If you’re a business owner in Canada, dealing with GST/HST is part of your financial responsibility. Whether you're just starting out or have been operating for years, understanding and complying with the Goods and Services Tax (GST) and Harmonized Sales Tax (HST) requirements is essential. That’s where a professional Calgary tax accountant can make a big difference.

Filing GST/HST isn’t just about submitting a form—it requires accurate bookkeeping, timely reporting, and a clear understanding of CRA guidelines. Working with a qualified Calgary accountant ensures that your business stays compliant while also avoiding penalties and interest charges.

Let’s explore how tax accountants in Calgary help businesses like yours manage GST/HST filing and stay in line with Canadian tax laws.

Understanding GST/HST: A quick overview

GST is a federal tax applied to most goods and services sold in Canada. In provinces that harmonise their sales tax with the federal government (like Ontario or Nova Scotia), the combined tax is called HST.

In Alberta, businesses only deal with GST, which is currently set at 5%. If your business earns more than $30,000 in gross revenue in a year, you are required to register for a GST number and begin charging GST on your invoices.

Failing to do so—or doing it incorrectly—can lead to serious issues with the Canada Revenue Agency (CRA). That’s why many Calgary businesses rely on a trusted Calgary tax accountant to handle their GST filing

Registering for GST/HST

The first step in GST compliance is registration. A Calgary accountant helps you determine:

• Whether you're required to register

• When and how to register with the CRA
  
  

• How to correctly apply GST to your services or products
  
  

For new business owners, this process can be confusing. A tax accountant ensures you’re set up properly right from the start.

Setting up your accounting system

Once you’re registered, tracking your GST becomes an ongoing task. That means you need a reliable system for recording GST collected on sales and GST paid on business expenses.

Your Calgary tax accountant will:

• Help you implement bookkeeping software
  
  

• Create GST codes and categories for easy tracking

• Train your staff or bookkeeper on accurate data entry

• Monitor records to ensure they are CRA-compliant

This kind of setup is essential for preparing accurate GST returns and reducing your risk of audit.

Filing GST/HST returns

Depending on your business’s annual revenue, you may be required to file monthly, quarterly, or annually. Missing a deadline or submitting an incorrect return can result in penalties, interest charges, or even CRA reviews.

With a professional Calgary accountant handling your GST returns, you benefit from:

• Timely reminders and submission of return

• Accurate calculations of GST collected vs. GST paid

• Review of all data before submission to avoid errors

• Filing through CRA’s online portal for quick processing
  
  

They make sure your returns are submitted on time, every time—saving you from last-minute panic or missed deadlines.

Claiming input tax credits (ITCs)

One of the advantages of being GST-registered is the ability to claim input tax credits. These are refunds for the GST you pay on business-related purchases. But claiming them requires accurate documentation and a clear understanding of eligible expenses.

A Calgary tax accountant helps you:

• Identify which expenses qualify for ITCs

• Ensure proper receipts and invoices are kept on file

• Calculate your ITCs correctly for each reporting period

• Avoid over-claiming or under-claiming, which can trigger audits

This ensures you’re getting the full benefit of your GST registration without risking non-compliance.

Staying audit-ready and compliant

The CRA conducts random and targeted audits to ensure businesses are complying with GST laws. If you are ever selected, having a professional Calgary accountant on your side is a major asset.

They will:

• Keep your financial records up to date and organised

• Respond to CRA queries and audit requests on your behalf

• Help resolve discrepancies and reduce the risk of penalties

By working with a qualified tax accountant, you are always prepared—whether or not you’re audited.

Beyond GST: Ongoing tax planning support

GST/HST is just one part of your business's overall tax responsibilities. A Calgary tax accountant can also help you:

• Plan for income taxes and payroll obligations

• Set up quarterly tax instalments

• Analyse your financials for business growth

• Reduce tax liability through smart planning strategies
  

They become your financial partner—helping you avoid problems while maximising your tax savings.
