Navigating the world of Canadian taxes can be daunting, especially for small business owners. One of the crucial aspects of tax compliance is understanding the Harmonized Sales Tax (HST) and knowing when and how to open an HST account. This comprehensive guide will walk you through every step, providing clear instructions, essential information, and expert tips to ensure you’re fully compliant and ready to manage your HST obligations effectively.

What is HST and Why Do You Need an Account?

HST is a consumption tax in certain provinces of Canada, combining the federal Goods and Services Tax (GST) with a provincial sales tax. It’s collected on most goods and services and remitted to the government. Having an HST account allows you to collect this tax from your customers, claim input tax credits (ITCs) on eligible business expenses, and remit the net amount to the Canada Revenue Agency (CRA).

Key Takeaway: An HST account is essential for businesses that meet specific criteria, allowing them to legally collect HST, claim ITCs, and remit taxes efficiently.

Did you know? As of 2025, HST is applicable in Ontario, Nova Scotia, New Brunswick, Newfoundland and Labrador, and Prince Edward Island. The HST rates vary by province.

Determining If You Need to Register for HST

Not every business needs to register for an HST account. Here are the key factors to consider:

  1. Annual Revenue: You must register for HST if your taxable supplies (revenue from sales of goods and services) exceed $30,000 CAD in a single calendar quarter or over four consecutive calendar quarters. This threshold applies to most businesses, including sole proprietorships, partnerships, and corporations.
  2. Voluntary Registration: Even if you don’t meet the $30,000 threshold, you can voluntarily register for HST. This can be beneficial if you incur significant business expenses and want to claim ITCs to offset the HST you collect.

Important Considerations:

  • Small Supplier Definition: Businesses with taxable supplies below $30,000 are considered “small suppliers.” They are not required to register for HST, but they also cannot collect HST or claim ITCs.
  • Exceptions: Certain types of businesses, such as those providing taxi services, must register for HST regardless of their revenue.
  • Non-Residents: Non-resident businesses operating in Canada that make taxable supplies must generally register for HST, regardless of their revenue.

Actionable Tip: Track your revenue carefully and monitor your taxable supplies to determine when you reach the $30,000 threshold, triggering the mandatory HST registration requirement.

Data Point: In 2024, the CRA reported that over 1.5 million small businesses in Canada voluntarily registered for HST to take advantage of input tax credits. (Source: CRA Statistical Review, 2024)

Step-by-Step Guide to Opening an HST Account

Opening an HST account is a straightforward process. Here’s a step-by-step guide to help you:

Step 1: Gather Required Information

Before you start the registration process, gather the following information:

  • Business Number (BN): You need a Business Number to register for HST. If you don’t have one, you can obtain it through the CRA’s online Business Registration Online (BRO) service or by calling the CRA Business Enquiries line.
  • Business Name and Address: Your legal business name and physical address.
  • Contact Information: Name, phone number, and email address of the business owner or authorized representative.
  • Business Activity: A detailed description of your business activities.
  • Projected Annual Revenue: An estimate of your annual taxable supplies.
  • Fiscal Year-End: The end date of your business’s fiscal year.
  • Date of First Taxable Supply: The date you made or will make your first sale of goods or services subject to HST.

Step 2: Choose a Registration Method

You can register for HST through several methods:

  • Online via Business Registration Online (BRO): This is the fastest and most convenient method. You can access BRO through the CRA website.
  • Through a Representative: If you are hiring a professional, you can complete Form RC59, Business Consent, to authorize a representative (e.g., an accountant) to access your CRA account and register for HST on your behalf.
  • By Mail: Complete Form RC1, Request for a Business Number and Certain Program Accounts, and mail it to your nearest CRA Tax Centre.

Step 3: Complete the Registration Form

Whether you’re registering online or by mail, you’ll need to provide the information gathered in Step 1. Be prepared to answer questions about:

  • Your business structure (sole proprietorship, partnership, corporation)
  • The nature of your business activities
  • Your reporting period (monthly, quarterly, or annual)

Pro Tip: Double-check all information for accuracy before submitting your application. Errors can cause delays or even rejection of your registration.

Step 4: Receive Your HST Account Number

After your registration is processed, you’ll receive an HST account number. This number is an extension of your Business Number and will be in the format: BN + RT0001 (e.g., 123456789RT0001).

Important: Keep your HST account number in a safe place. You’ll need it when you file your HST returns and make payments.

Step 5: Set Up Your Accounting System

Once you have your HST account, it’s essential to set up an accounting system to track the HST you collect and the ITCs you’re eligible to claim. Consider using accounting software like QuickBooks Online, Xero, or Sage, or consult with an accountant to establish a system that meets your specific needs.

Best Practice: Maintain accurate and organized records of all sales, purchases, and HST transactions. This will make filing your HST returns much easier and reduce the risk of errors or audits.

Choosing Your HST Reporting Period

When registering for HST, you’ll need to choose your reporting period:

  • Annual: If your annual taxable supplies are $1.5 million or less, you can choose to file annually.
  • Quarterly: If your annual taxable supplies are more than $1.5 million but not more than $6 million, you must file quarterly.
  • Monthly: If your annual taxable supplies exceed $6 million, you must file monthly.

Strategic Decision: Choosing the right reporting period depends on your cash flow and administrative capacity. Filing annually is simpler but requires a larger lump-sum payment. Filing monthly or quarterly provides more frequent opportunities to claim ITCs and manage your cash flow.

Expert Insight: Most small businesses with taxable supplies below $1.5 million find that filing annually is the most convenient option, as it minimizes administrative burden.

Key Considerations and Best Practices

  • Input Tax Credits (ITCs): ITCs are credits you can claim to recover the HST you paid on eligible business expenses, such as office supplies, equipment, and professional fees. Keep detailed records of all expenses and ensure they are directly related to your commercial activities.
  • Filing Deadlines: Be aware of the filing deadlines for your reporting period. Filing late can result in penalties and interest charges. The annual filing deadline is generally three months after your fiscal year-end.
  • Online Filing: The CRA encourages businesses to file their HST returns electronically. Online filing is faster, more secure, and reduces the risk of errors.
  • Payment Options: You can pay your HST online through the CRA’s My Business Account, through your financial institution, or by mail.
  • Professional Advice: If you’re unsure about any aspect of HST registration or compliance, consult with a qualified accountant or tax advisor. They can provide personalized guidance and help you avoid costly mistakes.

Common Mistakes to Avoid

  • Failing to Register When Required: Not registering for HST when you exceed the $30,000 threshold is a serious compliance issue that can result in penalties and interest.
  • Incorrectly Calculating HST: Make sure you’re calculating HST correctly on your sales and purchases.
  • Claiming Ineligible ITCs: Only claim ITCs for eligible business expenses. Expenses for personal use are not eligible.
  • Missing Filing Deadlines: Keep track of your filing deadlines and submit your returns on time.
  • Poor Record-Keeping: Maintain accurate and organized records of all HST transactions.
