an accurate return, increasing the risk of errors.
