For most sellers, e-commerce accounting is an exciting new platform for vast marketing opportunities. Thanks to technology, businesses can now bid manual financial data management goodbye. Data storage, access, and processing are now faster and more flexible than ever.
However, e-commerce accounting brings new challenges too. Difficulty in handling financial data is still present. If you use the wrong tool or use the right one incorrectly, you're at risk of financial trouble. If there's something you should be putting a close eye on, it's tax compliance.
Regardless of having a physical store or not, taxes are compulsory. Moreover, the variety makes it challenging: each state or country has different tax laws. Since e-commerce allows you to expand target selling locations, you'll have to pay meticulous attention to the tax requirements and comply.
It is a challenging aspect of e-commerce, but you can overcome it with a clear understanding of tax considerations. This article focuses on tax compliance and harmonized sales tax (HST). So if you're selling to Canada, this is the perfect time to learn about it.

E-Commerce Accounting and Tax Compliance
The tax rules made a drastic turn since the South Dakota v. Wayfair, Inc. in 2018. The law allows states to require e-commerce sellers for sales tax collection and remittance.
In addition, states implemented a nexus based on the level of sales or transaction. Nexus links a state and a business that involves sales tax registration, collection, and remittance.
The Challenge
Since tax collection and remittance are no longer dependent on physical footprint, e-commerce sellers have to catch up with the ever-changing state policies. Unfortunately, the laws per state differ, so e-commerce businesses have a hard time adjusting.
In addition to this overwhelming shift, the pandemic also pushed sellers to rely more on digital presence to keep the business running. As a result, businesses reevaluate and implement operational changes to keep the opportunities coming.
Canadian Tax System: An Overview
Canadian sales taxes are primarily divided into the federal sales tax (GST) and the provincial sales tax (PST). This is the traditional tax system, and many Canadian provinces today still use it.
However, due to the differences in the sales tax rates of each province, the HST was introduced. GST and PST rates are combined into one standard rate (HST) across the Canadian regions.

What is the Harmonized Sales Tax?
Some new to HST might be searching for "Harmonized sales tax meaning” to get a gist of what it's all about. Here's what you need to know.
A consumption tax
HST is a retail consumption/consumer tax imposed at the point of sale. The Canada Revenue Agency collects it and remits the remaining amount to the involved provinces. A consumption tax is levied on a purchase and comes in different forms (e.g., tariffs, excise, and sales taxes).
It doesn’t cover all of Canada.
As mentioned earlier, not all provinces in Canada collect HST. Many of them still use the traditional system, and only five provinces currently follow the harmonized sales tax act. These provinces are (including their total tax rate):
- New Brunswick: 15% (updated as of July 2016)
- Newfoundland and Labrador: 15% (updated as of July 2016)
- Nova Scotia: 15% (since 1997)
- Ontario: 13% (since 2010)
- Prince Edward Island: (15% since 2013)
How does it work?
Depending on what your province collects, you must register your business for a GST/HST account. Once you do, you'll be given effective dates (monthly, quarterly, and annually) to start sales tax collection and report.
An important note: You only need to register if you no longer qualify as a small supplier. For example, you haven't sold more than $30,000 worth of products and services in the past four quarters.
Rates vary depending on where you sell goods and services.
It's not easy for Canadian businesses to sell to another territory. You must follow the rate from where your business resides, but you also have to distribute the charge per the rate of the shipping destination.
For example, you have an Ontario business (harmonized sales tax in Ontario is 13%), and you ship to Manitoba. In that case, you must charge 5% GST from Ontario and 7% from Manitoba as part of its retail sales tax requirements.
Meanwhile, if the destination is outside Canada, none of the three taxes are applicable for transaction charges.
