If you run a small business in Nova Scotia, understanding how HST works is an important part of staying organized and meeting your tax obligations. From knowing when you need to register to understanding how much HST to charge and when to file your return, there are several rules business owners need to keep in mind.
For new business owners in particular, HST can seem complicated. The good news is that once you understand the basics and have a reliable bookkeeping system in place, managing HST becomes much easier.
What Is HST?
The Harmonized Sales Tax (HST) combines the federal Goods and Services Tax (GST) with the provincial portion of sales tax. Businesses that are registered for GST/HST generally collect the applicable tax on taxable goods and services and remit it to the Canada Revenue Agency (CRA).
The amount you collect from customers is not business income. It is money collected on behalf of the government, which makes accurate bookkeeping especially important.
When Does a Small Business Need to Register for HST?
Many small businesses do not have to register for GST/HST immediately.
Generally, the CRA considers a business a small supplier if its total taxable revenues, before expenses, are $30,000 or less over the applicable period. Once your business exceeds the small-supplier threshold, you may be required to register for GST/HST.
It is important to monitor your revenue throughout the year rather than waiting until tax season. The timing of when you cross the threshold can affect when you are required to register and begin charging HST.
Some businesses may also choose to register voluntarily before reaching the $30,000 threshold. Whether voluntary registration makes sense depends on your business, customers, expenses, and administrative needs.
How Much HST Should You Charge in Nova Scotia?
The HST rate applicable to a sale depends on several factors, including what you are selling and where the supply is considered to take place.
For a Nova Scotia business, this means you should not automatically assume that every customer or transaction receives the same tax treatment. Businesses selling to customers outside Nova Scotia, providing certain exempt services, or operating across multiple provinces may have additional rules to consider.
Using properly configured accounting and invoicing software can make it much easier to apply and track the appropriate sales tax.
What Are Input Tax Credits?
One of the advantages of being registered for GST/HST is the ability to claim eligible Input Tax Credits, commonly called ITCs.
When your business pays GST/HST on eligible purchases and operating expenses, you may be able to claim some or all of that tax as an Input Tax Credit. This reduces the net amount of GST/HST you have to remit.
For example, a business may pay GST/HST on expenses such as software subscriptions, office supplies, professional services, equipment, or other eligible business purchases.
Keeping receipts and properly categorizing these expenses is essential. Without accurate records, you may miss eligible ITCs or have difficulty supporting a claim if the CRA requests documentation.
How Often Do Businesses File HST Returns?
Your GST/HST filing period is assigned when you register and can vary depending on your circumstances. Businesses may have annual, quarterly, or monthly reporting periods.
Your filing frequency determines how often you need to calculate:
- GST/HST collected on taxable sales
- Eligible Input Tax Credits
- Adjustments that may apply
- The resulting amount owing or refund
It is also important to distinguish between your filing deadline and your payment deadline, as they are not always the same.
Missing a required deadline can result in interest or penalties, so keeping your books current throughout the year can help prevent last-minute problems.
Common HST Bookkeeping Mistakes
HST errors are often caused by relatively simple bookkeeping issues. Business owners may forget to register after crossing the small-supplier threshold, charge the wrong tax rate, incorrectly categorize transactions, miss eligible Input Tax Credits, or treat HST collected as business revenue.
Another common problem is waiting until the end of the year to organize everything.
Regular bookkeeping makes it easier to see how much HST has been collected, identify eligible tax paid on expenses, and understand how much may need to be remitted. It can also help avoid the unpleasant surprise of discovering that money collected for HST has already been spent elsewhere in the business.
Keep Your HST Records Organized
Good record keeping is one of the simplest ways to make HST filing easier.
Invoices, receipts, expenses, sales records, and HST collected should be recorded consistently throughout the year. Your bookkeeping should also clearly separate sales revenue from the HST collected on those sales.
Cloud-based bookkeeping software can simplify this process, but software still needs to be set up and maintained correctly. Incorrect tax settings or poorly categorized transactions can create problems even when accounting software is being used.
